Water Quality Management Plan (WQMP) <br />Mainplace Mall Specific Plan <br />IV.2. Site Design and Drainage <br />Describe site design and drainage including <br />• A narrative of site design practices utilized or rationale for not using practices; <br />• A narrative of how site is designed to allow BMPs to be incorporated to the MEP <br />• A table of DMA characteristics and list of LID BMPs proposed in each DMA. <br />• Reference to the WQMP "BMP Exhibit" <br />• Calculation of Design Capture Volume (DCV) for each drainage area. <br />• A listing of GIS coordinates for LID and Treatment Control BMPs. <br />Refer to Section 2.4.2 in the Technical Guidance Document (TGD). <br />DMA <br />Area <br />DCV <br />Q <br />LID Methodology <br />Number <br />(AC) <br />(CF) <br />(CFS) <br />Parcel 1 <br />5.44 <br />6,500 <br />0.58 <br />Underground infiltration with hydrodynamic separator <br />pretreatment. <br />Parcel 2 <br />1.63 <br />2,000 <br />0.17 <br />Underground infiltration with hydrodynamic separator <br />pretreatment. <br />Parcel 3 <br />1.91 <br />2,300 <br />0.20 <br />Underground infiltration with hydrodynamic separator <br />pretreatment. <br />Parcel 4 <br />1.76 <br />2,100 <br />0.19 <br />Underground infiltration with hydrodynamic separator <br />pretreatment. <br />Parcel 5 <br />2.83 <br />3,400 <br />0.30 <br />Underground infiltration with hydrodynamic separator <br />pretreatment. <br />Parcel 6 <br />22.9 <br />27,500 <br />2.46 <br />Underground infiltration with hydrodynamic separator <br />pretreatment. <br />Parcel 7 <br />4.05 <br />4,900 <br />0.43 <br />Underground infiltration with hydrodynamic separator <br />pretreatment. <br />Parcel 8 <br />3.08 <br />3,700 <br />0.33 <br />Underground infiltration with hydrodynamic separator <br />pretreatment. <br />Parcel 9 <br />1.97 <br />2,400 <br />0.21 <br />Underground infiltration with hydrodynamic separator <br />pretreatment. <br />Parce110 <br />1.66 <br />2,000 <br />0.18 <br />Underground infiltration with hydrodynamic separator <br />pretreatment. <br />NAP <br />2.94 <br />3,500 <br />0.32 <br />Underground infiltration with hydrodynamic separator <br />pretreatment. <br />Since this project is still in a forward planning stage, pecise BMP types and locations <br />ae ubknown at this time. Where feasible, infiltration will be utilized. Where <br />infiltration is infeasible, biofiltration will be utilized. <br />Centennial Section IV <br />Conceptual Specific Plan WQMP Page 21 <br />
