09/10/2012 (i) Detailed hydraulic sizing calculations for each stormwater treatment measure proposed; and (ii) Pollutant removal information demonstrating that any proposed manufactured/ mechanical (i.e. non-landscape-based) stormwater treatment measure, when not used in combination with a landscape-based treatment measure, is capable of removing the range of pollutants typically removed by landscape-based treatment measures and/or the range of pollutants expected to be generated by the Project. c. All proposed stormwater treatment measures shall incorporate appropriate planting materials for stormwater treatment (for landscape-based treatment measures) and shall be designed with considerations for vector/mosquito control. Proposed planting materials for all proposed landscape-based stormwater treatment measures shall be included on the landscape and irrigation plan for the Project. The applicant is not required to include on-site stormwater treatment measures in the post-construction stormwater management plan if he or she secures approval from the City Engineer of an alternative proposal that demonstrates compliance with the requirements of the Provision C.3 of the National Pollutant Discharge Elimination System (NPDES) permit issued to the San Mateo Countywide Clean Water Program. d. Applicant shall enter into a Stormwater Treatment Measures Maintenance Agreement, in accordance with Provision C.3.e of the NPDES permit, which agreement shall provide, among other thing, that: (i) The applicant accepts responsibility for the adequate installation/ construction, operation, maintenance, inspection, and reporting of any on-site stormwater treatment measures being incorporated into the Project until the responsibility is legally transferred to another entity; and (ii) The applicant provides and ensures legal access to the on-site stormwater treatment measures for representatives of the City, the local vector control district, and staff of the Regional Water Quality Control Board, San Francisco Region, for the purpose of verifying the implementation, operation, and maintenance of the on-site stormwater treatment measures and taking corrective action if necessary. The agreement shall be reviewed and approved by the City prior to recordation and recorded at the County Recorder's Office at the applicant's expense. 38.Applicant shall submit an Erosion and Sediment Control Plan to the City Engineer for review and approval prior to commencing any work on the Project, including demolition or grading work. The Plan shall show Best Management Practices (BMPs) for storm water pollution prevention. ATTY/RES0.2785/FINGER RESO APPROVING VTM FINAL RESO.#15219 REV:08-31012 VR MUFF#613 Page 15 of 19
