In accordance with provisions within the Traffic Phasing Ordinance (TPO), the project includes a Traffic Study. Staff recommends that the Planning Commission recommend approval of Planned Community Amendment No. 2005 -001 and Traffic Study No. 2005 -004 to the City Council subject to the findings and conditions of approval included within the attached draft resolution. DISCUSSION The applicant plans the construction of a two -story office building consisting of 42,012 gross square feet within Corporate Plaza West. Corporate Plaza West is developed with three office buildings totaling 118,107 gross square feet. The specific location for the proposed building is near the northeast corner of East Coast Highway and Club House Drive and is currently a vacant pad, parking lot and landscaping for the adjacent office buildings. Corporate Plaza West is designated for 115,000 square feet of floor area for office development and the proposed project would bring the total floor area to 160,119 gross square feet. In order to accomplish this, the applicant is proposing to transfer Corporate Plaza West November 17, 2005 Page 2 45,119 square feet of un-built retail area from Fashion Island to accommodate the proposed construction. 4 Corporate Plaza West, Phase 2 City of Newport Beach N 0 500 1.000 Corporate Plaza West November 17, 2005 Page 3 Analysis Both planned communities are located within Statistical Area L1 (Newport Center) of the Land Use Element of the General Plan. The proposed transfer does not require a General Plan Amendment as the Land Use Element of the General Plan for Newport Center (Statistical Area L1) states the following: "Transfers of Development Rights in Newport Center are permitted, subject to approval of the City with the finding that the transfer is consistent with the intent of the General Plan and that the transfer will not result in any adverse traffic impacts." (Land Use Element, Page 77). Land Use Implementation of such a transfer is accomplished by amending both Planned Community District Regulations by increasing the allocation of the recipient site (Corporate Plaza West) and decreasing the donor site (Fashion Island). Staff has recently conducted a comprehensive review of records and found that, Corporate Plaza West is developed with 118,107 gross square feet office uses (3,107 square feet over the maximum) and Fashion Island has roughly 300,000 square feet of retail area that is yet to be constructed at this time. Corporate Plaza West is allocated a maximum of 115,000 square feet of professional office use and would require 45,119 gross square feet of additional floor area to permit the 42,012 square foot building. The site is designated Administrative, Professional & Financial Commercial. Construction of additional professional office area is consistent with this designation. Fashion Island is allocated just over 1.6 million square feet of floor area for regional retail uses and theater seating. Fashion Island is designated Retail & Service Commercial and the City would need to determine that the reduction in the retail allocation is consistent with the General Plan. Traffic As noted above, a transfer within Newport Center must not result in an adverse traffic impact. Austin -Foust Associates was retained by the City Traffic Engineer to undertake a traffic analysis for the proposed project, including the impacts not only of the 42,012 square feet of general office use (not medical), but also the elimination of 45,119 square feet of retail space within Fashion Island. The analysis was undertaken in accordance with the provisions of the Traffic Phasing Ordinance (TPO), and also included a number of cumulative projects within the vicinity of the project. The project results in an average daily trip (ADT) generation of 589 trips. However, those trips are offset by a reduction of future trips (total ADT of 883) from the transfer of the retail space from Fashion Island, and results in an overall net decrease of 294 trips. Corporate Plaza West November 17, 2005 Page 4 Despite an overall decrease in ADT, it was recognized the project could have impacts on specific intersections, particularly the Clubhouse Drive (Irvine Terrace) /Coast Highway intersection. Therefore, the Traffic Analysis evaluated the project's impact on ten intersections and included an evaluation pursuant to the Traffic Phasing Ordinance (TPO). Using these thresholds, if a project contributes more than one percent to an increase in an intersection's operation during the morning and afternoon peak, the intersection would undergo further Intersection Capacity Utilization (ICU) analysis. Project related traffic increased the traffic by a minimum of one percent at five of the study intersections and an ICU analysis was performed. The ICU analysis concluded that all five will continue to operate at a Level of Service (LOS) of "C" or better and no impact to these primary intersections would occur. The traffic study also evaluated the closest intersection to the proposed office building Clubhouse Drive /Coast Highway. The intersection currently operates at an LOS "A" during the morning and evening peak. The proposed project will cause a slight increase in the AM and PM peak traffic volumes but it will continue to operate at LOS "A" with completion of the proposed office building. The Traffic Analysis is included as Exhibit 4 and staff believes that the findings for the approval of the traffic study are met. Finally, based upon the limited impact of the proposed transfer, staff believes that the transfer can be found consistent with the Land Use Element. Parking Since the proposed project will be constructed on a portion of an existing parking lot that serves the existing office buildings within Corporate Plaza, staff evaluated the parking for not only the proposed project, but also the entire Corporate Plaza area. The Parking Regulations of the Zoning Code require office projects to be parked at a standard of one parking space for each 250 square feet of net floor area (gross floor area less elevator shafts, mechanical rooms and upper floor stairwells). The following chart summarizes the required and provided parking for the project and the entire Corporate Plaza area: Parkina Summa profct I,a' t- Ft000rAtea R€�gtrrrecl ParkpVj PItded ilintj r Existing (Phase 1) 96,502 sq. ft. 386 386 Proposed (Phase 2) 40,013 sq. ft. 161 166 Total 136,515 sq. ft. 547 552 It must be noted that the analysis does not include the bank building located at the intersection of Grandville Drive and Newport Center Drive. This building is located within the General Plan sub area referred to as Corporate Plaza West, but it is not within the Corporate Plaza West Planned Community. The building is not controlled by the applicant and it provides its own parking supply. The Zoning Code also provides that parking may be based on a parking pool for the office buildings and may be modified to provide parking at a rate of one space for each 250 square feet of net floor area for the first 125,000 square feet, and one space for Corporate Plaza West November 17, 2005 Page 5 each 300 square feet over 125,000 up to 425,000 square feet. Using the "parking pool" method, the project and adjacent existing buildings would require a total of 538 parking spaces. Therefore, the project exceeds the required parking using either method. Although more than the minimum number of spaces is provided, staff noticed that the distribution of parking spaces favored the existing buildings. In addition, it should be noted that 119 parking spaces are shared pursuant to a private agreement with the Balboa Bay Tennis Club. Under the provisions of the "Shared Parking and Access Agreement," the Irvine Company has the use of the parking lot and the Tennis Club has a non - exclusive parking easement and use of the Corporate Plaza West parking on Saturdays, Sundays and holidays. There are 123 parking spaces (six spaces located within the Tennis Club shared lot) 300 feet from the proposed building's main entrance and there are 177 spaces (six within the Tennis Club lot) within 300 feet from all of the entrances to the new building. This supply seems adequate based upon the number of spaces; however, many of these spaces are located within the same proximity of the existing buildings and may not always be available. In order to avoid parking distribution issues, staff recommends that a parking lot management plan be implemented such that tenants are required to have employees park in various areas delineated to avoid conflicts. In summary, it is staffs opinion that the project will be adequately parked. Corporate Plaza West Planned Community Development Standards The proposed project is consistent with the site development standards of the Corporate Plaza West Planned Community Development Standards and the standards of the Zoning Code with respect to setbacks, landscaping and building height. However, the plan elevations (Sheet No. A -3.01) indicates wall sign areas that are 3 feet high for primary tenants, and 2 feet high for secondary tenants. The PC permits primary tenant identification signs of up to 24 inches high (letter height) and secondary tenant identification signs of up to 16 inches in height. The applicant has stated that they intend to meet the sign standards of the PC Text, and that the elevations are intended to show the locations of the wall signs. Nevertheless, staff has included a condition in the draft resolution requiring wall signs not to exceed the maximum letter height as stipulated in the PC text. The applicant proposes architectural design and color palette for the new building that is consistent and similar to the existing buildings within Corporate Plaza West: Contemporary Mediterranean with crown molding parapets. Wall finishes, colors and window treatments will match the existing office building to the east. A preliminary landscaping plan has been submitted with the project and the plan indicates a plant palette to blend with the landscaping of the existing office buildings. Parking lot trees proposed in the new parking lot will exceed the PC Text requirement of one tree per five parking spaces. Corporate Plaza West November 17, 2005 . Page 6 Environmental Review After evaluating the project with respect to the California Environmental Quality Act (CEQA) staff determined that a Mitigated Negative Declaration was required. An Initial Study and Mitigated Negative Declaration was prepared, circulated and filed both with the County Clerk/Recorder and the State Clearinghouse. The IS /MND was filed and posted for a period of 30 days for a public review period from October 14, 2005 through November 14, 2005 in accordance with the CEQA Guidelines. A copy of the IS /MND is included as Exhibit 3. CONCLUSION Staff believes that the proposed transfer of development allocation within Newport Center can be found consistent with the General Plan as no adverse traffic impact is anticipated and the resulting construction is compatible with the Corporate Plaza West Planned Community.

