Staff is requesting City Council now approve the Adopting Resolution for the restoration and water quality improvements in the City's Big Canyon Nature Park adjacent to Jamboree Road. RECOMMENDATION: Adopt Resolution No. 2016-58, A Resolution of the City Council of the City of Newport Beach, California, Adopting Mitigated Negative Declaration No. ND2016-001 (SCH# 2016031011) for the Big Canyon Habitat Restoration & Water Quality Improvement Project (PA2016-046), pursuant to the California Environmental Quality Act, State CEQA Guidelines and City Council Policy K-3. FUNDING REQUIREMENTS: There is no fiscal impact related to this item. DISCUSSION: The proposed project area in Big Canyon Nature Park, located adjacent to the west side of Jamboree Road (Attachment B), has been documented as suitable for habitat restoration and enhancement. The reasons include stream channel incision; loss of floodplain connectivity; unstable stream banks; water quality impaired from metals, 6-1 Big Canyon Habitat Restoration and Water Quality Improvement Project — Adoption of Mitigated Negative Declaration (15X12) May 10, 2016 Page 2 toxics, nutrients, sediment, oil, grease and bacteria; and native riparian habitat now dominated by non-native invasive plant. This Big Canyon Restoration and Water Quality Improvement Project will (1) restore historic riparian habitat by removing non-native vegetation and replanting native species, (2) stabilize the creek and floodplain with engineered energy dissipation and erosion control measures, (3) improve water quality in Big Canyon Creek and Newport Bay with an infiltration wetland and isolation of seepage flows with high concentrations of selenium for diversion to the sanitary sewer, and (4) enhance public access and education within the Big Canyon Nature Park with improved trails, closure of illegal trails, and creation of diverse ecological habitats. If the City is successful in expeditiously securing the necessary Coastal Commission and other regulatory permits, construction could begin Fall 2016 with substantial completion by Spring 2017, followed by a 120 -day plant establishment and maintenance period. ENVIRONMENTAL REVIEW: The Big Canyon Habitat Restoration and Water Quality Improvement Project Initial Study/ Mitigated Negative Declaration (included in Attachment A) has been prepared by ESA, Inc. in accordance with CEQA, State CEQA Guidelines, and City Council Policy K-3. A copy of the MND is available on the City's website, at each Newport Beach Public Library, and at the Public Works Department at City Hall. The MND does not identify any project component that would result in a "potentially significant impact" on the environment per CEQA guidelines. Based upon the analysis of the Initial Study, the environmental categories within which the project would have either no impact or less than significant impact were: Aesthetics, Agricultural/Forestry Resources, Air Quality, Greenhouse Gas Emissions, Geology/Soils, Hazards/Hazardous Materials, Hydrology/Water Quality, Land Use/Planning, Mineral Resources, Noise Population/Housing, Public Services, Recreation, Transportation/Traffic, and Utilities/Service Systems. Based upon the analysis of the Initial Study, the environmental categories within which the project would have potentially significant impacts were Biological Resources and Cultural Resources. Specific mitigation measures have been included to reduce the potentially significant adverse effects to a less than significant level. The MMRP is a companion document to the MND and is included in Attachment A. The MMRP takes all the mitigation measures identified in the MND and identifies the schedule and the parties responsible for implementing those mitigation measures. The MND was made available for public review for a 30 -day comment period from March 4, 2016 to April 4, 2016. Comment letters were received from California Department of Fish and Wildlife (Attachment C), Regional Water Quality Control Board — Santa Ana Region (Attachment D), and Orange County Sanitation District (Attachment E). Comments 6-2 Big Canyon Habitat Restoration and Water Quality Improvement Project — Adoption of Mitigated Negative Declaration (15X12) May 10, 2016 Page 3 were also received from the City's Planning Division. Written responses to the three comment letters received and the City Planning Division comments were prepared (The responses to comments are included with Attachment A.) The comments and responses to comments to the MND do not change the determinations or represent a significant departure from the original document that would warrant recirculation of the MND, and staff recommends adoption of the MND and MMRP. NOTICING: As part of the MND public review process, the City mailed the Notice of Availability and Intent to Adopt an MND to the State Clearinghouse with a detailed description of the project. Notice was posted on site at the foot of the access road from Jamboree Road into Big Canyon Nature Park. Staff met with the General Manager at Park Newport Apartment Community. Staff also corresponded with the Bluffs Homeowners' Community Association and the Eastbluff Apartment Owners' Association, provided information and offered to attend community meetings as requested. Additionally, notice of the MND public review period and process was published in the Daily Pilot. The agenda item was also noticed according to the Brown Act (72 hours in advance of the meeting at which the City Council considers the item).

This Initial Study addresses the indirect, direct, and cumulative environmental impacts associated with the proposed project. The proposed project includes the following (1) restore historic riparian habitat by removing non-native vegetation and replace it with native plantings, (2) stabilize the creek and floodplain, (3) improve water quality in Big Canyon Creek and Newport Bay, and (4) enhance public access within the Big Canyon Nature Park. The project also includes maintenance of the proposed water quality features to ensure that the features are functioning as originally designed. 1.1 Statutory Authority and Requirements In accordance with the CEQA (Public Resources Code Sections 2100-21177) and pursuant to Section 15063 of Title 14 of the California Code of Regulations (CCR), the City of Newport Beach, acting in the capacity of Lead Agency, is required to undertake the preparation of an Initial Study to determine if the proposed project would have a significant environmental impact. If the Lead Agency finds that there is no evidence that the project, either as proposed or as modified to include the mitigation measures identified in the Initial Study, may cause a significant effect on the environment, the Lead Agency must find that the project would not have a significant effect on the environment and must prepare a Negative Declaration or Mitigated Negative Declaration for that project. Such determination can be made only if, "there is no substantial evidence in light of the whole record before the Lead Agency" that such impacts may occur (Section 21080(c), Public Resources Code). The environmental documentation is intended as an informal document undertaken to provide an environmental basis for subsequent discretionary actions upon the project. The resulting documentation is not, however, a policy document and its approval and/or certification neither presupposes nor mandates any actions on the part of those agencies from whom permits and other discretionary approvals would be required. The environmental documentation and supporting analysis is subject to a public review period. During this review, public agency comments on the document should be addressed to the City of Newport Beach. Following review of any comments received, the City of Newport Beach will consider these comments as part of the project's environmental review and include them with the Initial Study documentation for consideration by the Planning Commission of the City of Newport Beach. 1.2 Purpose The City of Newport Beach (City) has prepared this IS/MND to provide the public and responsible agencies with information about the potential environmental impacts associated with implementation of the proposed Big Canyon Creek Restoration and Water Quality Improvement Project. This IS/MND includes project -level analysis of the potential effects associated with the project. This IS/MND was prepared in compliance with Sections 15070 to 15075 of the California Environmental Quality Act (CEQA) Guidelines of 1970 (as amended) and California Code of Regulations, Title 14, Division, Chapter 3. In accordance with Section 15070, an MND shall be prepared if the Initial Study identifies potentially significant effects, but revisions in the project plans would avoid or mitigate the effects to a point where clearly no significant effects would occur. As the CEQA lead agency, the City has determined that an IS/MND shall be prepared for the proposed project. 6-19 CHAPTER 2 Project Description 2.1 Introduction The Big Canyon Restoration and Water Quality Improvement Project (proposed project) is located on a 6 -acre site in the eastern portion of the 60 -acre Big Canyon Nature Park at the downstream end of the Big Canyon Watershed in the City of Newport Beach (City), Orange County, California (Figure 1). The Big Canyon Watershed covers approximately two square miles located on the east side of Upper Newport Bay. Big Canyon Creek winds through the Big Canyon Nature Park in a general southeast to northwest direction and then discharges into Upper Newport Bay. Big Canyon is the only natural, undeveloped portion of the Big Canyon watershed and the only significant remaining natural canyon on the east side of Newport Bay. The upper 45 -acre parcel is owned by the City of Newport Beach. The lower 15 -acre portion of the Nature Park is owned the California Department of Fish and Wildlife and is a part of the Upper Newport Bay State Ecological Reserve. 2.1.1 Project Background The City has contemplated restoration efforts within Big Canyon for over a decade. Currently, the City has funding for the restoration efforts that are part of Phases IA and IB (proposed project). Potential future restoration efforts could also be proposed as a separate project, if future funding is available. The proposed project is currently being planned in coordination with a Resource and Recreation Management Plan (RRMP) being prepared by the Irvine Ranch Conservancy under contract with the City of Newport Beach for the Big Canyon Nature Park. The RRMP provides a framework for restoration and recreational improvements in the Nature Park that will be consistent with the requirements of the Natural Community Conservation Plan/Habitat Conservation Plan (NCCP) for the Central and Coastal sub -region of Orange County in the event the City elects to incorporate the Nature Park into the NCCP. Potential future restoration efforts within Big Canyon would also be coordinated with the RRMP. 6-20 f� i SOURCE: City of Newport Beach, ESRI Irvine Costa Mesa 55 VV 45 off` Nc Project Location Newport Beach N,'i,, Bay ...�..-4._ PACIFIC OCEAN UUn Dr Gary 3or�lta Sal Joaquin Rd ig Canyon Habitat Restoration and Water Quality Improvement Project.

D130934 Figure 1 Regional Location Map 6-21 The potential future restoration efforts could provide benefits to Big Canyon in addition to those associated with the proposed project. These benefits could include water quality improvements in Big Canyon Creek, restoration of natural creek channels impacted by hydromodification, restoration of riparian and inland alkaline non -tidal marsh habitat, removal of non-native vegetation and replacement with native plantings, remediation of selenium -laden sediment within former freshwater ponds, creation of new transitional habitat to allow for future adaption of coastal estuarine habitat due to sea -level rise, reduction of favorable mosquito breeding habitat, and improvements and protection of public access within the natural areas of the Big Canyon Nature Park, including coastal areas that will be subject to future inundation due to sea -level rise. If funding is available, the City anticipates the preparation of a feasibility analysis to develop the least impactful and most cost-effective approach to the freshwater ponds for the fixture restoration efforts. These fixture efforts could include the protection of the biological resources within the creek and downstream estuary by addressing the sediment and reeds within these ponds and restoring the area of the future efforts. This potential future area currently contains invasive pepper trees, and the City contemplates removal of them so that the area could be restored to a transitional habitat to allow for adaptation of the coastal estuary due to sea -level rise. Based on projected sea -level rise, this area of invasive pepper trees could be inundated in about 50 years. Phases IA and IB, the current project, include the implementation of a creek and riparian habitat restoration, habitat creation and enhancement, stormwater treatment wetland, dry -weather flow diversions, culvert improvements, and trail planning in the upper portion of the Big Canyon Nature Park. Implementation is scheduled for 2016-17. 2.1.2 Purpose and Need for Project The Big Canyon Restoration Project — Phases IA and IB will: (1) restore historic riparian habitat by removing non-native vegetation and replace it with native plantings, (2) stabilize the creek and floodplain, (3) improve water quality in Big Canyon Creek and Newport Bay, and (4) enhance public access within the Big Canyon Nature Park. Restoration and water quality improvements in Phase I will proceed potential future restoration efforts in the remaining downstream areas of the watershed. 2.1.2.1 Restore Historic Riparian Habitat Big Canyon Creek has been documented as suitable for habitat restoration and enhancement due to channel incision, loss of floodplain access, unstable banks, poor water quality, and more than anything invasive species. Large portions of the riparian habitat are dominated by non-native invasive species. This in turn has impacted the habitat quality of the riparian habitat in and along Big Canyon Creek within the project area as well as in the downstream reaches of the Nature Park. 2.1.2.2 Creek and Flood Plain Stabilization Urbanization in the Big Canyon watershed has resulted in increased peak and sustained peak storm flows that have resulted in hydraulic modification of the Big Canyon Creek within the 6-22 project limits. Downstream of the Jamboree Road culvert, Big Canyon Creek has responded to hydromodification by incising into its historic channel bed and eroding channel banks in the upper reach of the creek. Channel incision has reduced floodplain connectivity in the adjacent riparian community that requires periodic inundation to support native biological species and habitat conditions. Continued erosion and channel cutting will result in unstable embankments. Flooding has also occurred historically at the site and has resulted in damage to Back Bay Drive. Without the proposed creek and watershed restoration measures, the ongoing physical, chemical and biological processes will result in additional bank and bed erosion, continued loss of riparian habitat, reduced water quality in the creek and in Newport Bay, and loss of opportunities to provide effective educational and recreational elements that serve the wider Orange County. In addition a mosquito vector habitat is created when wet weather flows from Jamboree Road discharge through a storm drain outfall to a scour pond in the creek's riparian corridor. This project addresses this mosquitos breeding habitat by eliminating the scour pond. 2.1.2.3 Water Quality Improvements During wet weather, roadway -related pollutants (e.g., metals, sediment, oil and grease) enter Big Canyon Creek from thoroughfares such as Jamboree Road and impact creek water quality. The project includes measures to reduce metals and sediment loading into the creek and Bay from stormwater flows from Jamboree Road. Big Canyon Creek is listed as an impaired waterbody for selenium and a total maximum daily load (TMDL) has been established for the creek. The receiving water for Big Canyon Creek is Newport Bay, which is listed as an impaired waterbody for metals, toxics, nutrients, and bacteria. TMDLs have also been established to address these impairments. Big Canyon Creek, which drains the Big Canyon Watershed, is one of the few perennial streams that discharge to Upper Newport Bay. Concentrations of selenium above water quality guidelines have been measured in dry weather flows in Big Canyon Creek. The City has developed and is implementing a selenium reduction program in the watershed that includes dry weather diversions and other measures to reduce the selenium concentrations in the creek and into Upper Newport Bay. This project includes additional measures to substantially reduce selenium loading in dry weather flows as part of the selenium reduction program. To address these issues, the proposed project would construct a bioretention cell water quality treatment wetland that would treat wet weather flows and would also minimize the storm drain - associated vector habitat in Big Canyon Creek. Additional water quality measures include the construction of a dry weather flow diversion that re-routes flows of low selenium concentration around identified sources of high selenium and return these better quality flows back into the creek downstream. Seeps that are sources of high selenium will be passively collected and diverted to the sanitary sewer. Without the proposed water quality measures as part of Phase IA and IB of the Big Canyon Restoration Project, impacts to water quality and biological beneficial uses will continue. The 6-23 success of the planned restoration efforts as part of this phase and potential future downstream phases depends on addressing the existing water quality issues. These measures are needed for the long-term sustainability of the restoration of Big Canyon. 2.1.2.4 Public Access Enhancements Big Canyon Nature Park is used by residents and visitors for passive recreation. This is an important destination for thousands of children participating in the Orange County Department of Education Inside the Outdoors program. Inside the Outdoors provides watershed educational activities for grade school children throughout the county including disadvantage communities. As the largest undeveloped canyon adjacent to Newport Bay, it has the potential to become an integral part of the Upper Newport Bay State Ecological Preserve and to provide unique opportunities for the public to learn about the diversity of biological resources and environmental protection within a short walking distance. At present, the upper portions of the Nature Park are not attractive and rarely visited by the public. Along with habitat restoration, trail improvement and information signage will provide an enhanced experience of the different ecotones in a coastal watershed. 2.2 Project Location and Setting The proposed project is located within the City of Newport Beach, on a 6 -acre site in the eastern portion of the 60 -acre Big Canyon Nature Park. As shown in Figure 1, the project site is east of Upper Newport Bay, west and east of Jamboree Road and includes Big Canyon Creek. Primary regional access to the project site is provided by State Route 73, which runs north -south approximately 2 miles north of the project site, and State Route 1, which runs north -south approximately 1.25 miles south of the project site. Sub -regional access is provided via Jamboree Road, Ford Road, and San Joaquin Hills Road. The project site is bounded by residential developments on the bluffs to the north and south. Land uses within the project vicinity include residential, recreational open space, golf courses, and commercial developments (Figure 2). Located on the east side of Upper Newport Bay, Big Canyon Creek winds through the Big Canyon Nature Park in a general southeast to northwest direction and then discharges into Upper Newport Bay. The Big Canyon watershed is roughly 1,300 acres extending roughly 3 miles east from Back Bay Drive into the San Joaquin Hills. Big Canyon is the only natural, undeveloped portion of the Big Canyon watershed and the only significant remaining natural canyon on the east side of Newport Bay. This 45 -acre parcel contains native and non-native habitat and an array of hiking trails, and is owned by the City of Newport Beach (Figure 3). Directly downstream of the Project Area, the lower 15 -acre portion of the Nature Park is owned by the California Department of Fish and Wildlife (CDFW) and is a part of the Upper Newport Bay State Ecological Reserve. Big Canyon Nature Park is located in the Upper Newport Bay State Marine Conservation Area (SMCA) and is part of Southern California's coastal estuarine environment. Newport Bay discharges adjacent to the Newport Coast Area of Special Biological Significance (ASBS). 6-24 Sall EraWa sEACt t H f �a' Z. i.00 SOURCE: USGS 7.5' Topo Quad Newport Beach, 1977 Big Canyon Habitat Restoration and Water Quality Improvement Project.

D130934 Figure 3 Project Aerial Map The Project Area is characterized topographically by steeply sloping bluffs and a narrow, moderately -sloped floodplain; slopes range in elevation from 20 to 75 feet above mean sea level and the canyon creek ranges in elevation from below mean sea level to 25 feet above mean sea level. A perennial stream identified as Big Canyon Creek is present within the Project Area and supports degraded riparian habitat. The Project Area supports six plant communities, as well as disturbed and developed areas (Figure 4, Vegetation Communities). These plant communities include southern riparian forest, freshwater march, alkali meadow, Diegan sage scrub, non-native grassland, and ornamental habitat—of these, southern riparian forest, freshwater march, alkali meadow, and Diegan sage scrub habitats are considered to be sensitive plant communities. Sensitive habitats are those considered to support unique vegetation communities and/or special -status plant and/or wildlife species, or function as corridors for wildlife movement. The southern riparian forest habitat is heavily impacted by the invasion and establishment of invasive trees and understory vegetation. A total of 194 species of invasive and non-native grasses, forbs, and trees have been identified within the Big Canyon Nature Park (Dudek 2015). The Big Canyon Project Area is bound on three sides by development. On the east side of Jamboree, the Project Area is bound by the golf course to the east and south, and a condominium complex to the north. On the west side of Jamboree Road, residential development is located at the north and south side of the Project Area. To the west, the Big Canyon Nature Park extends to Upper Newport Bay State Ecological Reserve. 6-27 w 3 Project Boundary Parcel Boundary v Feet Vegetation Communities and Land Cover Types 6 AM, Alkali Meadow (0.10 acre) CSS, Coastal Sage Scrub (1.53 acres) DEV, Developed (0.04 acre) DIST, Disturbed (Trail) (0.40 acre) NNG, Non-native Grassland (2.83 acres) ORN, Ornamental (0.78 acre) SRF, Southern Riparian Forest (4.00 acres) SOURCE: ESA, ESRI %Z40 Big Canyon Habitat Restoration and Water Quality Improvement Project.

D130934 Figure 4 Vegetation Communities Map 6-28 2.3 Project Overview and Design The proposed project has several objectives including: • Restore and Enhance Riparian Habitat • Improve Water Quality • Reduce Flood/Erosion/Sedimentation Damage • Encourage Public Participation and Provide Education • Provide Recreational Opportunities In order to meet these objectives, the proposed project includes the following elements: • Creek Restoration and Riparian Habitat Creation & Enhancement — The project proposes to conduct creek restoration activities that will include floodplain restoration, streambank stabilization, and habitat restoration. Floodplain restoration and streambank stabilization activities will result in increased flood flow attenuation, stabilization of the north bank of the main channel, and creation of an active braided riparian floodplain. The north creek bank at the inlet will be stabilized using natural bioengineering techniques. Riparian habitat will be restored directly downstream of the floodplain restoration area through the removal of invasive trees, soil modification to reduce plant -limiting sodium levels, and replacement with native riparian species. • Riparian Habitat Creation Activities — Riparian habitat creation activities will also be conducted directly to the southwest of the proposed bioretention cell. This area will be graded down to allow for riparian trees to access existing groundwater. Riparian habitat enhancement will include removal of upstream and adjacent sources of Brazilian peppertree both east of Jamboree Road and north of the creek. • Stormwater Water Quality Treatment Bioretention Cell — The project includes the construction of a water quality treatment bioretention cell that will treat wet -weather flows from Jamboree Road and reduce the storm drain -associated vector habitat in Big Canyon Creek. The basin will be vegetated with coastal sage scrub on the outer banks and vegetated with native riparian forbs, grasses, and shrubs in the inner basin. These species will have the ability to sequester toxins and tolerate flooded conditions for limited periods of time. The basin will be periodically maintained per an approved Operation and Maintenance Plan. • Dry Weather Water Quality Selenium Reduction Measures — A dry weather flow diversion that re-routes flows of lower selenium concentration around identified sources of high selenium and return these better quality flows back into the creek will be constructed as part of this project. Dry weather flows will be diverted from an underground culvert on the east side of Jamboree Road and routed through an above ground pipe along the south bank of the creek and through the storm drain culvert under Jamboree Road. The pipe will discharge on the west side of Jamboree Road into the 6-29 floodplain that will be graded as part of this project. Seeps that are sources of high selenium will be passively collected and diverted to the sanitary sewer. • Infrastructure Improvements — The Project will also be constructed in coordination with infrastructure improvements by the Orange County Sanitation District (OCSD). The improvements are shown on Figure 3 and include the extension and improvement of the existing access road along the toe of slope along the west side of Jamboree Road. The access road improvements will be used access and maintain the sanitary sewer manhole located to the north of the existing culvert outfall. The construction of the access road to and over the existing culvert under Jamboree Road requires the extension of the culvert as shown on Figure 3. A concrete stilling pool will be located at the end of the culvert extension to dissipate hydraulic energy as the stormwater transitions from flow in the culvert and discharges to the regraded floodplain. This stilling pool will be periodically maintained to remove sediment and vegetation. Water from the stilling pool will exit via a rip rap energy dissipater. OCSD will also install a permanent dosing station and access area located to the south of the proposed habitat creation area. • Community Access Improvements and Educational Opportunities — The extended access road will provide an official trail where the public can learn about and enjoy the native habitats. In addition, an 8 -foot -wide bicycle path connector will be installed to provide access directly from Jamboree Road. In addition, the maintenance road at the top of the bioretention cell will also be used as a side viewing trail with interpretive signs installed. Visitors using this trail will cross from the south to the north side of the creek via the OCSD constructed turnaround area over the culvert, and follow a footpath on the north side of the creek. The footpath on the north side of the creek will continue within the coastal sage scrub habitat, following existing ad hoc trails that will be expanded to approximately 42 -inches wide. Trails allow for educational opportunities regarding water quality and creek restoration activities, and through the installation of signage and as - needed fencing, will keep the public out of sensitive habitats. 2.4 Project Components As shown in Figure 5, the proposed project consists of habitat restoration, creation and enhancement of riparian habitat, water quality improvements, and infrastructure and trail improvements. 2.4.1 Creek Restoration, Creation and Riparian Habitat Enhancement This project consists of creek restoration and riparian habitat creation and enhancement activities including stream bank stabilization, floodplain restoration, habitat creation, and restoration of riparian habitat through invasive plant removal, soil remediation and revegetation. 6-30 2.4.1.1 Floodplain Restoration & Streambank Stabilization Directly downstream of the new culvert placement and stilling basin where Big Canyon Creek flows into the Project Area, the project will create and restore the creek's active floodplain (Figure 6, Riparian Habitat Restoration Areas). The main channel is currently incised and is confined to the incised narrow creek bed. The existing area to the south of the creek would be lowered by approximately 6 feet to create a floodplain 2 to 3 feet above the low -flow channel to allow for frequent inundation during high-flow events. The 150 feet of channel and floodplain downstream of the stilling basin will be restored to eliminate unstable eroding banks and a disconnected floodplain. A bankfull channel has been sized using Dunne and Leopold's (1978) regional hydraulic geometry for California creek dimensions, cross-checked against the downstream stable section as a reference reach. For a watershed of 1.7 square miles (as delineated using the USGS StreamStats web application), this produces a bankf ill width of 19 feet and a bankfull depth of 1.8 feet (rounded to 20 feet and 2 feet, respectively), very similar to the downstream channel width and depth in the more stable area. For the restored reach, the existing channel invert elevation was retained. The channel will be realigned away from the eroding and undercut north bank into the center of the floodplain, and a new floodplain will be created on both banks. The floodplain and channel will be sized so that flows exceeding the 2 -year recurrence event start to inundate the floodplain. On the south bank (river left, looking downstream) a 20 -foot -wide floodplain will be created by cutting into the existing over -steepened bank and upland terraces currently dominated by non- native grasses as well as degraded riparian habitat. There will be a net reduction in fill within the floodway, and an increase in both conveyance and frequently activated floodplain. On the north bank (river right, looking downstream) the floodplain will be stabilized by adding vegetated soil lifts. Encapsulated vegetated soil lifts planted with willows and other native vegetation will be used to construct and protect the banks, and to provide erosion control. The vegetated soil lifts will be constructed in 1 -foot -thick lifts containing the native alluvial soil from the site and amendments, with each lift encapsulated in coir fiber that will biodegrade over the first 2-3 years, once the incorporated native riparian vegetation has established. Each lift will be separated from the next by a layer of locally sourced native live willow stems that will grow following installation. For the cut banks (river left) willow brush mats will be placed over the cut bank and secured with biodegradable coir fabric, then secured with biodegradable rope and wooden stakes. Both cut and filled banks will be reinforced with biotechnical materials up to the 100 -year water surface elevation. This will serve to stabilize the grade and act as a planting medium for the growth of riparian vegetation. 6-31 • • • \ • ®• • = ••e r, 440-102-06 440-102-07 Its -02 i ' ��,• / nO ® i ; + n I \ r/ %% 'A ® ® • ® D 4�0�92� //�i • • • �� • �1 :1 440-251 440-102-12 442-181-57 442-251-01 :442-181-02 442-181-01 442-181-03 442-181-04 442-181-61 442-181-05 442-032-60 442-032-51 442-032-59 Q Project Boundary Surveyed Invasive Trees Project Components Phase 1A: Riparian Habitat Restoration .. • (442 ® Parcel / APN # o Ash Staging/Storage Area • Canary Island date palm Riparian Habitat Restoration Area \ New Grading Features • Eucalyptus Phase 1B: Mitigation Areas — Existing Sewer Features • Fig Riparian Habitat Creation Area -- Water Line • Goldenrain tree Riparian Habitat Enhancement Area 440-251-05 440-251-04 � Proposed Project Design • Mexican fan palm Phase 1113: Facilities/Roadways Proposed Trails Brazilian pepper Access Road and Infrastructure Improvement 442-181-13 o ot too --- 3.5 -foot wide Trail Bioretention Cell I I 442-181-56 8 -foot wide Trail iiiii�l Dosing Station Feet 15 -foot wide Trail SOURCE: Burns & McDonnell; Dudek; ESA Big Canyon Habitat Restoration and Water Quality Improvement Project. 130934 Figure 5 Project Components and Phasing 6-32 This page left intentionally blank 6-33 2.4.1.2 Riparian Restoration & Soil Modification Directly downstream of the floodplain restoration area, the riparian habitat will be restored to its full functioning system (see Figure 6 and Figure 7, Habitat Mitigation Areas). Under current conditions, invasive trees and an extensive understory of non-native forbs and grasses have been documented. Bermuda grass (Cynodon dactylon), periwinkle (Vinca major), pampas grass (Cortaderia selloana), and English ivy (Hedera helix) are just a few of the highly invasive grasses and forbs found under the existing canopy. These invasives are better able to compete under the high -saline soil conditions that are found within Big Canyon. Brazilian peppertree is the most prevalent invasive tree species found in the canyon. The origins of this seed source can be traced to two sources: (1) east of Jamboree Road, Brazilian peppertree has established on the slopes of the Big Canyon drainage and adjacent upland area, with the seed source directly flowing into the canyon; and (2) the west side of Jamboree Road directly to the north of the creek also has this species growing on the slopes. The trees, forbs, and grasses will be aggressively removed as part of this project. Mature trees will be removed during mass grading and isolated individuals will be killed in place without soil disturbance. Soil testing results have indicated extremely high levels of sodium, boron, and sulfur in the soils. Brazilian pepper tree's high tolerance for these extreme levels of normally plant -inhibiting levels indicates the reason this species is so successful in Big Canyon. Following invasive removal, the soil will be amended to levels where native riparian vegetation can persist. The soil amendment regiment will be incorporated directly into the top layers of soil following plant removal. Details of the soil modifications will be included in the Habitat Restoration Plan prepared for this project. Following soil modification, all areas will be actively planted, seeded, and maintained, with topically applied soil treatments continuing through plant establishment, as prescribed. 2.4.1.3 Wetland/Riparian Habitat Creation Additional riparian habitat will be created to the southwest of the proposed bioretention cell. This will result in the expansion of contiguous riparian habitat, and will serve as part of the required mitigation as replacement for some of the habitat lost as a result of implementation of other components of this project (see Figure 7). This area has been previously disturbed and consists of early successional forbs and grasses, providing low habitat value. Groundwater has been measured in this area with a temporary piezometer at 5-7 feet below the existing ground surface. The area will be graded to lower current ground elevations to access this permanent water source to an elevation of approximately 39 feet mean sea level. A reduction of the elevation within the creation area and in the existing riparian area to the west of the creek will bring the ground level closer to the groundwater table, thereby allowing for establishment of riparian vegetation that will be planted following grading and soil preparation activities. The discharge of the stormwater treatment wetland will also be routed to this area to provide for periodic inundation during storm events. The areas will also be subject to flooding during larger storm events, but will not pond water or create a vector issue. 6-35 7 5 r r may.

The transportation -related pollutants are currently conveyed to the receiving waters in Big Canyon Creek from a variety of sources, including vehicles, road maintenance, maintenance facility runoff, and landscaping maintenance. Vehicles are known to produce a variety of pollutants that can have a negative impact on water quality in the receiving waters to which they drain. Metals such as copper and zinc can build up on road surfaces through brake and tire wear; other metals such as cadmium, chromium and sometimes lead can be deposited on road surfaces from paint on vehicles and streets. Metals often bind to sediments, trash, and debris on road surfaces; these can be carried into waterways during storm events. In addition to pollutants associated with vehicles, landscaped areas associated with or adjacent to streets (e.g., median, parkway, and residential landscaping) can be sources of pollutants such as pesticides, nutrients (particularly nitrate and phosphorus), and fecal -indicator bacteria (all of which are known to be associated with urban landscaping, which is found throughout the 11.1 -acre Jamboree Road drainage area). These pollutants can be transported to receiving waters during storm events. Finally, in addition to direct deposition to the road surface, street surfaces and adjacent walkways and landscaped areas can be impacted from vehicle emissions through atmospheric deposition of pollutants such as the dissolved fraction of metals and organics (e.g., polynuclear aromatic hydrocarbons (PAHs). According to national and regional best management practices (BMPs) manuals (e.g., the California Stormwater Quality Association BMP handbook), the technology proposed in the stormwater treatment system has been shown to be effective in treating a variety of pollutants associated with transportation runoff, including trash, sediment (and attached pollutants), nutrients and organics such as PAHs and pesticides, and fecal -indicator bacteria. The stormwater treatment system would consist of a primary stormwater treatment structure and a bioretention cell, as described below. Primary Stormwater Treatment Structure A primary treatment structure would be constructed to receive runoff from existing stormwater inlets serving Jamboree Road. The contributing drainage area draining to the primary stormwater treatment structure is approximately 11.1 acres. The purpose of this structure is to trap, contain, and pretreat trash, total suspended solids (TSS), and free oils prior to conveyance to the bioretention cell. Located adjacent to Jamboree Road, the primary stormwater treatment structure 6-37 would be approximately 40 square feet in size and include three chambers. The first chamber would be designed to collect dense solids and trash (floatables); the second would collect sediment and finer solids; and the third would provide storage and delivery of dissolved phase constituents to the bioretention cell. Manhole access ports would be installed for periodic removal of trash and sediment from the three chambers. Bioretention Cell The bioretention cell is an underground, modified constructed wetland that would be designed specifically to treat the suite of transportation -related pollutants found in urban watersheds. The bioretention cell would be constructed to treat stormwater flows that discharge from the primary stormwater treatment structure. The surface area of the bioretention cell would be approximately 0.47 acres in size when measured at the top of the bioretention cell berm (see Figure 5). The bioretention cell would be designed to capture and treat the stormwater that discharges from Jamboree Road. It will treat approximately 0.75 inches of stormwater in a 24-hour period. The bioretention cell will attenuate and reduce the peak discharge rate to Big Canyon Creek during storm events. The bioretention cell will consist of (from top to bottom) layers of soil, sand, and gravel, underlain by an impermeable liner. The top of the cell will be planted with native vegetation. The soil layer would be approximately 2 to 3 feet thick and would be underlain by a 6 -inch sand filter bed located between the bioretention soil and drainage gravel layer situated in the bottom of the bioretention cell. The bottom 12 -inch gravel drainage layer will form the base layer of the bioretention cell and will be underlain by a geotextile cushion. The entire bioretention cell will be underlain by a 60 -MIL high-density polyethylene (HDPE) liner. The bioretention cell would be divided into two subcells, hydraulically separated from one another by an impermeable barrier, to enable the comparison of water quality effluent between the cells. One subcell would be designed to be free draining and the second subcell would be designed such that approximately 12 inches of treated water would remain on the liner and within the gravel drainage layer. Stormwater will flow via gravity from the primary stormwater treatment structure to the top of the subcells through a series of perforated and solid inflow PVC pipes. Pollutants would be removed from stormwater as it flows down through the treatment media. Treated water would flow from the bottom of the bioretention cell through a series of PVC pipes into a newly created wetland habitat area located to the south of the bioretention cell (see Figure 5). The wetland habitat area will be graded to allow for infiltration to groundwater and for surface flow return to Big Canyon Creek. Table 2-1 summarizes the anticipated pollutant reductions from stormwater (wet weather) anticipated from the primary stormwater treatment structure and bioretention cell.

The interior of the bioretention cell will be periodically maintained, per the approved Operation and Maintenance Plan. This may include the cleanout of vegetation or replacement of soil to ensure continued water quality improvement. 2.4.2.2 Selenium Reduction Measures in Dry Weather Flows (Dry Weather and Seeps / Collection and Diversions) Dry Weather Flow Diversion The purpose of the dry weather flow diversion is to limit the contact between dry weather flows with low selenium concentrations with groundwater seepage flows that contain much higher selenium concentrations. Monitoring investigations conducted by the City in 2015 determined that seepage flows with high selenium concentrations occur in the creek on the east side of Jamboree Road between the proposed diversion and the entrance to the existing culvert. High selenium seeps also occur on the west side of Jamboree Road just downstream of the mouth of the existing culvert (City of Newport Beach 2015, unpublished data). The proposed project proposes to passively collect these high selenium concentration seeps and direct them to the sanitary sewer. The estimated seepage flows are anticipated to be less than 10% of the total current dry weather flows in Big Canyon Creek. Therefore, approximately 90% of the current dry weather flows will be returned to the creek. Diverting the high selenium seepage flows will substantially reduce in -stream selenium concentrations in the downstream creek flowing through the restoration area. No significant impact is expected to the riparian habitat within the section of the creek between the diversion and the returned cleaner dry weather flows as groundwater seepage will sustain the willow vegetation and planned invasive removal and revegetation will further enhance this section of the creek to the east of the culvert under Jamboree Road. 6-39 Dry weather flows with lower selenium concentrations will be diverted in a new diversion structure located on the Big Canyon Golf Course. The diversion structure will divert about 0.5 cfs and allow higher flows to pass through the diversion structure. The diversion flow line will include a valve that will enable the diverted flows to be reduced and adjusted if necessary. The diversion line will flow via gravity and will be installed along the existing southern slope of the ditch north of the golf course maintenance yard. No grading and soil disturbance is anticipated. The diversion line will be at grade on the surface of the slope and will be anchored to the slope using an anchorage system. The anchor system will be installed along the existing disturbed top of slope adjacent to the golf course maintenance yard fence. The diversion line will transition from the slope into the east side of the Jamboree Road existing culvert. The diversion line will be installed inside the existing Jamboree Road culvert and inside the new culvert extension. The diversion line will discharge dry weather flows into the restored floodplain as shown in Figure 5, to provide surface water to that area. Numerous studies and assessments on selenium loads and sources in Big Canyon Creek have been conducted. Reeder (2011) provided a comprehensive assessment of the geology, hydrology, and water quality related to selenium sources in the watershed from studies conducted as early as the 1970s through 2011. Since then, additional studies have been conducted in the watershed on flow rates (Weston 2013), water balance in the upper watershed (DBS&A 2015), and specific selenium source identification assessments in the lower portion of the watershed (City of Newport Beach, unpublished data). Based on long-term monitoring conducted in 2012 (Weston 2013), the approximate base dry weather flow rate of Big Canyon Creek at Jamboree Road is 0.420 cfs. The proposed dry weather flow diversion upstream of Jamboree Road is not anticipated to impact the natural creek function. It will divert low selenium water around a stream reach of approximately 170 feet just upstream of Jamboree Road (Figure 5) where high selenium groundwater seeps have been identified (City of Newport Beach, unpublished data). Groundwater originating in this reach is estimated to contribute less than ten percent of the dry weather baseline flow in the creek, which will be diverted to sanitary sewer. The wet weather function of the creek will not be affected by the dry weather flow diversion. To support the design of the culvert extension and stilling basin, wet weather design discharge rates were determined. The Big Canyon Watershed drains approximately 1,062 acres. The modeled 100 -year flow rate is approximately 2,510 cfs. The 10 -year flow rate is 1,680 cfs and the 2 -year flow rate 1,260 cfs. The diversion line may be extended to the bio -infiltration cell (if slopes allow) to enable irrigation of native vegetation on the surface of the bioretention cell during the plant establishment period and for persistence of the vegetation. Seep Water Flow Collection and Diversion Seeps containing high concentrations of selenium have been observed along the north and south banks along a 170 -foot reach of the creek on the east side of Jamboree Road near the existing culvert (City of Newport Beach, unpublished data). The seep flows will drain through the existing culvert and the new culvert extension and collect in a low point in the bottom the stilling basin MM floor. As the seep water collects and pools, it will then spill over into vertical open topped risers or similar system and drain into the OCSD sewer. The design will enable sediment to settle out and collect in the stilling basin floor while allowing the seep water to discharge to the sewer. The seep water diversion system will be designed such that the system can be shut off prior to precipitation events. The seep water diversion system will be designed such that the pooled water in the stilling basin floor is limited in extent to minimize mosquito vector habitat. Seepage containing high concentrations of selenium is also indicated based on water quality results, immediately downstream of the existing culvert on the west side of Jamboree Road. In order to address this source of high selenium in this area that corresponds to the new culvert extension and stilling pool, seeps will be passively collected and diverted via gravity to the OCSD sewer. Seepage that would otherwise discharge into the creek will be intercepted and collected from the gravel layer that forms the bedding material for the new concrete box culvert extension and the bedding material for the bottom of the concrete stilling basin. Perforated HDPE collection pipes will be installed in the gravel bedding material to convey water to a flow metering structure prior to discharge to the OCSD sanitary sewer. The seepage flow into the sewer is anticipated to be intermittent and the flow is rate anticipated to be low (in the 0-10 gpm range) due to the relatively low permeability of the soil in this area. The seepage collection lines include a valve to enable the collected flow to the OCSD sanitary sewer to be controlled. If the flow rate is higher than anticipated, the flow will likely be reduced through coordination with OCSD. 2.4.3 Infrastructure Improvements 2.4.3.1 Orange County Sanitation District Access Road and Dosing Facility The Project will also be constructed in coordination with infrastructure improvements requested by the Orange County Sanitation District (OCSD) that include the extension and improvement of the existing access road along the toe of slope along the west side of Jamboree Road and the construction a dosing station for odor control. A 12 -foot wide gravel roadway would be constructed to facilitate access to three OCSD manholes including a manhole located to the north of the existing culvert outfall. To provide access to this manhole, the existing culvert beneath Jamboree Road will be extended approximately 75 feet and an access roadway will be constructed on top of the culvert. The new gravel road would parallel Jamboree Road and connect to the existing gravel access road on the south end of the site. The gravel access road will also serve as pedestrian trail which is consistent with existing gravel roads in Big Canyon to serve the dual purpose of manhole access and pedestrian trails. The culvert extension will include a concrete stilling basin at the end of the culvert extension. The purpose of the stilling basin is to dissipate hydraulic energy during wet weather storm flow events. The stilling basin will be constructed with reinforced concrete and will include a concrete access ramp to enable access for maintenance. Maintenance activities will include sediment and debris removal from the stilling basin during dry weather. 6-41 An automatic chemical -dosing station would be constructed near the beginning of the access road extension. The dosing station consists of a 12 -foot high tower, 8 -foot diameter that would be constructed on a 20 -foot by 20 -foot pad, and a gravel access road as needed to access the station. Native plants will be planted around the facility. The station would be maintained on a monthly basis. A vehicle access path that doubles as the hiking trail would be constructed as a part of the proposed project to provide maintenance access to the infrastructure improvement components. 2.4.3.2 Community Access Improvements and Educational Opportunities Public access to the project site and surrounding environs is currently provided by existing hiking paths in Big Canyon Nature Park. The project includes providing improved and new trails for public access both on the north and south side of the creek. This new trail will allow for educational opportunities regarding water quality and creek restoration activities while keeping trails out of sensitive habitats and restored and enhanced riparian corridors. Preliminary public access and walkway signage and locations has been developed from previous efforts and will be incorporated in this project. The proposed OCSD access road will serve to connect the existing gravel path over the creek to connect with an improved trail on the north side of the creek. In addition, a bicycle path connector has been incorporated into this design to allow for direct access from Jamboree Road. Interpretive elements include key features such as a viewing area on the bio retention cell maintenance road, and informational signage. This plan is consistent with on-going efforts planned for the Big Canyon Watershed in consultation with the City, environmental organizations including the Newport Bay Conservancy and Irvine Ranch Conservancy, and the appropriate regulatory agencies. 2.5 Construction Activities and Schedule Project construction is expected to begin in Fall 2016 and will include the infrastructure components of the project, habitat restoration, and habitat mitigation implementation. Construction will be complete by March 31, 2017 to avoid impacts during the nesting season. Planting of all restoration and mitigation areas will take place once grading has been completed (see Table 2-2). Construction activities would commence with the installation of construction stormwater pollution prevention BMPs in accordance with the project Stormwater Pollution Prevention Plan (SWPPP). Following the installation of stormwater BMPs, project construction work would occur in phases for a duration of five to six months. The following schedule presents the construction phases, the activities to be completed under each phase, and the duration of the activities. Several activities will run concurrently to achieve the overall construction schedule of approximately five months. 6-42 Phase Activity Duration Month 1 Month 2 Month 3 Month 4 Month 5 Mobilization & Site preparation 1-2 weeks Earthwork clearing & grubbing Excavation and 2-3 weeks grading Drainage Culvert extension 4-6 weeks Structures and Piping Dry weather diversion 2-3 weeks Construction structures and external piping Water Quality Bioretention cell liner 1-2 weeks System and piping Construction Bioretention cell media 1-2 weeks placement Bioengineering 1-2 weeks structure construction OCSD Scope OCSD dosing station 4-6 weeks installation Restoration Site vegetation 3-4 weeks restoration Approximately 5 acres would be disturbed during project construction. Earthwork cuts are anticipated from the widened floodplain downstream and from the south bank of the Big Canyon Creek and the wetland habitat area. The total earthwork cut volume is approximately 4,000 cubic yards. Earthwork fills are anticipated for the bioretention cell berms and OCSD access road. The anticipated fill volume for mass earthwork is approximately 8,000 cubic yards. The net total volume import (soil and bioretention cell media) is approximately 4,000 cubic yards. Haul trucks would be used to transport earthen material used to construct the project. These haul trucks would access the site from the intersection of San Joaquin Road and Jamboree Road west on San Joaquin Road to Back Bay Drive, and then travel north on Back Bay Drive to the Big Canyon Trail maintenance road entrance. Trucks would follow the maintenance road east to the construction staging area as shown in Figure 5. It is estimated that approximately 40 daily haul truck trips and up to 900 to 1,000 total haul truck trips for material deliveries would occur over the course of construction. Approximately eight employees would be present on the project site at any given time during construction, including a construction superintendent, up to two laborers, up to three equipment operators, and up to two haul truck drivers. Typical equipment required for construction of the project would include a loader, back hoe, dozer, compactor, chipper (mulch), haul trucks, and a water truck. Construction is expected to occur between the hours of 7:00 a.m. and 6:30 p.m. Monday through Friday and 8:00 a.m. and 6:00 p.m. on Saturdays as set forth in the City of Newport Beach's Municipal Code 10.28.040, Construction Activity — Noise Regulations. No construction would occur on Sundays or federal holidays. Construction activities will be coordinated with erosion control and surface water diversion to prevent soils loss, channel instability, discontinuity of water supply during dry weather season, 6-43 and flood damages during major wet season events. A Water Quality Management Plan (WQMP) will be developed as part of the Construction SWPPP to be implemented from the onset of the construction to post construction. Biologically sensitive area protection will be established prior to construction and periodically monitored. Water quality protection during construction will be monitored based on a pre - construction Quality Assurance Project Plan (QAPP) and Sampling and Analysis Plan (SAP), to be developed prior to construction.

Maintenance is critical if stormwater wetland basins are to function as originally designed. A specific maintenance plan will be developed for the bioretention cell when the final design has been completed, outlining the schedule and scope of maintenance operations, as well as the documentation and reporting requirements. The following are general maintenance requirements: 1. The stormwater wetland basin should be inspected annually and inspections after major storm events are encouraged (wetland basin inspection and maintenance checklists will be developed specifically for the bioretention cell). Trash and debris should be removed as needed, but at least annually prior to the beginning of the wet season. 2. Site vegetation should be maintained as frequently as necessary to maintain the aesthetic appearance of the site and to prevent clogging of outlets, creation of dead volumes, and barriers to mosquito fish to access pooled areas, and as follows: Vegetation, large shrubs, or trees that limit access or interfere with basin operation should be pruned or removed. me • Slope areas that have become bare should be revegetated and eroded areas should be regraded prior to being revegetated. • Invasive vegetation, such as Alligatorweed (Alternanthera philoxeroides), Halogeton (Halogeton glomeratus), Spotted Knapweed (Centaurea maculosa), Giant Reed (Arundo donax), Castor Bean (Ricinus communis), Perennial Pepperweed (Lepidium latifolium), and Yellow Starthistle (Centaurea solstitalis) must be removed and replaced with noninvasive species. Invasive species should never contribute more than 25% of the vegetated area. • Dead vegetation should be removed if it exceeds 10% of area coverage. This does not include seasonal die -back where roots would grow back later in colder areas. Vegetation should be replaced immediately to maintain cover density and control erosion where soils are exposed. 3. Sediment buildup exceeding 6 inches over the storage capacity in the first cell should be removed. Sediments should be tested for toxic substance accumulation in compliance with current disposal requirements visual or olfactory indications of pollution are noticed. If toxic substances are encountered at concentrations exceeding thresholds of Title 22, Section 66261 of the California Code of Regulations, the sediment must be disposed of in a hazardous waste landfill. 4. Following sediment removal activities, replanting and/or reseeding of vegetation may be required for reestablishment. Routine maintenance will be performed to keep the bioretention cell piping, diversion piping, and seep water inlets clear of debris and sediments. Erosion control materials for embankment and slope protection will be inspected routinely and repaired or replaced, as necessary. Routine maintenance of the diversion structures and stilling pool will be required on a regular basis to keep them clear of sediment and debris accumulations. Upon initial installation, maintenance could occur as frequently as once per month, and could include a visual check, debris clearing, and/or equipment repair. Semiannual inspections for beginning and end of the wet season will be scheduled to identify any erosion problems and remove debris and sediment accumulation. A large rain event may require additional visual inspections to clear debris. The additional visual inspections may also require evaluation of wetland vegetation and inspection of vector presence or habitats on the project site. Inspections will include water quality BMPs at the storm outlets for erosion protection. Additionally, BMPs involving filtration functions will be inspected to ensure their pollutant reduction efficiency. Operation of the bioretention cell would be passive for the most part, requiring occasional inspections to confirm the treatment cells are operating as intended by the design. As a part of the proposed project, a comprehensive Operations and Maintenance Plan has be developed (see Appendix A). The Plan will be updated when the final design for the bioretention cell is complete.

AESTHETICS — Would the project: a) Have a substantial adverse effect on a scenic vista? b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? c) Substantially degrade the existing visual character or quality of the site and its surroundings? d) Create a new source of substantial light or glare which would adversely affect daytime or nighttime views in the area? Less Than Significant Potentially with Significant Mitigation Impact Incorporation Less Than Significant Impact No Impact Discussion a) Have a substantial adverse effect on a scenic vista? No Impact. A scenic vista is defined as a viewpoint that provides expansive views of a highly valued landscape for the benefit of the general public. According to the City of Newport Beach General Plan Update EIR, the City does not contain any officially designated scenic vistas; however, public view points are identified within the City. The nearest public view point is located about 1,200 feet west of the project site within the western portion of Big Canyon Park. This public view point provides views of Upper Newport Bay. Project grading and construction activities as well as restoration activities on the project site would not affect views from the nearest public view point because the view point offers views to the west toward Upper Newport Bay, and the project site is located east of the view point. Therefore, implementation of the proposed project would result in no impacts on scenic vistas. b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic building within a state scenic highway? No Impact. There are no officially designated scenic highways within Newport Beach (City of Newport Beach 2006). However, the project area is approximately one mile north of State Route 1 (Pacific Coast Highway), identified by the City as "Eligible for State Scenic Highway" designation. Because no scenic highways are currently designated within the City, implementation of the proposed project would result in no impact to scenic resources within a state- or locally designated scenic highway. 6-50 ❑ ❑ ® ❑ Discussion a) Have a substantial adverse effect on a scenic vista?

Less than Significant Impact. The construction activities associated with the project would result in changes to the existing visual character of the project site, including construction grading and the removal of existing vegetation. However, as mentioned above, the creek restoration and riparian habitat enhancement component of the project would remove the non-native vegetation and restore native vegetation on the project site. This component of the project would improve the existing visual character and quality of the site by restoring natural habitat conditions in the creek, and thus would result in a less than significant impact to the existing visual quality of the project site. d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? No Impact. The proposed project would create no new source of lighting in the project area, and thus would result in no light impacts. The project includes structural improvements to the culvert and stilling pond, however these features would use earth materials in their construction, and would result in no glare impacts. Thus, the project would result in no adverse effects to day or nighttime views in the area due to light or glare. Resources City of Newport Beach.

AGRICULTURAL AND FOREST RESOURCES — In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Department of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state's inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment project; and forest carbon measurement methodology provided in Forest Protocols adopted by the California Air Resources Board.

Discussion In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state's inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment project; and forest carbon measurement methodology provided in Forest Protocols adopted by the California Air Resources Board. 6-52 a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? No Impact. The project vicinity is located in a developed and urbanized area of the city. The project site is located on land designated as Urban and Built -Up Land, as shown on maps prepared pursuant to the Farmland Mapping and Monitoring Program (Department of Conservation 2012). Because the project site does not contain Farmland, the proposed project would not cause direct or indirect impacts related to the conversion of Prime Farmland, Unique Farmland, or Farmland of Statewide Importance. Thus, the project would result in no Farmland conversion impacts. b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? No Impact. A Williamson Act Contract requires private landowners to voluntarily restrict their land to agricultural land and compatible open -space uses. There is no Williamson Act contract in effect for the project site nor does the City have any agriculture -oriented zoning designations or Williamson Act Contract land. Because the project site does not have a Williamson Contract, the project would result in no zoning conflict or Williamson Act contract impacts. C) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Government Code section 51104(g))? No Impact. The project site is zoned as Open Space and is surrounded by lands zoned for residential and industrial uses. The City of Newport Beach does not contain any land zoned as forest land, timberland, or for timberland production. Therefore, the project would result in no forest land or timberland zoning impacts. d) Result in the loss of forest land or conversion of forest land to non -forest use? No Impact. The project site and surrounding area contain no forest land. Thus, implementation of the proposed project would result in no impacts related to the loss or conversion of forest land to non -forest use. e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use or conversion of forest land to non -forest use? No Impact. There are no agricultural uses or forest uses in the vicinity of the project site. Therefore, the proposed project would not involve changes in the existing environment that could result in conversion of Farmland to non-agricultural use or conversion of forest land to non -forest use. 6-53 Resources California Department of Conservation: Farmland Mapping and Monitoring Program.

AIR QUALITY — Where available, the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations. Would the project: a) Conflict with or obstruct implementation of the ❑ ❑ ® ❑ applicable air quality plan? b) Violate any air quality standard or contribute ❑ ❑ ® ❑ substantially to an existing or projected air quality violation? c) Result in a cumulatively considerable net increase of ❑ ❑ ® ❑ any criteria pollutant for which the project region is non -attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? d) Expose sensitive receptors to substantial pollutant ❑ ❑ ® ❑ concentrations? e) Create objectionable odors affecting a substantial ❑ ❑ ® ❑ number of people? Discussion a) Conflict with or obstruct implementation of the applicable air quality plan? Less than Significant Impact. A significant air quality impact may occur if a project is not consistent with the applicable Air Quality Management Plan (AQMP) or would in some way obstruct the implementation of the policies or obtainment of the goals of that plan. The proposed project is located within the City of Newport Beach, California. The city is located in the South Coast Air Basin (Basin), which is within the jurisdiction of the South Coast Air Quality Management District (SCAQMD). The SCAQMD is the agency principally responsible for comprehensive air pollution control in the Basin. To that end, the SCAQMD, a regional agency, works directly with the Southern California Association of Governments (SCAG), county transportation commissions, local governments, and cooperates actively with all state and federal government agencies. The SCAQMD develops rules and regulations, establishes permitting requirements, inspects emissions sources, and enforces such measures though educational programs or fines, when necessary. SCAQMD and SCAG are responsible for preparing the AQMP, which addresses federal and state Clean Air Act (CAA) requirements. Pursuant to these requirements, the SCAQMD is required to reduce emissions of criteria pollutants for which the Basin is in non -attainment. The AQMP details goals, policies, and programs for improving air quality in the Basin. The 2012 AQMP is currently the most recent plan for the Basin, and was adopted by the SCAQMD Governing Board on December 7, 2012. The 2012 AQMP was prepared to accommodate growth, to reduce the high levels of pollutants in the Basin, to meet federal and state air quality standards, and to minimize the fiscal impact that pollution control measures have on the local economy. It builds on the approaches taken from the previous 2007 AQMP and sets 6-55 forth a comprehensive and integrated program that will lead the Basin into compliance with the federal 24-hour PM2,5 air quality standard, and to provide an update to the Basin's commitments towards meeting the federal 8 -hour ozone standards. SCAG, which is the regional metropolitan planning organization for the Southern California area, has established the assumptions for growth, in terms of demographic growth and associated air quality impacts, and these assumptions are utilized in SCAQMD's AQMP. Since the forecasted growth in SCAQMD's AQMP for the Basin relies on SCAG's regional growth forecasts, and because SCAG's growth forecasts are based upon, among other things, land uses specified in city general plans, a project that is consistent with the land use designated in a city's general plan would also be consistent with the AQMP growth projections. As discussed in Chapter 2 (Project Description), the proposed project would improve water quality through water conservation, runoff reduction and restoration. Specifically, the proposed project would include a wetland that would treat both dry and wet weather flows in Big Canyon, and would eliminate the storm drain -associated vector habitat. The proposed project would contain a pump station, and a primary treatment structure. Given that the proposed project is an infrastructure project that serves only to treat contaminated water and improve the functionality of the wetland; implementation of the proposed project would not result in any additional population or housing growth in the project area that has not been accounted for in the City of Newport Beach General Plan. Consequently, as no growth -inducing development or land use would occur under the project, implementation of the project would not conflict with or obstruct the implementation of SCAQMD's AQMP. In addition, SCAQMD regional significance thresholds were designed to assist SCAQMD in determining if a project would worsen air quality conditions in the Basin. The determination of AQMP consistency is primarily concerned with the long-term influence of the proposed project on air quality in the Basin. As discussed under Question 3(b) below, the proposed project would not result in significant regional construction emissions and would not interfere with the attainment of air quality standards. Thus, the project's construction activities would not conflict with or obstruct implementation of the AQMP. Overall, the proposed project would result in a less than significant impact related to the AQMP. b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? Less than Significant Impact. A project may have a significant impact where project -related emissions would exceed federal, state, or regional standards or thresholds, or where project - related emissions would substantially contribute to an existing or projected air quality violation. As the proposed project consists of the installation of a surface water treatment system, culvert improvement and restoration activities, potential air quality impacts associated with the project would only occur during the construction phase as the operation of construction equipment would result in additional air emissions in the region. Once construction activities have been completed, operation of the proposed project would not involve any direct pollutant emissions sources onsite. In addition, vehicle emissions would be generated by worker trips to and from the project area for routine maintenance of the dosing station, including removal of sediment and debris from the stilling basin. These maintenance trips are anticipated to occur only once a month. As such, the 6-56 mobile emissions generated during project operations would be negligible as discussed below under Question 3(c). Construction of the proposed project is expected to last approximately five months and is tentatively scheduled to begin in September 2016 and continue through January 2017. Construction activities would commence with site preparation and clearance (approximately 2 weeks), followed by excavation and grading (approximately five weeks); culvert extension (6 weeks); dry weather diversion structures and external piping (2 weeks), construction of bioretention cell liner and piping (2 weeks), bioretention cell media placement (2 weeks), bioengineering structure construction (2 weeks), OCSD dosing station installation (6 weeks) and site vegetation restoration (4 weeks). Several of these activities will run concurrently to achieve the overall construction schedule of approximately five months. Criteria air pollutants are defined as pollutants for which the federal and state governments have established ambient air quality standards for outdoor concentrations to protect public health. These standards are designed to protect the most sensitive persons from illness or discomfort. Pollutants of concern include carbon monoxide (CO), nitrous oxides (NOx), particulate matter that is 10 microns or less in diameter and 2.5 microns or less in diameter (PMIo and PM2.5), sulfur oxides (SOx), and reactive organic gasses (ROG). Construction activities associated with the project involving site preparation and excavation would primarily generate respirable particulate matter (PMIo) emissions. Mobile source emissions (use of diesel -fueled equipment onsite, and traveling to and from the construction site) would primarily generate oxides of nitrogen (NOx) emissions. The amount of emissions generated on a daily basis would vary, depending on the amount and types of construction activities occurring at the same time. It is mandatory for all construction projects in the Basin to comply with SCAQMD Rule 403 (Fugitive Dust) for controlling fugitive dust emissions. Specific Rule 403 control requirements include, but are not limited to, applying water in sufficient quantities to prevent the generation of visible dust plumes, applying soil binders to uncovered areas, reestablishing ground cover as quickly as possible, and maintaining effective cover over exposed areas. Site watering and application of soil binders would reduce the particulate matter from becoming airborne, while washing of transport vehicle tires and undercarriages would reduce re -entrainment of construction dust onto the local roadway network. The analysis of daily construction emissions has been prepared utilizing the California Emissions Estimator Model (CalEEMod). CalEEMod was used to determine whether short-term construction -related emissions of criteria air pollutants associated with the proposed project would exceed SCAQMD's applicable regional thresholds and where mitigation would be required. Modeling was based on project -specific data, when available. Where project -specific information was not available, default model settings were used to estimate criteria air pollutant and ozone precursor emissions. For the purpose of this analysis, the construction emissions occurring on a peak (worst-case) day over the entire project construction period were estimated and evaluated against the applicable SCAQMD significance thresholds. The daily emissions that are estimated to occur on peak construction days for each construction phase of the proposed project are shown in Table 3-1. These calculations take into account that 6-57 appropriate dust control measures under SCAQMD Rule 403 would be implemented by the project during each phase of construction.

SOURCE: ESA, 2016 MOM As shown in Table 3-1 and Table 3-2, the peak daily regional emissions generated during project construction for individual phases, as well as those that overlap, would not exceed the SCAQMD daily significance thresholds for ROG, NOx, CO, SOX, PM2.5 and PMIo. Since construction emissions would not exceed the SCAQMD thresholds, the regional impacts related to air quality during project construction activities would be less than significant. C) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non -attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? Less than Significant Impact. With respect to air quality, a significant impact may occur if the project would add a considerable cumulative contribution to federal or state non -attainment pollutants. Because the Basin is currently classified as a state nonattainment area for ozone, PMIo, and PM2_5, cumulative development consisting of the proposed project along with other reasonably foreseeable future projects in the Basin as a whole could violate an air quality standard or contribute to an existing or projected air quality violation. With respect to determining the significance of the proposed project's contribution to regional emissions, the SCAQMD neither recommends quantified analyses of cumulative construction emissions nor provides methodologies or thresholds of significance to be used to assess cumulative construction impacts. Instead, the SCAQMD recommends that a project's potential contribution to cumulative impacts should be assessed utilizing the same significance criteria as those for project specific impacts. Furthermore, SCAQMD states that if an individual development project generates less than significant construction or operational emissions then the development project would not generate a cumulatively considerable increase in emissions for those pollutants for which the Basin is in nonattainment. As discussed under Question 3(b) above, the proposed project would not generate construction emissions that would exceed the SCAQMD's recommended thresholds. Once construction activities have been completed, operation of the proposed project would not involve any direct pollutant emissions sources onsite. In addition, because mobile emissions generated from worker trips to and from the project area for routine maintenance of the treatment structures are anticipated to only occur once a month, the mobile emissions generated would be negligible. As such, project operations would not generate substantial pollutant emissions that would exceed SCAQMD's applicable regional thresholds. Therefore, the proposed project would not generate a cumulatively considerable increase in emissions of the pollutants for which the Basin is in nonattainment, and impacts would be less than significant. d) Expose sensitive receptors to substantial pollutant concentrations? Less than Significant Impact. A significant impact may occur if a project were to generate pollutant concentrations to a degree that would significantly affect sensitive receptors. Sensitive receptors are populations that are more susceptible to the effects of air pollution than are the population at large. The SCAQMD identifies the following as sensitive receptors: long-term health care facilities, rehabilitation centers, convalescent centers, retirement homes, residences, •• 1 schools, playgrounds, child care centers, and athletic facilities. The nearest and most notable off- site sensitive receptors to the project would be the existing residential uses located approximately 46 feet northeast of the project site. Localized Construction Emissions Emissions from construction activities have the potential to generate localized emissions that may expose sensitive receptors to harmful pollutant concentrations. The SCAQMD has developed localized significance thresholds (LSTs) that are based on the amount of pounds of emissions per day that can be generated by a project that would cause or contribute to adverse localized air quality impacts. These localized thresholds, which are found in the mass rate look -up tables in the Final Localized Significance Threshold Methodology document prepared by the SCAQMD, apply to projects that are less than or equal to five acres in size and are only applicable to a project's on- site emissions for the following criteria pollutants: NOx, CO, PMIo, and PM2.5. LSTs represent the maximum emissions from a project that are not expected to cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standards, and are developed based on the ambient concentrations of that pollutant for each source receptor area (SRA) within the Basin. The project area, which consists of an approximately 5 acres, is located in the City of Newport Beach (SRA 18). The LSTs developed by SCAQMD are provided for the following distances from the source of emissions: 25 meters, 50 meters, 100 meters, 200 meters, and 500 meters. Additionally, the LSTs at these distances also vary based on the size of the project site. The SCAQMD has provided LSTs for sites that are 1 -acre, 2 -acre, and 5 -acre in size. As the total construction work area would be approximately 5 acres, the LSTs for a five -acre site is used for this analysis. The nearest and most notable off-site sensitive receptors that could potentially be subject to localized air quality impacts associated with construction of the proposed project would be the existing residential uses located approximately 45 feet northeast of the project site. Given the proximity of these sensitive uses to the construction areas where the surface water treatment system would be installed, the LSTs for a five -acre site with receptors located within 25 meters (82.02 feet) are used to address the potential localized air quality impacts associated with the project's construction -related NOx, CO, PMIo, and PM2.5 emissions.I As discussed in Question 3(b) above, it was determined that a worst-case construction day for the proposed project would include emissions from the entire 5 -acre construction site. However, whereas the construction emissions analysis conducted under Question 3(b) pertained to the project's total daily mass emissions, the LST analysis is concerned with a project's localized air quality impacts. The peak daily emissions generated during construction activities were estimated using CaIEEMod and are shown in Table 3-3. As LSTs are only concerned with a project's on-site 1 Although the existing sensitive uses (i.e., residential uses) located northeast of the project site would be located closer than 25 meters from the project's construction areas, the SCAQMD's LST methodology indicates that projects with boundaries located closer than 25 meters to the nearest receptor should use the LSTs for receptors located at 25 meters. 6-61 emissions, the emissions shown in Table 3-4 account for off-road equipment operating and fugitive dust. Table 3-4 shows the off-road equipment operating and fugitive dust emissions from those construction activities that will overlap.

No No No No See Appendix B for CalEEMod output. r*M As shown in Tables 3-3 and 3-4, the peak daily emissions generated during project construction activities would not exceed the applicable construction LSTs. Therefore, localized air quality impacts from the project's construction activities on the surrounding off-site sensitive receptors would be less than significant. Localized Traffic -Related Emissions Construction of the proposed surface water treatment system is not anticipated to result in substantial air quality impacts to the public with respect to traffic congestion. The proposed project limits the construction trips to distinct roads. Haul trucks would access the site from the intersection of San Joaquin Road and Jamboree Road west on San Joaquin Road to Back Bay Drive, and then travel north on Back Bay Drive to the Big Canyon Trail maintenance road entrance. Trucks would follow the maintenance road east to the construction staging area. It is estimated that approximately 20 daily haul truck trips and up to 1,000 total haul truck trips for material deliveries would occur over the course of construction. No work is expected to occur within city streets. Overall, the proposed project would result in a less than significant impact related to localized, traffic -related pollutant concentrations during construction. Toxic Air Contaminants A substance is considered toxic if it has the potential to cause adverse health effects in humans. A toxic substance released into the air is considered a toxic air contaminant (TAC). TACs are identified by state and federal agencies based on a review of available scientific evidence. In the State of California, TACs are identified through a two-step process that was established in 1983 under the Toxic Air Contaminant Identification and Control Act. This two-step process of risk identification and risk management was designed to protect residents from the health effects of toxic substances in the air. Construction of the proposed project would result in short-term diesel exhaust emissions from off-road heavy-duty equipment. Diesel exhaust is considered a TAC. Construction would result in the generation of diesel exhaust emissions from the use of off-road diesel equipment required for site preparation and excavation, and other construction activities. The dose to which sensitive receptors are exposed is the primary factor used to determine health risk. Dose is a function of the concentration of a substance or substances in the environment and the extent of exposure that person has with the substance. Dose is positively correlated with time, meaning that a longer exposure period would result in a higher exposure level for the maximally exposed individual. Thus, the risks estimated for a maximally exposed individual are higher if a fixed exposure occurs over a longer period of time. According to the Office of Environmental Health Hazard Assessment (OEHHA), health risk assessments, which determine the exposure of sensitive receptors to toxic emissions, should be based on a 70 -year exposure period; however, such assessments should be limited to the period/duration of activities associated with the proposed project. Construction of the entire project would occur over approximately a five month period, and would be separated into 9 different phases. As such, the project's construction activities would not be permanently stationed at any one location but instead would occur at different locations depending on the phase. Thus, the duration of the proposed construction 6-63 activities at any one site would only constitute a small percentage of the total 70 -year exposure period. Thus, diesel particulates from construction activities would not be anticipated to result in the exposure of sensitive receptors to levels that exceed applicable standards, and impacts would be less than significant. e) Create objectionable odors affecting a substantial number of people? Less than Significant Impact. A significant impact may occur if objectionable odors occur which would adversely impact sensitive receptors. According to the SCAQMD CEQA Air Quality Handbook, land uses associated with odor complaints typically include agricultural uses, wastewater treatment plants, food processing plants, chemical plants, composting, refineries, landfills, dairies, and fiberglass molding. As the proposed project consists of the installation of infrastructure for the treatment of water and restoration of the surrounding area, the proposed project is not a type of use identified by the SCAQMD as being associated with odors. Thus, the proposed project would not result in objectionable odors during operations, and this impact would be less than significant. During construction of the proposed project, exhaust from equipment may produce discernible odors typical of most construction sites. Such odors would be a temporary source of nuisance to adjacent uses, but would not affect a substantial number of people. As odors associated with project construction would be temporary and intermittent in nature, the odors would not be considered to be a significant environmental impact. Therefore, impacts associated with objectionable odors would be less than significant.

