INTRODUCTION: The purpose of this study is to provide a site-specific sewer capacity study to assess the amount of wastewater generated by the proposed development of the project site at 1401 Quail Street, Newport Beach, CA. This sewer study will assess if the city sewer system capacity is sufficient when the project site is redeveloped from a commercial site to a residential site and if the change in the sewer usage complies with the City of Newport Beach’s design criteria indicated in the City’s Sewer Master Plan (SMP). 2 II. EXISTING AND DEVELOPED SITE CONDITIONS: Existing Conditions: The proposed project site, approximately 1.71 acres, is located in the City of Newport Beach, Orange County, California. The site is at the North-West corner of Quail Street and Spruce Avenue and has an existing office building structure along with a surface parking lot. The current land use is for a 1-story office complex. The site is relatively flat and drains from south to north, and is identified as Assessor Parcel Number 427-332- 04. The zoning code is PC-11 and the site is enclosed by an existing parking lot to the West, Spruce Street to the South-East, and Quail Street to the North-East. See Figure 1 in Appendix A for the project Vicinity Map Information. Developed Conditions: The proposed project is comprised of a 7-story podium apartment building with one level of subterranean parking. Vehicular access to the building will be from the proposed driveway entrance on Spruce Avenue. 3 III. EXISTING AND PROPOSED SEWER LAYOUT: Existing Sewer Layout An existing sewer lateral off Spruce Street connects the private street to the existing 8” VCP public sewer main. The public sewer main originates on Spruce Street at the existing sewer laterals, with manhole ID MHM28_019, and drains in the northeast direction to manhole MHM28_018 at Quail Street. The sewer main then increases to a 10” diameter VCP and continues to the southeast to MHM28_033, located at the intersection of Quail Street and Dove Street. The sewer system maintains a 10” diameter and continues to the north to manhole MHM28_003, located at the intersection of Dove Street and Newport Place. The sewer main then increases to 15” diameter and continues to the east to Macarthur Blvd. and then to the north to MHM28_051. The sewer main then increases to an 18” diameter and continues for a short run to MHM27 to discharge in to the Orange County Sanitation District sewer main. For data analyzing purposes, the study will separate this sewer path into 4 different segments. See Figure 1 below for a graphic representation of the existing sewer system. Figure 1. Existing Sewer System at Project Site 4 Proposed Sewer Layout No change to the public sewer system is proposed as part of this project and the existing 8” VCP sewer lateral servicing the site is proposed to be re-used for the development. The only change proposed will be made for the land use of the project site from a commercial use to a residential use. The project site is currently an office complex with a surface-level parking lot. The proposed project will redevelop the site to construct a 7-story 16-unit podium building, with 6 levels of residential apartment over 1 level of slab grade parking garage, and 1 level of sub-terranean parking. The change in use for the site is anticipated to increase the rate of discharge to the system and are further detailed and justified below. IV. DESIGN CRITERIA: IV.1. Sewer Design Criteria Design criteria utilized in this report are based on the City of Newport Beach’s Sewer Master Plan (SMP) prepared by AKM Consulting Engineers (August 2010) The focus of this study is to calculate the generation rates for the existing and proposed development based on land use generation rates in order to calculate the projected ratio of flow depth versus pipe diameter (d/D). d/D Requirements: Based on the City’s SMP, existing sewer pipes are considered deficient if this ratio is greater than 0.6 at peak dry weather flows and 0.8 at peak wet weather flows. Manning’s Friction Factor: Per City’s SMP requirements, a Manning’s friction factor of 0.013 has been utilized on all flow calculations. Flow Generation Rates: Since water use records were unavailable to the parcels in the sewer system, a typical unit flow factor of 2500 gallons per day per acre (gpd/ac) is 5 utilized for the project based on the commercial use and the maps provided in the City’s SMP (See Appendix D). Peaking Factor (Dry Weather): Per the City’s SMP, a peaking factor formal has been applied to the calculated daily generation rates as follows: PDWF (mgd) = 2.20 x ADWF (mgd)0.92 See Table 1 below for a brief summary of the key design factors utilized in the report and Appendix B for a listing of the City’s required design criteria for sewer systems. Table 1. Sewer Design Criteria IV.2. Maximum Allowed Flow The maximum allowed flow for each segment has been determined by identifying the minimum diameter and slope of pipe within the segment, and calculating the flows for the given pipe diameter and slope at a d/D ratio = 0.6. Pipe flows were calculated utilizing the above noted design factors and the software, Hydraulic Toolbox, for each critical pipe segment (See Appendix C). The results of the calculations are included in the Table 2 below. 6 Table 2.

Existing Flow Rates The formula for the Average Dry Weather Flows (ADWF) is a function of the total tributary parcel acreage and the above noted generation rates. The formula is listed below. Q = A * 2500 gpd/ac Where: Q = ADWF (gpd) A = Tributary Area (Acres) Known residential developments captured in this report include: • 1300 Bristol St – 193 units @ 160 gpd/unit • 1400 Bristol St – 221 units @ 160 gpd/unit • 1600 Dove St – 249 units @ 160 gpd/unit • Newport Crossing (1660 Dove St/1701 Corinthian Way) – 350 units See figure 2 below for the assumed tributaries for each segment and refer to Appendix C for a listing of all Area-Based Flow Calculations. 7 Figure 2. Tributary Areas and Existing Wastewater Flows Given the Q values for the segments noted in Figure 2, the Q is converted to million gallon per day (mgd) which was subsequently used to calculate the peak dry weather flow for each segment based on the Peaking Factor Formula provided in the City’s SMP. The calculated peak dry weather flow was then converted to cubic feet per second (cfs) and compared to the maximum allowed flow for the given segment (see 8 Table 2 for reference of existing segment capacities). See Table 3 below for a summary of the total peak flows compared to the maximum allowed flow of each segment. Table 3.

