To view the BMP Manual, refer to the Engineering Standards (Volume 5). This questionnaire must be completed by the applicant in advance of submitting for a development application (subdivision, discretionary permits and/or construction permits). The results of the questionnaire determine the level of storm water standards that must be applied to a proposed development or redevelopment project. Depending on the outcome, your project will either be subject to 'STANDARD PROJECT' requirements or be subject to 'PRIORITY DEVELOPMENT PROJECT' (PDP) requirements. Your responses to the questionnaire represent an initial assessment of the proposed project conditions and impacts. City staff has responsibility for making the final assessment after submission of the development application. If staff determines that the questionnaire was incorrectly filled out and is subject to more stringent storm water standards than initially assessed by you, this will result in the return of the development application as incomplete. In this case, please make the changes to the questionnaire and resubmit to the city. If you are unsure about the meaning of a question or need help in determining how to respond to one or more of the questions, please seek assistance from Land Development Engineering staff. A completed and signed questionnaire must be submitted with each development project application. Only one completed and signed questionnaire is required when multiple development applications for the same project are submitted concurrently.

E-36 Page 4 of 4 Revised 09/16 Waste Handling & Disposal Description Improper storage and handling of solid wastes can allow toxic compounds, oils and greases, heavy metals, nutrients, suspended solids, and other pollutants to enter stormwater runoff. The discharge of pollutants to stormwater from waste handling and disposal can be prevented and reduced by tracking waste generation, storage, and disposal; reducing waste generation and disposal through source reduction, reuse, and recycling; and preventing run-on and runoff. Approach Pollution Prevention ■ Accomplish reduction in the amount of waste generated using the following source controls: Production planning and sequencing Process or equipment modification Raw material substitution or elimination Loss prevention and housekeeping Waste segregation and separation Close loop recycling ■ Establish a material tracking system to increase awareness about material usage. This may reduce spills and minimize contamination, thus reducing the amount of waste produced. ■ Recycle materials whenever possible.

If waste is not in containers, cover all waste piles (plastic tarps are acceptable coverage) and prevent stormwater run-on and runoff with a berm. The waste containers or piles must be covered except when in use. ■ Use drip pans or absorbent materials whenever grease containers are emptied by vacuum trucks or other means. Grease cannot be left on the ground. Collected grease must be properly disposed of as garbage. ■ Check storage containers weekly for leaks and to ensure that lids are on tightly. Replace any that are leaking, corroded, or otherwise dete1iorating. ■ Sweep and clean the storage area regularly. If it is paved, do not hose down the area to a storm drain. ■ Dispose of rinse and wash water from cleaning waste containers into a sanitary sewer if allowed by the local sewer authority. Do not discharge wash water to the street or storm drain. ■ Transfer waste from damaged containers into safe containers. ■ Take special care when loading or unloading wastes to minimize losses. Loading systems can be used to minimize spills and fugitive emission losses such as dust or mist. Vacuum transfer systems can minimize waste loss. Controlling Litter ■ Post "No Littering" signs and enforce anti-litter laws. ■ Provide a sufficient number of litter receptacles for the facility. ■ Clean out and cover litter receptacles frequently to prevent spillage. Waste Collection ■ Keep waste collection areas clean. ■ Inspect solid waste containers for structural damage regularly. Repair or replace damaged containers as necessary. ■ Secure solid waste containers; containers must be closed tightly when not in use. ■ Do not fill waste containers with washout water or any other liquid. ■ Ensure that only appropriate solid wastes are added to the solid waste container. Certain wastes such as hazardous wastes, appliances, fluorescent lamps, pesticides, etc., may not be disposed of in solid waste containers (see chemical/ hazardous waste collection section below). 