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 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 local jurisdiction 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 manual). PDP structural BMPs must be maintained into perpetuity, and the local jurisdiction must confirm the maintenance (see Section 7 of the 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 (page 3 of this form) 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). 17 December 2017 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 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 or separate. The selection, sizing, and preliminary design of stormwater treatment and other control measures in this plan was done based on City of Poway’s Storm Water Design Manual meet the requirements of the San Diego Regional Water Quality Control Board Order R9-2013- 0001. Six biofiltration basins were designed to meet the Water Quality and Hydromodification Requirements. The basins were designed to capture 1.5 times the design capture volume (DCV). Tree wells have been designed to provide water quality treatment for agricultural DMAs (AG DMAs 1-10). The tree wells will treat all pollutants of concern generated by these agricultural areas. Treewell design details and locations will be provided during final engineering. 18 December 2017 Form I-6 Page 2 of 6 (Page reserved for continuation of description of general strategy for structural BMP implementation at the site) 19 December 2017 Form I-6 Page 3 of 6 Structural BMP Summary Information (Copy this page as needed to provide information for each individual proposed structural BMP) Structural BMP ID No. Combo BF-1 Construction Plan Sheet No. TBD Type of structural BMP: Retention by harvest and use (HU-1) Retention by infiltration basin (INF-1) Retention by bioretention (INF-2) Retention by permeable pavement (INF-3) Partial retention by biofiltration with partial retention (PR-1) ☒Biofiltration (BF-1) Flow-thru treatment control with prior lawful approval to meet earlier PDP requirements (provide BMP type/description in discussion section below) Flow-thru treatment control included as pre-treatment/forebay for an onsite retention or biofiltration BMP (provide BMP type/description and indicate which onsite retention or biofiltration BMP it serves in discussion section below) Flow-thru treatment control with alternative compliance (provide BMP type/description in discussion section below) Detention pond or vault for hydromodification management Other (describe in discussion section below) Purpose: Pollutant control only Hydromodification control only ☒Combined pollutant control and hydromodification control Pre-treatment/forebay for another structural BMP Other (describe in discussion section below) Who will certify construction of this BMP?

While the calculations performed herein are deemed to be in compliance with Permit requirements, applicants may elect to provide their own calculations. Use of this tool is optional and the County will not be held liable for any errors or other negative impacts associated with its use. In the event that the County performs updates to these worksheets, applicants that have not established reliance on previous versions of the worksheet via discretionary approval may be required to utilize the latest version of the worksheets. A summary of version releases is included below. PDS Land Development Project Manager -Questions relating to specific projects, submittal requirements, approval process, and/or policy-related issues should be directed your PDS Land Development Project Manager (link below). -General questions/comments on this worksheet may be directed to Charles Mohrlock in the County of San Diego Watershed Protection Program (link below). General:To use this workbook, navigate to each of the worksheet tabs below and populate all yellow cells with project specific information. Yellow cells require user input, white cells are locked for editing and are automatically calculated, blue cells are also locked for editing and are automatically populated based on results from previous worksheet tabs, grey cells are items that do not require user input because of previous user inputs, orange cells represent warnings where supplemental information and/or revisions may be required for compliance. The worksheets are formatted to accommodate calculations for up to 10 drainage areas and associated BMPs. Each drainage area and BMP is represented as a discrete column with corresponding user inputs and calculations appearing in the rows below. Please note that projects with more than 10 drainage areas may need to use more than one workbook to