TUCCI RESIDENCE 20002 -WQMP Page 6 PA2020-016 Water Quality Management Plan (WQMP) 3905 Marcus Avenue, Newport Beach, CA 11.4 Post Development Drainage Characteristics Post-development roof and site runoff will be collected and conveyed, via downspouts, drain inlets and pipes, in an easterly direction across the project site. The project stormwater then enters a drainbox at the front of the property which discharges into a perforated drain trench (infiltration BMP) beneath the project driveway. Peak storm volumes that exceed the capacity of the perforated drain trench will rise within the drainbox and then discharge through the curb face onto Marcus A venue; from this point, runoff will continue to follow the existing off-site drainage pattern, ultimately discharging to Lower Newport Bay. Infiltration BMPs are discussed in further detail in Section IV. 11.5 Property Ownership/Management The property is currently privately owned and managed by Mr. & Mrs. Dominic Tucci. TUCCI RESIDENCE 20002 -WQMP Page 7 PA2020-016 Water Quality Management Plan (WQMP) 3905 Marcus Avenue, Newport Beach, CA Section III Site Description III.1 Physical Setting Planning Area/ Community Name Newport Island Incorporated Location/ Address 3905 Marcus Avenue, Newport Beach, CA 92663 Project Area Description The subject site is a single-family residential lot located on the west side of Marcus A venue, just north of the intersection with 39th Street. The property is currently developed with a residential building, attached garage, and associated hardscape features such as walkways, patios, concrete driveway, and side yard fences. The project site is bounded on the east by Marcus A venue, on the west by a channel tributary to Lower Newport Bay, and to the north and south by similarly sized residential properties. Land Use RT-D: Two-Unit Residential -(20.0 -29.9 DU/ AC) Zoning R-2: Two-Unit Residential Acreage The site measures 2,857 square feet (0.066 acres). The entire site will be disturbed as a result of this development. The proposed redevelopment results in the addition/replacement of 2,770 sq. ft. of impervious surfaces immediately adjacent to Lower Newport Bay (an ESA). Predominant Soil Type Per the USDA Web Soil Survey, the project is located in an area designated "Beaches". TUCCI RESIDENCE 20002 -WQMP Page 8 PA2020-016 Water Quality Management Plan (WQMP) 3905 Marcus Avenue, Newport Beach, CA 111.2 Site Characteristics Precipitation Zone • Per the Orange County Rainfall Zones Map, the project site is within the rainfall zone with a Design Capture Storm Depth of 0.70 inches. . .... Based upon the site elevations shown on the Precise Grading and Drainage Topography Plan prepared by Toal Engineering, Inc., there is approximately 2' of relief across the development area. . ......... See discussions in Sections II.I and II-4-Existing development area runoff is assumed to percolate into the on-site soils (due to lack of discharge pipes to Drainage street or bay, and no stormwater pump). Post-development runoff is collected Patterns/ Connections and treated on-site, with peak storm volumes discharged off-site to Marcus Avenue. Runoff on Marcus Avenue is then collected by the City storm drain system and discharged to Lower Newport Bay. Soil Type, Geology, and This site is within an area designated "Beaches" by the USDA Web Soil Survey. Infiltration Properties See the 'Geotechnical Conditions' discussion later in Section III.2. Site Characteristics {continued} H ydrogeologic (Groundwater) Conditions Geotechnical Conditions (relevant to infiltration) Off-Site Drainage Utility and Infrastructure Information TUCCI RESIDENCE 20002 -WQMP Per the soils report prepared by R. McCarthy Consulting, Inc. and dated December 30, 2019, "groundwater was encountered at a depth of7 feet", "groundwater levels are anticipated to remain near existing elevations", and that "groundwater is tidal influenced and will fluctuate daily." Per the project soils report, the on-site materials consist of 6-inches ofloose, residual planter soil (brown silty sand), underlain by marine deposits consisting oflight gray brown sand, silty sand, and occasional silt to the maximum explored depth oh feet. Laboratory test results and visual observations indicate that the on-site sands are non-expansive. Per a letter entitled "Proposed Gravel Trench" prepared by Rob McCarthy of R. McCarthy Consulting, Inc., a gravel trench for periodic water infiltration in the driveway area is acceptable provided the trench is at least 3 feet away from garage foundations. See letter provided in Attachment B. The site includes the following perimeter protections to avoid run-on: 1) walls and fences along the side yards and rear yard; and 2) the gutter along Marcus Avenue is a couple feet below the pad grade of the proposed living areas. Service laterals will be taken from utility main lines within the adjacent street and alley rights-of-way.

