County of San Diego's Watershed Protection Ordinance (Revised May, 2015)
 

On May 8, 2013, the San Diego Regional Water Quality Control Board  (Regional Board) adopted a new Municipal Stormwater Permit (National Pollution Discharge Elimination System Permit, No. R9-2013-0001), and subsequently adopted R9-2015-0001 on February 11, 2015, which amended the order.  This Permit mandates that the County of San Diego develop new and updated Runoff Management Plans and Programs, including Water Quality Improvement Plans and a Jurisdictional Runoff Management Program. These documents were submitted to the Regional Board on June 26, 2015.  Permit requirements are generally implemented in the unincorporated County under authority of the Watershed Protection, Stormwater Management, and Discharge Control Ordinance (WPO).   

On May 13, 2015 the County Board of Supervisor’s adopted the Watershed Protection, Stormwater Management, and Discharge Control Ordinance (WPO) which is updated to reflect current Stormwater Permit requirements. The WPO became effective June 12, 2015.