Discussion The following evaluation is a summary of the findings provided in the Biological Resources Technical Report prepared by ESA in January 2016. This report is provided in Appendix C. a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? Less than Significant with Mitigation Incorporated. No plant or wildlife species listed as state or federally threatened, endangered, or candidate species was observed within the project area, and no US Fish and Wildlife Service (USFWS)-designated Critical Habitat occurs onsite. Therefore, the project would not affect state or federally listed species or USFWS Critical Habitat. low No species covered by the Orange County Central -Coastal Natural Community Conservation Plan/Habitat Conservation Plan (NCCP/HCP) were identified in the project area; therefore, the project would not affect species covered by the Orange County Central -Coastal NCCP/HCP. Three California Species of Special Concern were observed within the riparian forest habitat onsite, including yellow warbler, yellow -breasted chat, and Cooper's hawk. These species, as well as other bird species nesting in the riparian or adjacent upland habitat or in the ornamental trees just outside of the project boundary could be negatively affected by the project through temporary loss of habitat during invasive species removal, floodplain grading, replanting, and construction of water quality, infrastructure and recreational facilities. Indirect impacts from construction (e.g., noise and increased activity) could also affect nesting bird species during the breeding season by disrupting breeding behavior, resulting in nest abandonment and loss of productivity. These potential impacts to nesting birds and vegetation communities would be considered significant. Mitigation Measures BI0-1: Nesting Birds. Impacts to nesting birds would be avoided by conducting all grading and construction activities outside of the bird breeding season (February 1—August 15). If breeding season cannot be avoided, the following measures would be followed. a. During the avian breeding season, a qualified Project Biologist shall conduct a preconstruction avian nesting survey no more than 10 days prior to vegetation disturbance or site clearing. If grading or other construction activity begins in the non - breeding season and proceeds continuously into the breeding season, no surveys shall be required. However, if there is a break of 10 days or more in grading or construction activities during the breeding season, a new nesting bird survey shall be conducted before these activities begin again. b. The nest survey shall cover all reasonably potential nesting locations on and within 300 feet of the proposed construction activities areas. c. If an active nest is found during an avian nest survey, a qualified Project Biologist shall implement a 300 -foot minimum avoidance buffer for coastal California gnatcatcher, least Bell's vireo, and other passerine birds and a 500 -foot minimum avoidance buffer for all raptor species. Buffer distances for other species would be determined by the Project Biologist based on the species and its breeding or nesting requirements. The nest site area shall not be disturbed until the nest becomes inactive or the young have fledged. BI0-2: Vegetation Communities. The project would impact a total of 2.46 acres of southern riparian forest, and 0.50 acre of coastal sage scrub. These vegetation communities are both highly disturbed from a heavy infestation of non-native plants and compacted, saline soils. These low - quality habitats would be restored to provide habitats with much greater ecological function than the current conditions. A total of 2.46 acres of southern riparian forest would be mitigated onsite through substantial habitat restoration (2.03 acres), willow riparian forest habitat creation (0.25 • .. acre), and riparian habitat enhancement (0.64 acre). Impacts to coastal sage scrub would be mitigated onsite through restoration of 1.85 acres, which is 1.35 acres in excess of the required 1:1 ratio. Impacts to non-native grassland, disturbed areas, and ornamental vegetation do not require mitigation (Table 3-5).

SOURCE: ESA, 2016 Significance after Mitigation Less than Significant. Potential impacts to nesting birds and vegetation communities would be reduced to less than significant with implementation of Mitigation Measures 13I0-1 and 13I0-2 described above. b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? Less than Significant with Mitigation Incorporated. The proposed project would permanently impact a total of 1.42 acres due to the implementation of the proposed water quality and infrastructure components and proposed trails. A total of 2.03 acres would be temporarily impacted from the riparian habitat restoration component of the project. An additional 0.90 acres would be temporarily impacted from construction -related activities. The permanent impacts to sensitive vegetation consist of 0.43 acre of southern riparian forest and 0.26 acre of coastal sage scrub (Table 3-6). Additional permanent impacts include 0.63 acre of non-native grassland, 0.08 acre of disturbed habitat, and 0.03 acre of ornamental land cover. The temporary impacts associated with the riparian habitat restoration component consist of primarily (1.77 acres) low - quality southern riparian forest, but also include 0.14 acre of non-native grassland, 0.06 acre of low -quality coastal sage scrub, 0.02 acre of disturbed habitat, and 0.03 acre of ornamental land cover. Restoration of this area would result in much higher quality native willow forest habitat. 6-67 Note that some areas of the existing southern riparian forest are not considered jurisdictional by the Corps/RWCQB and/or CDFW; therefore, refer to Table 3-7, below for detailed impact acreages of jurisdictional resources. The temporary impacts associated with construction consist of 0.43 acre of non-native grassland, 0.26 acre of low -quality southern riparian forest, 0.18 acre of low -quality coastal sage scrub, and 0.03 are of disturbed habitat. These construction -related temporary impacts include the staging area adjacent to the existing access road on the southwestern portion of the project area, the staging area adjacent to Jamboree road (the 8 -foot centerline of this area would become a permanent trail after infrastructure construction has been completed, but the surrounding slopes would be revegetated), and the slopes surrounding the bioretention cell. These temporary construction impacts would be considered significant.

Significance after Mitigation With implementation of Mitigation Measure 13I0-2, a total of 2.46 acres of southern riparian forest would be mitigated onsite through substantial habitat restoration (2.03 acres), willow riparian forest habitat creation (0.25 acre), and riparian habitat enhancement (0.64 acre). Impacts to coastal sage scrub would be mitigated onsite through restoration of 1.85 acres, which is 1.35 acres in excess of the required 1:1 ratio. Impacts to sensitive vegetation communities would be less than significant after implementation of Mitigation Measure 13I0-2. C) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Less than Significant with Mitigation Incorporated. ..: Avoidance. Based upon previous project planning and input from the resource agencies, infrastructure design measures have been implemented to avoid sensitive habitat and species to the extent practicable. Limitations to avoid the sensitive habitat and species remain due to the presence of two sewer lines that run across the existing riparian habitat and parallel to Jamboree Road. The location of the bioretention cell was placed to not impact future maintenance of either line. The proposed maintenance road/hiking trail has been place outside the jurisdictional wetland limits and crossing of the creek would now occur over the proposed culvert extension, rather than through the middle of the creek, which was the original trail location identified in the previous planning effort. Because of creek degradation, both the mainflow creek bed incision and the invasion of exotic species, temporary impacts to the habitat as a result of restoration implementation are unavoidable. The resulting restored habitat, however, would provide superior ecological benefits. Permanent Impacts to Jurisdictional Waters & Wetlands. As a result of the water quality improvement and infrastructure components, the project would permanently impact Waters of the United States/State which are characterized as southern riparian forest habitat. Impacts to Waters of the Waters of the United States/State would result from the extension of the culvert into Big Canyon, installation of the stilling basin and rip -rap energy dissipater, the maintenance road and turnaround, and construction of the bioretention cell. Table 3-7, Permanent Impacts to Jurisdictional Areas, defines impact acreages per the regulating resource area. Note, CDFW riparian includes Corps/RWQCB acreage, and CCC wetlands include CDFW and Corps/RWQCB jurisdiction. Thus, maximum permanent jurisdictional impacts do not exceed 0.57 acre. TABLE 3-7 PERMANENT IMPACTS TO JURISDICTIONAL AREAS Habitat Types Jurisdictional Area Impacts (acres) Corps/RWQCB Wetlands Corps/RWQCB Non -Wetlands 0.24 CDFW Riparian 0.44 CCC Wetland 0.57 SOURCE: ESA, 2015 Temporary Impacts to Jurisdictional Waters & Wetlands. Temporary impacts to jurisdictional areas would occur from implementation of the riparian habitat restoration component of the project. This includes the floodplain restoration grading, construction of the vegetated soil lifts and willow brush matts, and exotic removal activities. Because of the extensive invasive species presence in both the understory and overstory vegetation, the majority of impacts are considered beneficial, in that they would result in improved riparian health. Note that if additional exotic species are found in areas during implementation, temporary disturbances areas may be slightly higher. ..% Combined Permanent and Temporary Impacts to Jurisdictional Waters & Wetlands. The permanent and temporary impacts to jurisdictional waters and wetlands identified above are considered significant. Mitigation Measures 13I0-3: Jurisdictional Wetlands. As stated previously, the project has been designed to avoid and minimize impacts to jurisdictional resources and high-quality habitat to the extent practicable. To mitigate for unavoidable permanent impacts to Waters of the United States/State, both habitat creation and enhancement activities would be conducted onsite, as summarized in Table 3-8. To offset for permanent losses to 0.24 acre of non -wetland waters of the United States (Corps/RWQCB), 0.44 acre of CDFW and 0.57 acre of CCC jurisdictional wetlands, the creation of 0.25 acre of new habitat is proposed directly to the southwest of the proposed bioretention cell. This would satisfy the federal mandate for no net loss of wetlands by the Corps. The deficit acreage (0.19 acre for CDFW and 0.33 acre for CCC) would be satisfied through the removal of non-native vegetation in adjacent riparian and seed source areas (i.e., riparian habitat enhancement). This would include removal of the Brazilian peppertrees both east of Jamboree Road and on the north slopes of the canyon west of Jamboree Road that are the primary source of invasive seeds for Big Canyon. In addition, understory invasives not mapped by Dudek, including pampas grass, periwinkle, and English ivy, are prevalent throughout the project area. These species would be removed as part of the enhancement activities. Approximately 0.64 acre of invasive removal of the 1.07 acres available would be considered mitigation for unavoidable permanent impacts. Enhancement activities are distinguished from the restoration activities proposed (not mitigation) in that restoration would require grading and extensive soil remediation to achieve full habitat functioning, and enhancement areas would not. Jurisdictional areas temporarily impacted as a result of construction of the water quality or infrastructure -related components of the project would be restored to native habitat at a 1:1 ratio. A full Habitat Restoration Plan describing the Big Canyon restoration as well as habitat mitigation activities would be submitted for review and approval as part of the environmental permitting process. 6-70 TABLE 3-8 MITIGATION FOR PERMANENT IMPACTS TO JURISDICTIONAL AREAS Permanent Impacts Habitat Types (acres) Mitigation for Jurisdictional Impacts Corps/RWQCB Non-Wetlands/CDFW 0.24 0.25 acre of riparian forest habitat Riparian/CCC Wetland creation (1:1 mitigation ratio)1 CDFW Riparian only 0.19 0.64 acre of habitat enhancement CCC Wetland only 0.33 (extensive invasive species removal) Fullfills Corps "no net loss" requirement.

A full Habitat Restoration Plan describing the Big Canyon restoration as well as habitat mitigation activities would be submitted for review and approval as part of the environmental permitting process. 6-70 Significance after Mitigation With implementation of Mitigation Measure BIO -3, impacts to jurisdictional wetlands would be reduced to less than significant through the restoration of native habitat at a 1:1 ratio. d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of wildlife nursery sites? Less than Significant with Mitigation Incorporated. The project could temporarily disrupt wildlife movement during construction of the infrastructure and water quality components as well as invasive species removal, floodplain grading, and planting in the riparian habitat restoration area. This temporary disruption to wildlife movement and potential impact on native wildlife nursery sites would be considered significant. Mitigation Measure Implementation of Mitigation Measure 13I0-2 is required. Significance after Mitigation With implementation of Mitigation Measure BIO -2, onsite habitat would be restored and would be a higher functioning habitat that can provide cover and forage for migrating wildlife. The potential impacts to wildlife movement and nursery sites would be reduced to less than significant. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? No Impact. The project would not conflict with the protection of biological resources under the City of Newport Beach Municipal Code, or the City's proposed LCP Coastal Land Use Plan (2015 revised submittal). The proposed project, while not currently included in the Orange County Central -Coastal NCCP/HCP, would be designated to meet Plan standards. The highly degraded riparian channel, floodplain, and native vegetation would be restored to better functioning riparian habitat; restoration of adjacent coastal sage scrub areas would provide higher -quality upland habitat for wildlife and wetland buffer function; and the water quality facilities would greatly improve the hydrology and water quality of the creek. Therefore, the project would not conflict with the provisions of any local policies or ordinances protecting biological resources or any NCCP/HCPs. f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? No Impact. The project would not conflict with the protection of biological resources under the City of Newport Beach Municipal Code, or the City's proposed LCP Coastal Land Use Plan (2015 revised submittal). The proposed project, while not currently included in the Orange 6-71 County Central -Coastal NCCP/HCP, would be designated to meet Plan standards. The highly degraded riparian channel, floodplain, and native vegetation would be restored to better functioning riparian habitat; restoration of adjacent coastal sage scrub areas would provide higher -quality upland habitat for wildlife and wetland buffer function; and the water quality facilities would greatly improve the hydrology and water quality of the creek. Therefore, the project would not conflict with the provisions of any local policies or ordinances protecting biological resources or any NCCP/HCPs.

This report contains confidential information and is not for public distribution. a) Cause a substantial adverse change in the significance of a historical resource as defined in 15064.5? Less than Significant with Mitigation Incorporated. No built resources, archaeological sites, or tribal cultural resources were identified in the project area as a result of the current study, which included archival research, pedestrian survey, a search of the Sacred Lands File at the Native American Heritage Commission, and Native American outreach. That said, numerous prehistoric archaeological sites do occur throughout the area. A records search at the South Central Coast Information Center (SCCIC) shows that 35 archaeological resources have been recorded in a 1 mile radius, and that 5 of these occur with 0.15 mile. While most of these occur on ridgetops and mesas above and outside the project area, Native American representatives and the Sacred Lands File search indicate that the area contains sensitive archaeological resources. Given this, and given the fact that the archaeological survey only addressed resources visible on the surface, and that certain heavily vegetated areas were not accessible for survey, there is a potential, though small, that earthmoving activity could impact buried archaeological resources. This potential impact on unknown archaeological resources would be considered significant. Mitigation Measures CR -1: Archaeological Monitoring. An archaeological monitor (working under the direct supervision of a Secretary of the Interior -qualified archaeologist [USDI 2008]) shall be retained to observe all ground -disturbing activities, including but not limited to brush clearance, vegetation removal, grubbing, grading, and excavation.

Discussion The following evaluation is a summary of the findings provided in the Cultural Resources Study prepared by ESA in January 2016. This report contains confidential information and is not for public distribution. a) Cause a substantial adverse change in the significance of a historical resource as defined in 15064.5?

This potential impact on unknown archaeological resources would be considered significant. Mitigation Measures CR -1: Archaeological Monitoring. An archaeological monitor (working under the direct supervision of a Secretary of the Interior -qualified archaeologist [USDI 2008]) shall be retained to observe all ground -disturbing activities, including but not limited to brush clearance, vegetation removal, grubbing, grading, and excavation. Prior to start of ground -disturbing activities, the archaeologist shall conduct cultural resources sensitivity training for all construction personnel. Construction personnel shall be informed of the types of archaeological 6-73 resources that may be encountered, and of the proper procedures to be enacted in the event of an inadvertent discovery of archaeological resources or human remains. The City shall ensure that construction personnel are made available for and attend the training and retain documentation demonstrating attendance. Archaeological monitoring shall be conducted by an archaeologist familiar with the types of archaeological resources that could be encountered within the project site. The qualified archaeologist, in coordination with the City, may reduce or discontinue monitoring if it is determined that the possibility of encountering buried archaeological deposits is low based on observations of soil stratigraphy or other factors. The archaeological monitor shall be empowered to halt or redirect ground -disturbing activities away from the vicinity of a discovery until the qualified archaeologist has evaluated the discovery and determined appropriate treatment. The archaeological monitor shall keep daily logs detailing the types of activities and soils observed, and any discoveries. After monitoring has been completed, the qualified archaeologist shall prepare a monitoring report that details the results of monitoring. The report shall be submitted to the City, the Corps, and any Native American groups who request a copy. A copy of the final report shall be filed at the SCCIC. If archaeological resources are encountered during monitoring, and if it is determined that the discovered archaeological resource constitutes a historic property under Section 106 of the NHPA or a historical resource under CEQA, avoidance and preservation in place is the preferred manner of treatment. Preservation in place maintains the important relationship between artifacts and their archaeological context and also serves to avoid conflict with traditional and religious values of groups who may ascribe meaning to the resource. Preservation in place may be accomplished by, but is not limited to, avoidance, incorporating the resource into open space, capping, or deeding the site into a permanent conservation easement. In the event that preservation in place is demonstrated to be infeasible and data recovery through excavation is the only feasible mitigation available, a Cultural Resources Treatment Plan would be prepared and implemented by a qualified archaeologist in consultation with the Corps and the City. The plan will provide for the adequate recovery of the scientifically consequential information contained in the archaeological resource. The Corps and the City shall be required to consult with appropriate Native American representatives in determining treatment for prehistoric or Native American resources to ensure cultural values ascribed to the resource, beyond that which is scientifically important, are considered. CR -2: Native American Monitoring. The City shall retain a Native American monitor to observe all ground -disturbing activities, including but not limited to brush clearance, vegetation removal, grubbing, grading, and excavation. The Native American monitor shall be selected from amongst the Native American groups identified by the NAHC as having affiliation with the project area. The Native American representative shall be allowed to participate in the cultural resources sensitivity training, discusses in Mitigation Measure CR -1, and all authorities ascribed to the archaeological monitor, including the authority to stop work in the event of the discovery of cultural resources, shall also apply to the Native American monitor. In the event that 6-74 archaeological materials are encountered, the Native American monitor shall participate in any discussions involving treatment and subsequent mitigation. Significance after Mitigation With the implementation of Mitigation Measures CR -1 and CR -2, monitoring activities, as well as subsequent data recovery, if necessary, would reduce potential impacts on historical resources to less than significant. b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to 15064.5? Less than Significant with Mitigation Incorporated. As mentioned above, no archaeological resources were identified within the project area. That said, there is the potential to encounter buried resources during construction. This potential to encounter buried archaeological resources would be considered a significant impact. Mitigation Measures Implementation of Mitigation Measures CR -1 and CR -2 is required. Significance after Mitigation The implementation of Mitigation Measures CR -1 and CR -2 would ensure that the project would have a less than significant impact on unique archaeological resources. C) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Less than Significant with Mitigation Incorporated. The results of the paleontological records check at the Natural History Museum of Los Angeles County indicate that the project area is sensitive for paleontological resources. The Monterey Formation underlies younger Quaternary alluvium within the central portion of Big Canyon, and there are exposures of Monterey Formation in the Big Canyon walls. While grading operations will not involve substantial excavation extending into the underlying Monterey Formation within the canyon, or excavations in the exposures of Monterey Formation in the Big Canyon walls, there is a good chance of uncovering significant vertebrate fossil remains. Paleontological resources are considered part of the environment and a project that may directly or indirectly destroy a unique paleontological resource is a project that may have a significant effect on the environment. Therefore, the construction activities associated with the proposed project would result in potential significant impacts on paleontological resources. Mitigation Measures CR -3: Paleontological Monitoring. A qualified paleontologist meeting the Society for Vertebrate Paleontology (SVP) guidelines for professional paleontologist (SVP, 2010) shall be retained to oversee all mitigation measures related to paleontological resources. That said, both the paleontological and archaeological monitoring could be carried out by the same person, 6-75 presuming the monitor is qualified in both disciplines. During ground disturbing activity, the qualified paleontologist or paleontological monitor shall conduct spot-checks of exposed sediments. The purpose would be to determine whether the project would impact the paleontologically sensitive Monterey Formation. The qualified paleontologist may institute paleontological monitoring if, based on observations of subsurface stratigraphy or other factors, he or she determines that the possibility of encountering fossiliferous deposits is high. Paleontological monitoring would be conducted by a paleontological monitor working under the supervision of the qualified paleontologist. In the event that monitoring is required, the monitor shall have the authority to temporarily halt or divert work away from exposed fossils in order to recover the fossil specimens and shall complete daily monitoring logs outlining the day's activities. The qualified paleontologist shall prepare a final monitoring report to be submitted to the City and filed with the local repository, along with any fossils recovered during construction. The qualified paleontologist shall also contribute to any construction worker cultural resources sensitivity training (see Mitigation Measure CR -1) either in person or via a training module provided to the qualified archaeologist. The training shall include information of the types of paleontological resources that may be encountered, and the proper procedures to be enacted in the event of an inadvertent discovery of paleontological resources. In the event of unanticipated discovery of paleontological resources, the City shall cease ground - disturbing activities within 100 feet of the find until it can be assessed by the qualified paleontologist. The qualified paleontologist shall assess the find, implement recovery measures if necessary, and determine if paleontological monitoring is warranted once work resumes. Significance after Mitigation The implementation of Mitigation Measure CR -3 would ensure that the project would have a less than significant impact on paleontological resources or unique geologic features. d) Disturb any human remains, including those interred outside formal cemeteries? No Impact. No human remains were identified in the project area as a result of the archival research or survey, and it is anticipated that the project would have no impact on human remains. That said, the area was known to have been used by prehistoric Native Americans. In the unlikely event that human remains are uncovered during ground disturbing activities, appropriate state law would apply. Specifically, California Health and Safety Code Section 7050.5 requires that in the event human remains are discovered, the County Coroner be contacted to determine the nature of the remains. In the event the remains are determined to be Native American in origin, the Coroner is required to contact the NAHC within 24 hours to relinquish jurisdiction. Further, California PRC Section 5097.98, as amended by Assembly Bill 2641, provides procedures in the event human remains of Native American origin are discovered during project implementation. PRC Section 5097.98 requires that no further disturbances occur in the immediate vicinity of the discovery, that the discovery is adequately protected according to generally accepted cultural and archaeological standards, and that further activities take into 6-76 account the possibility of multiple burials. PRC Section 5097.98 further requires the NAHC, upon notification by a County Coroner, designate and notify a Most Likely Descendant (MLD) regarding the discovery of Native American human remains. Once the MLD has been granted access to the site by the landowner and inspected the discovery, the MLD then has 48 hours to provide recommendations to the landowner for the treatment of the human remains and any associated grave goods. In the event that no descendant is identified, or the descendant fails to make a recommendation for disposition, or if the land owner rejects the recommendation of the descendant, the landowner may, with appropriate dignity, reinter the remains and burial items on the property in a location that would not be subject to further disturbance.

(Refer to Division of Mines and Geology Special Publication 42.) No Impact. Based on a review of the City of Newport Beach General Plan, Safety Element, the City is located in the northern part of the Peninsular Ranges Province which is an area that is exposed to risks from multiple earthquake fault zones. The nearest earthquake that contains an Alquist-Priolo Earthquake Fault Zone is the Newport - Inglewood fault zone. This fault is located offshore from the City of Newport Beach. Based on a review of the Special Studies Zones map prepared by the California Division of Mines and Geology, there are no Alquist-Priolo Earthquake Fault Zones on the project Less Than Significant Potentially with Less Than Significant Mitigation Significant Issues (and Supporting Information Sources): Impact Incorporation Impact No Impact 6. GEOLOGY, SOILS, AND SEISMICITY — Would the project: a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? (Refer to Division of Mines and Geology Special Publication 42.) ii) Strong seismic ground shaking? iii) Seismic -related ground failure, including liquefaction? iv) Landslides? b) Result in substantial soil erosion or the loss of topsoil? c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse? d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial risks to life or property? e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? Discussion a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? (Refer to Division of Mines and Geology Special Publication 42.) No Impact. Based on a review of the City of Newport Beach General Plan, Safety Element, the City is located in the northern part of the Peninsular Ranges Province which is an area that is exposed to risks from multiple earthquake fault zones. The nearest earthquake that contains an Alquist-Priolo Earthquake Fault Zone is the Newport - Inglewood fault zone. This fault is located offshore from the City of Newport Beach. Based on a review of the Special Studies Zones map prepared by the California Division of Mines and Geology, there are no Alquist-Priolo Earthquake Fault Zones on the project site. Therefore, the proposed project would not be exposed to a rupture of a known earthquake fault. ii) Strong seismic ground shaking? Less than Significant Impact. The largest earthquake magnitude within a 100 -mile radius of the project site between 1800 and 2006 was 7.6 magnitude GSI 2006). The project site is subject to varying ground shaking intensities similar to other areas within the region. The City requires that all construction meet the latest standards of the California Building Code (CBC) which considers proximity to potential seismic sources and the maximum anticipated ground shaking possible. The construction of the proposed facilities on the project site would be in accordance with applicable City ordinances and policies and consistent with the most recent version of the CBC which requires structural design that can accommodate ground accelerations expected from known active faults. Compliance with the City's safety design standards as well as the CBC would reduce potential impacts associated with seismic ground shaking to less than significant. iii) Seismic -related ground failure, including liquefaction? Less than Significant Impact. Liquefaction is a secondary earthquake -induced hazard that occurs when water -saturated soils lose their strength and liquefy during intense and prolonged ground shaking. Based on a review of the Newport Beach General Plan, the project site includes areas that are susceptible to liquefaction. Adherence to the CBC and the City's Municipal Code requirements would implement proven geotechnical design measures that would minimize the potential for liquefaction, and potential impacts would be less than significant. iv) Landslides? Less than Significant Impact. Based on a review of the Newport Beach General Plan, the project site contains a few areas that could be susceptible to landslides. Project implementation would be required to adhere to the CBC and the City's Municipal Code to ensure the potential for landslides is reduce to less than significant. b) Result in substantial soil erosion or the loss of topsoil? Less than Significant Impact. During project construction, excavation and grading would be required. These activities would expose soil to erosive elements such as wind and rain. However, project construction would be required to comply with existing regulatory requirements that address soil erosion such as the National Pollutant Discharge Elimination System (NPDES) program. Any development site, such as the project site, that would disturb one or more acres would be required to develop and implement a Storm Water Pollution Prevention Plan (SWPPP) which includes the use of erosion control Best Management Practices to protect surface water and groundwater from the adverse effects of construction activities. 6-79 The erosion control best management practices (BMPs) such as scheduling, preservation of existing vegetation, hydroseeding, sandbags, fiber rolls, and silt fences would prevent the exposure of soil to wind and water and reduce the threat of erosion during construction to less than significant. Once constructed, the potential for erosion or loss of topsoil is substantially reduced. The project would include creek restoration activities that would include floodplain restoration, streambank stabilization and habitat restoration. Floodplain restoration and streambank stabilization activities would result in flood flow attenuation, stabilization of the north bank of the main channel, and creation of an active sinous riparian floodplain. The north creek bank at the inlet would be stabilized using natural bioengineering techniques. Riparian habitat would be restored directly downstream of the floodplain restoration area through the removal of invasive trees, soil remediation to reduce plant -limiting sodium levels, and replacement with native riparian species. The proposed project would reduce the potential for soil erosion or loss of topsoil to less than significant. C) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse? Less than Significant Impact. As described above, the development of the proposed structures would be required to adhere to the CBC and City requirements. These requirements would ensure that appropriate engineering techniques are implemented to reduce any potential for landslides, lateral spreading, subsidence, liquefaction or collapse to less than significant. d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial risks to life or property? Less than Significant Impact. Although the west side of Big Canyon contains previously dredged materials from Upper Newport Bay that could contain expansive soils, it is unknown if the project site contains expansive soil. As stated above, the proposed structures would be required to comply with the CBC and the City requirements for stable soils. Compliance with these requirements would reduce the potential impacts to less than significant. e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? No Impact. The proposed project does not include septic tanks or alternative waste disposal systems. As a result, there is no potential for soil failure associated with the installation of septic tanks or alternative waste disposal systems.

Discussion Gases that trap heat in the atmosphere are referred to as greenhouse gases (GHGs) because they capture heat radiated from the sun as it is reflected back into the atmosphere, much like a greenhouse does. The accumulation of GHGs has been implicated as a driving force for global climate change. Definitions of climate change vary between and across regulatory authorities and the scientific community, but in general can be described as the changing of the earth's climate caused by natural fluctuations and anthropogenic activities, which alter the composition of the global atmosphere. Prominent GHGs contributing to the greenhouse effect are carbon dioxide (CO2), methane (CHA nitrous oxide (N20), hydrofluorocarbons (HFCs), chlorofluorocarbons (CFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). Carbon dioxide is the "reference gas" for climate change, meaning that emissions of GHGs are typically reported in "carbon dioxide -equivalent" (CO2e) measures. There is international scientific consensus that human -caused increases in GHGs have and will continue to contribute to global warming, although there is uncertainty concerning the magnitude and rate of the warming. Potential global warming impacts in California may include, but are not limited to, loss in snow pack, sea level rise, more extreme heat days per year, more high ozone days, more large forest fires, and more drought years. Secondary effects are likely to include global rise in sea level, impacts to agriculture, changes in disease vectors, and changes in habitat and biodiversity. In 2005, in recognition of California's vulnerability to the effects of climate change, Governor Schwarzenegger established Executive Order S-3-05, which sets forth a series of target dates by which statewide emissions of GHG would be progressively reduced, as follows: • By 2010, reduce GHG emissions to 2000 levels; • By 2020, reduce GHG emissions to 1990 levels; and • By 2050, reduce GHG emissions to 80 percent below 1990 levels. In 2006, California passed the California Global Warming Solutions Act of 2006 (Assembly Bill No. 32; California Health and Safety Code Division 25.5, Sections 38500, et seq., or AB 32), which requires CARB to design and implement emission limits, regulations, and other measures, 6-82 Less Than Significant Potentially with Less Than Significant Mitigation Significant Issues (and Supporting Information Sources): Impact Incorporation Impact No Impact 7. GREENHOUSE GAS EMISSIONS — Would the project: a) Generate greenhouse gas emissions, either directly or El indirectly, that may have a significant impact on the environment? b) Conflict with an applicable plan, policy or regulation El El El adopted for the purpose of reducing the emissions of greenhouse gases?

On March 18, 2010, the California Office of Planning and Research (OPR) submitted amendments to the CEQA Guidelines for GHG emissions, as required by Public Resources Code section 21083.05. These CEQA Guideline amendments provide guidance to public agencies regarding the analysis and mitigation of the effects of GHG emissions in draft CEQA documents. The amendments are relatively modest changes to various portions of the existing CEQA Guidelines. a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? Less than Significant Impact. The proposed project would primarily contribute to global climate change as a result of emissions of GHGs, primarily CO2, emitted during construction activities associated with the installation of a surface water treatment system, including a pump station and culvert improvements. Once construction activities have been completed, operation of the proposed project would only generate minimal GHG emissions sources from vehicle emissions associated with worker trips to and from the project area for routine maintenance of the surface water treatment structure. However, because these trips would only occur once a month, these GHG emissions would be negligible. GHG impacts are considered to be exclusively cumulative impacts (CAPCOA, 2008); there are no non -cumulative GHG emission impacts from a climate change perspective. Thus, the purpose of this GHG analysis is to determine whether the contribution of GHG emissions by the proposed project would be cumulatively considerable. The City of Newport Beach has not adopted any significance criteria or guidelines for GHG analysis. SCAQMD has issued proposed standards and guidelines, proposing a 10,000 metric ton per year (MT/year) CO2e threshold for industrial projects for which it is the lead agency. Additionally, SCAQMD has proposed, a 3,000 MT/year CO2e threshold for residential and commercial developments (SCAQMD, 2008). For the purpose of this analysis, the project's total annual GHG emissions resulting from construction activities have been quantified and evaluated against the 3,000 MT/year CO2e screening criteria. As was conducted for the proposed project's air quality analysis in Question 3 (Air Quality), the project's construction -related GHG emissions were estimated for equipment exhaust, truck trips, and worker commute trips using CalEEMod. The project's estimated annual GHG emissions during construction are shown in Table 3-9. With respect to construction GHG emissions, SCAQMD recommends that the total emissions for a project be amortized over a 30 -year period and added to its operational emission estimates (SCAQMD, 2008). To determine the total construction emissions that would be generated from the project's surface water treatment system, the annual GHG emissions under a worst-case construction scenario was taken to conservatively represent the total emissions that would be generated from construction of the proposed project. Total construction -related GHG emissions was calculated to be 103.97 CO2e MT/yr. Amortized over 30 years, the proposed project 6-83 construction -related GHG emissions would be 3.47 COze MT/yr. With respect to operational emissions, the only GHG emissions generated by the proposed project would be periodic maintenance on-site. This maintenance would include maintenance of the water dosing station, monitoring the bioretention cell for any debris buildup and maintenance of any invasive or dead vegetation removal. The periodic maintenance would not be expected to result in higher GHG emissions than produced by construction activities. Therefore, a conservative estimate of the operational GHG emissions was chosen as 20% of the annual construction GHG emissions.

No NOTES: COze= carbon dioxide equivalent; MT/yr = metric tons per year; see Appendix B for CalEEMod model outputs. a The total project construction GHG emissions were derived by summing the annual construction emissions (MT/yr) for all nine phases. Total project construction GHG emissions = 103.97 COZe MT/yr. Amortized over 30 years, annual project construction GHG emissions = 3.47 CO2e MT/yr. As shown in Table 3-9, the proposed project's total annual GHG emissions resulting from construction activities and project operation would be approximately 24.26 MT COZe per year. Thus, the project's total annual GHG emissions would not exceed the 3,000 MT of COze per year screening threshold recommended by SCAQMD. Therefore, the proposed project would not result in the generation of substantial levels of GHG emissions and would not result in emissions that would adversely affect the statewide attainment of GHG emission reduction goals of AB 32. This impact would be less than significant. b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? No Impact. The proposed project would generate temporary construction -related GHG emissions and minimal GHG emissions during operations. Because the proposed project only involves the installation of surface water treatment infrastructure, culvert improvements and restoration activities, implementation of the project would not result in, or induce, growth in the project area that has not been accounted for by the City of Newport Beach. Consequently, no growth -inducing development or land use that would generate GHG emissions would occur under the project. The proposed project would not conflict with any adopted plan's goals of reducing GHG emissions. Overall, implementation of the proposed project would not conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of GHGs. Therefore, this impact would be less than significant.

HAZARDS AND HAZARDOUS MATERIALS — ❑ ❑ ❑ Would the project: a) Create a significant hazard to the public or the environment through the routine transport, use, or ❑ ❑ ❑ disposal of hazardous materials? b) Create a significant hazard to the public or the ❑ environment through reasonably foreseeable upset ❑ ❑ ❑ and accident conditions involving the release of hazardous materials into the environment? c) Emit hazardous emissions or handle hazardous or ❑ ❑ acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? d) Be located on a site which is included on a list of ❑ ❑ ❑ ❑ hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? e) For a project located within an airport land use plan ❑ ❑ ❑ or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? f) For a project within the vicinity of a private airstrip, ❑ ❑ ❑ would the project result in a safety hazard for people residing or working in the project area? g) Impair implementation of or physically interfere with ❑ ❑ ❑ an adopted emergency response plan or emergency evacuation plan? h) Expose people or structures to a significant risk of loss, ❑ ❑ ❑ injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? Discussion a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? Less than Significant Impact. Construction activities associated with the proposed project would involve site clearing, excavation, grading, and other ground -disturbing activities. Construction activities would be required for the installation of the project facilities, including the culvert extension, the bioretention cell liner and piping, and the bioengineering structure construction. Construction activities would occur for approximately five months within the project site. The proposed construction activities would require the use of equipment, such as loaders, excavators, trucks, and other powered equipment, and would therefore use fuels (gasoline or diesel) and lubricants (oils and greases). All construction equipment would be housed within the staging area of the project site. The construction equipment on site may require minor maintenance during construction activities, which may result in the disposal of hazardous byproducts from the equipment. Operation of the proposed facilities would involve the routine and major maintenance of the wetland basin. This would include the removal of trash, debris, and dying vegetation that interfere with facility maintenance. Maintenance activities would also include removal of any visual contamination from floatables, such as oil and grease, and repairs to any flow control structures as needed to maintain full functionality. Operational activities would involve limited amounts of hazardous materials used in and transported to the project site. The use of hazardous materials and substances during construction and operation activities would be subject to federal, state, and local health and safety requirements for handling, storage, and disposal. Therefore, hazardous material impacts related to construction activities would be less than significant. b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? Less than Significant Impact. As discussed above in discussion 3.8(a), limited quantities of hazardous materials such as gasoline, diesel, oils, and lubricants may be required to operate the construction equipment. Construction activities would be short-term, and the use of these materials would cease once construction is complete. The hazardous substances used during construction would be required to comply with existing federal, state and local regulations regarding the use and disposal of these materials. In the event of an accidental release during construction, containment and clean up would be in accordance with existing applicable regulatory requirements. Project operation would involve minimal transport and use of hazardous materials onsite. The use of hazardous materials and substances during construction and operation activities would be subject to federal, state, and local health and safety requirements for handling, storage, and disposal. Potential impacts to the public or the environment related to reasonably foreseeable accident conditions involving hazardous materials would be less than significant. C) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? Less than Significant Impact. The nearest existing school to the project site is Our Lady Queen of Angels High School located approximately 0. 16 miles north of the project site. In addition, Corona Del Mar High School is located approximately 0.25 miles north of the project site. Therefore, there are two schools within one-quarter mile of the proposed project area. Construction within the project site would include the use of loaders, dozers, haul trucks, compactors, and water trucks. Hazardous materials, such as oil, solvents, and gasoline, needed for the maintenance of the construction equipment would be used only in small quantities on the project site, and the use of hazardous substances would be compliant with City code regulations and Best Management Practices. Hazardous materials would not be transported on a routine basis. Construction activities are to last approximately five months; therefore, construction -related hazardous materials would be only temporarily present on site and subsequently removed after 6-87 construction is completed. Operation of the proposed project would not introduce any hazardous emissions or materials into the project site. Therefore, the proposed project would result in less than significant hazardous material -related impacts to schools within a quarter -mile of the project. d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? No Impact. Pursuant to Government Code 65962.5, environmental regulatory database lists were reviewed to identify and locate properties with known hazardous substance contamination within the proposed project area (California Government Code, Section 65960 et seq.) (see Appendix D). A review of the Department of Toxic Substances Control's (DTSC) Hazardous Waste and Substances List — Site Cleanup (Cortese List) indicates that identified hazardous material sites are not located within the project area (DTSC, 2007). There was a formerly leaking underground storage tank across the street at Big Canyon Country Club, but the case has closed as of May 15, 2001 (EDR, 2016). A review of the DTSC EnviroStor and the State Water Resources Control Board GeoTracker online databases did not indicate any open cleanup sites or hazardous waste facilities within the vicinity of the project area. Therefore, since the project is not located on a list associated with hazardous materials, no impacts would occur. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? No Impact. The nearest public airport to the project site is John Wayne Airport (JWA), approximately 2.5 miles north of the site. The John Wayne Airport Safety Compatibility Zones are defined in the Airport Environs Land Use Plan for JWA (ALUC, 2013). The proposed project is not located within any Safety Compatibility Zones for JWA. No impacts to safety hazards for people residing or working in the project area would occur. f) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? No Impact. The proposed project is not located within the vicinity of a private airstrip. The nearest private airstrip to the project site is the L.A. Times Costa Mesa Heliport approximately 5 miles northwest of the project site (www.tollfreeairline.com). No airstrip related hazard impacts would occur. g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? No Impact. The Newport Beach Fire Department prepared an Emergency Operations Plan (EOP) that was adopted by the City of Newport Beach in September 2011. The purpose of the EOP is to provide guidance for the City's response to extraordinary emergency situations associated with natural disasters, technological incidents, and national security emergencies in or affecting the .:: City of Newport Beach. The EOP also shows the City's emergency evacuation routes in the event of a tsunami. The project site is located along Jamboree Road, a designated emergency evacuation route. The proposed project would be constructed completely within the proposed project boundary. Construction equipment as well as haul trucks would access the site from Jamboree Road, and then travel west at the intersection of San Joaquin Road and Jamboree Road onto San Joaquin Road. Construction vehicles would travel to Back Bay Drive, and then travel north on Back Bay Drive to the Big Canyon Trail maintenance road entrance. Construction vehicles would follow the maintenance road east to the construction staging area. There would be no road closures or alterations to Jamboree Road during construction and all construction equipment would be stored in active grading areas and/or the proposed staging areas within the project area. Once constructed, the proposed project does not include any uses or design features that would result in interference with any adopted emergency response plan or emergency evacuation plan. The design of the proposed project would provide adequate emergency access consistent with City requirements, including public access trails within the project site. Therefore, the proposed project would not result in impacts to emergency access during construction and/or operation. The proposed project would not impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan and, thus, the project would result in no impact. h) Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? No Impact. The project site is not located in an area classified as a "Wildland Area That May Contain Substantial Forest Fire Risks and Hazards" or a "Very High Fire Hazard Severity Zone" by the California Department of Forestry and Fire Protection (CAL FIRE 2011). Therefore, the risk for wildland fire hazards is low, and project implementation would result in no impact to people or structures to a significant fire risk.

HYDROLOGY AND WATER QUALITY — Would the project: a) Violate any water quality standards or waste El El El requirements? b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the ❑ 1:1production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? c) Substantially alter the existing drainage pattern of a site or area through the alteration of the course of a stream or river, or by other means, in a manner that ❑ ❑ would result in substantial erosion or siltation on- or off-site? d) Substantially alter the existing drainage pattern of a site or area through the alteration of the course of a stream or river, or by other means, substantially increase the ❑ ❑ rate or amount of surface runoff in a manner that would result in flooding on- or off-site? e) Create or contribute runoff water which would exceed the capacity of existing or planned stormwater ❑ ❑ ❑ drainage systems or provide substantial additional sources of polluted runoff? f) Otherwise substantially degrade water quality? ❑ ❑ ❑ g) Place housing within a 100 -year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood ❑ ❑ ❑ Insurance Rate Map or other flood hazard delineation map? h) Place within a 100 -year flood hazard area structures ❑ ❑ that would impede or redirect flood flows? i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including ❑ ❑ ❑ flooding as a result of the failure of a levee or dam? j) Expose people or structures to a significant risk of loss, injury or death involving inundation by seiche, ❑ ❑ ❑ tsunami, or mudflow? Discussion a) Violate any water quality standards or waste discharge requirements? No Impact No Impact. The proposed project would not violate any water quality standards or waste discharge requirements because the project includes treatment facilities that would improve surface water quality in the project area. b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre- existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? Less than Significant Impact. Groundwater would be not required for construction or operation of the proposed project. Surface seeps along the creek bank immediately upstream and downstream of the culvert under Jamboree Road would be collected and diverted to the sanitary sewer due to the high selenium concentrations measured in these seeps. The collection and diversion of the significant source of selenium to the creek would measurably reduce downstream selenium concentrations and improve water quality through the creek segment that runs through the Big Canyon Preserve. This would allow for successful restoration efforts associated with the proposed project The estimated seepage flows are anticipated to be less than 10% of the total current dry weather flows in Big Canyon Creek. Therefore, approximately 90% of the current dry weather flows would be returned to the creek. Diverting the high selenium seepage flows would substantially reduce in -stream selenium concentrations in the downstream creek flowing through the restoration area. Because the project would not require the use of groundwater and the project would divert the current high selenium from seepage flows, the project would result in less than significant impacts on groundwater supplies. C) Substantially alter the existing drainage pattern of area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site? Less than Significant Impact. The project includes creek restoration activities that would include floodplain restoration, streambank stabilization and habitat restoration. Floodplain restoration and streambank stabilization activities would result in flood flow attenuation, stabilization of the north bank of the main channel, and creation of an active sinous riparian floodplain. The north creek bank at the inlet would be stabilized using natural bioengineering techniques. Riparian habitat would be restored directly downstream of the floodplain restoration area through the removal of invasive trees, soil remediation to reduce plant -limiting sodium levels, and replacement with native riparian species. The proposed project would reduce the potential for erosion and siltation to less than significant. d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on - or off-site? Less than Significant Impact. The additional impervious surfaces or other similar features are not substantial to cause any noticeable increase in surface runoff. Furthermore, the project includes the construction of a water quality treatment bioretention cell that would treat wet - weather flows from Jamboree Road. In order to treating the pollutants, stormwater flows from Jamboree that currently discharge directly into the riparian creek corridor, would be directed to 6-91 the bioretention cell that would retain and filter these flows. Following treatment of the stormwater, the flow would be discharged through an outlet structure that would control the rate of discharge. Therefore peak storm flows that can impact downstream sections of the creek would be attenuated. The proposed project would therefore reduce peak flows that may impact the sensitive habitat of the site, and potential flooding impacts associated with the project would be less than significant. e) Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? No Impact. Surface flow rates that currently discharge to the site from Jamboree Road would be measurably reduced by the bioretention cell. The project includes a new permanent access that would include adequately design stormwater drainage features to accommodate the proposed flows and not impact downstream areas. In addition, the project would not add additional sources of polluted runoff, but would improve downstream surface water quality through the implementation of the proposed surface water quality improvements. The proposed project would result in no impacts to the capacity of the existing stormwater drainage system and no impacts to downstream surface water quality. f) Otherwise substantially degrade water quality? No Impact. The Project would result in positive water quality improvement for both stormwater and dry weather surface flows. Storm Flows — The purpose of the stormwater treatment system is to reduce transportation - related constituent concentrations currently discharged to Big Canyon Creek during storm events and to attenuate stormwater peak -flow discharge rates from the contributing Jamboree Road drainage area. The transportation -related pollutants are currently conveyed to the receiving waters in Big Canyon Creek from a variety of sources, including vehicles, road maintenance, maintenance facility runoff, and landscaping maintenance. Vehicles are known to produce a variety of pollutants that can have a negative impact on water quality in the receiving waters to which they drain. Metals such as copper and zinc can build up on road surfaces through brake and tire wear; other metals such as cadmium, chromium and sometimes lead can be deposited on road surfaces from paint on vehicles and streets. Metals often bind to sediments, trash, and debris on road surfaces; these can be carried into waterways during storm events. In addition to pollutants associated with vehicles, landscaped areas associated with or adjacent to streets (e.g., median, parkway, and residential landscaping) can be sources of pollutants such as pesticides, nutrients (particularly nitrate and phosphorus), and fecal -indicator bacteria (all of which are known to be associated with urban landscaping, which is found throughout the 11.1 -acre Jamboree Road drainage area). These pollutants can be transported to receiving waters during storm events. Finally, in addition to direct deposition to the road surface, street surfaces and adjacent walkways and landscaped areas can be impacted from vehicle emissions through atmospheric deposition of pollutants such as the dissolved fraction of metals and organics (e.g., polynuclear aromatic hydrocarbons (PAHs). 6-92 According to national and regional best management practices (BMPs) manuals (e.g., the California Stormwater Quality Association BMP handbook), the technology proposed in the stormwater treatment system has been shown to be effective in treating a variety of pollutants associated with transportation runoff, including trash, sediment (and attached pollutants), nutrients and organics such as PAHs and pesticides, and fecal -indicator bacteria. The stormwater treatment system would consist of a primary stormwater treatment structure and a bioretention cell, as described below. Dry Weather Flows The purpose of the dry weather flow diversion is to limit the contact between dry weather flows with low selenium concentrations with groundwater seepage flows that contain much higher selenium concentrations. Surface seeps would be passively collected and diverted to the sanitary sewer. The lower concentration dry weather flows would be diverted around the higher selenium seeps and back into the creek channel. Selenium reductions of 70- 90% are anticipated in downstream flows. These reductions would allow for successful and sustainable restoration of the creek as part of the proposed project and in potential future downstream restoration efforts. Overview With the implementation of the proposed project, surface and groundwater quality would not be impacted. g) Place housing within a 100 -year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? No Impact. All residential properties are on the high banks above the 100 -year floodplain. These banks would not be impacted by the proposed project. h) Place within a 100 -year flood hazard area structures which would impede or redirect flood flows? Less than Significant Impact. One -Hundred year flows from Big Canyon Creek would be directed through the restored creek section and the downstream stream channels. This proposed project would improve surface water hydrology by reducing peak flows from Jamboree Road that would be directed through the proposed bioretention cell. The currently incised creek channel downstream of the culvert would be restored to include a wider floodplain and the northern bank stabilized using bio -engineering techniques. The extended culvert element to accommodate the new access road includes the implementation of concrete stilling basin and grade control structure to dissipate storm flows and reduce the potential for downstream erosion. The planned restoration would include removal of invasive plants and re -vegetation with native plants that would also improve overall hydrology. The implementation of the proposed facilities on the project site would result in less than significant impacts associated with a 100 -year flood hazard area. 6-93 i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? No Impact. No risk associated with property loss or life threatening conditions would result from the proposed project as no significant changes in site hydrology would occur as a result of the project. Hydraulic analysis of the proposed flood control conveyance show that velocities in the conveyance would be below erosive levels due to the 2% longitudinal slope and heavily vegetated side slopes. The proposed project would not increase the risk of people or structures to loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam. The watershed is heavily urbanized and the Upper Newport Bay is protected against ocean waves. Therefore, the proposed project would result in no impacts related to flooding. j) Expose people or structures to a significant risk of loss, injury or death involving inundation by seiche, tsunami, or mudflow? No Impact. No risk associated with property loss or life threatening conditions would result from the proposed project as no significant changes in site hydrology would occur as a result of the project. Hydraulic analysis of the proposed flood control conveyance show that velocities in the conveyance would be below erosive levels due to the 2% longitudinal slope and heavily vegetated side slopes. The proposed project would not increase the risk of the project area or surrounding land to be inundated as a result of seiche, tsunami, or mudflow. The watershed is heavily urbanized and the Upper Newport Bay is protected against ocean waves. Therefore, the proposed project would result in no impacts related to seiche, tsunami or mudflow.

LAND USE AND LAND USE PLANNING — Would the project: a) Physically divide an established community? b) Conflict with any applicable land use plan, policy, or ❑ regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? c) Conflict with any applicable habitat conservation plan ❑ ❑ ❑ or natural community conservation plan? Discussion a) Physically divide an established community? No Impact. The project site is located between two residential communities to the north and south of the project site. Creek restoration activities confined within the project site would enhance the vegetation and habitat of the creek, and would not physically divide the existing communities to the north and south. Thus, implementation of the project would result in no impacts to the physical division of an established community. b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? No Impact. The proposed project is consistent with the existing City of Newport Beach General Plan land use and zoning designations. The project site is zoned as Open Space (OS) within the City's General Plan, Zoning Ordinance, and Local Coastal Program (City of Newport Beach 2010). The OS land use and zoning designation is intended to provide areas for a range of public and private uses to "protect, maintain, and enhance the community's natural resources." Since the project aims to restore natural habitat and improve water quality in the creek, the project's objectives align with applicable land use plans regarding OS. The project will not conflict with any applicable land use plans, therefore, the project would result in no impacts to existing land use plans, policies or regulations. C) Conflict with any applicable habitat conservation plan or natural communities conservation plan? No Impact. The project would not conflict with the protection of biological resources under the City of Newport Beach Municipal Code, or the City's proposed LCP Coastal Land Use Plan (2015 revised submittal). The proposed project, while not currently included in the Orange County Central -Coastal NCCP/HCP, will be designated to meet Plan standards. The highly degraded riparian channel, floodplain, and native vegetation will be restored to better functioning riparian habitat; restoration of adjacent coastal sage scrub areas will provide higher -quality upland habitat for wildlife and wetland buffer function; and the water quality facilities will greatly improve the hydrology and water quality of the creek. Therefore, the project will not conflict with the provisions of any local policies or ordinances protecting biological resources or any NCCP/HCPs.

MINERAL RESOURCES — Would the project: a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? b) Result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan? Discussion a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the State? No Impact. Based on the guidelines adopted by the California Geological Survey (CGS), areas known as Mineral Resource Zones (MRZ) are classified according to the presence or absence of significant mineral resource deposits. The City is required to respond to mineral resource recovery areas that have been designated by the State as MRZ-2 (significant existing or likely mineral deposits). These classifications indicate the potential for a specific area to contain significant mineral resources. According to the CGS, the City of Newport Beach does not contain any land classified as MRZ-2. The project site is located on land classified as MRZ-1, which are "areas where adequate geologic information indicates that no significant mineral deposits are present, or where it is judged that little likelihood exists for their presence" (Division of Mines and Geology). The project involves restoration and revegetation of the creek, and no mining operations would occur. Therefore, the proposed project would result in no loss of availability of known mineral resources valuable to the region or residents of the State, and no impact would occur. b) Result in the loss of availability of a locally -important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan? No Impact. As discussed in the 3.11a), the lack of impacts to known mineral resources that would be of value to the region or residents of the State applies equally to locally important mineral resource recovery sites. The City of Newport Beach General Plan classifies no land with locally -important mineral resource deposits within the City.

Discussion Noise is generally defined as unwanted sound. Sound, traveling in the form of waves from a source, exerts a sound pressure level (referred to as sound level) that is measured in decibels (dB), which is the standard unit of sound amplitude measurement. The dB scale is a logarithmic scale that describes the physical intensity of the pressure vibrations that make up any sound, with 0 dB corresponding roughly to the threshold of human hearing and 120 to 140 dB corresponding to the threshold of pain. Pressure waves traveling through air exert a force registered by the human ear as sound. Sound pressure fluctuations can be measured in units of hertz (Hz), which correspond to the frequency of a particular sound. Typically, sound does not consist of a single frequency, but rather a broad band of frequencies varying in levels of magnitude. When all the audible frequencies of a sound are measured, a sound spectrum is plotted consisting of a range of frequency spanning 20 to 20,000 Hz. The sound pressure level, therefore, constitutes the additive force exerted by a sound corresponding to the sound frequency/sound power level spectrum. The typical human ear is not equally sensitive to all frequencies of the audible sound spectrum. As a consequence, when assessing potential noise impacts, sound is measured using an electronic filter that deemphasizes the frequencies below 1,000 Hz and above 5,000 Hz in a manner corresponding to the human ear's decreased sensitivity to extremely low and extremely high frequencies. This method of frequency weighting is referred to as A -weighting and is expressed Less Than Significant Potentially with Less Than Significant Mitigation Significant Issues (and Supporting Information Sources): Impact Incorporation Impact No Impact 12. NOISE —Would the project: a) Result in exposure of persons to, or generation of, El noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? b) Result in exposure of persons to, or generation of, ❑ excessive groundborne vibration or groundborne noise levels? c) Result in a substantial permanent increase in ambient ❑ noise levels in the project vicinity above levels existing without the project? d) Result in a substantial temporary or periodic increase ❑ ® ❑ in ambient noise levels in the project vicinity above levels existing without the project? e) For a project located within an airport land use plan ❑ ❑ area, or, where such a plan has not been adopted, in an area within two miles of a public airport or public use airport, would the project expose people residing or working in the area to excessive noise levels? f) For a project located in the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? Discussion Noise is generally defined as unwanted sound. Sound, traveling in the form of waves from a source, exerts a sound pressure level (referred to as sound level) that is measured in decibels (dB), which is the standard unit of sound amplitude measurement. The dB scale is a logarithmic scale that describes the physical intensity of the pressure vibrations that make up any sound, with 0 dB corresponding roughly to the threshold of human hearing and 120 to 140 dB corresponding to the threshold of pain. Pressure waves traveling through air exert a force registered by the human ear as sound. Sound pressure fluctuations can be measured in units of hertz (Hz), which correspond to the frequency of a particular sound. Typically, sound does not consist of a single frequency, but rather a broad band of frequencies varying in levels of magnitude. When all the audible frequencies of a sound are measured, a sound spectrum is plotted consisting of a range of frequency spanning 20 to 20,000 Hz. The sound pressure level, therefore, constitutes the additive force exerted by a sound corresponding to the sound frequency/sound power level spectrum. The typical human ear is not equally sensitive to all frequencies of the audible sound spectrum. As a consequence, when assessing potential noise impacts, sound is measured using an electronic filter that deemphasizes the frequencies below 1,000 Hz and above 5,000 Hz in a manner corresponding to the human ear's decreased sensitivity to extremely low and extremely high frequencies. This method of frequency weighting is referred to as A -weighting and is expressed in units of A -weighted decibels (dBA). A -weighting follows an international standard methodology of frequency deemphasis and is typically applied to community noise measurements. An individual's noise exposure is a measure of noise over a period of time. While a noise level is a measure of noise at a given instant in time, community noise varies continuously over a period of time with respect to the contributing sound sources of the community noise environment. Community noise is primarily the product of many distant noise sources, which constitute a relatively stable background noise exposure, with the individual contributors unidentifiable. The background noise level changes throughout a typical day, but does so gradually, corresponding with the addition and subtraction of distant noise sources such as traffic. What makes community noise variable throughout a day, besides the slowly changing background noise, is the addition of short -duration, single -event noise sources (e.g., aircraft flyovers, motor vehicles, sirens), which are readily identifiable to the individual. These successive additions of sound to the community noise environment change the community noise level from instant to instant, requiring the measurement of noise exposure over a period of time to legitimately characterize a community noise environment and evaluate cumulative noise impacts. This time -varying characteristic of environmental noise is described using statistical noise descriptors. The most frequently used noise descriptors are summarized below: Leq: The Leq, or equivalent sound level, is the energy -mean dBA during a measured time interval. It is the "equivalent" constant sound level that would have to be produced by a given source to equal the acoustic energy contained in the fluctuating sound level measured. Ln,.,,;: The maximum, instantaneous noise level experienced during a given period of time. L,,,;,,: The minimum, instantaneous noise level experienced during a given period of time. L&: Also termed the DNL, the Ldn is defined as the A -weighted average sound level for a 24- hour day with a 10 -dB penalty added to nighttime sound levels (10:00 p.m. to 7:00 a.m.) to compensate for increased sensitivity to noise during usually quieter evening and nighttime hours. CNEL: CNEL, or Community Noise Equivalent Level, is defined as the A -weighted average sound level for a 24-hour day. It is calculated by adding a 5 -dB penalty to sound levels in the evening (7:00 p.m. to 10:00 p.m.) and a 10 -dB penalty to sound levels at night (10:00 p.m. to 7:00 a.m.) to compensate for increased sensitivity during such time periods when a quiet environment is expected. An important way of predicting a human reaction to a new noise environment is the way it compares to the existing environment to which one has adapted (i.e., comparison to the ambient noise environment). In general, the more a new noise level exceeds the previously existing 6-100 ambient noise level, the less acceptable the new noise level would be judged by those hearing it. With regard to increases in A -weighted noise level, the following relationships generally occur: • Except in carefully controlled laboratory experiments, a change of 1 dBA cannot be perceived; • Outside of the laboratory, a 3 dBA change in noise levels is considered to be a barely perceivable difference; • A change in noise levels of 5 dBA is considered to be a readily perceivable difference; and • A change in noise levels of 10 dBA is subjectively heard as doubling of the perceived loudness. These relationships occur in part because of the logarithmic nature of sound and the decibel system. The human ear perceives sound in a non-linear fashion, hence the decibel scale was developed. Because the decibel scale is based on logarithms, two noise sources do not combine in a simple additive fashion, but rather logarithmically. For example, if two identical noise sources produce noise levels of 50 dBA, the combined sound level would be 53 dBA, not 100 dBA. Noise levels from a particular source generally decline as distance to the receptor increases. Other factors, such as the weather and reflecting or barriers, also help intensify or reduce the noise level at any given location. A commonly used rule of thumb for roadway noise is that for every doubling of distance from the source, the noise level is reduced by about 3 dBA at acoustically "hard" locations (i.e., the area between the noise source and the receptor is nearly complete asphalt, concrete, hard -packed soil, or other solid materials) and 4.5 dBA at acoustically "soft" locations (i.e., the area between the source and receptor is normal earth or has vegetation, including grass). Noise from stationary or point sources is reduced by about 6 to 7.5 dBA for every doubling of distance at acoustically hard and soft locations, respectively. Noise levels may also be reduced by intervening structures — generally, a single row of buildings between the receptor and the noise source reduces the noise level by about 5 dBA, while a solid wall or berm reduces noise levels by 5 to 10 dBA. Regulatory Framework It should be noted that the project does not include any permanent noise sources after the completion other than periodical maintenance. City of Newport Beach General Plan Policy N1.8 describes significant noise impacts as below: Require the employment of noise mitigation measures for existing sensitive uses when a significant noise impact is identified. A significant noise impact occurs when there is an increase in the ambient CNEL produced by new development impacting existing sensitive uses. The CNEL increase is shown in Table 1. 6-101 TABLE 3-10 GENELAN PLAN POLICY N1.8 DBA INCREASE Existing CNEL (dBA) dBA Increase 55 3 60 2 65 1 70 1 75+ Any increase is considered significant SOURCE: City of Newport Beach General Plan Policy N5.1 describes that the limited hours of construction activity is enforced. The limited construction hours are based on the municipal code. City of Newport Beach Municipal Code Section 10.28.040 limits construction hours between 7:00 a.m. and 6:30 p.m. on any weekdays and between 8:00 a.m. and 6:00 p.m. on any Saturdays. It also prohibits construction activities on any Sundays and any federal holidays. a) Exposure of persons to or generation of noise levelS in excess of standards established in the local general plan or noise ordinance, or applicable standards or other agencies? Less than Significant Impact. A significant impact may occur if the proposed project would generate excessive noise that exceeds the noise level standards set forth in the respective General Plan Noise Elements and Noise Ordinances of the City of Newport Beach. Potential project noise impacts were assessed for 1) project construction to the adjacent noise sensitive receivers, 2) off- site noise impacts due to the project operation, and 3) on-site noise impact to the project site. It is concluded the impact would be less than significant. See details below. Construction Noise With regard to construction noise, the City's noise ordinance, Section 10.28.040 limits construction hours between 7:00 a.m. and 6:30 p.m. on any weekdays and between 8:00 a.m. and 6:00 p.m. on any Saturdays. It also prohibits construction activities on any Sundays and any federal holidays. It is assumed that construction would not occur outside of indicated hours and considered less than significant. Off -Site Noise After the completion of the project, there would be no noise generated sources in the project site. The potential noise generated activities would be occasional maintenance and repair activities throughout a year. It is assumed that maintenance and repair activities would occur within the 6-102 hours indicated in the City's noise ordinance, Section 10.28.040. Therefore, the impact would be less than significant. On -Site Noise The project site is identified as )pen Space in the City's General Plan, and it would remain as Open Space after the completion of the project. The City's General Plan Noise Element Policy N1.8, describes the threshold of significant impact based on the increase of noise levels over the existing noise levels. Since the ambient noise in the vicinity of the project site would remain unchanged after the completion of the project, the impact would be less than significant. b) Exposure of people to generation or excessive groundborne vibration or groundborne noise levels? Less than Significant with Mitigation Incorporation. Ground -borne vibration would be generated from the operation of heavy construction equipment at the project site, which could potentially affect the existing sensitive land uses surrounding the site. Once completed, there would be no operational sources causing ground -borne vibration. The closest off-site structure to the project construction area is the multi -family residential structure to the north adjacent to Jamboree Road. The distance to this structure is approximately 10 feet from potential construction equipment. Ground -borne vibration levels resulting from construction activities at the project site were estimated using data published by the Federal Transit Administration (FTA) in its Transit Noise and Vibration Impact Assessment (2006) document. The FTA has adopted vibration standards that are used to evaluate potential building damage impacts related to construction activities, which are shown in Table 3-11. TABLE 3-11 CONSTRUCTION VIBRATION DAMAGE CRITERIA Building Category PPV (In/sec) I. Reinforced -concrete, steel or timber (no plaster) 0.5 II. Engineered concrete and masonry (no plaster) 0.3 III. Non -engineered timber and masonry buildings 0.2 IV. Buildings extremely susceptible to vibration damage 0.12 SOURCE: FTA, 2006. In addition, the FTA has also adopted standards associated with human annoyance for ground - borne vibration impacts for the following three land -use categories: Vibration Category 1 — High Sensitivity, Vibration Category 2 — Residential, and Vibration Category 3 — Institutional. The FTA defines Category 1 as buildings where vibration would interfere with operations within the building, including vibration -sensitive research and manufacturing facilities, hospitals with vibration -sensitive equipment, and university research operations. Vibration -sensitive equipment 6-103 includes, but is not limited to, electron microscopes, high-resolution lithographic equipment, and normal optical microscopes. Category 2 refers to all residential land uses and any buildings where people sleep, such as hotels and hospitals. Category 3 refers to institutional land uses such as schools, churches, other institutions, and quiet offices that do not have vibration -sensitive equipment, but still have the potential for activity interference. The vibration thresholds associated with human annoyance for these three land -use categories are shown in Table 3-12. TABLE 3-12 GROUNDBORNE VIBRATION IMPACT CRITERIA FOR GENERAL ASSESSMENT Occasional Land Use Category Frequent Events' Eventsb Infrequent Events' Category 1: Buildings where vibration would 65 VdB' 65 VdB' 65 VdB' interfere with interior operations. Category 2: Residences and buildings where people normally sleep. Category 3: Institutional land uses with primarily daytime use. 72 VdB 75 VdB 80 VdB 75 VdB 78 VdB 83 VdB a "Frequent Events" is defined as more than 70 vibration events of the same source per day. b "Occasional Events' is defined as between 30 and 70 vibration events of the same source per day. c 'Infrequent Events' is defined as fewer than 30 vibration events of the same kind per day. d This criterion is based on levels that are acceptable for most moderately sensitive equipment such as optical microscopes. SOURCE: FTA, 2006. The various peak particle velocity (PPV) expressed in inches per second (in/sec) and root mean square (RMS) velocity expressed in VdB levels for the general construction equipment that would operate during the construction of the proposed project are identified in Table 3-13. Note that it is assumed that impact activities, such as pile driving, would not be used for this project. TABLE 3-13 VIBRATION SOURCE LEVELS FOR CONSTRUCTION EQUIPMENT Equipment Approximate PPV Approximate RMS (in/sec) at 25 feet (VdB) at 25 feet Large Bulldozer 0.089 87 Loaded Trucks 0.076 86 Jackhammer 0.035 79 Small Bulldozer 0.003 58 Vibratory roller would be used only for Pond Lining/Miscellaneous phase. SOURCE: FTA, 2006. 6-104 Structure Damage Construction activities associated with the proposed project would have the potential to impact the surrounding off-site structures. The closest multi -family residential structure to the north is considered as non -engineered timber structure and is located approximately 10 feet from construction equipment. Therefore, the vibration impact threshold would be 0.2 in/sec PPV. The PPV value of a large bulldozer at 10 feet would be 0.352 in/sec PPV, which exceeds the impact threshold. This exceedance of the vibration level threshold for structural damage would be considered significant. Mitigation Measure N0I-1: Large construction equipment, such as large bulldozer and loaded trucks, shall be replaced with smaller equipment when the construction equipment is within 45 feet of the residential structure. Significance after Mitigation With the implementation of Mitigation Measure MM NOI-1, vibration impacts causing structural damage from construction activities would be less than significant. When a small bulldozer is used, the PPV value at 10 feet would be 0.119 in/sec PPV, which would be less than the impact threshold of 0.2 in/sec PPV. Human Annoyance The construction vibration could annoy people within a building. The vibration impact threshold for human annoyance at a residential structure would be 80 VdB. The RMS value of a large bulldozer at 10 feet would be 99 VdB which would exceed the human annoyance vibration threshold of 80 VdB. Therefore, the project construction activities could result in significant human annoyance vibration impacts. Mitigation Measure Implementation of Mitigation Measure NOI-1 is required. Significance after Mitigation With the implementation of Mitigation Measure MM NOI-1, vibration impacts causing human annoyance would be reduce to less than significant. The use of a small bulldozer would result in a RMS value at 10 feet of 70 VdB, which would be less than the impact threshold of 80 VdB. Operation Once construction activities have been completed, the potential vibration activities would occur when occasional maintenance is conducted by a large piece of equipment. Since the specific equipment is unknown, the potential impact could be considered significant. Mitigation Measure Implementation of Mitigation Measure N0I-1 is required. 6-105 Significance after Mitigation With the implementation of Mitigation Measure N0I-1, vibration impacts from operational activities associated with maintenance would be reduce to less than significant. C) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? Less than Significant Impact. After the completion of the project, there would be no noise generated sources in the project site. The potential noise generated activities would be occasional maintenance and repair activities throughout a year. It is assumed that maintenance and repair activities would occur within the hours indicated in the City's noise ordinance, Section 10.28.040. Therefore, the impact would be less than significant. d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? Less than Significant with Mitigation Incorporation. The project would temporary increase noise levels during construction phases. Construction of the proposed project would occur in multiple phases within a project boundary and is expected to last approximately five months. Construction phases and activities are presented in Table 3-14. TABLE 3-14 CONSTRUCTION SCHEDULE Phase Activity Duration Months Site preparation/ 1-2 weeks Month 1 Mobilization & Earthwork clearing/Grubbing Excavation and grading 2-3 weeks Months 1 and 2 Culvert extension 4-6 weeks Months 2 and 3 Drainage Structures and Piping Construction Dry weather diversion structures and 2-3 weeks Month 3 external piping Bioretention cell liner and piling 1-2 weeks Months 3 and 4 Water Quality System Bioretention cell media placement 1-2 weeks Month 4 Construction Bioengineering structure construction 1-2 weeks Month 4 OCSD Scope OCSD dosing station installation 4-6 weeks Months 3, 4, and 5 Restoration Site vegetation restoration 3-4 weeks Month 5 Construction activities occurring under each of these phases would require the use of heavy equipment (e.g., excavators, backhoes, loaders, tractors, etc.) along with the use of smaller power tools, generators, and other sources of noise. During each construction phase there would be a different mix of equipment operating and noise levels would vary based on the amount of equipment in operation and the location of each activity. As such, construction activity noise levels during each phase would fluctuate depending on the particular type, number, and duration of use of the various pieces of construction equipment. 6-106 Table 3-15 includes the list of construction equipment with quantity, usage per day, and estimated noise levels per phase. It should be noted that maximum noise levels associated with the construction equipment would only be generated when the equipment are operated at full power. Typically, the operating cycle for a piece of construction equipment would involve one or two minutes of full power operation followed by three or four minutes at lower power settings. As such, the maximum noise levels shown in Table 3-15 would only occur occasionally throughout the construction day. In addition to Table 3-15, hauling trucks would access the project site from Back Bay Drive and an access road through Big Canyon. Trucks would be very slow. However, trucks would be passing by within 100 feet of existing multi -family residential homes.

