New Stormwater Permit Requirements

Under the federal Clean Water Act, the City of San Diego and other municipalities in the region are mandated to obtain National Pollutant Discharge System (NPDES) permits for discharges of urban runoff from their municipal storm drain system. Starting on Dec. 2, 2002, the City of San Diego had established the Storm Water Standards Manual to provide guidance on the required water quality improvements for new development and redevelopment projects, and the required construction Best Management Practices (BMPs). On January 24, 2007, the Regional Water Quality Control Board had adopted Order No. R9-2007-01, which renews the municipal NPDES permit, and changes some of the requirements for water quality improvements and construction BMPs. These updated requirements are reflected in the January 2011 update of the Storm Water Standards Manual (PDF). An updated Storm Water Requirements Applicability Checklist (PDF - Form Filler) is also available on this site. Information on when the updated requirements will apply to projects currently under review is found in the Introduction section of the updated manual.