WHEREAS, a public hearing was held on November 17, 2005 in the City Hall Council Chambers, 3300 Newport Boulevard, Newport Beach, California. A notice of time, place and purpose of the aforesaid meeting was given. Evidence, both written and oral, was presented to and considered by the Planning Commission at this meeting. WHEREAS, the Land Use Element of the General Plan provides within the Newport Center Planned Community (Statistical Area 1-1) that transfers of development rights are permitted within the Statistical Area, provided that findings are made that the transfer is consistent with the General Plan and will not result in any adverse traffic impacts. WHEREAS, the applicant proposes the construction of a professional office building at the recipient (Corporate Plaza West) and Land Use Element of the General Plan designates site Administrative, Professional & Financial Commercial. The proposed construction and use resulting from the transfer of development allocation is consistent with this designation. The reduction of retail commercial development allocation at Fashion Island does not impact the ability to develop Fashion Island in accordance with the General Plan. WHEREAS, the proposed transfer is consistent with the general development policies of the General Plan as follows: General Plan Policy B, in that the proposed transfer of development rights will not result in significant changes to long range traffic service levels; 2. General Plan Policy C, in that adequate on -site parking will be provided for Corporate Plaza West for the proposed new office building and other existing uses within the Planned Community; N, City of Newport Beach Planning Commission Resolution No. _ Page 2 of 4 3. General Plan Policy D, in that the project will not result in restriction to public views and will not result in adverse impacts to sensitive habitat; 4. General Plan Policy F, in that the project is consistent with the Zoning Code land uses and development standards for the district within which the project is proposed; and 5. General Plan Policy L, in that the proposed project will not result in adverse impacts to area -wide and City -wide prosperity, and will provide additional office space in an area designated for such use. WHEREAS, a traffic analysis has been completed by Austin -Foust Associates, dated August, 2005, that demonstrates that the proposed transfer of development rights will not result in adverse impacts, and will improve the overall traffic circulation within the general area of the proposed project. Specifically, the Planning Commission makes the following findings with respect to the traffic analysis: 1. The traffic analysis was prepared in compliance with Chapter 15.40 of the Municipal Code (Traffic Phasing Ordinance). 2. The traffic analysis considered the transfer of development rights consisting of 45,119 square feet of unused retail space from Fashion Island, and the traffic impacts of the transfer as well as the traffic impacts of the proposed new 42,012 square feet of commercial office space. 3. The traffic analysis indicates that the project, including the transfer of development rights, will result in a net decrease in average daily trips and will not increase traffic at five (5) of the ten (10) primary intersections by one percent (1 %) and therefore no impact is predicted. 4. The Intersection Capacity Utilization Analysis determined that the project will not cause nor make worse an unsatisfactory level of service at any of the five (5) primary intersections where there will be an increase of more than one percent (1 %) in traffic volume and, therefore no mitigation is required. 5. Construction of the project will be completed within sixty (60) months of the approval of the Planned Community Amendment approval by the City Council or the approval of a new traffic study will be required. WHEREAS, the proposed office building is consistent with the development standards of the Zoning regulations of the Municipal Code and the Corporate Plaza West Planned Community, including building setbacks, building height, landscaping and parking. WHEREAS, the proposed office building will be consistent and compatible with the existing land uses in the vicinity and will not be detrimental to the public health, safety, peace, K City of Newport Beach Planning Commission Resolution No. _ Page 3 of 4 comfort, or welfare of persons residing or working in or adjacent to the neighborhood of such use; and will not be detrimental to the properties or improvements in the vicinity or to the general welfare of the City in that the proposed use is compatible with surrounding land uses, has no adverse impacts on area traffic, provides sufficient parking, does not block public views or access to the coastline and other significant man -made and natural features, and the project will provide landscaping and screening. WHEREAS, an Initial Study was prepared in accordance with the Guidelines of the California Environmental Quality Act (CEQA). Based on that Initial Study, a determination was made that the project would require a Mitigated Negative Declaration (MND), said MND having been prepared, posted and circulated in accordance with the provisions of CEQA. Further, given that the project will require review and approval by the California Coastal Commission, the MND was filed with the California Coastal Commission on October 14, 2005 for a 30 -day review period, said review period lasting until November 14, 2005. The Mitigation Measures contained within the MND having been incorporated into conditions as recommended to the City Council. Now, therefore the Planning Commission hereby resolves as follows: The Planning Commission of the City of Newport Beach hereby recommends to the City Council the approval of Planned Community Amendment No. 2005 -001 and Traffic Study No. 2005 -004, subject to the conditions set forth in Exhibit "A ".