Noise levels for those equipment not included in this User's Guide are estimated based on similar equipment. SOURCE: ESA 2016. During the project's construction activities, the nearest and most notable off-site sensitive receptors to the construction site would be the existing multi -family residential uses to the north, which would be as close as 10 feet from the project boundary. Due to the use of construction equipment during the construction phases, the project would expose these sensitive receptors to increased exterior noise levels. Over the course of a construction day, the highest noise levels would be generated when multiple pieces of construction equipment are being operated concurrently. The City's noise ordinance, Section 10.28.040 limits construction hours to between 7:00 a.m. and 6:30 p.m. on any weekdays and between 8:00 a.m. and 6:00 p.m. on any Saturdays. It also prohibits construction activities on any Sundays and any federal holidays. Thus, the construction activities associated with the proposed project would be required to adhere to the applicable permitted hours of operation established under the City of Newport Beach's Noise Ordinance. However, although the proposed project's construction activities would only occur under the permitted hours allowed under the City of Newport Beach's Noise Ordinance, the proposed project would still expose the existing sensitive receptors located in proximity to the project site to increased exterior noise levels above existing ambient noise levels. It should be noted, however, that any increase in noise levels at the off-site sensitive receptors during project construction would be temporary in nature, and would not generate continuously high noise levels, although occasional single -event disturbances are possible. Nonetheless, because the temporary noise nuisance generated by the project's construction activities would constitute a substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project, this noise impact is considered to be potentially significant. Mitigation Measures NOI-2: The construction contractor shall ensure proper maintenance and working order of equipment and vehicles and that all construction equipment is equipped with manufacturers approved mufflers and baffles. NOI-3: The construction contractor(s) shall endeavor to use quieter equipment as opposed to noisier equipment (such as rubber -tired equipment rather than track equipment), when feasible. Noisy equipment shall be switched off when not in use. NOI-4: Construction activities shall be scheduled so as to avoid operating several pieces of equipment simultaneously, which causes high noise levels, to the extent feasible. NOI-5: The construction contractor shall place all stationary construction equipment so that emitted noise is directed away from sensitive receptors nearest the project site. Significance after Mitigation Implementation of Mitigation Measures NOI-2 through NOI-5, which would require the implementation of noise reduction devices and techniques during construction at the project site, would reduce the noise levels associated with construction of the proposed project to the maximum extent that is technically feasible, and this reduction would result in less than significant noise impacts. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? No Impact. The project site is located approximately 2.3 miles south of the John Wayne Airport. However, the project site is not within the airport's Noise Impact Zones, as specified by the Airport Environs Land Use Plan (AELUP) for John Wayne Airport (ALUC, 2008). Further, the project would not increase the amount of people living or working in the area, and would therefore, not expose people residing or working in the area to excessive noise levels. f) For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? No Impact. There are no private airstrips in the vicinity of the proposed project. Further, the project would not increase the amount of people living or working in the area, and would therefore, not expose people residing or working in the area to excessive noise levels.

The proposed project would not increase the number of residents within the City. Project construction would require a total of about 8 employees per day that would be employed temporarily during construction, and these employees would not induce population growth within the City. The duration of the project construction would last approximately five months, and it would not result in population growth in the area due to the project's temporary activities lasting only five months. Therefore, the project would result in no direct or indirect impacts to population growth in the project vicinity. b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? No Impact. The project site is located on open space land that is a natural habitat for various plant and wildlife species. There is no existing housing on the project site, no displacement of existing housing and no required replacement housing. No impact would occur. C) Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? No Impact. The project site is located on open space land that is utilized as a natural habitat for various plant and wildlife species. The project would not increase the number of residents within the City. Therefore, the project would not displace people and would not require the construction of replacement housing. No impact would occur.

PUBLIC SERVICES — Would the project: a) Result in substantial adverse physical impacts associated with the provision of, or the need for, new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for any of the following public services: i) Fire protection? ii) Police protection? iii) Schools? iv) Parks? v) Other public facilities?

No Impact. The Newport Beach Fire Department (NBFD) provides fire protection services for the entire City. The nearest NBFD fire station is Fire Station #3 located approximately 0.4 miles south of the project site at 868 Santa Barbara Drive. The proposed project would restore habitat, provide water quality features, and provide enhanced access to the project site for trail users. The proposed project could increase the use of the project area by increasing access and providing educational opportunities through the installation of interpretive signs along the trail. The project site could also provide learning opportunities for community and school groups. Although the project may increase the use of the project area, this increase would not result in a substantial number of trail users such that the fire department's service would be substantially affected. In addition, the enhancement of onsite access would allow the fire department improved access within the project site for emergencies. Because the proposed project is not altering the use of the project site (i.e., provision of trails), and the project would not substantially alter the number of trail users, the proposed project would not require the NBFD to provide new or physically altered facilities to serve the project site. Therefore, the implementation of the proposed project would result in no environmental impacts to new or physically altered fire department facilities because changes to these City facilities would not be required. 6-112 b) Police protection? No Impact. The Newport Beach Police Department (NBPD) provides local police services to the City of Newport Beach. The NBPD headquarters is located adjacent to NBFD Fire Station #3 at 870 Santa Barbara Drive. The proposed project would restore habitat, provide water quality features, and provide enhanced access to the project site for trail users. The proposed project could increase the use of the project area by increasing access and providing educational opportunities through the installation of interpretive signs along the trail. The project site could also provide learning opportunities for community and school groups. Although the project may increase the use of the project area, this increase would not result in a substantial number of trail users such that the police department's service would be substantially affected. In addition, the enhancement of onsite access would allow the police department improved access within the project site for emergencies. Because the proposed project is not altering the use of the project site (i.e., provision of trails) and the project would not substantially alter the number of trail users, the proposed project would not require the NBPD to provide new or physically altered facilities to serve the project site. Therefore, the implementation of the proposed project would result in no environmental impacts to new or physically altered police department facilities because changes to these City facilities would not be required. C) Schools? No Impact. The Newport -Mesa Unified School District (NMUSD) provides public educational services to the City of Newport Beach, as well as the City of Costa Mesa and other unincorporated areas of Orange County. The proposed project would not introduce new residents within the City. Therefore, the project would not increase the demand for school facilities. As a result, the proposed project would not require the NMUSD to provide new or physically altered school facilities. The project would result in no environmental impacts to new or physically altered school facilities because changes to school facilities would not be required. d) Parks? No Impact. The proposed project encompasses about 6 acres in the eastern portion of the 60 -acre Big Canyon Nature Park. The project site is designated as Open Space by the City General Plan, which is intended to "provide areas for a range of public and private uses to protect, maintain, and enhance the community's natural resources." The proposed project would enhance the recreational activities in the park by providing an extension of the existing trails to allow for pedestrian and bicycle travel. The official trail would allow access for the public to learn and enjoy the native habitats located within the park. The project's habitat restoration and access trails would enhance the quality of the park. The proposed project would not require the City to provide new or physically altered park facilities because these facilities would not be required to serve the project. Therefore, the implementation of the proposed project would result in no environmental impacts to new or physically altered park facilities. 6-113 e) Other public facilities? No Impact. The proposed project would introduce no new residents that would directly increase the City's population, and thus the project would result in no increase in the demand for other public services, such as libraries or hospitals. Therefore, the implementation of the proposed project would result in no environmental impacts to new or physically altered public facilities such as libraries and hospitals.

RECREATION — Would the project: a) Increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facilities would occur or be accelerated? b) Include recreational facilities or require the construction or expansion of recreational facilities that might have an adverse physical effect on the environment? Discussion a) Increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facilities would occur or be accelerated? Less than Significant Impact. The proposed project encompasses about 6 acres in the eastern portion of the 60 -acre Big Canyon Nature Park. The proposed project would enhance the recreational activities in the park by providing an extension of the existing trails to allow for pedestrian and bicycle travel. The official trail would allow access for the public to learn and enjoy the native habitats located within the park. The proposed project could increase the use of the project area by increasing access and providing educational opportunities through the installation of interpretive signs along the trail. The project site could also provide learning opportunities for community and school groups. Although the project may increase the use of the project area, this increase would not result in a substantial number of trail users such that the existing trails would result in substantial physical deterioration. The proposed project would result in a less than significant impact on the existing trails in the project area. b) Include recreational facilities or require the construction or expansion of recreational facilities that might have an adverse physical effect on the environment? No Impact. The proposed project includes the enhancement of recreational activities within a portion of the existing Big Canyon Nature Park. The implementation of these enhancements would not require additional recreational facilities to serve the project. Therefore, the project would not result in an adverse physical effect on the environment from the construction or expansion of additional recreational facilities because the project would not require additional recreational facilities.

TRANSPORTATION AND TRAFFIC — Would the project: a) Conflict with an applicable plan, ordinance or policy ❑ ❑ ® ❑ establishing measures of effectiveness for the performance of the circulation system, taking into account all modes of transportation including mass transit and non -motorized travel and relevant components of the circulation system, including but not limited to intersections, streets, highways and freeways, pedestrian and bicycle paths, and mass transit? b) Conflict with an applicable congestion management ❑ ❑ ❑ ❑ program, including, but not limited to, level of service standards and travel demand measures, or other standards established by the county congestion management agency for designated roads or highways? c) Result in a change in air traffic patterns, including ❑ ❑ ❑ either an increase in traffic levels or a change in location, that results in substantial safety risks? d) Substantially increase hazards due to a design feature ❑ ❑ ❑ (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? e) Result in inadequate emergency access? ❑ ❑ ❑ f) Conflict with adopted policies, plans, or programs ❑ ❑ ❑ regarding public transit, bicycle, or pedestrian facilities, or otherwise decrease the performance or safety of such facilities? Discussion a) Conflict with an applicable plan, ordinance or policy establishing measures of effectiveness for the performance of the circulation system, taking into account all modes of transportation including mass transit and non -motorized travel and relevant components of the circulation system, including but not limited to intersections, streets, highways and freeways, pedestrian and bicycle paths, and mass transit? Less than Significant Impact. The project site is assessable from Back Bay Drive and Jamboree Road by trail users as well as maintenance personnel. The implementation of the proposed project would result in an increase in traffic during construction activities and may result in minor increases in maintenance personnel trips during the operation of the project. During construction, approximately 8 employees will travel to the project site during the morning peak hour traffic period (i.e., prior to 9 am). Construction activities will require the use of haul trucks for vegetation and soil removal. The haul trucks would be used during the non -peak hours (i.e., after 9 am and prior to 4 pm). A maximum of 40 trucks per day during 6 hours each day would result in a maximum average of 7 trucks per hour. Trucks arriving to the site would travel along Jamboree Road, San Joaquin Hills Drive, and Back Bay Drive to the access road within Big 6-116 Canyon. Back Bay Drive is a one way roadway that provides northbound travel. Trucks exiting the project site would travel along the Big Canyon access road to Back Bay Drive to East Bluff Drive and then to Jamboree Road. The addition of 8 employee trips during the peak hour and an average of about 7 truck trips per hour during the non -peak hours would not result in substantial traffic effects at intersections or roadways in the project vicinity. b) Conflict with an applicable congestion management program, including, but not limited to, level of service standards and travel demand measures, or other standards established by the county congestion management agency for designated roads or highways? Less than Significant Impact. As stated above, the proposed project would result in a minimal amount of traffic trips to the surrounding street network. The applicable congestion management program is administered by the Orange County Transportation Agency (OCTA). According to the OCTA 2015 Congestion Management Program (CMP), the nearest CMP roadway is approximately 2 miles north of the project site at Jamboree Road and State Route 73. As stated above, the proposed project is anticipated to generate 8 employee trips during the peak hour and 7 truck trips during the non -peak hours. This level of traffic is considered minimal. According to the CMP Preparation Manual, a traffic impact analysis (TIA) is required for CMP purposes if a project generates 2,400 or more daily trips if the project does not directly access the CMP Highway System link, such as the proposed project (Orange County Transportation Authority, 2011). Because the project would generate a maximum of 40 trucks entering and 40 trucks exiting the site and up to 8 employee vehicles entering and 8 employees exiting the project site, the project would generate substantially fewer daily trips than the 2,400 or more daily trips that require a TIA to be prepared for CMP purposes. Therefore, the project would result in a less than significant impact on a CMP facility. C) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location, that results in substantial safety risks? No Impact. The implementation of the proposed project would include facilities that would not affect air traffic patterns. The nearest airport to the project site is John Wayne Airport which is located approximately 2.3 miles north of the project site. d) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? No Impact. The project site currently contains a maintenance access off of Jamboree Road. The proposed project includes a modified maintenance road access that is perpendicular to Jamboree Road. The proposed access would meet the City of Newport Beach design requirements for maintenance roads. In addition, construction vehicles are proposed to access Back Bay Drive. The current speed limit for vehicles on Back Bay Drive is 15 miles per hour. Construction vehicles associated with the proposed project would limit speeds on Back Bay Drive to 15 miles per hour to ensure traffic safety for pedestrians, bicyclists and equestrian users of the trail along Back Bay Drive. In addition, as part of a standard City procedure during public works projects, signs will be 6-117 posted along Back Bay Drive regarding the construction activities and duration. Therefore, the proposed project would not result in increasing hazards due to a design feature. e) Result in inadequate emergency access? No Impact. Project construction activities would be located on the project site and would not require any lane closures. In addition, project operational activities will not require lane closures or impact emergency access. The provision of additional trail segments on the project site would provide greater access to the project area, but would not adversely affect emergency access. Therefore, the project would not impact emergency access to the project site or areas in the vicinity of the project site. f) Conflict with adopted policies, plans, or programs regarding public transit, bicycle, or pedestrian facilities, or otherwise decrease the performance or safety of such facilities? No Impact. The implementation of the proposed project would not conflict with policies, plans or programs related to public transit, bicycle or pedestrian facilities. Back Bay Drive currently has public transportation facilities, including a one way vehicular pathway. The project construction vehicles would use the one-way vehicular pathway and limit their speeds to the existing 15 miles per hour limit.

Significant Mitigation Significant Issues (and Supporting Information Sources): Impact Incorporation Impact No Impact 17. UTILITIES AND SERVICE SYSTEMS — Would the project: a) Conflict with wastewater treatment requirements of ❑ ❑ ❑ ❑ the applicable Regional Water Quality Control Board? b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? ❑ ❑ ® ❑ c) Require or result in the construction of new storm ❑ ❑ ❑ water drainage facilities, or expansion of existing facilities, the construction of which could cause significant environmental effects? d) Have sufficient water supplies available to serve the ❑ ❑ ❑ project from existing entitlements and resources, or are new or expanded entitlements needed? e) Result in a determination by the wastewater treatment ❑ ❑ ® ❑ provider that would serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? f) Be served by a landfill with sufficient permitted ❑ ❑ ® ❑ capacity to accommodate the project's solid waste disposal needs? g) Comply with federal, state, and local statutes and ❑ ❑ ❑ regulations related to solid waste? Discussion a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? No Impact. The Regional Water Quality Control Board, Santa Ana Region, issued a National Pollutant Discharge Elimination System (NPDES) permit that implements federal and state law governing point source discharges and nonpoint source discharges to surface waters of the United States. Construction and operation of the proposed project includes a wastewater pipe that would allow selenium -concentrated water from seeps to be conveyed to the existing wastewater pipe located along Jamboree Road. The wastewater would be conveyed to the Orange County Sanitation District treatment facilities. The amount and frequency of discharged selenium wastewater would be nominal, and the proposed project would not exceed OCSD's wastewater treatment requirements of the Santa Ana Region of the Regional Water Quality Control Board. Thus, the project would not impact existing wastewater treatment requirements. 6-119 b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? No Impact. The proposed project would not require the construction of a new water or wastewater treatment facility or expansion of the existing treatment facilities serving the project vicinity. The project requires no potable water supply for the project site. The project would involve the extension of an existing sewer conveyance within the project site, but would not require the extension of any existing water or wastewater facilities off the project site. Therefore, the proposed project would result in no impact requiring the construction of water or wastewater treatment facilities. C) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? No Impact. The proposed project would not require the construction of new stormwater drainage facilities. The project itself includes the construction of a primary stormwater treatment structure to trap and pretreat contaminants prior to conveyance to the bioretention cell. The project would not require the addition of a storm drain conveyance or the expansion of any stormwater drainage facilities since the project aims to restore the natural habitat and improve water quality within the creek. With the implementation of these features, the proposed project would not require the construction of new storm water drainage facilities or expansion of existing facilities off site. Therefore, the project would result in no environmental effects from new storm water drainage facilities or expansion of existing facilities to serve the proposed project. d) Have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? No Impact. The City of Newport Beach's water supply is provided by the Municipal Water District of Orange County. The construction and operation of the proposed project requires no use of imported water supply from existing water resources. Thus, the project would result in no need for new or expanded water supply entitlements, and no impacts would occur. e) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? Less than Significant Impact. Wastewater collected by the Sanitary District is sent to the County Sanitation Districts of Orange County (County Sanitation) plants for treatment and disposal. Wastewater is treated at County Sanitation's treatment plants in Fountain Valley and Huntington Beach. According to County Sanitation's treatment plant operational data, the combined effluent treated at both plants is approximately 200 million gallons daily (average). County Sanitation operates under an NPDES ocean discharge permit issued by the California Regional Water Quality Control Board (OCSD, 2016). The project's increase in selenium 6-120 wastewater would be infrequent and not be substantial. Project implementation would contribute a nominal amount of wastewater and would not cause the treatment plants' operating capacities to be exceeded. Therefore, the proposed project would result in a less than significant impact to wastewater treatment capacity. f) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? Less than Significant Impact. The project site would be served by the solid waste facilities and landfills that are operated by the Orange County Waste and Recycling (OCWR). The nearest landfill to the project location is the Frank R. Bowerman Sanitary Landfill in Irvine, and is the only landfill that serves the City of Newport Beach. The Bowerman Landfill is permitted as a Class III landfill to receive a daily maximum of 11,500 tons per day. Class III landfills accept only non -hazardous municipal solid waste for disposal; no hazardous or liquid waste can be accepted. It is currently estimated to operate with adequate capacity until 2053. The landfill is required to comply with numerous landfill regulations from federal, state and local regulatory agencies (OCWR, 2016). Project implementation would result in the need for disposal of debris from construction and maintenance activities. Solid waste removed from the project site would include dead or non- native vegetation. Debris would be removed with construction equipment and transported to the landfill by haul trucks. It is anticipated that the project's generation of solid waste would be at its greatest during initial construction activities due to the primary removal of non-native habitat vegetation. Thereafter, the project would result in minimal removal of dead vegetation during operational maintenance activities. Given the project's scale, it is anticipated that the specified landfill would have the adequate capacity to accommodate the project's waste disposal needs. Therefore, the project would result in a less than significant impact to landfill capacity. g) Comply with federal, state, and local statutes and regulations related to solid waste? No Impact. Construction and operation of the proposed project would result in the disposal of dead or non-native vegetation to the Frank R. Boweman Sanitary Landfill in Irvine. The disposal of vegetation would comply with federal, state, and local statutes related to solid waste. No impact to these regulations would occur with project implementation.

MANDATORY FINDINGS OF SIGNIFICANCE Would the project: a) Have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory? b) Have impacts that are individually limited, but ❑ ® ❑ cumulatively considerable? ("Cumulatively considerable' means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? c) Have environmental effects that would cause substantial adverse effects on human beings, either directly or indirectly? Discussion a) Have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory? Less than Significant with Mitigation Incorporated. Construction activities associated with the proposed project could impact nesting birds, vegetation communities such as riparian and wetland habitat and could temporarily disrupt wildlife movement. These potential impacts to these biological resources would be significant. Construction activities could also impact historical or prehistorical resources. Although no resources are known to occur on the project site, there is a potential for unknown historical or prehistorical resources to be located on the project site based on resources found in the project vicinity. These potential unknown resources could be significantly affected. Mitigation Measures Implementation of Mitigation Measures 13I0-1 through 13I0-3, CR -1 and CR -2 is required. 6-122 Significance after Mitigation The implementation of Mitigation Measures BIO -1, BIO -2, and BIO -3 to reduce these potential impacts on biological resources to less than significant. The implementation of Mitigation Measures CR -1 and CR -2 would reduce potential impact to historical and prehistorical resources to less than significant. b) Have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? Less than Significant with Mitigation Incorporated. Based on a review of the City of Newport Beach Cumulative Projects List, there are various projects in different planning stages that are located within two miles of the project site; however, only one project (one new residence) that is located upstream within Big Canyon of the project site. The various projects include an Autonation (about 2.0 miles from the site), Environmental Nature Center Preschool (about 1.7 miles from the site), condominium development at Newport Center Villas (about 1.0 mile from the site), mixed-use development at Back Bay Landing (about 1.5 miles from the site), Balboa Marina expansion (about 1.7 miles from the site), medical offices (about 1.7 miles from the site), a residence (about 0.4 mile from the site), construction of a clubhouse at Newport Beach Country Club (about 1.0 miles from the site), condominium units (about 0.6 mile from the site), and a commercial development (about 2.0 mile from the site). As discussed in Section 3 of this IS/MND, the proposed project would result in significant impacts to biological resources, cultural resources, vibration, and construction noise. The project would substantially contribute to potential cumulative impacts to each of these environmental components. As a result, the project's contribution to cumulative impacts associated with biological resources, cultural resources, vibration, and construction noise would be cumulatively considerable. Mitigation Measures Implementation of Mitigation Measures BIO -1 through BIO -3, CR -1 through CR -3, and NOI-1 through NOI-5 is required. Significance after Mitigation With the implementation of the above mitigation measures, the project's contribution to cumulative impacts associated with biological resources, cultural resources, vibration, and construction noise would be reduce to less than significant. C) Have environmental effects that would cause substantial adverse effects on human beings, either directly or indirectly? 6-123 Less than Significant with Mitigation Incorporated. The implementation of the proposed project could result in temporary noise increases during construction as well as vibration impacts during construction. These noise and vibration impacts could represent significant adverse effects on human beings. Mitigation Measures Implementation of Mitigation Measures NOI-I through NOI-5 is required. Significance after Mitigation The implementation of the above mitigation measures would reduce the potential vibration impacts as well as the construction noise level on the adjacent residents. This reduction in impact would result in a less than significant noise and vibration impact. 6-124 Exhibit 2a BIG CANYON HABITAT RESTORATION & WATER QUALITY IMPROVEMENT PROJECT Final Initial Study and Mitigated Negative Declaration Prepared for April 2016 City of Newport Beach Public Works Department ESA J BIG CANYON HABITAT RESTORATION & WATER QUALITY IMPROVEMENT PROJECT Final Initial Study and Mitigated Negative Declaration Prepared for April 2016 City of Newport Beach Public Works Department ESA 626 Wilshire Boulevard Suite 1100 Los Angeles, CA 90017 213.599.4300 www.esassoc.com Irvine Oakland Orlando Palm Springs Petaluma Portland Sacramento San Diego San Francisco Seattle Tampa Woodland Hills 130934.00 TABLE OF CONTENTS Big Canyon Habitat Restoration & Water Quality Improvement Project Initial Study Page 1.

This Initial Study addresses the indirect, direct, and cumulative environmental impacts associated with the proposed project. The proposed project includes the following (1) restore historic riparian habitat by removing non-native vegetation and replace it with native plantings, (2) stabilize the creek and floodplain, (3) improve water quality in Big Canyon Creek and Newport Bay, and (4) enhance public access within the Big Canyon Nature Park. The project also includes maintenance of the proposed water quality features to ensure that the features are functioning as originally designed. 1.1 Statutory Authority and Requirements In accordance with the CEQA (Public Resources Code Sections 2100-21177) and pursuant to Section 15063 of Title 14 of the California Code of Regulations (CCR), the City of Newport Beach, acting in the capacity of Lead Agency, is required to undertake the preparation of an Initial Study to determine if the proposed project would have a significant environmental impact. If the Lead Agency finds that there is no evidence that the project, either as proposed or as modified to include the mitigation measures identified in the Initial Study, may cause a significant effect on the environment, the Lead Agency must find that the project would not have a significant effect on the environment and must prepare a Negative Declaration or Mitigated Negative Declaration for that project. Such determination can be made only if, "there is no substantial evidence in light of the whole record before the Lead Agency" that such impacts may occur (Section 21080(c), Public Resources Code). The environmental documentation is intended as an informal document undertaken to provide an environmental basis for subsequent discretionary actions upon the project. The resulting documentation is not, however, a policy document and its approval and/or certification neither presupposes nor mandates any actions on the part of those agencies from whom permits and other discretionary approvals would be required. The environmental documentation and supporting analysis is subject to a public review period. During this review, public agency comments on the document should be addressed to the City of Newport Beach. Following review of any comments received, the City of Newport Beach will consider these comments as part of the project's environmental review and include them with the Initial Study documentation for consideration by the Planning Commission of the City of Newport Beach. Big Canyon Habitat Restoration and Water Quality Improvement Project ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist 1.2 Purpose The City of Newport Beach (City) has prepared this IS/MND to provide the public and responsible agencies with information about the potential environmental impacts associated with implementation of the proposed Big Canyon Creek Restoration and Water Quality Improvement Project. This IS/MND includes project -level analysis of the potential effects associated with the project. This IS/MND was prepared in compliance with Sections 15070 to 15075 of the California Environmental Quality Act (CEQA) Guidelines of 1970 (as amended) and California Code of Regulations, Title 14, Division, Chapter 3. In accordance with Section 15070, an MND shall be prepared if the Initial Study identifies potentially significant effects, but revisions in the project plans would avoid or mitigate the effects to a point where clearly no significant effects would occur. As the CEQA lead agency, the City has determined that an IS/MND shall be prepared for the proposed project. 1.3 Response to Comments In accordance with California Environmental Quality Act (CEQA) Guidelines Section 15073, the City of Newport Beach (City) circulated the Proposed Mitigated Negative Declaration (MND), State Clearinghouse No. 2016031011, for the Big Canyon Habitat Restoration & Water Quality Improvement Project for a 30 -day public review period from March 4, 2016 through April 4, 2016. The City received three comment letters from State agencies (Governor's Office of Planning and Research, California Department of Fish and Wildlife, and Santa Ana Regional Water Quality Control Board) and verbal comments from the City of Newport Beach Planning Department on the content of the IS/MND. Responses to each of the comments are provided in Appendix E, Response to Comments Letter that were received on the Proposed MND for the proposed project, clarified, amplified, and expanded on the adequate analysis and significance conclusions that were already set forth in the Proposed MND. CEQA Guidelines Section 15073.5 makes clear that such clarifications and amplifications are appropriate under CEQA and do not require recirculation of the Proposed MND. Responses that resulted in revisions and clarifications of the information in this Final MND are identified as underlined text for additions and int for deleted text. None of the revisions or clarifications change the significance of the conclusions provided in the Proposed MND or substantially altered the analysis presented for public review. Big Canyon Habitat Restoration and Water Quality Improvement Project 1-2 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 CHAPTER 2 Project Description 2.1 Introduction The Big Canyon Restoration and Water Quality Improvement Project (proposed project) is located on a 6 -acre site in the eastern portion of the 60 -acre Big Canyon Nature Park at the downstream end of the Big Canyon Watershed in the City of Newport Beach (City), Orange County, California (Figure 1). The Big Canyon Watershed covers approximately two square miles located on the east side of Upper Newport Bay. Big Canyon Creek winds through the Big Canyon Nature Park in a general southeast to northwest direction and then discharges into Upper Newport Bay. Big Canyon is the only natural, undeveloped portion of the Big Canyon watershed and the only significant remaining natural canyon on the east side of Newport Bay. The upper 45 -acre parcel is owned by the City of Newport Beach. The lower 15 -acre portion of the Nature Park is owned the California Department of Fish and Wildlife and is a part of the Upper Newport Bay State Ecological Reserve. 2.1.1 Project Background The City has contemplated restoration efforts within Big Canyon for over a decade. Currently, the City has funding for the restoration efforts that are part of Phases IA and IB (proposed project). Potential future restoration efforts could also be proposed as a separate project, if future funding is available. The proposed project is currently being planned in coordination with a Resource and Recreation Management Plan (RRMP) being prepared by the Irvine Ranch Conservancy under contract with the City of Newport Beach for the Big Canyon Nature Park. The RRMP provides a framework for restoration and recreational improvements in the Nature Park that will be consistent with the requirements of the Natural Community Conservation Plan/Habitat Conservation Plan (NCCP) for the Central and Coastal sub -region of Orange County in the event the City elects to incorporate the Nature Park into the NCCP. Potential future restoration efforts within Big Canyon would also be coordinated with the RRMP.

D130934 Figure 1 Regional Location Map 3. Environmental Checklist The potential future restoration efforts could provide benefits to Big Canyon in addition to those associated with the proposed project. These benefits could include water quality improvements in Big Canyon Creek, restoration of natural creek channels impacted by hydromodification, restoration of riparian and inland alkaline non -tidal marsh habitat, removal of non-native vegetation and replacement with native plantings, remediation of selenium -laden sediment within former freshwater ponds, creation of new transitional habitat to allow for future adaption of coastal estuarine habitat due to sea -level rise, reduction of favorable mosquito breeding habitat, and improvements and protection of public access within the natural areas of the Big Canyon Nature Park, including coastal areas that will be subject to future inundation due to sea -level rise. If funding is available, the City anticipates the preparation of a feasibility analysis to develop the least impactful and most cost-effective approach to the freshwater ponds for the future restoration efforts. These future efforts could include the protection of the biological resources within the creek and downstream estuary by addressing the sediment and reeds within these ponds and restoring the area of the future efforts. This potential future area currently contains invasive pepper trees, and the City contemplates removal of them so that the area could be restored to a transitional habitat to allow for adaptation of the coastal estuary due to sea -level rise. Based on projected sea -level rise, this area of invasive pepper trees could be inundated in about 50 years. Phases IA and IB, the current project, include the implementation of a creek and riparian habitat restoration, habitat creation and enhancement, stormwater treatment wetland, dry -weather flow diversions, culvert improvements, and trail planning in the upper portion of the Big Canyon Nature Park. Implementation is scheduled for 201017. 2.1.2 Purpose and Need for Project The Big Canyon Restoration Project — Phases IA and IB will: (1) restore historic riparian habitat by removing non-native vegetation and replace it with native plantings, (2) stabilize the creek and floodplain, (3) improve water quality in Big Canyon Creek and Newport Bay, and (4) enhance public access within the Big Canyon Nature Park. Restoration and water quality improvements in Phase I will proceed potential future restoration efforts in the remaining downstream areas of the watershed. 2.1.2.1 Restore Historic Riparian Habitat Big Canyon Creek has been documented as suitable for habitat restoration and enhancement due to channel incision, loss of floodplain access, unstable banks, poor water quality, and more than anything invasive species. Large portions of the riparian habitat are dominated by non-native invasive species. This in turn has impacted the habitat quality of the riparian habitat in and along Big Canyon Creek within the project area as well as in the downstream reaches of the Nature Park. 2.1.2.2 Creek and Flood Plain Stabilization Urbanization in the Big Canyon watershed has resulted in increased peak and sustained peak storm flows that have resulted in hydraulic modification of the Big Canyon Creek within the Big Canyon Habitat Restoration and Water Quality Improvement Project 2-3 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist project limits. Downstream of the Jamboree Road culvert, Big Canyon Creek has responded to hydromodification by incising into its historic channel bed and eroding channel banks in the upper reach of the creek. Channel incision has reduced floodplain connectivity in the adjacent riparian community that requires periodic inundation to support native biological species and habitat conditions. Continued erosion and channel cutting will result in unstable embankments. Flooding has also occurred historically at the site and has resulted in damage to Back Bay Drive. Without the proposed creek and watershed restoration measures, the ongoing physical, chemical and biological processes will result in additional bank and bed erosion, continued loss of riparian habitat, reduced water quality in the creek and in Newport Bay, and loss of opportunities to provide effective educational and recreational elements that serve the wider Orange County. In addition a mosquito vector habitat is created when wet weather flows from Jamboree Road discharge through a storm drain outfall to a scour pond in the creek's riparian corridor. This project addresses this mosquitos breeding habitat by eliminating the scour pond. 2.1.2.3 Water Quality Improvements During wet weather, roadway -related pollutants (e.g., metals, sediment, oil and grease) enter Big Canyon Creek from thoroughfares such as Jamboree Road and impact creek water quality. The project includes measures to reduce metals and sediment loading into the creek and Bay from stormwater flows from Jamboree Road. Big Canyon Creek is listed as an impaired waterbody for selenium_ and a A total maximum daily load (TMDL) for selenium is under development that will address Big Canyon Creek and other freshwater tributaries in the Newport Bay watershed. The receiving water for Big Canyon Creek is Newport Bay, which is listed as an impaired waterbody for metals, toxics, nutrients, and bacteria. TMDLs have also been established to address these impairments. Big Canyon Creek, which drains the Big Canyon Watershed, is one of the few perennial streams that discharge to Upper Newport Bay. Concentrations of selenium above applicable water quality criteria for selenium (California Toxics Rule chronic freshwater criteria) guidelines have been measured in dry weather flows in Big Canyon Creek. The City has developed and is implementing a selenium reduction program in the watershed that includes dry weather diversions and other measures to reduce the selenium concentrations in the creek and into Upper Newport Bay. This project includes additional measures to substantially reduce selenium loading in dry weather flows as part of the selenium reduction program. To address these issues, the proposed project would construct a bioretention cell water quality treatment wetland that would treat wet weather flows and would also minimize the storm drain - associated vector habitat in Big Canyon Creek. Additional water quality measures include the construction of a dry weather flow diversion that re-routes flows of low selenium concentration around identified sources of high selenium and return these better quality flows back into the creek downstream. Seeps that are sources of high selenium will be passively collected and diverted to the sanitary sewer.

Environmental Checklist Without the proposed water quality measures as part of Phase IA and IB of the Big Canyon Restoration Project, impacts to water quality and biological beneficial uses will continue. The success of the planned restoration efforts as part of this phase and potential future downstream phases depends on addressing the existing water quality issues. These measures are needed for the long-term sustainability of the restoration of Big Canyon. 2.1.2.4 Public Access Enhancements Big Canyon Nature Park is used by residents and visitors for passive recreation. This is an important destination for thousands of children participating in the Orange County Department of Education Inside the Outdoors program. Inside the Outdoors provides watershed educational activities for grade school children throughout the county including disadvantage communities. As the largest undeveloped canyon adjacent to Newport Bay, it has the potential to become an integral part of the Upper Newport Bay State Ecological Preserve and to provide unique opportunities for the public to learn about the diversity of biological resources and environmental protection within a short walking distance. At present, the upper portions of the Nature Park are not attractive and rarely visited by the public. Along with habitat restoration, trail improvement and information signage will provide an enhanced experience of the different ecotones in a coastal watershed. 2.2 Project Location and Setting The proposed project is located within the City of Newport Beach, on a 6 -acre site in the eastern portion of the 60 -acre Big Canyon Nature Park. As shown in Figure 1, the project site is east of Upper Newport Bay, west and east of Jamboree Road and includes Big Canyon Creek. Primary regional access to the project site is provided by State Route 73, which runs north -south approximately 2 miles north of the project site, and State Route 1, which runs north -south approximately 1.25 miles south of the project site. Sub -regional access is provided via Jamboree Road, Ford Road, and San Joaquin Hills Road. The project site is bounded by residential developments on the bluffs to the north and south. Land uses within the project vicinity include residential, recreational open space, golf courses, and commercial developments (Figure 2). Located on the east side of Upper Newport Bay, Big Canyon Creek winds through the Big Canyon Nature Park in a general southeast to northwest direction and then discharges into Upper Newport Bay. The Big Canyon watershed is roughly 1,300 acres extending roughly 3 miles east from Back Bay Drive into the San Joaquin Hills. Big Canyon is the only natural, undeveloped portion of the Big Canyon watershed and the only significant remaining natural canyon on the east side of Newport Bay. This 45 -acre parcel contains native and non-native habitat and an array of hiking trails, and is owned by the City of Newport Beach (Figure 3). Directly downstream of the Project Area, the lower 15 -acre portion of the Nature Park is owned by the California Department of Fish and Wildlife (CDFW) and is a part of the Upper Newport Bay State Ecological Reserve. Big Canyon Nature Park is located in the Upper Newport Bay State Marine Conservation Area (SMCA) and is part of Southern California's coastal estuarine environment. Newport Bay discharges adjacent to the Newport Coast Area of Special Biological Significance (ASBS).

D130934 Figure 3 Project Aerial Map 3. Environmental Checklist The Project Area is characterized topographically by steeply sloping bluffs and a narrow, moderately -sloped floodplain; slopes range in elevation from 20 to 75 feet above mean sea level and the canyon creek ranges in elevation from below mean sea level to 25 feet above mean sea level. A perennial stream identified as Big Canyon Creek is present within the Project Area and supports degraded riparian habitat. The Project Area supports six plant communities, as well as disturbed and developed areas (Figure 4, Vegetation Communities). These plant communities include southern riparian forest, freshwater march, alkali meadow, Diegan sage scrub, non-native grassland, and ornamental habitat—of these, southern riparian forest, freshwater march, alkali meadow, and Diegan sage scrub habitats are considered to be sensitive plant communities. Sensitive habitats are those considered to support unique vegetation communities and/or special -status plant and/or wildlife species, or function as corridors for wildlife movement. The southern riparian forest habitat is heavily impacted by the invasion and establishment of invasive trees and understory vegetation. A total of 194 species of invasive and non-native grasses, forbs, and trees have been identified within the Big Canyon Nature Park (Dudek 2015). The Big Canyon Project Area is bound on three sides by development. On the east side of Jamboree, the Project Area is bound by the golf course to the east and south, and a condominium complex to the north. On the west side of Jamboree Road, residential development is located at the north and south side of the Project Area. To the west, the Big Canyon Nature Park extends to Upper Newport Bay State Ecological Reserve.

Environmental Checklist 2.3 Project Overview and Design The proposed project has several objectives including: • Restore and Enhance Riparian Habitat • Improve Water Quality • Reduce Flood/Erosion/Sedimentation Damage • Encourage Public Participation and Provide Education • Provide Recreational Opportunities In order to meet these objectives, the proposed project includes the following elements: • Creek Restoration and Riparian Habitat Creation & Enhancement — The project proposes to conduct creek restoration activities that will include floodplain restoration, streambank stabilization, and habitat restoration. Floodplain restoration and streambank stabilization activities will result in increased flood flow attenuation, stabilization of the north bank of the main channel, and creation of an active braided riparian floodplain. The north creek bank at the inlet will be stabilized using natural bioengineering techniques. Riparian habitat will be restored directly downstream of the floodplain restoration area through the removal of invasive trees, soil modification to reduce plant -limiting sodium levels, and replacement with native riparian species. • Riparian Habitat Creation Activities — Riparian habitat creation activities will also be conducted directly to the southwest of the proposed bioretention cell. This area will be graded down to allow for riparian trees to access existing groundwater. Riparian habitat enhancement will include removal of upstream and adjacent sources of Brazilian peppertree both east of Jamboree Road and north of the creek. • Stormwater Water Quality Treatment Bioretention Cell — The project includes the construction of a water quality treatment bioretention cell that will treat wet -weather flows from Jamboree Road and reduce the storm drain -associated vector habitat in Big Canyon Creek. The basin will be vegetated with coastal sage scrub on the outer banks and vegetated with native riparian forbs, grasses, and shrubs in the inner basin. These species will have the ability to sequester toxins and tolerate flooded conditions for limited periods of time. The basin will be periodically maintained per an approved Operation and Maintenance Plan. • Dry Weather Water Quality Selenium Reduction Measures — A dry weather flow diversion that re-routes flows of lower selenium concentration around identified sources of high selenium and return these better quality flows back into the creek will be constructed as part of this project. Dry weather flows will be diverted from an underground culvert on the east side of Jamboree Road and routed through an above ground pipe along the south bank of the creek and through the storm drain culvert under Jamboree Road. The pipe will discharge on the west side of Jamboree Road into the floodplain that will be graded as part of this project. Seeps that are sources of high selenium will be passively collected and diverted to the sanitary sewer. Big Canyon Habitat Restoration and Water Quality Improvement Project 2-10 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist Infrastructure Improvements — The Project will also be constructed in coordination with infrastructure improvements by the Orange County Sanitation District (OCSD). The improvements are shown on Figure 3 and include the extension and improvement of the existing access road along the toe of slope along the west side of Jamboree Road. The access road improvements will be used access and maintain the sanitary sewer manhole located to the north of the existing culvert outfall. The construction of the access road to and over the existing culvert under Jamboree Road requires the extension of the culvert as shown on Figure 3. A concrete stilling pool will be located at the end of the culvert extension to dissipate hydraulic energy as the stormwater transitions from flow in the culvert and discharges to the regraded floodplain. This stilling pool will be periodically maintained to remove sediment and vegetation. Water from the stilling pool will exit via a rip rap energy dissipater. The stilling basin will be designed to address ponded water after storm events using orifice type outlets for low flows. Collection of dry weather seeps from the creek on the east side of Jamboree Road will be directed to the stilling basin and then directed to the OCSD sanitary sewer. The system will be designed to avoid ponding in the stilling basin for more than 72 hours, which will minimize the support of aquatic insects, fish or other aquatic organisms that might be attractive to birds. OCSD will also install a permanent dosing station and access area located to the south of the proposed habitat creation area. Community Access Improvements and Educational Opportunities — The extended access road will provide an official trail where the public can learn about and enjoy the native habitats. In addition, an 8 -foot -wide bicycle path connector will be installed to provide access directly from Jamboree Road. In addition, the maintenance road at the top of the bioretention cell will also be used as a side viewing trail with interpretive signs installed. Visitors using this trail will cross from the south to the north side of the creek via the OCSD constructed turnaround area over the culvert, and follow a footpath on the north side of the creek. The footpath on the north side of the creek will continue within the coastal sage scrub habitat, following existing ad hoc trails that will be expanded to approximately 42 -inches wide. Trails allow for educational opportunities regarding water quality and creek restoration activities, and through the installation of signage and as - needed fencing, will keep the public out of sensitive habitats. 2.4 Project Components As shown in Figure 5, the proposed project consists of habitat restoration, creation and enhancement of riparian habitat, water quality improvements, and infrastructure and trail improvements. 2.4.1 Creek Restoration, Creation and Riparian Habitat Enhancement This project consists of creek restoration and riparian habitat creation and enhancement activities including stream bank stabilization, floodplain restoration, habitat creation, and restoration of riparian habitat through invasive plant removal, soil remediation and revegetation. Big Canyon Habitat Restoration and Water Quality Improvement Project 2-11 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist 2.4.1.1 Floodplain Restoration & Streambank Stabilization Directly downstream of the new culvert placement and stilling basin where Big Canyon Creek flows into the Project Area, the project will create and restore the creek's active floodplain (Figure 6, Riparian Habitat Restoration Areas). The main channel is currently incised and is confined to the incised narrow creek bed. The existing area to the south of the creek would be lowered by approximately 6 feet to create a floodplain 2 to 3 feet above the low -flow channel to allow for frequent inundation during high-flow events. The 150 feet of channel and floodplain downstream of the stilling basin will be restored to eliminate unstable eroding banks and a disconnected floodplain. A bankfull channel has been sized using Dunne and Leopold's (1978) regional hydraulic geometry for California creek dimensions, cross-checked against the downstream stable section as a reference reach. For a watershed of 1.7 square miles (as delineated using the USGS StreamStats web application), this produces a bankfull width of 19 feet and a bankfull depth of 1.8 feet (rounded to 20 feet and 2 feet, respectively), very similar to the downstream channel width and depth in the more stable area. For the restored reach, the existing channel invert elevation was retained. The channel will be realigned away from the eroding and undercut north bank into the center of the floodplain, and a new floodplain will be created on both banks. The floodplain and channel will be sized so that flows exceeding the 2 -year recurrence event start to inundate the floodplain. On the south bank (river left, looking downstream) a 20 -foot -wide floodplain will be created by cutting into the existing over -steepened bank and upland terraces currently dominated by non- native grasses as well as degraded riparian habitat. There will be a net reduction in fill within the floodway, and an increase in both conveyance and frequently activated floodplain. On the north bank (river right, looking downstream) the floodplain will be stabilized by adding vegetated soil lifts. Encapsulated vegetated soil lifts planted with willows and other native vegetation will be used to construct and protect the banks, and to provide erosion control. The vegetated soil lifts will be constructed in 1 -foot -thick lifts containing the native alluvial soil from the site and amendments, with each lift encapsulated in coir fiber that will biodegrade over the first 2-3 years, once the incorporated native riparian vegetation has established. Each lift will be separated from the next by a layer of locally sourced native live willow stems that will grow following installation. For the cut banks (river left) willow brush mats will be placed over the cut bank and secured with biodegradable coir fabric, then secured with biodegradable rope and wooden stakes. Both cut and filled banks will be reinforced with biotechnical materials up to the 100 -year water surface elevation. This will serve to stabilize the grade and act as a planting medium for the growth of riparian vegetation.

Environmental Checklist This page left intentionally blank Big Canyon Habitat Restoration and Water Quality Improvement Project 2-14 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist 2.4.1.2 Riparian Restoration & Soil Modification Directly downstream of the floodplain restoration area, the riparian habitat will be restored to its full functioning system (see Figure 6 and Figure 7, Habitat Mitigation Areas). Under current conditions, invasive trees and an extensive understory of non-native forbs and grasses have been documented. Bermuda grass (Cynodon dactylon), periwinkle (Vinca major), pampas grass (Cortaderia selloana), and English ivy (Hedera helix) are just a few of the highly invasive grasses and forbs found under the existing canopy. These invasives are better able to compete under the high -saline soil conditions that are found within Big Canyon. Brazilian peppertree is the most prevalent invasive tree species found in the canyon. The origins of this seed source can be traced to two sources: (1) east of Jamboree Road, Brazilian peppertree has established on the slopes of the Big Canyon drainage and adjacent upland area, with the seed source directly flowing into the canyon; and (2) the west side of Jamboree Road directly to the north of the creek also has this species growing on the slopes. The trees, forbs, and grasses will be aggressively removed as part of this project. Mature trees will be removed during mass grading and isolated individuals will be killed in place without soil disturbance. Soil testing results have indicated extremely high levels of sodium, boron, and sulfur in the soils. Brazilian pepper tree's high tolerance for these extreme levels of normally plant -inhibiting levels indicates the reason this species is so successful in Big Canyon. Following invasive removal, the soil will be amended to levels where native riparian vegetation can persist. The soil amendment regiment will be incorporated directly into the top layers of soil following plant removal. Details of the soil modifications will be included in the Habitat Restoration Plan prepared for this project. Following soil modification, all areas will be actively planted, seeded, and maintained, with topically applied soil treatments continuing through plant establishment, as prescribed. 2.4.1.3 Wetland/Riparian Habitat Creation Additional riparian habitat will be created to the southwest of the proposed bioretention cell. This will result in the expansion of contiguous riparian habitat, and will serve as part of the required mitigation as replacement for some of the habitat lost as a result of implementation of other components of this project (see Figure 7). This area has been previously disturbed and consists of early successional forbs and grasses, providing low habitat value. Groundwater has been measured in this area with a temporary piezometer at 5-7 feet below the existing ground surface. The area will be graded to lower current ground elevations to access this permanent water source to an elevation of approximately 39 feet mean sea level. A reduction of the elevation within the creation area and in the existing riparian area to the west of the creek will bring the ground level closer to the groundwater table, thereby allowing for establishment of riparian vegetation that will be planted following grading and soil preparation activities. The discharge of the stormwater treatment wetland will also be routed to this area to provide for periodic inundation during storm events. The areas will also be subject to flooding during larger storm events, but will not pond water or create a vector issue.

D130934 Figure 7 Habitat Mitigation Areas for Impacts to Jurisdictional Resources 3. Environmental Checklist 2.4.2 Water Quality Improvements The project includes measures to treat storm flows and dry -weather flows that will result in improved water quality for habitat and wildlife in Big Canyon. 2.4.2.1 Stormwater Treatment System (Primary Stormwater Treatment Structure, Bioretention Cell) The purpose of the stormwater treatment system is to reduce transportation -related constituent concentrations currently discharged to Big Canyon Creek during storm events and to attenuate stormwater peak -flow discharge rates from the contributing Jamboree Road drainage area. The transportation -related pollutants are currently conveyed to the receiving waters in Big Canyon Creek from a variety of sources, including vehicles, road maintenance, maintenance facility runoff, and landscaping maintenance. Vehicles are known to produce a variety of pollutants that can have a negative impact on water quality in the receiving waters to which they drain. Metals such as copper and zinc can build up on road surfaces through brake and tire wear; other metals such as cadmium, chromium and sometimes lead can be deposited on road surfaces from paint on vehicles and streets. Metals often bind to sediments, trash, and debris on road surfaces; these can be carried into waterways during storm events. In addition to pollutants associated with vehicles, landscaped areas associated with or adjacent to streets (e.g., median, parkway, and residential landscaping) can be sources of pollutants such as pesticides, nutrients (particularly nitrate and phosphorus), and fecal -indicator bacteria (all of which are known to be associated with urban landscaping, which is found throughout the 11.1 -acre Jamboree Road drainage area). These pollutants can be transported to receiving waters during storm events. Finally, in addition to direct deposition to the road surface, street surfaces and adjacent walkways and landscaped areas can be impacted from vehicle emissions through atmospheric deposition of pollutants such as the dissolved fraction of metals and organics (e.g., polynuclear aromatic hydrocarbons (PAHs). According to national and regional best management practices (BMPs) manuals (e.g., the California Stormwater Quality Association BMP handbook), the technology proposed in the stormwater treatment system has been shown to be effective in treating a variety of pollutants associated with transportation runoff, including trash, sediment (and attached pollutants), nutrients and organics such as PAHs and pesticides, and fecal -indicator bacteria. The stormwater treatment system would consist of a primary Stormwater treatment structure and a bioretention cell, as described below. Primary Stormwater Treatment Structure A primary treatment structure would be constructed to receive runoff from existing stormwater inlets serving Jamboree Road. The contributing drainage area draining to the primary stormwater treatment structure is approximately 11.1 acres. The purpose of this structure is to trap, contain, and pretreat trash, total suspended solids (TSS), and free oils prior to conveyance to the bioretention cell. Located adjacent to Jamboree Road, the primary Stormwater treatment structure Big Canyon Habitat Restoration and Water Quality Improvement Project 2-18 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist would be approximately 40 square feet in size and include three chambers. The first chamber would be designed to collect dense solids and trash (floatables); the second would collect sediment and finer solids; and the third would provide storage and delivery of dissolved phase constituents to the bioretention cell. Manhole access ports would be installed for periodic removal of trash and sediment from the three chambers. Bioretention Cell The bioretention cell is an underground, modified constructed wetland that would be designed specifically to treat the suite of transportation -related pollutants found in urban watersheds. The bioretention cell would be constructed to treat stormwater flows that discharge from the primary stormwater treatment structure. The surface area of the bioretention cell would be approximately 0.47 acres in size when measured at the top of the bioretention cell berm (see Figure 5). The bioretention cell would be designed to capture and treat the stormwater that discharges from Jamboree Road. It will treat approximately 0.75 inches of stormwater in a 24-hour period. The bioretention cell will attenuate and reduce the peak discharge rate to Big Canyon Creek during storm events. The bioretention cell will consist of (from top to bottom) layers of soil, sand, and gravel, underlain by an impermeable liner. The top of the cell will be planted with native vegetation. The soil layer would be approximately 2 to 3 feet thick and would be underlain by a 6 -inch sand filter bed located between the bioretention soil and drainage gravel layer situated in the bottom of the bioretention cell. The bottom 12 -inch gravel drainage layer will form the base layer of the bioretention cell and will be underlain by a geotextile cushion. The entire bioretention cell will be underlain by a 60 -MIL high-density polyethylene (HDPE) liner. The bioretention cell would be divided into two subcells, hydraulically separated from one another by an impermeable barrier, to enable the comparison of water quality effluent between the cells. One subcell would be designed to be free draining and the second subcell would be designed such that approximately 12 inches of treated water would remain on the liner and within the gravel drainage layer. Stormwater will flow via gravity from the primary stormwater treatment structure to the top of the subcells through a series of perforated and solid inflow PVC pipes. Pollutants would be removed from stormwater as it flows down through the treatment media. Treated water would flow from the bottom of the bioretention cell through a series of PVC pipes into a newly created wetland habitat area located to the south of the bioretention cell (see Figure 5). The wetland habitat area will be graded to allow for infiltration to groundwater and for surface flow return to Big Canyon Creek. The ,groundwater level in the piezometer in the vicinity of the bio -retention cell is deeper than found at the other piezometers. Given the stratigraphy of the area, the Jamboree Road seeps are not a likely source to this area. Interactions between the deep groundwater and the biofiltration unit are not expected. Water quality monitoring of the bioretention cell and created wetlands are planned and is defined in the Water Quality Monitoring Plan that will be submitted prior to final permit approval.

The interior of the bioretention cell will be periodically maintained, per the approved Operation and Maintenance Plan. This may include the cleanout of vegetation or replacement of soil to ensure continued water quality improvement. 2.4.2.2 Selenium Reduction Measures in Dry Weather Flows (Dry Weather and Seeps / Collection and Diversions) Dry Weather Flow Diversion The purpose of the dry weather flow diversion is to limit the contact between dry weather flows with low selenium concentrations with groundwater seepage flows that contain much higher selenium concentrations. Monitoring investigations conducted by the City in 2015 determined that seepage flows with high selenium concentrations occur in the creek on the east side of Jamboree Road between the proposed diversion and the entrance to the existing culvert. High selenium seeps also occur on the west side of Jamboree Road just downstream of the mouth of the existing culvert (City of Newport Beach 2015, unpublished data). The proposed project proposes to passively collect these high selenium concentration seeps and direct them to the sanitary sewer. The estimated seepage flows are anticipated to be less than 10% of the total current dry weather flows in Big Canyon Creek. Therefore, approximately 90% of the current dry weather flows will be returned to the creek. Diverting the high selenium seepage flows will substantially reduce in -stream selenium concentrations in the downstream creek flowing through the restoration area. No significant impact is expected to the riparian habitat within the section of the creek between the diversion and the returned cleaner dry weather flows as groundwater Big Canyon Habitat Restoration and Water Quality Improvement Project 2-20 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist seepage will sustain the willow vegetation and planned invasive removal and revegetation will further enhance this section of the creek to the east of the culvert under Jamboree Road. Dry weather flows with lower selenium concentrations will be diverted in a new diversion structure located on the Big Canyon Golf Course. The diversion structure will divert about 0.5 cfs and allow higher flows to pass through the diversion structure. The diversion flow line will include a valve that will enable the diverted flows to be reduced and adjusted if necessary. The diversion line will flow via gravity and will be installed along the existing southern slope of the ditch north of the golf course maintenance yard. No grading and soil disturbance is anticipated. The diversion line will be at grade on the surface of the slope and will be anchored to the slope using an anchorage system. The anchor system will be installed along the existing disturbed top of slope adjacent to the golf course maintenance yard fence. The diversion line will transition from the slope into the east side of the Jamboree Road existing culvert. The diversion line will be installed inside the existing Jamboree Road culvert and inside the new culvert extension. The diversion line will discharge dry weather flows into the restored floodplain as shown in Figure 5, to provide surface water to that area. Numerous studies and assessments on selenium loads and sources in Big Canyon Creek have been conducted. Reeder (2011) provided a comprehensive assessment of the geology, hydrology, and water quality related to selenium sources in the watershed from studies conducted as early as the 1970s through 2011. Since then, additional studies have been conducted in the watershed on flow rates (Weston 2013), water balance in the upper watershed (DBS&A 2015), and specific selenium source identification assessments in the lower portion of the watershed (City of Newport Beach, unpublished data). Based on long-term monitoring conducted in 2012 (Weston 2013), the approximate base dry weather flow rate of Big Canyon Creek at Jamboree Road is 0.420 cfs. The proposed dry weather flow diversion upstream of Jamboree Road is not anticipated to impact the natural creek function. It will divert lower selenium water around a stream reach of approximately 170 feet just upstream of Jamboree Road (Figure 5) where higher selenium groundwater seeps have been identified (City of Newport Beach, unpublished data). Groundwater originating in this reach is estimated to contribute less than ten percent of the dry weather baseline flow in the creek, which will be diverted to sanitary sewer. The wet weather function of the creek will not be affected by the dry weather flow diversion. To support the design of the culvert extension and stilling basin, wet weather design discharge rates were determined. The Big Canyon Watershed drains approximately 1,062 acres. The modeled 100 -year flow rate is approximately 2,510 cfs. The 10 -year flow rate is 1,680 cfs and the 2 -year flow rate 1,260 cfs. Big Canyon Habitat Restoration and Water Quality Improvement Project 2-21 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist The diversion line may be extended to the bio -infiltration cell (if slopes allow) to enable irrigation of native vegetation on the surface of the bioretention cell during the plant establishment period and for persistence of the vegetation. If this diverted water is used for irrigation, the potential for accumulation of selenium in the bioretention cell that would not otherwise be addressed through the basin's maintenance program will be assessed through the proposed water quality monitoring program that is described in the Water Quality Monitoring Plan to be provided prior to final permit approval. The project will install a potable line to provide an alternative source of water if that should be required. Seep Water Flow Collection and Diversion Seeps containing higher concentrations of selenium have been observed along the north and south banks along a 170 -foot reach of the creek on the east side of Jamboree Road near the existing culvert (City of Newport Beach, unpublished data). The seep flows will drain through the existing culvert and the new culvert extension and collect in a low point in the bottom the stilling basin floor. As the seep water collects and pools, it will then spill over into vertical open topped risers or similar system and drain into the OCSD sewer. The design will enable sediment to settle out and collect in the stilling basin floor while allowing the seep water to discharge to the sewer. The seep water diversion system will be designed such that the system can be shut off prior to precipitation events. The seep water diversion system will be designed such that the pooled water in the stilling basin floor is limited in extent to minimize mosquito vector habitat, and does not provide an attraction to birds or habitat for fish that would then be exposed to the higher selenium concentrations. Seepage containing high concentrations of selenium is also indicated based on water quality results, immediately downstream of the existing culvert on the west side of Jamboree Road. In order to address this source of high selenium in this area that corresponds to the new culvert extension and stilling pool, seeps will be passively collected and diverted via gravity to the OCSD sewer. Seepage that would otherwise discharge into the creek will be intercepted and collected from the gravel layer that forms the bedding material for the new concrete box culvert extension and the bedding material for the bottom of the concrete stilling basin. Perforated HDPE collection pipes will be installed in the gravel bedding material to convey water to a flow metering structure prior to discharge to the OCSD sanitary sewer. The seepage flow into the sewer is anticipated to be intermittent and the flow is rate anticipated to be low (in the 0-10 gpm range) due to the relatively low permeability of the soil in this area. The seepage collection lines include a valve to enable the collected flow to the OCSD sanitary sewer to be controlled. If the flow rate is higher than anticipated, the flow will likely be reduced through coordination with OCSD. 2.4.3 Infrastructure Improvements 2.4.3.1 Orange County Sanitation District Access Road and Dosing Facility The Project will also be constructed in coordination with infrastructure improvements requested by the Orange County Sanitation District (OCSD) that include the extension and improvement of Big Canyon Habitat Restoration and Water Quality Improvement Project 2-22 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist the existing access road along the toe of slope along the west side of Jamboree Road and the construction a dosing station for odor control. A 12 -foot wide gravel roadway would be constructed to facilitate access to three OCSD manholes including a manhole located to the north of the existing culvert outfall. To provide access to this manhole, the existing culvert beneath Jamboree Road will be extended approximately 75 feet and an access roadway will be constructed on top of the culvert. The new gravel road would parallel Jamboree Road and connect to the existing gravel access road on the south end of the site. The gravel access road will also serve as pedestrian trail which is consistent with existing gravel roads in Big Canyon to serve the dual purpose of manhole access and pedestrian trails. The culvert extension will include a concrete stilling basin at the end of the culvert extension. The purpose of the stilling basin is to dissipate hydraulic energy during wet weather storm flow events. The stilling basin will be constructed with reinforced concrete and will include a concrete access ramp to enable access for maintenance. Maintenance activities will include sediment and debris removal from the stilling basin during dry weather. An automatic chemical -dosing station would be constructed near the beginning of the access road extension. The dosing station consists of a 12 -foot high tower, 8 -foot diameter that would be constructed on a 20 -foot by 20 -foot pad, and a gravel access road as needed to access the station. Native plants will be planted around the facility. The station would be maintained on a monthly basis. A vehicle access path that doubles as the hiking trail would be constructed as a part of the proposed project to provide maintenance access to the infrastructure improvement components. 2.4.3.2 Community Access Improvements and Educational Opportunities Public access to the project site and surrounding environs is currently provided by existing hiking paths in Big Canyon Nature Park. The project includes providing improved and new trails for public access both on the north and south side of the creek. This new trail will allow for educational opportunities regarding water quality and creek restoration activities while keeping trails out of sensitive habitats and restored and enhanced riparian corridors. Preliminary public access and walkway signage and locations has been developed from previous efforts and will be incorporated in this project. The proposed OCSD access road will serve to connect the existing gravel path over the creek to connect with an improved trail on the north side of the creek. In addition, a bicycle path connector has been incorporated into this design to allow for direct access from Jamboree Road. Interpretive elements include key features such as a viewing area on the bio retention cell maintenance road, and informational signage. This plan is consistent with on-going efforts planned for the Big Canyon Watershed in consultation with the City, environmental organizations including the Newport Bay Conservancy and Irvine Ranch Conservancy, and the appropriate regulatory agencies. Big Canyon Habitat Restoration and Water Quality Improvement Project 2-23 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist 2.5 Construction Activities and Schedule Project construction is expected to begin in Fall 2016 and will include the infrastructure components of the project, habitat restoration, and habitat mitigation implementation. Construction will be complete by March 31, 2017 to avoid impacts during the nesting season. Planting of all restoration and mitigation areas will take place once grading has been completed (see Table 2-2). Construction activities would commence with the installation of construction stormwater pollution prevention BMPs in accordance with the project Stormwater Pollution Prevention Plan (SWPPP). Following the installation of stormwater BMPs, project construction work would occur in phases for a duration of five to six months. The following schedule presents the construction phases, the activities to be completed under each phase, and the duration of the activities. Several activities will run concurrently to achieve the overall construction schedule of approximately five months. Phase Activity Duration Month 1 Month 2 Month 3 Month 4 Month 5 Mobilization & Site preparation 1-2 weeks Earthwork clearing & grubbing Excavation and 2-3 weeks grading Drainage Culvert extension 4-6 weeks Structures and Piping Construction Dry weather diversion structures and external 2-3 weeks piping Water Quality Bioretention cell liner 1-2 weeks System and piping Construction Bioretention cell media 1-2 weeks placement Bioengineering 1-2 weeks structure construction OCSD Scope OCSD dosing station 4-6 weeks installation Restoration Site vegetation 3-4 weeks FF11111111111 restoration 11 Approximately 5 acres would be disturbed during project construction. Earthwork cuts are anticipated from the widened floodplain downstream and from the south bank of the Big Canyon Creek and the wetland habitat area. The total earthwork cut volume is approximately 4,000 cubic yards. Earthwork fills are anticipated for the bioretention cell berms and OCSD access road. The anticipated fill volume for mass earthwork is approximately 8,000 cubic yards. The net total volume import (soil and bioretention cell media) is approximately 4,000 cubic yards. Haul trucks would be used to transport earthen material used to construct the project. These haul trucks would access the site from the intersection of San Joaquin Road and Jamboree Road west on San Joaquin Road to Back Bay Drive, and then travel north on Back Bay Drive to the Big Big Canyon Habitat Restoration and Water Quality Improvement Project 2-24 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist Canyon Trail maintenance road entrance. Trucks would follow the maintenance road east to the construction staging area as shown in Figure 5. It is estimated that approximately 40 daily haul truck trips and up to 900 to 1,000 total haul truck trips for material deliveries would occur over the course of construction. Approximately eight employees would be present on the project site at any given time during construction, including a construction superintendent, up to two laborers, up to three equipment operators, and up to two haul truck drivers. Typical equipment required for construction of the project would include a loader, back hoe, dozer, compactor, chipper (mulch), haul trucks, and a water truck. Construction is expected to occur between the hours of 7:00 a.m. and 6:30 p.m. Monday through Friday and 8:00 a.m. and 6:00 p.m. on Saturdays as set forth in the City of Newport Beach's Municipal Code 10.28.040, Construction Activity — Noise Regulations. No construction would occur on Sundays or federal holidays. Construction activities will be coordinated with erosion control and surface water diversion to prevent soils loss, channel instability, discontinuity of water supply during dry weather season, and flood damages during major wet season events. A Water Quality Management Plan (WQMP) will be developed as part of the Construction SWPPP to be implemented from the onset of the construction to post construction. Biologically sensitive area protection will be established prior to construction and periodically monitored. Water quality protection during construction will be monitored based on a pre - construction Quality Assurance Project Plan (QAPP) and Sampling and Analysis Plan (SAP), to be developed prior to construction.

