Quality Management Plans (WQMP) conforming to the current National Pollutant Discharge <br /> Elimination System (NPDES) requirements, prepared by a Licensed Civil Engineer or <br /> Environmental Engineer, shall be submitted to the Public Works Agency for review and <br /> approval. <br /> a. A SWPPP shall be prepared and updated as needed during the course of construction to <br /> satisfy the requirements of each phase of the development. The plan shall incorporate all <br /> necessary Best Management Practices (BMPs) and other City requirements to eliminate <br /> polluted runoff until all construction work for the project is completed. The SWPPP shall <br /> include treatment and disposal of all dewatering operation flows, and for nuisance flows during <br /> construction. The SWPPP may include, but would not necessarily be limited to, the following <br /> applicable measures: <br /> o Minimum required pavement widths for residential streets needed to comply with all <br /> zoning and applicable ordinances <br /> o Use permeable materials for private sidewalks, driveways, parking lots, or interior <br /> roadway surfaces <br /> o Reduce the overall imperviousness associated with parking lots by using pervious <br /> materials in spillover parking areas <br /> o Direct rooftop runoff to pervious areas and avoid routing rooftop runoff to the roadway <br /> or the stormwater conveyance system <br /> o Biofilters including vegetated swales and strips <br /> o Extended/dry detention basins <br /> o Infiltration basin <br /> o Infiltration trenches or vaults <br /> o Catch basin inserts <br /> o Continuous flow deflection/separation systems <br /> o Storm drain inserts <br /> o Media filtration <br /> o Foundation planting <br /> o Catch basin screens <br /> o Normal flow storage/separation systems <br /> o Clarifiers <br /> o Filtration systems <br /> o Primary waste water treatment systems <br /> o Dry Wells <br /> o Cistern <br /> b. A WQMP shall be prepared, maintained, and updated as needed to satisfy the requirements <br /> of the adopted NPDES program. The plan shall incorporate water quality measures for all <br /> improved phases of the project.

If existing facilities <br /> are not adequate to handle runoff that may be generated by the proposed development, then <br /> the applicant shall propose feasible remedies to assure that adequate drainage facilities will be <br /> available prior to issuance of occupancy permits. The applicant may propose storm drain <br /> improvements to be constructed in order to meet project needs.