CHECKLIST Page 16 $3 The references and sources used for the analysis are also identified with each response 1. AESTHETICS The proposed project is located in a developed urban area that includes primarily commercial office uses to the east, commercial recreation to the north and west and single family residential to the south across East Coast Highway. The project site is currently approximately 50 percent developed with a parking lot associated with the existing office buildings identified as Corporate Plaza West, Phase 1. The project site is adjacent to Coast Highway, a major divided six -lane roadway providing regional north -south access through the City. Therefore, the site and project improvements when completed will be highly visible to vehicular traffic in both directions along East Coast Highway. However, the project will not block public views of the Coastline or other significant public view features. a) Would the project have a substantial adverse effect on a scenic vista? Less than Significant Impact. As noted above, the project site is highly visible from East Coast Highway. However, the project, upon completion will not adversely impact any public views or a scenic vista. The project site is located on the east side of the highway and is not between the highway and the coast. The surrounding areas are urban and developed. b) Would the project substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings with a state scenic highway? Less than Significant Impact. The project, even though highly visible from East Coast Highway, will not block or Impede public views of the coastline, ocean or other public scenic resources. Coast Highway is not a designated Scenic Highway, and no historic buildings will be affected by the project The site has been developed with parking and associated landscaping for the existing office buildings to the east C) Would the project substantially degrade the existing visual character or quality of the site and its surroundings? Potentially Significant impact Unless Mitigation incorporated. The project site is characterized as an urbanized area consisting of a business park, and the site is partially developed with a parking lot for existing office buildings located on the same property. The project is highly visible from East Coast Highway and the vehicular traffic on that roadway in both directions. In addition, the site would be visible from the existing office and recreational uses to the north and east However, due to the screening wall, landscaping, East Coast Highway and orientation of the homes in the Irvine Terrace residential neighborhood, the project will not be viewed from those homes. Nevertheless, the project will result in introduction of a two -story office building on a site currently utilized for landscaping and parking lot for the adjacent office buildings. d) Would the project create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? Potentially Significant Impact Unless Mitigation incorporated. The project will introduce a new two -story office building with associated parking to an area currently developed with a parking lot and landscaping. Even though the existing parking lot contains security lighting, the new office building will introduce a new light source from interior lighting and exterior building- mounted light fixtures. Mitigation Measures: The following mitigation measures are proposed to mitigate the potential impacts associated with items I.(a) and I.(d): Mitigation Measure 1 -1 — The project site shall include a landscaping plan consisting of trees and shrubs designed to complement the building architecture, surrounding landscaping, and screen parking areas and above -ground utilities such as electrical meters, stand pipes and utility vaults. Mitigation Measure 1 -2 — All exterior lighting, including both parking lot standards and building - mounted security lighting, shall be equipped with shields designed to restrict light and glare to the project site and to avoid any light spillage to surrounding properties and uses. CHECKLIST Page 17 (� 3 AGRICULTURAL RESOURCES a) Would the project convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance 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. No Prime Farmland, Farmland of State or Local Importance, or Unique Farmland occurs within or in the vicinity of the site. The site and adjacent areas are not designated as prime, unique or important farmlands by the State Resources Agency or by the Newport Beach General Plan. Therefore, no impact on significant farmlands would occur with the proposed project. b) Would the project conflict with existing zoning for agricultural use, or a Williamson Act contract? No Impact The Newport Beach General Ptan, Land Use Element designates the site as "Administrative, Professional & Financial Commercial" and the zone designation for the site is "Planned Community (PC -40), Corporate Plaza West." The property is designated for commercial office use within the PC text. Therefore, there is no conflict with zoning for agricultural use, and the property and surrounding properties are not under a Williamson Act contract. c) Would the project involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to nonagricultural use? No Impact. The site is not being used for agricultural purposes and is not designated as agricultural land. Therefore, no agricultural uses on the site or within the site's vicinity would be converted to non - agricultural use. III. AIR QUALITY a) Would the project conflict with or obstruct implementation of the applicable air quality plan? No Impact The project was evaluated using the URBEMIS 2002 Model which analyses both mobile source and stationary source emissions. The model, developed by the Southern California Air Quality Management District ( SCAQMD), provides a fair estimate of projected emissions. Based on that analysis, the following daily emissions would be generated by the project While the project will generate some measurable daily emissions, such emissions would not exceed SCAQMD thresholds and the project would not obstruct or conflict with SCAQMD's Air Quality Plan. Therefore, the project would not result in significant air quality impacts. b) Would the project violate any air quality standard or contribute substantially to an existing or projected air quality violation? Potentially Significant Unless Mitigation Incorporated. The proposed project would lead to temporary construction emissions that may affect regional air quality. Temporary construction activity emissions will occur during the construction stage of the proposed development, including the on -site generation of dust and equipment exhaust, and off -site emissions from construction employees commuting to the site and trucks delivering building materials. Heavy -duty trucks, earth movers, air compressors, and power generators would be used during the construction phase. Operation of these vehicles and machines would temporarily increase air CHECKLIST Page 18 3� pollutant levels in the vicinity of the proposed project. In addition, emissions from delivery and haul trucks, construction crew vehicles, concrete mixers, and other off-she vehicle trips would add to local pollutant levels. Given the relatively limited size of the project, and the fact that the site is already rough graded and partially landscaped, construction emissions for CO, ROC, Sox and PM -10 would generally be low from equipment use and truck trips. However, the use of diesel fuel in most of the equipment and trucks would lead to Increased NOx levels. In addition, VOC emissions from paints and coatings would create ROG emissions during construction. Dust emissions on site would be generated by grading and initial construction activities. However, given the flat nature of the site, little grading is proposed and total cut and fill, including import and/or export of soils, is likely to be very limited. Once constructed. and operational, the proposed project will generate 589 new vehicle hips to the area roadways. The new vehicle trips generated by the project on completion are reflected in the URBEMIS 2002 run for a worst - case proposed project build -out year of 2007 (see response to Ill.a, above). As noted in the URBEMIS model run, the project will not exceed SCAQMD thresholds. Not reflected in the URBEMIS model run is the fact that the 42,012 new square feet of office use will be offset by a transfer of approximately 45,000 square feet of retail commercial square footage from Fashion Island. This transfer will actually translate into an off -set of the projects 589 average daily trips (ADT) by the decrease of 883 ADT, resulting in an overall decrease of 294 ADT (see discussion under Section XV, Transportation/Traffic, below). Similar to the project operational emissions, the proposed project- related mobile source emission would not exceed designated thresholds and all pollutant emissions are considerably below significance levels. Therefore, operation of the proposed project would not result in a significant impact to air quality. c) Would the project 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)? No Impact. As discussed above, construction and vehicle emissions associated with the proposed project would not exceed SCAQMD thresholds with implementation of the mitigation measures outlined below. There are not "hot spot CO impacts (either individually or cumulatively) associated with implementation of the proposed office building project. d) Expose sensitive receptors to substantial pollutant concentrations? No Impact. There are no sensitive receptors, such as senior housing, hospitals, schools or public parks located near the proposed project site. e) Create objectionable odors affecting a substantial number of people? No Impact. The proposed project will result in the development of an office building, which will not involve the use of large quantities of solid waste materials, chemicals, food products, or other odorous materials. Therefore, the project does not have the potential to create objectionable odors. There may be temporary odor emissions during construction of the project from construction equipment diesel exhausts and asphalt paving, but such odors are brief and would not threaten regional air quality standards. Mitlgatlon Measures: The following mitigation measures are proposed to mitigate the potential impacts associated with item III.