Environmental Checklist 2.6 Project Operation and Maintenance Within the bioretention cell, sediment removal is expected only after major rainfall events. Maintenance is critical if stormwater wetland basins are to function as originally designed. A specific maintenance plan will be developed for the bioretention cell when the final design has been completed, outlining the schedule and scope of maintenance operations, as well as the documentation and reporting requirements. The following are general maintenance requirements: 1. The stormwater wetland basin should be inspected annually and inspections after major storm events are encouraged (wetland basin inspection and maintenance checklists will be developed specifically for the bioretention cell). Trash and debris should be removed as needed, but at least annually prior to the beginning of the wet season. 2. Site vegetation should be maintained as frequently as necessary to maintain the aesthetic appearance of the site and to prevent clogging of outlets, creation of dead volumes, and barriers to mosquito fish to access pooled areas, and as follows: • Vegetation, large shrubs, or trees that limit access or interfere with basin operation should be pruned or removed. • Slope areas that have become bare should be revegetated and eroded areas should be regraded prior to being revegetated. • Invasive vegetation, such as Alligatorweed (Alternanthera philoxeroides), Halogeton (Halogeton glomeratus), Spotted Knapweed (Centaurea maculosa), Giant Reed (Arundo donax), Castor Bean (Ricinus communis), Perennial Pepperweed (Lepidium latifolium), and Yellow Starthistle (Centaurea solstitialis) must be removed and replaced with noninvasive species. Invasive species should never contribute more than 25% of the vegetated area. • Dead vegetation should be removed if it exceeds 10% of area coverage. This does not include seasonal die -back where roots would grow back later in colder areas. Vegetation should be replaced immediately to maintain cover density and control erosion where soils are exposed. 3. Sediment buildup exceeding 6 inches over the storage capacity in the first cell should be removed. Sediments should be tested for toxic substance accumulation in compliance with current disposal requirements visual or olfactory indications of pollution are noticed. If toxic substances are encountered at concentrations exceeding thresholds of Title 22, Section 66261 of the California Code of Regulations, the sediment must be disposed of in a hazardous waste landfill. 4. Following sediment removal activities, replanting and/or reseeding of vegetation may be required for reestablishment. Routine maintenance will be performed to keep the bioretention cell piping, diversion piping, and seep water inlets clear of debris and sediments. Erosion control materials for embankment and slope protection will be inspected routinely and repaired or replaced, as necessary. Routine Big Canyon Habitat Restoration and Water Quality Improvement Project 2-26 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist maintenance of the diversion structures and stilling pool will be required on a regular basis to keep them clear of sediment and debris accumulations. Upon initial installation, maintenance could occur as frequently as once per month, and could include a visual check, debris clearing, and/or equipment repair. Semiannual inspections for beginning and end of the wet season will be scheduled to identify any erosion problems and remove debris and sediment accumulation. A large rain event may require additional visual inspections to clear debris. The additional visual inspections may also require evaluation of wetland vegetation and inspection of vector presence or habitats on the project site. Inspections will include water quality BMPs at the storm outlets for erosion protection. Additionally, BMPs involving filtration functions will be inspected to ensure their pollutant reduction efficiency. Operation of the bioretention cell would be passive for the most part, requiring occasional inspections to confirm the treatment cells are operating as intended by the design. As a part of the proposed project, a comprehensive Operations and Maintenance Plan has be developed (see Appendix A). The Plan will be updated when the final design for the bioretention cell is complete. 2.7 Project Approvals and Discretionary Actions The City of Newport Beach would use this IS/MND and supporting documentation in its decision to certify this IS/MND and approve the project.

A scenic vista is defined as a viewpoint that provides expansive views of a highly valued landscape for the benefit of the general public. According to the City of Newport Beach General Plan Update EIR, the City does not contain any officially designated scenic vistas; however, public view points are identified within the City. The nearest public view point is located about 1,200 feet west of the project site within the western portion of Big Canyon Park. This public view point provides views of Upper Newport Bay. Project grading and construction activities as well as restoration activities on the project site would not affect views from the nearest public view point because the view point offers views to the west toward Upper Newport Bay, and the project site is located east of the view point. Therefore, implementation of the proposed project would result in no impacts on scenic vistas. b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic building within a state scenic highway? No Impact. There are no officially designated scenic highways within Newport Beach (City of Newport Beach 2006). However, the project area is approximately one mile north of State Route 1 (Pacific Coast Highway), identified by the City as "Eligible for State Scenic Highway" designation. Because no scenic highways are currently designated within the City, implementation of the proposed project would result in no impact to scenic resources within a state- or locally designated scenic highway.

Environmental Checklist C) Substantially degrade the existing visual character or quality of the site and its surroundings? Less than Significant Impact. The construction activities associated with the project would result in changes to the existing visual character of the project site, including construction grading and the removal of existing vegetation. However, as mentioned above, the creek restoration and riparian habitat enhancement component of the project would remove the non-native vegetation and restore native vegetation on the project site. This component of the project would improve the existing visual character and quality of the site by restoring natural habitat conditions in the creek, and thus would result in a less than significant impact to the existing visual quality of the project site. d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? No Impact. The proposed project would create no new source of lighting in the project area, and thus would result in no light impacts. The project includes structural improvements to the culvert and stilling pond, however these features would use earth materials in their construction, and would result in no glare impacts. Thus, the project would result in no adverse effects to day or nighttime views in the area due to light or glare. Resources City of Newport Beach.

Environmental Checklist a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? No Impact. The project vicinity is located in a developed and urbanized area of the city. The project site is located on land designated as Urban and Built -Up Land, as shown on maps prepared pursuant to the Farmland Mapping and Monitoring Program (Department of Conservation 2012). Because the project site does not contain Farmland, the proposed project would not cause direct or indirect impacts related to the conversion of Prime Farmland, Unique Farmland, or Farmland of Statewide Importance. Thus, the project would result in no Farmland conversion impacts. b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? No Impact. A Williamson Act Contract requires private landowners to voluntarily restrict their land to agricultural land and compatible open -space uses. There is no Williamson Act contract in effect for the project site nor does the City have any agriculture -oriented zoning designations or Williamson Act Contract land. Because the project site does not have a Williamson Contract, the project would result in no zoning conflict or Williamson Act contract impacts. C) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Government Code section 51104(g))? No Impact. The project site is zoned as Open Space and is surrounded by lands zoned for residential and industrial uses. The City of Newport Beach does not contain any land zoned as forest land, timberland, or for timberland production. Therefore, the project would result in no forest land or timberland zoning impacts. d) Result in the loss of forest land or conversion of forest land to non -forest use? No Impact. The project site and surrounding area contain no forest land. Thus, implementation of the proposed project would result in no impacts related to the loss or conversion of forest land to non -forest use. e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use or conversion of forest land to non -forest use? No Impact. There are no agricultural uses or forest uses in the vicinity of the project site. Therefore, the proposed project would not involve changes in the existing environment that could result in conversion of Farmland to non-agricultural use or conversion of forest land to non -forest use.

Would the project: a) Conflict with or obstruct implementation of the ❑ ❑ ® E] applicable air quality plan? b) Violate any air quality standard or contribute 1:1 El substantially to an existing or projected air quality violation? c) Result in a cumulatively considerable net increase of E] E] any criteria pollutant for which the project region is non -attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? d) Expose sensitive receptors to substantial pollutant ® El concentrations? e) Create objectionable odors affecting a substantial ❑ ❑ ® El number of people? Discussion a) Conflict with or obstruct implementation of the applicable air quality plan? Less than Significant Impact. A significant air quality impact may occur if a project is not consistent with the applicable Air Quality Management Plan (AQMP) or would in some way obstruct the implementation of the policies or obtainment of the goals of that plan. The proposed project is located within the City of Newport Beach, California. The city is located in the South Coast Air Basin (Basin), which is within the jurisdiction of the South Coast Air Quality Management District (SCAQMD). The SCAQMD is the agency principally responsible for comprehensive air pollution control in the Basin. To that end, the SCAQMD, a regional agency, works directly with the Southern California Association of Governments (SLAG), county transportation commissions, local governments, and cooperates actively with all state and federal government agencies. The SCAQMD develops rules and regulations, establishes permitting requirements, inspects emissions sources, and enforces such measures though educational programs or fines, when necessary. SCAQMD and SCAG are responsible for preparing the AQMP, which addresses federal and state Clean Air Act (CAA) requirements. Pursuant to these requirements, the SCAQMD is required to reduce emissions of criteria pollutants for which the Basin is in non -attainment. The AQMP details goals, policies, and programs for improving air quality in the Basin. The 2012 AQMP is currently the most recent plan for the Basin, and was adopted by the SCAQMD Governing Board on December 7, 2012. The 2012 AQMP was prepared to accommodate growth, to reduce the high levels of pollutants in the Basin, to meet federal and state air quality standards, and to minimize the fiscal impact that pollution control measures have on the local economy. It builds on the approaches taken from the previous 2007 AQMP and sets Big Canyon Habitat Restoration and Water Quality Improvement Project 3-8 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist forth a comprehensive and integrated program that will lead the Basin into compliance with the federal 24-hour PM2.5 air quality standard, and to provide an update to the Basin's commitments towards meeting the federal 8 -hour ozone standards. SLAG, which is the regional metropolitan planning organization for the Southern California area, has established the assumptions for growth, in terms of demographic growth and associated air quality impacts, and these assumptions are utilized in SCAQMD's AQMP. Since the forecasted growth in SCAQMD's AQMP for the Basin relies on SCAG's regional growth forecasts, and because SCAG's growth forecasts are based upon, among other things, land uses specified in city general plans, a project that is consistent with the land use designated in a city's general plan would also be consistent with the AQMP growth projections. As discussed in Chapter 2 (Project Description), the proposed project would improve water quality through water conservation, runoff reduction and restoration. Specifically, the proposed project would include a wetland that would treat both dry and wet weather flows in Big Canyon, and would eliminate the storm drain -associated vector habitat. The proposed project would contain a pump station, and a primary treatment structure. Given that the proposed project is an infrastructure project that serves only to treat contaminated water and improve the functionality of the wetland; implementation of the proposed project would not result in any additional population or housing growth in the project area that has not been accounted for in the City of Newport Beach General Plan. Consequently, as no growth -inducing development or land use would occur under the project, implementation of the project would not conflict with or obstruct the implementation of SCAQMD's AQMP. In addition, SCAQMD regional significance thresholds were designed to assist SCAQMD in determining if a project would worsen air quality conditions in the Basin. The determination of AQMP consistency is primarily concerned with the long-term influence of the proposed project on air quality in the Basin. As discussed under Question 3(b) below, the proposed project would not result in significant regional construction emissions and would not interfere with the attainment of air quality standards. Thus, the project's construction activities would not conflict with or obstruct implementation of the AQMP. Overall, the proposed project would result in a less than significant impact related to the AQMP. b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? Less than Significant Impact. A project may have a significant impact where project -related emissions would exceed federal, state, or regional standards or thresholds, or where project - related emissions would substantially contribute to an existing or projected air quality violation. As the proposed project consists of the installation of a surface water treatment system, culvert improvement and restoration activities, potential air quality impacts associated with the project would only occur during the construction phase as the operation of construction equipment would result in additional air emissions in the region. Once construction activities have been completed, operation of the proposed project would not involve any direct pollutant emissions sources onsite. In addition, vehicle emissions would be generated by worker trips to and from the project area for routine maintenance of the dosing station, including removal of sediment and debris from the stilling basin. These maintenance trips are anticipated to occur only once a month. As such, the Big Canyon Habitat Restoration and Water Quality Improvement Project 3-9 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist mobile emissions generated during project operations would be negligible as discussed below under Question 3(c). Construction of the proposed project is expected to last approximately five months and is tentatively scheduled to begin in September 2016 and continue through January 2017. Construction activities would commence with site preparation and clearance (approximately 2 weeks), followed by excavation and grading (approximately five weeks); culvert extension (6 weeks); dry weather diversion structures and external piping (2 weeks), construction of bioretention cell liner and piping (2 weeks), bioretention cell media placement (2 weeks), bioengineering structure construction (2 weeks), OCSD dosing station installation (6 weeks) and site vegetation restoration (4 weeks). Several of these activities will run concurrently to achieve the overall construction schedule of approximately five months. Criteria air pollutants are defined as pollutants for which the federal and state governments have established ambient air quality standards for outdoor concentrations to protect public health. These standards are designed to protect the most sensitive persons from illness or discomfort. Pollutants of concern include carbon monoxide (CO), nitrous oxides (NOx), particulate matter that is 10 microns or less in diameter and 2.5 microns or less in diameter (PMIo and PM2.5), sulfur oxides (SOx), and reactive organic gasses (ROG). Construction activities associated with the project involving site preparation and excavation would primarily generate respirable particulate matter (PMIo) emissions. Mobile source emissions (use of diesel -fueled equipment onsite, and traveling to and from the construction site) would primarily generate oxides of nitrogen (NOx) emissions. The amount of emissions generated on a daily basis would vary, depending on the amount and types of construction activities occurring at the same time. It is mandatory for all construction projects in the Basin to comply with SCAQMD Rule 403 (Fugitive Dust) for controlling fugitive dust emissions. Specific Rule 403 control requirements include, but are not limited to, applying water in sufficient quantities to prevent the generation of visible dust plumes, applying soil binders to uncovered areas, reestablishing ground cover as quickly as possible, and maintaining effective cover over exposed areas. Site watering and application of soil binders would reduce the particulate matter from becoming airborne, while washing of transport vehicle tires and undercarriages would reduce re -entrainment of construction dust onto the local roadway network. The analysis of daily construction emissions has been prepared utilizing the California Emissions Estimator Model (CalEEMod). CalEEMod was used to determine whether short-term construction -related emissions of criteria air pollutants associated with the proposed project would exceed SCAQMD's applicable regional thresholds and where mitigation would be required. Modeling was based on project -specific data, when available. Where project -specific information was not available, default model settings were used to estimate criteria air pollutant and ozone precursor emissions. For the purpose of this analysis, the construction emissions occurring on a peak (worst-case) day over the entire project construction period were estimated and evaluated against the applicable SCAQMD significance thresholds. The daily emissions that are estimated to occur on peak construction days for each construction phase of the proposed project are shown in Table 3-1. These calculations take into account that Big Canyon Habitat Restoration and Water Quality Improvement Project 3-10 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist appropriate dust control measures under SCAQMD Rule 403 would be implemented by the project during each phase of construction.

SOURCE: ESA, 2016 Big Canyon Habitat Restoration and Water Quality Improvement Project 3-12 ESA / Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist As shown in Table 3-1 and Table 3-2, the peak daily regional emissions generated during project construction for individual phases, as well as those that overlap, would not exceed the SCAQMD daily significance thresholds for ROG, NOx, CO, SOX, PM2.5 and PMIo. Since construction emissions would not exceed the SCAQMD thresholds, the regional impacts related to air quality during project construction activities would be less than significant. C) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non -attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? Less than Significant Impact. With respect to air quality, a significant impact may occur if the project would add a considerable cumulative contribution to federal or state non -attainment pollutants. Because the Basin is currently classified as a state nonattainment area for ozone, PMIo, and PM2.5i cumulative development consisting of the proposed project along with other reasonably foreseeable future projects in the Basin as a whole could violate an air quality standard or contribute to an existing or projected air quality violation. With respect to determining the significance of the proposed project's contribution to regional emissions, the SCAQMD neither recommends quantified analyses of cumulative construction emissions nor provides methodologies or thresholds of significance to be used to assess cumulative construction impacts. Instead, the SCAQMD recommends that a project's potential contribution to cumulative impacts should be assessed utilizing the same significance criteria as those for project specific impacts. Furthermore, SCAQMD states that if an individual development project generates less than significant construction or operational emissions then the development project would not generate a cumulatively considerable increase in emissions for those pollutants for which the Basin is in nonattainment. As discussed under Question 3(b) above, the proposed project would not generate construction emissions that would exceed the SCAQMD's recommended thresholds. Once construction activities have been completed, operation of the proposed project would not involve any direct pollutant emissions sources onsite. In addition, because mobile emissions generated from worker trips to and from the project area for routine maintenance of the treatment structures are anticipated to only occur once a month, the mobile emissions generated would be negligible. As such, project operations would not generate substantial pollutant emissions that would exceed SCAQMD's applicable regional thresholds. Therefore, the proposed project would not generate a cumulatively considerable increase in emissions of the pollutants for which the Basin is in nonattainment, and impacts would be less than significant. d) Expose sensitive receptors to substantial pollutant concentrations? Less than Significant Impact. A significant impact may occur if a project were to generate pollutant concentrations to a degree that would significantly affect sensitive receptors. Sensitive receptors are populations that are more susceptible to the effects of air pollution than are the population at large. The SCAQMD identifies the following as sensitive receptors: long-term health care facilities, rehabilitation centers, convalescent centers, retirement homes, residences, Big Canyon Habitat Restoration and Water Quality Improvement Project 3-13 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist schools, playgrounds, child care centers, and athletic facilities. The nearest and most notable off- site sensitive receptors to the project would be the existing residential uses located approximately 46 feet northeast of the project site. Localized Construction Emissions Emissions from construction activities have the potential to generate localized emissions that may expose sensitive receptors to harmful pollutant concentrations. The SCAQMD has developed localized significance thresholds (LSTs) that are based on the amount of pounds of emissions per day that can be generated by a project that would cause or contribute to adverse localized air quality impacts. These localized thresholds, which are found in the mass rate look -up tables in the Final Localized Significance Threshold Methodology document prepared by the SCAQMD, apply to projects that are less than or equal to five acres in size and are only applicable to a project's on- site emissions for the following criteria pollutants: NOx, CO, PMIo, and PM2.5. LSTs represent the maximum emissions from a project that are not expected to cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standards, and are developed based on the ambient concentrations of that pollutant for each source receptor area (SRA) within the Basin. The project area, which consists of an approximately 5 acres, is located in the City of Newport Beach (SRA 18). The LSTs developed by SCAQMD are provided for the following distances from the source of emissions: 25 meters, 50 meters, 100 meters, 200 meters, and 500 meters. Additionally, the LSTs at these distances also vary based on the size of the project site. The SCAQMD has provided LSTs for sites that are 1 -acre, 2 -acre, and 5 -acre in size. As the total construction work area would be approximately 5 acres, the LSTs for a five -acre site is used for this analysis. The nearest and most notable off-site sensitive receptors that could potentially be subject to localized air quality impacts associated with construction of the proposed project would be the existing residential uses located approximately 45 feet northeast of the project site. Given the proximity of these sensitive uses to the construction areas where the surface water treatment system would be installed, the LSTs for a five -acre site with receptors located within 25 meters (82.02 feet) are used to address the potential localized air quality impacts associated with the project's construction -related NOx, CO, PMIo, and PM2.5 emissions.I As discussed in Question 3(b) above, it was determined that a worst-case construction day for the proposed project would include emissions from the entire 5 -acre construction site. However, whereas the construction emissions analysis conducted under Question 3(b) pertained to the project's total daily mass emissions, the LST analysis is concerned with a project's localized air quality impacts. The peak daily emissions generated during construction activities were estimated using CalEEMod and are shown in Table 3-3. As LSTs are only concerned with a project's on-site t Although the existing sensitive uses (i.e., residential uses) located northeast of the project site would be located closer than 25 meters from the project's construction areas, the SCAQMD's LST methodology indicates that projects with boundaries located closer than 25 meters to the nearest receptor should use the LSTs for receptors located at 25 meters.

Environmental Checklist As shown in Tables 3-3 and 3-4, the peak daily emissions generated during project construction activities would not exceed the applicable construction LSTs. Therefore, localized air quality impacts from the project's construction activities on the surrounding off-site sensitive receptors would be less than significant. Localized Traffic -Related Emissions Construction of the proposed surface water treatment system is not anticipated to result in substantial air quality impacts to the public with respect to traffic congestion. The proposed project limits the construction trips to distinct roads. Haul trucks would access the site from the intersection of San Joaquin Road and Jamboree Road west on San Joaquin Road to Back Bay Drive, and then travel north on Back Bay Drive to the Big Canyon Trail maintenance road entrance. Trucks would follow the maintenance road east to the construction staging area. It is estimated that approximately 20 daily haul truck trips and up to 1,000 total haul truck trips for material deliveries would occur over the course of construction. No work is expected to occur within city streets. Overall, the proposed project would result in a less than significant impact related to localized, traffic -related pollutant concentrations during construction. Toxic Air Contaminants A substance is considered toxic if it has the potential to cause adverse health effects in humans. A toxic substance released into the air is considered a toxic air contaminant (TAC). TACs are identified by state and federal agencies based on a review of available scientific evidence. In the State of California, TACs are identified through a two-step process that was established in 1983 under the Toxic Air Contaminant Identification and Control Act. This two-step process of risk identification and risk management was designed to protect residents from the health effects of toxic substances in the air. Construction of the proposed project would result in short-term diesel exhaust emissions from off-road heavy-duty equipment. Diesel exhaust is considered a TAC. Construction would result in the generation of diesel exhaust emissions from the use of off-road diesel equipment required for site preparation and excavation, and other construction activities. The dose to which sensitive receptors are exposed is the primary factor used to determine health risk. Dose is a function of the concentration of a substance or substances in the environment and the extent of exposure that person has with the substance. Dose is positively correlated with time, meaning that a longer exposure period would result in a higher exposure level for the maximally exposed individual. Thus, the risks estimated for a maximally exposed individual are higher if a fixed exposure occurs over a longer period of time. According to the Office of Environmental Health Hazard Assessment (OEHHA), health risk assessments, which determine the exposure of sensitive receptors to toxic emissions, should be based on a 70 -year exposure period; however, such assessments should be limited to the period/duration of activities associated with the proposed project. Construction of the entire project would occur over approximately a five month period, and would be separated into 9 different phases. As such, the project's construction activities would not be permanently stationed at any one location but instead would occur at different locations depending on the phase. Thus, the duration of the proposed construction Big Canyon Habitat Restoration and Water Quality Improvement Project 3-16 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist activities at any one site would only constitute a small percentage of the total 70 -year exposure period. Thus, diesel particulates from construction activities would not be anticipated to result in the exposure of sensitive receptors to levels that exceed applicable standards, and impacts would be less than significant. e) Create objectionable odors affecting a substantial number of people? Less than Significant Impact. A significant impact may occur if objectionable odors occur which would adversely impact sensitive receptors. According to the SCAQMD CEQA Air Quality Handbook, land uses associated with odor complaints typically include agricultural uses, wastewater treatment plants, food processing plants, chemical plants, composting, refineries, landfills, dairies, and fiberglass molding. As the proposed project consists of the installation of infrastructure for the treatment of water and restoration of the surrounding area, the proposed project is not a type of use identified by the SCAQMD as being associated with odors. Thus, the proposed project would not result in objectionable odors during operations, and this impact would be less than significant. During construction of the proposed project, exhaust from equipment may produce discernible odors typical of most construction sites. Such odors would be a temporary source of nuisance to adjacent uses, but would not affect a substantial number of people. As odors associated with project construction would be temporary and intermittent in nature, the odors would not be considered to be a significant environmental impact. Therefore, impacts associated with objectionable odors would be less than significant.

Discussion The following evaluation is a summary of the findings provided in the Biological Resources Technical Report prepared by ESA in January 2016. This report is provided in Appendix C. a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? Less than Significant with Mitigation Incorporated. No plant or wildlife species listed as state or federally threatened, endangered, or candidate species was observed within the project area, and no US Fish and Wildlife Service (USFWS)-designated Critical Habitat occurs onsite. Therefore, the project would not affect state or federally listed species or USFWS Critical Habitat. Big Canyon Habitat Restoration and Water Quality Improvement Project 3-18 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist No species covered by the Orange County Central -Coastal Natural Community Conservation Plan/Habitat Conservation Plan (NCCP/HCP) were identified in the project area; therefore, the project would not affect species covered by the Orange County Central -Coastal NCCP/HCP. Three California Species of Special Concern were observed within the riparian forest habitat onsite, including yellow warbler, yellow -breasted chat, and Cooper's hawk. These species, as well as other bird species nesting in the riparian or adjacent upland habitat or in the ornamental trees just outside of the project boundary could be negatively affected by the project through temporary loss of habitat during invasive species removal, floodplain grading, replanting, and construction of water quality, infrastructure and recreational facilities. Indirect impacts from construction (e.g., noise and increased activity) could also affect nesting bird species during the breeding season by disrupting breeding behavior, resulting in nest abandonment and loss of productivity. These potential impacts to nesting birds and vegetation communities would be considered significant. Mitigation Measures BI0-1: Nesting Birds. Impacts to nesting birds would be avoided by conducting all grading and construction activities outside of the bird breeding season (February 1—August 15). If breeding season cannot be avoided, the following measures would be followed. a. During the avian breeding season, a qualified Project Biologist shall conduct a preconstruction avian nesting survey no more than 10 days prior to vegetation disturbance or site clearing. If grading or other construction activity begins in the non - breeding season and proceeds continuously into the breeding season, no surveys shall be required. However, if there is a break of 10 days or more in grading or construction activities during the breeding season, a new nesting bird survey shall be conducted before these activities begin again. b. The nest survey shall cover all reasonably potential nesting locations on and within 300 feet of the proposed construction activities areas. c. If an active nest is found during an avian nest survey, a qualified Project Biologist shall implement a 300 -foot minimum avoidance buffer for coastal California gnatcatcher, least Bell's vireo, and other passerine birds and a 500 -foot minimum avoidance buffer for all raptor species. Buffer distances for other species would be determined by the Project Biologist based on the species and its breeding or nesting requirements. The nest site area shall not be disturbed until the nest becomes inactive or the young have fledged. During clearing, Grubbing, and excavation activities, the nest will be monitored by qualified biologist for the duration of these activities, or until the nestlings have fledged. Daily monitoring may be required, however, the frequency of nest monitoring will be determined by the biologist based on the species and level of activity in the project area. Big Canyon Habitat Restoration and Water Quality Improvement Project 3-19 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist BI0-2: Vegetation Communities. The project would impact a total of 2.46 acres of southern riparian forest, and 0.50 acre of coastal sage scrub. These vegetation communities are both highly disturbed from a heavy infestation of non-native plants and compacted, saline soils. These low - quality habitats would be restored to provide habitats with much greater ecological function than the current conditions. A total of 2.46 acres of southern riparian forest would be mitigated onsite through substantial habitat restoration (2.03 acres), willow riparian forest habitat creation (0.25 acre), and riparian habitat enhancement (0.64 acre). Impacts to coastal sage scrub would be mitigated onsite through restoration of 1.85 acres, which is 1.35 acres in excess of the required 1:1 ratio. Impacts to non-native grassland, disturbed areas, and ornamental vegetation do not require mitigation (Table 3-5).

SOURCE: ESA, 2016 In addition, as part of the Habitat Restoration Plan, construction and operational Best Management Practices (BMPs) will be implemented to protect trees within the riparian habitat from the Polyl2hagous shot hole borer (PSHB). PSHB is a new insect pest in southern California that drills into trees and carries in a symbiotic fungus, which infests and kills the tree (UCR, Center for Invasive Research 2016). The nearest known infestation is 1 mile east of the project site. This invasive species is potentially devastating to native riparian habitat, as it can attack a variety of native tree species, such as Coast Live Oak (Quercus agri olia), California sycamore (Platanus racemosa), Fremont cottonwood (Populus- remontii), red willow (Salix laevigata), and white alder (Alnus rhombi olia). PSHB attacks a variety of non-native species as well; however, there are no reported incidences of PSHB invading the Brazilian peppertree. In order to ensure that project activities do not result in the spread of PSHB into the project site, the following Best Management Practices will be employ 1. During the tailgate training prior to construction, the onsite workers will be educated about PSHB and its spread; Big Canyon Habitat Restoration and Water Quality Improvement Project 3-20 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist 2. Prior to Peppertree removal, the project area will be surveyed for signs of PSMH; if potential signs are observed, the University of California Cooperative Extension in Orange County (UCCE) and/or University of California, Riverside Eskalen Lab will be notified for confirmation (UCREL). 3. Should PSHB be found in any material that will be cleared and grubbed, the material shall be chipped to <1" and disposed of in an approved landfill. Other remediation actions will be discussed with UCCE or UCREL. 4. To reduce the spread of the beetle or fungus, all equipment will be disinfected prior to cominiz onsite. Significance after Mitigation Less than Significant. Potential impacts to nesting birds and vegetation communities would be reduced to less than significant with implementation of Mitigation Measures BI0-1 and 13I0-2 described above. b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? Less than Significant with Mitigation Incorporated. The proposed project would permanently impact a total of 1.42 acres due to the implementation of the proposed water quality and infrastructure components and proposed trails. A total of 2.03 acres would be temporarily impacted from the riparian habitat restoration component of the project. An additional 0.90 acres would be temporarily impacted from construction -related activities. The permanent impacts to sensitive vegetation consist of 0.43 acre of southern riparian forest and 0.26 acre of coastal sage scrub (Table 3-6). Additional permanent impacts include 0.63 acre of non-native grassland, 0.08 acre of disturbed habitat, and 0.03 acre of ornamental land cover. The temporary impacts associated with the riparian habitat restoration component consist of primarily (1.77 acres) low - quality southern riparian forest, but also include 0.14 acre of non-native grassland, 0.06 acre of low -quality coastal sage scrub, 0.02 acre of disturbed habitat, and 0.03 acre of ornamental land cover. Restoration of this area would result in much higher quality native willow forest habitat. Note that some areas of the existing southern riparian forest are not considered jurisdictional by the Corps/RWCQB and/or CDFW; therefore, refer to Table 3-7, below for detailed impact acreages of jurisdictional resources. The temporary impacts associated with construction consist of 0.43 acre of non-native grassland, 0.26 acre of low -quality southern riparian forest, 0.18 acre of low -quality coastal sage scrub, and 0.03 are of disturbed habitat. These construction -related temporary impacts include the staging area adjacent to the existing access road on the southwestern portion of the project area, the staging area adjacent to Jamboree road (the 8 -foot centerline of this area would become a permanent trail after infrastructure construction has been completed, but the surrounding slopes would be revegetated), and the slopes surrounding the bioretention cell. These temporary construction impacts would be considered significant.

Significance after Mitigation With implementation of Mitigation Measure 13I0-2, a total of 2.46 acres of southern riparian forest would be mitigated onsite through substantial habitat restoration (2.03 acres), willow riparian forest habitat creation (0.25 acre), and riparian habitat enhancement (0.64 acre). Impacts to coastal sage scrub would be mitigated onsite through restoration of 1.85 acres, which is 1.35 acres in excess of the required 1:1 ratio. Impacts to sensitive vegetation communities would be less than significant after implementation of Mitigation Measure 13I0-2. C) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Less than Significant with Mitigation Incorporated. Avoidance. Based upon previous project planning and input from the resource agencies, infrastructure design measures have been implemented to avoid sensitive habitat and species to the extent practicable. Limitations to avoid the sensitive habitat and species remain due to the presence of two sewer lines that run across the existing riparian habitat and parallel to Jamboree Road. The location of the bioretention cell was placed to not impact future maintenance of either line. The proposed maintenance road/hiking trail has been place outside the jurisdictional wetland limits and crossing of the creek would now occur over the proposed culvert extension, rather than through the middle of the creek, which was the original trail location identified in the previous planning effort. Big Canyon Habitat Restoration and Water Quality Improvement Project 3-22 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist Because of creek degradation, both the mainflow creek bed incision and the invasion of exotic species, temporary impacts to the habitat as a result of restoration implementation are unavoidable. The resulting restored habitat, however, would provide superior ecological benefits. Permanent Impacts to Jurisdictional Waters & Wetlands. As a result of the water quality improvement and infrastructure components, the project would permanently impact Waters of the United States/State which are characterized as southern riparian forest habitat. Impacts to Waters of the Waters of the United States/State would result from the extension of the culvert into Big Canyon, installation of the stilling basin and rip -rap energy dissipater, the maintenance road and turnaround, and construction of the bioretention cell. Table 3-7, Permanent Impacts to Jurisdictional Areas, defines impact acreages per the regulating resource area. Note, CDFW riparian includes Corps/RWQCB acreage, and CCC wetlands include CDFW and Corps/RWQCB jurisdiction. Thus, maximum permanent jurisdictional impacts do not exceed 0.57 acre. TABLE 3-7 PERMANENT IMPACTS TO JURISDICTIONAL AREAS Habitat Types Jurisdictional Area Impacts (acres) Corps/RWQCB Wetlands Corps/RWQCB Non -Wetlands 0.24 CDFW Riparian 0.44 CCC Wetland 0.57 SOURCE: ESA, 2015 Temporary Impacts to Jurisdictional Waters & Wetlands. Temporary impacts to jurisdictional areas would occur from implementation of the riparian habitat restoration component of the project. This includes the floodplain restoration grading, construction of the vegetated soil lifts and willow brush matts, and exotic removal activities. Because of the extensive invasive species presence in both the understory and overstory vegetation, the majority of impacts are considered beneficial, in that they would result in improved riparian health. Note that if additional exotic species are found in areas during implementation, temporary disturbances areas may be slightly higher. Combined Permanent and Temporary Impacts to Jurisdictional Waters & Wetlands. The permanent and temporary impacts to jurisdictional waters and wetlands identified above are considered significant. Mitigation Measures 13I0-3: Jurisdictional Wetlands. As stated previously, the project has been designed to avoid and minimize impacts to jurisdictional resources and high-quality habitat to the extent practicable. To mitigate for unavoidable permanent impacts to Waters of the United States/State, both habitat creation and enhancement activities would be conducted onsite, as summarized in Table 3-8. Big Canyon Habitat Restoration and Water Quality Improvement Project 3-23 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist TABLE 3-8 MITIGATION FOR PERMANENT IMPACTS TO JURISDICTIONAL AREAS Permanent Impacts Habitat Types (acres) Mitigation for Jurisdictional Impacts Corps/RWQCB Non-Wetlands/CDFW 0.24 0.25 acre of riparian forest habitat Riparian/CCC Wetland creation (1:1 mitigation ratio)1 CDFW Riparian only 0.19 0.64 acre of habitat enhancement CCC Wetland only 0.33 (extensive invasive species removal) Fullfills Corps "no net loss" requirement. SOURCE: ESA, 2015 To offset for permanent losses to 0.24 acre of non -wetland waters of the United States (Corps/RWQCB), 0.44 acre of CDFW and 0.57 acre of CCC jurisdictional wetlands, the creation of 0.25 acre of new habitat is proposed directly to the southwest of the proposed bioretention cell. This would satisfy the federal mandate for no net loss of wetlands by the Corps. The deficit acreage (0.19 acre for CDFW and 0.33 acre for CCC) would be satisfied through the removal of non-native vegetation in adjacent riparian and seed source areas (i.e., riparian habitat enhancement). This would include removal of the Brazilian peppertrees both east of Jamboree Road and on the north slopes of the canyon west of Jamboree Road that are the primary source of invasive seeds for Big Canyon. In addition, understory invasives not mapped by Dudek, including pampas grass, periwinkle, and English ivy, are prevalent throughout the project area. These species would be removed as part of the enhancement activities. Approximately 0.64 acre of invasive removal of the 1.07 acres available would be considered mitigation for unavoidable permanent impacts. Enhancement activities are distinguished from the restoration activities proposed (not mitigation) in that restoration would require grading and extensive soil remediation to achieve full habitat functioning, and enhancement areas would not. Jurisdictional areas temporarily impacted as a result of construction of the water quality or infrastructure -related components of the project would be restored to native habitat at a 1:1 ratio. A full Habitat Restoration Plan describing the Big Canyon restoration as well as habitat mitigation activities would be submitted for review and approval as part of the environmental permitting process. Significance after Mitigation With implementation of Mitigation Measure BI0-3, impacts to jurisdictional wetlands would be reduced to less than significant through the restoration of native habitat at a 1:1 ratio.

Environmental Checklist d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of wildlife nursery sites? Less than Significant with Mitigation Incorporated. The project could temporarily disrupt wildlife movement during construction of the infrastructure and water quality components as well as invasive species removal, floodplain grading, and planting in the riparian habitat restoration area. This temporary disruption to wildlife movement and potential impact on native wildlife nursery sites would be considered significant. Mitigation Measure Implementation of Mitigation Measure BI0-2 is required. Significance after Mitigation With implementation of Mitigation Measure BIO -2, onsite habitat would be restored and would be a higher functioning habitat that can provide cover and forage for migrating wildlife. The potential impacts to wildlife movement and nursery sites would be reduced to less than significant. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? No Impact. The project would not conflict with the protection of biological resources under the City of Newport Beach Municipal Code, or the City's proposed LCP Coastal Land Use Plan (2015 revised submittal). The proposed project, while not currently included in the Orange County Central -Coastal NCCP/HCP, would be designated to meet Plan standards. The highly degraded riparian channel, floodplain, and native vegetation would be restored to better functioning riparian habitat; restoration of adjacent coastal sage scrub areas would provide higher -quality upland habitat for wildlife and wetland buffer function; and the water quality facilities would greatly improve the hydrology and water quality of the creek. Therefore, the project would not conflict with the provisions of any local policies or ordinances protecting biological resources or any NCCP/HCPs. f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? No Impact. The project would not conflict with the protection of biological resources under the City of Newport Beach Municipal Code, or the City's proposed LCP Coastal Land Use Plan (2015 revised submittal). The proposed project, while not currently included in the Orange County Central -Coastal NCCP/HCP, would be designated to meet Plan standards.

Environmental Checklist 3.5 Cultural Resources Discussion The following evaluation is a summary of the findings provided in the Cultural Resources Study prepared by ESA in January 2016. This report contains confidential information and is not for public distribution. a) Cause a substantial adverse change in the significance of a historical resource as defined in 15064.5? Less than Significant with Mitigation Incorporated. No built resources, archaeological sites, or tribal cultural resources were identified in the project area as a result of the current study, which included archival research, pedestrian survey, a search of the Sacred Lands File at the Native American Heritage Commission, and Native American outreach. That said, numerous prehistoric archaeological sites do occur throughout the area. A records search at the South Central Coast Information Center (SCCIC) shows that 35 archaeological resources have been recorded in a 1 mile radius, and that 5 of these occur with 0.15 mile. While most of these occur on ridgetops and mesas above and outside the project area, Native American representatives and the Sacred Lands File search indicate that the area contains sensitive archaeological resources. Given this, and given the fact that the archaeological survey only addressed resources visible on the surface, and that certain heavily vegetated areas were not accessible for survey, there is a potential, though small, that earthmoving activity could impact buried archaeological resources. This potential impact on unknown archaeological resources would be considered significant. Mitigation Measures CR -1: Archaeological Monitoring. An archaeological monitor (working under the direct supervision of a Secretary of the Interior -qualified archaeologist [USDI 2008]) shall be retained to observe all ground -disturbing activities, including but not limited to brush clearance, vegetation removal, grubbing, grading, and excavation.

An archaeological monitor (working under the direct supervision of a Secretary of the Interior -qualified archaeologist [USDI 2008]) shall be retained to observe all ground -disturbing activities, including but not limited to brush clearance, vegetation removal, grubbing, grading, and excavation. Prior to start of ground -disturbing activities, the archaeologist shall conduct cultural resources sensitivity training for all construction personnel. Construction personnel shall be informed of the types of archaeological Big Canyon Habitat Restoration and Water Quality Improvement Project 3-27 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist resources that may be encountered, and of the proper procedures to be enacted in the event of an inadvertent discovery of archaeological resources or human remains. The City shall ensure that construction personnel are made available for and attend the training and retain documentation demonstrating attendance. Archaeological monitoring shall be conducted by an archaeologist familiar with the types of archaeological resources that could be encountered within the project site. The qualified archaeologist, in coordination with the City, may reduce or discontinue monitoring if it is determined that the possibility of encountering buried archaeological deposits is low based on observations of soil stratigraphy or other factors. The archaeological monitor shall be empowered to halt or redirect ground -disturbing activities away from the vicinity of a discovery until the qualified archaeologist has evaluated the discovery and determined appropriate treatment. The archaeological monitor shall keep daily logs detailing the types of activities and soils observed, and any discoveries. After monitoring has been completed, the qualified archaeologist shall prepare a monitoring report that details the results of monitoring. The report shall be submitted to the City, the Corps, and any Native American groups who request a copy. A copy of the final report shall be filed at the SCCIC. If archaeological resources are encountered during monitoring, and if it is determined that the discovered archaeological resource constitutes a historic property under Section 106 of the NHPA or a historical resource under CEQA, avoidance and preservation in place is the preferred manner of treatment. Preservation in place maintains the important relationship between artifacts and their archaeological context and also serves to avoid conflict with traditional and religious values of groups who may ascribe meaning to the resource. Preservation in place may be accomplished by, but is not limited to, avoidance, incorporating the resource into open space, capping, or deeding the site into a permanent conservation easement. In the event that preservation in place is demonstrated to be infeasible and data recovery through excavation is the only feasible mitigation available, a Cultural Resources Treatment Plan would be prepared and implemented by a qualified archaeologist in consultation with the Corps and the City. The plan will provide for the adequate recovery of the scientifically consequential information contained in the archaeological resource. The Corps and the City shall be required to consult with appropriate Native American representatives in determining treatment for prehistoric or Native American resources to ensure cultural values ascribed to the resource, beyond that which is scientifically important, are considered. CR -2: Native American Monitoring. The City shall retain a Native American monitor to observe all ground -disturbing activities, including but not limited to brush clearance, vegetation removal, grubbing, grading, and excavation. The Native American monitor shall be selected from amongst the Native American groups identified by the NAHC as having affiliation with the project area. The Native American representative shall be allowed to participate in the cultural resources sensitivity training, discusses in Mitigation Measure CR -1, and all authorities ascribed to the archaeological monitor, including the authority to stop work in the event of the discovery of cultural resources, shall also apply to the Native American monitor. In the event that Big Canyon Habitat Restoration and Water Quality Improvement Project 3-28 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist archaeological materials are encountered, the Native American monitor shall participate in any discussions involving treatment and subsequent mitigation. Significance after Mitigation With the implementation of Mitigation Measures CR -1 and CR -2, monitoring activities, as well as subsequent data recovery, if necessary, would reduce potential impacts on historical resources to less than significant. b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to 15064.5? Less than Significant with Mitigation Incorporated. As mentioned above, no archaeological resources were identified within the project area. That said, there is the potential to encounter buried resources during construction. This potential to encounter buried archaeological resources would be considered a significant impact. Mitigation Measures Implementation of Mitigation Measures CR -1 and CR -2 is required. Significance after Mitigation The implementation of Mitigation Measures CR -1 and CR -2 would ensure that the project would have a less than significant impact on unique archaeological resources. C) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Less than Significant with Mitigation Incorporated. The results of the paleontological records check at the Natural History Museum of Los Angeles County indicate that the project area is sensitive for paleontological resources. The Monterey Formation underlies younger Quaternary alluvium within the central portion of Big Canyon, and there are exposures of Monterey Formation in the Big Canyon walls. While grading operations will not involve substantial excavation extending into the underlying Monterey Formation within the canyon, or excavations in the exposures of Monterey Formation in the Big Canyon walls, there is a good chance of uncovering significant vertebrate fossil remains. Paleontological resources are considered part of the environment and a project that may directly or indirectly destroy a unique paleontological resource is a project that may have a significant effect on the environment. Therefore, the construction activities associated with the proposed project would result in potential significant impacts on paleontological resources. Mitigation Measures CR -3: Paleontological Monitoring. A qualified paleontologist meeting the Society for Vertebrate Paleontology (SVP) guidelines for professional paleontologist (SVP, 2010) shall be retained to oversee all mitigation measures related to paleontological resources. That said, both the paleontological and archaeological monitoring could be carried out by the same person, Big Canyon Habitat Restoration and Water Quality Improvement Project 3-29 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist presuming the monitor is qualified in both disciplines. During ground disturbing activity, the qualified paleontologist or paleontological monitor shall conduct spot-checks of exposed sediments. The purpose would be to determine whether the project would impact the paleontologically sensitive Monterey Formation. The qualified paleontologist may institute paleontological monitoring if, based on observations of subsurface stratigraphy or other factors, he or she determines that the possibility of encountering fossiliferous deposits is high. Paleontological monitoring would be conducted by a paleontological monitor working under the supervision of the qualified paleontologist. In the event that monitoring is required, the monitor shall have the authority to temporarily halt or divert work away from exposed fossils in order to recover the fossil specimens and shall complete daily monitoring logs outlining the day's activities. The qualified paleontologist shall prepare a final monitoring report to be submitted to the City and filed with the local repository, along with any fossils recovered during construction. The qualified paleontologist shall also contribute to any construction worker cultural resources sensitivity training (see Mitigation Measure CR -1) either in person or via a training module provided to the qualified archaeologist. The training shall include information of the types of paleontological resources that may be encountered, and the proper procedures to be enacted in the event of an inadvertent discovery of paleontological resources. In the event of unanticipated discovery of paleontological resources, the City shall cease ground - disturbing activities within 100 feet of the find until it can be assessed by the qualified paleontologist. The qualified paleontologist shall assess the find, implement recovery measures if necessary, and determine if paleontological monitoring is warranted once work resumes. Significance after Mitigation The implementation of Mitigation Measure CR -3 would ensure that the project would have a less than significant impact on paleontological resources or unique geologic features. d) Disturb any human remains, including those interred outside formal cemeteries? No Impact. No human remains were identified in the project area as a result of the archival research or survey, and it is anticipated that the project would have no impact on human remains. That said, the area was known to have been used by prehistoric Native Americans. In the unlikely event that human remains are uncovered during ground disturbing activities, appropriate state law would apply. Specifically, California Health and Safety Code Section 7050.5 requires that in the event human remains are discovered, the County Coroner be contacted to determine the nature of the remains. In the event the remains are determined to be Native American in origin, the Coroner is required to contact the NAHC within 24 hours to relinquish jurisdiction. Further, California PRC Section 5097.98, as amended by Assembly Bill 2641, provides procedures in the event human remains of Native American origin are discovered during project implementation. PRC Section 5097.98 requires that no further disturbances occur in the immediate vicinity of the discovery, that the discovery is adequately protected according to generally accepted cultural and archaeological standards, and that further activities take into Big Canyon Habitat Restoration and Water Quality Improvement Project 3-30 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist account the possibility of multiple burials. PRC Section 5097.98 further requires the NAHC, upon notification by a County Coroner, designate and notify a Most Likely Descendant (MLD) regarding the discovery of Native American human remains. Once the MLD has been granted access to the site by the landowner and inspected the discovery, the MLD then has 48 hours to provide recommendations to the landowner for the treatment of the human remains and any associated grave goods. In the event that no descendant is identified, or the descendant fails to make a recommendation for disposition, or if the land owner rejects the recommendation of the descendant, the landowner may, with appropriate dignity, reinter the remains and burial items on the property in a location that would not be subject to further disturbance.

Discussion a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? (Refer to Division of Mines and Geology Special Publication 42.) No Impact. Based on a review of the City of Newport Beach General Plan, Safety Element, the City is located in the northern part of the Peninsular Ranges Province which is an area that is exposed to risks from multiple earthquake fault zones. The nearest earthquake that contains an Alquist-Priolo Earthquake Fault Zone is the Newport - Inglewood fault zone. This fault is located offshore from the City of Newport Beach. Based on a review of the Special Studies Zones map prepared by the California Division of Mines and Geology, there are no Alquist-Priolo Earthquake Fault Zones on the project Big Canyon Habitat Restoration and Water Quality Improvement Project 3-32 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist site. Therefore, the proposed project would not be exposed to a rupture of a known earthquake fault. ii) Strong seismic ground shaking? Less than Significant Impact. The largest earthquake magnitude within a 100 -mile radius of the project site between 1800 and 2006 was 7.6 magnitude GSI 2006). The project site is subject to varying ground shaking intensities similar to other areas within the region. The City requires that all construction meet the latest standards of the California Building Code (CBC) which considers proximity to potential seismic sources and the maximum anticipated ground shaking possible. The construction of the proposed facilities on the project site would be in accordance with applicable City ordinances and policies and consistent with the most recent version of the CBC which requires structural design that can accommodate ground accelerations expected from known active faults. Compliance with the City's safety design standards as well as the CBC would reduce potential impacts associated with seismic ground shaking to less than significant. iii) Seismic -related ground failure, including liquefaction? Less than Significant Impact. Liquefaction is a secondary earthquake -induced hazard that occurs when water -saturated soils lose their strength and liquefy during intense and prolonged ground shaking. Based on a review of the Newport Beach General Plan, the project site includes areas that are susceptible to liquefaction. Adherence to the CBC and the City's Municipal Code requirements would implement proven geotechnical design measures that would minimize the potential for liquefaction, and potential impacts would be less than significant. iv) Landslides? Less than Significant Impact. Based on a review of the Newport Beach General Plan, the project site contains a few areas that could be susceptible to landslides. Project implementation would be required to adhere to the CBC and the City's Municipal Code to ensure the potential for landslides is reduce to less than significant. b) Result in substantial soil erosion or the loss of topsoil? Less than Significant Impact. During project construction, excavation and grading would be required. These activities would expose soil to erosive elements such as wind and rain. However, project construction would be required to comply with existing regulatory requirements that address soil erosion such as the National Pollutant Discharge Elimination System (NPDES) program. Any development site, such as the project site, that would disturb one or more acres would be required to develop and implement a Storm Water Pollution Prevention Plan (SWPPP) which includes the use of erosion control Best Management Practices to protect surface water and groundwater from the adverse effects of construction activities. Big Canyon Habitat Restoration and Water Quality Improvement Project 3-33 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist The erosion control best management practices (BMPs) such as scheduling, preservation of existing vegetation, hydroseeding, sandbags, fiber rolls, and silt fences would prevent the exposure of soil to wind and water and reduce the threat of erosion during construction to less than significant. Once constructed, the potential for erosion or loss of topsoil is substantially reduced. The project would include creek restoration activities that would include floodplain restoration, streambank stabilization and habitat restoration. Floodplain restoration and streambank stabilization activities would result in flood flow attenuation, stabilization of the north bank of the main channel, and creation of an active sinous riparian floodplain. The north creek bank at the inlet would be stabilized using natural bioengineering techniques. Riparian habitat would be restored directly downstream of the floodplain restoration area through the removal of invasive trees, soil remediation to reduce plant -limiting sodium levels, and replacement with native riparian species. The proposed project would reduce the potential for soil erosion or loss of topsoil to less than significant. C) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse? Less than Significant Impact. As described above, the development of the proposed structures would be required to adhere to the CBC and City requirements. These requirements would ensure that appropriate engineering techniques are implemented to reduce any potential for landslides, lateral spreading, subsidence, liquefaction or collapse to less than significant. d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial risks to life or property? Less than Significant Impact. Although the west side of Big Canyon contains previously dredged materials from Upper Newport Bay that could contain expansive soils, it is unknown if the project site contains expansive soil. As stated above, the proposed structures would be required to comply with the CBC and the City requirements for stable soils. Compliance with these requirements would reduce the potential impacts to less than significant. e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? No Impact. The proposed project does not include septic tanks or alternative waste disposal systems. As a result, there is no potential for soil failure associated with the installation of septic tanks or alternative waste disposal systems.

Environmental Checklist 3.7 Greenhouse Gas Emissions Issues (and Supporting Information Sources): 7. GREENHOUSE GAS EMISSIONS — Would the project: a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? Discussion Gases that trap heat in the atmosphere are referred to as greenhouse gases (GHGs) because they capture heat radiated from the sun as it is reflected back into the atmosphere, much like a greenhouse does. The accumulation of GHGs has been implicated as a driving force for global climate change. Definitions of climate change vary between and across regulatory authorities and the scientific community, but in general can be described as the changing of the earth's climate caused by natural fluctuations and anthropogenic activities, which alter the composition of the global atmosphere. Prominent GHGs contributing to the greenhouse effect are carbon dioxide (CO2), methane (CH4), nitrous oxide (N20), hydrofluorocarbons (HFCs), chlorofluorocarbons (CFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). Carbon dioxide is the "reference gas" for climate change, meaning that emissions of GHGs are typically reported in "carbon dioxide -equivalent" (CO2e) measures. There is international scientific consensus that human -caused increases in GHGs have and will continue to contribute to global warming, although there is uncertainty concerning the magnitude and rate of the warming. Potential global warming impacts in California may include, but are not limited to, loss in snow pack, sea level rise, more extreme heat days per year, more high ozone days, more large forest fires, and more drought years. Secondary effects are likely to include global rise in sea level, impacts to agriculture, changes in disease vectors, and changes in habitat and biodiversity. In 2005, in recognition of California's vulnerability to the effects of climate change, Governor Schwarzenegger established Executive Order S-3-05, which sets forth a series of target dates by which statewide emissions of GHG would be progressively reduced, as follows: • By 2010, reduce GHG emissions to 2000 levels; • By 2020, reduce GHG emissions to 1990 levels; and • By 2050, reduce GHG emissions to 80 percent below 1990 levels. In 2006, California passed the California Global Warming Solutions Act of 2006 (Assembly Bill No. 32; California Health and Safety Code Division 25.5, Sections 38500, et seq., or AB 32), which requires CARB to design and implement emission limits, regulations, and other measures, Big Canyon Habitat Restoration and Water Quality Improvement Project 3-36 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 Less Than Significant Potentially with Less Than Significant Mitigation Significant Impact Incorporation Impact No Impact ❑ ❑ ® ❑ ❑ ❑ ❑ Gases that trap heat in the atmosphere are referred to as greenhouse gases (GHGs) because they capture heat radiated from the sun as it is reflected back into the atmosphere, much like a greenhouse does.

Environmental Checklist such that feasible and cost-effective statewide GHG emissions are reduced to 1990 levels by 2020. On March 18, 2010, the California Office of Planning and Research (OPR) submitted amendments to the CEQA Guidelines for GHG emissions, as required by Public Resources Code section 21083.05. These CEQA Guideline amendments provide guidance to public agencies regarding the analysis and mitigation of the effects of GHG emissions in draft CEQA documents. The amendments are relatively modest changes to various portions of the existing CEQA Guidelines. a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? Less than Significant Impact. The proposed project would primarily contribute to global climate change as a result of emissions of GHGs, primarily CO2, emitted during construction activities associated with the installation of a surface water treatment system, including a pump station and culvert improvements. Once construction activities have been completed, operation of the proposed project would only generate minimal GHG emissions sources from vehicle emissions associated with worker trips to and from the project area for routine maintenance of the surface water treatment structure. However, because these trips would only occur once a month, these GHG emissions would be negligible. GHG impacts are considered to be exclusively cumulative impacts (CAPCOA, 2008); there are no non -cumulative GHG emission impacts from a climate change perspective. Thus, the purpose of this GHG analysis is to determine whether the contribution of GHG emissions by the proposed project would be cumulatively considerable. The City of Newport Beach has not adopted any significance criteria or guidelines for GHG analysis. SCAQMD has issued proposed standards and guidelines, proposing a 10,000 metric ton per year (MT/year) CO2e threshold for industrial projects for which it is the lead agency. Additionally, SCAQMD has proposed, a 3,000 MT/year CO2e threshold for residential and commercial developments (SCAQMD, 2008). For the purpose of this analysis, the project's total annual GHG emissions resulting from construction activities have been quantified and evaluated against the 3,000 MT/year CO2e screening criteria. As was conducted for the proposed project's air quality analysis in Question 3 (Air Quality), the project's construction -related GHG emissions were estimated for equipment exhaust, truck trips, and worker commute trips using CalEEMod. The project's estimated annual GHG emissions during construction are shown in Table 3-9. With respect to construction GHG emissions, SCAQMD recommends that the total emissions for a project be amortized over a 30 -year period and added to its operational emission estimates (SCAQMD, 2008). To determine the total construction emissions that would be generated from the project's surface water treatment system, the annual GHG emissions under a worst-case construction scenario was taken to conservatively represent the total emissions that would be generated from construction of the proposed project. Total construction -related GHG emissions was calculated to be 103.97 CO2e MT/yr. Amortized over 30 years, the proposed project Big Canyon Habitat Restoration and Water Quality Improvement Project 3-37 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist construction -related GHG emissions would be 3.47 COZe MT/yr. With respect to operational emissions, the only GHG emissions generated by the proposed project would be periodic maintenance on-site. This maintenance would include maintenance of the water dosing station, monitoring the bioretention cell for any debris buildup and maintenance of any invasive or dead vegetation removal. The periodic maintenance would not be expected to result in higher GHG emissions than produced by construction activities. Therefore, a conservative estimate of the operational GHG emissions was chosen as 20% of the annual construction GHG emissions. TABLE 3-9 ESTIMATED PROJECT CONSTRUCTION GHG EMISSIONS Emission Source Proposed Project EmissionsCOze (MT/yr) Construction Annual Project Construction (Amortized over 30 yrs)' 3.47 Operation 20.79 Total Annual Emissions 24.26 CAPCOA Screening Threshold 3000 Significant Impact? No NOTES: COze= carbon dioxide equivalent; MT/yr = metric tons per year; see Appendix B for CalEEMod model outputs. a The total project construction GHG emissions were derived by summing the annual construction emissions (MT/yr) for all nine phases. Total project construction GHG emissions = 103.97 CO2e MT/yr. Amortized over 30 years, annual project construction GHG emissions = 3.47 COze MT/yr. As shown in Table 3-9, the proposed project's total annual GHG emissions resulting from construction activities and project operation would be approximately 24.26 MT CO2e per year. Thus, the project's total annual GHG emissions would not exceed the 3,000 MT of COze per year screening threshold recommended by SCAQMD. Therefore, the proposed project would not result in the generation of substantial levels of GHG emissions and would not result in emissions that would adversely affect the statewide attainment of GHG emission reduction goals of AB 32. This impact would be less than significant. b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? No Impact. The proposed project would generate temporary construction -related GHG emissions and minimal GHG emissions during operations. Because the proposed project only involves the installation of surface water treatment infrastructure, culvert improvements and restoration activities, implementation of the project would not result in, or induce, growth in the project area that has not been accounted for by the City of Newport Beach. Consequently, no growth -inducing development or land use that would generate GHG emissions would occur under the project. The proposed project would not conflict with any adopted plan's goals of reducing GHG emissions. Big Canyon Habitat Restoration and Water Quality Improvement Project 3-38 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist Overall, implementation of the proposed project would not conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of GHGs. Therefore, this impact would be less than significant.

Less than Significant Impact. Construction activities associated with the proposed project would involve site clearing, excavation, grading, and other ground -disturbing activities. Construction activities would be required for the installation of the project facilities, including the culvert extension, the bioretention cell liner and piping, and the bioengineering structure construction. Construction activities would occur for approximately five months within the project site. The proposed construction activities would require the use of equipment, such as loaders, excavators, trucks, and other powered equipment, and would therefore use fuels (gasoline or diesel) and lubricants (oils and greases). All construction equipment would be housed within the staging area of the project site. The construction equipment on site may require minor Big Canyon Habitat Restoration and Water Quality Improvement Project 3-40 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist maintenance during construction activities, which may result in the disposal of hazardous byproducts from the equipment. Operation of the proposed facilities would involve the routine and major maintenance of the wetland basin. This would include the removal of trash, debris, and dying vegetation that interfere with facility maintenance. Maintenance activities would also include removal of any visual contamination from floatables, such as oil and grease, and repairs to any flow control structures as needed to maintain full functionality. Operational activities would involve limited amounts of hazardous materials used in and transported to the project site. The use of hazardous materials and substances during construction and operation activities would be subject to federal, state, and local health and safety requirements for handling, storage, and disposal. Therefore, hazardous material impacts related to construction activities would be less than significant. b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? Less than Significant Impact. As discussed above in discussion 3.8(a), limited quantities of hazardous materials such as gasoline, diesel, oils, and lubricants may be required to operate the construction equipment. Construction activities would be short-term, and the use of these materials would cease once construction is complete. The hazardous substances used during construction would be required to comply with existing federal, state and local regulations regarding the use and disposal of these materials. In the event of an accidental release during construction, containment and clean up would be in accordance with existing applicable regulatory requirements. Project operation would involve minimal transport and use of hazardous materials onsite. The use of hazardous materials and substances during construction and operation activities would be subject to federal, state, and local health and safety requirements for handling, storage, and disposal. Potential impacts to the public or the environment related to reasonably foreseeable accident conditions involving hazardous materials would be less than significant. C) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? Less than Significant Impact. The nearest existing school to the project site is Our Lady Queen of Angels High School located approximately 0. 16 miles north of the project site. In addition, Corona Del Mar High School is located approximately 0.25 miles north of the project site. Therefore, there are two schools within one-quarter mile of the proposed project area. Construction within the project site would include the use of loaders, dozers, haul trucks, compactors, and water trucks. Hazardous materials, such as oil, solvents, and gasoline, needed for the maintenance of the construction equipment would be used only in small quantities on the project site, and the use of hazardous substances would be compliant with City code regulations and Best Management Practices. Hazardous materials would not be transported on a routine basis. Construction activities are to last approximately five months; therefore, construction -related hazardous materials would be only temporarily present on site and subsequently removed after Big Canyon Habitat Restoration and Water Quality Improvement Project 3-41 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist construction is completed. Operation of the proposed project would not introduce any hazardous emissions or materials into the project site. Therefore, the proposed project would result in less than significant hazardous material -related impacts to schools within a quarter -mile of the project. d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? No Impact. Pursuant to Government Code 65962.5, environmental regulatory database lists were reviewed to identify and locate properties with known hazardous substance contamination within the proposed project area (California Government Code, Section 65960 et seq.) (see Appendix D). A review of the Department of Toxic Substances Control's (DTSC) Hazardous Waste and Substances List — Site Cleanup (Cortese List) indicates that identified hazardous material sites are not located within the project area (DTSC, 2007). There was a formerly leaking underground storage tank across the street at Big Canyon Country Club, but the case has closed as of May 15, 2001 (EDR, 2016). A review of the DTSC EnviroStor and the State Water Resources Control Board GeoTracker online databases did not indicate any open cleanup sites or hazardous waste facilities within the vicinity of the project area. Therefore, since the project is not located on a list associated with hazardous materials, no impacts would occur. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? No Impact. The nearest public airport to the project site is John Wayne Airport (JWA), approximately 2.5 miles north of the site. The John Wayne Airport Safety Compatibility Zones are defined in the Airport Environs Land Use Plan for JWA (ALUC, 2013). The proposed project is not located within any Safety Compatibility Zones for JWA. No impacts to safety hazards for people residing or working in the project area would occur. f) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? No Impact. The proposed project is not located within the vicinity of a private airstrip. The nearest private airstrip to the project site is the L.A. Times Costa Mesa Heliport approximately 5 miles northwest of the project site (www.tollfreeairline.com). No airstrip related hazard impacts would occur. g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? No Impact. The Newport Beach Fire Department prepared an Emergency Operations Plan (EOP) that was adopted by the City of Newport Beach in September 2011. The purpose of the EOP is to provide guidance for the City's response to extraordinary emergency situations associated with natural disasters, technological incidents, and national security emergencies in or affecting the Big Canyon Habitat Restoration and Water Quality Improvement Project 342 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist City of Newport Beach. The EOP also shows the City's emergency evacuation routes in the event of a tsunami. The project site is located along Jamboree Road, a designated emergency evacuation route. The proposed project would be constructed completely within the proposed project boundary. Construction equipment as well as haul trucks would access the site from Jamboree Road, and then travel west at the intersection of San Joaquin Road and Jamboree Road onto San Joaquin Road. Construction vehicles would travel to Back Bay Drive, and then travel north on Back Bay Drive to the Big Canyon Trail maintenance road entrance. Construction vehicles would follow the maintenance road east to the construction staging area. There would be no road closures or alterations to Jamboree Road during construction and all construction equipment would be stored in active grading areas and/or the proposed staging areas within the project area. Once constructed, the proposed project does not include any uses or design features that would result in interference with any adopted emergency response plan or emergency evacuation plan. The design of the proposed project would provide adequate emergency access consistent with City requirements, including public access trails within the project site. Therefore, the proposed project would not result in impacts to emergency access during construction and/or operation. The proposed project would not impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan and, thus, the project would result in no impact. h) Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? No Impact. The project site is not located in an area classified as a "Wildland Area That May Contain Substantial Forest Fire Risks and Hazards" or a "Very High Fire Hazard Severity Zone" by the California Department of Forestry and Fire Protection (CAL FIRE 2011). Therefore, the risk for wildland fire hazards is low, and project implementation would result in no impact to people or structures to a significant fire risk.

Discussion a) Violate any water quality standards or waste discharge requirements? No Impact. The proposed project would not violate any water quality standards or waste discharge requirements because the project includes treatment facilities that would improve surface water quality in the project area. Big Canyon Habitat Restoration and Water Quality Improvement Project 3-44 ESA / Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre- existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? Less than Significant Impact. Groundwater would be not required for construction or operation of the proposed project. Surface seeps along the creek bank immediately upstream and downstream of the culvert under Jamboree Road would be collected and diverted to the sanitary sewer due to the high selenium concentrations measured in these seeps. The collection and diversion of the significant source of selenium to the creek would measurably reduce downstream selenium concentrations and improve water quality through the creek segment that runs through the Big Canyon Preserve. This would allow for successful restoration efforts associated with the proposed project The estimated seepage flows are anticipated to be less than 10% of the total current dry weather flows in Big Canyon Creek. Therefore, approximately 90% of the current dry weather flows would be returned to the creek. Diverting the high selenium seepage flows would substantially reduce in -stream selenium concentrations in the downstream creek flowing through the restoration area. Because the project would not require the use of groundwater and the project would divert the current high selenium from seepage flows, the project would result in less than significant impacts on groundwater supplies. C) Substantially alter the existing drainage pattern of area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site? Less than Significant Impact. The project includes creek restoration activities that would include floodplain restoration, streambank stabilization and habitat restoration. Floodplain restoration and streambank stabilization activities would result in flood flow attenuation, stabilization of the north bank of the main channel, and creation of an active sinous riparian floodplain. The north creek bank at the inlet would be stabilized using natural bioengineering techniques. Riparian habitat would be restored directly downstream of the floodplain restoration area through the removal of invasive trees, soil remediation to reduce plant -limiting sodium levels, and replacement with native riparian species. The proposed project would reduce the potential for erosion and siltation to less than significant. d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on - or off-site? Less than Significant Impact. The additional impervious surfaces or other similar features are not substantial to cause any noticeable increase in surface runoff. Furthermore, the project includes the construction of a water quality treatment bioretention cell that would treat wet - weather flows from Jamboree Road. In order to treating the pollutants, stormwater flows from Jamboree that currently discharge directly into the riparian creek corridor, would be directed to Big Canyon Habitat Restoration and Water Quality Improvement Project 3-455 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist the bioretention cell that would retain and filter these flows. Following treatment of the stormwater, the flow would be discharged through an outlet structure that would control the rate of discharge. Therefore peak storm flows that can impact downstream sections of the creek would be attenuated. The proposed project would therefore reduce peak flows that may impact the sensitive habitat of the site, and potential flooding impacts associated with the project would be less than significant. e) Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? No Impact. Surface flow rates that currently discharge to the site from Jamboree Road would be measurably reduced by the bioretention cell. The project includes a new permanent access that would include adequately design stormwater drainage features to accommodate the proposed flows and not impact downstream areas. In addition, the project would not add additional sources of polluted runoff, but would improve downstream surface water quality through the implementation of the proposed surface water quality improvements. The proposed project would result in no impacts to the capacity of the existing stormwater drainage system and no impacts to downstream surface water quality. f) Otherwise substantially degrade water quality? No Impact. The Project would result in positive water quality improvement for both stormwater and dry weather surface flows. Storm Flows — The purpose of the stormwater treatment system is to reduce transportation - related constituent concentrations currently discharged to Big Canyon Creek during storm events and to attenuate stormwater peak -flow discharge rates from the contributing Jamboree Road drainage area. The transportation -related pollutants are currently conveyed to the receiving waters in Big Canyon Creek from a variety of sources, including vehicles, road maintenance, maintenance facility runoff, and landscaping maintenance. Vehicles are known to produce a variety of pollutants that can have a negative impact on water quality in the receiving waters to which they drain. Metals such as copper and zinc can build up on road surfaces through brake and tire wear; other metals such as cadmium, chromium and sometimes lead can be deposited on road surfaces from paint on vehicles and streets. Metals often bind to sediments, trash, and debris on road surfaces; these can be carried into waterways during storm events. In addition to pollutants associated with vehicles, landscaped areas associated with or adjacent to streets (e.g., median, parkway, and residential landscaping) can be sources of pollutants such as pesticides, nutrients (particularly nitrate and phosphorus), and fecal -indicator bacteria (all of which are known to be associated with urban landscaping, which is found throughout the 11.1 -acre Jamboree Road drainage area). These pollutants can be transported to receiving waters during storm events. Finally, in addition to direct deposition to the road surface, street surfaces and adjacent walkways and landscaped areas can be impacted from vehicle emissions through atmospheric deposition of pollutants such as the dissolved fraction of metals and organics (e.g., polynuclear aromatic hydrocarbons (PAHs). Big Canyon Habitat Restoration and Water Quality Improvement Project 3-46 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist According to national and regional best management practices (BMPs) manuals (e.g., the California Stormwater Quality Association BMP handbook), the technology proposed in the stormwater treatment system has been shown to be effective in treating a variety of pollutants associated with transportation runoff, including trash, sediment (and attached pollutants), nutrients and organics such as PAHs and pesticides, and fecal -indicator bacteria. The stormwater treatment system would consist of a primary stormwater treatment structure and a bioretention cell, as described below. Dry Weather Flows The purpose of the dry weather flow diversion is to limit the contact between dry weather flows with low selenium concentrations with groundwater seepage flows that contain much higher selenium concentrations. Surface seeps would be passively collected and diverted to the sanitary sewer. The lower concentration dry weather flows would be diverted around the higher selenium seeps and back into the creek channel. Selenium reductions of 70- 90% are anticipated in downstream flows. These reductions would allow for successful and sustainable restoration of the creek as part of the proposed project and in potential future downstream restoration efforts. Overview With the implementation of the proposed project, surface and groundwater quality would not be impacted. g) Place housing within a 100 -year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? No Impact. All residential properties are on the high banks above the 100 -year floodplain. These banks would not be impacted by the proposed project. h) Place within a 100 -year flood hazard area structures which would impede or redirect flood flows? Less than Significant Impact. One -Hundred year flows from Big Canyon Creek would be directed through the restored creek section and the downstream stream channels. This proposed project would improve surface water hydrology by reducing peak flows from Jamboree Road that would be directed through the proposed bioretention cell. The currently incised creek channel downstream of the culvert would be restored to include a wider floodplain and the northern bank stabilized using bio -engineering techniques. The extended culvert element to accommodate the new access road includes the implementation of concrete stilling basin and grade control structure to dissipate storm flows and reduce the potential for downstream erosion. The planned restoration would include removal of invasive plants and re -vegetation with native plants that would also improve overall hydrology. The implementation of the proposed facilities on the project site would result in less than significant impacts associated with a 100 -year flood hazard area.