PA2020-016 Water Quality Management Plan (WQMP) 3905 Marcus Avenue, Newport Beach, CA Section IV Best Management Practices (BMPs) IV. 1 Project Performance Criteria Describe project performance criteria. Several steps must be followed in order to determine what performance criteria will apply to a project. These steps include: • If the project has an approved WIHMP or equivalent, then any watershed specific criteria must be used and the project can evaluate participation in the approved regional or sub- regional opportunities. The local Permittee planning or NPDES staff should be consulted regarding the existence of an approved WIHMP or equivalent. • Determine applicable hydromodification control performance criteria. • Determine applicable LID performance criteria. • Determine applicable treatment control BMP performance criteria. • Calculate the LID design storm capture volume for the project. Is there an approved WIHMP or equivalent for the project area that includes more stringent LID feasibility criteria or if there are opportunities identified for implementing LID on regional or sub- regional basis? If yes, describe WIHMP feasibility criteria or regional/ sub-regional LID opportunities. TUCCI RESIDENCE 20002 -WQMP YES □ NO[2) Page 11 PA2020-016 Water Quality Management Plan (WQMP) 3905 Marcus Avenue, Newport Beach, CA Project Performance Criteria ( continued) If HCOC exists, list applicable hydromodification control performance criteria (Section 7.II-2.4.2.2 in MWQMP) List applicable LID performance criteria (Section 7.II-2.4.3 from MWQMP) List applicable treatment control BMP performance criteria (Section 7.II-3.2.2 from MWQMP) Calculate LID design storm capture volume for Project. TUCCI RESIDENCE 20002 -WQMP For projects that may have an impact on the site's hydrologic regime, an assessment of potential hydromodification impacts and appropriate controls is required. If an HCOC exists, priority projects shall implement on-site or regional hydromodification controls such that: • Post-development runoff volume for the two-year frequency storm does not exceed that of the predevelopment condition by more than five percent, and • Time of concentration of post-development runoff for the two-year storm event is not less than that for the predevelopment condition by more than five percent. • Priority Projects must infiltrate, harvest and use, evapotranspirate, or biotreat/biofilter, the 85th percentile, 24-hour storm event (Design Capture Volume). • A properly designed biotreatment system may only be considered if infiltration, harvest and use, and evapotranspiration (ET) cannot be feasibly implemented for the full design capture volume. In this case infiltration, harvest and use, and ET practices must be implemented to the greatest extent feasible and biotreatment may be provided for the remaining design capture volume. • If treatment control BMPs can treat all of the remaining unmet volume and have a medium to high effectiveness for reducing the primary POCs, the project is considered to be in compliance. • If the cost of providing treatment control BMPs greatly outweighs the pollution control benefits they would provide, a waiver of treatment control and LID requirements can be requested and alternative compliance approaches must be used to fulfill the remaining unmet volume.

SITE DESIGN AND DRAINAGE PLAN The following Site Design Practices have been considered for the proposed residential development: Preserve Existing Drainage Patterns and Time of Concentration ( to the MEP) Minimize Construction Footprint ( construction will be limited to only the area designated for improvements) The proposed site improvements include the residence, driveway, exterior impervious walkways, patios, pool/spa, and landscaping improvements. The construction footprint shall be limited to only the areas designated for improvements per the Precise Grading and Drainage Plans prepared by Toal Engineering, Inc. There is one (1) Drainage Management Areas (DMA) for this single-family residential development. The selected LID BMP will be used to address the water quality design goals for the project DMA: Perforated Drain Trenches (Infiltration BMP) -located in front yard; sizing per City standard. DMA Area (sq. ft.) % Impervious BMPType Size 1 2,857 o.97 HSC-1: Bottomless Trench Drain 21 LF See discussion for the selected BMP in Section IV.3.1. See the WQMP Site Plan provided in Section VI of this report for locations of site improvements and the selected HSC Infiltration BMP. See Section IV.3.1 for sizing calculations related to the HSC Infiltration BMPs. See Water Infiltration letter prepared by R McCarthy Consulting, Inc. in Attachment B. The GIS coordinates for the onsite BMP are: 33.619270, -117.934423. TUCCI RESIDENCE 20002 -WQMP Page 13 PA2020-016 Water Quality Management Plan (WQMP) 3905 Marcus Avenue, Newport Beach, CA IV.3 LID BMP SELECTION AND PROJECT CONFORMANCE ANALYSIS IV.3.1 Hydrologic Source Controls Name Included? Localized on-lot infiltration ~ Impervious area dispersion (e.g. roof top □ disconnection) Street trees (canopy interception) □ Residential rain barrels (not actively managed) □ Green roofs/Brown roofs □ Blue roofs □ Impervious area reduction (e.g. permeable □ pavers, site design) BMP HSC-1 (Localized On-Lot Infiltration) is provided to comply with the City's design criteria for all projects to retain concentrated and surface sheet flow water from dry-weather runoff and minor rain events within the site. The BMP is sized to fully address the water quality design goals for this 0.066-acre single- family residential property. A City-standard perforated drain trench is proposed along the front property line for infiltration of project storm runoff prior to off-site discharge. The perforated drain trench includes a perforated pipe encased in gravel and wrapped in filter fabric, with the gravel area measuring 12'' wide by 18" deep. The City of Newport Beach requires one (1) 15' long perforated drain trench for every 2,000 sq. ft. of impervious surface area. DMA-1 has 2,770 sq. ft. of total impervious area, requiring 20.8 feet of perforated drain trench ((2770/2000) * 15 ft.= 20.8 ft.); 21 lineal feet of perforated drain trench is provided for DMA-1. Per the geotechnical information provided in Section 111.2 (Page 9) of this report, "groundwater was encountered at a depth of7 feet", "groundwater levels are anticipated to remain near existing elevations", and "groundwater is tidal influenced and will fluctuate daily." With -24" max. depth to the bottom of the proposed perforated drain trenches and bottomless trench drains, the separation to minor perched groundwater is -5'. Per the TGD for North Orange County, appropriate infiltration BMPs for 5' minimum separation to groundwater include "dispersion trenches (small, residential applications)."