accommodate the entire project. Step 1. DCV:Provide the required inputs to determine the design capture volume for each PDP drainage area. The calculations in this worksheet determine the initial design capture volume and also apply any applicable reductions associated with site design techniques including dispersion to pervious surfaces, incorporation of tree wells, and incorporation of rain barrels. Step 2. Retention Requirements:Provide required inputs to determine the minimum retention requirements for each drainage area. Step 3. BMP Performance: Provide required inputs to determine the portion of the pollutant control performance standards that are satisfied by the proposed BMPs. Reduced Size BMP Maintenance (optional):If BMPs with a footprint of less than 3% of the effective impervious tributary are proposed, provide required inputs to determine the anticipated frequency for major BMP maintenance activities. Welcome to the County of San Diego Automated Stormwater Pollutant Control Worksheets. These worksheets may be used to demonstrate compliance with stormwater pollutant control standards set forth in the 2013 MS4 Permit for Priority Development Projects and Green Street Projects. charles.mohrlock@sdcounty.ca.gov Category #Description i ii iii iv v vi vii viii ix x Units 1 Drainage Basin ID or Name AG DMA 1 AG DMA 2 AG DMA 3 AG DMA 4 AG DMA 5 AG DMA 6 AG DMA 7 AG DMA 8 AG DMA 9 AG DMA 10 unitless 2 85th Percentile 24-hr Storm Depth 0.68 0.68 0.68 0.68 0.68 0.68 0.68 0.68 0.68 0.68 inches 3 Impervious Surfaces Not Directed to Dispersion Area (C=0.90) 37,508 24,546 22,334 68,755 116,239 46,853 65,842 85,671 26,934 160,058 sq-ft 4 Semi-Pervious Surfaces Not Serving as Dispersion Area (C=0.30)sq-ft 5 Engineered Pervious Surfaces Not Serving as Dispersion Area (C=0.10)sq-ft 6 Natural Type A Soil Not Serving as Dispersion Area (C=0.10)sq-ft 7 Natural Type B Soil Not Serving as Dispersion Area (C=0.14)sq-ft 8 Natural Type C Soil Not Serving as Dispersion Area (C=0.23) 337,569 36,819 33,501 103,133 174,358 70,279 98,763 128,507 40,401 240,087 sq-ft 9 Natural Type D Soil Not Serving as Dispersion Area (C=0.30)sq-ft 10 Does Tributary Incorporate Dispersion, Tree Wells, and/or Rain Barrels?Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes yes/no 11 Impervious SurfacesDirected to Dispersion Area per SD-B (Ci=0.90)sq-ft 12 Semi-Pervious Surfaces Serving as Dispersion Area per SD-B (Ci=0.30)sq-ft 13 Engineered Pervious Surfaces Serving as Dispersion Area per SD-B (Ci=0.10)sq-ft 14 Natural Type A Soil Serving as Dispersion Area per SD-B (Ci=0.10)sq-ft 15 Natural Type B Soil Serving as Dispersion Area per SD-B (Ci=0.14)sq-ft 16 Natural Type C Soil Serving as Dispersion Area per SD-B (Ci=0.23)sq-ft 17 Natural Type D Soil Serving as Dispersion Area per SD-B (Ci=0.30)sq-ft 18 Number of Tree Wells Proposed per SD-A 16 5 4 12 20 8 12 15 5 27 # 19 Average Mature Tree Canopy Diameter 30 30 30 30 30 30 30 30 30 30 ft 20 Number of Rain Barrels Proposed per SD-E # 21 Average Rain Barrel Size gal 22 Total Tributary Area 375,077 61,365 55,835 171,889 290,597 117,132 164,605 214,178 67,334 400,146 sq-ft 23 Initial Runoff Factor for Standard Drainage Areas 0.30 0.50 0.50 0.50 0.50 0.50 0.50 0.50 0.50 0.50 unitless 24 Initial Runoff Factor for Dispersed & Dispersion Areas 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 unitless 25 Initial Weighted Runoff Factor 0.30 0.50 0.50 0.50 0.50 0.50 0.50 0.50 0.50 0.50 unitless 26 Initial Design Capture Volume 6,376 1,739 1,582 4,870 8,234 3,319 4,664 6,068 1,908 11,337 cubic-feet 27 Total Impervious Area Dispersed to Pervious Surface 0 0 0 0 0 0 0 0 0 0 sq-ft 28 Total Pervious Dispersion Area 0 0 0 0 0 0 0 0 0 0 sq-ft 29 Ratio of Dispersed Impervious Area to Pervious Dispersion Area n/a n/a n/a n/a n/a n/a n/a n/a n/a n/a ratio 30 Adjustment Factor for Dispersed & Dispersion Areas 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 1.00 ratio 31 Runoff Factor After Dispersion Techniques 0.30 0.50 0.50 0.50 0.50 0.50 0.50 0.50 0.50 0.50 unitless 32 Design Capture Volume After Dispersion Techniques 6,376 1,739 1,582 4,870 8,234 3,319 4,664 6,068 1,908 11,337 cubic-feet 33 Total Tree Well Volume Reduction 6,720 2,100 1,680 5,040 8,400 3,360 5,040 6,300 2,100 11,340 cubic-feet 34 Total Rain Barrel Volume Reduction 0 0 0 0 0 0 0 0 0 0 cubic-feet 35 Final Adjusted Runoff Factor 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 unitless 36 Final Effective Tributary Area 0 0 0 0 0 0 0 0 0 0 sq-ft 37 Initial Design Capture Volume Retained by Site Design Elements 6,720 2,100 1,680 5,040 8,400 3,360 5,040 6,300 2,100 11,340 cubic-feet 38 Final Design Capture Volume