Environmental Analysis <br />HYDROLOGY AND WATER QUALITY <br />• Explain the maintenance program for the projects BMPs; <br />• During construction, require reporting of violations to the Regional Board; <br />• List the parties responsible for SWPPP implementation and BMP maintenance during <br />and after grading. The project proponent shall implement the SWPPP and will modify <br />the SWPPP as directed by the Storm Water Permit. <br />Impact 5.7 -5 <br />-5 Water Quality Management Plan (WQMP). Prior to the issuance of building permits, <br />project specific WQMPs shall be submitted for review and approved by the Building <br />Department. The WQMP shall identify the best management practices (BMPs) that will be <br />used on the site to control predictable pollutant runoff More specifically, the WQMP shall: <br />• Describe the routine and special post construction BMPs to be used at the proposed <br />development site (including both structural and non - structural measures); <br />• Describe responsibility for the initial implementation and long -term maintenance of the <br />BMPs; <br />• Provide narrative with the graphic materials as necessary to specify the locations of the <br />structural BMPs; <br />• Certify that the project applicant will seek to have the WQMP carried out by all future <br />successors or assigns to the property. <br />Impact 5.7 -6 <br />Mitigation Measure 7 -1 applies. <br />7 -6 Prior to the issuance of precise grading permit for any lot or parcel wholly or partially <br />located within the 100 -year floodplain, the applicant shall furnish to the City Engineer <br />documentation required by FEMA for approval of the Conditional Letter of Map <br />Revision /Letter of Map Revision (CLOMR /LOMR) process.
