(See <br /> planting guide line by Alameda County Clean Water Program.) <br /> III. Plant materials selected shall be appropriate to site specific <br /> characteristics such as soil type, topography, climate, amount and <br /> timing of sunlight, prevailing winds, rainfall, air movement, patterns of <br /> land use, ecological consistency and plant interactions to ensure <br /> successful establishment. <br /> IV. Landscaping shall also comply with City of Pleasanton ordinances and <br /> policies regarding water conservation. <br /> e) Roof drains shall discharge and drain away from the building foundation. <br /> Ten percent of the stormwater flow shall drain to landscaped area or to an <br /> unpaved area wherever practicable. <br /> B.

The project developer shall submit a Stormwater Pollution Prevention Plan <br /> (SWPP) for review by the City Engineer/Chief Building Official prior to <br /> issuance of building or engineering permits. A reviewed copy of the SWPPP <br /> shall be available at the project site until engineering and building permits <br /> have been signed off by the inspection departments and all work is complete. <br /> A site specific SWPPP must be combined with proper and timely installation <br /> of the BMPs, thorough and frequent inspections, maintenance, and <br /> documentation. Failure to comply with the reviewed construction SWPPP <br /> may result in the issuance of correction notices, citations or stop work orders. <br /> 24 of 28 <br />