Tributary to BMP 0 0 0 0 0 0 0 0 0 0 cubic-feet False False Automated Worksheet B.1: Calculation of Design Capture Volume (V2.0) Dispersion Area, Tree Well & Rain Barrel Inputs (Optional) Standard Drainage Basin Inputs Results Tree & Barrel Adjustments Initial Runoff Factor Calculation Dispersion Area Adjustments No Warning Messages Appendix I: Forms and Checklists I-27 February 2016     Categorization of Infiltration Feasibility Condition Form I-8 Part 1 - Full Infiltration Feasibility Screening Criteria Would infiltration of the full design volume be feasible from a physical perspective without any undesirable consequences that cannot be reasonably mitigated? Criteria Screening Question Yes No 1 Is the estimated reliable infiltration rate below proposed facility locations greater than 0.5 inches per hour? The response to this Screening Question shall be based on a comprehensive evaluation of the factors presented in Appendix C.2 and Appendix D.                 X  Based on information collected from the USDA NRCS website, The entire property is underlain with soils classified as Hydrologic Soil Group C and D, which are not considered suitable for full infiltration BMP’s. All of basins will be graded and result in compacted fill ranging between 15 to 18 feet thick, or will expose competent granitic rock possibly requiring blasting to excavate. Infiltration BMP’s supported by compacted fill are not recommended due to the increased potential for soil saturation, settlement of granular fill soils, heaving of expansive soils, and lateral water migration. Lateral water migration could result in distress to downgradient public and private properties and improvements. In addition, compacted fill will not exhibit design infiltration rates of 0.5 inches per hour or greater. The underlying granitic rock is considered practically impermeable and will not exhibit design infiltration rates of 0.5 iph or greater. 2 Can infiltration greater than 0.5 inches per hour be allowed without increasing risk of geotechnical hazards (slope stability, groundwater mounding, utilities, or other factors) that cannot be mitigated to an acceptable level? The response to this Screening Question shall be based on a comprehensive evaluation of the factors presented in Appendix C.2.                   X  Provide basis: Infiltration BMP’s supported by compacted fill are not recommended. The potential for long-term settlement of the granular fill soils, heaving of the near surface expansive soils, and lateral water migration to adversely impact existing and proposed utilities and to adversely impact existing and proposed foundations and improvements is high. The underlying granitic rock is considered practically impermeable, therefore basins supported on the granitic rock will result in daylight water seepage, lateral water migration, ponding of water for extended time periods, and slope instability if the water migrates laterally into compacted fill and slope areas. Appendix I: Forms and Checklists I-28 February 2016     Form I-8 Page 2 of 4 Criteria Screening Question Yes No 3 Can infiltration greater than 0.5 inches per hour be allowed without increasing risk of groundwater contamination (shallow water table, storm water pollutants or other factors) that cannot be mitigated to an acceptable level? The response to this Screening Question shall be based on a comprehensive evaluation of the factors presented in Appendix C.3.                X    Groundwater is not located within 10 feet from the bottom of any proposed basins, therefore the risk of storm water infiltration BMP’s adversely impacting groundwater is considered negligible. 4 Can infiltration greater than 0.5 inches per hour be allowed without causing potential water balance issues such as change of seasonality of ephemeral streams or increased discharge of contaminated groundwater to surface waters? The response to this Screening Question shall be based on a comprehensive evaluation of the factors presented in Appendix C.3.                X    It is our opinion there are no adverse impacts to groundwater, water balance impacts to stream flow, or impacts on any downstream water rights. It should be noted that researching downstream water rights or evaluating water balance issues to stream flows is beyond the scope of the geotechnical consultant. Part 1 Result * If all answers to rows 1 - 4 are “Yes” a full infiltration design is potentially feasible. The feasibility screening category is Full Infiltration If any answer from row 1-4 is “No”, infiltration may be possible to some extent but would not generally be feasible or desirable to achieve a “full infiltration” design.