Refer to Appendix VI I (Worksheet I) for guidance on groundwater-related infiltration feasibility criteria. Provide basis: Yes No X Groundwater is estimated at 7 ft. below the ground surface per the project soils report prepared by R. McCarthy Consulting Inc., thus infiltration measures are limited to surface and shallow infiltration applications for this residential development. 2 Would Infiltration BMPs pose significant risk of increasing risk of geotechnical hazards that cannot be mitigated to an acceptable level? (Yes if the answer to any of the following questions is yes, as established by a geotechnical expert): • The BMP can only be located less than 50 feet away from slopes steeper than 15 percent • The BMP can only be located less than eight feet from building foundations or an alternative setback. • A study prepared by a geotechnical professional or an available watershed study substantiates that stormwater infiltration would potentially result in significantly increased risks of geotechnical hazards that cannot be mitigated to an acceptable level. Provide basis: X Per the "Proposed Gravel Trench" letter prepared by R. McCarthy Consulting, Inc., on-site infiltration measures may be setback 3 feet from building foundations beneath the driveway surface due to the sandy nature of the underlying soils.

Provide basis: The site is within an area designated as "Beaches" per the USDA Web Soil Survey. Per the aforementioned soils report, the on-site materials consist of 6-inches of loose, residual planter soil (brown silty sand), underlain by marine deposits consisting of light gray brown sand, silty sand, and occasional silt to the maximum explored depth of 7 feet. Laboratory test results and visual observations indicate that the on-site sands are non-expansive. Is measured infiltration rate below proposed facility 5 less than 0.3 inches per hour? This calculation shall be N/A based on the methods described in Appendix VII.

Gravel trenches for periodic water infiltration into the on-site soil in the driveway area at 3905 Marcus Avenue are acceptable from a geologic and geotechnical standpoint. The trenches should be at least 3 feet away from the garage foundations. The water levels are expected to be at a depth of about 5 to 7 feet below grade. The water table is ultimately tidal in nature and introduction of the infiltration water is not expected to raise the water level or create new perched water zones. There are permeable silty sand materials down to the depth explored in our investigation. The infiltration from the gravel trenches will, therefore, not create any geohazards due to modification of groundwater levels. If soil-cement treatment is used to stabilize saturated soil zones during grading, the contractor should not cement treat any horizontal layers below the planned gravel trench locations. Gravel and geofabric stabilization methods, if necessary, are an acceptable alternative. The locations of the planned gravel trenches should be clearly marked for the grading contractor and geotechnical consultant with offset perimeter stakes or paint at the start of the earthwork removals. Our office should be notified to observe the construction of the gravel trenches and perforated pipe. Thank you for this opportunity to be of service. If you have any questions, please contact this office. Respectfully submitted, R MCCARTHY CONSUL TING, INC. Robert J.

