The project Precise Grading Plan shows the proposed grading, site improvements, and retaining walls necessary for construction of a single-family residence. Site Design Practices The project incorporates Site Design practices as follows: • Preserve Existing Drainage Patterns and Time of Concentration – The ultimate points of discharge are the same for the pre- and post-project conditions. Time of concentration will be similar, since pre-and post-project flow path lengths will be similar. Drainage Management Areas (DMAs) The site has two Drainage Management Areas. Drainage from DMA-1 & DMA-2 is directed into a shared infiltration trench at the front of the property. Storm flows exceeding the trench capacity will be discharged to Via Lido Soud. All roof runoff will be pre-treated by a downspout filter (TRT-2) prior to being discharged into the infiltration BMPs.

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) Other: Hydrologic Source Controls have not been used due to space constraints, including landscape area size and proximity to structure foundations. PA2019-142 Water Quality Management Plan (WQMP) Campbell Residence – 605 Via Lido Soud, Newport Beach, California MS. BRIDGET CAMPBELL Section IV Page 14 IV.3.2 Infiltration BMPs Infiltration BMPs to be used for this project are indicated in the table below. Implementation of said controls is discussed in the text that follows. Name Included? Bioretention without underdrains Rain gardens Porous landscaping Infiltration planters Retention swales Infiltration trenches Infiltration basins Drywells Subsurface infiltration galleries French drains Permeable asphalt Permeable concrete Permeable concrete pavers Other: The sizing has been done per the City of Newport Beach’s prescriptive requirements of “One 15’ long French drain per maximum of 2,000 sf of impervious area”. The sizing for each DMA is: DMA-1: Area tributary to BMP = 1,800 s.f. Gravel Volume within City’s 15’ Long Trench Drain = 15’L x 12”W x 12”D = 15 c.f. Sizing for infiltration gravel = 1,800 s.f. x (15 c.f./2,000 s.f.) = 13.5 c.f. (min. volume) gravel area DMA-2: Area tributary to BMP = 1,584 s.f. Gravel Volume within City’s 15’ Long Trench Drain = 15’L x 12”W x 12”D = 15 c.f. Sizing for infiltration gravel = 1,584 s.f. x (15 c.f./2,000 s.f.) = 11.9 c.f. (min. volume) gravel area SHARED INFILTRATION TRENCH FOR DMA-1 & DMA-2: Provided Gravel Volume per Site Plan = 18” wide x 12” deep x 30’ long trench = 45 c.f. 13.5 c.f. + 11.9 c.f. = 25.4 c.f. < 45 c.f.

BRIDGET CAMPBELL Section IV Page 15 Table 2.7: Infiltration BMP Feasibility Worksheet Infeasibility Criteria Yes No 1 Would Infiltration BMPs pose significant risk for groundwater related concerns? Refer to Appendix VII (Worksheet I) for guidance on groundwater-related infiltration feasibility criteria. X Provide basis: Infiltration BMPs will not pose a significant risk to local groundwater. Groundwater in the vicinity of the project site is not used for drinking water. Pretreatment devices will mitigate entry of trash, sediment, and oil & grease into proposed infiltration BMPs. 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. X Provide basis: 3 Would infiltration of the DCV from drainage area violate downstream water rights? X Provide basis: There are no downstream water right holders since site drainage is conveyed via the city storm drain system directly to receiving waters (Lower Newport Bay).