(a): Mitigation Measure 111 -1 — During grading activities, any exposed soil areas shall be watered twice per day. On windy days or when fugitive dust can be observed leaving the proposed project site, additional applications of water shall be applied to maintain a minimum 12 percent moisture content as defined by SCAQMD Rule 403. Under windy conditions where velocities are forecast to exceed 25 miles per hour, all ground disturbing activities shall be halted until winds that are forecast to abate below this threshold. In addition, the project shall comply with all provisions of SCAQMD Rules 402 and 403 Mitigation Measure III -2 — Where vehicles leave the construction site and enter adjacent public streets, the streets shall be swept daily or washed down at the end of the work day or otherwise washed within 30 minutes of any CHECKLIST Page 19 6 tracking extending for more than fifty feet from the project site access point. Any required watering shall meet the requirements of the Santa Ana Regional Water Quality Control Board (SARWQCB). Mitigation Measure III-3 — The construction contractor shall utilize electric or natural gas- powered equipment Instead of gasoline or diesel- powered engines where feasible. If LPG/CNG equipment is available at comparable cost, the applicant shall specify the use of such equipment during the construction phase. All diesel- powered vehicles and gasoline - powered equipment shall be turned off when not in use for more than five minutes. Mitigation Measure 111-4 — The construction contractor shall time the construction activities so as not to interfere with peak hour traffic. To minimize obstruction of through traffic lanes adjacent to the site, a flag person shall be retained to maintain safety adjacent to existing roadways, if deemed necessary by the City. Mitigation Measure III -5 — The construction contractor shall encourage ridesharing and transit incentives for the construction workers. Mitigation Measure 111-6 — To the extent feasible, pre- coated/natural colored building materials shall be used. Water -based or low VOC coatings shall be used that comply with SCAQMD Rule 1113 limits. Spray equipment with high transfer efficiency, or manual coatings application such as paint brush, hand roller, trowel, etc. shall be used to reduce VOC emissions, where practical. Paint application shall use lower volatility paint not exceeding 100 grams of ROG per liter. IV. BIOLOGICAL RESOURCES a) Would the project 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? No Impact. The project site is in an urban setting and the site and surrounding area have been developed for a number of years. The site is currently developed with a parking lot and landscaping. No candidate, sensitive or special status species have been identified on the site or surrounding areas. b) Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural community Identified in local or regional plans, policies, regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? No Impact. See response to (V.a above. c) Would the project 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?. No Impact. The project site is not a wetland and a 404 Permit is not required. d) Would the project 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 native wildlife nursery sites? No Impact. The project site and surrounding areas are developed and therefore the project will not interfere with resident or migratory fish or wildlife species. e) Would the project conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? No Impact. There are no policies or ordinances that would be impacted by the project with respect to biological resources. The project will result in the removal of introduced trees, shrubs and ground covers currently existing on the site and within the existing parking lot However, replacement plants will be installed at the completion of construction. CHECKLIST Page 20 f) Would the project 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. There are no local, regional or state habitat conservation plans affected by the proposed project V. CULTURAL RESOURCES a) Would the project cause a substantial adverse change In the significance of a historical resource as defined §15604.5? No Impact. The project site and surrounding areas have no identified historical buildings, sites or resources. b) Would the project cause a substantial adverse change in the significance of an archaeological resource pursuant to §15604.5? No Impact. The project site and surrounding areas are developed and there is no evidence of archaeological resources. C) Would the project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? No Impact. The project site and surrounding areas are developed and there are no unique geologic features on the site or within close proximity to the site. No significant paleontological resources have been Identified on the site or within surrounding areas. d) Would the project disturb human remains, including those interred outside of formal cemeteries? No Impact. The project site and surrounding areas are highly disturbed due to past urban development and there is no evidence of human remains or sites of native American burials. VI. GEOLOGY AND SOILS a) Would the project expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: 1) 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? Less than Significant Impact. There are no known local or regional active earthquake faults on or in dose proximity to the site, and the site is not within an Alquist - Priolo Zone. The Newport - Inglewood Fault is located approximately 2.5 miles to the southwest of the site, and the San Andreas Fault is located more than 50 miles to the northeast Episodes on those two faults could cause ground shaking at the project site, but it is highly unlikely that there would be ground fault rupture. Even though the project site and surrounding areas could be subject to strong ground movements, adherence to current building standards of the City of Newport Beach would reduce ground movement hazards to acceptable levels. 11) Strong seismic ground shaking? Less than Significant Impact. See response to VI.a. Ili) Seismic - related ground failure, including liquefaction? Less than Significant Impact. The site and surrounding areas are relatively flat, and have been developed for a number of years. The project is not expected to be subject to seismic- related ground failure, such as landslides or liquefaction. A sotlstgeologic survey and report will be prepared prior to issuance of building permits, and any identified unstable soils will be removed from the site, or the site will be engineered accordingly. CHECKLIST Page 21 31' iv) Landslides? No Impact. See response to VI.a.iii above. b) Would the project result In soil erosion or the loss of topsoil? No Impact. The project site and surrounding areas are relatively flat and loss of topsoil is not likely. Dust and erosion control measures will be required during the construction phase of the project, and there will be mandatory grading and building permit requirements. C) Would the project 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? No Impact. The project site and surrounding area are not known to be located within an unstable geologic area and, therefore, not expect to be exposed to or create on- or off -site landslide, lateral spreading, subsidence, liquefaction or collapse hazards. d) Would the project be located on expansive soil, as defined in Table 187 -18 of the Uniform Building Code (1894), creating substantial risks to life or property? No impact. The Newport Beach General Plan Public Safety Element designates the project site and surrounding area as "Category 2" expansive and collapsible soil hazard area. "Category 2" areas are defined as having moderate to high possibility for expansive soil hazard. However, the project site and surrounding areas have been developed and fill soils introduced that are adequate to support buildings. A geologicfsoiis analysis will be completed as part of the building permit process, and additional building permit measures will be incorporated into the design plans to ensure structural safety associated with expansive soils. e) Would the project have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water? No Impact. The project will be connected to existing sewer lines. No septic tanks or alternative waste water disposal systems are proposed. VII. HAZARDS AND HAZARDOUS MATERIALS a) Would the project create a significant hazard to the public or the environment through routine transport, use, or disposal of hazardous materials? No Impact. Construction activities would involve the use of hazardous materials such as oil, gas, tar, cleaning solvents and paint. Transport of these materials to the site and use on the site could add hazards in the event of accidents or spills on area roadways. Hazardous materials use, transport, storage and handling would be subject to federal, state and