Criteria Screening Question Yes No 5 Do soil and geologic conditions allow for infiltration in any appreciable rate or volume? The response to this Screening Question shall be based on a comprehensive evaluation of the factors presented in Appendix C.2 and Appendix D.                    X    Unless infiltration testing is performed and results in design infiltration rates of 0.05 iph or less, which is considered the recognized low bound design rate for partial infiltration, partial infiltration BMP’s incorporating side liners and subdrains could be used to reasonably mitigate the adverse impacts of infiltration. 6 Can Infiltration in any appreciable quantity be allowed without increasing risk of geotechnical hazards (slope stability, groundwater mounding, utilities, or other factors) that cannot be mitigated to an acceptable level? The response to this Screening Question shall be based on a comprehensive evaluation of the factors presented in Appendix C.2.                 X    Unless infiltration testing is performed and results in design infiltration rates of 0.05 iph or less, which is considered the recognized low bound design rate for partial infiltration, partial infiltration BMP’s incorporating side liners and subdrains could be used to reasonably mitigate the adverse impacts of infiltration. Appendix I: Forms and Checklists I-30 February 2016     Form I-8 Page 4 of 4 Criteria Screening Question Yes No 7 Can Infiltration in any appreciable quantity be allowed without posing significant risk for groundwater related concerns (shallow water table, storm water pollutants or other factors)? The response to this Screening Question shall be based on a comprehensive evaluation of the factors presented in Appendix C.3.                 X    Groundwater is not located within 10 feet from the bottom of any proposed basins, therefore the risk of storm water infiltration BMP’s adversely impacting groundwater is considered negligible. 8 Can infiltration be allowed without violating downstream water rights? The response to this Screening Question shall be based on a comprehensive evaluation of the factors presented in Appendix C.3.                X    It is our opinion there are no adverse impacts to groundwater, water balance impacts to stream flow, or impacts on any downstream water rights. It should be noted that researching downstream water rights or evaluating water balance issues to stream flows is beyond the scope of the geotechnical consultant. Part 2 Result* If all answers from row 5-8 are yes then partial infiltration design is potentially feasible. The feasibility screening category is Partial Infiltration. If any answer from row 5-8 is no, then infiltration of any volume is considered to be infeasible within the drainage area. The feasibility screening category is No Infiltration.           Partial          Infiltration  *To be completed using gathered site information and best professional judgment considering the definition of MEP in the MS4 Permit.