Environmental Checklist i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? No Impact. No risk associated with property loss or life threatening conditions would result from the proposed project as no significant changes in site hydrology would occur as a result of the project. Hydraulic analysis of the proposed flood control conveyance show that velocities in the conveyance would be below erosive levels due to the 2% longitudinal slope and heavily vegetated side slopes. The proposed project would not increase the risk of people or structures to loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam. The watershed is heavily urbanized and the Upper Newport Bay is protected against ocean waves. Therefore, the proposed project would result in no impacts related to flooding. j) Expose people or structures to a significant risk of loss, injury or death involving inundation by seiche, tsunami, or mudflow? No Impact. No risk associated with property loss or life threatening conditions would result from the proposed project as no significant changes in site hydrology would occur as a result of the project. Hydraulic analysis of the proposed flood control conveyance show that velocities in the conveyance would be below erosive levels due to the 2% longitudinal slope and heavily vegetated side slopes. The proposed project would not increase the risk of the project area or surrounding land to be inundated as a result of seiche, tsunami, or mudflow. The watershed is heavily urbanized and the Upper Newport Bay is protected against ocean waves. Therefore, the proposed project would result in no impacts related to seiche, tsunami or mudflow.

Discussion 3. Environmental Checklist a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the State? No Impact. Based on the guidelines adopted by the California Geological Survey (CGS), areas known as Mineral Resource Zones (MRZ) are classified according to the presence or absence of significant mineral resource deposits.

Discussion 3. Environmental Checklist ❑ ❑ ❑ Noise is generally defined as unwanted sound. Sound, traveling in the form of waves from a source, exerts a sound pressure level (referred to as sound level) that is measured in decibels (dB), which is the standard unit of sound amplitude measurement. The dB scale is a logarithmic scale that describes the physical intensity of the pressure vibrations that make up any sound, with 0 dB corresponding roughly to the threshold of human hearing and 120 to 140 dB corresponding to the threshold of pain. Pressure waves traveling through air exert a force registered by the human ear as sound. Sound pressure fluctuations can be measured in units of hertz (Hz), which correspond to the frequency of a particular sound. Typically, sound does not consist of a single frequency, but rather a broad band of frequencies varying in levels of magnitude. When all the audible frequencies of a sound are measured, a sound spectrum is plotted consisting of a range of frequency spanning 20 to 20,000 Hz. The sound pressure level, therefore, constitutes the additive force exerted by a sound corresponding to the sound frequency/sound power level spectrum. The typical human ear is not equally sensitive to all frequencies of the audible sound spectrum. As a consequence, when assessing potential noise impacts, sound is measured using an electronic filter that deemphasizes the frequencies below 1,000 Hz and above 5,000 Hz in a manner corresponding to the human ear's decreased sensitivity to extremely low and extremely high frequencies.

Environmental Checklist in units of A -weighted decibels (dBA). A -weighting follows an international standard methodology of frequency deemphasis and is typically applied to community noise measurements. An individual's noise exposure is a measure of noise over a period of time. While a noise level is a measure of noise at a given instant in time, community noise varies continuously over a period of time with respect to the contributing sound sources of the community noise environment. Community noise is primarily the product of many distant noise sources, which constitute a relatively stable background noise exposure, with the individual contributors unidentifiable. The background noise level changes throughout a typical day, but does so gradually, corresponding with the addition and subtraction of distant noise sources such as traffic. What makes community noise variable throughout a day, besides the slowly changing background noise, is the addition of short -duration, single -event noise sources (e.g., aircraft flyovers, motor vehicles, sirens), which are readily identifiable to the individual. These successive additions of sound to the community noise environment change the community noise level from instant to instant, requiring the measurement of noise exposure over a period of time to legitimately characterize a community noise environment and evaluate cumulative noise impacts. This time -varying characteristic of environmental noise is described using statistical noise descriptors. The most frequently used noise descriptors are summarized below: Leq: The Leq, or equivalent sound level, is the energy -mean dBA during a measured time interval. It is the "equivalent" constant sound level that would have to be produced by a given source to equal the acoustic energy contained in the fluctuating sound level measured. L.,: The maximum, instantaneous noise level experienced during a given period of time. Lmio: The minimum, instantaneous noise level experienced during a given period of time. Ldn: Also termed the DNL, the Ldn is defined as the A -weighted average sound level for a 24- hour day with a 10 -dB penalty added to nighttime sound levels (10:00 p.m. to 7:00 a.m.) to compensate for increased sensitivity to noise during usually quieter evening and nighttime hours. CNEL: CNEL, or Community Noise Equivalent Level, is defined as the A -weighted average sound level for a 24-hour day. It is calculated by adding a 5 -dB penalty to sound levels in the evening (7:00 p.m. to 10:00 p.m.) and a 10 -dB penalty to sound levels at night (10:00 p.m. to 7:00 a.m.) to compensate for increased sensitivity during such time periods when a quiet environment is expected. An important way of predicting a human reaction to a new noise environment is the way it compares to the existing environment to which one has adapted (i.e., comparison to the ambient noise environment). In general, the more a new noise level exceeds the previously existing Big Canyon Habitat Restoration and Water Quality Improvement Project 3-54 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist ambient noise level, the less acceptable the new noise level would be judged by those hearing it. With regard to increases in A -weighted noise level, the following relationships generally occur: • Except in carefully controlled laboratory experiments, a change of 1 dBA cannot be perceived; • Outside of the laboratory, a 3 dBA change in noise levels is considered to be a barely perceivable difference; • A change in noise levels of 5 dBA is considered to be a readily perceivable difference; and • A change in noise levels of 10 dBA is subjectively heard as doubling of the perceived loudness. These relationships occur in part because of the logarithmic nature of sound and the decibel system. The human ear perceives sound in a non-linear fashion, hence the decibel scale was developed. Because the decibel scale is based on logarithms, two noise sources do not combine in a simple additive fashion, but rather logarithmically. For example, if two identical noise sources produce noise levels of 50 dBA, the combined sound level would be 53 dBA, not 100 dBA. Noise levels from a particular source generally decline as distance to the receptor increases. Other factors, such as the weather and reflecting or barriers, also help intensify or reduce the noise level at any given location. A commonly used rule of thumb for roadway noise is that for every doubling of distance from the source, the noise level is reduced by about 3 dBA at acoustically "hard" locations (i.e., the area between the noise source and the receptor is nearly complete asphalt, concrete, hard -packed soil, or other solid materials) and 4.5 dBA at acoustically "soft" locations (i.e., the area between the source and receptor is normal earth or has vegetation, including grass). Noise from stationary or point sources is reduced by about 6 to 7.5 dBA for every doubling of distance at acoustically hard and soft locations, respectively. Noise levels may also be reduced by intervening structures — generally, a single row of buildings between the receptor and the noise source reduces the noise level by about 5 dBA, while a solid wall or berm reduces noise levels by 5 to 10 dBA. Regulatory Framework It should be noted that the project does not include any permanent noise sources after the completion other than periodical maintenance. City of Newport Beach General Plan Policy N1.8 describes significant noise impacts as below: Require the employment of noise mitigation measures for existing sensitive uses when a significant noise impact is identified. A significant noise impact occurs when there is an increase in the ambient CNEL produced by new development impacting existing sensitive uses. The CNEL increase is shown in Table 1.

Less than Significant Impact. A significant impact may occur if the proposed project would generate excessive noise that exceeds the noise level standards set forth in the respective General Plan Noise Elements and Noise Ordinances of the City of Newport Beach. Potential project noise impacts were assessed for 1) project construction to the adjacent noise sensitive receivers, 2) off- site noise impacts due to the project operation, and 3) on-site noise impact to the project site. It is concluded the impact would be less than significant. See details below. Construction Noise With regard to construction noise, the City's noise ordinance, Section 10.28.040 limits construction hours between 7:00 a.m. and 6:30 p.m. on any weekdays and between 8:00 a.m. and 6:00 p.m. on any Saturdays. It also prohibits construction activities on any Sundays and any federal holidays. It is assumed that construction would not occur outside of indicated hours and considered less than significant. Off -Site Noise After the completion of the project, there would be no noise generated sources in the project site. The potential noise generated activities would be occasional maintenance and repair activities throughout a year. It is assumed that maintenance and repair activities would occur within the Big Canyon Habitat Restoration and Water Quality Improvement Project 3-56 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist hours indicated in the City's noise ordinance, Section 10.28.040. Therefore, the impact would be less than significant. On -Site Noise The project site is identified as )pen Space in the City's General Plan, and it would remain as Open Space after the completion of the project. The City's General Plan Noise Element Policy N1.8, describes the threshold of significant impact based on the increase of noise levels over the existing noise levels. Since the ambient noise in the vicinity of the project site would remain unchanged after the completion of the project, the impact would be less than significant. b) Exposure of people to generation or excessive groundborne vibration or groundborne noise levels? Less than Significant with Mitigation Incorporation. Ground -borne vibration would be generated from the operation of heavy construction equipment at the project site, which could potentially affect the existing sensitive land uses surrounding the site. Once completed, there would be no operational sources causing ground -borne vibration. The closest off-site structure to the project construction area is the multi -family residential structure to the north adjacent to Jamboree Road. The distance to this structure is approximately 10 feet from potential construction equipment. Ground -borne vibration levels resulting from construction activities at the project site were estimated using data published by the Federal Transit Administration (FTA) in its Transit Noise and Vibration Impact Assessment (2006) document. The FTA has adopted vibration standards that are used to evaluate potential building damage impacts related to construction activities, which are shown in Table 3-11. TABLE 3-11 CONSTRUCTION VIBRATION DAMAGE CRITERIA Building Category PPV (in/sec) I. Reinforced -concrete, steel or timber (no plaster) 0.5 II. Engineered concrete and masonry (no plaster) 0.3 III. Non -engineered timber and masonry buildings 0.2 IV. Buildings extremely susceptible to vibration damage 0.12 SOURCE: FTA, 2006. In addition, the FTA has also adopted standards associated with human annoyance for ground - borne vibration impacts for the following three land -use categories: Vibration Category 1 — High Sensitivity, Vibration Category 2 — Residential, and Vibration Category 3 — Institutional. The FTA defines Category 1 as buildings where vibration would interfere with operations within the building, including vibration -sensitive research and manufacturing facilities, hospitals with vibration -sensitive equipment, and university research operations. Vibration -sensitive equipment Big Canyon Habitat Restoration and Water Quality Improvement Project 3-57 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist includes, but is not limited to, electron microscopes, high-resolution lithographic equipment, and normal optical microscopes. Category 2 refers to all residential land uses and any buildings where people sleep, such as hotels and hospitals. Category 3 refers to institutional land uses such as schools, churches, other institutions, and quiet offices that do not have vibration -sensitive equipment, but still have the potential for activity interference. The vibration thresholds associated with human annoyance for these three land -use categories are shown in Table 3-12. TABLE 3-12 GROUNDBORNE VIBRATION IMPACT CRITERIA FOR GENERAL ASSESSMENT Occasional Land Use Category Frequent Events' Events' Infrequent Events° Category 1: Buildings where vibration would 65 VdB' 65 VdB' 65 VdB' interfere with interior operations. Category 2: Residences and buildings where 72 VdB 75 VdB 80 VdB people normally sleep. Category 3: Institutional land uses with 75 VdB 78 VdB 83 VdB primarily daytime use. a "Frequent Events" is defined as more than 70 vibration events of the same source per day. b "Occasional Events' is defined as between 30 and 70 vibration events of the same source per day. C 'Infrequent Events' is defined as fewer than 30 vibration events of the same kind per day. d This criterion is based on levels that are acceptable for most moderately sensitive equipment such as optical microscopes. SOURCE: FTA, 2006. The various peak particle velocity (PPV) expressed in inches per second (in/sec) and root mean square (RMS) velocity expressed in VdB levels for the general construction equipment that would operate during the construction of the proposed project are identified in Table 3-13. Note that it is assumed that impact activities, such as pile driving, would not be used for this project.

Environmental Checklist Structure Damage Construction activities associated with the proposed project would have the potential to impact the surrounding off-site structures. The closest multi -family residential structure to the north is considered as non -engineered timber structure and is located approximately 10 feet from construction equipment. Therefore, the vibration impact threshold would be 0.2 in/sec PPV. The PPV value of a large bulldozer at 10 feet would be 0.352 in/sec PPV, which exceeds the impact threshold. This exceedance of the vibration level threshold for structural damage would be considered significant. Mitigation Measure N0I-1: Large construction equipment, such as large bulldozer and loaded trucks, shall be replaced with smaller equipment when the construction equipment is within 45 feet of the residential structure. Significance after Mitigation With the implementation of Mitigation Measure MM NOI-1, vibration impacts causing structural damage from construction activities would be less than significant. When a small bulldozer is used, the PPV value at 10 feet would be 0.119 in/sec PPV, which would be less than the impact threshold of 0.2 in/sec PPV. Human Annoyance The construction vibration could annoy people within a building. The vibration impact threshold for human annoyance at a residential structure would be 80 VdB. The RMS value of a large bulldozer at 10 feet would be 99 VdB which would exceed the human annoyance vibration threshold of 80 VdB. Therefore, the project construction activities could result in significant human annoyance vibration impacts. Mitigation Measure Implementation of Mitigation Measure NOI-1 is required. Significance after Mitigation With the implementation of Mitigation Measure MM NOI-1, vibration impacts causing human annoyance would be reduce to less than significant. The use of a small bulldozer would result in a RMS value at 10 feet of 70 VdB, which would be less than the impact threshold of 80 VdB. Operation Once construction activities have been completed, the potential vibration activities would occur when occasional maintenance is conducted by a large piece of equipment. Since the specific equipment is unknown, the potential impact could be considered significant. Mitigation Measure Implementation of Mitigation Measure N0I-1 is required. Big Canyon Habitat Restoration and Water Quality Improvement Project 3-59 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist Significance after Mitigation With the implementation of Mitigation Measure N0I-1, vibration impacts from operational activities associated with maintenance would be reduce to less than significant. C) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? Less than Significant Impact. After the completion of the project, there would be no noise generated sources in the project site. The potential noise generated activities would be occasional maintenance and repair activities throughout a year. It is assumed that maintenance and repair activities would occur within the hours indicated in the City's noise ordinance, Section 10.28.040. Therefore, the impact would be less than significant. d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? Less than Significant with Mitigation Incorporation. The project would temporary increase noise levels during construction phases. Construction of the proposed project would occur in multiple phases within a project boundary and is expected to last approximately five months. Construction phases and activities are presented in Table 3-14. TABLE 3-14 CONSTRUCTION SCHEDULE Phase Activity Duration Months Site preparation/ 1-2 weeks Month 1 Mobilization & Earthwork clearing/Grubbing Excavation and grading 2-3 weeks Months 1 and 2 Culvert extension 4-6 weeks Months 2 and 3 Drainage Structures and Piping Construction Dry weather diversion structures and 2-3 weeks Month 3 external piping Bioretention cell liner and piling 1-2 weeks Months 3 and 4 Water Quality System Bioretention cell media placement 1-2 weeks Month 4 Construction Bioengineering structure construction 1-2 weeks Month 4 OCSD Scope OCSD dosing station installation 4-6 weeks Months 3, 4, and 5 Restoration Site vegetation restoration 3-4 weeks Month 5 Construction activities occurring under each of these phases would require the use of heavy equipment (e.g., excavators, backhoes, loaders, tractors, etc.) along with the use of smaller power tools, generators, and other sources of noise. During each construction phase there would be a different mix of equipment operating and noise levels would vary based on the amount of equipment in operation and the location of each activity. As such, construction activity noise levels during each phase would fluctuate depending on the particular type, number, and duration of use of the various pieces of construction equipment. Big Canyon Habitat Restoration and Water Quality Improvement Project 3-60 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist Table 3-15 includes the list of construction equipment with quantity, usage per day, and estimated noise levels per phase. It should be noted that maximum noise levels associated with the construction equipment would only be generated when the equipment are operated at full power. Typically, the operating cycle for a piece of construction equipment would involve one or two minutes of full power operation followed by three or four minutes at lower power settings. As such, the maximum noise levels shown in Table 3-15 would only occur occasionally throughout the construction day. In addition to Table 3-15, hauling trucks would access the project site from Back Bay Drive and an access road through Big Canyon. Trucks would be very slow. However, trucks would be passing by within 100 feet of existing multi -family residential homes.

Noise levels for those equipment not included in this User's Guide are estimated based on similar equipment. SOURCE: ESA 2016. During the project's construction activities, the nearest and most notable off-site sensitive receptors to the construction site would be the existing multi -family residential uses to the north, which would be as close as 10 feet from the project boundary. Due to the use of construction equipment during the construction phases, the project would expose these sensitive receptors to increased exterior noise levels. Over the course of a construction day, the highest noise levels would be generated when multiple pieces of construction equipment are being operated concurrently. The City's noise ordinance, Section 10.28.040 limits construction hours to between 7:00 a.m. and 6:30 p.m. on any weekdays and between 8:00 a.m. and 6:00 p.m. on any Saturdays. It also prohibits construction activities on any Sundays and any federal holidays. Thus, the construction activities associated with the proposed project would be required to adhere to the applicable permitted hours of operation established under the City of Newport Beach's Noise Ordinance. However, although the proposed project's construction activities would only occur under the permitted hours allowed under the City of Newport Beach's Noise Ordinance, the proposed project would still expose the existing sensitive receptors located in proximity to the project site to increased exterior noise levels above existing ambient noise levels. It should be noted, however, that any increase in noise levels at the off-site sensitive receptors during project construction would be temporary in nature, and would not generate continuously high noise levels, although occasional single -event disturbances are possible. Nonetheless, because the temporary noise nuisance generated by the project's construction activities would constitute a substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project, this noise impact is considered to be potentially significant.

Environmental Checklist Mitigation Measures NOI-2: The construction contractor shall ensure proper maintenance and working order of equipment and vehicles and that all construction equipment is equipped with manufacturers approved mufflers and baffles. NOI-3: The construction contractor(s) shall endeavor to use quieter equipment as opposed to noisier equipment (such as rubber -tired equipment rather than track equipment), when feasible. Noisy equipment shall be switched off when not in use. NOI-4: Construction activities shall be scheduled so as to avoid operating several pieces of equipment simultaneously, which causes high noise levels, to the extent feasible. NOI-5: The construction contractor shall place all stationary construction equipment so that emitted noise is directed away from sensitive receptors nearest the project site. Significance after Mitigation Implementation of Mitigation Measures NOI-2 through NOI-5, which would require the implementation of noise reduction devices and techniques during construction at the project site, would reduce the noise levels associated with construction of the proposed project to the maximum extent that is technically feasible, and this reduction would result in less than significant noise impacts. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? No Impact. The project site is located approximately 2.3 miles south of the John Wayne Airport. However, the project site is not within the airport's Noise Impact Zones, as specified by the Airport Environs Land Use Plan (AELUP) for John Wayne Airport (ALUC, 2008). Further, the project would not increase the amount of people living or working in the area, and would therefore, not expose people residing or working in the area to excessive noise levels. f) For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? No Impact. There are no private airstrips in the vicinity of the proposed project. Further, the project would not increase the amount of people living or working in the area, and would therefore, not expose people residing or working in the area to excessive noise levels.

Environmental Checklist 3.13 Population and Housing No Impact. The proposed project would not increase the number of residents within the City. Project construction would require a total of about 8 employees per day that would be employed temporarily during construction, and these employees would not induce population growth within the City. The duration of the project construction would last approximately five months, and it would not result in population growth in the area due to the project's temporary activities lasting only five months. Therefore, the project would result in no direct or indirect impacts to population growth in the project vicinity. b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? No Impact. The project site is located on open space land that is a natural habitat for various plant and wildlife species. There is no existing housing on the project site, no displacement of existing housing and no required replacement housing. No impact would occur. C) Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? No Impact. The project site is located on open space land that is utilized as a natural habitat for various plant and wildlife species. The project would not increase the number of residents within the City.

No Impact. The Newport Beach Fire Department (NBFD) provides fire protection services for the entire City. The nearest NBFD fire station is Fire Station #3 located approximately 0.4 miles south of the project site at 868 Santa Barbara Drive. The proposed project would restore habitat, provide water quality features, and provide enhanced access to the project site for trail users. The proposed project could increase the use of the project area by increasing access and providing educational opportunities through the installation of interpretive signs along the trail. The project site could also provide learning opportunities for community and school groups. Although the project may increase the use of the project area, this increase would not result in a substantial number of trail users such that the fire department's service would be substantially affected. In addition, the enhancement of onsite access would allow the fire department improved access within the project site for emergencies. Because the proposed project is not altering the use of the project site (i.e., provision of trails), and the project would not substantially alter the number of trail users, the proposed project would not require the NBFD to provide new or physically altered facilities to serve the project site. Therefore, the implementation of the proposed project would result in no environmental impacts to new or physically altered fire department facilities because changes to these City facilities would not be required. Big Canyon Habitat Restoration and Water Quality Improvement Project 3-66 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist b) Police protection? No Impact. The Newport Beach Police Department (NBPD) provides local police services to the City of Newport Beach. The NBPD headquarters is located adjacent to NBFD Fire Station #3 at 870 Santa Barbara Drive. The proposed project would restore habitat, provide water quality features, and provide enhanced access to the project site for trail users. The proposed project could increase the use of the project area by increasing access and providing educational opportunities through the installation of interpretive signs along the trail. The project site could also provide learning opportunities for community and school groups. Although the project may increase the use of the project area, this increase would not result in a substantial number of trail users such that the police department's service would be substantially affected. In addition, the enhancement of onsite access would allow the police department improved access within the project site for emergencies. Because the proposed project is not altering the use of the project site (i.e., provision of trails) and the project would not substantially alter the number of trail users, the proposed project would not require the NBPD to provide new or physically altered facilities to serve the project site. Therefore, the implementation of the proposed project would result in no environmental impacts to new or physically altered police department facilities because changes to these City facilities would not be required. C) Schools? No Impact. The Newport -Mesa Unified School District (NMUSD) provides public educational services to the City of Newport Beach, as well as the City of Costa Mesa and other unincorporated areas of Orange County. The proposed project would not introduce new residents within the City. Therefore, the project would not increase the demand for school facilities. As a result, the proposed project would not require the NMUSD to provide new or physically altered school facilities. The project would result in no environmental impacts to new or physically altered school facilities because changes to school facilities would not be required. d) Parks? No Impact. The proposed project encompasses about 6 acres in the eastern portion of the 60 -acre Big Canyon Nature Park. The project site is designated as Open Space by the City General Plan, which is intended to "provide areas for a range of public and private uses to protect, maintain, and enhance the community's natural resources." The proposed project would enhance the recreational activities in the park by providing an extension of the existing trails to allow for pedestrian and bicycle travel. The official trail would allow access for the public to learn and enjoy the native habitats located within the park. The project's habitat restoration and access trails would enhance the quality of the park. The proposed project would not require the City to provide new or physically altered park facilities because these facilities would not be required to serve the project. Therefore, the implementation of the proposed project would result in no environmental impacts to new or physically altered park facilities.

Less than Significant Impact. The project site is assessable from Back Bay Drive and Jamboree Road by trail users as well as maintenance personnel. The implementation of the proposed project would result in an increase in traffic during construction activities and may result in minor increases in maintenance personnel trips during the operation of the project. During construction, approximately 8 employees will travel to the project site during the morning peak hour traffic period (i.e., prior to 9 am). Construction activities will require the use of haul trucks for vegetation and soil removal. The haul trucks would be used during the non -peak hours (i.e., after 9 am and prior to 4 pm). A maximum of 40 trucks per day during 6 hours each day would result in a maximum average of 7 trucks per hour.

Trucks exiting the project site would travel along the Big Canyon access road to Back Bay Drive to East Bluff Drive and then to Jamboree Road. The addition of 8 employee trips during the peak hour and an average of about 7 truck trips per hour during the non -peak hours would not result in substantial traffic effects at intersections or roadways in the project vicinity. b) Conflict with an applicable congestion management program, including, but not limited to, level of service standards and travel demand measures, or other standards established by the county congestion management agency for designated roads or highways? Less than Significant Impact. As stated above, the proposed project would result in a minimal amount of traffic trips to the surrounding street network. The applicable congestion management program is administered by the Orange County Transportation Agency (OCTA). According to the OCTA 2015 Congestion Management Program (CMP), the nearest CMP roadway is approximately 2 miles north of the project site at Jamboree Road and State Route 73. As stated above, the proposed project is anticipated to generate 8 employee trips during the peak hour and 7 truck trips during the non -peak hours. This level of traffic is considered minimal. According to the CMP Preparation Manual, a traffic impact analysis (TIA) is required for CMP purposes if a project generates 2,400 or more daily trips if the project does not directly access the CMP Highway System link, such as the proposed project (Orange County Transportation Authority, 2011). Because the project would generate a maximum of 40 trucks entering and 40 trucks exiting the site and up to 8 employee vehicles entering and 8 employees exiting the project site, the project would generate substantially fewer daily trips than the 2,400 or more daily trips that require a TIA to be prepared for CMP purposes. Therefore, the project would result in a less than significant impact on a CMP facility. C) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location, that results in substantial safety risks? No Impact. The implementation of the proposed project would include facilities that would not affect air traffic patterns. The nearest airport to the project site is John Wayne Airport which is located approximately 2.3 miles north of the project site. d) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? No Impact. The project site currently contains a maintenance access off of Jamboree Road. The proposed project includes a modified maintenance road access that is perpendicular to Jamboree Road. The proposed access would meet the City of Newport Beach design requirements for maintenance roads. In addition, construction vehicles are proposed to access Back Bay Drive. The current speed limit for vehicles on Back Bay Drive is 15 miles per hour. Construction vehicles associated with the proposed project would limit speeds on Back Bay Drive to 15 miles per hour to ensure traffic safety for pedestrians, bicyclists and equestrian users of the trail along Back Bay Drive. In addition, as part of a standard City procedure during public works projects, signs will be Big Canyon Habitat Restoration and Water Quality Improvement Project 3-71 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist posted along Back Bay Drive regarding the construction activities and duration. Therefore, the proposed project would not result in increasing hazards due to a design feature. e) Result in inadequate emergency access? No Impact. Project construction activities would be located on the project site and would not require any lane closures. In addition, project operational activities will not require lane closures or impact emergency access. The provision of additional trail segments on the project site would provide greater access to the project area, but would not adversely affect emergency access. Therefore, the project would not impact emergency access to the project site or areas in the vicinity of the project site. f) Conflict with adopted policies, plans, or programs regarding public transit, bicycle, or pedestrian facilities, or otherwise decrease the performance or safety of such facilities? No Impact. The implementation of the proposed project would not conflict with policies, plans or programs related to public transit, bicycle or pedestrian facilities. Back Bay Drive currently has public transportation facilities, including a one way vehicular pathway. The project construction vehicles would use the one-way vehicular pathway and limit their speeds to the existing 15 miles per hour limit.

Discussion a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? No Impact. The Regional Water Quality Control Board, Santa Ana Region, issued a National Pollutant Discharge Elimination System (NPDES) permit that implements federal and state law governing point source discharges and nonpoint source discharges to surface waters of the United States. Construction and operation of the proposed project includes a wastewater pipe that would allow selenium -concentrated water from seeps to be conveyed to the existing wastewater pipe located along Jamboree Road. The wastewater would be conveyed to the Orange County Sanitation District treatment facilities. The amount and frequency of discharged selenium wastewater would be nominal, and the proposed project would not exceed OCSD's wastewater treatment requirements of the Santa Ana Region of the Regional Water Quality Control Board. Thus, the project would not impact existing wastewater treatment requirements.

Environmental Checklist b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? No Impact. The proposed project would not require the construction of a new water or wastewater treatment facility or expansion of the existing treatment facilities serving the project vicinity. The project requires no potable water supply for the project site. The project would involve the extension of an existing sewer conveyance within the project site, but would not require the extension of any existing water or wastewater facilities off the project site. Therefore, the proposed project would result in no impact requiring the construction of water or wastewater treatment facilities. C) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? No Impact. The proposed project would not require the construction of new stormwater drainage facilities. The project itself includes the construction of a primary stormwater treatment structure to trap and pretreat contaminants prior to conveyance to the bioretention cell. The project would not require the addition of a storm drain conveyance or the expansion of any stormwater drainage facilities since the project aims to restore the natural habitat and improve water quality within the creek. With the implementation of these features, the proposed project would not require the construction of new storm water drainage facilities or expansion of existing facilities off site. Therefore, the project would result in no environmental effects from new storm water drainage facilities or expansion of existing facilities to serve the proposed project. d) Have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? No Impact. The City of Newport Beach's water supply is provided by the Municipal Water District of Orange County. The construction and operation of the proposed project requires no use of imported water supply from existing water resources. Thus, the project would result in no need for new or expanded water supply entitlements, and no impacts would occur. e) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? Less than Significant Impact. Wastewater collected by the Sanitary District is sent to the County Sanitation Districts of Orange County (County Sanitation) plants for treatment and disposal. Wastewater is treated at County Sanitation's treatment plants in Fountain Valley and Huntington Beach. According to County Sanitation's treatment plant operational data, the combined effluent treated at both plants is approximately 200 million gallons daily (average). County Sanitation operates under an NPDES ocean discharge permit issued by the California Regional Water Quality Control Board (OCSD, 2016). The project's increase in selenium Big Canyon Habitat Restoration and Water Quality Improvement Project 3-74 ESA /Project No. 130934 Final Initial Study / Mitigated Negative Declaration April 2016 3. Environmental Checklist wastewater would be infrequent and not be substantial. Project implementation would contribute a nominal amount of wastewater and would not cause the treatment plants' operating capacities to be exceeded. Therefore, the proposed project would result in a less than significant impact to wastewater treatment capacity. f) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? Less than Significant Impact. The project site would be served by the solid waste facilities and landfills that are operated by the Orange County Waste and Recycling (OCWR). The nearest landfill to the project location is the Frank R. Bowerman Sanitary Landfill in Irvine, and is the only landfill that serves the City of Newport Beach. The Bowerman Landfill is permitted as a Class III landfill to receive a daily maximum of 11,500 tons per day. Class III landfills accept only non -hazardous municipal solid waste for disposal; no hazardous or liquid waste can be accepted. It is currently estimated to operate with adequate capacity until 2053. The landfill is required to comply with numerous landfill regulations from federal, state and local regulatory agencies (OCWR, 2016). Project implementation would result in the need for disposal of debris from construction and maintenance activities. Solid waste removed from the project site would include dead or non- native vegetation. Debris would be removed with construction equipment and transported to the landfill by haul trucks. It is anticipated that the project's generation of solid waste would be at its greatest during initial construction activities due to the primary removal of non-native habitat vegetation. Thereafter, the project would result in minimal removal of dead vegetation during operational maintenance activities. Given the project's scale, it is anticipated that the specified landfill would have the adequate capacity to accommodate the project's waste disposal needs. Therefore, the project would result in a less than significant impact to landfill capacity. g) Comply with federal, state, and local statutes and regulations related to solid waste? No Impact. Construction and operation of the proposed project would result in the disposal of dead or non-native vegetation to the Frank R. Boweman Sanitary Landfill in Irvine. The disposal of vegetation would comply with federal, state, and local statutes related to solid waste. No impact to these regulations would occur with project implementation.

Less than Significant with Mitigation Incorporated. Construction activities associated with the proposed project could impact nesting birds, vegetation communities such as riparian and wetland habitat and could temporarily disrupt wildlife movement. These potential impacts to these biological resources would be significant. Construction activities could also impact historical or prehistorical resources. Although no resources are known to occur on the project site, there is a potential for unknown historical or prehistorical resources to be located on the project site based on resources found in the project vicinity. These potential unknown resources could be significantly affected. Mitigation Measures Implementation of Mitigation Measures BIO -1 through BI0-3, CR -1 and CR -2 is required.

Less than Significant with Mitigation Incorporated. Based on a review of the City of Newport Beach Cumulative Projects List, there are various projects in different planning stages that are located within two miles of the project site; however, only one project (one new residence) that is located upstream within Big Canyon of the project site. The various projects include an Autonation (about 2.0 miles from the site), Environmental Nature Center Preschool (about 1.7 miles from the site), condominium development at Newport Center Villas (about 1.0 mile from the site), mixed-use development at Back Bay Landing (about 1.5 miles from the site), Balboa Marina expansion (about 1.7 miles from the site), medical offices (about 1.7 miles from the site), a residence (about 0.4 mile from the site), construction of a clubhouse at Newport Beach Country Club (about 1.0 miles from the site), condominium units (about 0.6 mile from the site), and a commercial development (about 2.0 mile from the site). As discussed in Section 3 of this IS/MND, the proposed project would result in significant impacts to biological resources, cultural resources, vibration, and construction noise. The project would substantially contribute to potential cumulative impacts to each of these environmental components. As a result, the project's contribution to cumulative impacts associated with biological resources, cultural resources, vibration, and construction noise would be cumulatively considerable. Mitigation Measures Implementation of Mitigation Measures BIO -1 through BIO -3, CR -1 through CR -3, and NOI-1 through NOI-5 is required. Significance after Mitigation With the implementation of the above mitigation measures, the project's contribution to cumulative impacts associated with biological resources, cultural resources, vibration, and construction noise would be reduce to less than significant.

The project site is east of Upper Newport Bay and west and east of Jamboree Road and includes portions of Big Canyon Creek. The project includes the implementation of a creek and riparian habitat restoration, habitat creation and enhancement, a bioretention cell and storm water treatment wetland, dry -weather flow diversions, culvert improvements, and trail planning in the upper portion of the Big Canyon Nature Park. The project has several objectives, including: • Restore and Enhance Riparian Habitat • Improve Water Quality • Reduce Flood/Erosion/Sedimentation Damage • Encourage Public Participation and Provide Education • Provide Recreational Opportunities In order to meet these objectives, the proposed project includes the following elements: • Creek Restoration and Riparian Habitat Creation & Enhancement- The project proposes to conduct creek restoration activities that will include floodplain restoration, streambank stabilization and habitat restoration. Floodplain restoration and streambank stabilization activities will result in increased flood flow attenuation, stabilization of the north bank of the main channel of Big Canyon Creek, and creation of an active braided riparian floodplain. The north creek bank at the inlet will be stabilized using natural bioengineering techniques. Riparian habitat will be restored directly downstream of the floodplain restoration area through the removal of invasive trees, soil remediation to reduce plant -limiting sodium levels, and replacement with native riparian species. Riparian habitat creation activities will also be conducted directly to the southwest of the proposed water quality basin. This area will be graded down to allow for riparian trees to access existing groundwater. Riparian habitat enhancement will include removal of upstream and adjacent sources of Brazilian peppertree both east of Jamboree and north of the creek. • Stormwater Water Quality Treatment Bioretention Cell — The project includes the construction of a water quality treatment bioretention cell that will treat wet weather flows from Jamboree Road and reduce the storm drain -associated vector habitat in Big Canyon Creek. The basin will be vegetated with Coastal Sage Scrub (CSS) on the outer banks and vegetated with native riparian forbs, grasses and shrubs in the inner basin. These species will have the ability to sequester toxins and tolerate flooded conditions for limited periods of time. The basin will be periodically maintained per an approved Operation and Maintenance Plan. • Dry Weather Water Quality Selenium Reduction Measures — A dry weather flow diversion that re-routes flows of lower selenium concentration around identified sources of high selenium and return these better quality flows back into the creek will be constructed as part of this project. Dry weather flows will be diverted from an underground culvert on the east side of Jamboree Road and routed through an above ground pipe along the south bank of the creek and through the storm drain culvert under Jamboree Road. The pipe will discharge on the west side of Jamboree Road into the floodplain that will be graded as part of this project. Groundwater seeps that are sources of high selenium will be collected in a collection sump and diverted to the sanitary sewer. • Infrastructure Improvements - The Project will also be constructed in coordination with infrastructure improvements by the Orange County Sanitation District (OCSD). The improvements include the extension and improvement of the existing access road along the toe of slope along the west side of Jamboree Road. The access road improvements will be used access and maintain the sanitary sewer manhole located to the north of the existing culvert outfall. The construction of the access road to and over the existing culvert under Jamboree Road requires the extension of the culvert. A stilling pool will be located at the end of the culvert extension to dissipate hydraulic energy as the stormwater transitions from flow in the culvert and discharges to the re -graded floodplain. This stilling pool will be periodically maintained to remove sediment and vegetation. Water from the stilling pool will exit via a rip rap energy dissipater. OCSD will also install a permanent dousing station and access area located to the south of the proposed habitat creation area. • Community Access Improvements and Educational Opportunities — The extended access road will provide an official trail where the public can learn about and enjoy the native habitats. In addition, an 8' wide bicycle path connector will be installed that provides access directly from Jamboree Road. In addition, the maintenance road at the top of the water quality basin will also be used as a side viewing trail with interpretive signs installed. The public will cross from the south to the north side of the creek via the OCSD constructed turn around area over the culvert, and follow a footpath on the north side of the creek. The footpath on the north side of the creek will continue within the CSS habitat, following existing ad-hoc trails that will be expanded to approximately 8' wide. Trails allow for educational opportunities regarding water quality and creek restoration activities, and through the installation of signage and as -needed fencing, will keep the public out of sensitive habitats. Stormwater Wetland Basin Maintenance Standards General Requirements Maintenance is critical if stormwater wetland basins are to function as originally designed. A specific maintenance plan will be developed for the bioretention cell when the final design has been completed, outlining the schedule and scope of maintenance operations, as well as the documentation and reporting requirements. The following are general maintenance requirements: 1. The stormwater wetland basin should be inspected annually and inspections after major storm events are encouraged (wetland basin inspection and maintenance checklists will be developed specifically for the bioretention cell). Trash and debris should be removed as needed, but at least annually prior to the beginning of the wet season. 2. Site vegetation should be maintained as frequently as necessary to maintain the aesthetic appearance of the site and to prevent clogging of outlets, creation of dead volumes, and barriers to mosquito fish to access pooled areas, and as follows: ■ Vegetation, large shrubs, or trees that limit access or interfere with basin operation should be pruned or removed. ■ Slope areas that have become bare should be revegetated and eroded areas should be regraded prior to being revegetated. ■ Invasive vegetation, such as Alligatorweed (Alternanthera philoxeroides), Halogeton (Halogeton glomeratus), Spotted Knapweed (Centaurea maculosa), Giant Reed (Arundo donax), Castor Bean (Ricinus communis), Perennial Pepperweed (Lepidium latifolium), and Yellow Starthistle (Centaurea solstitalis) must be removed and replaced with noninvasive species. Invasive species should never contribute more than 25% of the vegetated area. For more information on invasive weeds, including biology and control of listed weeds, look at the "encycloweedia" located at the California Department of Food and Agriculture website at: http://www.cdfa.ca.gov/wma, or the California Invasive Plant Council website at: http://portal.cal-ipc.org/weedlist. ■ Dead vegetation should be removed if it exceeds 10% of area coverage. This does not include seasonal die -back where roots would grow back later in colder areas. Vegetation should be replaced immediately to maintain cover density and control erosion where soils are exposed. 3. Sediment buildup exceeding 6 inches over the storage capacity in the first cell should be removed. Sediments should be tested for toxic substance accumulation in compliance with current disposal requirements visual or olfactory indications of pollution are noticed. If toxic substances are encountered at concentrations exceeding thresholds of Title 22, Section 66261 of the California Code of Regulations, the sediment must be disposed of in a hazardous waste landfill. 4. Following sediment removal activities, replanting and/or reseeding of vegetation may be required for reestablishment. Maintenance Standards A summary of the routine and major maintenance activities recommended for the bioretention cell is shown in Table 1. Detailed routine and major maintenance standards listed in Table 2 and Table 3 are intended to be measures to determine if maintenance actions are required as identified through inspection. They are not intended to be measures of the facility's required condition at all times between inspections. These tables will be updated when the final design for the bioretention cell has been completed. Table 1. Wetland Basin Routine and Major Maintenance Guide Inspection and Maintenance Activities Summary Removal trash and debris U • Remove minor sediment accumulation near inlet and outlet structures • Stabilize/Repair eroded banks and fill in animal burrows if present • Remove any evidence of visual contamination from floatables such as oil and grease • Eliminate pests and conditions suitable for creating ideal breeding habitat • Install or repair pond liner to ensure that first cell maintains a permanent pool -Remove algae mats as often as needed to prevent coverage of more than 20% of pond surface • Mow berms routinely if applicable to maintain aesthetic appeal and to suppress weeds Remove dead, diseased, or dying trees and woody vegetation that interfere with facility maintenance. • Correct problems associated with berm settlement C • Repair berm/dike breaches and stabilize eroded parts of the berm QJ • Repair and rebuild spillway as needed to reverse the effects of severe erosion .� • Remove sediment build up in forebay and main basin area to restore original sediment holding c capacity • Regrade main basin bottom to restore bottom slope and eliminate the incidence of standing pools • Aerate compacted areas to promote infiltration if volume reductions are desired • Repair or replace gates, fences, flow control structures, and inlet/outlet structures as needed to maintain full functionality Table 2.

Rocks and pad depth are restored to design standards. Gate/Fence repaired. Frequency Monitoring The City will perform all necessary work to monitor the bioretention cell to demonstrate compliance with the success criteria established and described within this document. A separate sampling and analysis plan (SAP) will be prepared after the final design for the bioretention cell is complete. Annual Monitoring Reports will be prepared by the City and be available for review. Analytical sampling and testing shall be performed in accordance with accepted testing methods and approved testing laboratory specified in the SAP. The Monitoring Reports shall contain, at a minimum, the following information: ■ Name of Systems ■ Date of Report ■ Date of Monitoring ■ Name of Monitoring Professional ■ Analytical sampling and testing data to assess compliance with success criteria ■ Any noted alterations, impacts, surface water quality changes, apparent new attributes or indicators (positive or negative) which suggest significant change has occurred or might occur in the future ■ Any water pollution events such as reported spills and cleanup activities ■ Estimated plant species diversity, coverage, and plant community changes ■ Any noted wildlife activity on date of monitoring site ■ Any noted human impacts such as dumping or vandalism Long Term Management The City will maintain the bioretention cell as a quality, ecologically sound wetland and will be responsible to manage the bioretention cell in perpetuity in accordance with the terms of the long-term management plans. The City will use the bioretention cell in accordance with the following long-term management plan and to maintain the bioretention cell as functioning wetlands. In this capacity, allowable uses for the CWTS include: ■ Irrigation water ■ Ecological and educational laboratory ■ Water quality monitoring "facility" ■ Ecological monitoring "facility" ■ Marketing, promotional or demonstration example ■ Limited plant materials and aquatic resources harvesting location In any of these uses, public pedestrian (including that to accommodate the Americans with Disabilities Act or ADA) access will be allowed. As the science of wetlands and the maintenance of wetland systems continue to evolve, alterations in the long-term management plans may be anticipated. It will be the responsibility of the City to make any alterations. Report and Record Keeping The City will submit produce regular reports (frequency to be determined) describing the conditions of the bioretention cell and relating those conditions to the success criteria. The reports will contain the following: ■ Topographical map and as -built plans showing location of the bioretention cell. ■ Narrative summarizing the condition of the bioretention cell and all regular maintenance activities showing location of sampling plots, permanent photo points, location of transects, etc. ■ Results of vegetation survey including visual estimates of % overall cover and % cover by vegetation survey layer, species diversity, % exotic vegetation in each vegetation layer, survival rate of planted vegetation, an estimate of natural revegetation, a measure of the relative percentages of indicator status species groupings, and plant vigor as measured by evidence of reproduction. ■ Status of success criteria as noted in the Final Construction Plans and Specifications. ■ Results of analytical sampling and testing other surveys such as bird, macroinvertebrate, amphibian, reptile, and mammal surveys that may be done incidentally or by others (when results are provided). As -built reports will be generated at the conclusion of the construction of each phase of the development. These reports will confirm any changes that were required as a result of construction needs. Long-term Maintenance and Inspection Plan Regular maintenance is critical to the successful operation of the bioretention cell. Recommended operation and maintenance guidelines include: ■ Inspections and maintenance to ensure that water infiltrates into the subsurface completely (recommended infiltration rate of 72 hours or less) and that vegetation is carefully managed to prevent creating mosquito and other vector habitats. ■ Observe drain time for the design storm after completion or modification of the facility to confirm that the desired drain time has been obtained. ■ Schedule semiannual inspections for beginning and end of the wet season to identify potential problems such as erosion of the basin side slopes and invert, standing water, trash and debris, and sediment accumulation. ■ Remove accumulated trash and debris in the basin at the start and end of the wet season. ■ Inspect for standing water at the end of the wet season. ■ Trim vegetation at the beginning and end of the wet season to prevent establishment of woody vegetation and for aesthetic and vector reasons. ■ If erosion is occurring within the basin, revegetate immediately and stabilize with an erosion control mulch or mat until vegetation cover is established. ■ To avoid reversing soil development, scarification or other disturbance should only be performed when there are actual signs of clogging, rather than on a routine basis. Always remove deposited sediments before scarification, and use a hand -guided rotary tiller, if possible, or a disc harrow pulled by a very light tractor. These criteria will be updated when the final design for the bioretention cell is complete.

The project has several objectives, including creek and riparian habitat restoration, habitat creation and enhancement, stormwater treatment wetland, dry -weather flow diversions, culvert improvements, and trail planning in the upper portion of the Big Canyon Nature Park. This report describes the environmental setting of the project site and immediate vicinity, including plant communities, habitats, and sensitive biological resources that have been documented onsite or have the potential to occur onsite. In addition, the report includes an analysis of project -related construction and operational impacts to sensitive biological resources within the context of applicable environmental regulations, and provides recommendations to mitigate these effects. 1.1 Project Location and Land Use The project site is located within the city of Newport Beach, on a 10 -acre site within the eastern portion of the 60 -acre Big Canyon Nature Park (Figure 1). This area is east of Upper Newport Bay, adjacent to (east and west of) Jamboree Road, and includes a portion of Big Canyon Creek (Figure 2). Land uses within the project vicinity include residential development, a large golf course, a city maintenance facility, and commercial development. Onsite land uses include passive recreation, such as hiking on the public trail and/or access road that run through the site, and maintenance activities associated with the storm drain facilities. 1.2 Project Overview and Design The City of Newport (City) has contemplated restoration efforts within Big Canyon for over a decade. Currently, the City has funding for the restoration efforts that are part of Phases IA and IB (proposed project). Potential future restoration efforts within the 60 -acre Big Canyon Nature Park could also be proposed as a separate project, if future funding is available. The proposed project is currently being planned in coordination with a Resource Management and Maintenance Plan (RMMP) that is being prepared by the Irvine Ranch Conservancy under contract with the City of Newport Beach for the Big Canyon Nature Park. The RMMP provides a framework for restoration and recreational improvements in the Nature Park that will be consistent with Biological Resources Technical Report ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 SOURCE: City of Newport Beach, ESRI Big Canyon Restoration and Water Quality Improvement Project Biological Technical Report.

D130934 Figure 2 Project Vicinity Map recreational improvements in the Nature Park that will be consistent with the requirements of the Natural Community Conservation Plan (NCCP)/Habitat Conservation Plan (HCP) for the central and coastal subregion of Orange County (Orange County Central -Coastal NCCP/HCP) in the event the City elects to incorporate the Nature Park into the NCCP. Potential fixture restoration efforts within Big Canyon would also be coordinated with the RMMP. The proposed project has several objectives, including: • Restore and Enhance Riparian Habitat • Improve Water Quality • Reduce Flood/Erosion/Sedimentation Damage • Encourage Public Participation and Provide Education • Provide Recreational Opportunities To meet these objectives, the proposed project, as shown in Figure 3, includes the following elements. 1. Creek Restoration. The project proposes to conduct creek restoration activities, which will include floodplain restoration, streambank stabilization, and habitat restoration. The main channel is currently incised and is confined to the incised narrow creek bed. The channel will be realigned away from the eroding and undercut north bank into the center of the floodplain, and a new floodplain will be created on both banks. The north creek bank at the inlet will be stabilized using natural bioengineering techniques by adding encapsulated vegetated soil lifts, which will be planted with willows and other native vegetation to construct and protect the banks, and to provide erosion control. The existing area to the south of the creek would be lowered by approximately 6 feet to create a floodplain 2 to 3 feet above the low -flow channel to allow for frequent inundation during high-flow events. Willow brush mats will be placed over the cut bank and secured with biodegradable coir fabric, then secured with biodegradable rope and wooden stakes. Floodplain restoration and streambank stabilization activities will result in increased flood flow attenuation, stabilization of the north bank of the main channel, and creation of an active braided riparian floodplain. Riparian habitat will be restored directly downstream of the restored floodplain through the removal of invasive trees, soil modification to reduce plant -limiting sodium levels, and replacement with native riparian species. Under current conditions, invasive trees (mostly Brazilian peppertree) and an extensive understory of non-native forbs and grasses have been documented in the project area. In addition, soil testing results have indicated extremely high levels of sodium, boron, and sulfur in the soils, which inhibit growth of native plant species. The invasive plants are better able to compete under the poor soil conditions that are found within Big Canyon. The trees, forbs, and grasses will be aggressively removed as part of this project. Mature trees will be removed during mass grading and isolated individuals will be killed in place without soil disturbance. Following invasive plant removal, the soil will be amended to levels where native Biological Resources Technical Report 4 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 -02 440-251-05 ot Q Project Boundary Parcel /APN # o Invasive Trees Ash too Feet • • • 440-102-06 • • • e 440-102-07 - - - - -��- P5 ' Its 0 • 1/ • A, )%- -------- (D - , —A O' i� 0 0Q) Q • ® o �,���� • o '440-092-79 o W 0 • r�J 0 0/ 0 .� 440-25143 0 440-102-12 442-181-57 442-251-01 442-181-01 442-181-02 442-181-03 442-181-04 442-181-61 / 442-181-05 442-032-60 442-032-51 442-032-59 / Q Project Boundary Parcel /APN # Surveyed 0 Invasive Trees Ash Project Components Phase 1A: Riparian Habitat Restoration . • ® Staging/Storage Area • Canary Island date palm Riparian Habitat Restoration Area New Grading Features • Eucalyptus Phase 113: Mitigation Areas — Existing Sewer Features • Fig Riparian Habitat Creation Area Water Quality/Infrastructure Components • Goldenrain tree Riparian Habitat Enhancement Area 440-251-04 -- Water Line • Mexican fan palm Phase 113: Facilities/Roadways 442-181-13 Proposed Trails 0 Brazilian pepper Access Road and Infrastructure Improvement - - - 3.5 -foot wide Trail Bioretention Cell / 442-181-56- - 8 -foot wide Trail ® Dosing Station : — 15 -foot wide Trail SOURCE: Burns & McDonnell; Dudek; ESA Big Canyon Restoration and Water Quality Improvement Project Biological Technical Report.

Riparian Habitat Creation and Enhancement Activities. Riparian habitat creation activities will be conducted directly to the southwest of the proposed bioretention cell, in an area adjacent to the riparian forest restoration area that currently supports non-native grasses and forbs. This area will be graded down to allow the newly planted riparian trees to access existing groundwater. The discharge of the stormwater treatment wetland will also be routed to this area to provide for periodic inundation during storm events. In addition, this area will be subject to flooding during larger storm events, but will not pond water or create a habitat for mosquito larvae. Riparian habitat enhancement will include removal of upstream and adjacent Brazilian peppertrees (Schinus terebinthifolius) both east of Jamboree Road and north of the creek, which will greatly reduce the seed source for this highly invasive species. The created and enhanced habitat areas will provide the required mitigation for loss of riparian habitat resulting from implementation of the water quality and infrastructure components of this project. Stormwater Water Quality Treatment Bioretention Cell. The purpose of the stormwater treatment system, which consists of a primary treatment structure and a bioretention cell, is to improve water quality by reducing transportation -related pollutants currently discharged to Big Canyon Creek during storm events and to attenuate stormwater peak -flow discharge rates from the contributing Jamboree Road drainage area. A primary treatment structure would be constructed to receive runoff from existing stormwater inlets serving Jamboree Road. The purpose of this underground structure is to trap, contain, and pretreat trash, total suspended solids (TSS), and free oils prior to conveyance to the bioretention cell. Located adjacent to Jamboree Road, the primary stormwater treatment structure would be approximately 40 square feet in size and include three chambers. The first chamber would be designed to collect dense solids and trash (floatables); the second would collect sediment and finer solids; and the third would provide storage and delivery of dissolved phase constituents to the bioretention cell. Manhole access ports would be installed for periodic removal of trash and sediment from the three chambers. The bioretention cell will treat the stormwater flows that discharge from the primary stormwater treatment structure, and reduce the storm drain -associated vector habitat (i.e., ponded water that provides habitat for mosquito larvae) in Big Canyon Creek (see Figure 3). The basin of the bioretention cell will consist of (from top to bottom) layers of soil, sand, and gravel, underlain by an impermeable liner. The soil layer will be approximately 2 to 3 feet thick and would be underlain by a 6 -inch sand filter bed located between the bioretention soil and drainage gravel layer situated in the bottom of the bioretention cell. The bottom 12 -inch gravel drainage layer will form the base layer of the Biological Resources Technical Report 7 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 bioretention cell and will be underlain by a geotextile cushion. The entire bioretention cell will be underlain by a 60 -MIL high-density polyethylene liner. The outer banks of the bioretention cell will be vegetated with coastal sage scrub, and the inner basin will be vegetated with native riparian forbs, grasses, and shrubs. These species will have the ability to sequester toxins and tolerate flooded conditions for limited periods of time. The basin will be periodically maintained per an approved Operation and Maintenance Plan. Stormwater will flow via gravity from the primary stormwater treatment structure to the top of the subcells through a series of perforated and solid inflow polyvinyl chloride (PVC) pipes. Pollutants will be removed from stormwater as it flows down through the treatment media. Treated water will flow from the bottom of the bioretention cell through a series of PVC pipes into the newly created wetland habitat area located to the southwest of the bioretention cell, and from there will infiltrate into the ground and/or flow into Big Canyon Creek. 4. Dry -Weather Water Quality Selenium Reduction Measures. The purpose of the dry - weather flow diversion is to limit the contact between dry -weather flows with low selenium concentrations and the groundwater seepage flows that contain much higher selenium concentrations. Monitoring investigations conducted by the City in 2015 determined that seepage flows with high selenium concentrations occur in the creek on the east side of Jamboree Road between the proposed diversion and the entrance to the existing culvert. High selenium seeps also occur on the west side of Jamboree Road just downstream of the mouth of the existing culvert (City of Newport Beach 2015, unpublished data). The project proposes to passively collect these high selenium concentration seeps and direct them to the sanitary sewer. A dry -weather flow diversion will re-route the flows of lower selenium concentration around identified sources of high selenium and return these better quality flows back into the restored creek. The dry - weather flows will be diverted from an underground culvert on the east side of Jamboree Road and routed through an above -ground pipe along the south bank of the creek and through the storm drain culvert under Jamboree Road. The pipe will discharge on the west side of Jamboree Road into the floodplain that will be graded as part of this project. The estimated seepage flows are anticipated to be less than 10% of the total current dry - weather flows in Big Canyon Creek. Therefore, approximately 90% of the current dry - weather flows will be returned to the creek. Diverting the high selenium seepage flows into the sanitary sewer will substantially reduce in -stream selenium concentrations in the downstream creek flowing through the restoration area. 5. Infrastructure Improvements. The project will also be constructed in coordination with infrastructure improvements by the Orange County Sanitation District (OCSD). The improvements are shown in Figure 3 and include the extension and improvement of the existing access road along the toe of slope along the west side of Jamboree Road. The access road improvements will be used to access and maintain the sanitary sewer manhole located to the north of the existing culvert outfall. The construction of the access Biological Resources Technical Report 8 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 road to and over the existing culvert under Jamboree Road requires extension of the culvert. A concrete stilling basin will be located at the end of the culvert extension to dissipate hydraulic energy as the stormwater transitions from flow in the culvert and discharges to the regraded floodplain. This stilling basin will be periodically maintained to remove sediment and vegetation. Water from the stilling basin will exit via a rip -rap energy dissipater. OCSD will also install a permanent automatic chemical -dosing station and access area near the proposed habitat creation area. The dosing station consists of a 12 -foot -high 8 -foot -diameter tower that would be constructed on a 20 -foot by 20 -foot pad, and a gravel access road as needed to access the station. Native plants will be planted around the facility. The station would be maintained on a monthly basis. Community Access Improvements and Educational Opportunities. The extended access road will provide an official trail where the public can learn about and enjoy the native habitats. In addition, an 8 -foot -wide bicycle path connector will be installed to provide access directly from Jamboree Road. The maintenance road at the top of the bioretention cell will also be used as a side viewing trail with interpretive signs installed. Visitors using this trail will cross from the south to the north side of the creek via the OCSD-constructed turnaround area over the culvert and follow a footpath on the north side of the creek. The footpath on the north side of the creek will continue within the coastal sage scrub habitat, following existing ad hoc trails that will be expanded to approximately 42 -inches wide. Trails allow for educational opportunities regarding water quality and creek restoration activities and, through the installation of signage and as - needed fencing, will keep the public out of sensitive habitats. This plan is consistent with ongoing efforts planned for the Big Canyon Watershed in consultation with the City, environmental organizations including the Newport Bay Conservancy and Irvine Ranch Conservancy, and the appropriate regulatory agencies. Biological Resources Technical Report 9 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 This page intentionally left blank Biological Resources Technical Report 10 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 2.0 METHODOLOGY 2.1 Literature and Database Review Pertinent literature resources were reviewed by Environmental Science Associates (ESA) prior to conducting field surveys to determine if special -status biological resources occur or are known to occur within the vicinity of the project area. Literature sources included Big Canyon Creek Historic Tidal Wetlands Conceptual Restoration Plan, Upper Newport Bay (CCI 2004), and Big Canyon Creek Restoration Project Phase II Feasibility Study (WRA 2007). The following biological resource databases were also queried: U.S. Fish and Wildlife Service (USFWS) Information, Planning, and Conservation System (IPaC), California Department of Fish and Wildlife (CDFW—formerly California Department of Fish and Game) California Natural Diversity Database (CNDDB) (CDFW 2015), and California Native Plant Society (CNPS) Inventory of Rare and Endangered Plants (CNPS 2015). Database queries included all reported occurrences within the Newport Beach U.S. Geological Survey (USGS) 7.5 -minute quadrangle map (quad) in which the project site is located, and all adjacent USGS quadrangles. In addition, Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California (Dudek 2015) was reviewed after all field surveys were completed, as this report was not available until November of 2015. A list of potentially occurring special -status species and sensitive natural communities was developed for the project site based on the database search results and evaluated. Potentially occurring special -status species were defined as having a geographic range and habitat requirement similar to those found on, or within the vicinity of, the project site, and thus having the potential to occur. Available background information, including USGS topographic maps, U.S. Department of Agriculture soil survey data (MRCS 2015), National Wetland Inventory maps, and current and historical aerial photographs were used in conjunction with Geographic Information System (GIS) data to characterize soils and to map vegetation communities, and to identify any USFWS- designated critical habitat boundaries or CDFW Natural Community Conservation Planning areas. 2.2 Biological Resource Surveys General Biological Resources Survey and Constraints Assessment A general biological resources survey was conducted within an area that included the area of potential direct impacts plus a buffer to capture potential indirect impacts to biological resources. Biological Resources Technical Report 11 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 The survey was conducted on foot by ESA biologist Rosanne Humphrey on March 12, 2015, to identify potential biological resources onsite and potential constraints associated with the implementation of the proposed project. Special attention was paid to habitats having the potential to support sensitive biological resources (e.g., special -status species and sensitive natural communities). Aerial photography and global positioning system (GPS) technology was used to accurately locate any sensitive biological resources encountered. All plant and wildlife species observed during site surveys were identified and recorded into a field notebook. Wildlife species were identified during the field reconnaissance by sight and call or other evidence of presence such as tracks, nests, scat, and remains and with use of binoculars and taxonomic keys where appropriate. Plant taxonomy followed Baldwin et al. (2012).Vertebrate taxonomy followed Crother (2015) and CalHerps (2015) for amphibians and reptiles, the American Ornithologists' Union for birds (AOU 2015), and Wilson and Reeder (2005) for mammals. Vegetation Mapping Vegetation mapping was conducted on March 12 and December 16, 2015, by ESA biologist Rosanne Humphrey. Vegetation communities were characterized based on the presence of dominant plant species and were delineated within the project area. In addition, during the surveys, a habitat evaluation was conducted to determine the potential for each habitat area to support sensitive native species. Vegetation communities were initially mapped directly on aerial photographs and then digitized in ArcGIS. Vegetation community classification and descriptions were determined according to the Orange County Habitat Classification System (Jones and Stokes 1993, Gray and Bramlet 1992) to be consistent with the Orange County Central -Coastal NCCP/HCP and previous vegetation mapping (CCI 2004, WRA 2007). Each vegetation community was delineated based on the dominant plants observed onsite following CDFW's Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Natural Communities (CDFG 2009). In addition, vegetation alliances based on the CDFW Manual of California Vegetation (Sawyer et al. 2009), a higher resolution classification system, were delineated by Dudek in 2015. Vegetation alliances within each OCHCS vegetation community are described in Section 3. Unique classifications were developed for those land cover types not addressed by either classification system based on field observations of dominant species. The analysis of potential wildlife habitat linkages (i.e., wildlife migration corridors) on the project site or immediate vicinity was based on the conditions documented during the field reconnaissance surveys, as well as information compiled from literature and analysis of physical barriers observed on aerial photographs. This information was used to identify whether the project site and immediate vicinity could be used as an important wildlife movement corridor connecting large open space areas located upstream and downstream from the project site. The discussions in this report related to wildlife movement are intended to focus on areas within the project boundaries, immediate vicinity, and general region (project area). Biological Resources Technical Report 12 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 Jurisdictional Assessment ESA biologist Julie Fontaine conducted site visits on March 12 and 18, and December 15, 2015, to evaluate potentially jurisdictional features within the project area, including waterways and associated habitats potentially subject to U.S. Army Corps of Engineers (Corps), CDFW, Regional Water Quality Control Board (RWQCB), and California Coastal Commission (CCC) regulations. The purpose of the jurisdictional assessment was to identify regulated wetlands and waters of the United States and the State of California within the project area. Prior to field surveys, a desktop analysis was conducted to obtain contextual information relevant to the project area. ESA conducted a review of available background information pertaining to the project, geography, and topography prior to conducting the jurisdictional delineation in March 2015. A site map was generated with available aerial photographs, and potentially jurisdictional features were identified and marked with lines and GPS coordinates to assist in field verification. Soil types mapped within the project area were consulted prior to field efforts to target areas with potentially hydric soils. In addition, the following published and grey literature were reviewed and consulted: • 1996 National List of Vascular Plant Species that occur in Wetlands (USFWS 1996). • 2006 U.S. Army Corps of Engineers Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region. • Field Guide for Wetland Delineation (1987 Corps Manual) prepared by the Wetland Training Institute (WTI 1999). • A Field Guide to Lake and Streambed Alteration Agreements (CDFG 1994). • USFWS Definition of Wetlands adopted by CCC. (Cowardin et al. 1979.) The delineation was conducted in accordance with the Arid West Supplement to the 1987 Wetlands Delineation Manual, which reflects the required methods by the Corps as well as using the CCC definition of wetlands since the project falls within the Coastal Zone. In addition, CDFW riparian habitat was mapped as jurisdictional based upon the presence of hydrophytic vegetation to the dripline of the riparian vegetation. The CCC definition was met if one or more wetland parameters (soil, hydrology, and/or vegetation) were met. Appendix A provides the full jurisdictional delineation report, including methodologies and results. California Rapid Assessment Method Survey A Riverine California Rapid Assessment Method (CRAM) assessment was conducted by ESA biologists Rosanne Humphrey (CRAM Practitioner) and Alanna Bennett on December 16, 2015, following the Riverine Wetlands Field Book, Version 6.1 (CWMW, 2013). The purpose of the assessment was to evaluate the pre -project condition of Big Canyon Creek within the project area. One Assessment Area (AA) was delineated west of Jamboree Road. The AA extends from Biological Resources Technical Report 13 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 approximately 25 meters downstream of the outflow to 100 meters downstream, and encompasses the associated riparian vegetation along Big Canyon Creek. The width of the AA varies from approximately 12 to 30 meters. The following wetland attributes were assessed: Buffer and Landscape Context, Hydrology, Physical Structure, and Biotic Structure. Each attribute is based on the values of individual metrics. A rating of A, B, C, or D was given for each metric pursuant to the Riverine Wetlands Field Book, and then converted to a numeric value (A=12, B=9, C=6, and D=3). These numeric values were then used to calculate attribute scores and overall CRAM scores. Appendix B provides the full pre -project CRAM report, including methodologies and results. Focused Species Surveys Rare Plant Survey A rare plant survey was performed by ESA biologist Rosanne Humphrey on March 12, 2015, following the Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Natural Communities (CDFG 2009). The entire project area plus a buffer area was assessed for the presence of rare plant species. The full rare plant survey report is included in Appendix C. Coastal California Gnatcatcher Focused surveys were performed for the federally threatened California gnatcatcher (Polioptila californica californica) on March 27, April 3, and April 17, 2015, by ESA biologists Dallas Pugh (TE -79192A-1) and Alanna Bennett. The surveys were conducted pursuant to the most current USFWS survey protocol (USFWS 1997). A total of three surveys were conducted between 6:00 AM and 12:00 PM at least 7 days apart within all suitable habitat in the project area. Recorded vocalizations were played to elicit a response if birds were not readily detected. All observations were recorded (including time, number of individuals, and sex), and the coordinates of the observation were recorded with a hand-held GPS unit. The full protocol survey report for the California gnatcatcher is included in Appendix D. Least Bell's Vireo Focused surveys were performed for the state and federally endangered least Bell's vireo (Vireo bellii pusillus) on March 27, April 3, and April 17, 2015, by ESA biologists Dallas Pugh and Alanna Bennett. The survey methods were consistent with the most current USFWS survey protocol (USFWS 2001), except for the number of survey visits. A total of three surveys were conducted between 6:00 AM and 11:00 PM at least 10 days apart within all suitable riparian habitat in the project area. Recorded vocalizations were played to elicit a response if birds were not readily detected. All observations were recorded (including time and number of individuals), and the coordinates of the observation were recorded with a hand-held GPS unit. Although the protocol requires a total of eight survey visits between April and July, only three survey visits were conducted as a result of the project timeline. It was anticipated that Dudek would be Biological Resources Technical Report 14 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 conducting the entire eight -visit protocol survey; therefore, the results of both ESA's and Dudek's 2015 least Bell vireo surveys are included in this biological technical report (see Section 3). ESA's protocol survey report for least Bell's vireo is included in Appendix E. 2.3 Survey Limitations Focused species surveys were done early in the spring to accommodate project scheduling constraints. Because of the restrictive project timeline, many of the plants onsite were not yet in bloom during rare plant surveys. In addition, as discussed previously, only three site visits for the least Bell's vireo surveys were conducted; however, Dudek performed rare plant surveys full protocol surveys for the coastal California gnatcatcher and least Bell's vireo throughout the Big Canyon Nature Park, and these results will be discussed in Section 3. Biological Resources Technical Report 15 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 This page intentionally left blank Biological Resources Technical Report 16 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 3.0 ENVIRONMENTAL SETTING 3.1 Regional Setting The project site is located in Orange County near the coastline within a drainage that runs into upper Newport Bay, and eventually to the Pacific Ocean. Significant regional geographic features around the area include the peninsular ranges to the northeast and south, and the Pacific Ocean to the southwest. Eleven major watersheds traverse the county, transporting water from the surrounding mountains and deserts to the Pacific Ocean (OCPW 2014). Dense urban development occurs within the general area surrounding the project site in all directions. The project site is located within the Big Canyon Watershed, which consists of approximately 1,062 acres that drain to the Upper Newport Bay Ecological Reserve in the city of Newport Beach (Figure 1). Big Canyon Creek, which drains the watershed, is one of the few perennial streams that discharges to Upper Newport Bay, with a sustained dry -weather flow of approximately 0.4 cubic feet per second. The creek flows from southeast to northwest through Big Canyon Nature Park, ultimately draining into Upper Newport Bay (Figure 2). Big Canyon is the only natural, undeveloped portion of the Big Canyon Creek Watershed, and the only significant remaining natural canyon on the east side of Newport Bay. The climate in the region is Mediterranean, with dry summers and moderately wet winters; however, the region has experienced severe drought conditions over the past few years. The region lies in the semi-permanent high-pressure zone off the eastern Pacific Ocean, resulting in a mild climate tempered by moderate onshore winds, but is occasionally interrupted by periods of hot weather, winter storms, or Santa Ana winds; however, these interruptions are seasonal and do not generally affect the region for extended periods of time. Plant communities typically found within the coastal plains of the region include a mosaic of xeric habitats including sage scrub, grassland, and chaparral, with occasional riparian or woodland habitat associated with riverine or other aquatic features. Some creeks in the region are perennial; however, many are intermittent or ephemeral. Estuarine areas are influenced by tidal flows and may also be affected by dry season flows due to urban runoff. These habitats are known to support a wide variety of common plant and wildlife species, as well as many special - status species protected by federal, state, and local regulations. 3.2 Topography The project area is characterized topographically by steeply sloping bluffs and a narrow, moderately sloped floodplain; slopes range in elevation from 20 to 75 feet above mean sea level, Biological Resources Technical Report 17 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 and the canyon creek ranges in elevation from below mean sea level to 25 feet above mean sea level. A perennial stream identified as Big Canyon Creek traverses the project area and supports degraded riparian habitat. 3.3 Soils The U.S Department of Agriculture NRCS maps Upper Big Canyon Creek and the surrounding area as Sorrento Loam and Tidal Flats (SSURGO online database) (Figure 4). Tidal flats are remnant map units from before the time that the hydrology of the system was altered. The habitat is no longer tidally influenced but does retain the high salt content within the soil. Despite being altered, the soil exhibited hydric characteristics in the emergent marsh habitat. Areas containing predominantly Brazilian Peppertree did not exhibit hydric soil characteristics either in the Tidal Flats soils or the Sorrento loam soils. The Sorrento loam (fine -loamy, mixed, superactive, thermic Calcic Haploxerolls) occurs on alluvial fans and floodplains, originating from sedimentary rocks. It is not a hydric soil. The project area is generally quite disturbed. The area has been degraded as the result of decades of dredging spoils from the bay and dumping onsite; the quality of soils throughout the site is generally very poor as a result. There are six soils classes within the project area according to the Natural Resources Conservation Service (NRCS) (2015). Each soil type in the project vicinity is described below and shown in Figure 4. Balcom Clay Loam Balcom clay loam 30 to 50 percent slopes soils are located in a small portion along the eastern side of the northern border of the site. This soil class is well -drained with moderate to moderately slow permeability and a range of low to high runoff. Most commonly found vegetation on this soil series is annual grasses and mustard. Balcom clay loam soils have the potential to support clay specialist sensitive plant species. Anaheim Clay Loam Anaheim clay loam 30 to 50 percent slopes soils are located throughout most of the southern portion of the site. The soil ranges from slightly acidic to slightly alkaline and is well -drained. Runoff is rapid to very rapid and permeability is moderate to moderately slow. The vegetation found on this soil series is most often brush, annual grasses, and forbs. Anaheim clay loam soils have the potential to support clay specialist sensitive plant species. Sorrento Loam Sorrento loam 2 to 9 percent slopes soils are located throughout the central and northern portion of the site. Sorrento soils are found in alluvial fans and consist of very deep, well -drained soils with negligible to medium runoff and moderate to moderately slow permeability.