BRIDGET CAMPBELL Section IV Page 16 Table 2.7: Infiltration BMP Feasibility Worksheet (continued) Partial Infeasibility Criteria Yes No 4 Is proposed infiltration facility located on HSG D soils or the site geotechnical investigation identifies presence of soil characteristics which support categorization as D soils? X Provide basis: Proposed facility is located on HSG-A soils per OCHM Soil Maps. 5 Is measured infiltration rate below proposed facility less than 0.3 inches per hour? This calculation shall be based on the methods described in Appendix VII. X Provide basis: Infiltration rate is presumed to be greater than 0.3 inches per hour based on site’s HSG. 6 Would reduction of over predeveloped conditions cause impairments to downstream beneficial uses, such as change of seasonality of ephemeral washes or increased discharge of contaminated groundwater to surface waters? X Provide citation to applicable study and summarize findings relative to the amount of infiltration that is permissible: No downstream beneficial uses such as ephemeral washes or groundwater sources of drinking water are located downstream of the subject property. 7 Would an increase in infiltration over predeveloped conditions cause impairments to downstream beneficial uses, such as change of seasonality of ephemeral washes or increased discharge of contaminated groundwater to surface waters? X Provide citation to applicable study and summarize findings relative to the amount of infiltration that is permissible: No downstream beneficial uses such as ephemeral washes or groundwater sources of drinking water are located downstream of the subject property.

(See Appendix XVII) Provide narrative discussion and supporting evidence: No evidence of I&I has been provided by the local sewer agency (City of Newport Beach). No 9 If any answer from row 1-3 is yes: infiltration of any volume is not feasible within the DMA or equivalent. Provide basis: 10 If any answer from row 4-8 is yes, infiltration is permissible but is not presumed to be feasible for the entire DCV. Criteria for designing biotreatment BMPs to achieve the maximum feasible infiltration and ET shall apply. Provide basis: 11 If all answers to rows 1 through 10 are no, infiltration of the full DCV is potentially feasible, BMPs must be designed to infiltrate the full DCV to the maximum extent practicable.

Refer to Section 7.II-3.1 in the Model WQMP. Calculate the amount of remaining obligation that must be met with alternative compliance (See TGD Appendix VI). IV.4.2 Water Quality Credits Determine if water quality credits are applicable for the project. Refer to Section 7.II-3.2 of the Model WQMP for description of credits and TGD Appendix VI for calculation methods for applying WQ credits. Description of Proposed Project Project Types that Qualify for Water Quality Credits (Select all that apply): Redevelopment projects that reduce the overall impervious footprint of the project site. Brownfield redevelopment, meaning redevelopment, expansion, or reuse of real property which may be complicated by the presence or potential presence of hazardous substances, pollutants or contaminants, and which have the potential to contribute to adverse ground or surface WQ if not redeveloped. Higher density development projects which include two distinct categories (credits can only be taken for one category): those with more than seven units per acre of development (lower credit allowance); vertical density developments, for example, those with a Floor to Area Ratio (FAR) of 2 or those having more than 18 units per acre (greater credit allowance). Mixed use development, such as a combination of residential, commercial, industrial, office, institutional, or other land uses which incorporate design principles that can demonstrate environmental benefits that would not be realized through single use projects (e.g. reduced vehicle trip traffic with the potential to reduce sources of water or air pollution). Transit-oriented developments, such as a mixed use residential or commercial area designed to maximize access to public transportation; similar to above criterion, but where the development center is within one half mile of a mass transit center (e.g. bus, rail, light rail or commuter train station). Such projects would not be able to take credit for both categories, but may have greater credit assigned Redevelopment projects in an established historic district, historic preservation area, or similar significant city area including core City Center areas (to be defined through mapping). Developments with dedication of undeveloped portions to parks, preservation areas and other pervious uses. Developments in a city center area. Developments in historic districts or historic preservation areas. Live-work developments, a variety of developments designed to support residential and vocational needs together – similar to criteria to mixed use development; would not be able to take credit for both categories. In-fill projects, the conversion of empty lots and other underused spaces into more beneficially used spaces, such as residential or commercial areas. Calculation of Water Quality Credits (if applicable) This project does not qualify for the water quality credits listed above.