local regulations to reduce the risk of accidents. Equipment maintenance and disposal of vehicular fluids is subject to existing regulations, including the National Pollutant Discharge Elimination System (NPDES), to prevent contamination of soils. In addition, trash enclosures will be required to be maintained with covered bins and other measures to prevent spillage and/or seepage of materials into the ground. Given the limited nature of the project in terms of scope and size, it is anticipated that normal storage, use and transport of hazardous materials will not result in undue risk to construction workers on the site or to persons on surrounding areas. The use and disposal of any hazardous materials on the site and in conjunction with the project will be in accordance with existing regulations. On -going operation of the site as an office building will not result in the storage or use of hazardous materials on -site, other than normal cleaning solvents. b) Would the project 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? CHECKLIST Page 22 3� No Impact. See responses to Vila above. C) Would the project emit hazardous emissions or handle hazardous or acutely hazardous material, substances, or waste within one-quarter mile of an existing or proposed school? No impact. The closest schools to the project site are Corona Del Mar High School, Lincoln Elementary School, Harbor View Elementary School and Harbor Day School (private). All four schools are located approximately 1.5 to 2.0 miles from the project site, and will not be impacted by construction activities on the site. d) Would the project be located on a site which is included on a list of hazardous materials sites which complied 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. The proposed project site is not on a list of hazardous materials site. e) For a project 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 project site is located approximately five miles south of John Wayne Airport and is not located within an airport land use plan. Operations at John Wayne Airport will not pose a safety hazard for workers and visitors to the office building once the office building is completed and operational. 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. There are no private airports within the vicinity of the project site. g) Would the project impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? No Impact. The project site will not interfere with an emergency evacuation plan, and the site is not adjacent to an emergency evacuation roadway, although Coast Highway serves north -south traffic, including emergency vehicles. As noted in the attached Traffic Analysis (Austin- Foust, 2005), the traffic generation upon completion of the project is not expected to decrease Levels Of Service (LOS) at major area intersections during peak operation periods, and there are not expected to be traffic Impediments to emergency vehicular use as a insult of the project. h) Would the project expose people or structures to a significant risk of loss, injury or death Involving wildiand fires, Including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? No Impact. The project site and surrounding areas are not located within a "Potential Fire Hazard Area° as identified by the Newport General Plan Public Safety Element VIII. HYDROLOGY AND WATER QUALITY a) Would the project violate any water quality standards or waste discharge requirements? No Impact. The project site is currently developed with a parking lot and landscaping, and increase in stormwater runoff is anticipated to be minimal. Existing storm drains will accommodate the runoff of rainwaters from the site. A Stormwater Pollution Prevention Plan (SWPPP) and Water Quality Management Plan (WQMP) incorporating Best Management Practices (BMPs) are required of the project to ensure stormwater impacts are minimized or eliminated to the maximum extent possible. CHECKUST Page 23 b) Would the project 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 pro- existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? No Impact.. The project will result in an increase in water demand, but given the office use of the project, the demand is expected to be minimal and can be accommodated by the domestic water purveyor (City of Newport Beach). There are no water wells located on or near the site, and the project will not result In the lowering of the water table. C) Would the project substantially alter the existing drainage pattern of the site or 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? No Impact The project is relatively flat and will not alter existing drainage patterns. No erosion or siltation will result from the project construction or operation, and acceptable stormwater runoff measures for winter months during construction will provide normal mitigation. d) Would the project substantially after the existing drainage pattern of the site or area, including through the alteration of a 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? No Impact The project site is currently partially developed as a parking lot. Development of the site will result in additional ground coverage with resultant stormwater runoff amounts, but the amount of Increase is anticipated to be normal and can be accommodated by existing storm sewers and drainage facilities. e) Would the project 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? Less than Significant Impact. See response to VIII.d above. f) Would the project otherwise substantially degrade water quality? No Impact. See responses to Vlil.a and d above. g) Would the project 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. No housing is proposed with the project. The project site is not located within a 100 -year flood hazard area as identified by the latest Flood Rate Maps. h) Would the project place within a 100 -year flood hazard area structures which would impede or redirect flood flows? No Impact. See response to Vlil.g above. i) Would the project 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 The project site is not within a flood hazard area or within an area subject to flooding due dam or levee failure. J) Would the project be subject to Inundation by selche, tsunami, or mudflow? CHECKLIST Page 24 Ld No Impact. The project site Is in dose proximity to the Pacific Ocean. However, given the location inland from the beach, intervening Newport Bay and urban land uses, and the elevation of the site 101 feet +), it is untikety !list the project site would be subject to inundation -by setche, tsunami, or mudflow. k) Would the project result in significant alteration of receiving water quality during or following construction? No Impact. See response to MILa above 1) Would the project result in potential for discharge of stormwater pollutants from areas of material storage, vehicle or equipment fueling, vehicle or equipment maintenance (including washing), waste handling, hazardous materials handling or storage, delivery areas, loading docks or other outdoor work areas? No Impact. Given the office uses proposed for the project site, the project will not result in pollutants associated with material storage, vehicle or equipment fueling or maintenance, waste handling or storage or other outdoor work areas. m) Would the project result in the potential for discharge of stormwater to affect the beneficial uses of the receiving waters? Less than Significant Impact. See response to Vlli.a above. n) Would the project create the potential for significant changes In the flow velocity or volume of stormwater runoff to cause environmental harm? No Impact. The project site is relative flat and the project will not result in.alteration of stormwater patterns or velocities, or a significant increase in stormwater volumes. o) Would the project create significant increases In erosion of the project site or surrounding areas? Less than Significant Impact. See response to Vlll.n above. Stormwater runoff from the project upon completion can be handled by existing curbs, gutters and storm drains. IX. LAND USE AND PLANNING a) Would the project divide an established community? No Impact. The project is proposed to be located in a portion of a site currently developed with an office complex, and would not introduce a new use to an existing neighborhood. b) Would the project conflict with any land use plan, policy, or regulation of an agency and 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? Less than Significant Impact. The Land Use Element of the Newport Beach General Plan designates the site as "Administrative, Professional & Financial Commercial" The site is located within the Newport Center Planned Community (Statistical Area L1, Subarea 12 (Corporate Plaza West), and is designated for 115,000 square feet of professional office use. Included in the General Plan provisions for Newport Center is the following: Transfers of Development Rights in Newport Center are permitted, subject to approval of the City with the finding that the transfer is consistent with the intent of the General Plan and that the transfer will not result in any adverse traffic Impacts° (Land Use Element, page 77). The applicant proposes to transfer a total of 45,119 square feet of unbuilt retail square footage from Fashion Island (Subarea 18) to Corporate Plaza West (Subarea 12). In order to make the finding relative to traffic impacts, a traffic analysis has been completed and is attached as an Addendum to this Initial Study (see discussion under Section XV, Transportation/Traffic). CHECKLIST Page 25 qX The project site is zoned "Planned Community (PC -40)" and is designated for commercial office use. The Corporate Plaza West