2 of 5 California Stormwater BMP Handbook Industrial and Commercial www .ca bm phand boo ks.com January 2003 Waste Handling & Disposal SC-34 ■ Do not mix wastes; this can cause chemical reactions, make recycling impossible, and complicate disposal. Good Housekeeping ■ Use all of the product before disposing of the container. ■ Keep the waste management area clean at all times by sweeping and cleaning up spills immediately. ■ Use dry methods when possible (e.g., sweeping, use of absorbents) when cleaning around restaurant/food handling dumpster areas. If water must be used after sweeping/using absorbents, collect water and discharge through grease interceptor to the sewer. Chemical/Hazardous Wastes ■ Select designated hazardous waste collection areas on-site. ■ Store hazardous materials and wastes in covered containers and protect them from vandalism. ■ Place hazardous waste containers in secondary containment. ■ Make sure that hazardous waste is collected, removed, and disposed of only at authorized disposal areas. ■ Stencil or demarcate storm drains on the facility's property with prohibitive message regarding waste disposal. Run-on/Runoff Prevention ■ Prevent stormwater run-on from entering the waste management area by enclosing the area or building a berm around the area. ■ Prevent waste materials from directly contacting rain. ■ Cover waste piles with temporary covering material such as reinforced tarpaulin, polyethylene, polyurethane, polypropyleneor hypalon. ■ Cover the area with a permanent roof if feasible. ■ Cover dumpsters to prevent rain from washing waste out of holes or cracks in the bottom of the dump st er. ■ Move the activity indoor after ensuring all safety concerns such as fire hazard and ventilation are addressed. Inspection ■ Inspect and replace faulty pumps or hoses regularly to minimize the potential of releases and spills. ■ Check waste management areas for leaking containers or spills. January 2003 California Stormwater BMP Handbook Industrial and Commercial www.cabmphandbooks.com 3 of 5 SC-34 Waste Handling & Disposal ■ Repair leaking equipment including valves, lines, seals, or pumps promptly. Training ■ Train staff in pollution prevention measures and proper disposal methods. ■ Train employees and contractors in proper spill containment and cleanup. The employee should have the tools and knowledge to immediately begin cleaning up a spill should one occur. ■ Train employees and subcontractors in proper hazardous waste management. Spill Response and Prevention ■ Keep your Spill Prevention Control and Countermeasure (SPCC) Plan up-to-date. ■ Have an emergency plan, equipment and trained personnel ready at all times to deal immediately with major spills ■ Collect all spilled liquids and properly dispose of them. ■ Store and maintain appropriate spill cleanup materials in a location known to all near the designated wash area. ■ Ensure that vehicles transporting waste have spill prevention equipment that can prevent spills during transport. Spill prevention equipment includes: Vehicles equipped with baffles for liquid waste Trucks with sealed gates and spill guards for solid waste Other Considerations (Limitations and Regulations) Hazardous waste cannot be reused or recycled; it must be disposed of by a licensed hazardous waste hauler. Requirements Costs Capital and O&M costs for these programs will vary substantially depending on the size of the facility and the types of waste handled. Costs should be low if there is an inventory program in place. Maintenance ■ None except for maintaining equipment for material tracking program. Supplemental Information Further Detail of the BMP Land Treatment System Minimize runoff of polluted stormwater from land application by: ■ Choosing a site where slopes are under 6%, the soil is permeable, there is a low wat er table, it is located away from wetlands or marshes, and there is a closed drainage system 4 of 5 California Stormwater BMP Handbook Industrial and Commercial www .cabmphandbooks.com January 2003 Waste Handling & Disposal SC-34 ■ Avoiding application of waste to the site when it is raining or when the ground is saturated with water ■ Growing vegetation on land disposal areas to stabilize soils and reduce the volume of surface water runoff from the site ■ Maintaining adequate barriers between the land application site and the receiving waters (planted strips are particularly good) ■ Using erosion control techniques such as mulching and matting, filter fences, straw bales, diversion terracing, and sediment basins ■ Performing routine maintenance to ensure the erosion control or site stabilization measures are working Examples The port of Long Beach has a state-of-the-art database for identifying potential pollutant sources, documenting facility management practices, and tracking pollutants.

Utilizing the protocols in this fact sheet will prevent or reduce the discharge of pollutants to stormwater from building and grounds maintenance activities by washing and cleaning up with as little water as possible, following good landscape management practices, preventing and cleaning up spills immediately, keeping debris from entering the storm drains, and maintaining the stormwater collection system. Approach Reduce potential for pollutant discharge through source control pollution prevention and BMP implementation. Successful implementation depends on effective training of employees on applicable BMPs and general pollution prevention strategies and objectives. Pollution Prevention ■ Switch to non-toxic chemicals for maintenance when possible. ■ Choose cleaning agents that can be recycled. ■ Encourage proper lawn management and landscaping, including use of native vegetation.