Runoff is stored in the void space between stones and infiltrates through the bottom and sides of the trench. Infiltration trenches provide the majority of their pollutant removal benefits through volume reduction. Pretreatment is important for limiting amounts of coarse sediment entering the trench which can clog and render the trench ineffective. Note: if an infiltration trench is “deeper than its widest surface dimension,” or includes an assemblage of perforated pipes, drain tiles, or other similar mechanisms intended to distribute runoff below the surface of the ground, it would probably be considered a "Class V Injection Well" under the federal Underground Injection Control (UIC) Program, which is regulated in California by U.S. EPA Region 9. A UIC permit may be required for such a facility (for details see http://www.epa.gov/region9/water/groundwater/uic-classv.html). Feasibility Screening Considerations x Infiltration trenches shall pass infeasibility screening criteria to be considered for use x Infiltration trenches, particularly deeper designs, may not provide significant attenuation of stormwater pollutants if underlying soils have high permeability; potential risk of groundwater contamination. x The potential for groundwater mounding should be evaluated if depth to seasonally high groundwater (unmounded) is less than 15 feet. Opportunity Criteria x Soils are adequate for infiltration or can be amended to provide an adequate infiltration rate. x Drainage area area is ≤ 5 acres and has low to moderate sediment production. x 2-3 percent of drainage area available for infiltration (generally requires less surface area than infiltration basins and bioretention areas without underdrain). x Space available for pretreatment (biotreatment or treatment control BMP as described below). x Potential for groundwater contamination can be mitigated through isolation of pollutant sources, pretreatment of inflow, and/or demonstration of adequate treatment capacity of underlying soils. x Infiltration is into native soil, or depth of engineered fill is ≤ 5 feet from the bottom of the facility to native material and infiltration into shallow fill is approved by a geotechnical professional. x Tributary area land uses include open areas adjacent to parking lots, driveways, and buildings, and roadway medians and shoulders. OC-Specific Design Criteria and Considerations □ Must comply with local, state, and federal UIC regulations if applicable; a permit may be required. Also known as: ¾French Drains ¾Rock Trenches ¾Exfiltration Trenches ¾Soak-aways ¾Soakage Trenches Infiltration Trench Source: www.dot.ca.gov PA2019-142 TECHNICAL GUIDANCE DOCUMENT APPENDICES XIV-25 December 20, 2013 □ Placement of BMPs should observe geotechnical recommendations with respect to geological hazards (e.g. landslides, liquefaction zones, erosion, etc.) and set -backs (e.g., foundations, utilities, roadways, etc.) □ For facilities with tributary area less than 1 acre and less than 3 foot depth, minimum separation to mounded seasonally high groundwater of 5 feet shall be observed. □ For facilities with tributary area greater than 1 acre or deeper than 3 feet, minimum separation to mounded seasonally high groundwater of 10 feet shall be observed. □ Minimum pretreatment should be provided upstream of the infiltration trench, and water bypassing pretreatment should not be directed to the infiltration trench. □ Infiltration trenches should not be used for drainage areas with high sediment production potential unless preceded by full treatment control with a BMP effective for sediment removal. □ Ponded water should not persist within 1 foot of the surface of the facility for longer than 72 hours following the end of a storm event (observation well is needed to allow observation of drain time). □ Energy dissipators should be provided at inlet and outlet to prevent erosion. □ An overflow device must be provided if basin is on-line. □ A minimum freeboard of one foot should be provided above the overflow device (f or an on-line basin) or the outlet (for an off-line basin). □ Longitudinal trench slope should not exceed 3%. □ Side slopes above trench fill should not be steeper than 3:1. Simple Sizing Method for Infiltration Trenches If the Simple Design Capture Volume Sizing Method is used to size an infiltration trench, the user calculates the DCV and then designs the geometry required to draw down the DCV in 48 hours. The sizing steps are as follows: Step 1: Determine Infiltration Basin DCV Calculate the DCV using the Simple Design Capture Volume Sizing Method described in Appendix III.3.1. Step 2: Determine the 48-hour Effective Depth The depth of water that can be drawn down in 48 hours can be calculated using the following equation: d48 = KDESIGN × SACF × 48 hours Where: d48 = trench effective 48-hour depth, ft KDESIGN = basin design infiltration rate, in/hr (See Appendix VII) SACF = Surface Area Correction Factor = ranges from 1.0 (sides insignificant or not accounted) to 2.0 (sides plus bottom are 2 times the surface area of the bottom at mid depth) to account for the ratio of infiltration through the sides of the trench to the bottom footprint of the trench; should be based on anticipated trench geometry and wetted surface area at mid-depth. This is the maximum effective depth of the trench below the overflow device to achieve drawdown in 48 hours. PA2019-142 TECHNICAL GUIDANCE DOCUMENT APPENDICES XIV-26 December 20, 2013 Step 3: Determine the Trench Ponding Depth and Trench Depth The depth of water stored in the ponding depth (i.e. above the trench fill) and within the trench itself should be equal or less than d48. Determine the ponding depth and the trench fill depth such that: d48 ≥ (nT × dT + dP) Where: d48 = trench effective 48-hour depth, ft (from Step 2) nT = porosity of trench fill; 0.35 may be assumed where other information is not available dT = depth of trench fill, ft dP = ponding depth, ft (should not exceed 1 ft) Step 4: Calculate the Required Infiltrating Area The required footprint area can be calculated using the following equation: A = DCV/ ((nT × dT) + dP) Where: A = required trench footprint area, sq-ft DCV = design capture volume, cu-ft (see Step 1) nT = porosity of trench fill; 0.35 may be assumed where other information is not available dT = depth of trench fill, ft dP = ponding depth, ft Capture Efficiency Method for Infiltration Trenches If BMP geometry has already been defined and deviates from the 48 hour drawdown time, the designer can use the Capture Efficiency Method for Volume-Based, Constant Drawdown BMPs (Appendix III.3.2) to determine the fraction of the DCV that must be provided to manage 80 percent of average annual runoff volume. This method accounts for drawdown time different than 48 hours. Step 1: Determine the drawdown time associated with the selected trench geometry DD = ((nT × dT) + dP) / (KDESIGN × SACF) × 12 Where: DD = time to completely drain infiltration basin ponding depth, hours nT = porosity of trench fill; 0.35 may be assumed where other information is not available dT = depth of trench fill, ft dP = ponding depth, ft SACF = Surface Area Correction Factor = ranges from 1.0 (sides insignificant or not accounted) to 2.0 (sides plus bottom are 2 times the surface area of the bottom at mid depth) to account for the ratio of infiltration through the sides of the trench to the bottom footprint of the trench; should be based on anticipated trench geometry and wetted surface area at mid-depth. KDESIGN = basin design infiltration rate, in/hr (See Appendix VII) Step 2: Determine the Required Adjusted DCV for this Drawdown Time Use the Capture Efficiency Method for Volume-Based, Constant Drawdown BMPs (Appendix III.3.2) to calculate the required fraction of the DCV the basin must hold to achieve 80 percent capture of average annual stormwater runoff volume based on the trench drawdown time calculated above. PA2019-142 TECHNICAL GUIDANCE DOCUMENT APPENDICES XIV-27 December 20, 2013 Step 3: Determine the Trench Infiltrating Area Needed The required footprint area can be calculated using the following equation: A = DCV / ( (nT × dT) + dP) Where: A = required trench footprint area, sq-ft DCV = design capture volume, cu-ft (see Step 1) nT = porosity of trench fill; 0.35 may be assumed where other information is not available dT = depth of trench fill, ft dP = ponding depth, ft If the area required is greater than the selected trench area, adjust surface area or adjust ponding and/or trench depth and recalculate required area until the required area is achieved. Configuration for Use in a Treatment Train x Infiltration trenches may be preceeded in a treatment train by HSCs in the drainage area, which would reduce the required volume of the trench. x Infiltration trenches must be preceeded by some form of pretreatment which may be biotreatment or a treatment control BMP; if an approved biotreatment BMP is used as pretreatment, the overflow from the infiltration trench may be considered “biotreated” for the purposes of meeting the LID requirments x The overflow or bypass from an infiltration trench can be routed to a downstream biotreatment BMP and/or a treatment control BMP if additional control is required to