j. Roof drains shall drain away from the building foundation. Stormwater flow shall drain to a landscaped area or to an unpaved area wherever practicable as determined by the City Engineer/Chief Building Official. k. There shall be no direct roof leaders connected to the street gutter/parking lot or storm drain system, unless otherwise approved by the City engineer. B. Construction Requirements The project shall comply with the "Construction General Permit" requirements of the NPDES Permit for construction activities (including other land disturbing activities) that disturb one acre or more (including smaller sites that are part of a larger common plan of development). Information related to the Construction General Permit is on line at: • http://www.waterboards.ca.gov/water issues/programs/stormwater/construction.shtml • http://www.waterboards.ca.gov/water issues/proqrams/stormwater/docs/finalconstper mit.pdf 1. The Construction General Permit's requirements include, but are not limited to, the following: a. The project developer shall obtain a construction general permit (NOI) from the Regional Water Quality Control Board to discharge stormwater, and to develop and implement stormwater pollution prevention plans. b. The project developer shall submit a Stormwater Pollution Prevention Plan (SWPPP) to the City Engineer/Chief Building Official for review and approval prior to the issuance of a grading or building permit, whichever is sooner. A copy of the approved SWPPP, including all approved amendments, shall be available at the project site for City review until all engineering and building work is complete and City permits have been finaled. A site specific SWPPP must be combined with proper and timely installation of the BMPs, thorough and frequent inspections, maintenance, and documentations. SWPPP for projects shall be kept up to date with the projects' progress. Failure to comply with the most updated construction SWPPP may result in the issuance of correction notices, citations, and/or stop work orders. c. The project developer is responsible for implementing the following BMPs. These, as well as any other applicable measures, shall be included in the SWPPP and implemented as approved by the City. i. The project developer shall include erosion control/stormwater quality measures on the project grading plan which shall specifically address measures to prevent soil, dirt, and debris from entering the public storm drain system. Such measures may include, but are not limited to, hydroseeding, hay bales, sandbags, and siltation fences and shall be subject to the review and approval of the City Engineer/Chief Building Official. If no grading plan is required, necessary erosion control/stormwater quality measures shall be shown on the site plan submitted for a building permit, and shall be subject to the review and approval of the Building and Safety Division. The project developer is responsible for ensuring that the contractor is aware of and implements such measures. ii. All cut and fill slopes shall be revegetated and stabilized after completion of grading, but in no case later than October 15. Hydroseeding shall be accomplished before September 15 and irrigated with a temporary irrigation system to ensure that the vegetated areas are established before October 15. 25