Suggested Protocols Pressure Washing of Buildings, Rooftops, and Other Large Objects ■ In situations where soaps or detergents are used and the surrounding area is paved, pressure washers must use a water collection device that enables collection of wash water and associated solids. A sump pump, wet vacuum or similarly effective device must be used to collect the runoff and loose materials. The collected runoff and solids must be disposed of properly. ■ If soaps or detergents are not used, and the surrounding area is paved, wash runoff does not have to be collected but must be screened. Pressure washers must use filter fabric or some other type of screen on the ground and/or in the catch basin to trap the particles in wash water runoff. ■ If you are pressure washing on a grassed area (with or without soap), runoff must be dispersed as sheet flow as much as possible, rather than as a concentrated stream. The wash runoff must remain on the grass and not drain to pavement. Landscaping Activities ■ Dispose of grass clippings, leaves, sticks, or other collected vegetation as garbage, or by composting. Do not dispose of collected vegetation into waterways or storm drainage systems. ■ Use mulch or other erosion control measures on exposed soils. Building Repair, Remodeling, and Cons truction ■ Do not dump any toxic substance or liquid waste on the pavement, the ground, or toward a st orm drain. ■ Use ground or drop cloths underneath outdoor painting, scraping, and sandblasting work, and properly dispose of collected material daily. ■ Use a ground cloth or oversized tub for activities such as paint mixing and tool cleaning. ■ Clean paintbrushes and tools covered with water-based paints in sinks connected to sanitary sewers or in portable containers that ca.n be dumped into a sanitary sewer drain. Brushes and tools covered with non-water-based paints, finishes, or other materials must be cleaned in a manner that enables collection of used solvents (e.g., paint thinner, turpentine, etc.) for recycling or proper disposal. ■ Use a storm drain cover, filter fabric, or similarly effective runoff control mechanism if dust, grit, wash water, or other pollutants may escape the work area and enter a catch basin. This is particularly necessary on rainy days. The containment device(s) must be in place at the beginning of the work day, and accumulated ditty runoff and solids must be collected and disposed of before removing the containment device(s) at the end of the work day. 2 of 5 California Stormwater BM P Handbook Industrial and Commercial www .cabmphandbooks.com January 2003 Building & Grounds Maintenance SC-41 ■ If you need to de-water an excavation site, you may need to filter the water before discharging to a catch basin or off-site. If directed off-site, you should direct the water through hay bales and filter fabric or use other sediment filters or traps. ■ Store toxic material under cover during precipitation events and when not in use. A cover would include tarps or other temporary cover material. Mowing, Trimming, and Planting ■ Dispose of leaves, sticks, or other collected vegetation as garbage, by composting or at a permitted landfill. Do not dispose of collected vegetation into waterways or storm drainage systems. ■ Use mulch or other erosion control measures when soils are exposed. ■ Place temporarily stockpiled material away from watercourses and drain inlets, and berm or cover stockpiles to prevent material releases to the storm drain system. ■ Consider an alternative approach when bailing out muddy water: do not put it in the storm drain; pour over landscaped areas. ■ Use hand weeding where practical. Fertilizer and Pesticide Management ■ Follow all federal, state, and local laws and regulations governing the use, storage, and disposal of fertilizers and pesticides and training of applicators and pest control advisors. ■ Use less toxic pesticides that will do the job when applicable. Avoid use of copper-based pesticides if possible. ■ Do not use pesticides if rain is expected. ■ Do not mix or prepare pesticides for application near storm drains. ■ Use the minimum amount needed for the job. ■ Calibrate fertilizer distributors to avoid excessive application. ■ Employ techniques to minimize off-target application (e.g., spray drift) of pesticides, including consideration of alternative application techniques. ■ Apply pesticides only when wind speeds are low . ■ Fertilizers should be worked into the soil rather than dumped or broadcast onto the surface. ■ Irrigate slowly to prevent runoff and then only as much as is needed. ■ Clean pavement and sidewalk if fertilizer is spilled on these surfaces before applying irrigation water. ■ Dispose of empty pesticide containers according to the instructions on the container label. January 2003 California Stormwater BMP Handbook Industrial and Commercial www .cabmphandbooks.com 3 of 5 SC-41 Building & Grounds Maintenance ■ Use up the pesticides. Rinse containers, and use rinse water as product. Dispose of unused pesticide as hazardous waste. ■ Implement storage requirements for pesticide products with guidance from the local fire department and County Agricultural Commissioner. Provide secondary containment for pesticides. Inspection ■ Inspect irrigation system periodically to ensure that the right amount of water is being applied and that excessive runoff is not occurring. Minimize excess watering and repair leaks