SWMM models will be provided in the next submittal for the pre and post developed conditions at the site in order to determine if the proposed biofiltration facilities have sufficient storage volume to meet the current Hydromodification Management Plan (HMP) requirements from the Regional Water Quality Control Board (RWQCB). SWMM Model Development The Farm development plan proposes the construction of single family homes, agricultural areas, and social amenities. Three Points of Compliance (POC) will be analyzed in the SWMM analysis. The applicable POCs for The Farm project are numbered POC 1, 2, 3. An assumed impervious was used for each pad based on its proposed land use and Table 3-1 from the San Diego County Hydrology Manual to provide preliminary sizing for basins necessary for ultimate land use for hydromodification management. Basin design is also modeled as a basin with vertical sides in order to simplify calculations. Development for each pad must provide the same basin bottom with 3:1 slope required in the City BMP DM. Two SWMM models will be prepared for each of the three POCs, one for the pre, and one for the post development. The inputs required to run a SWMM analysis are rainfall, evaporation rate, area, drainage soil, and any BMP configuration applicable to the project based on the 2016 BMP DM. The rain gauge used is the Poway Gage as it is the most representative of the area based on location. Evaporation for the project site will be taken from BMP DM for Zone 4 for the monthly average evapotranspiration. Hydrologic soil type C will be assumed for the entire site based on the web soil survey. Page 2 R:\1390\&Hyd\REPORTS\HMP\1390-HMP.docx HMP Modeling POC 1 POC 1 is located offsite to the south of Espola Road and discharges via a triple arch culvert. It receives runoff from DMA 1 and DMA 2 ·DMA 1 consists of the roads, single family homes, gardens, and social amenities located on the northern side of Espola Blvd. The flow that is generated by DMA 1 is intercepted by inlets and routed to the combo basin titled Combo BF-1. After W.Q. treatment is provided by the biofiltration basin, Flow is routed to POC-1 via a storm drain network. · DMA 2 consists of the roads, single family homes, and gardens located just west of Tom O’Shanter Dr. The flow that is generated by DMA 2 is intercepted by inlets and routed to the biofiltration basin titled BF-2. After W.Q. treatment is provided by the biofiltration basin, Flow is routed to POC-1 via a storm drain network. ·The offsite residential areas consist of the neighborhoods along Tom O’shanter Drive and Cloudcroft Court (Offsite Residential Areas 1 and 2 on the HMP map) that are conveyed through the site to the east and west. These areas are routed through the site and no water quality treatment is required. ·The agricultural DMAs tributary to POC 1 include AG DMA 1, AG DMA 2, AG DMA 3, AG DMA 4, AG DMA 5, AG DMA 6, & AG DMA 7. POC 2 The drainage area for POC5 collects drainage from DMA 3, DMA 4, and DMA 6. ·DMA 3 consists of the roads, single family homes, and gardens located just north of DMA 1. The flow that is generated by DMA 3 is intercepted by inlets and routed to the biofiltration basin titled BF-3. After W.Q. treatment is provided by the biofiltration basin, Flow is routed to POC-2 via a storm drain network. ·DMA 4 consists of the roads, single family homes, and gardens located just east of DMA 3. The flow that is generated by DMA 4 is intercepted by inlets and routed to the biofiltration basin titled BF-4. After W.Q. treatment is provided by the biofiltration basin, Flow is routed to POC-2 via a brow ditch and storm drain network. ·DMA 6 consists of the roads, single family homes, and gardens located north of DMA 4. The flow that is generated by DMA 6 is intercepted by inlets and routed to the biofiltration basin titled BF-4. After W.Q. treatment is provided by the biofiltration basin, Flow is routed to POC-2 via an open brow ditch and storm drain network. ·The agricultural DMAs tributary to POC 1 include AG DMA 7, AG DMA 8, AG DMA 9, AG DMA 10. Page 3 R:\1390\&Hyd\REPORTS\HMP\1390-HMP.docx POC 3 receives flow from DMA 5. ·DMA 5 consists of the roads, single family homes, and gardens located east of DMA 4. The flow that is generated by DMA 5 is intercepted by inlets and routed to the biofiltration basin titled BF-4. After W.Q. treatment is provided by the biofiltration basin, Flow is routed to POC-2 via a natural channel and storm drain network. Biofiltration Modeling Developed storm water runoff is routed through six (6) biofiltration basins. The basins were modeled using the bioretention LID module within SWMM. The bioretention module can model the underground gravel storage layer, underdrain with an orifice plate, amended soil layer, and a surface storage pond up to the elevation of the invert of the bottom orifice. A separate diversion and detention basin were used to model the portion of the storage pond between the base orifice invert elevations and the spillway elevation from the biofiltration basin. Once runoff has been routed through the respective basin outlet structures, it is conveyed via a storm drain pipe to each POC. Basin Discussion: Flow control in the basin is achieved using multiple orifices on a concrete riser box. The size, number and location of the orifices are presented in the Table 1. Each basin also contains an emergency overflow riser that is only utilized in storm events equal to or larger than the 100- year storm. Sizing and further peak flow discussion is in the “Drainage Report for The Farms” Page 4 R:\1390\&Hyd\REPORTS\HMP\1390-HMP.docx Typical Biofiltration Details Page 5 R:\1390\&Hyd\REPORTS\HMP\1390-HMP.docx Basin Discussion Flow control in the basin is achieved using multiple orifices on a concrete riser box. The size, number and location of the orifices are presented in the Basin Table below. Each basin also contains an emergency overflow riser that is only utilized in storm events equal to or larger than the 100 year storm. Sizing and further peak flow discussion is included in the “Drainage Report for The Farm”.