Planned Community indicates an office building on the site, but limits the total floor area to 115,000 square feet. As noted above, the applicant proposes to transfer 45,119 square feet from Fashion Island. Therefore, it is necessary to process a Planned Community Development Amendment to increase the total floor area within Corporate Plaza West and to correspondingly decrease the floor area within Fashion Island to reflect the transfer of development rights. The Local Coastal Plan (LCP) land use plan designates the site as Administrative Professional and Financial Commercial. Therefore, the proposed project will be consistent with the LCP. in addition, the project is located on the inland side of Coast Highway and does not interfere with public access nor public views of the coastline, and the project does not obstruct a public accessway, trail or bikeway that provides access to the coastline. The site's location on the east side of Coast Highway makes it unfeasible to provide public parking or other public access facilities for public coastal access. C) Would the project conflict with any applicable habitat conservation plan or natural community conservation plan? No Impact. The project is not in conflict with any conservation plan — see response to IV.f above. X. MINERAL RESOURCES a) Would the project 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. The proposed project is not located in an area where there are known mineral resources, and development as proposed would not affect regionally significant mineral resources. b) Would the project result in the to 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. The proposed project site is not identified In the Newport Beach General Plan as a significant mineral resource area. XI. NOISE a) Would the project result in 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 of other agencies? Potentially Significant Unless Mitigation Incorporated. implementation of the proposed project would result in short-term, construction- related noise Increases associated with grading, equipment operations and other construction activities. Noise levels generated by these operations generally range from 75 to 100 dBA at 50 feet from the source. The nearest residential use to the site are the homes in the Irvine Terrace neighborhood, located approximately 150 feet to the south. However, that residential neighborhood is separated from the project site by Coast Highway (six travel lanes and median island) and the wall and landscaped parkway on the south side of the street. The temporary increase in ambient noise levels would be buffered by. the street, wall and landscaping; however additional mitigation as recommended below would decrease the impact to the residential and other existing surrounding land uses. Long -term increased noise levels could result from the introduction of a new office use and associated vehicle traffic along the adjacent streets. However, given the relatively minor increase in traffic (refer to discussion under Section XV below), the increase in noise levels is not anticipated to be significant. The project site is located adjacent to Coast Highway, and the Noise Element of the General Plan Indicates that a portion of the site, including portions of the proposed new office building, are located within the 65 CNEL noise contour. Therefore, there is the potential for exposure of persons working within the building to high noise levels resulting from traffic along Coast Highway. Mitigation measures to reduce the interior noise levels to acceptable levels are included below. CHECKLIST Page 26 q3 b) Would the project result In exposure of persons to or generation of excessive groundborne vibration or groundborns noise levels? Potentially Significant Unless Mitigation Incorporated. See response to Xl.a above. Mitigation measures follow. c) Would the project result in a substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? Less than Significant Impact. See response to XLa above. d) Would the project result in a substantial temporary or periodic increase in ambient noise levels In the project vicinity above levels existing with the project? Potentially Significant Unless Mitigation Incorporated. See response to Xi.a above. Mitigation measures follow. 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 not within an airport land use plan or within two miles of an airport. Q 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. The project site is not within the vicinity of a private airport. Mitigation Measures: The following mitigation measures are proposed to mitigate the potential impacts associated with items XI. (a), (b) and (d): Mitigation Measure XI -1 — Construction activities shall be confined to the hours of 7:00 a.m. and 6:30 p.m. on weekdays and on Saturdays between the hours of 8:00 a.m. and 6:00'p.m. No construction activities shall occur on Sundays or any federal holiday. Mitigation Measure XI -2 — All vehicular and petroleum -driven equipment shall be equipped with mufflers. Mitigation Measure XI -3 — Idling of construction vehicle and equipment shall be limited to the extent feasible. Vehicles shall be property maintained, and shall be turned off when not in use. Mitigation Measure XI-4 — The proposed office building shall be constructed using double pained windows and insulation to maintain interior noise levels at 45 dBA or less. Any exterior equipment such as heating and air conditioning shall be furnished with baffles, screens and/or landscaping to ensure that noise levels from that equipment does not exceed 65 dBA as measured at any project property line. X11. POPULATION AND HOUSING a) Would the project induce substantial population growth In an area, either directly (for example, by proposing new homes and businesses) or Indirectly (for example, through extension of roads or other infrastructure? No Impact. The project will result in a new 42,012 square -foot office building. The applicant proposes to transfer development rights by the transfer of retail commercial square footage on a foot -by -foot basis from Fashion Island. Therefore, there will be no net increase of commercial square footage within the General Plan Statistical Area, in turn resulting in no increase beyond that analyzed initially for the General Plan. While the project may increase the employment, the increase, given the relatively minor nature of the project, is not expected to cause substantial population growth in the area. CMCKLIST Page 27 41 b) Would the project displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? No impact. The project site is zoned for office use and is currently partially developed as a parking lot for the existing adjacent office buildings. No housing or residents will be displaced by the project C) Would the project displace substantial numbers of people, necessitating the construction of replacement housing? No Impact. See response to Xll.b above. All. PUBLIC SERVICES a) Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered government facilities, need for new or physically altered government 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 public services: • Fire protection? Less than Significant Impact. The project will result in a new 42,000 square foot office building that will be offset by transfer of a like amount of commercial square footage from Fashion Island. While the project will result in an additional building requiring emergency and utility services, the increase is minor and has been anticipated by the City's General Plan. • Police protection? Less than Significant Impact. See previous response. • Schools? No Impact. The project will not result in additional residential or additional school -age children. • Other public facilities? No Impact. See responses above. XIV. RECREATION a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? No Impact. The project will result in a new 42,012 square-foot office building located on a site designated for commercial office use and that is partially developed with a parking lot for existing office uses. The project will not occupy a park or recreational facility and will not directly generate additional population or demand for park or recreational facilities. b) Does the project include recreational facilities or require the construction of or expansion of recreational facilities which might have an adverse physical effect on the environment? No Impact. The project will not require expansion or construction of park or recreational facilities. XV. TRANSPORTATIONITRAFFIC A traffic analysis has been completed for the project and is attached as an addendum to this initial Study. a) Would the project cause an increase in traffic which is substantial In relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at Intersections)? CHECKLIST Page 28 N - A Potentially Significant Unteas AAitigatlon incorporated. The traffic analysis prepared for the project took into consideration the proposed transfer of retail commercial space from Fashion Island, as well as a number of cumulative projects within the vicinity of the project. While the project itself will result in an average dairy trip (ADT) generation of 589 trips, those are oftset by a reduction of future trips (883) from the transfer of square footage from Fashion Island, for a net decrease of 294 trips. Given the fact that there will be an increase in traffic at the construction site, a traffic analysis was conducted. The total ADT for the project, including increases in AM peak and PM peak traffic are summarized in the following table: LAND USE UNITS TRIP GENERATION SUMMARY AM PEAK HOUR IN OUT TOTAL IN PM PEAK HOUR OUT TOTAL ADT TRIP RATES (NBTAM) 0 17 0 1 No 3.