in the irrigation system as soon as they are observed. Training ■ Educate and train employees on pesticide use and in pesticide application techniques to prevent pollution. ■ Train employees and contractors in proper techniques for spill containment and cleanup. ■ Be sure the frequency of training takes into account the complexity of the operations and the nature of the staff. Spill Response and Prevention ■ Keep your Spill Prevention Control and Countermeasure (SPCC) Plan up-to-date. ■ Place a stockpile of spill cleanup materials, such as brooms, dustpans, and vacuum sweepers (if desired) near the storage area where it will be readily accessible. ■ Have employees trained in spill containment and cleanup present during the loading/unloading of dangerous wastes, liquid chemicals, or other materials. ■ Familiarize employees with the Spill Prevention Control and Countermeasure Plan. ■ Clean up spills immediately. Other Considerations Alternative pest/weed controls may not be available, suitable, or effective in many cases. Requirements Costs ■ Cost will vary depending on the type and size of facility. ■ Overall costs should be low in comparison to other BMPs. Maintenance Sweep paved areas regularly to collect loose particles. Wipe up spills with rags and other absorbent material immediately, do not hose down the area to a storm drain. 4 of 5 California Stormwater BMP Handbook Industrial and Commercial www.cabmphandbooks.com January 2003 Building & Grounds Maintenance SC-41 Supplemental Information Further Detail of the BMP Fire Sprinkler Line Flushing Building fire sprinkler line flushing may be a source of non-stormwater runoff pollution. The water entering the system is usually potable water, though in some areas it may be non-potable reclaimed wastewater. There are subsequent factors that may drastically reduce the quality of the water in such systems. Black iron pipe is usually used since it is cheaper than potable piping, but it is subject to rusting and results in lower quality water. Initially, the black iron pipe has an oil coating to protect it from rusting between manufacture and installation; this will contaminate the water from the first flush but not from subsequent flushes. Nitrates, poly- phosphates and other corrosion inhibitors, as well as fire suppressants and antifreeze may be added to the sprinkler water system. Water generally remains in the sprinkler system a long time (typically a year) and between flushes may accumulate iron, manganese, lead, copper, nickel, and zinc. The water generally becomes anoxic and contains living and dead bacteria and breakdown products from chlorination. This may result in a significant BOD problem and the water often smells. Consequently dispose fire sprinkler line flush water into the sanitary sewer. Do not allow discharge to storm drain or infiltration due to potential high levels of pollutants in fire sprinkler line water.

The protocols in this fact sheet are intended to prevent or reduce the discharge of pollutants from parking/storage areas and include using good housekeeping practices, following appropriate cleaning BMPs, and training employees. Approach The goal of this program is to ensure storm water pollution prevention practices are considered when conducting activities on or around parking areas and storage areas to reduce potential for pollutant discharge to receiving waters. Successful implementation depends on effective training of employees on applicable BMPs and general pollution prevention strategies and objectives. Pollution .Prevention ■ Encourage alternative designs and maintenance strategies for impervious parking lots. (See New Development and Redevelopment BMP Handbook) ■ Keep accurate maintenance logs to evaluate BMP implementation.

Remove debris in a timely fashion. ■ Allow sheet runoff to flow into biofilters (vegetated strip and swale) and/or infiltration devices. ■ Utilize sand filters or oleophilic collectors for oily waste in low quantities. ■ Arrange rooftop drains to prevent drainage directly onto paved surfaces. ■ Design lot to include semi-permeable hardscape. ■ Discharge soapy water remaining in mop or wash buckets to the sanitary sewer through a sink, toilet, clean-out, or wash area with drain. Controlling Litter ■ Post "No Littering" signs and enforce anti-litter laws. ■ Provide an adequate number of litter receptacles. ■ Clean out and cover litter receptacles frequently to prevent spillage. ■ Provide trash receptacles in parking lots to discourage litter. ■ Routinely sweep, shovel, and dispose of litter in the trash. Surface Cleaning ■ Use dry cleaning methods (e.g., sweeping, vacuuming) to prevent the discharge of pollutants into the stormwater conveyance system if possible. ■ Establish frequency of public parking lot sweeping based on usage and field observations of waste accumulation. ■ Sweep all parking lots at least once before the onset of the wet season. ■ Follow the procedures below if water is used to clean surfaces: Block the storm drain or contain runoff. Collect and pump wash water to the sanitary sewer or discharge to a pervious surface. Do not allow wash water to enter storm drains. Dispose of parking lot sweeping deb1is and dirt at a landfill. ■ Follow the procedures below when cleaning heavy oily deposits: 2 of 4 Clean oily spots with absorbent mate1ials. Use a screen or filter fabric over inlet, then wash surfaces. California Stormwater BMP