D130934 Figure 4 Soils commonly found on this soil consists mostly of annual grasses and forbs, and sycamores (Platanus sp.) along drainageways. Myford Sandy Loam Myford sandy loam thick -surface 2 to 9 percent slopes soils are located just outside of the project boundary to the north, southwest and southeast. Myford soils are deep, well -drained soils, runoff is moderate to rapid, and permeability is very slow. Annual grasses, forbs, and low -growing brush are the best suited vegetation to grow in soils within the Myford series. Saline coastal tidal flats are located on a small portion of the site in the northwest corner. Tidal flats occur on the border of a saline body of water with fluctuating water levels. These soils are important as they support transitional vegetation between terrestrial and marine habitats, providing fodder, shelter, and protection for local wildlife. Forbs, grasses, and vines are commonly found associated with tidal flats. Tidal flats are remnant map soil units from before the time that the hydrology of the system was altered. The habitat is no longer tidally influenced but does retain the high salt content within the soil. Cieneba Sandy Loam Cieneba sandy loam 30 to 75 percent slopes eroded soils are located in a small area of the northwest portion of the site. Cieneba soils are very shallow, fast -draining soils, with low to high runoff and rapid permeability. Chaparral, oak trees, and annual grasses are most commonly associated with this soil series. San Emigdio Fine Sandy Loam San Emigdio fine sandy loam moderately fine substratum 0 to 2 percent slopes soils are located in a small portion of the northwestern corner of the site. This soil series consists of deep, well - drained soils occurring within floodplains and fans; runoff is very low and permeability is moderately rapid. Annual grasses and forbs are commonly associated with this series. 3.4 Vegetation Communities Throughout much of the project area, the vegetation is highly disturbed; non-native plant species intermixed with native plant species is characteristic of the project area. Even within coastal sage scrub vegetation communities, non-native annuals cover the ground space between native shrubs, and within the southern riparian forest, Brazilian peppertree (Schinus terebinthifolius) and other invasive tree species are dispersed throughout much of the forest. As a result, much of the site is a mosaic of different types, levels of disturbance, and status of succession, rather than distinct, Biological Resources Technical Report 20 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 well-defined habitat types. Vegetation communities are mapped in Figure 5. The vegetation communities are described below according to the Orange County Habitat Classification System (Jones and Stokes 1993, Gray and Bramlet 1992). Each description includes a list of the California vegetation alliances (Sawyer et al. 2009) that are found within that vegetation type. Acreages of each vegetation community in the project area are summarized in Table 1. TABLE 1 ACREAGES OF VEGETATION COMMUNITIES Vegetation Community Acres State Rank' Southern Riparian Forest (SRF) 4.00 S.3.2 Alkali Meadow (AM) 0.10 S2.1 Coastal Sage Scrub (CSS) 1.53 S3.1 Non -Native Grassland (NNG) 2.83 S4 Disturbed (Existing Access Roads and Trails) 0.40 None Ornamental (ORN) 0.78 None Developed (DEV) 0.04 None Grand Total 9.67 CDFW state rank denotes the rarity and endangerment of an vegetation type within the state as follows: S2 = 2,000-10,000 acres; S2.1 = very threatened S3 = 10,000-50,000 acres; S3.1 = very threatened; S 3.2 = threatened S4 = Apparently secure within California; this rank is clearly lower than S3 but factors exist to cause some concern; i.e. there is some threat, or somewhat narrow habitat. No threat rank. Southern Riparian Forest Southern riparian forest occurs along streams and rivers, and is characterized by a dense canopy cover of western sycamore (Platanus racemosa), cottonwood (Populus spp.), mature willows (Salix spp.), and an understory of mulefat and small willows. Typically, trees in this community are mature and have closed, or nearly closed, canopies. A total of 4.00 acres of southern riparian forest were mapped within the project area, which is the most abundant community onsite. This vegetation community occurs throughout most of the central and north -central region of the project area, following the streambed, as well as in a small, isolated patch near the east -central region of the project area. It is a closed canopy forest dominated by Brazilian peppertree and arroyo willow (Salix lasiolepis). For the most part, there is little undergrowth near the center; however, non-native fortis are abundant along the edges where the sun is able to penetrate to the ground. The peppertrees occur throughout the southern riparian forest community (see Figure 5). These trees are most likely volunteers from the peppertrees planted as ornamentals on the hills above the project area and upstream, east of Jamboree Road. Other tree species in this community include blue elderberry (Sambucus nigra ssp. caerulea), Shamel ash (Fraxinus udehi), Mexican fan palm (Washingtonia robusta), and Canary Island date palm (Phoenix canariensis). Mugwort (Artemisia douglasiana) and garden nasturtium Biological Resources Technical Report 21 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 SOURCE: ESA, ESRI; Dudek Big Canyon Restoration and Water Quality Improvement Project Biological Technical Report. D130934 Figure 5 Biological Resources (Tropaeoleum majus) show prevalence throughout the understory, and pride of Madera (Echium candicans) is common on the northern and eastern edge of the forest. One California vegetation alliance was mapped by Dudek (2015) within the southern riparian forest. Peppertree or Myoporum Groves Semi -Natural Stands is typically dominated or co - dominated by Brazilian peppertree, Peruvian peppertree (Schinus molle), or myoporum (Myoporum laetum), which are all highly invasive non-native tree species. The rest of this area was mapped as Arroyo Willow Disturbed Mapping Unit, which is not recognized by the CDFW Natural Communities List (CDFG 2010), but was used to differentiate areas dominated by arroyo willow, but characterized by areas of disturbance. Alkali Meadow Alkali meadow is characterized by a dense to somewhat open distribution of perennial grasses and shrubs in alluvial slopes, salty grasslands, and alkali seeps. Soil within the community is moist, fine -textured, and alkaline. Plant species are typically low -growing and few in number, blooming from late spring to early fall. Species commonly associated with alkali meadow include yerba mansa (Anemopsis californica), sedge species (Carex spp.), rush species (Juncus spp.), saltgrass (Distichlis spicata), alkali sacaton (Sporobolus airoides), and alkali cord grass (Spartina gracilis). A total of 0.10 acre of alkali meadow was mapped within the northwest region of the project area. The dominant plant species onsite is Alkali heath (Frankenia salina) dominates this community in the project area. Other species include pickleweed (Salicornia subterminalis) and saltgrass (Distichlis spicata), as well as an abundance of wild radish (Raphanus sativus) and non-native grasses. The majority of this habitat type in the project area, which occurs in an opening within the riparian forest, was mapped as part of the Arroyo Willow Disturbed Mapping Unit by Dudek (2015). The rest was mapped as Alkali Heath Marsh Alliance. Diegan Coastal Sage Scrub Diegan coastal sage scrub is characterized by a variety of low, aromatic shrubs and soft -woody subshrubs, many of which are drought -deciduous. These species are typically most active in the winter and early spring, going dormant during the dry summer months. Although the species composition of the vegetation community varies substantially depending abiotic factors (slope, aspect, distance to the coast, soils, etc.) and successional stage, this community is often characterized by California sagebrush (Artemisia californica), flattop buckwheat (Eriogonum fasciculatum), California encelia (Encelia californica), black sage (Salvia mellifera), and white sage (Salvia apiana). Other common species include lemonadeberry (Rhus integrifolia), laurel sumac (Malosma laurina), and deerweed (Acmispon glaber). Diegan coastal sage scrub generally occurs in dry areas on steep, south -facing slopes. The shrub canopy is typically more open than in Biological Resources Technical Report 23 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 chaparral habitat, resulting in patches of bare ground, with native grasses or herbaceous species interspersed between shrubs. A total of 1.53 acres of highly disturbed Diegan coastal sage scrub were mapped in small isolated patches in the project area. One area consists of a row of tall lemonadeberry shrubs along Jamboree Road, presumably planted as ornamentals to provide a screen between the road and the habitat. The area between Jamboree Road and the riparian scrub habitat occurs in a mosaic within the non-native grassland and other habitat types and consists of scattered individual sagebrush and coyote brush (Baccharis pilularis) shrubs with a dense understory of non-native forbs and grasses, such as mustards (Brassica spp. and Hirschfeldia incana), and brome grasses (Bromus spp.). Larger patches occur on the south -facing slopes below residential development on the north side. These areas are also highly disturbed, consisting of isolated sagebrush shrubs with patches of bare ground and slender leaf ice plant (Mesembryanthemum nodiflorum) and crystalline ice plant (Mesembryanthemum crystallinum), as well as a variety of non-native grasses and forbs, such as mustards, bromes, and sweet clovers (Melilotus spp). At the bottom of the slope, there is a small patch that consists of a monoculture of California sagebrush. Three California vegetation alliances were mapped within the coastal sage scrub areas by Dudek (2015). Lemonadeberry Alliance was mapped along the western side of Jamboree Road; Coyote Brush Scrub -California Sagebrush Alliance was mapped in the low-lying areas between Jamboree Road and the riparian scrub habitat; and California Sagebrush Alliance was mapped along the south -facing slopes on the northern portion of the project area. Non -Native Grassland Non-native grasslands are characterized by a dense to sparse cover of annual non-native grasses, which can reach up to one meter in height. Often, native annual forbs are dispersed among the non-native grasses, and are sometimes more abundant that the grasses. Germination occurs in the late fall and flowering and seed -set occurs in the spring; plants dry out and die -off in the dry summer months. Non-native grasslands typically support wild oat (Avena spp.), brome (Bromus spp.), filaree (Erodium spp.), and other non-native annual species. This community usually occurs in areas of previous disturbance, sometimes associated with grazing and fallow agricultural fields, located on fine -textured, well -drained soils that are moist in winter but very dry during summer months. A total of 2.83 acres of non-native grassland were mapped within the project area on the north - facing slopes along the southwestern border of the project area, in the low-lying areas between Jamboree Road and the riparian forest habitat, and in a few small areas on the south -facing slopes in the southern portion of the project area. The dominant species within the project area are black mustard (Brassica nigra), field mustard (Brassica rapa), shortpod mustard (Hirschfeldia incana), and wild radish. Non-native grassland was mapped as Upland Mustards Semi -Natural Stands by Dudek (2015). These areas are characterized by weedy, upland mustard species. Biological Resources Technical Report 24 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 Disturbed Disturbed areas include lands that have been significantly disturbed as the result of human activity. These lands provide little to no habitat value for wildlife; the vegetation present in these areas is negligible. Onsite, disturbed areas consist of an unpaved access road, which runs for 800 feet north to south near the western region of the site, and connects with Jamboree Road on the southern end. A short, off -shoot road about 300 feet long leads to the center of the southern riparian bluff. On the northern border of the site, a small trail along the bottom of the slope. This trail is for public access and is approximately 900 feet long within the project area. A total of 0.40 acre of disturbed land cover was mapped. These areas were mapped as Developed — Disturbed or Barren Mapping Unit. This land cover type is not recognized by the CDFW Natural Communities List (CDFG 20 10) because it is unvegetated. Ornamental Ornamental is a land cover type characterized by parks and ornamental plantings, consisting of introduced species of trees and other landscaping that is actively managed. This land cover type was also used by Dudek (2015). A total of 0.78 acre of ornamental land cover is present within the project area along the northern and southwestern borders; both areas are atop manufactured slopes, the result of adjacent landscaping to residential developments. The small area east of Jamboree Road is also composed almost entirely of ornamental trees, mostly Brazilian peppertrees. This is likely one of the seed sources for the peppertrees in the native riparian habitat downstream. Other species within this land cover type include Sydney golden wattle (Acacia longifolia), myoporum, eucalyptus (Eucalyptus spp.), ash, and pride of Madera. Developed Developed areas contain commercial or residential buildings, paved roads, and landscaped surfaces and generally do not support natural plant or wildlife species. Only one small area (0.04 acre) was mapped as developed. This area is east of Jamboree road in a portion of the project boundary that overlaps with the golf course. Biological Resources Technical Report 25 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 3.5 CRAM Assessment Results Figure 6 shows the location of the AA within the project area. The overall CRAM score for the AA within the project area was fairly low (42). In addition, each individual attribute scored fairly low as well, ranging from 38 for the Buffer and Landscape Context and Physical Structure, to 50 for the Hydrology attribute (Table 2). The fourth attribute, Biotic Structure, scored 44. Some of these scores are reflective of the highly urbanized environment of the project area, which affects the volume and velocity of dry -season and wet -season flows, and the high levels of disturbance, which affect the physical and biological structure of Big Canyon Creek. Many of these environmental conditions, such as dense development, cannot be changed; however, the project proposes a number of components, including habitat restoration and water quality improvement, that are expected to greatly improve the function and habitat value of the stream channel, riparian habitat, and surrounding upland habitat. It is recommended that a CRAM assessment be conducted after the project is complete, especially after the restoration has become self- sustaining, to measure the functional improvement of the habitat within the project area. The full CRAM report is included in Appendix B.

D130934 Figure 7 Jurisdictional Areas 3.7 Flora A total of 90 plant species were observed within the project area during the 2015 rare plant surveys and other site visits. Of these species, 33 were (37%) native and 57 species (63%) were non-native. Although the project area includes a large amount of highly disturbed areas that are invaded with non-native and invasive species, some moderate quality riparian habitat is also present, which can provide habitat for a variety of wildlife species, such as riparian birds and raptoras. A full plant species compendium is included in Appendix F. Special -status plant species are discussed in Section 3.11. 3.8 Wildlife Species Although much of the project area is composed of disturbed riparian forest, non-native grassland, and low -quality coastal sage scrub, a variety of wildlife species were nevertheless observed within the project area. Most of the species observed are highly adapted to urban environments, such as mourning dove (Zenaida macroura), American crow (Corvus brachyrhynchos), house finch (Haemorhous mexicanus), house sparrow (Passer domesticus), Cooper's hawk (Accipiter cooperi), and Anna's hummingbird (Calypte anna). It is likely that the area also supports urban - adapted mammals, such as raccoon (Procyon lotor), opossum (Didelphis sp.), and coyote (Canis latrans).Other species observed are adapted to riparian habitats, including common yellowthroat (Geothlypis trichas), pacific -slope flycatcher (Empidonax difficilis), and yellow warbler (Setophaga petechia). A full plant species compendium is included in Appendix F. Special -status plant species are discussed in Section 3.11. 3.9 Special -Status Biological Resources 3.9.1 Special -Status Vegetation Communities Sensitive natural communities are designated as such by various resource agencies, such as the CDFW, or in local policies and regulations. These communities are generally considered to have important functions or values for wildlife and/or are recognized as declining in extent or distribution, and are considered threatened enough to warrant some level of protection. Sensitive natural communities include those that are identified in the CDFW List of California Natural Communities (CDFW, 2010). The CDFW state rank denotes the rarity and endangerment of a vegetation type within the state as described on the next page. In addition, riparian habitats and coastal sage scrub are considered sensitive habitats and are protected by the CCC through the Local Coastal Plan (LCP). Biological Resources Technical Report 30 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 State Rank S 1 = less than 1,000 individuals OR less than 2,000 acres S2 = 2,000-10,000 acres S3 = 10,000-50,000 acres S4 = Apparently secure within California; this rank is clearly lower than S3 but factors exist to cause some concern; i.e. there is some threat, or somewhat narrow habitat. NO THREAT RANK. S5 = Demonstrably secure to ineradicable in California. NO THREAT RANK. Threat Rank .1 = very threatened .2 = threatened .3 = no current threats known Based on the state and threat ranks, three sensitive communities occur within the project area: southern riparian forest, alkali meadow, and coastal sage scrub. 3.9.2 Potentially Occurring Special -Status Species "Special -status" species are plants and animals that are listed under the California Endangered Species Act (CESA) or Federal Endangered Species Act (FESA), as well as species protected under other regulations and species that are considered sufficiently rare or sensitive by the scientific community to be considered rare. Special -status species are categorized as follows: • Species listed or proposed for listing as threatened or endangered, or are candidates for possible future listing as threatened or endangered, under CESA or FESA. • Species protected under the federal Bald and Golden Eagle Protection Act. • Species that meet the definitions of rare or endangered under CEQA (State CEQA Guidelines § 15380). • Plants listed as rare under the California Native Plant Protection Act (LAPPA; Fish and Game Code § 1900 et seq.). • Plants considered by the CNPS to be rare, threatened, or endangered in California. 0 Species covered under an adopted Natural Community Conservation Plan (NCCP)/Habitat Conservation Plan (HCP). 0 CDFW Special Animals and wildlife species of special concern. • Wildlife fully protected in California (Fish and Game Code § 3511, 4700, and 5050). • Avian species protected by the federal Migratory Bird Treaty Act (MBTA). Biological Resources Technical Report 31 ESA / 130934 Big Canyon Restoration and Water Quality Project January 2016 Based on the literature/database review and field reconnaissance, 133 special -status species were evaluated for their potential to occur in the project site or immediate vicinity, based on the following definitions: Unlikely: The project site or immediate vicinity do not support suitable habitat for a particular species, and therefore the species is unlikely to occur within the area. Low Potential: The project site or immediate vicinity only provide low -quality or very limited habitat for a particular species. In addition, the known range for a particular species may be outside of the project site or immediate vicinity. Moderate Potential: The project site or immediate vicinity provide suitable habitat for a particular species. However, the habitat or substrate may be limited or the desired vegetation assemblage or density is less than ideal. High Potential: The project site or immediate vicinity provides high-quality suitable habitat conditions for a particular species. Additionally, known populations of the species may occur in the project site or immediate vicinity. Present: The species was observed within the project site during relevant biological surveys or other project visits. A total of 69 special -status plant species were assessed for their potential to occur within the study area. Eight species have a moderate potential to occur and three have a high potential to occur. The remaining 59 species were assessed as having either an unlikely or low potential to occur. A total of 64 special -status wildlife species were assessed for their potential to occur in the area; 12 species have a moderate potential to occur, 6 species have a high potential to occur, and 2 species were observed during various biological surveys. The remaining 44 wildlife species were determined to have an unlikely to low potential to occur. Tables 4 and 5 include the species that were considered to have a moderate to high potential to occur, as well as those that were observed onsite during the 2015 surveys. Appendix G provides a complete list of the 133 species that were evaluated, and includes the sensitivity status, habitat preferences, potential to occur onsite, and justification. Sensitive species occurrences from the CDNNB database within 2 km of the site are shown in Figure 8 (note that the assessment of potentially occurring species included documented occurrences within the Newport Beach topographic quadrangle and all surrounding quadrangle maps; however, the map in Figure 8 is zoomed in to focus on coastal habitats).

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property. Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed. Sites listed in bold italics are in multiple databases. Unmappable (orphan) sites are not considered in the foregoing analysis.

The Risk Management Program Rule (RMP Rule) was written to implement Section 112(r) of these amendments. The rule, which built upon existing industry codes and standards, requires companies of all sizes that use certain flammable and toxic substances to develop a Risk Management Program, which includes a(n): Hazard assessment that details the potential effects of an accidental release, an accident history of the last five years, and an evaluation of worst-case and alternative accidental releases; Prevention program that includes safety precautions and maintenance, monitoring, and employee training measures; and Emergency response program that spells out emergency health care, employee training measures and procedures for informing the public and response agencies (e.g the fire department) should an accident occur.

Manufactured gas sites were used in the United States from the 1800's to 1950's to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.

Assessment of the impact of contaminant migration generally has two principal investigative components: 1. Groundwater flow direction, and 2. Groundwater flow velocity. Groundwater flow direction may be impacted by surface topography, hydrology, hydrogeology, characteristics of the soil, and nearby wells. Groundwater flow velocity is generally impacted by the nature of the geologic strata. TC4524155.2s Page A-1 GEOCHECe - PHYSICAL SETTING SOURCE SUMMARY GROUNDWATER FLOW DIRECTION INFORMATION Groundwater flow direction for a particular site is best determined by a qualified environmental professional using site-specific well data. If such data is not reasonably ascertainable, it may be necessary to rely on other sources of information, such as surface topographic information, hydrologic information, hydrogeologic data collected on nearby properties, and regional groundwater flow information (from deep aquifers). TOPOGRAPHIC INFORMATION Surface topography may be indicative of the direction of surficial groundwater flow. This information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted.

The City received three comment letters from State agencies (Governor's Office of Planning and Research, California Department of Fish and Wildlife, and Santa Ana Regional Water Quality Control Board) and verbal comments from the City of Newport Beach Planning Department on the content of the IS/MND. This Response to Comments Letter provides responses to each comment within the comment letters and to each verbal comment. The responses in this Response to Comments Letter clarify, amplify, and expand on the adequate analysis and significance conclusions that were already set forth in the Proposed MND. CEQA Guidelines Section 15073.5 makes clear that such clarifications and amplifications are appropriate under CEQA and do not require recirculation of the Proposed MND. Specifically, Section 15073.5 states: (a) A lead agency is required to recirculate a negative declaration when the document must be substantially revised after public notice of its availability has previously been given pursuant to Section 15072, but prior to its adoption. Notice of recirculation shall comply with Section 15072 and 15073. (b) A "substantial revision" of the negative declaration shall mean: (1) Anew, avoidable significant effect is identified and mitigation measures or project revisions must be added in order to reduce the effect to insignificance, or (2) The lead agency determines that the proposed mitigation measures or project revisions will not reduce potential effects to less than significance and new measures or revisions must be required. (c) Recirculation is not required under the following circumstances: (1) Mitigation measures are replaced with equal or more effective measures pursuant to Section 15074.1. (2) New project revisions are added in response to written or verbal comments on the project's effects identified in the proposed negative declaration which are not new avoidable significant effects. (3) Measures or conditions of project approval are added after circulation of the negative declaration which are not required by CEQA, which do not create new significant environmental effects and are not necessary to mitigate an avoidable significant effect. Robert Stein April 25, 2016 Page 2 (4) New information is added to the negative declaration which merely clarifies, amplifies, or makes insignificant modifications to the negative declaration. (d) If during the negative declaration process there is substantial evidence in light of the whole record, before the lead agency that the [project, as revised, may have a significant effect on the environment which cannot be mitigated or avoided, the lead agency shall prepare a draft EIR and certify a final EIR prior to approving the project. It shall circulate the draft EIR for consultation and review pursuant to Sections 15086 and 15087, and advise reviewers in writing that a proposed negative declaration had previously been circulated for the project. As set forth in more detail in this Response to Comments Letter, none of the clarifications or amplifications set forth herein change the significance conclusions presented in the Proposed MND or substantially alters the analysis presented for public review. Furthermore, the Proposed MND circulated for public review was fully adequate under CEQA such that meaningful public review was not precluded. Thus, the clarifications provided in this response to comments do not constitute substantial revisions that might trigger recirculation. The City of Newport Beach has evaluated the comments received on the Proposed MND for the proposed Big Canyon Habitat Restoration & Water Quality Improvement Project and has prepared responses to the comments received. The comments and responses are provided in Attachment A. Sincerely, Michael E. Houlihan, AICP Principal Managing Associate Enclosure: Attachment Attachment A Response to Comments Following are the responses to the comments that were received during the 30 -day public review period for the Proposed MND for the proposed Big Canyon Habitat Restoration & Water Quality Improvement Project. Responses that resulted in revisions and clarifications of the information in the MND are identified as underlined text for additions and stFik^ eut f,.F deleted text None of the revisions or clarifications change the significance of the conclusions provided in the Proposed MND or substantially altered the analysis presented for public review.

State of California — Natural Resources Agency EDMUND G. BROWN JR_, Governor r DEPARTMENT SOF FISH AND WILDLIFE CHARLTON H. BONHAM, Director South Coast Region 3883 Ruffin Road San Diego, CA 92123 (858) 467-4201 www.wiidlife ca.gov April 4, 2016 Mr. Robert Stein City of Newport Beach Public Works Department 100 Civic Center Drive Newport Beach, CA 92660 rsteiii@newpertbeachca.gov newpertbeachca.gov Subject; Comments on the Notice of Intent to Adopt a Mitigated Negative Declaration for the Big Canyon Habitat Restoration and Water Quality Improvement Project (SC H# 2016031011) Dear Mr, Stein. The California Department of Fish and Wildlife (Department) has reviewed the above - referenced Notice of Intent to Adopt a Mitigated Negative Declaration (MND) for the Big Canyon Habitat Restoration and Water Quality Project, dated February 2016. The City of Newport Beach (City) requested comments on the MND by April 4, 2016, The following statements and comments have been prepared pursuant to the Department's authority as Trustee Agency with jurisdiction over natural resources affected by the project (California Environmental Quality Act (CEQA] Guidelines § 15386) and pursuant to our authority as a Responsible Agency under CEQA Guidelines section 15381 over those aspects of the proposed project that come under the purview of the California Endangered Species Act (CESA; Fish and Game Code § 2050 et seq.) and Fish and Game Code section 1600 et seq. The Department also administers the Natural Community Conservation Planning (NCCP) program. The City is a participating landowner under the Central/Coastal Grange County NCCPIHabitat Conservation Plan (HCP). Additionally, the Department owns and manages the Upper Newport Bay Ecological Reserve (UMBER). The City has deliberated restoration efforts within Big Canyon for more than 10 years and various Department staff have been involved in previous planning efforts. Currently the City has funding for Phases IA and IB, the proposed project. As more funding becomes available, it is anticipated that Phase I will precede potential future restoration efforts in the remaining downstream areas of the watershed. The proposed project site is located on a 10 -acre site within the eastern portion of the 6D -acre Big Canyon Nature Park, including a portion of Big Canyon Creek; east of Upper Newport Bay; adjacent to Jamboree Road. Big Canyon is the only natural, undeveloped portion of the Big Canyon Watershed and the only significant remaining natural canyon on the east side of Newport Bay. Directly downstream of the project area, the lower 15 -acre portion of Big Canyon Nature Park is part of the UMBER. Big Canyon Nature Park is located in the Upper Newport Bay State Marine Conservation Area and is part of southern California's coastal estuarine environment. In addition, Newport Bay discharges adjacent to the Newport Coast Area of Special Biological Significance. On-site land uses of the project site include utilization of the multipurpose trail/access read that runs through the site, as well as maintenance activities associated with storm drain facilities. Conserving California's Wifd(fe Since 1870 Mr. Robert Stein City of Newport Beach Public Works Department April 47 2016 Page 2 of 6 Project activities in Phases IA and IB, include creek restorationlstabiiization, riparian habitat creation and enhancement, installation of a stormwater water quality treatment bioretention cell, implementation of dry weather water quality selenium reduction measures. infrastructure improvements including the extension and improvement of the existing access roads, a public trail along the toe of slope along the west side of Jamboree Road, and the installation of an 8 - foot wide bicycle path connector that will provide access directly from Jamboree Road. Topographically, the pro}ect site is characterized by steeply sloping bluffs and a narrow, moderately sloped floodplain. Habitat types present on site include southern riparian forest (4.00 acres), coastal sage scrub (1.53 acres), non-native grassland (2.83 acres), ornamental (0.78 acre), disturbed areas/roads (D.40 acre), and alkali meadow (0.10 acre); non -natives occur prolifically throughout the site in all habitat types. The draft MND states that, based on the California Natural Diversity Data Base, Big Canyon Creek Historic Tidal Wetlands Conceptual Restoration Plan Upper Newport Bay (CCI 2004), Big Canyon Creek Restoration Project Phase II Feasibility Study (WRA 2007), and biological surveys conducted by Environmental Science Associates (ESA) in early spring 2015, no NCCPIHCP covered species are located within the project area. However, three California Species of Special Concern were observed on site within the riparian forest habitat, including Cooper's hawk (Accipiter cooperrr), yellow -breasted chat (Ictena virens), and yellow warbler (Setophaga petec,hiaO. The Department offers the following comments and recommendations to assist the City in avoiding or minimizing potential project impacts on biological resources. Proposed Project Phase IA and IB The draft MND's Project Description states, "The proposed project is currently being planned in coordination with a Resources and Recreation Management Plan (RRMP) being prepared by the Irvine Ranch Conservancy under contract with the City of Newport Beach for the Big Canyon Nature Park" (page 2-1). in order to ensure that the RRMP is in compliance with the NCCPIHCP as stated, we request that the Department and United States Fish and Wildlife Service be included in the development and review of the RRMP. The draft MND does not include an analysis of what vegetation types would be established and persist, given that a portion of the surface flow will be captured (i.e., removed from this portion of the riparian system) and routed directly to a water treatment basin. The final MND should include a detailed discussion concerning anticipated vegetation types in relationship to change in surface water flow, including whether or not the impacts of changed surface flow on vegetation types are significant without mitigation. 3. The Department is aware that least Bell's vireo (Vireo beNir pusillus), a conditionally covered species under the NCCPIHCP, have been seen within the project area in 2014 and 2015 and may be supported by the site. Mitigation Measure BIO -1 partially addresses impacts to nesting birds; however, because of the sensitive nature of the habitat, the potential for least Bell's vireo to occur, and the project site's proximity to other conserved open space, we recommend amendments be made to this measure to include the following a. Clearing, grubbing, or/and excavation activities in potentially suitable nesting habitat is not allowed during the nesting season for least Bell's vireo (March 15 -August 31). If these activities will occur during that time frame, the Department recommends the M. Mr. Robert Stein City of Newport Beach Public Works Department April 4, 2016 Page 3of6 project proponent seek appropriate take authorization under CESA prior to implementing the project. Appropriate authorization may include an incidental take permit (ITP) or a consistency determination in certain circumstances (Fish and Game Code §§ 2080. 1, 2081, subds. (b), (c)). Therefore, BIO -1 should be amended to specify the potential notification requirements under CESA; b. we request that protocol surveys for least Bell's vireo, along with any other reports and maps of significant impacts to native vegetation/foraging habitat be shared with the Department; c. that a daily monitor be present on site should construction continue into the nesting bird season; and, d. the Department recommends that nesting surveys described be conducted no later than three (3) days prior to construction. Longer periods between nesting surveys and the start of construction activities increase the likelihood that nesting activity can occur undetected, which may increase direct impacts to special status and passerine species such that they are significant without further mitigation. 4. The draft MND states that the areas defined with the current jurisdictional delineation report will be regulated pursuant to Section 1600 et seq. of the Fish and Game Code (pages 3-23). The mitigation ratios and acreages referenced to offset temporary and permanent impacts stated in Mitigation Measures BIO -2 and 131O-3 may not be adequate to satisfy obligations under the Project's Streambed Alteration Agreement. Based on habitat type and quality, the Department will evaluate the adequacy of ratios at the time the project applicant formally submits a streambed notification package to the Lake and Streambed Alteration Program of the Department. 5. Mitigation Measure B1O-3 proposes the preparation and implementation of a mitigation plan which would restore areas temporarily impacted by construction activities and subsequently mitigate permanent impacts (page 3-23). The mitigation measure does not state who will be implementing this plan, when the measures would be implemented, or how the mitigation would be approved and conducted. The mitigation measure should include monitoring and reporting on the effectiveness of the measure at compensating project disturbance that may result in permanent habitat conversion to non-native plant habitat. Additionally, for the purposes of review under CEQA, the final MND should include revisions to include a designated representative at the City or their designee to oversee restoration, commitment to a timeframe to when mitigation would occur, and the proposed mitigation plan. 6. The environmental analysis does not clearly define whether noise generated during project activities was considered as a potential significant impact to biological resources, particularly with regard to avian species. Generally, average hourly noise levels above 60 decibels are considered to negatively impact nesting birds and other wildlife. The final MND should fully describe BMPs (i.e., barriers/walls, sound muffling devices on mechanized equipment, etc.) that would be implemented to attenuate project -related construction and operational noise levels in excess of ambient levels. Setbacks should be established at the edge of sensitive habitats on and off site to avoid or minimize noise -related impacts on wildlife, particularly avian species. In addition to evaluating potential direct impacts, a more detailed discussion of Indirect impacts to biological resources from noise resulting from the proposed project should be analyzed in the final MND. IN ME : • 4 ALS Mr. Robert Stein City of Newport Beach Public Works Department April 4, 2016 Page 4 of 6 Polyphagous Shot Hole Borer (PSHB) is an invasive beetle that carries three fungi: Fusarium euwailaceae, Graphium euwallaceae, and Parecremonium pembeum. The adult female (1.8-2.5 mm long) tunnels galleries into the cambium of a wide variety of host trees, where it lays its eggs and propagates the fungi species (above) for the express purpose of feeding its young, These fungi cause Fusarium Dieback disease, which interrupts the transport of water and nutrients in at least 38 tree species. With documented occurrences throughout Southern California, including the San Diego Creek drainage (University of California, Riverside (UCR); http://eskalenlab.ucr.edu/distribution.htmi), the spread of PSHB could have significant impacts in Orange County ecosystems: specifically for those under analysis in the draft MND (e.g. riparian habitat)- Therefore, with regard to PSHB, we recommend the final MIND include the following.- a. ollowing: a. A thorough discussion of the direct, indirect, and cumulative impacts that could occur from the potential spread of PSHB as a result of project activities; b. an analysis of the likelihood of the spread of PSHB as a result of the invasive species` proximity to above referenced activities, c. figures within the MND and Biological Resources and Technical Report should depict potentially sensitive or susceptible vegetation communities within the project area, the known occurrences of PSHB within the project area, and PSHB's proximity to above referenced activities, and d. a mitigation measure or measure(s) within the final MND that describe Best Management Practices (BMPs) which bring impacts of the project on the spread of PSHB below a level of significance. Examples of such BMPs include: i, education of on-site workers regarding PSHB and its spread; ii. reporting sign of PSHB infestation, including sugary exudate ("weeping") on trunks or branches and PSHB entry/exit-hales (about the size of the tip of a ballpoint pen), to the Wildlife Agencies and UCR's Eskalen Lab; in. equipment disinfection; iv. pruning in infested areas where project activities may occur; v. avoidance and minimization of transport of potential host tree materials; vi. chipping potential host materials to less than one inch (1"<), prior to securely delivering to a landfill; vii. chipping potential host materials to less than one inch (I"r), prior to composting on- site; viii, solarization of cut logs; and/or ix. burning of potential host tree materials; and x. reporting suspected infestations to the Eskalen Lab at UC Riverside (eskalenlab, ucr.edu). Please refer to UCR's Eskalen lab website for more information regarding PSHB http://eskalenlab.ucr,eduiavocado.htmi. 1 Mr, Robert Stein City of Newport Beach Public Works Department April 4, 2016 Page 5 of 6 Potential Future Restoration Efforts While the Department supports habitat restoration and water quality improvements within Big Canyon, we are concerned that the future project phases may directly and/or cumulatively impact Department property and the larger Big Canyon Watershed. While the draft MND discusses and analyzes activities associated with Phases IA and IB, there is also mention of future restoration efforts (page 2-3). The Biological Resources Technical Report prepared by ESA in 2016 (Appendix C) references prior Big Canyon Restoration project documents, including Big Canyon Creek Historic Tidal Wetlands Conceptual Restoration Plan Upper Newport Bay (CCI 2004) and Big Canyon Creek Restoration Project Phase 11 Feasibility Study (WRA 2007). The Pre -Construction Riverine Cahfornia Rapid Assessment Method (CRAM) Report, prepared by ESA (December 30, 2015, and found in Appendix B in Appendix C described above) states (page 3), "The Project is part of a larger proposed multi -phased Big Canyon Watershed Restoration and Coastal Adaption Project (Phases I and II) that has been planned for over a decade It further states, "Phase I, the current Project, includes the implementation of a creels and riparian habitat restoration, stormwater treatment wetland: dry weather flow diversions, culvert improvements, and trail planning in the upper portion of the Big Canyon Nature Preserve. Phase IIA is also part of the current Project and continues to build on the benefits to be achieved through Phase I". The Department issued a letter to the City dated June 9, 2008, stating that we did not concur with the 2007 Big Canyon Restoration Project, citing impacts to salt marsh bird's beak (Chloropyron maritimum) and the net loss of fresh water marsh habitat. Accordingly, the Department questions whether the City has amended or altered the overall objective, scope, or proposed execution of the Big Canyon Restoration project from the 2007 Big Canyon Restoration project and the plans the Department reviewed in 2008. The Department recommends that the final MND specifically state that potential future restoration efforts and/or additional phases will undergo independent CEQA review. Additionally, we offer the following comments regarding the above -referenced potential future restoration efforts: a. The Department does not concur with any realignment of Back Bay Drive, nor with any Big Canyon restoration activities which may take Department land; b. we do not agree that converting fresh water ponds into marsh habitat will remediate issues with selenium; to the contrary, converting selenium -laden sediment areas to fresh water marsh habitat potentially exposes the sensitive species that would utilize such habitats to selenium bio -accumulation, such as light-footed Ridgway's rail (Rallus obsoletus levipes; formerly light-footed clapper rail), and c, instead, the Department recommends that the threat of bio -accumulation of selenium, protection of sensitive species, flood control, and vector control could be more effectively achieved through the conversion of fresh water ponds to riparian habitat Should such actions be considered in future phases, we recommend that these issues are directly analyzed and discussed to ensure that impacts are considered less than significant under CEQA. We appreciate the opportunity to comment on the draft MND for B-11 Mr. Robert Stein City of Newport Beach Public Works Department April 4, 2416 Page 6 of 6 this project and to assist the City in further minimizing and mitigating project impacts to biological resources. The Department requests an opportunity to review and comment on any response that the City has to our comments and to receive notification of the forthcoming hearing date for the project (CEQA Guidelines; §15573(e)). If you have any B-11 questions or comments regarding this letter, please contact Jennifer Edwards at (858) 457-2717 or via email at jennifer.edwards@wildlife.ca.gov. Sincerely, ` F Gall K. Sevrens Environmental Program Manager South Coast Region ec. Christine Medak (U.S. Fish and Wildlife Service) Scott Morgan (State Clearinghouse) Letter B: California Department of Fish and Wildlife, Gail Sevrens, April 4, 2016 Response to Comment B-1 This comment requested that the California Department of Fish and Wildlife (CDFW) and the United States Fish and Wildlife Service (USFWS) be included in the development and review of the Resources and Recreation Management Plan being prepared by the Irvine Ranch Conservancy for the Big Canyon Nature Park. This comment is noted; however, the development of the RRMP is not included as part of the CEQA document for the Big Canyon Restoration and Water Quality Improvement Project. Response to Comment B-2 This comment states that a detailed discussion concerning anticipated vegetation types in relationship to change in surface water flow, including whether or not the impacts of changed surface flow on vegetation types are significant without mitigation is provided. Surface diversion of water from east of Jamboree will capture approximately 5 percent of total surface water flow to be directed into the sanitary sewer. There are no anticipated hydrologic impacts associated with the diversion of this water to downstream habitat. In addition, in developing the floodplain restoration area, a hydraulic/hydrologic analysis was conducted to ensure that there is sufficient hydrology input to support the floodplain restoration area and existing vegetation. Response to Comment B-3 This comment provides a concern regarding the least Bell's vireo. No least Bell's Vireo have been documented in the immediate vicinity of the Big Canyon Restoration and Water Quality Improvement Project, either by ESA in 2015 or by Dudek in 2015. Clearing and grubbing activites will be conducted outside of the breeding season (February 15 - August 31); therefore, it is anticipated that there will be no habitat within the project limits to support least Bell's vireo by the time the birds arrive in March. However, adjacent downstream habitat could support this species, although none have been encountered in the Brazilian Peppertree forest on record. The incorporation of the mitigation measure to provide a 300 -foot minimum buffer for least Bell's vireo is considered an adequate avoidance measure. Response to Comment B-4 This comment request that protocol surveys for least Bell's vireo, along with any other reports and maps of significant impacts to native vegetation/foraging habitat be shared with CDFW. Results of the focused least Bell's surveys conducted by ESA and Dudek in 2015 were included in the Biological Technical Report (BTR) prepared for the project and is part of the CEQA document. The technical appendices were provided on a disk at the back of the paper copies of the MND and electronically included on the City's website. ESA's focused species report is included as an appendix to the BTR. The Inventory of Biological Resources Report prepared by Dudek (2015) is attached to this Response to Comments Letter as Attachment A-1 and is hereby incorporated as Appendix E.2 in Appendix C of the MND. The Response to Comments Letter, which will include Attachment A-1, will be available for CDFW to review. Additionally, the impact analysis is included in the MND, and has also been submitted as part of the application for a Streambed Alteration Agreement to the Department, which was submitted on January 25, 2016. Response to Comment B-5 This comment request that a daily monitor be present onsite should construction continue into the nesting season. The mitigation measures identified in BIO -1 for avoidance of nesting birds includes provisions for pre -construction nest surveys and implementation of nest buffers should a nesting bird be found within the project limits. These provisions are adequate to reduce potential significant impacts to less than significant impacts; however, to ensure that construction activities would result in potentially fewer impacts, the following is added to Mitigation Measure BI0-1. In addition, the number of days for nesting surveys prior to construction is revised to 3 as described in Response to Comment B-6. BIO -1: Nesting Birds. Impacts to nesting birds would be avoided by conducting all grading and construction activities outside of the bird breeding season (February 1 -August 15). If breeding season cannot be avoided, the following measures would be followed. a. During the avian breeding season, a qualified Project Biologist shall conduct a preconstruction avian nesting survey no more than 3470 days prior to vegetation disturbance or site clearing. If grading or other construction activity begins in the non - breeding season and proceeds continuously into the breeding season, no surveys shall be required. However, if there is a break of 33$ days or more in grading or construction activities during the breeding season, a new nesting bird survey shall be conducted before these activities begin again. b. The nest survey shall cover all reasonably potential nesting locations on and within 300 feet of the proposed construction activities areas. c. If an active nest is found during an avian nest survey, a qualified Project Biologist shall implement a 300 -foot minimum avoidance buffer for coastal California gnatcatcher, least Bell's vireo, and other passerine birds and a 500 -foot minimum avoidance buffer for all raptor species. Buffer distances for other species would be determined by the Project Biologist based on the species and its breeding or nesting requirements. The nest site area shall not be disturbed until the nest becomes inactive or the young have fledged. During clearing, grubbing, and excavation activities, the nest will be monitored by a qualified biologist for the duration of these activities, or until the nestlings have fledged. Daily monitoring may be required; however, the frequency of nest monitoring will be determined by the biologist based on the species and level of activity in the project area. Response to Comment B-6 This comment request that nesting surveys identified in Mitigation Measure BIO -1 be described as no later than three days prior to construction compared to ten days. The Applicant has concurred with this recommendation and Mitigation Measure BIO -1 as revised in Response to Comment B-5 above illustrates this revision. Response to Comment B-7 This comment states that CDFW will evaluate the adequacy of the proposed ratios at the time when the applicant formally submits a streambed notification package to the Lake and Streambed Alternation Program of CDFW. The Applicant acknowledges this comment and has submitted an application for a Lake and Streambed Alteration Agreement on January 25, 2016. The Applicant understands that the final mitigation ratios will be determined during that permitting process. Response to Comment B-8 This comment request additional information regarding how the provisions in Mitigation Measure BIO -3 will be implemented. The details requested in this comment will be included in the project Habitat Mitigation Monitoring Plan (HMMP) submitted for review and approval during the Lake and Streambed Alteration Agreement permitting process. Response to Comment B-9 This comment expressed a concern whether noise generated during project activities was considered as a potential significant impact to biological resources, particularly in regard to avian species. Based upon the anticipated project schedule provided in the MND which will conduct clearing and grubbing in the non -nesting season, coupled with the absence of sensitive avian species, the mitigation measures identified in Mitigation Measure BIO -1 for nesting birds will reduce potential noise impacts to avian species to less than significant. Typically mitigation measures pertaining to noise levels above 60 decibels address impacts to the bird's ability to communicate with a mate during the nesting season. Setbacks and measures have been identified in Mitigation Measure BIO -1 that address this comment. Response to Comment B-10 The commenter expressed a request to provide additional information regarding the potential impacts of the Polyphagous Shot Hole Borer (PSHB), which is an invasive beetle that carries three fungi, as a result of project activities. The PSHB is associated with riparian areas and known occurrence have include red willow and sycamore in the project vicinity. There are no reported incidences of the PSHB invading the Brazilian Peppertree. Based on a review of the current distribution of the PSHB from the University of California Agriculture and Natural Resources (http://ucanr.maps.arcgis.com/apps/Viewer/index.htmi?appid=3446e3llc5bd434eabae98937f085c80 ), the nearest occurrence of the PSHB is located approximately one mile east of the project site within Bonita Canyon Sports Park. This location does not appear to be associated with a riparian area. The next nearest location is east of Bonita Park, and this is a riparian area that drains north and is a tributary to San Diego Creek. This tributary does not extend into the project site. Therefore, there is a low probability that the PSHB would spread onto the project site since the project site does not contain PSHB and known occurrence of PSHB are not located in a tributary that conveys water onto the project site. However, out of an abundance of caution, Mitigation Measure BIO -2 has been revised as follows to address the construction and long-term maintenance activities on the project site. BIO -2: Vegetation Communities. The project would impact a total of 2.46 acres of southern riparian forest, and 0.50 acre of coastal sage scrub. These vegetation communities are both highly disturbed from a heavy infestation of non-native plants and compacted, saline soils. These low -quality habitats would be restored to provide habitats with much greater ecological function than the current conditions. A total of 2.46 acres of southern riparian forest would be mitigated onsite through substantial habitat restoration (2.03 acres), willow riparian forest habitat creation (0.25 acre), and riparian habitat enhancement (0.64 acre). Impacts to coastal sage scrub would be mitigated onsite through restoration of 1.85 acres, which is 1.35 acres in excess of the required 1:1 ratio. Impacts to non-native grassland, disturbed areas, and ornamental vegetation do not require mitigation (Table 3-5). TABLE 3-5 MITIGATION FOR IMPACTS TO VEGETATION COMMUNITIES Plant Communities and Land Cover Types Impacts (Acres)' Required Mitigation (1:1 ratio) Actual Mitigation (Acres) Excess (Acres) Southern Riparian Forest (SRF)' 2.46 2.46 2.923 +0.46 Coastal Sage Scrub (CSS) 0.50 0.50 1.85 +1.35 Non -Native Grassland (NNG) 1.20 0.00 0.00 0.00 Disturbed (Existing Roads & Trails) 0.13 0.00 0.00 0.00 Ornamental (ORN) 0.06 0.00 0.00 0.00 Total Acreage of Impacts 4.35 2.96 4.53 +1.81 Includes permanent impacts, temporary impacts associated with habitat restoration component, and temporary impacts associated with construction of water quality facilities and infrastructure. Note that some portions of the existing southern riparian forest habitat are not considered jurisdictional by the Corps/RWQB and/or CDFW; therefore, refer to Table 5 for detailed impact acreages of jurisdictional resources. Includes 2.03 acres of substantial restoration, 0.25 acre of habitat creation, and 0.64 acre of habitat enhancement. SOURCE: ESA, 2016 In addition, as part of the Habitat Restoration Plan, construction and operational Best Management Practices (BMPs) will be implemented to protect trees within the riparian habitat from the Polyphagous shot hole borer (PSHB). PSHB is a new insect pest in southern California that drills into trees and carries in a symbiotic fungus, which infests and kills the tree (UCR, Center for Invasive Research 2016). The nearest known infestation is 1 mile east of the project site. This invasive species is potentially devastating to native riparian habitat, as it can attack a variety of native tree species, such as Coast Live Oak (Quercus agrifolia), California sycamore (Platanus racemosa), Fremont cottonwood (Populus fremontii), red willow (Salix laevigata), and white alder (Alnus rhombifolia). PSHB attacks a variety of non-native species as well; however, there are no reported incidences of PSHB invading the Brazilian peppertree. In order to ensure that project activities do not result in the spread of PSHB into the project site, the following Best Management Practices will be employed: 1. During the tailgate training prior to construction, the onsite workers will be educated about PSHB and its spread; 2. Prior to Peppertree removal, the project area will be surveyed for signs of PSMH; if potential signs are observed, the University of California Cooperative Extension in Orange County (UCCE) and/or University of California, Riverside Eskalen Lab will be notified for confirmation (UCREL). 3. Should PSHB be found in any material that will be cleared and grubbed, the material shall be chipped to <1" and disposed of in an approved landfill. Other remediation actions will be discussed with UCCE or UCREL. 4. To reduce the spread of the beetle or fungus, all equipment will be disinfected prior to coming onsite. Response to Comment B-11 This comment expressed concerns regarding future restoration activities within Big Canyon. The future restoration activities referenced by the commenter refer to a project proposed in 2008 and previously reviewed by the California Department of Fish and Wildlife. This previous project was terminated and the activities associated with the previous project are not part of the proposed project. Any additional restoration efforts within Big Canyon that are no part of the proposed project would be required to undergo independent CEQA review.

The City acknowledges that the riparian habitat creation area discussed in the comment is the same as the 0.25 acre of willow forest, as depicted in Figure 5 in the MND. The Applicant has applied for a Section 401 Permit from the RWQCB. Response to Comment C-2 This comment states that the RWQCB may accept additional jurisdiction for State waters. In addition, this comment states that the proposed approximate 1:1 mitigation ratio appears acceptable, but approval of this ratio will ultimately depend upon the program and, construction specified in the CWA Section 401 Certification application. The habitat restoration area is a voluntary effort to improve habitat, and is a project component in which no compensatory mitigation is required. The removal of invasive species and the restoration of a non-functioning floodplain are not being implemented as a result of permanent impacts. Temporary impacts to degraded habitat will occur as a result of the restoration activities but do not trigger compensatory mitigation due to the nature of the restoration effort. To clarify, impacts to RWQCB jurisdiction will be mitigated for through the creation of like -kind habitat in the form of 0.25 acre of riparian habitat on a 1:1 basis. The Applicant has applied for a CWA Section 401 Certification and final mitigation requirements will be determined during that process. Response to Comment C-3 This comment asks if the Brazilian pepper tree consists of the virulently invasive Schinus terebinthifolius. The Applicant acknowledges the RWQCB's comment. Based upon field surveys by both ESA and Dudek biologist, Schinus terebinthifolius is the invasive species present on the project site. Response to Comment C-4 This comment expressed a concern regarding the proposed soil amendment following the invasive plant removal on the project site. The City has retained a soil scientist to assist in determining appropriate soil amendments that are appropriate for this soil condition. The Habitat Mitigation and Monitoring Plan (H MMP) that will be submitted for review and approval during the 401 Certification process will provide details on the proposed amendments. The amendments and methodologies are based upon established organic practices that regularly address salts and movement of nutrients in the soil profile. This comment also expressed a concern that the selenium that naturally occurs within marine deposits could affect the habitat restoration area. The marine deposits in question are upstream of the habitat restoration area, to the east of Jamboree and therefore the selenium that naturally occurs within this marine deposit will not affect the habitat restoration or mitigation areas. Based upon soil samples collected to date, selenium is not an issue in the habitat restoration or mitigation areas. Site grading will be limited and would not lower the existing ground levels to an extent that would create a situation where the roots of new plantings would access the groundwater. Also note that there has been fill placed throughout the canyon which may be the cause of high salt levels, and therefore, soil testing during restoration implementation will be prescribed to further fine tune soil amendments. Response to Comment C-5 This comment requested a stormwater sampling program associated with the bioretention cell treatment system. The City will be completing a Water Quality Monitoring Plan as part of the project and will provide the plan prior to permit approval by the Santa Ana Regional Water Quality Control Board. The Water Quality Monitoring Plan will include collecting storm flow samples at the inlet and outlet of the bioretention cell to assess the effectiveness of the system to remove the target pollutants from stormwater. Response to Comment C-6 This comment requested some form of protective structures for the sewer lines parallel to Jamboree Road to prevent future rupture. The City will maintain the required protective cover over the sanitary sewer lines which will be adequate to prevent future ruptures. Response to Comment C-7 This comment states that the Santa Ana Regional Water Quality Control Board staff supports the proposed project and states that the project would need to demonstrate protection of Newport Bay's beneficial uses. The City is partnering with the Newport Bay Conservancy and the California Department of Fish and Wildlife for a planning grant through the California Coastal Conservancy for potential future phases of the restoration project. We want to thank the Santa Ana Regional Water Quality Control Board for previous and current support on grant applications to provide the resources to continue these efforts to protect and restore the designated beneficial uses in Big Canyon and the Upper Newport Bay. Response to Comment C-8 This comment identified that the total maximum daily load (TMDL) for selenium is currently being developed, but has not been established. The first paragraph under Section 2.1.2.3 is revised to clarify the status of the TMDL for selenium as follows: During wet weather, roadway -related pollutants (e.g., metals, sediment, oil and grease) enter Big Canyon Creek from thoroughfares such as Jamboree Road and impact creek water quality. The project includes measures to reduce metals and sediment loading into the creek and Bay from stormwater flows from Jamboree Road. Big Canyon Creek is listed as an impaired waterbody for selenium_ and A total maximum daily load (TMDL) for selenium is under development that will address Big Canyon Creek and other freshwater tributaries in the Newport Bay watershed. The receiving water for Big Canyon Creek is Newport Bay, which is listed as an impaired waterbody for metals, toxics, nutrients, and bacteria. TMDLs have also been established to address these impairments. Response to Comment C-9 This comment noted that the reference to selenium guidelines should be referenced as water quality criteria for selenium. The second paragraph under Section 2.1.2.3 is revised to clarify the terminology regarding selenium criteria. Big Canyon Creek, which drains the Big Canyon Watershed, is one of the few perennial streams that discharge to Upper Newport Bay. Concentrations of selenium above applicable water quality criteria for selenium (California Toxics Rule chronic freshwater criteria) des have been measured in dry weather flows in Big Canyon Creek. The City has developed and is implementing a selenium reduction program in the watershed that includes dry weather diversions and other measures to reduce the selenium concentrations in the creek and into Upper Newport Bay. This project includes additional measures to substantially reduce selenium loading in dry weather flows as part of the selenium reduction program. Response to Comment C-10 This comment raised a concern of ponded water in the proposed stilling basin. The fifth bullet under Section 2.3, Infrastructure Improvements is revised to clarify the design of the stilling basin. • Infrastructure Improvements - The Project will also be constructed in coordination with infrastructure improvements by the Orange County Sanitation District (OCSD). The improvements are shown on Figure 3 and include the extension and improvement of the existing access road along the toe of slope along the west side of Jamboree Road. The access road improvements will be used access and maintain the sanitary sewer manhole located to the north of the existing culvert outfall. The construction of the access road to and over the existing culvert under Jamboree Road requires the extension of the culvert as shown on Figure 3. A concrete stilling pool will be located at the end of the culvert extension to dissipate hydraulic energy as the stormwater transitions from flow in the culvert and discharges to the regraded floodplain. This stilling pool will be periodically maintained to remove sediment and vegetation. Water from the stilling pool will exit via a rip rap energy dissipater. The stilling basin will be designed to address ponded water after storm events using orifice type outlets for low flows. Collection of dry weather seeps from the creek on the east side of Jamboree Road will be directed to the stilling basin and then directed to the OCSD sanitary sewer. The system will be designed to avoid ponding in the stilling basin for more than 72 hours, which will minimize the support of aquatic insects, fish or other aquatic organisms that might be attractive to birds. OCSD will also install a permanent dosing station and access area located to the south of the proposed habitat creation area. Response to Comment C-11 This comment requested a discussion of whether there are native plants adapted to the high salt levels within the soil. The HMMP being prepared forth e project addresses the need for soil amendments to tie up salts that will allow native plants to persist. Currently salt levels favor the Brazilian Peppertree, which has very high salt tolerance. Where there is freshwater input, along the active channel, the native riparian vegetation is present. The Monterrey Formation does not affect surface level soils. It is believed that some of the very high salt levels are a result of previous human - placed soil deposits from dredging activities. It is also noted that Tidal Flat soil occurs just downstream, so at some point the soils may have been influenced by saltwater input. That hydrologic condition is no longer present. Given that there is continuous freshwater input, the restoration area has been designed to capture those floodwaters. Naturally high salt levels will be flushed during flooding events, and soil amendment during the initial installation will allow those salts to be moved down the soil profile as well as adsorbed on organic matter surfaces. Response to Comment C-12 This comment raised concerns regarding the infiltrating groundwater and surface flow returns to the creek. The ninth paragraph in Section 2.4.2.1 is revised to clarify infiltration and surface flow. Stormwater will flow via gravity from the primary stormwater treatment structure to the top of the subcells through a series of perforated and solid inflow PVC pipes. Pollutants would be removed from stormwater as it flows down through the treatment media. Treated water would flow from the bottom of the bioretention cell through a series of PVC pipes into a newly created wetland habitat area located to the south of the bioretention cell (see Figure 5). The wetland habitat area will be graded to allow for infiltration to groundwater and for surface flow return to Big Canyon Creek. The groundwater level in the piezometer in the vicinity of the bio -retention cell is deeper than found at the other piezometers. Given the stratigraphy of the area, the Jamboree Road seeps are not a likely source to this area. Interactions between the deep groundwater and the biofiltration unit are not expected. Water quality monitoring of the bioretention cell and created wetlands are planned and is defined in the Water Quality Monitoring Plan that will be submitted prior to final permit approval. Response to Comment C-13 This comment refers to the description of the dry weather flow diversion. The third paragraph in Section 2.4.2.2 is revised to clarify the description as follows. Numerous studies and assessments on selenium loads and sources in Big Canyon Creek have been conducted. Reeder (2011) provided a comprehensive assessment of the geology, hydrology, and water quality related to selenium sources in the watershed from studies conducted as early as the 1970s through 2011. Since then, additional studies have been conducted in the watershed on flow rates (Weston 2013), water balance in the upper watershed (DBS&A 2015), and specific selenium source identification assessments in the lower portion of the watershed (City of Newport Beach, unpublished data). Based on long-term monitoring conducted in 2012 (Weston 2013), the approximate base dry weather flow rate of Big Canyon Creek at Jamboree Road is 0.420 cfs. The proposed dry weather flow diversion upstream of Jamboree Road is not anticipated to impact the natural creek function. It will divert lower selenium water around a stream reach of approximately 170 feetjust upstream of Jamboree Road (Figure 5) where higher selenium groundwater seeps have been identified (City of Newport Beach, unpublished data). Groundwater originating in this reach is estimated to contribute less than ten percent of the dry weather baseline flow in the creek, which will be diverted to sanitary sewer. The wet weather function of the creek will not be affected by the dry weather flow diversion. Response to Comment C-14 This comment requested that the stilling pool be reassessed so that the selenium seepage flows can bypass the stilling pool and be conveyed straight to the sewer. The sixth paragraph in Section 2.4.2.2 is revised to clarify the potential for reassessment. Seeps containing higher concentrations of selenium have been observed along the north and south banks along a 170 -foot reach of the creek on the east side of Jamboree Road near the existing culvert (City of Newport Beach, unpublished data). The seep flows will drain through the existing culvert and the new culvert extension and collect in a low point in the bottom the stilling basin floor. As the seep water collects and pools, it will then spill over into vertical open topped risers or similar system and drain into the OCSD sewer. The design will enable sediment to settle out and collect in the stilling basin floor while allowing the seep water to discharge to the sewer. The seep water diversion system will be designed such that the system can be shut off prior to precipitation events. The seep water diversion system will be designed such that the pooled water in the stilling basin floor is limited in extent to minimize mosquito vector habitat, and does not provide an attraction to birds or habitat for fish that would then be exposed to the higher selenium concentrations. Response to Comment C-15 This comment expressed a concern regarding selenium not accumulating in soils or plants if diverted water is used for irrigation. The fifth paragraph in Section 2.4.2.2 is revised as follows: The diversion line may be extended to the bio -infiltration cell (if slopes allow) to enable irrigation of native vegetation on the surface of the bioretention cell during the plant establishment period and for persistence of the vegetation. If this diverted water is used for irrigation, the potential for accumulation of selenium in the bioretention cell that would not otherwise be addressed through the basin's maintenance program will be assessed through the proposed water quality monitoring program that is described in the Water Quality Monitoring Plan to be provided prior to final permit approval. The project will install a potable line to provide an alternative source of water if that should be required. City of Newport Beach Planning Division, Patrick Alford, March 10, 2016. Response to Comment D-1 The City commented that Back Bay Drive is designated in the City Natural Resources Element as a Coastal View Road. The proposed project would include vehicles accessing Back Bay Drive during construction activities; and potential vehicles during periodic maintenance activities. These construction and operational activities would not result in a substantial impact on views from the Coastal View Road along Back Bay Drive due to the short-term and periodic nature of these activities. Response to Comment D-2 The City had a comment regarding the classification of an Environmental Sensitive Area (ESA) in Big Canyon as shown on Figure NR2 in the Natural Resources Element of the City of Newport Beach General Plan. The mouth of Big Canyon is classified as an ESA. While the project area is upstream of the mouth of Big Canyon, the project area does support species and habitats that are sensitive. While the project area has not been determined to be an Environmentally Sensitive Habitat Area (ESHA), the mitigation measures in the MND will provide adequate protection to prevent habitat disruption and will limit uses dependent upon those sensitive resources.

Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California Dear Dr. Pratt: This letter report documents the results of several biological resource surveys completed in 2015 for the Big Canyon Nature Park (BCNP) located in the City of Newport Beach, in Orange County, California. It also discusses the results of biological surveys conducted by other firms/organizations in 2015. These survey findings will inform management decisions made by the Irvine Ranch Conservancy (IRC) and support preparation of a Resource and Recreation Management Plan (RRMP) for the 50 -acre BCNP. This letter report is intended to: (1) describe the existing conditions of biological resources within the project site in terms of vegetation, flora, wildlife, and wildlife habitats; (2) provide a census and locational data for special -status biological resources observed within 2015; and (3) offer suggestions and recommendations for future restoration and management activities within BCNP. 1 INTRODUCTION 1.1 Project Location and Description The study area evaluated for biological resources included the 50 -acre BCNP, approximately 10 acres of the adjacent Upper Newport Bay Ecological Reserve, plus a 100 -foot buffer surrounding these open space areas for a total of approximately 88 acres (BCNP study area or study area; Figure 1). The study area is located approximately 2.5 miles north of the Pacific Ocean, in Sections 24 and 25 of Township 6 South, Range 10 West of the Newport Beach 7.5 minute U.S. Geological Survey (USGS) topographic quadrangle (Figure 2). This 88 -acre Big Canyon study area is situated between Upper Newport Bay (west of Back Bay Drive) and Jamboree Road within the central -western half of the City of Newport Beach. Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California The entire BCNP is mapped within the coastal zone and is bounded by urbanized areas, including single-family residences, roadways, and a golf course adjacent to the east portion of the BCNP open space area. The BCNP is designated as non -Reserve open space lands within the Central -Coastal Subregion Natural Community Conservation Plan/Habitat Conservation Plan (Central -Coastal NCCP/HCP). Although not part of the Reserve system, appropriate management of the natural resources within the BCNP is important. The results of biological resource surveys conducted in 2015 will aid in the preparation of the RRMP, which is a critical component of identifying, preserving, and protecting the unique resources of the BCNP while integrating passive and recreation uses, as appropriate. 1.2 Environmental Setting The 50 -acre BCNP is part of Upper Newport Bay (one of the largest remaining natural estuaries in Southern California). Upper Newport Bay encompasses approximately 1,000 acres of public open space comprised of three management areas: (1) the 752 -acre Upper Newport Bay Ecological Reserve (managed by the California Department of Fish and Wildlife); (2) the 140 -acre Upper Newport Bay Nature Preserve (managed by the Orange County Parks); and (3) the 50 -acre Big Canyon Nature Park (owned by the City of Newport Beach and managed by the IRC). Big Canyon is a natural canyon that is bounded by urbanized areas, including single-family residences, roadways, and the Big Canyon Golf Course. The Big Canyon Creek watershed encompasses approximately 1,200 acres (2 square miles) from its headwaters located near the San Joaquin Reservoir to the mouth of Big Canyon Creek where it discharges into Upper Newport Bay at its western extent. The lower reach of the Big Canyon watershed has been significantly altered over the decades. As early as the 1950s and 1960s, the lower reach of Big Canyon, which encompasses the BCNP, has been influenced by the construction of salt evaporation ponds, historical placement of dredge and fill material, interim restoration efforts, and other anthropogenic activities. Stockpiling of dredge fill during the 1950s and 1960s within Big Canyon Creek raised the elevations within the canyon and consequently channelized the creek to the north. 1.3 Topography/Hydrology The BCNP is characterized by a flat to moderately -sloping floodplain with steep northern and southern bluffs. Elevations within the BCNP ranges from below mean sea level at its western- most extent, where it intercepts with the Upper Newport Bay west of Back Bay Drive, to approximately 115 feet above mean sea level (AMSL) along the southern extent of the canyon. 8811-01 D U D E K 2 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California Although the central portion of the BCNP is relatively flat, the topography slopes moderately with slightly higher elevations occurring in the east (upstream) compared with the west (downstream). The eastern portion of the Big Canyon floodplain is approximately 50 feet AMSL, while the western portion of the Big Canyon floodplain is ranges between 15 and 20 feet AMSL east of Back Bay Drive. The BCNP has a combined maximum vertical relief of approximately 75 feet between the highest and lowest elevation points on the property. Slopes range in elevation from 20 to 75 feet AMSL, with Big Canyon Creek ranging from below mean sea level to 25 feet AMSL. Slopes within the BCNP vary by location. The central portion of the BCNP is relatively flat with slopes averaging approximately 7%, while the bluffs to the north and south of the property exceed 50%. The City of Newport Beach is located within the boundaries of four watersheds, including the Newport Bay, Newport Coast, Talbert, and San Diego Creek watersheds. These watersheds contain an interconnected system of surface water resources, which feed into the underlying groundwater aquifer or drain into the ocean (City of Newport Beach 2006). Big Canyon is one of the numerous drainages that contribute freshwater flows to the Newport Bay watershed. Big Canyon's contributing watershed encompasses approximately 1,300 acres (2 square miles) that is primarily characterized as developed. The majority of the watershed (approximately 96%) consists of residential, commercial, recreational (golf course, sports parks), cemetery, and other urban land covers. Previous hydrologic analyses have organized the watershed into three segments (Upper — headwaters to MacArthur Boulevard; Middle — MacArthur Boulevard to Jamboree Road; and Lower — Jamboree Road to Upper Newport Bay) of which Big Canyon Creek encompasses the lower segment of the watershed (WRC 2007). 1.4 Soils According to the USDA NRCS (2015), there are eleven soil types found in the project site: Anaheim clay loam, 15% to 30% slopes; Anaheim clay loam, 30% to 50% slopes; Balcom clay loam, 30% to 50% slopes; beaches; Calleguas clay loam, 50% to 70% slopes, eroded; Cieneba sandy loam, 30% to 75% slopes, eroded; Marina loamy sand, 2% to 9% slopes; Myford sandy loam, thick surface, 2% to 9% slopes; San Emigdio fine sandy loam, moderately fine substratum, 0% to 2% slopes; Sorrento loam, 2% to 9% slopes; and tidal flats. A brief description of these soil series are provided below according to Wachtell (1978) and NRCS (2015). Although beaches and tidal flats do not belong to a soil series, these miscellaneous areas are also described below. Anaheim Series soils are formed in material weathered from fine-grained sandstone or shale. This soil is well -drained on moderately steep to very steep foothills. The soils 8811-01 D U D E K 3 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California identified within the study area have a loam texture. Runoff is rapid to very rapid with moderate to moderately slow permeability. Balcom Series soils are formed in material weathered from soft, calcareous shale and fine-grained sandstone. This soil consists of moderately deep, well -drained soils with an effective rooting depth of 24 to 30 inches. The Balcom soil profile consists of loam, silt loam, clay loam, or silty clay loam with more than 15% fine sand or coarser. This soil is well -drained with low to high runoff and moderate to moderately slow permeability. Beaches support little to no vegetation and consist of sandy, gravelly, or cobbly coastal shores washed and rewashed by tidal and wave action. These areas have very slow runoff and high erosion hazard, and may be partly covered with water during high tide or stormy periods. Calleguas Series soils are formed in material weathered from sedimentary rocks (i.e., sandstone, shale, and mudstone) on uplands, hills and mountains. Calleguas soils are very shallow and typically on exposed and eroded south -facing slopes. This soil is well - drained with medium or high runoff and moderate permeability. Textures vary between loams and silty clay loams. Cieneba Series soils are formed in material weathered from granitic rock and typically very shallow, ranging between 4 and 20 inches in depth This series includes somewhat excessively -drained soils with low to high runoff. Permeability is moderately rapid in the soil and much slower in weathered bedrock. Soil textures consist of coarse sandy loam, sandy loam, or loam with a gravelly modifier. Marina Series soils are formed in old eolian sands near the coast. Marina soils occur on rolling dune -like, gently sloping to moderately steep slopes and terraces. This soil series is somewhat excessively -drained with slow to rapid runoff and moderate permeability. Soil depths range between 12 and 35 inches, with an effective rooting depth of 60 inches or more, and sand to loamy fine sand texture. Myford Series soils are formed in sandy sediments on nearly level to moderately steep marine terraces. Myford soils are deep, moderately well -drained soils with medium to rapid runoff and very slow permeability. Soil textures range between sandy loam and sandy clay loam. San Emigdio Series soils are primarily formed in sedimentary alluvium. This soil is very deep and well -drained. It commonly occurs on alluvial fans, floodplains, and in narrow valleys. Runoff is negligible to low with moderately rapid permeability. Soil texture is coarse sandy loam, sandy loam, fine sandy loam, silt loam, or loam to a depth of 40 inches with rock fragments greater within the lower portion of the profile. 8811-01 D U D E K 4 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California Sorrento Series soils are formed in extremely textured alluvium primarily from sedimentary rocks. Sorrento soils are very deep, well -drained soils on alluvial fans and stabilized floodplain. Runoff is negligible to medium with moderate to moderately slow permeability depending on the dominant texture and stratification in the lower portion of the profile. Tidal Flats are stratified clayey to sandy deposits found on nearly level areas adjacent to bays and lagoons along the coast. These areas can periodically be covered by tidal overflow, with some of the higher areas only covered during very high tides. Runoff generally ponds, thus tidal flats are poorly drained and high in salts. 2 METHODS Data regarding biological resources present within the study area were obtained through a review of pertinent literature review, field reconnaissance, and focused surveys, which are described in detail below. All biological resources detected within the survey area were mapped utilizing a Global Positioning System (GPS) handheld unit with sub -meter accuracy (Trimble GeoXT). Biologists also utilized a 100 -scale (1 inch = 100 feet) field map with the survey area and project site on an aerial map. 2.1 Literature Review Prior to conducting the field investigations, a review of the existing biological resources and species within the vicinity of the survey area was conducted using the California Department of Fish and Wildlife (CDFW; formerly California Department of Fish and Game) California Natural Diversity Database (CNDDB) (CDFW 2015), the California Native Plant Society (CNPS) Inventory of Rare and Endangered Plants (CNPS 2013), and U.S. Fish and Wildlife Service (USFWS) data (USFWS 2013). CNDDB and CNPS were queried based on the Newport Beach USGS topographic quadrangles within which the survey area is located and the surrounding six USGS quadrangles, including the Anaheim, Orange, Seal Beach, Los Alamitos, Tustin, Laguna Beach USGS quadrangles. Other literature reviewed included Big Canyon Creek Historic Tidal Wetlands Conceptual Restoration Plan, Upper Newport Bay (CCI 2004) and Big Canyon Creek Restoration Project Phase II Feasibility Study (WRC 2007). The purpose of this review was to determine if special -status plant species and wildlife species are known to occur within or in the nearby vicinity of the survey area. 2.2 Field Surveys Dudek conducted several field surveys within the 88 -acre study area including vegetation community and land cover mapping, invasive tree surveys, aquatic invasive species surveys, and 8811-01 D U D E K 5 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California raptor nest surveys between February and July 2015. Additionally, focused plant and wildlife surveys were conducted. Dudek conducted focused, protocol -level surveys for burrowing owl (Athene cunicularia), least Bell's vireo (Vireo Belli pusillus), southwestern willow flycatcher (Empidonax traillii extimus), and coastal California gnatcatcher (Polioptila californica californica). Focused special -status plant surveys were conducted by Fred M. Roberts, Jr. within BCNP (Roberts 2015). Table 1 lists the dates, conditions, and focus for each survey. Descriptions of the methods used for each survey are provided below.

Roberts, Jr. 2.2.1 Vegetation Community and Land Cover Mapping Vegetation communities and land uses within the study area were mapped in the field directly onto a 100 -foot -scale (1 inch = 100 feet), aerial photograph -based field map of the BCNP study area. Following completion of the fieldwork, all vegetation polygons were digitized using ArcGIS and geographic information system (GIS) coverage was created. Once in ArcGIS, the acreage of each vegetation community and land cover present on site was determined. 8811-01 D U D E K 7 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California Vegetation communities were mapped using CDFW's Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Natural Communities (CDFG 2009) and List of Vegetation Alliances and Associations, also referred to as the Natural Communities List (CDFG 2010). The vegetation communities are similar to those in the Central -Coastal NCCP/HCP EIR/EIS database, which is based on the Orange County Habitat Classification System (Jones and Stokes, 1993; Gray and Bramlet 1992). Additionally, Dudek reviewed and incorporated vegetation community classifications for BCNP provided by the Nature Reserve of Orange County (NROC 2015). Adjustments were made to rectify polygon shapes and sizes, and the naming convention based on the more recent classification standard developed by the CDFW. 2.2.2 Plants All plant species encountered during the vegetation mapping efforts conducted by Dudek on February 18, 2015 were identified and recorded in a field notebook. Those species that could not be identified immediately were brought into the laboratory for further investigation. Latin and common names for plant species with a California Rare Plant Rank (CRPR) (formerly CNPS List) follow the Inventory of Rare and Endangered Plants (CLAPS 2013). For plant species without a CRPR, Latin names follow the Jepson Interchange List of Currently Accepted Names of Native and Naturalized Plants of California (Jepson Flora Project 2012), and common names follow the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (MRCS) Plants Database (USDA 2012). Roberts (2015) conducted focused special -status plant surveys within BCNP between April 16, and July 1, 2015, which are also incorporated in this report and discussed in detail below. Appendix A contains a complete list of plant species observed during Dudek and Roberts (2015) surveys conducted in 2015. 2.2.3 Wildlife All wildlife species detected during the field surveys by sight, calls, tracks, scat, or other signs, were identified and recorded in a field notebook. Binoculars (10X40 magnifications) were used to aid in the identification of observed wildlife. In addition to species actually detected, expected wildlife use of the site was determined by known habitat preferences of local species and knowledge of their relative distributions in the area. Dudek conducted focused surveys for burrowing owl, least Bell's vireo, southwestern willow flycatcher, and coastal California gnatcatcher, discussed in detail below. Additional data 8811-09 Q U Q E K 8 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California regarding wildlife occurrence on the site was provided through focused surveys for salt -marsh dependent species conducted by Zembal in early March 2015, also discussed in detail below. Latin and common names for vertebrate species referred to in this report follow Crother (2014) for amphibians and reptiles, American Ornithologists' Union (AOU) Check -List of North American Birds (AOU 2015) for birds, Wilson and Reeder (2005) for mammals, and North American Butterfly Association (NABA 2001) for butterflies. Appendix B contains a complete list of wildlife species observed during the surveys. Raptor Nests Qualified Dudek biologists conducted a nesting bird survey focused on habitats potentially utilized by raptor species. The survey was conducted on foot throughout the study area, which included an appropriate buffer (100 foot minimum). All suitable nesting bird habitat was thoroughly surveyed to identify potential nesting behavior (i.e., territorial defense, transport of nesting material or food for young, etc.) and the locations of active nests. Dudek recorded all bird species identified on the site during the survey. 2.2.4 Invasive Species 2.2.4.1 Exotic Trees Dudek mapped and collected tree attribute information for all invasive, exotic trees within the BCNP. The location of each individual tree was mapped using a Trimble Pathfinder GEO XT Global Positioning System (GPS) receiver. The Pathfinder has a horizontal accuracy of 1 -meter (1 -sigma) using differential code positioning techniques. Concurrent with tree mapping efforts, Dudek arborists collected tree attribute data including species, quantity of individual trunks, individual trunk diameters, overall height, and canopy extent. Diameter measurements were collected using the standard protocol outlined in the Guide for Plant Appraisal (Council of Tree and Landscape Appraisers 2000). Trunk diameter measurements were taken at 4.5 feet (54 inches) above the ground along the trunk axis, with a few common exceptions. In cases where a tree's trunk is located on a slope, the 4.5 -foot distance was approximated as the average of the shortest and longest sides of the trunk (i.e., the uphill side and downhill side of a tree's trunk, respectively) and the measurement was made at the circumference of the trunk at this point. Tree height measurements were ocular estimates made by experienced field arborists. Tree canopy diameters were typically estimated by "pacing -off' the measurement based on the investigator's knowledge of his stride length or by visually 8811-09 D U Q E K 9 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California estimating the canopy width. The tree crown diameter measurements were made along an imaginary line intersecting the tree trunk that best approximated the average canopy diameter. Upon completion of field data collection and mapping, raw GPS data was post -processed using GPS Pathfinder Office (v 3.10) and individual tree location data was compiled and updated in a GIS. The digital tree locations were linked to individual tree identification numbers and associated tree attribute data. 2.2.4.2 Invasive Aquatic Wildlife Surveys for aquatic invasive species were conducted within the BCNP by Dudek on April 29, 2015 and June 24, 2015. The surveys were focused on two species known to occur within BCNP: African clawed frog and red swamp crayfish. Another invasive aquatic species included in the assessment was the American bullfrog. Dudek conducted two trapping events for aquatic species at three locations within the BCNP using Promar minnow/crawfish steel traps (model number TR -601) baited with mackerel. These traps generally allow for the safe removal or escape of non -target species, including fish and amphibians, while still collecting the Focal Species. Traps were set within the upper reach (couple hundred feet downstream of the Jamboree culvert), middle reach, and lower reach (near maintenance road crossing of Big Canyon Creek) in the afternoon/dusk and checked early the following morning. During both afternoon/dusk and early morning visits, as well as during other focused wildlife surveys, the project area was visually searched for invasive aquatic wildlife. 2.3 Focused Surveys for Listed Species Dudek conducted focused surveys for special -status plant and wildlife species that were evaluated as having a moderate to high potential for occurrence within the study area. Species listed as either Covered, Conditionally Covered, or Non -Covered under the Central -Coastal Subregion NCCP/HCP, known to occur within a 5 -mile radius of the project site (CDFW 2015), or that have the potential to occur based on vegetation communities present on site were included in the surveys. 2.3.1 Special -Status Plants Focused special -status plant surveys were conducted by Fred Roberts throughout the study area between April 16, and July 1, 2015 (Roberts 2015; Appendix C). These surveys were conducted using wandering transects with special attention paid to areas that represented primary habitat. Observed plant species were recorded in the field and special -status plant locations were colleted 8811-09 Q U D E K 10 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California with a Garmin Map60CSX hand held GPS unit. Given the steep terrain associated with Big Canyon, some plant sites were sketched by hand and translated into digital polygons using Google Earth. Special -status species were recorded on standardized data forms. Appendix A contains a complete list of plant species observed during 2015 surveys. 2.3.2 Burrowing Owl Focused surveys for burrowing owl (CDFW Species of Special Concern) were conducted by Dudek Biologists Karen Mullen, Johanna Page, Ryan Henry, Jeffrey Priest, and Paul Lemons from March to July 2015 to evaluate the site conditions, habitat suitability, and presence/absence of burrowing owl. The weather conditions, time of day, and season were appropriate for the detection of burrowing owl (Table 1). The survey consisted of slowing walking methodical, meandering routes to provide 100% coverage of areas that provide suitable habitat for burrowing owl within the BCNP study area. During the survey, 100 -foot -scale (1 inch = 100 feet) aerial photograph -based field maps were used to record any areas potentially suitable for burrowing owl, and to map locations of observed burrowing owls, if detected. Any burrows detected during the survey were thoroughly examined for status (i.e., active or non-active) and burrowing owl sign (i.e., owl pellets, prints, molting feathers, abundant insect remains, etc.). All burrows greater than 11 centimeters (approximately 4 inches) in diameter (height and width) and greater than 150 centimeters (approximately 59 inches) in depth were documented as suitable burrows for burrowing owl as per the 2012 Staff Report on Burrowing Owl Mitigation (CDFG 2012). Binoculars (10x40 magnifications) were used to aid in detecting and identifying wildlife species. 2.3.3 Coastal California Gnatcatcher Focused surveys for the coastal California gnatcatcher were performed by Dudek Biologists Jeffrey D. Priest, Paul M. Lemons, Karen M. Mullen, and Johanna C. Page in April and May 2015. Mr. Lemons holds federal permit TE -051248-5 and Mr. Priest holds federal permit TE - 840619 -5.1 to conduct surveys for the coastal California gnatcatcher. All surveys conducted by Ms. Mullen and Ms. Page were conducted under the supervision of a permitted biologist. The surveys were conducted in accordance with the currently accepted protocol of the U.S. Fish and Wildlife Service's Coastal California Gnatcatcher (Polioptila californica californica) Presence/Absence Survey Protocol (USFWS 1997). Since the Project is located within the Central -Coastal NCCP/HCP plan area, the survey included three visits at a minimum of 7 -day intervals. Survey routes completely covered all areas of suitable coastal California gnatcatcher habitat on site. Appropriate birding binoculars were used to aid in detecting and identifying bird species. The survey conditions were within protocol limits, as shown in Table 1. The biologist �/ 8811-09 d U Q E K 11 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California played a tape of recorded vocalizations approximately every 50 to 100 feet to elicit a response from any California gnatcatcher present on site. All wildlife species detected during surveys were recorded. The full survey report is provided in Appendix D (Dudek 2015a). 2.3.4 Riparian Birds Focused riparian bird surveys were conducted for four special -status riparian bird species: the federally listed endangered southwestern willow flycatcher; the federally listed endangered least Bell's vireo; and the CDFW Species of Special Concern (SSC) yellow -breasted chat (Icteria vixens) and yellow warbler (Setophaga petechia). The focused riparian bird surveys were conducted by Dudek Biologists Paul Lemons, Jeffrey Priest, Karen Mullen and Johanna Page from April to July 2015. Mr. Lemons holds federal permit TE -051248-5 and Mr. Priest holds federal permit TE -840619-5.1 to conduct surveys for the southwestern willow flycatcher. All surveys conducted by Ms. Mullen and Ms. Page were either focused on the detection of least Bell's vireo, yellow -breasted chat or yellow warbler, for which a federal recovery permit is not required, and/or were conducted under the supervision of a permitted biologist, in the case of southern willow flycatcher surveys. Surveys were conducted concurrently for these four special - status riparian bird species whenever feasible. Appendices E contains the full report for the least Bell's vireo/willow flycatcher survey effort (Dudek 2015b). The Dudek survey effort was performed in conformance with current USFWS protocols and permit survey guidelines and requirements for the least Bell's vireo and southwestern willow flycatcher. Since not State or federally listed, there is no established protocol for yellow breasted chat and yellow warbler. Thus, yellow breasted chat and yellow warbler surveys were conducted consistent with the timing and methodology of least Bell's vireo and southwestern willow flycatcher. For least Bell's vireo, eight site visits were conducted with 10 -day intervals between each visit and all surveys were conducted between April 20 and July 15, which is within the April 10 to July 31 time frame specified in the protocol. For the southwestern willow flycatcher, five surveys are required per the protocol, with one visit between May 15 and May 31, one visit between June 1 and June 21, and three visits between June 22 and July 17. A total of five survey visits were conducted for the flycatcher. Each survey during the final period was separated by at least 5 days. Because the habitat requirements for the four special -status riparian bird species overlap, most of these surveys were conducted concurrently. 2.4 Survey Limitations Limitations of the surveys include a diurnal bias and the absence of trapping for small mammals, reptiles, and amphibians. Surveys were conducted during the daytime to maximize the detection 8811-09 Q U Q E K 12 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California of most animals. Birds represent the largest component of the vertebrate fauna, and because most birds are active in the daytime, diurnal surveys maximize the number of observations of birds. Conversely, diurnal surveys usually result in few observations of mammals, many of which may be active only at night. In addition, many species of reptiles and amphibians are secretive in their habits and are difficult to observe using standard meandering transects. The surveys were conducted during the spring and summer season, resulting in detection and identification of most annual and perennial plant species that occur in the area, as well as for observations of most neotropical migrant birds. However, the timing of the surveys may not have detected wintering birds within the study area. Numerous surveys have been conducted within the BCNP study area; therefore, there is a good understanding of which species have potential to occur within the study area during all seasons. Survey conditions were suitable/appropriate to allow for detection of the flora or fauna that were the focus of each survey effort. 3 RESULTS 3.1 Vegetation Communities A total of 20 vegetation communities and 8 land covers were identified within the study area. Descriptions of the vegetation communities and land covers are organized into three life forms (forest and woodland, shrubland, and herbaceous), referred to as formation classes, as recognized by the CDFW (CDFG 2010) and a fourth category (non -natural land covers/unvegetated communities). These categories are further organized by formation. Within each formation, the alliances and associations are organized alphabetically followed by mapping units. Unless noted otherwise, the vegetation alliance and associations are included in the Natural Communities List (CDFG 2010). These vegetation communities and land cover types are described as follows; their acreages are presented in Table 2; and their spatial distributions are presented on Figure 3.

Stands of California brittle bush shrubland form an intermittent to continuous shrub layer that is less than 6 feet (2 meters) with variable herbaceous layer (Sawyer et al. 2009). One mapping unit and one association within this alliance were mapped within the study area and are described below. The California brittle bush scrub alliance has a rank of G4S3, meaning it is apparently secure globally and is vulnerable to extirpation or extinction in the state. This alliance is considered a special -status vegetation community per CDFW (2010). This alliance is also considered a covered habitat within the Central -Coastal NCCP/HCP. California Brittle Bush -California Sagebrush Association The California brittle bush -California sagebrush association (Encelia californica—Artemisia californica association) typically includes California brittle bush as the dominant shrub with California sagebrush consistently present as a co -dominant or sub -dominant shrub. 8811-09 Q U Q E K 15 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California California Brittle Bush Disturbed Mapping Unit The California brittle bush disturbance mapping unit is not recognized by the Natural Communities List (CDFG 2010).

The disturbed or barren mapping unit, also identified by Gray and Bramlet as cleared or graded, refers to areas that lack vegetation but still retain a pervious surface, or that are dominated by a sparse cover of ruderal vegetation such as Maltese star -thistle, wild oat, black mustard, spiny sowthistle (Sonchus aspen), and prickly lettuce (Lactuca serriola). Ornamental Landscaping Mgpping Unit The ornamental landscaping mapping unit is not recognized by the Natural Communities List (CDFG 2010) but is described by Jones & Stokes (1993). This land cover type, also identified by Gray and Bramlet (1992) as parks and ornamental plantings, consists of introduced plantings of exotic, and sometimes native, species as landscaping that are actively maintained. Other Developed Areas Mapping Unit The other developed areas mapping unit is not recognized by the Natural Communities List (CDFG 2010) but is described by Jones & Stokes (1993). The other developed areas mapping unit, also identified by Gray and Bramlet (1992) as other developed areas, describes areas occupied by structures, paving, and other impermeable surfaces that typically do not support vegetation or habitat for species. Transportation Mapping Unit The transportation mapping unit is not recognized by the Natural Communities List (CDFG 2010) but is described by Jones & Stokes (1993) and Gray and Bramlet (1992). This barren cover type consists of major paved vehicular access roads that lack vegetation. Urban and Commercial Mapping Unit The urban and commercial mapping unit is not recognized by the Natural Communities List (CDFG 2010) but is described by Jones & Stokes (1993). The urban and commercial mapping unit, also identified by Gray and Bramlet (1992) as urban, describes areas occupied by residential and commercial structures, paving, and other impermeable surfaces that typically do not support 8811-09 Q U Q E K 22 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California vegetation or habitat for species; however, non-native ornamental landscaping may occur within the mapping unit. Water Open Water Mapping Unit The open water mapping unit is not recognized by the Natural Communities List (CDFG 2010) but is described by Jones & Stokes (1993). Open water consists of standing water with no emergent vegetation. Open water is not considered a riparian habitat because it lacks hydrophytic vegetation. Open water can be regulated by CDFW, pursuant to Section 1602 of the California Fish and Game Code, and the U.S. Army Corps of Engineers, pursuant to Section 404 of the federal Clean Water Act (33 U.S.C. 1251 et seq.). Intertidal Flat Intertidal Mudflat Mapping Unit The intertidal mudflat mapping unit is not recognized by the Natural Communities List (CDFG 2010), but is described by Jones & Stokes (1993). Intertidal mudflats consist of periodically exposed areas of estuarine silts, clays, and marine wildlife detritus. These areas are submerged and exposed approximately twice daily and generally do not support vascular plants. Salt Panne Mapping Unit The salt panne mapping unit is not recognized by the Natural Communities List (CDFG 2010). Salt pannes consist of historically inundated depressional areas within estuarine systems that have dried to form exposed, hyperaline soils with a salt crust surface. These unique microhabitats may support various species of halophytes and benthic plants along the higher elevation perimeter of the depressional area. 3.2 Plants Detailed biological studies to document the floral diversity within the BCNP have been conducted since 2003 in order to evaluate restoration opportunities. Additional focused botanical surveys were conducted in June and July 2015 (Roberts 2015). A total of 194 plant taxa were observed within BCNP during the 2015 surveys: 87 (45%) native species and 107 (55%) non- native species. The higher percent of non-native species is due to the historic disturbances within the canyon, proximity to urban/developed areas, and year-round water sources. Plant species 8811-09 D U D E K 23 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California richness is relatively high due to the variety of plant communities within the BCNP rather than a high diversity within a particular community. Few annual plant species were detected in the riparian forest and coastal scrub, for example because of the generally dense shrub cover. A complete list of vascular plants observed within the BCNP is included as Appendix A. Figure 4 illustrates the distribution of special -status plant species within the BCNP. 3.3 Wildlife A total of 73 wildlife species were recorded in the study area during general and focused 2015 surveys (Appendix B), including coastal or oceanic species, and some urban -adapted species. Most of the species observed within the study area were bird species, primarily due to the numerous focused bird surveys and diurnal nature of the surveys conducted within the study area. Overall, the diversity of wildlife species in the project site was high relative to the size of the project site due to the high quality riparian and wetland habitats, as well as the coastal sage scrub habitats. Birds Fifty-six avian species were observed in the study area during surveys conducted in 2015 (Appendix B). Common bird species observed within the study area include Anna's hummingbird (Calypte anna), Allen's hummingbird (Selasphorus sasin), western gull (Larus occidentalis), mallard (Anas platyrhynchos), common yellowthroat (Geothlypis trichas), bushtit (Psaltriparus minimus), mourning dove (Zenaida macroura), house finch (Carpodacus mexicanus), song sparrow (Melospiza melodia) and California towhee (Melozone crissalis). Special -status wildlife species observed within the study area are described below. Figure 4 illustrates the distribution of special -status bird species within the BCNP. Nesting Raptors No raptor nests were observed during the raptor nest surveys conducted on March 12, 2015 or during any other field survey conducted in 2015. Three raptor species were observed within the study area during biological field surveys: red -shouldered hawk (Buteo lineatus), white-tailed kite (Elanus leucurus); and osprey (Pandion haliaetus). The red -shouldered hawk is a Central -Coastal NCCP/HCP covered species, white-tailed kite is considered fully protected by CDFW (FP), and osprey is a CDFW Watch List species (WL). Other raptors that have been previous observed within the study area include: sharp -shinned hawk (Accipiter striatus; WL and Central -Coastal NCCP/HCP covered species), red-tailed hawk (Buteo jamaicensis), and northern harrier (Circus cyaneus; CDFW Species of Special Concern (SSC) and Central -Coastal NCCP/HCP covered species). Although no raptor nests were observed during 2015 surveys, potential nesting and foraging habitat is present 8811-09 Q U Q E K 24 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California within the study area. Thus, there is a high potential for raptors to nest within the BCNP study area. The study area contains many trees and vegetation within the coastal scrub and riparian habitat that could potentially be used by other migratory birds for breeding. Reptiles and Amphibians Four reptiles or amphibians were detected in the study area during the biological resource surveys, including: western fence lizard (Sceloporus occidentalis), common side -blotch lizard (Uta stanburiana), the non-native African clawed frog (Xenopus laevis), and the non-native American bullfrog (Lithobates catesbeianus). Common species that could occur based on resources present include southern alligator lizard (Elgaria multicarinata), gophersnake (Pituophis catenifer), California kingsnake (Lampropeltis califormae), and Baja California treefrog (Pseudacris hypochondriaca). Aquatic invasive species observed within the study area are described in Section 4.5 below. Mammals Six mammals were recorded in the study area during biological surveys. California ground squirrel (Spermophilus beecheyi) was the only mammal species observed during field surveys. Sign and/or tracks were observed for the following five mammal species: coyote (Canis latrans), brush rabbit (Sylvilagus bachmani), Botta's pocket gopher (Thomomys bottae), raccoon (Procyon lotor), and woodrat (Neotoma sp.; midden). Other common mammal species that have a potential to occur based on habitats present include Virginia opossum (Didelphis virginiana) and bobcat (Lynx rufus). Invertebrates Seven invertebrate species, including one aquatic invertebrate species, were detected during biological resource surveys: checkered white (Pontia protodice), mourning cloak (Nymphalis antiopa), cabbage white (Pieris rapae), western tiger swallowtail (Papilio rutulus), Lorquin's admiral (Limenitis lorquini), monarch (Danaus plexippus; California Special Animal List (SA)), and the non-native red swamp crayfish (Procambarus clarkii). Common species that have a potential to occur based on their known distribution throughout the BCNP include Behr's metalmark (Apodemia mormo virgulti), anise swallowtail (Papilio zelicaon), Pacific Sara orangetip (Anthocharis Sara), Acmon blue (Plebejus acmon), west coast lady (Vanessa annabella), painted lady (Vanessa cardui), buckeye (Junonia coenia) and California dogface (Colias eurydice). The also provides suitable habitat for other insect species including many species of Coleoptera (beetles), Hymenoptera (bees, ants and wasps), and Diptera (flies). 8811-09 Q U Q E K 25 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California 3.4 Invasive Species 3.4.1 Exotic Trees The primary exotic tree of concern was Brazilian peppertree, which was by far the most common invasive tree found. Other secondary exotics that were surveyed included eucalyptus (Eucalyptus camaldulensis, Eucalyptus polyanthemos, and Eucalyptus sideroxylon), ficus (Ficus spp.), Shamel ash (Fraxinus uhdei), Chinese flame tree (Koelreuteria bipinnata), goldenrain tree (Koelreuteria paniculata), ngaio tree (Myoporum laetum), Canary Island date palm (Phoenix canariensis), and Washington fan palm (Washingtonia robusta). Figure 5 illustrates the distribution of invasive tree species within the BCNP. 3.4.2 Invasive Aquatic Wildlife On April 29, four African clawed frogs (Xenopus laevis) and two red swamp crayfish (Procambarus clarkii) were collected within the upper reach of Big Canyon Creek just downstream of the Jamboree Road culvert (Trap 1). The two other traps set within Big Canyon Creek (Traps 2 and 3) were stolen from the project site and therefore no other results were obtained during the April trapping effort. On June 26, one African clawed frog was collected again within the upper reach of Big Canyon Creek at Trap 1 and three African clawed frogs were collected downstream within the middle reach at Trap 2. Red swamp crayfish were a common siting within the shallow surface waters of Big Canyon Creek during evening and morning visits. This species is assumed to occur throughout the length of Big Canyon Creek. Although African clawed frogs were not easily observed within or along Big Canyon Creek, they are also assumed to occur, and in higher population numbers, throughout the length of Big Canyon Creek. One other invasive aquatic species that was detected within the BCNP is the American bullfrog (Lithobates catesbeianus). One adult of this species was observed on June 21 within the lower reach of Big Canyon Creek at the trail that parallels Back Bay Drive. This species is assumed to occur within the open water/freshwater marsh vegetation communities, as well as throughout Big Canyon Creek. Figure 5 illustrates the distribution of invasive wildlife species within the BCNP. 8811-09 Q U Q E K 26 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California 3.5 Focused Surveys for Listed Species 3.5.1 Special -Status Plant Species No special -status plant species were identified within the study area during the vegetation mapping conducted on February 18, 2015. Four special -status plant species were observed within the BCNP study area during focused special -status plant species conducted by Roberts in 2015 (Appendix C): southern tarplant (Centromadia parryi subsp. australis; CRPR 113.1); southwestern spiny rush (Juncus acutus ssp. Leopoldii; CRPR 4.2); California boxthorn (Lycium californicum; CRPR 4.2); and woolly seablite (Suaeda taxifolia; CRPR 4.2). Figure 4 illustrates the distribution of special -status plant species within the BCNP. Other special -status plant species documented in the literature review and identified within the study area during previous surveys include: salt marsh bird's beak (Chloropyron maritimum ssp. Maritimum; federally endangered (FE), CDFW candidate for endangered (CE), CRPR 113.2), and estuary seablite (Suaeda esteroa; CRPR 113.2). 3.5.2 Burrowing Owl No burrowing owl individuals or potential sign was detected during the 2015 focused burrowing owl surveys. Very few burrows and/or burrow surrogates of appropriate size were observed during the habitat assessment and/or subsequent surveys. A few California ground squirrel burrows were observed within the survey area. However, nearly all of the burrows detected were determined to be inactive due to being partially backfilled with debris and/or presence of spider webs or based on the lack of burrowing owl sign or individuals. Additionally, there is a low potential for the BCNP study area to support burrowing owls due to the lack of adjacent suitable foraging habitat. 3.5.3 Coastal California Gnatcatcher Coastal California gnatcatchers are federally -listed as threatened, state -listed as a Species of Special Concern, and considered a "Covered Species" in the Central -Coastal NCCP/HCP. One pair of coastal California gnatcatchers and potentially one separate individual coastal California gnatcatcher was observed within the study area by Dudek during 2015 focused surveys (Dudek 2015a; Appendix D). All detections of coastal California gnatcatcher were identified within the coastal scrub habitat located in the southwestern portion of the study area. The pair of coastal California gnatcatchers was observed within a fenced area dominated by coastal scrub habitat located along the coastal bluff, approximately 100 feet west of the residential development. A single coastal California gnatcatcher individual was identified in six locations within coastal scrub habitat within the BCNP during separate survey efforts. It is difficult to determine whether 8811-09 Q U Q E K 27 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California this individual was the same individual identified as a pair or whether there are one or numerous individuals within the study area. The California gnatcatcher use area, which includes the distribution of individual observations, is depicted in Figure 4. 3.5.4 Riparian Birds No least Bell's vireo or southwestern willow flycatcher were observed within the study area during the 2015 focused riparian bird surveys (Dudek 2015b; Appendix E). Yellow -breasted chat were observed in two locations within the riparian vegetation associated with eastern (upstream) portion of Big Canyon Creek during focused riparian bird surveys conducted between April and July 2015. Yellow warbler was identified in four locations within the riparian vegetation throughout Big Canyon Creek during focused riparian bird surveys conducted between April and July 2015 (Figure 4). No special - status bird species were detected within the Pepper Tree or Myoporum Groves Semi -natural Stands vegetation community located toward the center of the study area and Big Canyon Creek. 4 DISCUSSION The BCNP study area consists of approximately 88 acres of land characterized by a variety of natural vegetation communities and land covers that provide habitat for special -status species. Known or potential constraints to the restoration and future management of the BCNP include the presence of special -status vegetation communities, special -status plant species, special -status wildlife species, and invasive species. 4.1 Special -Status Vegetation Communities Thirteen special -status vegetation communities were identified within the BCNP study area. These vegetation communities are either recognized as special -status by the CDFW (2010) and/or recognized as a covered habitat type within the Central -Coastal NCCP/HCP (i.e., coastal sage scrub habitats), and are listed below: California Brittle Bush Alliance, Associations and Mapping Unit California Sagebrush Alliance, Associations, and Mapping Unit Fourwing Saltbush Alliance and Mapping Unit Lemonade Berry Alliance Alkali Heath Marsh Alliance California Cordgrass Marsh Alliance Pickleweed Mats Alliance 8811-09 Q U Q E K 28 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California To the extent possible, special -status vegetation communities should be restored and protected during future restoration activities. Installation of signs and fencing to prohibit trespassing into these areas should be considered during future restoration and/or management practices. Invasive and non-native plant removal is encouraged to improve habitat quality within these special -status wetland and coastal sage scrub habitats. 4.2 Special -Status Plants Four special -status species were identified within the BCNP study area during focused plant surveys (Roberts 2015): southern tarplant (CRPR 1B.1), southwestern spiny rush (CRPR 4.2), California boxthorn (CRPR 4.2), and woolly seablite (CRPR 4.2). Southern tarplant. A total of 21 sites supporting 1,025 individuals were located in western (lower) Big Canyon. The majority of the individuals were located along the disturbed margin of the Central Fire Road. Two of the sites identified by Bramlet in 1990 (Gardnier 1997, CNDDB 2010) were not relocated. Shading is presumable more pronounced in 2015 than it was in 2003 and is likely a contributing factor at these two locations. Southwestern spiny rush. A total of 286 individuals were documented spread over 18 locations within the BCNP study area during 2015 surveys. These species were primarily observed along Back Bay Drive and the Big Canyon Loop Trail. California boxthorn. A total of 18 sites supporting 50 individuals (estimated) occur primarily on the coastal bluff slopes along the northwestern edge of the BCNP study area. These sites were consistent with previous locations identified in Bramlet (2003), with one new site encountered. Woolly seablite. One site supporting 5 individuals occur on the steep, northwest -facing slopes east of the Big Canyon Parking area. This species has not been previously documented from the study area, but is well known from adjacent areas. To the extent possible, special -status plant locations should be protected from future restoration activities and pedestrian traffic. Installation of signs and fencing that prohibit entrance into these areas should be considered during future restoration and/or management practices. It is recommended that exotic plant species be removed along the canyon floor and on the surrounding slopes to significantly improve the opportunities for special -status plant species occurrence. 8811-09 Q U Q E K 29 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California 4.3 Special -Status Wildlife The coastal scrub, riparian scrub, and wetland habitats provide suitable habitat for special -status wildlife species that known to occur in the vicinity of BCNP. Six special -status bird species were observed within the BCNP study area in 2015: coastal California gnatcatcher (FE; SSC; Central - Coastal NCCP/HCP covered species); red -shouldered hawk (Central -Coastal NCCP/HCP covered species); white-tailed kite (FP); osprey (WL); yellow -breasted chat (SSC); and yellow warbler (SSC). No other federal- or state -listed wildlife species were detected within BCNP study area during surveys conducted in 2015. A complete list of wildlife species observed within the BCNP is included as Appendix B. Coastal California gnatcatcher. One pair of coastal California gnatcatchers have been consistently observed within the coastal California gnatcatcher use area (coastal scrub habitats located in the southwestern portion of the study area) since 2003 (Figure 4). Red -shouldered hawk. A red -shouldered hawk was observed soaring over BCNP during a focused riparian bird surveys. White-tailed kite. An individual white-tailed kite was observed flying over the western and central extent of the BCNP study area during a focused riparian survey conducted in 2015. Osprey. An individual was observed perched on the mudflat in the western part of the study area during a focused survey conducted in 2015. Yellow -breasted chat. This species was observed in two locations within riparian scrub in the upper reach of Big Canyon Creek. Yellow warbler. This species was observed within riparian scrub along the upper and lower reaches of Big Canyon Creek. However, this species was not detected within the pepper tree or myoporum groves semi -natural stands that dominate the central and eastern portions of the BCNP. Conservation of coastal scrub habitat is necessary in order to maintain the long-term net habitat value of the coastal scrub habitats for coastal California gnatcatcher within BCNP. To the extent possible, coastal scrub locations should be protected from future restoration activities and pedestrian traffic. Installation of signs and fencing that prohibit entrance into these areas should be considered during future restoration and/or management practices. Additionally, it is suggested that effective coastal sage scrub habitat be created when feasible. �+� 8811-09 V U Q E K 30 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California The riparian scrub (arroyo willow disturbed mapping unit) provides suitable habitat for riparian birds and nesting raptors (nesting raptors are discussed further in Section 5.4 Nesting Birds and Raptors below). However, the riparian scrub within BCNP is characterized by areas of disturbance. Additionally, special -status riparian birds observed within BCNP did not occur within the pepper tree or myoporum groves semi -natural stands located within the central and eastern portions of Big Canyon Creek, likely because the pepper tree or myoporum groves semi- natural stands do not provide quality habitat for special -status riparian bird species. Restoration and enhancement actions in these areas should be considered during future restoration and/or management practices. Invasive and non-native plant removal and native planting programs are encouraged to improve habitat quality within these special -status wetland and coastal sage scrub habitats. Additionally, it is suggested that effective riparian, wetland, coastal sage scrub and other habitat be created when feasible. 4.4 Nesting Birds and Raptors Active bird nests are protected by the California Fish and Game Code (CFGC) Section 3503.5 and the Migratory Bird Treaty Act. Management activities that result in significant ground disturbance should be implemented outside of the nesting season (February through August). If ground -disturbing activities are conducted during the nesting season, then a nesting bird survey is typically conducted prior to activities to identify any active nests. If active nests are found, appropriate measures should be implemented under the direction of a qualified biologist to ensure compliance with the CFGC and MBTA. Several species of raptors forage and may nest on the site including Cooper's hawk, white-tailed kite, red -shouldered hawks, and red-tailed hawks. Although raptor species were not found nesting on the site, the mature trees associated with the surrounding ornamental land covers and riparian woodlands associated with Big Canyon Creek provide suitable nesting habitat for raptor species. Like other bird species, active raptor nests are protected by the CFGC and MBTA and appropriate measures should be implemented to protect active nests. 4.5 Invasive Species Several invasive plant and wildlife species were found within the BCNP and are discussed below. 4.5.1 Exotic Trees and Invasive Plants Brazilian peppertree is the primary exotic tree of concern. Brazilian peppertree is dominant in patches within the central and eastern portion of the BCNP, replacing natural riparian vegetation �+� 8811-09 V U Q E K 31 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California within Big Canyon Creek. Other primary exotic plants of concern throughout the BCNP include black mustard (Brassica nigra), and ngaio tree (Myoporum laetum). Brazilian peppertree. The Brazilian peppertree is an evergreen shrub or tree that is native to Argentina, Paraguay, and Brazil, and occurs within the Anacardiacea family. This species is a pioneer of disturbed sites, as well as undisturbed wildlands, that spreads aggressively and prefers riparian areas, canyons, fields, and roadsides where some water is available throughout the year. The species is characterized by small, white flowers and pink to bright red fruit. This ornamental species outcompetes other native species due to its dense canopy that shades understory species. Additionally, the species produces allelopathic chemicals in the soil that inhibit growth of other plants. Peppertree infestations are commonly controlled by removing or killing tree roots and hand -pulling seedlings for at least three years. Brazilian peppertrees are dominant in patches within the central and eastern portion of the BCNP. Peppertree is intermixed with disturbed arroyo willow riparian forest associated with Big Canyon Creek. Black mustard. Black mustard is a winter annual herb/forb within the Brassicaceae family. This species is a common invasive that grows in a variety of vegetation communities. Black mustard is characterized by its bright yellow, 4 -petaled flowers that bloom from March to June. This species outcompetes other native species due to its rapid growth and heavy seed production that results in dense monocultures. Additionally, black mustard produces allelopathic chemicals that prevent germination of native plants. Mature plants are commonly managed by physical removal. Mowing is generally ineffective at eradicating mustard. Black mustard dominates the ruderal areas of BCNP and is occasionally found invading annual grasslands and California buckwheat scrub primarily located along the southern and eastern portions of BCNP. Ngaio tree. The ngaio tree (myoporum) is an evergreen shrub or small tree that is native to New Zealand and occurs within the Myoporaceae family. This species is a common landscape ornamental that grows to form dense stands and favors coastal areas, woodlands, and riparian areas. Ngaio trees are characterized by a broadly spreading crown and have white flowers with purple dots and reddish -purple fruits. This ornamental species outcompetes other native species due to its heavy seed production that results in dense monocultures. Additionally, its leaves and fruits are toxic and may be fatal to livestock. Mature plants are commonly treated by cutting at ground level and painting the stump with an herbicide. Moderate densities of nagio trees were found within the central portion of BCNP. �+� 8811-09 V U Q E K 32 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California Other secondary exotics identified during 2015 surveys within the BCNP include ash, Canary Island date palm, Chinese flame tree, eucalyptus, Ficus, goldenrain tree, and Mexican fan palm, Italian thistle (Carduus pycnocephalus), sweet fennel (Foeniculum vulgare), annual yellow sweetclover (Melilotus indicus), blessed milkthistle (Silybum marianum), Uruguayan pampas grass (Cortaderia selloana), sea fig (Carpobrotus chilensis), cultivated radish (Raphanus sativus), and salt cedar. Invasive plant species degrade existing native vegetation communities and reduce biodiversity by outcompeting native plants for resources and habitats. Invasive plant species that occur along recreational trails in the north -central portion of the BCNP as well as areas immediately adjacent to the BCNP have the potential to encroach and thus impact existing vegetation communities. Invasive plant species control methods should be considered during future restoration and/or management practices. Invasive and non-native plant removal is encouraged to improve habitat quality within native habitats. 4.5.2 Invasive Aquatic Wildlife Primary invasive wildlife species detected within BCNP include African clawed frog, red swamp crayfish, and American bullfrog. African Clawed Frog. The African clawed frog is originally native to South Africa and was introduced to North America in the 1940's and 1950's for medical research and later as an aquarium pet (Tinsley and McCoid 1996; Tinsley et al. 2009). This species is now considered a resident in nine states, including California, and escaped individuals are permanent occupants in ponds, lakes, and rivers throughout southern California, including Orange County. Aided by their high fecundity, their ability to reproduce under a wide variety of environmental situations and to inhabit temporary water bodies (e.g., man-made ponds, irrigation channels), and that they are non-selective eaters, the African clawed frog is a successful invader of novel habitat (McCoid 1980; Somma 2013). This species has adapted to survive in a wide range of environmental conditions, including desert habitat, ice -covered lakes, brackish habitats, and evaporated ponds (Trueb 2003; CalifomiaHerps 2015). The African clawed frog has small front limbs and powerful long webbed hind legs used in feeding (Stebbins 2003). The frog has a smooth, slick skin and secretes a mucus that is distasteful to predators (Somma 2013). This species has mechanoreceptors on its back that enable the individual to detect movements made by other species and better locate prey (Bleckmann 2008). This species rarely leaves aquatic habitats, only making short overland �+� 8811-09 V U Q E K 33 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California migrations during rainy weather or humid nights (Somma 2013). Human -induced dispersal has likely led to this species' current range (McCoid 1980; Somma 2013). African clawed frogs were trapped in the upper and middle reaches of Big Canyon Creek, but assumed to occur throughout Big Canyon Creek. Red Swamp Crayfish. This species is the predominant crayfish species present in California and due to fostered and accidental releases and invasions has become a world-wide pest species (Dorn et al. 2006; Henttonen and Hunter 1999; Crandall 2010). This species is used as a source of food, bait, and pet, and is native along the Gulf Coast from northern Mexico to Florida and inland to southern Illinois and Ohio (Crandall 2010). The red swamp crayfish may occur in most primarily freshwater body of water including rivers, ponds, lake margins, irrigation features, and water treatment facilities, and is most commonly found in warm fresh water. They are known to have a high tolerance for typically poor conditions, such as severe temperature fluctuations, poor water quality, low oxygen concentrations, salinity, and drying (Bonvillian et al. 2012, Dorr et al. 2006; McClain and Romaire 2007; Hyatt 2004). Red swamp crayfish are omnivores and scavengers that will eat nearly anything they can find or catch (e.g., plants, algae, invertebrates, fish and old exoskeletons. Burrows provide protection from predators, the elements, and are required for breeding; thus, are a very important part of crayfish ecology. The red swamp crayfish typically dig burrows at the water's edge or in nearby puddles, but occasionally will dig burrows under water (Gherardi et al. 2000). Although the red swamp crayfish can spawn year-round, spawning peaks in the autumn (Gherardi et al. 2000; Dor etl al. 2006; McClain and Romaire 2007). Red swamp crayfish were observed and trapped in the upper and middle reaches of Big Canyon Creek, but assumed to occur throughout Big Canyon Creek. American Bullfrog. This species is a voracious, omnivorous predator that preys on a variety of small native species. The American bullfrog has become a pest, eating other species, directly outcompeting them, and causing reproductive interference by attempting to mate with other species (D'Amore et al. 2009). The presence of emergent vegetation is needed to provide suitable cover for this species. The availability of both shallow and deep water fulfills life cycle requirements—shallows allow for feeding and basking, and deep water provides cover for tadpoles and aestivation (Zeiner et al. 1988). The American bullfrog is rarely found far from water, as individuals generally remain in one pond or in a series of ponds. Breeding occurs in slow-moving bodies of water or permanent water sources, such as lakes and ponds. Mating and egg laying occurs mostly from May to late August, but may occur from March to October if temperatures are moderate. Females can lay multiple clutches of up to 20,0000 eggs that occur as floating mats, which sink just prior to hatching 8811-09 D U D E K 34 August 2015 Dr. Riley Pratt Subject: Biological Resources Inventory Report for the Big Canyon Nature Park Project, City of Newport Beach, Orange County, California (Bury and Whelan 1984; Hammerson 1999). Eggs hatch after 3 to 5 days with metamorphosis ranging from a few months and 2 years. Males reach sexual maturity in 1 to 2 years and females in 2 to 3 years (Bury and Whelan 1984; CaliforniaHerps 2013). One American bullfrog was observed within the lower reach of Big Canyon Creek at the trail parallel to Back Bay Drive, but also assumed to occur within the open water/freshwater marsh area and throughout Big Canyon Creek. Due to the perennial surface water flows and lack of any natural or man-made breaks within the channel, it is assumed that the entire length of Big Canyon Creek supports large numbers of African clawed frogs and red swamp crayfish, and to a lesser extent, American bullfrogs. Additionally, the ponds and waterways within the Big Canyon Golf Course support large populations of African clawed frogs and are hydrologically connected to the BCNP. The open water/freshwater marsh vegetation communities provide suitable habitat for the American bullfrog. Invasive wildlife species reduce biodiversity by outcompeting native species for resources and habitats. Invasive animal species control methods should be considered during future restoration and/or management practices.

The mouth of the Canyon is largely owned and managed by the state of California Department of Fish and Wildlife (CDFW) as part of the Upper Newport Bay Ecological Reserve. The majority of the canyon is owned by the City of Newport Beach and managed by the New Irvine Ranch Conservancy as the Big Canyon Nature Park. The canyon has a long history of disturbance and by the time the State and City took management, tidal wetlands at the mouth of the canyon had long been converted to evaporation ponds for harvesting salt, been buried under silty fill, and partially restored to brackish marsh. The upper canyon, once with a fairly narrow and intermittent watercourse runs year-round with urban runoff. Little of the original natural habitat remains and non-native plants, especially peppers, ash, acacia, and saltbush present a vista that looks like natural forest and scrub to the untrained eye. Several efforts have been made to restore the vegetation of Big Canyon to something a bit closer to a natural state with native species the primary inhabitants. The current survey, in anticipation of future restoration work, was commissioned to provide an accurate census and locational data for the rare, sensitive, and endangered plant taxa that are known or expected to occur within Big Canyon. The survey overall, includes about 60 acres, including both City of Newport and CDFW lands. The report also provides some recommendations in terms of the relationship between insitu preservation of existing, largely disturbed habitat and how restoration can benefit or impact these species. 2.0 PHYSICAL SETTING Big Canyon is situated along the eastern flank of Upper Newport Bay on the coastal plain in western Orange County about 4 kilometers (2.5 miles) from the Pacific Ocean. It is found on the Newport Beach 7.5 minute U.S.G.S. quadrangle (See Figure 1) and is in part, within the jurisdiction of the City of Newport Beach. Big Canyon has an east -west axis with the mouth at the west end. The Study Area, encompassing about 60 acres rises from sea level in the west to about 18 meters (60 feet) above sea level at the eastern end in the floor of the canyon, about 18 meters (60 feet) along the north rim, and 30 meters (100 feet) along the south rim. The Study area is bounded by Back Bay Drive on the west, Jamboree Boulevard on the east, and residential development on the north and south (See Figure 2). The main features of Big Canyon are the canyon floor, north and south bluff slopes, year-round watercourse, and three trail or road systems, Big Canyon Loop Trail, Back Bay Bluffs Spur Road, the Central Fire Road and Eastern Fire Road. The terrain at Big Canyon is dominated by a relatively broad, near flat canyon bottom in the west, narrowing toward the east, with steep bluff slopes on the north and south sides, these moderating in steepness, becoming rather gentle near Jamboree Boulevard. The central stream course, historically intermittent, now generally flows year round. A large brackish basin, filled with water in wet years, is located in the center west at the mouth adjacent to Back Bay Drive. The floor of the canyon on the south side at the west end is dominated by a low, somewhat dome-shaped old fill mound. The Soils Conservation Service (USDA 2015) classifications for Big Canyon appear to be somewhat unreliable or oversimplified for the floor of the canyon. For example lower Big Canyon is classified as Beach, where from the background aerial suggests recently placed fill, most likely silty -clay and sand mix, then sand. The central floor of the canyon floor is classified as tidal flat, which at least has not been true since before 1878. The upper canyon and bounding slopes are probably more reliably classified. The upper floor is classified as Sorrento clay loam or Anaheim clay loam. The slopes are classified as Anaheim clay loam, Calleguas clay loam, or Cieneba sandy loam. The vegetation at Big Canyon is fairly complex, largely because of a high abundance of non-native trees, shrubs, and perennials, broad swaths of secondary native vegetation slowly recovering from major disturbances of the last 3 JIF Im SO ` 3 ' 4 Lai' fl. O . 97 i CL O, tj } O y W m Bay Or��e RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH century, and isolated pockets of natural primary vegetation that were likely not significantly impacted in the last century. Although not without errors, the vegetation map found on Appendix A2 of the Big Canyon Creek Historic Tidal Wetlands Conceptual Restorarion Plan (Restoration Plan) (Community Conservancy International 2004), presents a reasonably accurate map of the vegetation though a number inaccuracies are in the map based on field observations (or example, most of the "coastal sage scrub" on the south slope is dominated by the exotic, swamp saltbush (Atriplex amnicola) and there are very few true coastal sage scrub species present). The floor of the western canyon includes a freshwater pond bordered by freshwater marsh, heavily dominated by thick stands of cattail (Typha domengensis and Typha latifolia) and California bulrush (Schoenoplectus califronica), with riparian forest north of the pond and largely bounded by Big Canyon Loop Trail. The forest is primarily a willow riparian forest of arroyo willow (Salix lasiolepis) and black willow (S. gooddingii) with a moderate invasion of Brazilian pepper (Schinus terebenthifolia) and other non-native species. Some impressive stands of Japanese honeysuckle (Lonicera japonica) and trailing African daisy (Dimorphotheca ecklonis) have become established in this forest. Along Back Bay Drive, there are wet alkali meadows and narrow brackish marshes dominated by common woody pickleweed (Salicornia pacifica), saltgrass (Distichlis spicata), alkali heath (Frankenia salina), alkali bulrush (Bolboschoenus maritimus), and fleshy jaumea (Jaumea carnosa), and baccharis scrub, dominated by coyote brush (Baccharis pilularis) with some willow baccharis (B. salicina), and Brazilian pepper. The dredge -spoils mound south of Back Bay Spur road were mapped as annual grassland in 2004 but the mound is largely barren today with scattered large non-native and a few native shrubs such as coastal wattle (Acacia Cyclops), big saltbush (Atripex lentiformis), coast goldenbush (Isocoma menziesii), and swamp saltbush. Scattered plantings from earlier restoration efforts also pepper the mound, including the odd addition of dark -tipped bird's beak (Cordylanthus rigidus). The southern portion of the lower canyon floor and southern bluff slopes were classified as coastal sage scrub in the 2004 Restoration Plan but the majority of the scrub is dominated by dense stangs of Swamp saltbush with small patches of coastal sage scrub, mostly consisting of California sage brush. The steep bluff slopes along the northern edge of the lower canyon were classified in the Restoration Plan as coastal sage scrub with ornamental plantings and woodland. The scrub here is better described as coastal bluff scrub and is a mixture of California boxthorn (Lycium californicum), California buckwheat (Eriogonum fasciculatum), California sagebush, lemonade berry (Rhus integrifolia), coastal cholla (Cylindropuntia prolifera), and prickly pear cactus (Opuntia littoralis and Opuntia oricola). A relatively large patch of blue elderberry (Sambucus nigra) is also found on the slope. The upper margin transitions into landscaping but a few interesting exotics are either persisting from earlier plantings or have become established on this slope including false sisal (Agave decipiens), candelabra alow (Aloe arborescens), and soap aloe (Aloe maculata). Toward the center of the canyon, where the valley floor rises and the bounding slopes moderate, the coastal bluff scrub is gradually replaced by a mixture of coastal sage scrub and four -winged saltbush (Atriplex canescens) dominated saltbush scrub. The vegetation of the canyon floor is dominated by Brazilian peppertree and shamel ash (Fraxinus uhdei). The southern slopes are dominated by swamp saltbush scrub grading into ornamental landscaping at the top of the hill. Farther up the canyon, as the southern slope becomes more gentle, the landscape intrudes farther into the canyon. The upper canyon is dominated by a mixture of Brazilian pepper and shamel ash forest, freshwater marsh, wet meadows, and annual grassland. A line of lemonade berry shrubs growing along Jamboree, likely planted, forms an effective narrow band of sumac chaparral. 2 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH Throughout the entire canyon there are small patches of unique habitats. For example, there are small patches of mesic native wet grasslands dominated by beardless wildrye (Elymus triticoides) flanking the southern side of the pepper and ash forest. There are also prominent individuals of Italian buckthorn (Rhamnus alternus), and a few scattered plantings of western sycamore (Platanus racemosa) and Fremont cottonwood (Populus fremontii) scattered throughout the lower section of the canyon. While the vegetation on the steep bluff slopes in the western half of Big Canyon represent isolated bands of habitat that are at least similar to and have persisted without major soil disturbances since historic times (primary vegetation), virtually the entire floor of the canyon and much of the southern slope represents recently established habitat recovering from past soil disturbance, removal, or dumping (secondary vegetation). In general, this vegetation has only been established in its current form over the last 10 to 50 years. Large-scale disturbance of this scale has significant consequences for floristic diversity, favoring introductions, and rare plants, which often have reduced diversity. Tidal flats and coastal salt marsh once covered much of the lower region of Big Canyon. As shown on a nautical chart, Newport Entrance, Los Angeles County, California, dated from 1878 and issued in 1880 by the U.S. Coast and Geodetic Survey office, the tidal wetlands once extended about 280 meters (920 feet) east of Back Bay Drive, roughly to the ford over the creek along the connector between the North Fire Road and Back Bay Drive Spur Road (See Figures 3 and 3b). Community Conservancy International (2004) indicates states that "Natural tidal flow into Big Canyon was destroyed in the 1930s with the construction of Back Bay Drive, which effectively created a ten -foot high dam and destroyed more then five acres of tidal wetlands." However, I have seen an Automobile Club of Southern California map of Orange County shows a presumably dirt road linking the Coast Highway with Lane Road, now in Irvine. The road, likely an early version of Bayside Drive, the older name for Back Bay Drive, runs along the east side of Tidal mud flats & coastal salt marsh 1 Approximate crossing of Back Bay Drive O �D Figure 3. 3a (left) the nautical chart, Entrance to Newport Bay, Los Angeles County, California, U.S. Coast and Guard, 1878. 3b (right), an expanded section of the 1878 chart focusing on Big Canyon.

The current alignment of Back Bay Drive, the trails, and Jamboree Blvd. are in red [mapped traced from the 1878 chart]. 7 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH Upper Newport Bay following the current path of Back Bay Drive so it is possible the tidal flow was interrupted at least 15 to 20 -years earlier then reported by Community Conservancy International. Figure 4: A 1938 aerial photograph showing Big Canyon and the immediately surrounding areas. Note the lack of perennial watercourse in the upper canyon and grassland cover. The vegetation in areas marked as tidal in 1878 already have well developed upland vegetation (mostly annual grassland) but 1938, supporting Automobile Club of Southern California maps indicating the road was present as early as 1920. Figure 5: A 1952 aerial photograph showing Big Canyon and the immediately surrounding areas. Regardless of conditions in the lower canyon in 1938, the lower canyon habitat of 1952 is greatly disturbed. The upper canyon is undergoing some form of cultivation or ranching activity. Still no significant water sources feeding the canyon. a w z Regardless, a 1938 aerial photograph of Big Canyon (See Figure 4) available from NETR online, clearly shows that Bayside Drive had been constructed by that year. The habitat immediately east of the road toward the north shows what could be alkali flats but toward the south, the photo shows what looks to be an alluvial spreading zone. The rest of the lower portion of the canyon appears to be annual grassland with some shrubs and a narrow, braded dry watercourse. The appearance suggests that upland habitat was already well established by the late 1930s. The construction of the future Back Bay Drive must have taken place long before 1938. The upper portion off the canyon appears to be annual grassland with a few trees along the dry streambed and at least one structure, probably a house. The bluff tops to the north and south of the canyon appear to be rather uniform annual grassland. Narrow lines visible on the bluff tops suggest these areas had been disced prior to 1938. 0 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH The coastal bluff slopes along the northern margin of the canyon show habitat much as it appears today. Some bald patches and irregular markings suggest some of the habitat along the northern rim has not been disturbed or has been to a lesser extent and likely host many herbaceous annuals and perennials either missing or scarcely found today at Upper Newport Bay. A 1952 aerial photograph of Big Canyon (See Figure 5) available from NETR online, shows the distinctive texture of shrubby vegetation throughout much of the canyon. However, the main watercourse remains intermittent and is probably dry at the time of photograph was taken. The upper portion of the canyon clearly shows greater impact with either corrals or plots for cultivation covering much of the canyon floor. Of interest the photograph captures the future alignment of Jamboree Parkway. Evidently, the initial clearing of habitat for the road took place late in 1951 or early in 1952. The eastern border of Big Canyon Nature Park is now evident. The lower portion of the canyon is more disturbed then indicated by the 1938 photograph. Material has been piled and spread in three overlapping piles. Based on its light color, sand is a likely candidate. Alkali flats continue to persist about where the Big Canyon Loop Trail and Back Bay Drive intersect. Note that the main watercourse appears to flow out the southern side of Big Canyon in 1952. The final photograph in the series I have included here, is a 1963 image of Big Canyon, again sourced from NetR online (see Figure 6). In this photograph, the Corona Del Mar High School has been built and some surrounding areas cleared. Jamboree Road is now constructed as a two-lane road. The southern bluff top is still dominated by annual grassland. Of interest, the southern slopes descending down into Big Canyon also appear to be uniform grassland habitat. Today, these are shrublands, from a distant reminiscent of coastal sage scrub but largely dominated by swamp saltbush. The structure and associated disturbance of 1952 are no longer present in 1963 and the habitat would appear to be annual grassland, perhaps with some shrubs like coast goldenbush, and a few trees. Shrubby vegetation still appears to occupy the central canyon floor. The primary watercourse is not obvious in this photograph. Urban runoff was not yet a factor. Just off the east side of the photograph, the massive Ford Aeronutronics project has just recently been completed, a harbanger of the rapid changes about to take place in the region. At this time, the complex stands largely alone without its attendant residential development. The lower end of Big Canyon has completely been filled, presumably with sand or dredgings from Upper Newport Bay. There is natural habitat left along the western canyon floor at this time. By 1972, residential development crowns all the mesas adjacent to Big Canyon and urban runoff is having a clear impact on the remaining wild - Figure 6: A 1963 aerial photograph showing Big Canyon and the immediately surrounding areas. Farming or ranching activities have been removed from the upper canyon. The lower canyon habitat has been completely removed and is now filled. Corona del Mar High School has been built on the north mesa. Many student plant collections were made by students at Corona del Mar High School in 1965. Generally, their locality data is vague but it is interesting to ponder how many were taken from the canyon just south of the high school. 9 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH lands along the canyon floor. A forest is already visible in the central canyon and spreading somewhat into the upper canyon. These photographs clearly document that, with the exception of the bluff slopes above Big Canyon Loop Trail, all the vegetation must be of relatively recent origin. The heavily invaded riparian forests date back to perhaps the late 1960s. Areas mapped as coastal sage scrub in Community Conservation International 2004 that are really domi- nated by the invasive swamp saltbush, can be no more then 50 -years old and are probably much younger (the first aerial images I can find that definitely show the swamp saltbush dominated scrub date from about 2002 (Google Earth)). The riparian and wetland vegetation at the base of the canyon likely became established between 1980 and 1995 and is even younger. In terms of native plant diversity and rare plants, historic photographs, especially in association with the loss of associated adjacent upland habitat, suggest that Big Canyon would be expected to have a lower diversity of native species then areas that have a longer undisturbed or less disturbed history. Rare plants especially, because many are uncommon to start out with and often have narrower habitat requirements, are less likely to be found in recovering habitat. On the other hand, habitat that has been recovering for over 30 -years begins to recover some of its original natural diversity. 3.0 PREVIOUS STUDIES Robert DeRuff compiled the first comprehensive list of plant species for Upper Newport Bay as an ongoing project from the mid 1980s through about 2010. DeRuff's work is posted online (florauppemewportbaycal.net) and can be useful to determine potential species and identify them. However, with a few exceptions, it is not possible to determine which plants DeRuff found at Big Canyon. Specific locality data is generally not supplied. A number of environmental studies have been conducted in the vicinity of Big Canyon and presumably, all of these included rare plant surveys. I have only been able to obtain survey results for one study that included specific locality data for sensitive plants, Botanical Resources in the Big Canyon Creek Area August 2003. The report was prepared by David Bramlet for Keane Biological and was the basis for rare plant data, plant speciees list and to some extend, descriptions of vegetation utilized in a broader 2004 restoration study titled Big Canyon Creek, Historic Tidal Wetlands Conceptual Restoration Plan, Upper Newport Bay, Orange County, California. The report was directed and developed by Community Conservancy International. Keane Biological prepared the biological assessment for this later report. The Bramlet report covered both sides of Back Bay Drive and included areas outside the current Study Area. Locality details were included, enabling separation of rare plants both west (outside the current Study Area) and east of Back Bay Drive (largely inside the Study Area). A few errors in the coordinates required some modification, and I was able to contact Mr. Bramlet to help clarify some of these errors (D. Bramlet, consulting botanist, Santa Ana, California, pers. comm. July 2015). Bramlet located six sensitive plant species during the spring of 2003. These included southern tarplant (Centromadia parryi subsp. australis), Saltmarsh bird's beack (Chloropyron maritimum subsp. maritimum [as Cordylanthus maritimus subsp. maritimus]), a state and federally listed endangered plant, California boxthorn (Lycium californicum), estuary sea-blite (Suaeda esteroa), woolly sea-blite (S. taxifolia), and southwestern spiny rush (Juncus acutus subsp. leopoldii). Saltmarsh bird's beak and estuary sea-blite locations were entirely on the west side of Back Bay Drive and outside our study area growing along the upper margins of tidal coastal salt marsh. Bramlet located one site for woolly sea-blite east of Back Bay Drive, but the site is outside the current survey area at the bend in Back Bay Drive southwest of the Study Area along the cliffs overlooking the road. The other wooly sea-blite sites were also found west of Back Bay Drive. 10 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH Three of the sensitive species located in 2003 are within the boundaries of the current Study Area, southern tarplant, southwestern spiny rush, and California boxthorn (see Figure 7). A total of six sites were reported for southern tarplant with a count of 1,694 individuals. These were primarily found along the Big Canyon Loop Trail and between the Central Fire Road and the Back Bay Bluffs Spur Road. A small population of four individuals was also reported along the Back Bay Bluffs Spur Road in the upper (eastern) portion of Big Canyon. Additional sites were found on the west side of Back Bay Drive immediately adjacent to the current Study Area. Two locations of southwestern spiny rush including 36 plants were reported within the current Study Area either along Back Bay Drive or Big Canyon Loop Trail. Six sites for California boxthorn were reported supporting a total of 33 shrubs. These primarily situated along the northern slopes of Big Canyon, especially in the vicinity of where the trail intersects with Back Bay Drive. Three shrubs were found on the slopes above the fire road in the east - central portion of the Study Area. 4.0 METHODS During the course of the survey, a review of previous studies conducted within or adjacent to Big Canyon suggested locations that needed to re-examined. Also a review of herbarium specimens in the Consortium of California Her- baria (Consortium) and the Bramlet Study (2003) for previously reported plant species was conducted early during the survey time frame. The California Native Plant Society's (CNPS) online Inventory of Rare and Endangered Species (CNPS 2015) and data from the California Natural Diversity Database supplied by the New Irvine Ranch Conservancy in association with herbarium records was consulted to determine known and potential rare plant spe- cies in Big Canyon. Field surveys of Big Canyon were conducted on April 1611, April 23rd, April 28th, June 22nd, and July 1, 2015 (See Figure 8). Wandering transects were conducted generally in areas that were accessible, especially along trails. Spe- cial attention was paid to areas that represented primary habitat. Many of these areas were also difficult to access due to steep slopes and friable soils so they were not as thoroughly examined as perhaps warranted. When the author was aware of previously identified sensitive species sites, these sites were revisited. Observed plant species were recorded and compiled into a comprehensive list (See Appendix A). Vouchers were obtained for a limited number of taxa, especially poorly documented non-native species but occasionally some important native plants. Vouchers were taken primarily for later verification of identifications. Any vouchers ob- tained will be deposited either at the Santa Ana Botanical Gardens at Claremont (RSA) or University of California, Riverside (UCR) herbariums, both when duplicates were obtained. When rare or sensitive plants were encountered, these were recorded on a Garmen Map60CSX hand held GPS unit.. In most cases, the site is represented by a single GPS point. If an extended population was present, the site could be represented by a combination of a point and a polygon. Due to the steep nature of slopes bordering parts of Big Canyon, some plant sites were hand -sketched and later translated into digitial polygons using Google Earth. Gen- erally, these sites were hazardous to examine, access could result in soil damage, and the Garmen GPS unit data is not very accurate on steep slopes. All GPS readings were taken in Universal Transverse Mercator (UTM) units with a WGS 84 Datum. Notes for rare and sensitive species were recorded on standardized data forms. Each record was assigned a GPS code based on the first letter of the genus and species of the target species, followed by a number representing the consecutive number of finds during the survey day. On the form, it was noted whether a photo was taken, the num- ber of individual plants that were observed, the percentage of plants that were in vegetative, bud, flower, or fruit; along with aspect, slope, soils, habitat, and associated species. These data are summarized in section 6.2 and Appendix B. 11 RARE AND SENSITIVE PLANTS OFBIG CANYON NEWPORT BEACH 12 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH Figure 8: Survey routes for the Big Canyon rare plant surveys. The survey dates are color -coded: April 16, 2015 (magenta), April 23, 2015 (cyan), April 28, 2015 (white), June 22, 2015 (orange), and July 17, 2015 (orange). Conditions at the time of the survey were dry. The seasonal rainfall pattern prior to the survey was wet early, unsea- sonably dry and hot in the several weeks leading up to the survey. The effects of these conditions on the flora and rare plants are discussed in section 6. The taxonomy and nomenclature for flowering plants discussed in this report generally follows The Jepson Manual of Vascular Plants of California, 2nd edition (Baldwin et al., 2012), the Vascular Plants of Orange County,. an Anno- tated Checklist (Roberts 2008), and in a few cases, publications that were published after the Jepson Manual when it was released, if they differ from the two primary sources. 13 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH 5.0 SENSITIVE, RARE, AND ENDANGERED PLANTS Rare and sensitive plants include those species listed by the state or federal governments as endangered, threatened or rare and species that are candidates for future listing. This group also encompasses the species determined by the California Department of Fish and Wildlife's (CDFW) California Natural Diversity Data Base (CNDDB) program to meet the CEQA (Section 15380) criteria as "rare and endangered, and species identified by the California Native Plant Society (CNPS 2015) of special interest. A nine -map search of U.S.G.S. 7.5 minute quadrangles focused on the USGS 7.5 minute Newport Beach quadrangle yields a total of 45 sensitive plants reported from the general vicinity of the project. One additional species, mud nama (Nama stenocarpum), was not included on the CNPS list but also occurs within the general region. Not all of these sensitive plants can be expected in the Big Canyon or its immediate vicinity. Twelve of these plants are very narrowly distributed in Orange County, require habitat types that are not found in Big Canyon, or are based on erroneous reports. These plants are included on Table 1. The remaining 33 sensitive plants have some reasonable potential or are known to occur at Big Canyon or adjacent areas. The status of these plants and their potential to be found at Big Canyon are summarized in Table 2. CNDDB data supplied by the NIRC indicates that eight of these species, representing California Rare Plant Ranks (CRPR) IA, 113 and 2B have been reported from the immediate vicinity of Big Canyon. Three of these, southern tarplant (Centromadia parryi subsp. australis), many -stemmed dudleya (Dudleya multicaulis), and Los Angeles sunflower (Helianthus nuttallii subsp. parishii) have polygons that overlap with Big Canyon east of Back Bay Drive. The location for Los Angeles sunflower is very speculative. The collection is reported from Newport Beach (L.M. Booth 1388, 26 Aug 1933 [POM, UC]) is described as either from the "far end of Newport Lagoon" (POM) or "Newport Lagoon" (UC). Based on the condition of habitat in Big Canyon five years after the collection was made (NETR online, 1938 aerial photograph, see Figure 4), it is unlikely this wetland obligate species was found in the Study Area and more likely came from another location in the bay. Many -stemmed dudleya is shown to occur in the canyon bottom at the mouth of Big Canyon. However, there is no suitable habitat within the area identified, and likely never has been. The locations for both collections of many - stemmed dudleya upon which the CNDDB report is based, are like the Los Angeles sunflower, very speculative. The earliest collection is from 1882 (J.C. Nevin 698 [GH]). It is known only from "Newport Bay". L.M. Booth collected a specimen on 18 May 1932 (L.M. Booth 1054 [POM, UC]) is reported from an "adobe bluff', Newport Lagoon. Certainly the latter collection came from a bluff top, not the canyon bottom. Even had the specimens come from the vicinity of Big Canyon, the plants would occur on the bluff tops surrounding Big Canyon. These areas are now largely replaced by landscaping and residential development. The plant would never have occurred in the canyon bottom. Regardless, the western canyon bottom has significantly been altered since Booth visited the region eight decades ago. The 1938 NETR online historical aerial photograph (See Figure 4) indicates the area for CNDDB polygon is either salt marsh, open, unvegetated wash, or other disturbed habitat. The 1878 nautical chart for the Newport Bay (See Figure 3b) shows this area as tidal mudflat. Clearly Nevin and Booth found their specimens at some other location at Newport Beach. Ironically, the polygon for southern tarplant as shown in the CNDDB, is too conservative based on knowledge available as long ago as 2003. Element Occurrence 15 is based on data provided in 1997 and has not been updated since that time. 14 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH TABLE 1: SENSITIVE PLANTS OF THE REGION BUT UNLIKELY TO OCCUR AT BIG CANYON Common Name/Scientific Name Rank Comments chaparral sand verbina (Abronia villosa var. aurita) CRPR 4.2 Found in alluvial habitats and sandy opennings in coastal sage scrub and chaparral.