In summary, the traffic analysis concludes that there will be no marginal impact and concluded that no mitigation is required. However, given that the project will generate additional traffic and parking, Mitigation Measures have been included in this Initial Study. b) Would the project exceed either individually or cumulatively, a level of service standard established by the county congestion management agency for designated roads or highways? Potentially Significant Unless Mitigation Incorporated. See response to XV.a above. C) Would the project result in a change in air traffic pattern, including either an increase in traffic levels or a change in location that results in substantial safety risks? No Impact. The project will not result in a change in air traffic patterns and will not result in substantial safety risks. d) Would the project 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 will be constructed on an existing site and no off -site improvements or changes are proposed to the surrounding streets and intersections. e) Would the project result in Inadequate emergency access? No Impact. The project would provide an additional source for emergency requests associated with additional employees and clients in the new office building. Given the relatively small -scale of the project size, any increase in emergency demand is relatively insignificant and can be handled by existing emergency services personnel and CHECKLIST Page 30 equipment The traffic analysis completed for the project indicates that the traffic levels on the existing streets and intersections in the vicinity of the project is insignificant, and would actually improve given previously proposed uses in the general area. A fire access plan has been prepared as part of the project review process, and the plan as well as the overall project plans have been reviewed by the City Fire Department and no significant Impacts have been identified. f) Would the project result in inadequate parking capacity? Less than Significant Impact. The project will result in a demand for 161 new parking stalls. The 161 parking spaces will be provided in addition to the parking spaces for the existing office building located to the east of the site. g) Would the project conflict with adopted policies, plans, or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks)? No Impact. The proposed office building will be constructed on an existing site and will not require the realignment of existing streets or the construction of new public transportation facilities in the vicinity. The project may result in a minimal increase in use of public bus ridership by employees and clients, but given the minor nature in the floor area increase, any increase is expected to be accommodated by existing bus service and facilities. Bicycle racks will be required and provided in accordance with City ordinances. Mitigation Measures: Even though the Traffic Analysis prepared for the project concluded that there will be no marginal impacts and did not require mitigation, the following mitigation measures are included for the overall traffic, circulation, and parking mitigations: Mitigation Measure XV -1 — Sight distances at the comer of Irvine Terrace and Coast Highway, as well as the main entry driveway off of Irvine Terrace, shall be provided in accordance with City standards. Mitigation Measure XV -2 — On site traffic signage, driveway striping and fire aisles shall be installed and maintained as required by the City Engineering, Police and Fire Departments. Mitigation Measure XV -3 — Parking lot design shall meet all City standards with respect to drive aisle widths, parking space dimensions, turning radii and driveway /parking surface grades. Mitigation Measure XV-4 — Bicycle racks shall be provided in accordance with City requirements. XVI. UTILITIES & SERVICE SYSTEMS a) Would the project exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? Less than Significant impact Wastewater generated by the proposed new office building would be disposed into the existing sewer system and would not exceed wastewater treatment standards of the Regional Water Quality Control Board. b) Would the project 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. Water demand and wastewater generation will be minimal with a minor incremental increase . associated with the employees and users of the 42,012 square -foot office building. The project will connect to existing water and sewer lines in the vicinity. Existing infrastructure and facilities will be able to service the proposed project. CHECKLWr Page 31 C) Would the project 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 project site is partially developed with a parking lot The project will result in additional impervious service areas by the new building, walkways and other hardscaps. The additional hardscape will result in a slight increase in runoff during storm periods; however, this runoff is minimal and can be accommodated within existing curbs, gutters and stormdrains in the area. d) Would the project have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? No Impact. See response to XVI.b above. Future water demand based on the General Plan projections would not be increased and may even be decreased based on the transfer of development rights on a square -foot per square -foot basis of retail commercial use from Fashion Island. The site is currently landscaped. Implementation of the project will not result in additional water demand associated with irrigation of the associated landscaping around the building and within the parking lot e) Would the project 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? No Impact. See response to XVI.b above f) Would the project be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? No Impact. The project would result in a small incremental increase in solid waste associated with an office building. Given the minor nature of the increase in size and associated solid waste increase, existing landfills are expected to have adequate capacity to service the site and use. The project will be required to participate in City recycling programs. and recycling bin(s) will be provided within the trash enclosures. g) Would the project comply with federal, state, and local statues and regulations related to solid waste? No Impact. The project will be required to comply with all federal, state and local regulations related to solid waste. See response to XVI.f above. MANDATORY FINDINGS OF SIGNIFICANCE The environmental analysis, including the attached traffic report prepared for the project, indicates that the proposed 42,012 square -foot office building would not have the potential for significant adverse environmental impacts with implementation of standard City conditions and the recommended mitigation measures contained herein. Therefore, the following findings can be made regarding the mandatory findings of significance as set forth in Section 15065 of the CEQA Guidelines: a) The proposed project would not have the potential to degrade the quality of the environment There are no sensitive plant or animal species on the project site and the proposed project would not 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, or reduce the number or strict the range a rare or endangered plant or animal. No historic structures or sites, archaeological resources or paleontological resources are present in the project area, which may be affected by the proposed project. The proposed project would not eliminate important examples of the major periods of California history or prehistory. b) The proposed project would not have the potential to achieve short-tern goals to the disadvantage of long -term environmental goals. The proposed project will result in a new 42,012 square -foot office building with associated parking and landscaping on a 12.7 acre site currently developed with two office buildings. Although the project cold have impacts to air quality, noise, aesthetics and transportation/traffic, CHECINST Page 32 q9 mitigation measures would decrease these Impacts to below a level of significance. The project would not significantly impact environmental resources. c) The proposed project would not have environmental impacts, which are individually limited but cumulatively considerable, when considering planned or proposed development in the immediate vicinity of the site. The proposed project would not cumulatively lead to significant adverse impacts, when added to proposed, planned or anticipated development in the area. d) The proposed project would not have environmental impacts, which may have adverse effects on humans, either directly or indirectly, with implementation of the recommended mitigation measures. The project may create short -term noise and air quality impacts during grading and construction. However, implementation of the recommended mitigation measures would avoid significant adverse impacts and would reduce the identified impacts to insignificant levels. The City of Newport Beach has determined that the proposed project would not have significant adverse impacts on the environment with the implementation of mitigation measures, and no additional environmental analysis is warranted. The City would consider adoption of a Mitigated Negative Declaration for the proposed Corporate Plaza West office building project, with the incorporation of the recommended mitigation measures.