Handbook Industrial and Commercial www.cabmphandbooks.com January 2003 Parking/Storage Area Maintenance SC-43 Do not allow discharges to the storm drain. Vacuum/pump discharges to a tank or discharge to sanitary sewer. Appropriately dispose of spilled materials and absorbents. Surface Repair ■ Preheat, transfer or load hot bituminous material away from storm drain inlets. ■ Apply concrete, asphalt, and seal coat during dry weather to prevent contamination from contacting stormwater runoff. ■ Cover and seal nearby storm drain inlets where applicable (with waterproof mate1ial or mesh) and manholes before applying seal coat, slurry seal, etc. Leave covers in place until job is complete and all water from emulsified oil sealants has drained or evaporated. Clean any debris from these covered manholes and drains for proper disposal. ■ Use only as much water as necessary for dust control, to avoid runoff. ■ Catch drips from paving equipment that is not in use with pans or absorbent mate1ial placed under the machines. Dispose of collected material and absorbents properly. Inspection ■ Have designated personnel conduct inspections of parking facilities and stormwater conveyance systems associated with parking facilities on a regular basis. ■ Inspect cleaning equipment/sweepers for leaks on a regular basis. Training ■ Provide regular training to field employees and/or contractors regarding cleaning of paved areas and proper operation of equipment. ■ Train employees and contractors in proper techniques for spill containment and cleanup. Spill Response and Prevention ■ Keep your Spill Prevention Control and Countermeasure (SPCC) Plan up-to-date. ■ Place a stockpile of spill cleanup materials where it will be readily accessible or at a central location. ■ Clean up fluid spills immediately with absorbent rags or material. ■ Dispose of spilled material and absorbents properly. Other Considerations Limitations related to sweeping activities at large parking facilities may include high equipment costs, the need for sweeper operator training, and the inability of current sweeper technology to remove oil and grease. January 2003 California Stormwater BMP Handbook Industrial and Commercial www .cabmphandbooks.com 3 of 4 SC-43 Parking/Storage Area Maintenance Requirements Costs Cleaning/sweeping costs can be quite large. Construction and maintenance of stormwater structural controls can be quite expensive as well. Maintenance ■ Sweep parking lot regularly to minimize cleaning with water. ■ Clean out oil/water/sand separators regularly, especially after heavy storms. ■ Clean parking facilities regularly to prevent accumulated wastes and pollutants from being discharged into conveyance systems during rainy conditions.

Selection of PDP structural BMPs for storm water pollutant control must be based on the selection process described in Chapter 5. PDPs subject to hydromodification management requirements must also implement structural BMPs for flow control for hydromodification management (see Chapter 6 of the BMP Design Manual). Both storm water pollutant control and flow control for hydromodification management can be achieved within the same structural BMP(s). PDP structural BMPs must be verified by the City at the completion of construction. This may include requiring the project owner or project owner's representative to certify construction of the structural BMPs (see Section 1.12 of the BMP Design Manual). PDP structural BMPs must be maintained into perpetuity, and the City must confirm the maintenance (see Section 7 of the BMP Design Manual). Use this form to provide narrative description of the general strategy for structural BMP implementation at the project site in the box below. Then complete the PDP structural BMP summary information sheet for each structural BMP within the project (copy the BMP summary information page as many times as needed to provide summary information for each individual structural BMP). Describe the general strategy for structural BMP implementation at the site. This information must describe how the steps for selecting and designing storm water pollutant control BMPs presented in Section 5.1 of the BMP Design Manual were followed, and the results (type of BMPs selected). For projects requiring hydromodification flow control BMPs, indicate whether pollutant control and flow control BMPs are integrated together or separate. The majority of the work on this project is concrete and asphalt rehabilitation. There is minimal full-depth removal that unearths subgrade onsite. Because of this, the actual area of new and/or replaced impervious area is 37,043 sf. The site soils are not conducive to infiltration (0.01 -0.06 in/hr measured per Geotechnical Evaluation of The Beacon Project by Ninyo & Moore dated 9/1 /17, proj. 108375001 ). Reuse was also determined to be infeasible. As such bio-treatment BMPs were utilized to meet water quality goals for the site. Said BMPs also provide for attenuation of peak flows to manage hydromodification goals. To treat runoff equivalent to the area of new and replaced impervious areas, there is one biofiltration planter at the north driveway and 4 other biofiltration planters in the parking lot. Infiltration is not feasible due to the low infiltration rates. See geotechnical report in Attachment 6. The runoff will be captured by proposed inlets on-site and conveyed via storm drain pipe to the biofiltration planter.