achieve LID or treatment control requirements Additional References for Design Guidance x CASQA BMP Handbook for New and Redevelopment: http://www.cabmphandbooks.com/Documents/Development/TC-10.pdf x SMC LID Manual (pp 141): http://www.lowimpactdevelopment.org/guest75/pub/All_Projects/SoCal_LID_Manual/SoCalL ID_Manual_FINAL_040910.pdf x Los Angeles County Stormwater BMP Design and Maintenance Manual, Chapter 6: http://dpw.lacounty.gov/DES/design_manuals/StormwaterBMPDesignandrainage areaintenance.pdf x City of Portland Stormwater Management Manual (Soakage Trenches, page 2-82) http://www.portlandonline.com/bes/index.cfm?c=47954&a=202883 x San Diego County LID Handbook Appendix 4 (Factsheet 1): http://www.sdcounty.ca.gov/dplu/docs/LID-Appendices.pdf PA2019-142 TECHNICAL GUIDANCE DOCUMENT APPENDICES XIV-74 December 20, 2013 TRT-2: Cartridge Media Filter Cartridge media filters (CMFs) are manufactured devices that consist of a series of modular filters packed with engineered media that can be contained in a catch basin, manhole, or vault that provide treatment through filtration and sedimentation. The manhole or vault may be divided into multiple chambers where the first chamber acts as a pre- settling basin for removal of coarse sediment while another chamber acts as the filter bay and houses the filter cartridges. A variety of media types are available from various manufacturers which can target pollutants of concern. Feasibility Screening Considerations x Not applicable Opportunity Criteria x Intended for use when retention and biotreatment options are infeasible. x Recommended for drainage area with limited available surface area or where surface BMPs would restrict uses. x For drainage areas with significant areas of non-stabilized soil, permanent soil stablization must be achieved before before cartridge media filters are installed and put on line to minimize risk of clogging. x Depending on the number of cartridges, maintenance events can have long durations. Care should be exercised in siting these facilities so that maintenance events will not significantly disrupt businesses or traffic. OC-Specific Design Criteria and Considerations □ Cartridge media filter BMP vendors should be consulted regarding design and specifications. □ Filter media should be selected to target pollutants of concern. A combination of media may be appropriate to remove a variety of pollutants. □ If CMF are integrated with a vault for equalization, the system should be designed to completely drain the vault within 96 hours of storm event or otherwise protect aga inst standing water and mosquito breeding concerns. Computing Sizing Criteria for Cartridge Media Filters The required design flowrate should be calculated based on the Capture Efficiency Method for Flow- based BMPs (See Appendix III.3.3).

General Landscaping Tips • Protect stockpiles and materials from wind and rain by storing them under tarps or secured plastic sheeting. •Prevent erosion of slopes b y planting fast-growing, dense ground covering plants. These will shield and bind the soil. •Plant native vegetation to reduce the amount of water, fertili zers, and pesticide applied to the landscape. •Never apply pesticides or fertilizers when rain is predicted within 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, gutter 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 fertili zers. • 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 i n the trash. •When available, use non-toxic alternatives to traditional pesticides, and use pesticides specifi cally designed to control the pest you are targeting. For more information, visit www.ipm.ucdavis.edu. • If fertilizer is spilled, sweep up th e spill before irrigating. If the spill is liquid, apply an absorbent material such as cat litter, and then sweep i t up and dispose of i t in the trash. • Take unwanted pesticides to a Household Hazardous Waste Collection Center to be recycled.

Tli e Ocean Begins at Your Front Door PROJECT Poii~t,on _P R E V E N ,T-I O N PA2019-142 Many 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. f Acceptable and Preferred Method of Disposal When you cannot dispose of pool water in the sanitary sewer, the release of dechlorinated swimming 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 is 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 t o 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 l ocal pool supply company. Always make sure to follow the instructi ons that come with any products you use. Doi ng Your Part By complying with these guidelines, you will 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.