In addition, this report summarizes the results of an analysis of cumulative conditions in compliance with California Environmental Quality Act (CEQA) requirements. PROJECT DESCRIPTION l The proposed office building is located on the northeast comer of Irvine Terrace/Clubhouse Drive i and East Coast Highway in the Newport Center area of the City of Newport Beach. The project consists t . of 42,012 square feet of general office space. This office space is proposed in exchange for 45,119 square feet of entitled regional retail space in Fashion Island. Figure I illustrates the location of the project. Figure 2 illustrates the proposed site plan. TRIP GENERATION AND DISTRIBUTION The proposed project consists of 42,012 square feet of general office space. The increase in traffic generated by the proposed office space was added to the surrounding circulation system, and the traffic generated by the entitled regional retail space was subtracted from the circulation system. Trip generation for the proposed project were determined from current Newport Beach Traffic Model trip rates. The regional retail trips are based on the original Fashion Island expansion entitlement in 1994. These rates and the resulting trips are summarized in Table 1. As this table indicates, the proposed project results in a net decrease of 294 trips daily. During the AM peak hour there is a net increase of 71 trips generated compared with the trip generation of the entitled regional retail use. During the PM peak hour the proposed project generates 14 new trips compared with the trip generation of the entitled regional retail use. Not only is there a difference in the amount of trips generated by the proposed project and the i entitled retail use, there is also a difference in the directionality of the trips. The office trips are heavily oriented inbound during the AM peak hour and outbound during the PM peak hour, whereas the retail . trips are relatively balanced between inbound and outbound trips during the AM and PM peak hours. Trip distribution of project - generated traffic onto the surrounding circulation system was determined from observed travel patterns in the vicinity of the project site as well as from locations and l Corponte Plaza West Expansion TPO 1 Austin -Foust Associates, Inc.

The net peak hour trips for the proposed project (including the reduction for the entitled regional retail trips) are illustrated in Figures 9 and 10. TPO TRAFFIC IMPACTS The City of Newport Beach. identified 10 intersections for analysis to determine the impact of the proposed general office development. These intersections are: Jamboree Road and San Joaquin Hills Road Jamboree Road and Santa Barbara Drive Jamboree Road and Coast Highway Irvine Terrace/Clubhouse Drive and Coast Highway Newport Center Drive and Corporate Plaza Entry Newport Center Drive and Coast Highway Avocado Avenue and Coast Highway MacArthur Boulevard and San Joaquin Hills Road MacArthur Boulevard and San Miguel Drive MacArthur Boulevard and Coast Highway Existing (2003 and 2004) peak hour intersection volumes were provided by City Staff. An ambient growth rate of 1.0 percent per year was added to the existing volumes on Jamboree Road, Coast Highway, and MacArthur Boulevard. Construction of the project is assumed to be complete in 2006; therefore, the study year is 2007. Traffic generated by approved projects in the study area, obtained from City Staff, were added to the existing peak hour volumes to obtain year 2007 background peak hour volumes for the intersections prior to the addition of project - generated traffic. Table 2 summarizes the approved projects included in this analysis. Background- plus - project peak hour volumes were obtained by adding the project - generated peak hour intersection volumes presented above to the existing -plus- Corporate Plaza West Expansion TPO 5 Austin -Feast Associates, Inc.

A credit type adjustment for the entitled but yet to be constructed retail trips that are being exchanged for the proposed new office use is included in the background -plus- project volumes. The TPO analysis consists of a one percent analysis and an intersection capacity utilization (ICU) 1- analysis at each study intersection. The one percent analysis compares the proposed project traffic with projected background peak hour volumes. To pass the one percent analysis, peak hour traffic from the proposed project must be less than one percent of the projected background peak hour traffic on each leg 1. of the intersection. If the proposed project passes the one percent analysis, then the ICU analysis is not required and no further analysis is necessary. If the proposed project does not pass the one percent analysis, then the ICU analysis must be performed for the intersection which. fails to pass the one percent I ' test. Table 3 summarizes the results of the one percent analysis (the one percent analysis sheets are included in the appendix). As this table indicates, the proposed project does not pass the one percent 1 . analysis at five study intersections during the AM and PM peak hour; therefore, an ICU analysis is ., required for the intersections of Jamboree Road and Santa Barbara Drive, Irvine Terrace/Clubhouse Drive and Coast Highway, Newport Center Drive and Corporate Plaza Entry, MacArthur Boulevard and San Joaquin Hills Road, and MacArthur Boulevard and San Miguel Drive. S' i; An ICU analysis was performed for the five intersections which did not pass the one percent test. Existing lane configurations were assumed, and a capacity of 1,600 vph per lane with no clearance factor ? was utilized. Table 4 summarizes the existing, background, and background - plus - project ICU values i. during the AM and PM peak hours (actual ICU calculation sheets are included in the appendix). As the ICU summary table indicates, the project will have no-marginal impact on the intersections of Jamboree Road and Santa Barbara Drive, Irvine Terrace /Clubhouse Drive and Coast Highway, j Newport Center Drive and Corporate Plaza Entry, MacArthur Boulevard and San Joaquin Hills Road, and MacArthur Boulevard and San Miguel Drive which will operate at level of service (LOS) "C" or better t during the AM and PM peak hours. The project has no significant impact on the study intersections, and no mitigation is required. . i r' Corporate Plaza West Expansion TPQ Traffic Analysis 15 Austin -Foust Associates, Inc. 0I7076rpt.Jm K Table 3 SUMMARY OF ONE PERCENT ANALYSIS - - -- AM PEAK HOUR PROJECT VOLUMES -- INTERSECTION NB SB EB WB LESS THAN I% OF PEAK HOUR VOLUMES 1.

These cumulative projects are summarized in Table 5. Trip generation and distribution for each cumulative project was also provided by City Staff. The peak hour cumulative intersection volumes were added to the background volumes presented earlier, then project- generated traffic was compared to one percent of the background - plus - cumulative traffic. The results of the cumulative one percent analysis are summarized in Table 6. The proposed project does not pass the one percent test at the five study intersections identified above; therefore, an ICU analysis is required at these study intersections. The results of the cumulative ICU analysis are summarized.in Table 7 (actual ICU calculation sheets are included in the appendix). As the cumulative ICU table indicates, the proposed project will have no significant impact on the study intersections which operate at LOS "D" or better, and no mitigation is required. CONCLUSIONS The proposed project, consisting of.42,012 square feet of general office space in exchange for 45,119 square feet of entitled regional retail space in Fashion Island, will generate 294 fewer daily trips than currently entitled, and 71 more AM peak hour trips and 14 more PM peak hour trips than the entitled uses. The marginal impact of project traffic on the street system was determined at 10 intersections in the vicinity. Five of the 10 intersections did not pass the City's one percent analysis; however, the project had no marginal impact on the ICU values at these five intersections, which will continue to operate at level of service (LOS) "C" or better during the AM and PM peak hours. Consequently, the proposed project has no significant impact on the study intersections, and no additional intersection improvements are required. The impact of traffic from known but not approved projects was included in a cumulative conditions analysis. Under cumulative conditions, the project passed the City's one percent test at all but five study intersections. However, the project had no marginal impact on the ICU values at any of these : five intersections during the AM or PM peak hour. Therefore, the proposed project has no significant - impact on the study intersections under cumulative conditions, and no intersection mitigation measures are required.