An additional 25 plant taxa that were not observed during the course of the survey have been vouchered by herbarium specimens, increasing the plant list to 199 taxa (Consortium 2015). Only specimens known to occur at Big Canyon east of Back Bay Drive were included in this number. Of these taxa, 79 taxa (40%) are of native origin or are at least native to Orange County, while 120 taxa (60%) are of non-native origin. A com- plete list of plants observed, in addition to those documented by herbarium vouchers from previous years, is found in Appendix A. 6.2 RARE PLANTS Four sensitive plant species at 50 sites were observed within the Study Area. One species, southern tarplant, is a CRPR 1B.1 plant (CNPS 2015). The remaining three species, southwestern spiny rush, California boxthorn, and woolly sea-blite are included under CRPR 4.2. A summary of these plants, rank, and overall groups and numbers of individuals are provided in Table 3. The distribution of these plants at Big Canyon is presented in Figure 9 and Plate 1. Species site-specific data for each site is presented in Appendix B.

A member of the sunflower family (Asteraceae), it blooms from May to No- vember. It frequently favors somewhat saline soils and is found along the borders of salt marshes, water courses, and mesic grasslands. It grows from coastal Santa Barbara County south through Los Angeles, Orange, and San Diego Counties in the United States, and northwestern Baja California, Mexico, from sea level to about 430 meters (1.400 feet). It has also been reported to occur on Santa Catalina Island. Of about 70 known occurrences, nearly 30 percent have been extirpated, primarily within the Los Angeles Basin (CNPS 2015, Roberts 2007). In Orange County, southern tarplant was once widespread on the coastal plains of 22 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH 23 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH western Orange County. Today, it is still known to occur at on the mesas at Bolsa Chica, Mile Square Park, Talbert Regional Park, Newport Back Bay, U.C., Irvine, Mason Regional Park, and various canyons in western Rancho Mission Viejo. Southern tarplant was first recorded in the vicinity of Big Canyon in 1932 (L.M. Booth 1169 [RSA]). It was first reported to occur at the mouth of Big Canyon in November 1990 by Dave Bramlet (Gardiner 1997, CNDDB 2010). Bramlet (2003) reported a total of 12 sites and 2,169 plants in a survey of Big Canyon that included some of the coastal marsh on the west side of Back Bay Drive. Six of these locations, supporting 1,694 individuals were within the current Study area (See Figure 8). 2015 Survey Results: A total of 21 sites supporting 1,025 individuals were located in western (lower) Big Canyon. The majority of these were located along the disturbed margin of the Central Fire Road. Several locations with small numbers of individuals were found along the Big Canyon Loop Trail. Two of the Bramlet sites, one along the northern arm of the Big Canyon Loop Trail and one in the upper portion of the canyon were not relocated. The latter site appears to have been swamped by non-native saltbush. Shading perhaps also was a contributing factor at both of these locations. Shading is presumably more pronounced in 2015 then it was in 2003. See Figure 9, Plate 1 a, and Appendix B. SOUTHWESTERN SPINY RUSH — Juncus acutus subsp. leopoldii CRPR 4.2 Southwestern spiny rush is a dark -leaved spiny perennial herb. A member of the rush family (Juncaceae), it blooms from May to June. It is found from sea level to about 900 meters (2,950 feet) elevation. It is found along the bor- ders of coastal salt marshes, freshwater marshes, rivers, alkaline seeps, meadows, and stream courses from San Luis Obispo County, California, south into Baja California, Mexico. In Orange County, southwestern spiny rush is found primarily along the immediate coast as at the East Garden Grove-Wintersburg Canal at Huntington Beach, Bolsa Chica, Upper Newport Bay, Corona del Mar, Laguna Beach, and Dana Point. A few scarce records have been reported away from the coast as 1.5 km from the ocean in Emerald Canyon (San Joaquin Hills) and near the mouth of Black Star Canyon. A collection taken in 1965 from Silverado Canyon is considered suspect as it is a high school collection. Southwestern spiny rush was first documented in Big Canyon by Bramlet (2003) as a result of surveys in the spring and summer of 2003. Bramlet located five sites and a total of 77 plants on either side of Back Bay Drive (See Figure 8). Four of the five locations were within the current Study Area. These sites supported 76 of the 77 plants Bramlet encountered. 2015 Survey Results: A total of 286 individuals spread over 18 locations were encountered, primarily along Back Bay Drive and along the Big Canyon Loop Trail. Likely as a result of the dry conditions, many individuals encoun- tered in the willow forests near the Big Canyon Loop Trail were in poor condition. Dozens of other plants in this area appeared to be dead and were not included in the survey results. In other areas, especially in the wet ditch im- mediately east of Back Bay Drive, many immature plants were observed, some no more then one or two seasons old, especially in association with site Ja16-08. In 2015, likely due to a warmer then normal winter, many plants were past their peak bloom, which likely occurred in early April. See Figure 9, Plate 1 b, and Appendix B. Note: I seem to recall one additional plant observed on July 11' along Back Bay Drive south of the central fire road intersection. However, if this is the case, a GPS point and data were not collected for the site. Regardless, the ditch along this portion of Back Bay Drive has suitable habitat for this species. 24 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH Plate 1: Photographs of rare plants encountered during the survey. a) soutehrn tarplant (Centromadia parryii subsp. australis); b): southwestern spiny rush (Juncus acutus subsp. leopoldii); c): California boxthorn (Lycium californicum).

Photo taken from west of Back Bay Drive. 25 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH CALIFORNIA BOXTHORN - Lycium californicum CRPR 4.2 California boxthorn is a low, intricately branched, spiny shrub with white flowers and red -orange fruits. A member of the nightshade family (Solanaceae), it blooms generally blooms from January to March, but occasionally later or earlier depending on rainfall. California boxthorn is most common on the Channel Islands and is found on the mainland near the immediate coast from the Palos Verde Peninsula, Los Angeles Co., southward through Orange and San Diego Counties into northern Baja California, Mexico. This species is found in coastal bluff scrub and sometimes in association with estuaries from near sea level to 150 meters (492 feet). It rarely is found in coastal sage scrub habitats near the coast. In Orange County this species was historically found on bluffs in the vicinity of Huntington Beach and Upper New- port Bay south to San Clemente State Park. An isolated small population is known from the San Joaquin Freshwater Marsh near U.C. Irvine (Consortium 2015). A relatively dense stand is also reported from the bluffs north of San Onofre Point and it is reported sporadically on other sea bluffs on Camp Pendleton Marine Corps Base (Reiser 1999). California Boxthorn was first reported from Big Canyon by Bramlet (2003). He located seven sites supporting a total of 40 indivdivals (See Figure 8). Six of the sites and 36 of the indivduals were situated within the current Study Area. One of the Bramlet locations (Lyca Site 4), appears to have the incorrect coordinates based on directions supplied in the report. It appears to be situated near my LcA28-02. Bramlet's Lyca Site 1, just outside the Study Area, also has incorrect coordinates and should be farther west near Back Bay Drive based on location directions. 2015 Survey Results: A total of 50 individuals were estimated to be found at 18 sites, primarily on the coastal bluff slopes along the northwestern edge of the Study Area. The sites found roughly correlate with locations reported in Bramlet (2003) and one clearly new site was encountered. See Figures 8 and 9, Plate lc, and Appendix B. WOOLLY SEA-BLITE — Suaeda taxifolia CRPR 4.2 Woolly sea-blite, a member of the goosefoot family (Chenopodiaceae) is a scruffy grayish -green shrub found along the immediate coast from Santa Barbara County south through Ventura, Los Angeles, Orange, and San Diego Counties, into Baja California and Baja California Sur, Mexico. It is also known from the Channel Islands. Woolly sea-blite is found on beach borders, coastal bluffs, and borders of estuaries in coastal bluff scrub and coastal salt marsh habitats from sea level to 50 meters (164 feet) elevation. In Orange County, it is found at all major salt marshes, including Anaheim Bay, Bolsa Chica, and Upper New- port Bay, inland to San Joaquin Freshwater Marsh, and along the coastal bluffs of Crystal Cove State Beach and Laguna Beach. There are old records for Capistrano Beach and San Clemente from prior to 1938 and it still likely occurs in San Clemente. It has also been reported to occur on the Dana Point Headlands but appears to have been extirpated after 2005. Woolly sea-blite has not been previously documented from the Study Area but it is well known from adjacent areas. Woolly sea-blite was first documented in the Upper Newport Bay region in September 1907 by Antruther Davidson (A. Davidson 1779 [RSA]). It has subsequently been documented by collections at Upper Newport Bay 17 times, including one collection from Big Canyon parking area (D. Newell 299 [UCR]) but presumably on the west side of Back Bay Drive as the specimen is described as growing "beside salt marsh". Bramlet (2003) found woolly sea-blite in four locations with a total of 39 plants. However, all this locations were from west of Back Bay Drive or on the bluffs slopes immediately southwest of the Study Area. 26 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH 7.0 DISCUSSION AND RECOMMENDATIONS A total of 199 plant taxa are here reported for Big Canyon. Fully 60 percent of these taxa are of non-native origin. The high ratio of non-native to native species is a reflection of the degree of secondary and disturbed habitat present in Big Canyon, the proximity and extent of urban/wildland interface, and reliable, mostly year-round water sources. Virtually no areas in the canyon bottom have remained undisturbed over the last 60 -years and for the most part, now represent entirely different habitats then those present early in the last century. The current study, however is not comprehensive. Bramlet (2003), for example, noted an additional 65 additional plant taxa at Big Canyon that were not observed in 2015. The Bramlet survey, included coastal salt marsh areas on the west side of Back Bay Drive so it is possible a significant number of these plants were found outside the Study Area. At least five of his plants (Batis maritima), estuary sea-blite (Suaeda esteroa), California sea -lavender (Li- monium californicum), seacoast -bulrush (Bolboschoenus robustus), and saltmarsh bird's beak (Chloropyron mari- timum subsp. maritimum) are found only in association with tidal coastal salt marsh or its margins, habitat that is not present east of the road. However, while it is uncertain how many of the others were found in the Study Area, suitable habitat for most is present. Likely the most responsible agent for the lower diversity found in 2015 are related to the warm, dry conditions as compared to 2003. It is anticipated that many spring annuals either did not germinate this year, were extremely scarce. The Big Canyon survey also effectively had a late start. Thus some of these plants perhaps already faded or were difficult to identify by mid April, a likelihood increased by the hot dry conditions in March and April. It should also be noted that in coastal canyons with reliable warm weather water sources (coastal marsh, year-round streams) generally will develop a significant flora component in late summer and early fall. Those taxa would likely be missed during surveys focusing on the spring season. In a wetter year, such as 2003, some of those taxa are likely to germinate early and have a better chance of detection than would be the case in a drought year. On the other hand, many of these summer and fall species would likely be non-native in origin. On interesting question that was not resolved at the time of this report is the identity of Robert DeRuff s.n. 11 Jun 2011 (UCR). This specimen, from lower Big Canyon, is reported to be narrow -leaved cattail (Typha angustifolia). If confirmed, it would be the first confirmed record for Orange County. Andrew Sanders, the curator at UCR, is skeptical of the identification and believes it is likely a mis-identified southern cattail (Typha domengensis). I did not see any plants I would call narrow -leaved cattail but I did not examine many cattails in detail. Low rainfall continues, as it has for several to create dry conditions in southern California. The rainfall has been below average, sometimes severely so, for four years in a row, and the state is in a severe drought. At Santa Ana, California, for example, less then 12 kilometers (7.4 miles) from Big Canyon, the average yearly rainfall is 330 mm (12.94 inches). During the 2012/2013 season, only 118 mm (4.64 inches), about 35 percent of normal, fell (NOAA 2015). In the 2013/2014 season, even less fell, 90 mm (3.54 inches), only 27 percent of normal. During the period of November 2014 through January 2015, 120 mm (4.72 inches) of rainfall was measured at Santa Ana, roughly 80 percent of normal (although it should be noted that three quarters of it fell just in the month of December!). Rainfall in the following months was considerably less, only 18 mm (0.71 inches) as compared to 140 mm (5.52 inches), which normally falls during those months. The winter 2014/2015 rainfall pattern was somewhat mixed in terms of rare plant detection. Yet another dry year following several even drier years decreases the potential to find herbaceous species, especially annuals. However, the distribution of the rainfall, with most rain falling early in the season significantly offset the impact of the drought on many species, especially combined with mild winter temperatures. Many plant species bloomed early but a number of species, the herbaceous perennials especially, may have bloomed during their typical blooming period. During the months of January, February, and March the effect of the drought was muted. 27 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH Mid and late March 2015 brought extraordinarily hot and dry conditions to southern California, breaking high temperature records across the region. Combined with dry conditions, the benefits from the early moderate rains rapidly faded. By mid April, conditions were once again much drier then expected for the month. In the case of the Big Canyon surveys, since so much of the habitat is secondary (that is, habitat that has recovered from disturbance), the impact of the drought is probably less critical to the results of a rare plant survey then in other areas. The greatest impact is likely to be on the coastal bluff slopes where earlier blooming species are usu- ally found. These species may already have dried and withered at the time the survey commenced, or were at least more difficult to detect. On the other hand, these areas are also least likely to be impacted either from any future restoration actions due to their steepness. The presence of water in the canyon, though undoubtedly much less then in other years, suggest that the rare plant diversity that would be found in a more favorable year may not differ too much from that in a dry year even if the total number of herbaceous individuals was reduced. This survey found a comparable number of rare plant taxa as compared to Bramlet (2003). However, there were some significant differences. Bramlet found more southern tarplant and this report includes more southwestern spiny rush. It is very likely the southwestern spiny rush population has been steadily growing at Big Canyon. The population is quite mixed between older individuals and young plants. Only a very few very large, and likely very old individuals were found. Many of the plants likely have been established less then 12 years. Bramlet reports a similar number of sites for southern tarplant (when you account for the different ways the authors likely defined site) but about twice as many individuals. I was unable to locate two of his sites, one on the north side of Big Canyon Loop Trail, the other along the Central Fire Road in the upper canyon. The former site is grow- ing along a heavily shaded trail with a fairly crowded understory. This site was perhaps more open in 2003 and has since been shaded out as southern tarplant is typically found in open, sunny locations. There were only a few individuals at the fire road site in 2003 but this site not only is fairly shaded today, but the GPS coordinates match a dense stand of non-native saltbush, which has possibly crowded out the tarplant. Bramlet's site with the most plants was his Cpa Site 7, with over 900 individuals. I did not find any plants corre- lating to his specific GPS point but my CpaL17-04 and CpaL17-05 bracket Bramlet Site 7 and possibly the plants extended between the two points in 2003. However, only six plants were found in this location in 2015. Both surveys found southern tarplant in the vicinity of the western end of the Central Fire Road but Bramlet found more plants toward the west, were there were few in 2015, and current survey found more plants toward the east near the intersection with the Connector Road. California boxthorn is a slow growing shrub. As expected, most of these plants were found in areas that have been less disturbed over the last hundred years. Most are associated with difficult to access steep slopes. Only two, rela- tively young plants were found in association with the mound south of the Central Fire Road. It is possible at least one of these were planted years ago. It was noted that my LcL17-1, located on the slopes above the Eastern Fire Road, had only a single individual while multiple plants were noted at this site by Bramlet in 2003. Boxthorn at this location appears to be in decline. Overall, the secondary nature of the habitat in the valley floor, almost entirely less then 30 to 50 years of age, has likely significantly reduced the potential for rare plant diversity. Indeed, the two most abundant rare plants found tend to be tolerant of disturbed habitat. By their very nature, wetland plants like southwestern spiny rush, are quick colonizers as wetland habitats can be very dynamic. Southern tarplant is very disturbance tolerant, at least far more then a typical rare plant, and often thrives with mild soil disturbance as long as the disturbance does not occur while the plants are growing and blooming. In Riverside County, southern tarplant's sister species, smooth tarplant (Cen- tromadia pungens subsp. laevis), grows in very similar habitat and appears to bounce back from yearly discing quite well, as long as the soil composition is unchanged and there is adequate moisture. 28 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH Most rare plants in the region, however, are fairly sensitive to soil disturbance and often recolonize a disturbed area very slowly, on the order of decades, and only without significant competition from non-native species. We can expect that at one point, there were some very interesting species found in the lower portions of Big Canyon. However, while today the canyon has an overall wet "feel" to it, this was probably not true had a survey been con- ducted in the 1930s. Without the urban runoff currently feeding the canyons wetlands, the canyon was a decidedly an upland once away from the edges of the coastal salt marsh. 7.1 RECOMMENDATIONS There are several recommendations that can be made for future activities regarding rare plants. An early spring survey of the bluff slopes may locate additional sensitive taxa, primarily annuals, if more information is needed for these areas. While conditions were not ideal in 2015, this report supplies a reasonably good picture for the diversity and distribution of rare plants along the canyon floor. Additional surveys of the canyo floor are not likely to add very much additional data. However, southern tarplant population can be expected to be variable depending on rainfall and temperatures. Likely this report summarizes low-end status and in more favorable years, especially years with good rainfall in April and May, more plants can be expected though the distribution will still likely look similar to that of 2015. Periodic monitoring of rare and sensitive plant sites would provide useful information regarding the status of these plants, especially if large areas of the canyon undergo significant enhancement or restoration activities. Surveys conducted every three to five years would probably be sufficient. The primary recommendation is already well understood. Exotic removal along the canyon floor and on the sur- rounding slopes would significantly improve the opportunities for sensitive plants to expand or become established. Exotic removal on the slopes, especially the north slope, bounding Big Canyon should be accomplished with as little soil disturbance as possible. These are the only areas where the soils have perhaps never been seriously dis- turbed. Obviously, this is less critical for the canyon floor were most of the soils, especially in the lower canyon, are likely imported. However, naturally occurring habitats that have become established, especially wet meadow, should also be enhanced with a light touch in order to take advantage of the 10-30 years that have already gone into natural restoration. As much as possible, rare plants sites should be avoided or incorporated into restoration areas, though southwestern spiny rush maybe relatively easy to re-establish if it cannot be avoided. Southern tarplant presents a unique chal- lenge. This is a disturbance tolerant plant, at least compared to most rare plants. It is often found in areas with repeat disturbance like disked fields or along trail margins where some maintenance keeps the habitat clear from year to year. Restoration of wetland and scrubland habitats could easily eliminate tarplant habitat. It is important that future restoration proposals recognize the need for open, even lightly disturbed somewhat mesic habitats are available for southern tarplant. As well as southern tarplant has been able to manage in coastal southern California, over 30 percent of known populations are extirptated, rising to about 40 percent if just considering populations in the Los Angeles Basin region. About 50 percent of the remaining populations have clear identifiable threats. 29 RARE AND SENSITIVE PLANTS OF BIG CANYON, NEWPORT BEACH 8.0 REFERENCES CITED Baldwin, B.G., D.H. Goldman, D.J.

Photographs of the plant taken in 1999 show only several stems, the largest not exceeding one -meter as compared to the current plant with perhaps a dozen trunks, some over 2 meters tall. This suggests that the individual was planted or became estab- lished in the late 1980s or early 1990s and has persisted for at least 20 -years. At this time it appears A. decipiens is the correct name for this specimen.

The surveys were conducted in all areas of suitable habitat. For purposes of this survey, suitable CAGN habitat includes all sagebrush scrub habitat (and all sagebrush sub -associations) that occurs on site. The project site encompasses a total of approximately 88 acres with approximately 21 acres of suitable habitat for CAGN present. The surveys were conducted throughout the entire survey area including all habitats, whether they were primary constituent elements, secondary constituent elements, or non -habitat. CAGN is a federally listed threatened species and a California Department of Fish and Wildlife (CDFW) Species of Special Concern. It is closely associated with coastal sage scrub habitat, and is thereby threatened primarily by loss, degradation, and fragmentation of this habitat. CAGN typically occurs below 820 feet above mean sea level (amsl) within 22 miles of the coast and 1,640 feet amsl for inland regions (Atwood and Bolsinger 1992). Studies have suggested that CAGN avoid nesting on very steep slopes (greater than 40%) (Bontrager 1991). CAGN is also impacted by brown -headed cowbird (Molothrus ater) nest parasitism (Braden et al. 1997). LOCATION AND EXISTING CONDITIONS The project site is located in the City of Newport Beach, Orange County, California. It is situated within the lower reach of the Big Canyon Creek watershed that originates approximately 2 miles upstream to the southeast (Figures 1 and 2). The watershed draining into the project site encompasses approximately 1,200 acres (2 square miles) from its headwaters located near the San Joaquin Reservoir east of MacArthur Boulevard. Big Canyon Creek flows from southeast to WWW ouaex.Co" Recovery Permit Coordinator Subject: Focused California Gnatcatcher Survey, Big Canyon Resource and Recreation Management Plan Project, Orange County, California northwest through the 50 -acre Big Canyon Nature Park and ultimately drains into Upper Newport Bay. The project site is located in Sections 24 and 25 of Township 6S South, Range 10 West of the Newport Beach 7.5 -minute U.S. Geological Survey topographic quadrangle. Big Canyon Creek occurs within the coastal portion of the Orange County Central -Coastal Subregion Natural Community Conservation Plan/Habitat Conservation Plan, and is designated as open space (County of Orange 1996). The project site is mapped within the coastal zone and is bounded by urbanized areas, including single-family residences, roadways, and a golf course adjacent to the east portion of the project site. The project site is characterized by a flat to moderately sloping floodplain with steep northern and southern bluffs. Elevations within the project site ranges from below mean sea level at its westernmost extent, where it intercepts with the Upper Newport Bay west of Back Bay Drive, to approximately 115 feet amsl along the southern extent of the canyon. According to the U.S. Department of Agriculture (USDA 2015), soils within the project site are predominantly well -drained loams of the following series: Anaheim clay loam, 150/o-30% slopes; Anaheim clay loam, 300/o-50% slopes; Balcom clay loam, 30%-50% slopes; beaches; Calleguas clay loam, 500/o-75% slopes; Cieneba sandy loam, 30%-75% slopes; Marina loamy sand, 2%-9% slopes; Myford sandy loam thick surface, 20/6-9% slopes; San Emigdio fine sandy loam moderately fine substrate, 0%-2% slopes; Sorrento loam, 20/6-9% slopes; and tidal flats. VEGETATION COMMUNITIES Twenty-eight vegetation communities or land covers were identified on the project site. These communities include native upland communities, riparian and wetland communities, and non- native land covers or communities. Vegetation acreages are presented in Table 1, and primary constituent element habitats suitable for CAGN are described following the table.

One mapping unit within this alliance was mapped within the study area and is described in the following text. Fourwing Saltbush Disturbed Mapping Unit The fourwing saltbush disturbed mapping unit is not recognized by the Natural Communities List (CDFG 2010). This mapping unit was used to differentiate areas dominated by fourwing saltbush, but characterized by areas of disturbance. Quailbush Alliance The quailbush alliance includes quailbush (Atriplex lentiformis) as the dominant species in the shrub layer. The alliance has an open to intermittent layer that is less than 15 feet (5 meters) in height with a variable herbaceous layer (Sawyer et al. 2009). Species associated with the alliance include California sagebrush, fourwing saltbush, coyotebrush, mulefat (Baccharis salicifolia ssp. salicifolia), California brittlebush, laurel sumac (Malosma laurina), ngaio tree (Myoporum laetum), arrowweed (Pluchea sericea), lemonadeberry (Rhus integrifolia), alkali sacaton (Sporobolus airoides), woolly seablite (Suaeda taxifolia), and Tamarix spp. (Sawyer et al. 2009). METHODS Focused surveys for CAGN were performed on the project site between April 20 and May 26, 2015, by permitted Dudek Biologists Paul Lemons (Permit No. TE051248-5), and Jeff Priest (Permit No. TE840619-5.1). Non -permitted Biologists Karen Mullen, PhD, and Johanna Page 11-01 D U D E K 5 July 81 2015 Recovery Permit Coordinator Subject: Focused California Gnatcatcher Survey, Big Canyon Resource and Recreation Management Plan Project, Orange County, California accompanied both CAGN-permitted biologists as passive observers, which included sitting quietly with little or no movement for prolonged periods while studying CAGN movements with binoculars and listening carefully to vocalizations (Table 2). Only permitted biologists used audio -playback techniques to entice CAGN responses. The surveys were conducted following the currently accepted protocol of the U.S. Fish and Wildlife Service's (USFWS's) Coastal California Gnatcatcher (Polioptila californica californica) Presence/Absence Survey Protocol (USFWS 1997), using the breeding season survey methods. The survey included three visits at a minimum of 7 -day intervals. Survey routes are shown in Figure 3. Survey routes completely covered all areas of suitable CAGN habitat on site. Appropriate birding binoculars (705 to 10x50 power) were used by each permitted biologist to aid in detecting and identifying bird species. The survey conditions were within protocol limits, as shown in Table 2. A recording of vocalizations was used frequently to elicit a response from the species. The recording was played approximately every 50 to 100 feet, and when a CAGN was detected, the playing of the recording ceased to avoid harassment.

These survey efforts detected one CAGN pair primarily using the saltbush scrub in the southwest portion of the project site. Previous survey efforts also included a color -banding study of CAGN in the project site in 1991 in which several pairs of CAGN were identified (as referenced in CCI 2004). During the most recent survey, Dudek biologists observed one CAGN pair on the entire project site (Figure 3) primarily using California sagebrush scrub, fourwing saltbush scrub, and California brittlebush-California sagebrush scrub in the southwest portion of the project. The pair was also observed anecdotally in the same area during surveys for other species. A total of 51 wildlife species were observed during this survey. Species observed include 2 reptiles, 46 birds, and 3 mammals. A full list of wildlife species observed in the study area during the surveys is 11-01 D U D E K 6 July 81 2015 Recovery Permit Coordinator Subject: Focused California Gnatcatcher Survey, Big Canyon Resource and Recreation Management Plan Project, Orange County, California provided in Appendix A.

CA;LIFORMA V2024 August 12, 2015 U.S. Fish and Wildlife Service Attn: Recovery Permit Coordinator 2177 Salk Avenue, Suite 250 Carlsbad, California 92008 8811-01 Subject: 2015 Least Bell's Vireo and Southwestern Willow Flycatcher Focused Survey Results for the Big Canyon Resource and Recreation Management Plan Project, Orange County, California Dear Recovery Permit Coordinator: This report documents the results of eight protocol -level presence/absence surveys for the state - and federally listed endangered least Bell's Vireo (Vireo belhi pusillus; vireo) and the state- and federally listed endangered southwestern willow flycatcher (Empidonax trailhi extimus; flycatcher). These focused surveys were conducted within the Big Canyon Resource and Recreation Management Plan Project (project). The surveys were conducted in all areas of suitable vireo and flycatcher habitat throughout the entire survey area. The southwestern willow flycatcher and least Bell's vireo are closely associated with riparian habitats, especially densely vegetated willow scrub and riparian forest vegetation. These species are threatened primarily by loss, degradation, and fragmentation of riparian habitats. They also are impacted by brown -headed cowbird (Molothrus ater) nest parasitism. LOCATION AND EXISTING CONDITIONS The project site is located in the City of Newport Beach, Orange County, California. It is situated within the lower reach of the Big Canyon Creek watershed that originates approximately 2 miles upstream to the southeast (Figures 1 and 2). The watershed draining into the project site encompasses approximately 1,200 acres (2 square miles) from its headwaters located near the San Joaquin Reservoir east of MacArthur Boulevard. Big Canyon Creek flows from southeast to northwest through the 50 -acre Big Canyon Nature Park and ultimately drains into Upper Newport Bay. The project site is located in Sections 24 and 25 of Township 6S South, Range 10 West of the Newport Beach 7.5 -minute U.S. Geological Survey topographic quadrangle. Big Canyon Creek occurs within the coastal portion of the Orange County Central -Coastal Subregion Natural Community Conservation Plan/Habitat Conservation Plan, and is designated as open space (County of Orange 1996). The project site is mapped within the coastal zone and is www uuM-COM Recovery Permit Coordinator Subject: 2015 Least Bell's Vireo and Southwestern Willow Flycatcher Focused Survey Results for the Big Canyon Resource and Recreation Management Plan Project, Orange County, California bounded by urbanized areas, including single-family residences, roadways, and a golf course adjacent to the east portion of the project site. The project site is characterized by a flat to moderately sloping floodplain with steep northern and southern bluffs. Elevations within the project site ranges from below mean sea level at its westernmost extent, where it intercepts with the Upper Newport Bay west of Back Bay Drive, to approximately 115 feet amsl along the southern extent of the canyon. According to the U.S. Department of Agriculture (USDA 2015), soils within the project site are predominantly well -drained loams of the following series: Anaheim clay loam, 15%-30% slopes; Anaheim clay loam, 30%-50% slopes; Balcom clay loam, 30%-50% slopes; beaches; Calleguas clay loam, 50%-75% slopes; Cieneba sandy loam, 30%-75% slopes; Marina loamy sand, 21/o-9% slopes; Myford sandy loam thick surface, 2%-9% slopes; San Emigdio fine sandy loam moderately fine substrate, 0%-2% slopes; Sorrento loam, 2%-9% slopes; and tidal flats. VEGETATION COMMUNITIES Twenty-eight vegetation communities or land covers were identified on the project site. These communities include native upland communities, riparian and wetland communities, and non- native land covers or communities. Vegetation acreages are presented in Table 1, and primary constituent element habitats suitable for vireo and flycatcher are described following the table.

For this particular site, the Ornamental Landscaping Mapping Unit consists of pepper trees (Schinus molle, S. terebinthifolius) and myoporum (Myoporum laetum) that dominate or co -dominate the tree canopy within Big Canyon. Although this is typically not considered suitable flycatcher or vireo habitat, the tree layer forms an open to intermittent canopy with an understory of shrubs along the creek within Big Canyon, therefore these areas were also surveyed. 8811-01 D U D E K 3 August 2015 Recovery Permit Coordinator Subject: 2015 Least Bell's Vireo and Southwestern Willow Flycatcher Focused Survey Results for the Big Canyon Resource and Recreation Management Plan Project, Orange County, California Arroyo Willow Thickets Alliance The arroyo willow thickets alliance (Salix lasiolepis thickets alliance) includes arroyo willow (Salix lasiolepis) as the dominant or co -dominant tree in the canopy. The alliance has an open to continuous tree canopy less than 65 feet (20 meters) in height with an open to intermittent shrub canopy and a variable ground layer (Sawyer et al. 2009). Species associated with the alliance include white alder (Alnus rhombifolia), coyote brush, mulefat (Baccharis salicifolia), California sycamore (Platanus racemosa), Fremont cottonwood (Populus fremontii), blue elderberry, and other willows (Sawyer et al. 2009). One mapping unit within this alliance was mapped within the study area and described below: arroyo willow disturbed mapping unit. Arroyo Willow Disturbed Mapping Unit The arroyo willow disturbance mapping unit is not recognized by the Natural Communities List (CDFG 2010). This mapping unit was used to differentiate areas dominated by arroyo willow, but characterized by areas of disturbance. METHODS Suitable habitat areas within the project study area were surveyed eight times for vireo and five times for flycatcher (Table 2). Permitted Dudek wildlife biologists Jeff D. Priest (JDP; Permit #TE840619) and Paul M. Lemons (PML; Permit #TE051248) conducted all combined flycatcher/vireo surveys, while qualified Dudek biologists Karen Mullen, PhD, Johanna Page, and Ryan Henry conducted vireo surveys on some visits (Table 2). Only permitted biologists JDP and PML used audio -playback techniques to elicit flycatcher responses. Focused surveys for these species were initiated on April 20, 2015, and continued through July 15, 2015.

This route was arranged to cover all suitable habitat on site (depicted on Figure 3). A vegetation map (1:2,400 scale; 1 inch=200 feet) of the project site was available to record any detected vireo or flycatcher. Binoculars (7X50, 10X42, 10X50) were used to aid in detecting and identifying wildlife species. The five surveys conducted for flycatcher followed the currently accepted protocol (A Natural History Summary and Survey Protocol for the Southwestern Willow Flycatcher [Sogge et al. 2010]), which states that a minimum of five survey visits is needed to evaluate project effects on flycatchers. It is recommended that one survey is made between May 15 and 31, two surveys between June 1 and June 24, and two surveys between June 25 and July 17. Surveys during the final period (June 25 and July 17) were separated by at least five days. A tape of recorded flycatcher vocalizations was used, approximately every 50 to 100 feet within suitable habitat, to induce flycatcher responses. If a flycatcher had been detected, playing of the tape would have ceased to avoid harassment. A Section 10(a)(1)(A) permit is not required to conduct presence/absence surveys for vireo. The eight surveys for vireo followed the currently accepted Least Bell's Vireo Survey Guidelines (USFWS, 2001), which states that a minimum of eight survey visits should be made to all riparian areas and any other potential vireo habitats between April 10 and July 31. The site visits are required to be conducted at least 10 days apart to maximize the detection of early and late arrivals, females, non -vocal birds, and nesting pairs. Taped playback of vireo vocalizations were not used during the surveys. Surveys were conducted between dawn and noon and were not conducted during periods of excessive or abnormal cold, heat, wind, rain, or other inclement weather. Weather conditions, time of day, and season were appropriate for the detection of flycatcher and vireo (Table 2). 8811-01 D U D E K 5 August 2015 Recovery Permit Coordinator Subject: 2015 Least Bell's Vireo and Southwestern Willow Flycatcher Focused Survey Results for the Big Canyon Resource and Recreation Management Plan Project, Orange County, California RESULTS No flycatchers or vireo were observed during the focused surveys.

This MMRP lists all applicable mitigation measures from the Final Initial Study and Mitigated Negative Declaration (IS/MND). The appropriate timing of implementation and responsible party are identified to ensure proper enforcement of the mitigation measures from the Final IS/MND to reduce project impacts to less than significant levels. 6-129 Project Description The proposed project is located within the City of Newport Beach, on a site in the eastern portion of the 60 -acre Big Canyon Nature Park. The proposed project encompasses 6 acres and includes the following: (1) restore historic riparian habitat by removing non-native vegetation and replace it with native plantings, (2) stabilize the creek and floodplain, (3) improve water quality in Big Canyon Creek and Newport Bay through the addition of a water quality treatment bioretention cell, extension of the Jamboree culvert, concrete stilling basin, and dosing station, and (4) enhance public access within the Big Canyon Nature Park. The project also includes maintenance of the proposed water quality features to ensure that the features are functioning as originally designed. 6-130 Mitigation Monitoring and Reporting Program The following table will be used by the City of Newport Beach to enforce mitigation measures during each phase of the project pursuant to Section 15097 of the State CEQA Statues and Guidelines and Public Resources Code Section 21081.6. The City of Newport Beach will be responsible for the implementation for all the mitigation measures listed in Table 1 below and shall maintain monitoring documentation on each measure within the City of Newport Beach files at the addressed listed below. The entity responsible for monitoring will change based on the specific requirements identified in each mitigation measure. The timing of the implementation is also listed. When compliance with a mitigation measure for each project phase has been demonstrated, documentation on the verification date column is provided and monitoring of the measure will be deemed to be satisfied. No further monitoring will be required for the completed mitigation measure. For measures that require monitoring during operation of the project, annual documentation on the verification date column or a separate letter/memorandum shall be provided in the monitoring file that is kept at the City of Newport Beach. The Mitigation Monitoring and Reporting Program will be kept on file at the following address: City of Newport Beach, Public Works Department 100 Civic Center Drive Newport Beach, CA 92660 6-131 TABLE 1 MITIGATION MONITORING AND REPORTING PROGRAM Mitigation Measure Timing for Responsible Party Verification Date Implementation Biological Resources (BIO) 13I0-1: Nesting Birds. Impacts to nesting birds would be avoided by conducting all Prior to construction Public Works Department grading and construction activities outside of the bird breeding season (February 15— Grading and construction and Project Biologist August 31). If breeding season cannot be avoided, the following measures would be activities should be followed. conducted September 1— a. During the avian breeding season, a qualified Project Biologist shall conduct a February 14 (outside of preconstruction avian nesting survey no more than 3 days prior to vegetation bird breeding season) to disturbance or site clearing. If grading or other construction activity begins in the avoid impacts to nesting non -breeding season and proceeds continuously into the breeding season, no birds. surveys shall be required. However, if there is a break of 3 days or more in grading If unavoidable, or construction activities during the breeding season, a new nesting bird survey preconstruction survey shall be conducted before these activities begin again. shall be conducted no b. The nest survey shall cover all reasonably potential nesting locations on and within more than 3 days prior to 300 feet of the proposed construction activities areas. vegetation disturbance or c. If an active nest is found during an avian nest survey, a qualified Project Biologist site clearing. shall implement a 300 -foot minimum avoidance buffer for coastal California gnatcatcher, least Bell's vireo, and other passerine birds and a 500 -foot minimum avoidance buffer for all raptor species. Buffer distances for other species would be determined by the Project Biologist based on the species and its breeding or nesting requirements. The nest site area shall not be disturbed until the nest becomes inactive or the young have fledged. During clearing, grubbing, and excavation activities, the nest will be monitored by a qualified biologist for the duration of these activities, or until the nestlings have fledged. Daily monitoring may be required; however, the frequency of nest monitoring will be determined by the biologist based on the species and level of activity in the project area. 13I0-2: Vegetation Communities. The project would impact a total of 2.46 acres of Prior to construction Public Works Department southern riparian forest, and 0.50 acre of coastal sage scrub. These vegetation communities are both highly disturbed from a heavy infestation of non-native plants and compacted, saline soils. These low -quality habitats would be restored to provide habitats with much greater ecological function than the current conditions. A total of 2.46 acres of southern riparian forest would be mitigated onsite through substantial habitat restoration (2.03 acres), willow riparian forest habitat creation (0.25 acre), and riparian habitat enhancement (0.64 acre). Impacts to coastal sage scrub would be mitigated onsite through restoration of 1.85 acres, which is 1.35 acres in excess of the required 1:1 ratio. Impacts to non-native grassland, disturbed areas, and ornamental vegetation do not require mitigation (Table 3-5). 6-132 Mitigation Measure Timing for Responsible Party Verification Date Implementation TABLE 3-5 MITIGATION FOR IMPACTS TO VEGETATION COMMUNITIES Required Actual Plant Communities and Land Cover Impacts Mitigation Mitigation Excess Types (Acres)' (1:1 ratio) (Acres) (Acres) Southern Riparian Forest (SRF )2 2.46 2.46 2.923 +0.46 Coastal Sage Scrub (CSS) 0.50 0.50 1.85 +1.35 Non -Native Grassland (NNG) 1.20 0.00 0.00 0.00 Disturbed (Existing Roads & Trails) 0.13 0.00 0.00 0.00 Ornamental (ORN) 0.06 0.00 0.00 0.00 Total Acreage of Impacts 4.35 2.96 4.53 +1.81 Includes permanent impacts, temporary impacts associated with habitat restoration component, and temporary impacts associated with construction of water quality facilities and infrastructure. 2 Note that some portions of the existing southern riparian forest habitat are not considered jurisdictional by the Corps/RWQB and/or CDFW; therefore, refer to Table 5 for detailed impact acreages of jurisdictional resources. 3 Includes 2.03 acres of substantial restoration, 0.25 acre of habitat creation, and 0.64 acre of habitat enhancement. SOURCE: ESA, 2016 In addition, as part of the Habitat Restoration Plan, construction and operational Best Management Practices (BMPs) will be implemented to protect trees within the riparian habitat from the Polyphagous shot hole borer (PSHB). PSHB is a new insect pest in southern California that drills into trees and carries in a symbiotic fungus, which infests and kills the tree (UCR, Center for Invasive Research 2016). The nearest known infestation is 1 mile east of the project site. This invasive species is potentially devastating to native riparian habitat, as it can attack a variety of native tree species, such as Coast Live Oak (Quercus agrifolia), California sycamore (Platanus racemosa), Fremont cottonwood (Populus fremontii), red willow (Salix laevigata), and white alder (Alnus rhambifolia). PSHB attacks a variety of non-native species as well; however, there are no reported incidences of PSHB invading the Brazilian peppertree. In order to ensure that project activities do not result in the spread of PSHB into the project site, the following Best Management Practices will be employed: 1. During the tailgate training prior to construction, the onsite workers will be 6-133 Mitigation Measure Timing for Implementation Responsible Party Verification Date educated about PSHB and its spread; 2. Prior to Peppertree removal, the project area will be surveyed for signs of PSMH; if potential signs are observed, the University of California Cooperative Extension in Orange County (UCCE) and/or University of California, Riverside Eskalen Lab will be notified for confirmation (UCREL). 3. Should PSHB be found in any material that will be cleared and grubbed, the material shall be chipped to <1" and disposed of in an approved landfill. Other remediation actions will be discussed with UCCE or UCREL. 4. To reduce the spread of the beetle or fungus, all equipment will be disinfected prior to coming onsite. 13I0-3: Jurisdictional Wetlands. As stated previously, the project has been designed to During construction Public Works Department avoid and minimize impacts to jurisdictional resources and high-quality habitat to the extent practicable. To mitigate for unavoidable permanent impacts to Waters of the United States/State, both habitat creation and enhancement activities would be conducted onsite, as summarized in Table 3-8. TABLE 3-8 MITIGATION FOR PERMANENT IMPACTS TO JURISDICTIONAL AREAS Permanent Impacts Mitigation for Jurisdictional Habitat Types (acres) Impacts Corps/RWQCB Non-Wetlands/CDFW 0.24 0.25 acre of riparian forest habitat Riparian/CCC Wetland creation (1:1 mitigation ratio)1 CDFW Riparian only 0.19 0.64 acre of habitat enhancement CCC Wetland only 0.33 (extensive invasive species removal) Fullfills Corps "no net loss" requirement. SOURCE: ESA, 2015 To offset for permanent losses to 0.24 acre of non -wetland waters of the United States (Corps/RWQCB), 0.44 acre of CDFW and 0.57 acre of CCC jurisdictional wetlands, the creation of 0.25 acre of new habitat is proposed directly to the southwest of the proposed bioretention cell. This would satisfy the federal mandate for no net loss of wetlands by the Corps. The deficit acreage (0.19 acre for CDFW and 0.33 acre for CCC) would be satisfied through the removal of non-native vegetation in adjacent riparian and seed source areas (i.e., riparian habitat enhancement). This would include removal of the Brazilian peppertrees both east of Jamboree Road and on the north slopes of the canyon west of Jamboree Road that are the primary source of invasive 6-134 Mitigation Measure Timing for Implementation Responsible Party Verification Date seeds for Big Canyon. In addition, understory invasives not mapped by Dudek, including During construction; and Qualified pampas grass, periwinkle, and English ivy, are prevalent throughout the project area. Archaeologist These species would be removed as part of the enhancement activities. Approximately 0.64 acre of invasive removal of the 1.07 acres available would be considered mitigation for unavoidable permanent impacts. Enhancement activities are distinguished from the restoration activities proposed (not mitigation) in that restoration would require grading and extensive soil remediation to achieve full habitat functioning, and enhancement areas would not. Jurisdictional areas temporarily impacted as a result of construction of the water quality or infrastructure -related components of the project would be restored to native habitat at a 1:1 ratio. A full Habitat Restoration Plan describing the Big Canyon restoration as well as habitat mitigation activities would be submitted for review and approval as part of the environmental permitting process. Cultural Resources (CR) CR -1: Archaeological Monitoring. An archaeological monitor (working under the direct Prior to construction; Public Works Department supervision of a Secretary of the Interior -qualified archaeologist [USDI 2008]) shall be During construction; and Qualified retained to observe all ground -disturbing activities, including but not limited to brush Archaeologist clearance, vegetation removal, grubbing, grading, and excavation. Prior to start of ground -disturbing activities, the archaeologist shall conduct cultural resources sensitivity training for all construction personnel. Construction personnel shall be informed of the types of archaeological resources that may be encountered, and of the proper procedures to be enacted in the event of an inadvertent discovery of archaeological resources or human remains. The City shall ensure that construction personnel are made available for and attend the training and retain documentation demonstrating attendance. Archaeological monitoring shall be conducted by an archaeologist familiar with the types of archaeological resources that could be encountered within the project site. The qualified archaeologist, in coordination with the City, may reduce or discontinue monitoring if it is determined that the possibility of encountering buried archaeological deposits is low based on observations of soil stratigraphy or other factors. The archaeological monitor shall be empowered to halt or redirect ground -disturbing activities away from the vicinity of a discovery until the qualified archaeologist has evaluated the discovery and determined appropriate treatment. The archaeological monitor shall keep daily logs detailing the types of activities and soils observed, and any discoveries. After monitoring has been completed, the qualified archaeologist shall prepare a monitoring report that details the results of monitoring. The report shall be submitted to the City, the Corps, and any Native American groups who request a copy. A copy of the final report shall be filed at the SCCIC. If archaeological resources are encountered during monitoring, and if it is determined that the discovered archaeological resource constitutes a historic property under 6-135 Mitigation Measure Timing for Implementation Responsible Party Verification Date Section 106 of the NHPA or a historical resource under CEQA, avoidance and preservation in place is the preferred manner of treatment. Preservation in place maintains the important relationship between artifacts and their archaeological context and also serves to avoid conflict with traditional and religious values of groups who may ascribe meaning to the resource. Preservation in place may be accomplished by, but is not limited to, avoidance, incorporating the resource into open space, capping, or deeding the site into a permanent conservation easement. In the event that preservation in place is demonstrated to be infeasible and data recovery through excavation is the only feasible mitigation available, a Cultural Resources Treatment Plan would be prepared and implemented by a qualified archaeologist in consultation with the Corps and the City. The plan will provide for the adequate recovery of the scientifically consequential information contained in the archaeological resource. The Corps and the City shall be required to consult with appropriate Native American representatives in determining treatment for prehistoric or Native American resources to ensure cultural values ascribed to the resource, beyond that which is scientifically important, are considered. CR -2: Native American Monitoring. The City shall retain a Native American monitor to Prior and during Public Works Department observe all ground -disturbing activities, including but not limited to brush clearance, construction and Native American vegetation removal, grubbing, grading, and excavation. The Native American monitor Monitor shall be selected from amongst the Native American groups identified by the NAHC as having affiliation with the project area. The Native American representative shall be allowed to participate in the cultural resources sensitivity training, discusses in Mitigation Measure CR -1, and all authorities ascribed to the archaeological monitor, including the authority to stop work in the event of the discovery of cultural resources, shall also apply to the Native American monitor. In the event that archaeological materials are encountered, the Native American monitor shall participate in any discussions involving treatment and subsequent mitigation. CR -3: Paleontological Monitoring. A qualified paleontologist meeting the Society for During construction Public Works Department Vertebrate Paleontology (SVP) guidelines for professional paleontologist (SVP, 2010) and Qualified shall be retained to oversee all mitigation measures related to paleontological Paleontologist resources. That said, both the paleontological and archaeological monitoring could be carried out by the same person, presuming the monitor is qualified in both disciplines. During ground disturbing activity, the qualified paleontologist or paleontological monitor shall conduct spot-checks of exposed sediments. The purpose would be to determine whether the project would impact the paleontologically sensitive Monterey Formation. The qualified paleontologist may institute paleontological monitoring if, based on observations of subsurface stratigraphy or other factors, he or she determines that the possibility of encountering fossiliferous deposits is high. Paleontological monitoring would be conducted by a paleontological monitor working under the supervision of the qualified paleontologist. In the event that monitoring is required, the monitor shall have the authority to temporarily halt or divert work away from exposed fossils in order to 6-136 Mitigation Measure Timing for Implementation Responsible Party Verification Date recover the fossil specimens and shall complete daily monitoring logs outlining the day's and Construction activities. The qualified paleontologist shall prepare a final monitoring report to be Contractor submitted to the City and filed with the local repository, along with any fossils recovered During construction Public Works Department during construction. and Construction The qualified paleontologist shall also contribute to any construction worker cultural Contractor resources sensitivity training (see Mitigation Measure CR -1) either in person or via a During construction Public Works Department training module provided to the qualified archaeologist. The training shall include and Construction information of the types of paleontological resources that may be encountered, and the Contractor proper procedures to be enacted in the event of an inadvertent discovery of During construction Public Works Department paleontological resources. and Construction In the event of unanticipated discovery of paleontological resources, the City shall Contractor cease ground -disturbing activities within 100 feet of the find until it can be assessed by During construction Public Works Department the qualified paleontologist. The qualified paleontologist shall assess the find, and Construction implement recovery measures if necessary, and determine if paleontological monitoring Contractor is warranted once work resumes. Noise (NOI) NOI-1: Large construction equipment, such as large bulldozer and loaded trucks, shall During construction Public Works Department be replaced with smaller equipment when the construction equipment is within 45 feet of and Construction the residential structure. Contractor NOI-2: The construction contractor shall ensure proper maintenance and working order During construction Public Works Department of equipment and vehicles and that all construction equipment is equipped with and Construction manufacturers approved mufflers and baffles.

The City of Newport Beach (City) requested comments on the MND by April 4, 2016. The following statements and comments have been prepared pursuant to the Department's authority as Trustee Agency with jurisdiction over natural resources affected by the project (California Environmental Quality Act [CEQA] Guidelines § 15386) and pursuant to our authority as a Responsible Agency under CEQA Guidelines section 15381 over those aspects of the proposed project that come under the purview of the California Endangered Species Act (CESA; Fish and Game Code § 2050 et seq.) and Fish and Game Code section 1600 et seq. The Department also administers the Natural Community Conservation Planning (NCCP) program. The City is a participating landowner under the Central/Coastal Orange County NCCP/Habitat Conservation Plan (HCP). Additionally, the Department owns and manages the Upper Newport Bay Ecological Reserve (UNBER). The City has deliberated restoration efforts within Big Canyon for more than 10 years and various Department staff have been involved in previous planning efforts. Currently the City has funding for Phases IA and IB, the proposed project. As more funding becomes available, it is anticipated that Phase I will precede potential future restoration efforts in the remaining downstream areas of the watershed. The proposed project site -is located on a 10 -acre site within the eastern portion of the 60 -acre Big Canyon Nature Park, including a portion of Big Canyon Creek, east of Upper Newport Bay, adjacent to Jamboree Road. Big Canyon is the only natural, undeveloped portion of the Big Canyon Watershed and the only significant remaining natural canyon on the east side of Newport Bay. Directly downstream of the project area, the lower 15 -acre portion of Big Canyon Nature Park is part of the UNBER. Big Canyon Nature Park is located in the Upper Newport Bay State Marine Conservation Area and is part of southern California's coastal estuarine environment. In addition, Newport Bay discharges adjacent to the Newport Coast Area of Special Biological Significance. On-site land uses of the project site include utilization of the multipurpose trail/access road that runs through the site, as well as maintenance activities associated with storm drain facilities. Conserving Caffornia's WifdCfe Since 1870 6-139 Mr. Robert Stein City of Newport Beach Public Works Department April 4, 2016 Page 2 of 6 Project activities in Phases IA and IB, include creek restoration/stabilization, riparian habitat creation and enhancement, installation of a stormwater water quality treatment bioretention cell, implementation of dry weather water quality selenium reduction measures, infrastructure improvements including the extension and improvement of the existing access roads, a public trail along the toe of slope along the west side of Jamboree Road, and the installation of an 8 - foot wide bicycle path connector that will provide access directly from Jamboree Road. Topographically, the project site is characterized by steeply sloping bluffs and a narrow, moderately sloped floodplain. Habitat types present on site include southern riparian forest (4.00 acres), coastal sage scrub (1.53 acres), non-native grassland (2.83 acres), ornamental (0.78 acre), disturbed areas/roads (0.40 acre), and alkali meadow (0.10 acre); non -natives occur prolifically throughout the site in all habitat types. The draft MND states that, based on the California Natural Diversity Data Base, Big Canyon Creek Historic Tidal Wetlands Conceptual Restoration Plan Upper Newport Bay (CCI 2004), Big Canyon Creek Restoration Project Phase II Feasibility Study (WRA 2007), and biological surveys conducted by Environmental Science Associates (ESA) in early spring 2015, no NCCPIHCP covered species are located within the project area. However, three California Species of Special Concern were observed on site within the riparian forest habitat, including Cooper's hawk (Accipiter cooperii), yellow -breasted chat (Icteria virens), and yellow warbler (Setophaga petechial). The Department offers the following comments and recommendations to assist the City in avoiding or minimizing potential project impacts on biological resources. Proposed Project Phase IA and IiB The draft MND's Project Description states, "The proposed project is currently being planned in coordination with a Resources and Recreation Management Plan (RRMP) being prepared by the Irvine Ranch Conservancy under contract with the City of Newport Beach for the Big Canyon Nature Park" (page 2-1). In order to ensure that the RRMP is in compliance with the NCCP/HCP as stated, we request that the Department and United States Fish and Wildlife Service be included in the development and review of the RRMP. 2. The draft MND does not include an analysis of what vegetation types would be established and persist, given that a portion of the surface flow will be captured (i.e., removed from this portion of the riparian system) and routed directly to a water treatment basin. The final MND should include a detailed discussion concerning anticipated vegetation types in relationship to change in surface water flow, including whether or not the impacts of changed surface flow on vegetation types are significant without mitigation. 3. The Department is aware that least Bell's vireo (Vireo bellii pusillus), a conditionally covered species under the NCCPIHCP, have been seen within the project area in 2014 and 2015 and may be supported by the site. Mitigation Measure BIO -1 partially addresses impacts to nesting birds; however, because of the sensitive nature of the habitat, the potential for least Bell's vireo to occur, and the project site's proximity to other conserved open space, we recommend amendments be made to this measure to include the following: a. Clearing, grubbing, or/and excavation activities in potentially suitable nesting habitat is not allowed during the nesting season for least Bell's vireo (March 15 -August 31). If these activities will occur during that time frame, the Department recommends the 6-140 Mr. Robert Stein City of Newport Beach Public Works Department April 4, 2016 Page 3 of 6 project proponent seek appropriate take authorization under CESA prior to implementing the project, Appropriate authorization may include an incidental take permit (ITP) or a consistency determination in certain circumstances (Fish and Game Code §§ 2080.1, 2081, subds. (b), (c)). Therefore, BIO -1 should be amended to specify the potential notification requirements under:CESA; b. we request that protocol surveys for least Bell's vireo, along with any other reports and maps of significant impacts to native vegetation/foraging habitat be shared with the Department; c. that a daily monitor be present on site should construction continue into the nesting bird season; and, d• the Department recommends that nesting surveys described be conducted no later than three (3) days prior to construction. Longer periods between nesting surveys and the start of construction activities increase the likelihood that nesting activity can occur undetected, which may increase direct impacts to special status. and passerine species such that they are significant without further mitigation. 4. The draft MND states that the areas defined with the current jurisdictional delineation report. will be regulated pursuant to Section 1600. et seq. of the Fish and Game Code.(pages 3-23). The mitigation ratios and acreages referenced to offset temporary and permanent: impacts stated in Mitigation Measures BIO -2 and 13I0-3 may not be adequate to satisfy obligations under the Project's Streambed Alteration Agreement. Based on habitat•type and quality, the Department will evaluate the adequacy of ratios at the time the project applicant formally submits a streambed notification package to the Lake and Streambed Alteration Program of the Department. 5. Mitigation Measure 610-3 proposes the preparation and implementation of a mitigation plan which would restore areas temporarily impacted by construction activities and subsequently mitigate permanent impacts (page 3-23). The mitigation measure does not state who will be implementing this plan, when the measures would be implemented, or how the mitigation would be approved and conducted. The mitigation measure should include monitoring and reporting on the effectiveness of the measure at compensating project disturbance that may result in permanent habitat conversion to non-native plant habitat. Additionally, for the purposes of review under CEQA, the finai MAID should include revisions to include a designated representative at the City or their designee to oversee restoration, commitment to a`timeframe to when mitigation would occur, and the proposed mitigation plan. 6. The environmental analysis does not clearly define whether noise generated during project activities was considered as a potential significant impact to biological resources, particularly with regard to avian species. Generally, average hourly noise levels above 60 decibels are considered to negatively impact nesting birds and other wildlife. The final MND should fully describe BMPs (i.e., barriers/walls, sound muffling devices on mechanized equipment, etc.) that would be implemented to attenuate project -related construction and operational noise levels in excess of ambient levels. Setbacks should be established at the edge of sensitive habitats on and off site to avoid or minimize noise -related impacts on wildlife, particularly avian species. In addition to evaluating potential direct impacts, a more detailed discussion of indirect impacts to biological resources from noise resulting from the proposed project should be analyzed in the final MND. 6-141 Mr. Robert Stein City of Newport Beach Public Works Department April 4, 2016 Page 4 of 6 7. Polyphagous Shot Hole Borer (PSHB) is an invasive beetle that carries three fungi: Fusarium euwallaceae, Graphium euwallaceae, and Paracremonium pembeum. The adult female (1.8-2.5 mm long) tunnels galleries into the cambium of a wide variety of host trees, where it lays its eggs and propagates the fungi species (above) for the express purpose of feeding its young. These fungi cause Fusarium Dieback disease_, which interrupts the transport of water and nutrients in at least 38 tree species. With documented occurrences throughout Southern California, including the San Diego Creek drainage (University of California, Riverside (UCR); http:/leskalenlab.ucr.edu/distribution.htm1), the spread of PSHB could have significant impacts in Orange County ecosystems, specifically for those under analysis in the draft MND (e.g, riparian habitat). Therefore, with regard to PSHB, we recommend the final MND include the following: a. A thorough discussion of the direct, indirect, and cumulative impacts that could occur from the potential spread of PSHB as a result of project activities; b. an analysis of the likelihood of the spread of PSHB as a result of the invasive species' proximity to above referenced activities; c. figures within the MND and Biological Resources and Technical Report should depict potentially sensitive or susceptible vegetation communities within the project area, the known occurrences of PSHB within the project area, and PSHB's proximity to above referenced activities; and d. a mitigation measure or measure(s) within the final MND that describe Best Management Practices (BMPs) which bring impacts of the project on the spread of PSHB below a level of significance. Examples of such BMPs include: i. education of on-site workers regarding PSHB and its spread; ii. reporting sign of PSHB infestation, including sugary exudate ("weeping") on trunks or branches and PSHB entry/exit-holes (about the size of the tip of a ballpoint pen), to the Wildlife Agencies and UCR's Eskalen Lab; iii, equipment disinfection; iv. pruning in infested areas where project activities may occur; v.. avoidance and minimization of transport of potential host tree materials; vi. chipping potential host materials to less than one inch (1"<), prior to securely delivering to a landfill; vii, chipping potential host materials to less than one inch (1"<), prior to composting on- site; viii. solarization of cut logs; and/or ix. burning of potential host tree materials; and x. reporting suspected infestations to the Eskalen Lab at UC Riverside (eskalenlab. ucr.edu). Please refer to UCR's Eskalen lab website for more information regarding PSHB: http://eskalenlab.ucr.edu/avocado.htm1. . 6-142 Mr. Robert Stein City of Newport Beach Public Works Department April 4, 2016 Page 5 of 6 Potential Future Restoration Efforts 8. While the Department supports habitat restoration and water quality improvements within Big Canyon, we are concerned that the future project phases may directly and/or cumulatively impact Department property and the larger Big Canyon Watershed. While the draft MND discusses and analyzes activities assodated.with Phases IA and IB, there is also mention of future restoration efforts (page 2-3). The Biological Resources Technical Report prepared by ESA in 2016 (Appendix C) references prior Big Canyon Restoration project documents, including Big Canyon Creek Historic Tidal Wetlands Conceptual Restoration Plan Upper Newport Bay (CCI 2004) and Big Canyon Creek Restoration Project Phase 1I Feasibility Study (WRA 2007). The Pre -Construction Riverine Califarma Rapid Assessment Method (CRAM) Report, prepared by ESA (December 30, 2015, and found in Appendix B in Appendix C described above) states (page 3), "The Project is part of a larger proposed multi -phased Big Canyon Watershed Restoration and Coastal Adaption Project (Phases I and II) that has been planned -for- over a decade." It further states, "Phase I, the current Project, includes the implementation of a creek and riparian habitat restoration, stormwater treatment wetland, dry weather flow diversions, culvert improvements, and .trail planning in the upper portion of the Big Canyon Nature Preserve. Phase IIA is also pert of the current Project and continues to build on the benefits to be achieved through Phase I". The Department issued a letter to the City dated June 9, 2008, stating that we did not concur with the 2007 Big Canyon Restoration Project, citing impacts to salt marsh bird's beak (Chloropyron maritimum) and the net loss of fresh water marsh habitat. Accordingly, the Department questions whether the City has amended or altered the overall objective, scope, or proposed execution of the Big Canyon Restoration project from the 2007 Big Canyon Restoration project and the plans the Department reviewed in 2008. The Department recommends that the final MND specifically state that potential future restoration efforts and/or additional phases will undergo independent CEQA review. Additionally, we offer the following comments regarding the above -referenced potential future restoration efforts: a. The Department does not concur with any realignment of Back. Bay Drive, nor with any Big Canyon restoration activities which may take Department land; b. we do not agree that converting fresh water ponds into marsh habitat will remediate issues with selenium; to the contrary, converting selenium -laden sediment areas to fresh water marsh habitat potentially exposes the sensitive species that would utilize such habitats to selenium bio -accumulation, such as light-footed Ridgway's rail (Rallus obsoletus levipes; formerly light-footed clapper rail); and c. instead, the Department recommends that the threat of bio -accumulation of selenium, protection of sensitive species, flood control, and vector control could be more effectively achieved through the conversion of fresh water ponds to riparian habitat. Should such actions be considered in future phases, we recommend that these issues are directly analyzed and discussed to ensure that impacts are considered less than significant under CEQA. We appreciate the opportunity to comment on the draft MND for 6-143 Mr. Robert Stein City of Newport Beach Public Works Department April 4, 2016 Page 6 of 6 this project and to assist the City in further minimizing and mitigating project impacts to biological resources. The Department requests an opportunity to review and comment on any response that the City has to our comments and to receive notification of the forthcoming hearing date for the project (CEQA Guidelines; §15073(e)).
