County of San Diego's Watershed Protection Ordinance and Standards Manual (Revised May, 2013)

On May 8, 2013, the San Diego Regional Water Quality Control Board adopted a new Municipal Stormwater Permit (National Pollution Discharge Elimination System Permit, No. R9-2013-0001).  This Permit mandates that the County of San Diego develop new and updated Urban Runoff Management Programs and submit them to the Regional Board within two years of Permit adoption.  Permit requirements are generally implemented in the unincorporated County under authority of the Watershed Protection, Stormwater Management, and Discharge Control Ordinance (WPO).  The current version of the WPO will remain in effect until an updated version is adopted.  We currently expect that this will occur by mid-2015.  Some construction and development-related provisions of the County’s programs are also implemented through the San Diego County Grading Ordinance.
