The project shall also comply with the "Construction General Permit" by the California <br /> Regional Water Quality Control Board, San Francisco Bay Region. <br /> (http://www.waterboards.ca.gov/water issues/proqrams/stormwater/construction.shtml) <br /> A. Design Requirements <br /> 1. The 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 <br /> or more. <br /> c) The Permit requires a proactive Diazinon pollutant reduction plan (aka <br /> Pesticide Plan) to reduce or substitute pesticide use with less toxic <br /> alternatives. <br /> d) The Permit requires complying with the Copper Pollutant Reduction Plan and <br /> 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 <br /> prepared by a licensed civil engineer depicting all final grades and on-site <br /> drainage control measures including bio-swales. Irrigated bio-swales shall <br /> be redesigned as needed to the satisfaction of the City Engineer to optimize <br /> the amount of the stormwater running off the paved surface that enters the <br /> bio-swale at its most upstream end. This plan shall be subject to the review <br /> and approval of the City Engineer prior to the issuance of any building <br /> permits. <br /> b. In addition to natural controls the project developer may be required to <br /> install a structural control, such as an oil/water separator, sand filter, or <br /> approved equal (in the parking lot) (on the site) to intercept and pre-treat <br /> stormwater prior to reaching the storm drain. The design, locations, and a <br /> schedule for maintaining the separator shall be submitted to the City <br /> Engineer/Chief Building Official for review and approval prior to issuance of <br /> building permits. The structural control shall be cleaned at least twice a <br /> year: once immediately prior to October 15 and once in January. <br /> c. The project developer shall submit sizing design criteria to treat stormwater <br /> runoff and for hydromodification, if required, at the time of PUD plan <br /> submittal and an updated detailed copy of calculations with subsequent <br /> submittals. <br /> Page 15 of 21 <br />