Hydrologic Source Control Fact Sheets (HSC) HSC-1: Localized On-Lot Infiltration 'Localized on-lot infilh·ation' refers to the practice of collecting on-site runoff from small distributed areas within a catchment and diverting it to a dedicated on-site infiltration area. This tecluuque can include disc01mecting downspouts and draining sidewalks and patios into french drains, trenches, small rain gardens, or other surface depressions. For downspout disconnections and other impervious area disco1mection involving dispersion over pervious surfaces, but without intentional ponding, see HSC-2: Impervious Area Dispersion. Feasibility Screening Considerations • 'Localized on-lot infiltration' shall meet infiltration infeasibility screening criteria to be considered for use. Opportunity Criteria • Runoff can be directed to and temporarily pond in pervious area depressions, rock trenches, or similar. Also known as: ► Downspout infiltration ► Retention grading ► French drains ► On-lot rain gardens On-lot rain garden Source: lowimpactdevelopment. org • Soils are adequate for infiltration or can be amended to provide an adequate infiltration rate. • Shallow utilities are not present below infiltration areas. DC-Specific Design Criteria and Considerations □ □ □ □ □ □ □ □ A single on-lot infiltration area should not be sized to retain runoff from impervious areas greater than 4,000 sq. ft.; if the drainage area exceeds this criteria, sizing should be based on calculations for bioretention areas or infiltration trenches. Soils should be sufficiently permeable to eliminate ponded water within 24 hours following a 85th percentile, 24-hour storm event. Maximum ponding depth should be should be less than 3 inches and trench depth should be less than 1.5 feet. Infiltration should not be used when the depth to the mounded seasonally high table is within 5 feet of the bottom of infiltrating surface. Infiltration via depression storage, trench drains, or rain gardens should be located greater than 8 feet from building foundations. Site slope should be less than 10%. Infiltration unit should not be located within 50 feet of slopes greater than 15 percent. Side slopes of rain garden or depression storage should not exceed 3H :1V. D Effective energy dissipation and uniform flow spreading methods should be employed to prevent erosion resulting fromwater entering infiltration areas.

General Landscaping Tips ■ Protect stockpiles and materials from wind and rain by storing them under tarps or secured plastic sheeting. ■Prevent erosion of slopes by planting fast-growing, dense ground covering plants. These will shield and bind the soil. ■Plant native vegetation to reduce the amount of water, fertilizers, and pesticide applied to the landscape. ■ ever apply pesticides or fertilizers when rain is predicted .vithin the next 48 hours. Garden & Lawn Maintenance ■Do not overwater. Use irrigation practices such as drip irrigation, soaker hoses or micro spray systems. Periodically inspect and fix leaks and misdirected sprinklers. ■ Do not rake or blow leaves, clippings or pruning waste into the street, g·utter or storm drain. Instead, dispose of green waste by composting, hauling it to a permitted landfill, or recycling it through your city's program. ■ Use slow-release fertilizers to minimize leaching, and use organic fertilizers. ■ Read labels and use only as directed. Do not over-apply pesticides or fertilizers. Apply to spots as needed, rather than blanketing an entire area. ■ Store pesticides, fertilizers and other chemicals in a dry covered area to prevent exposure that may result , in the deterioration of containers and packaging. ■ Rinse empty pesticide containers and re-use rinse water as you would use the product. Do not dump rinse water down storm drains. Dispose of empty containers in the trash. ■When available, use non-toxic alternatives to traditional pesticides, and use pesticides specifically designed to control the pest you are targeting. For more information, visit ·www.ipm.ucdavis.edu. ■ If fertilizer is spilled, sweep up the spill before irrigating. If the spill is liquid, apply an absorbent mate1ial such as cat litter, and then sweep it up and dispose of it in the trash. ■ Take unwanted pesticides to a Household Hazardous v\Taste Collection Center to be recycled.

IDne Ocean Begins at Your Front Door PROJECT Poi~ut,on ., PA2020-016Many pools are plumbed to allow the pool to drain directly to the sanitary sewer. If yours is not, follow these instructions for disposing of pool and spa water. Acceptable and Preferred Method of Disposal When you cannot dispose of pool water in the sanitary sewer, the release of dechlorinated s,vimming pool water is allowed if all of these tips are followed: ■The residual chlorine does not exceed 0.1 mg/1 (parts per million). ■The pH is between 6.5 and 8.5. ■The water is free of any unusual coloration, dirt or algae. ■There i no discharge of filter media. ■There is no discharge of acid cleaning wastes. ■ Some cities may have ordinances that do not allow pool water to be disposed into a storm drain. Check with your city. How to Know if You 're Following the Standards You can find out how much chlorine is in your water by using a pool testing kit. Excess chlorine can be removed by discontinuing the use of chlorine for a few days prior to discharge or by purchasing dechlorinating chemicals from a local pool supply company. Always make sure to follow the instructions that come with any products you use. Doing Your Part By complying \vi.th these guidelines, you \vi.11 make a significant contribution toward keeping pollutants out of Orange County's creeks, streams, rivers, bays and the ocean. This helps to protect organisms that are sensitive to pool chemicals, and helps to maintain the health of our environment. PROJ[(T Po~hd,011