The FDC was compared between 10% of the existing condition Q2 (based on accepting an assumption of high susceptibility for downstream channel erosion as required if no soils tests are completed) up to the existing condition Q10. The Q2 and Q10 were determined using a partial duration statistical analysis of the runoff time series in an Excel spreadsheet. The SWMM Model is a statistical analysis based on the Weibull Plotting Position Method. The range between 10% of Q2 and Q10 was divided into 100 equal time intervals; the number of hours that each flow rate was exceeded was counted from the hourly series. Additionally, the intermediate peaks with a return period “i” were obtained (Qi with i=3 to 9). For the purpose of the plot, the values were presented as percentage of time exceeded for each flow rate. The FDC comparison for POCs 1 -3 are illustrated in Figure 1, 2 & 3. POC 1 corresponds with the point located downstream of the discharge of Basins 1 & 2. POC 2 corresponds with the point located downstream of the discharge of Basins 3, 4 & 6. POC 3 corresponds with the point downstream of the offsite discharge of Basin 5. As can be seen in Figures 1 & 2, the FDC for the proposed condition with six (6) separate basins is within 110% of the curve for the existing condition. The additional runoff volume generated from developing the site will be released to the downstream storm drain at a flow rate below the 10% Q2 lower threshold. Additionally, the project will not increase peak flow rates between the Q2 and the Q10, as shown in the graphic and also in the attached table. Page 10 R:\1390\&Hyd\REPORTS\HMP\1390-HMP.docx Elevation vs Area For the portion of the flow diverted in the LID Control to the receiving detention basin, a pond is used to route the hydrographs, The elevation vs area curve in the model is calculated in excel and imported into the model at a 0.10 interval range Elevation vs Discharge The total discharge peak flow is imported from an excel spreadsheet that calculated the elevation vs discharge of the multiple outlet system The orifice configurations have been selected to maximize their size while restricting flow to conform to the required 10% of the Q2 event flow. While we acknowledge that these orifices are small, to increase the size of these outlets would impact the basins’ ability to restrict flow beneath the HMP thresholds, thus preventing the BMP from conforming to HMP requirements. Page 9 R:\1390\&Hyd\REPORTS\HMP\1390-HMP.docx Summary & Conclusion A summary/comparison of existing and proposed areas draining to each point of compliance (POC) are shown in the table below. The model includes onsite project areas and offsite drainage areas. Six biofiltration basins are proposed to mitigate increased flow frequencies as a result of development. The tree-wells designed to treat the agricultural DMAs (see Attachment 1) provide no hydromodification storage. AREA SUMMARY Existing (AC)Proposed (AC) POC 1 160 160 POC 2 35.6 35.6 POC 3 5.00 5.00 The study has demonstrated that the proposed biofiltration basins meet current HMP requirements. Key Assumptions 1.C soils are representative of the entire site. 2.The Tree-wells within Agricultural DMAs are not providing HMP storage. 3.K-Sat Values for sub-catchments in exiting condition were reduced by 25% as recommended by BMP Design Manual to account for existing areas that were impervious due to compacted soils.
