<br />. the minimum width of the structure shall be 5 feet, and the slope stabilizing <br />geotextile fabric shall extend a minimum of 5 feet on both sides of the <br />outfall structure. <br /> <br />92. The applicant engineer shall submit storm drain hydraulic calculation to verify that <br />the hydraulic grade line does not exceed city design standards. <br /> <br />93. The building shall pads shall be constructed above the 100-year t100d elevation as <br />established by Alameda County Flood Control Zone 7. The property shall be <br />graded such that no storm water runs directly to the Arroyo. <br /> <br />URBAN STORMW ATER RUNOFF REQUIREMENTS <br /> <br />Stormwater Design Requirements <br /> <br />94. The project shall comply with the Alameda Countywide NPDES Permit <br />#CA5002983I, a copy of which is available at the City offices <br /> <br />95. The following requirements shall be incorporated into the project: <br /> <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 storm water 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 /> <br />b) The project developer shall submit sizing designs criteria to treat <br />stormwater runoff at the time of plan submittal. <br /> <br />c) Landscaping shall be designed to minimize irrigation and runoff, promote <br />surface infiltration where appropriate, and minimize the use of fertilizers <br />and pesticides that can contribute to stormwater pollution. <br /> <br />i) Structures shall be designed to discourage the occurrence and entry <br />of pests into buildings, thus minimizing the need for pesticides. <br /> <br />ii) Where feasible, landscaping shall be designed and operated to treat <br />stormwater runoff. In areas that provide detention of water, plants <br />that are tolerant of saturated soil conditions and prolonged exposure <br />to water shall be specified. Soil shall be amended as required. <br /> <br />14 <br />
