Department, Public Works/Engineering section at City offices, Alameda County Clean Water <br /> Program and at State Water Board: <br /> (http://www.waterboards.ca.gov/sanfranciscobav/water issues/programs/stormwater/Municipal <br /> /index.shtml; <br /> The project shall comply with the "Construction General Permit" as required by the San <br /> Francisco Bay Regional Water Quality Control Board: <br /> (http://www.waterboards.ca.gov/water issues/programs/stormwater/construction.shtml) <br /> A. Design Requirements <br /> 1. The NPDES Permit design requirements include, but are not limited to, the following: <br /> a. Source control, sight design measures, and design and implementation of <br /> stormwater treatment measures are required when commercial, industrial or <br /> residential development creates and replaces 10,000 square feet or more of <br /> impervious surface, including roof area, streets and sidewalk. <br /> b. Hydro-modification standards are required when a new development or <br /> redevelopment project creates and replaces total impervious area of one acre or <br /> more. <br /> c. The NPDES Permit requires a proactive Diazinon pollutant reduction plan (aka <br /> Pesticide Plan) to reduce or substitute pesticide use with less toxic alternatives. <br /> d. The NPDES Permit requires complying with the Copper Pollutant Reduction Plan <br /> and the Mercury Pollutant Reduction Plan. <br /> 2. The following requirements shall be incorporated into the project: <br /> a. The project developer shall submit a final grading and drainage plan prepared by a <br /> licensed civil engineer depicting all final grades and on-site drainage control <br /> measures including bio-swales. Irrigated bio-swales shall be redesigned as needed <br /> to the satisfaction of the City Engineer to optimize the amount of the stormwater <br /> running off the paved surface that enters the bio-swale at its most upstream end. <br /> This plan shall be subject to the review and approval of the City Engineer prior to the <br /> issuance of any building permits. <br /> b. The project developer shall submit sizing design criteria to treat stormwater runoff <br /> and for hydromodification, if required, at the time of PUD plan submittal and an <br /> updated detailed copy of calculations with subsequent submittals. <br /> c. Landscaping shall be designed to minimize irrigation and runoff, promote surface <br /> infiltration where appropriate and acceptable to the project soils engineer, and <br /> minimize the use of fertilizers and pesticides that can contribute to stormwater <br /> pollution. <br /> PUD-125, 2350 Santa Rita Road Planning Commission <br /> Page 18 of 23 <br />