The site is located across the street from Encinitas Creek, which drains to Batiquitos Lagoon, located in the northwest quadrant of said intersection, The site lies within the HU 904.4 Encinitas Hydrologic Unit, 12-180703030503 and is subject to hydromodification requirements as required by the City's BMP Manual for priority projects draining to non-improved channels. Section I. HYDROMODIFICATION Overall, the site will meet existing hydrologic flow rates per the City's BMP Manual. 1.1. METHODOLOGY Per the BMP Manual For flow rates ranging from 1 O percent, 30 percent or 50 percent of the pre-development 2- year runoff event (0.1O2, 0.3Q2, or 0.5O2) to the pre-development 10-year runoff event (Q10), the post-project discharge rates and durations shall not deviate above the pre-development rates and durations by more than 10 percent over and more than 10 percent over. Per Appendix G. 1. 6: Guidance for Continuous Simulation and Hydromodification Management Sizing Factors, of the City's BMP Manual: 1. For flow rates ranging from 10 percent, 30 percent or 50 percent of the pre- development 2-year runoff event (0. 1 Q2, 0. 3Q2, or 0. 5Q2) to the pre-development 10- year runoff event (Q10), the post-project discharge rates and durations shall not deviate above the pre-development rates and durations by more than 10 percent over and more than 10 percent of the length of the flow duration curve. The specific lower flow threshold will depend on the erosion susceptibility of the receiving stream for the project site [0.1Q2 assumed, worst case per Manual] 2. For flow rates ranging from the lower flow threshold to Q5, the post-project peak flows shall not exceed pre-development peak flows. For flow rates from Q5 to Q10, post-project peak flows may exceed pre-development flows by up to 10 percent. 3. To demonstrate that a flow control facility meets hydromodification management performance standards, peak flow frequency curves and flow duration summary must be generated and compared for pre-development and post-project conditions. 1.2. EXISTING CONDITIONS Per the BMP Manual, the "pre-development" condition will be utilized as a baseline with all Area modeled as pervious for hydromodification simulations. "Existing" conditions were not utilized. 1.3. PROPOSED CONDITIONS As the project consists of several areas of new and replaced impervious areas, and said areas of work drain predominantly to existing impervious areas and existing drainage structures, new structural BMPs installed to comply with hydromodification could not feasibly installed without significantly increasing the scope of the project. Thus the BMPs were sized based on disturbed areas, and sited to capture existing impervious areas equal to or greater than the impervious areas created or replaced. Therefore, the tributary area was modeled as 100% imperviousness, consistent with the design intent and the applicable drainage area. See Attachment 1 E for Sizing Exhibits Table 1: DMA Statistics OMA 1 2 3 4 Area (ac) 0.38 0.18 0.12 0.32 Area (sf) 16,403 7,676 5,246 14,075 % impervious 96% 96% 94% 95% The BMPs were sized per City sizing criteria and modeled using San Diego Hydrology Model (SOHM), an approved Model, with rainfall from the Oceanside rain gage. As shown in the SOHM results, the flow is reduced in the mitigated analysis. Figure 1: Flow/Frequency Analysis Flow Frequency Return Periods for Predeveloped.

E!! d in g As the BMPs are designed, by code, to treat the 85% storm, the 100% storm (Q1) can be attenuated by definition and via the flow rate of the bio-filter material. Additionally, as shown by modeling, the worksheet-sized BMPs also attenuate the 0.1 Q2 event, and events in between. A significant portion of the design, to bring the lower threshold events into compliance, was the design of the underdrains and orifice controls. Through trial and error, with special regard to the 0.1 Q2 event, the ultimate size of the office that would allow for compliance with the hydromodification aspect of the requirements, resulted in an orifice diameter of 7/16". As shown in images below, the draw down for each BMP was also analyzed in SOHM. While the layout, and input factors can be found within the SOHM output report, the drawdown can only be considered on a case-by-case basis. As shown, the drain time is less than 96 hours.

Hydromodification element Per the SUSMP and Hydromodification Management Plan, since the project does not propose an increase greater than 10% to pre-development peak flow rates and/or peak flow durations, the site complies with hydromodification requirements.