Proposed Flow Rates The total area of the project site at 1401 Quail St, Newport Beach, CA is 1.71 acres. Utilizing the typical unit flow factor of 2500 gpd/ac, the existing flow at the project location is calculated as 4,275 gpd. According to the City’s SMP, the residential unit flow factors range from 110 gpd/du to 240 gpd/du (see Appendix D for the City’s SMP Unit Flow Factor Map). Based on review of similar parcels within the City, a generation rate of 160 gpd/du has been selected for the subject parcel. Given the proposed 78 dwelling units, the calculated daily flow for the proposed condition is 12,480 gpd. As a result, the total increase in daily flow is calculated as the difference between the proposed flow and the existing flow at the project site, being 8,205 gpd. Results of this calculation are summarized below in Table 4: Table 4. Total Daily Flow Increase at the Project Site Existing Flow at Project Site (GPD) Proposed Flow at Project Site (GPD) Total Increase in Flow (GPD) 4,275 12,480 8,205 Based on the above noted increase in daily sewer generation rates, the total system peak flows were re-calculated with the additional 8,205 gpd added into each segment’s calculations. The results of the proposed system flows are presented in Table 5 below. 9 Table 5.

RESULTS AND CONCLUSIONS: Based on the above noted calculations, data, and the City’s SMP guidelines, the existing sewer system does not have adequate capacity to handle the existing sewer generation rates nor the increase in projected daily sewer generation rates. Sewer Segment #3, a 10” VCP sewer main located on Dove Street between Newport Place and Bowspirit Drive, is considered deficient by the City’s design requirements for the depth to diameter ratio. Replacement of the deficient segment will include the removal of the existing 10” VCP and installation of new 12” VCP sewer main. 10 Appendix A: Vicinity Map 11 Appendix B: Sewer Design Criteria 12 Appendix C- Existing Flow Calculations 8 Inch VCP @ 1.0% Slope Segment #1 - MHM28_019 to MHM28_018 10 Inch VCP @ 0.26% Slope Segment #2 - MHM28_018 to MHM28_033 10 Inch VCP @ 0.40% Slope Segment #3 - MHM28_033 to MHM28_003 15 Inch VCP @ 0.20% Slope Segment #4 - MHM28_003 to MHM28_051 18 Inch VCP @ 0.20% Slope MHM28_051 to MHM27 1400 Bristol St (221 DU)2.38 A 1 35,360* 1300 Brsitol St (193 DU)1.97 A 1 30,880* 1401 Quail St 1.70 A 1 4,250 1301 Quail St 1.85 A 1 4,625 SEGMENT 1 SUMMARY 7.90 A -75,115 1400 Quail St 1.47 B 2 3,675 1451 Quail St 0.71 B 2 1,763 1451 Quail St 0.71 B 2 1,763 1500 Quail St 1.59 B 2 3,967 1500 Quail St 0.79 B 2 1,983 1501 Quail St 1.11 B 2 2,775 1501 Quail St 1.11 B 2 2,775 1701 Quail St 1.22 B 2 3,050 1811 Quail St 0.69 B 2 1,725 No Site Address 2.15 B 2 5,381 3880 Birch St 1.21 B 2 3,025 2 Upper Newport Plaza Dr 0.18 B 2 450 6 Upper Newport Plaza Dr 0.76 B 2 1,900 3 Upper Newport Plaza Dr 0.20 B 2 500 4 Upper Newport Plaza 0.54 B 2 1,350 6 Upper Newport Plaza Dr 0.76 B 2 1,900 6 Upper Newport Plaza Dr 0.76 B 2 1,900 7 Upper Newport Plaza Dr 0.31 B 2 775 6 Upper Newport Plaza Dr (Different)0.23 B 2 575 3620 Birch St 0.90 B 2 2,250 3610 Birch St 1.13 B 2 2,825 3600 Birch St 0.93 B 2 2,325 1550 Bristol St N 0.86 B 2 2,150 6 Upper Newport Plaza Dr 0.18 B 2 450 1 Upper Newport Plaza Dr 0.21 B 2 525 3636 Birch St 2.38 B 2 5,950 1800 Quail St 0.51 B 2 1,275 1900 Quail St 0.37 B 2 925 1300 Quail St 1.50 C 2 3,750 1301 Quail St 1.85 C 2 4625 1200 Quail St 1.00 C 2 2500 1100 Quail St 1.15 C 2 2,875 1101 Quail St 1.00 C 2 2,500 1000 Bristol St 3.91 C 2 9775 1000 Quail St 1.52 C 2 3800 895 Dove St 1.98 C 2 4,938 901 Dove St 0.57 C 2 1,425 SEGMENT 2 SUMMARY 46.34 A+B+C -171,210 900 Bristol St 1.00 D 3 2500 3601 Jamboree Rd 2.87 D 3 7,175 895 Dove St 1.975 D 3 4,938 3901 McArthur Blvd 2.67 D 3 6,675 AREA BASED SEWER GENERATION RATES (2,500 GPD/AC) *Flow is increased reflect actual future condition per sewer study reports prepared by Tait & Associates, August 2021 and December 2022.
