8.A. - Page 83 <br /> ATTACHMENT3 <br /> a. The post-construction stormwater management plan shall include and <br /> identify the following: <br /> (i) All proposed impervious surface on the site; and <br /> (ii) Anticipated directional flows of on-site stormwater runoff; and <br /> (iii) Site design measures to reduce the amount of impervious surface <br /> area and directly connected impervious surfaces; and <br /> (iv) Source control measures to limit the potential for stormwater <br /> pollution; and <br /> (v) Stormwater treatment measures to remove pollutants from <br /> stormwater runoff; and <br /> (vi) Hydromodification management measures so that post-Project <br /> stormwater runoff does not exceed the flow and duration of pre- <br /> Project runoff, if required under the NPDES permit. <br /> b. The following additional information shall be submitted with the post- <br /> construction stormwater management plan: <br /> (i) Detailed hydraulic sizing calculations for each stormwater treatment <br /> measure proposed; and <br /> (ii) Pollutant removal information demonstrating that any proposed <br /> manufactured/ mechanical (i.e. non-landscape-based) stormwater <br /> treatment measure, when not used in combination with a <br /> landscape-based treatment measure, is capable of removing the <br /> range of pollutants typically removed by landscape-based treatment <br /> measures and/or the range of pollutants expected to be generated <br /> by the Project. <br /> c. All proposed stormwater treatment measures shall incorporate appropriate <br /> planting materials for stormwater treatment (for landscape-based <br /> treatment measures) and shall be designed with considerations for <br /> vector/mosquito control. Proposed planting materials for all proposed <br /> landscape-based stormwater treatment measures shall be included on the <br /> landscape and irrigation plan for the Project. The applicant is not required <br /> to include on-site stormwater treatment measures in the post-construction <br /> stormwater management plan if he or she secures approval from the City <br /> Engineer of an alternative proposal that demonstrates compliance with the <br /> requirements of the Provision C.3 of the National Pollutant Discharge <br /> Elimination System (NPDES) permit issued to the San Mateo Countywide <br /> Clean Water Program. <br /> d. Applicant shall enter into a Stormwater Treatment Measures Maintenance <br /> Agreement, in accordance with Provision C.3.e of the NPDES permit, <br /> which agreement shall provide, among other thing, that: <br /> ATTY/RES0.2785/FINGER RESO APPROVING VTM FINAL <br /> REV:08-31012 VR <br /> Page 15 of 20 <br />
