On February 21, 2001 The San Diego Regional Water Quality Control Board (Regional Board) issued the Municipal Storm Water Permit Order 2001-01 (Municipal Permit) to control waste discharges in urban runoff from the Municipal Separate Storm Sewer Systems (MS4) that drain into the watersheds of the County of San Diego, incorporated cities of San Diego County and the San Diego Unified Port District (jointly referred to as “Copermittees”). In part, the Municipal Permit requires that the Jurisdictions within a watershed (“Watershed Copermittees”) collaborate on the development of a Watershed Urban Runoff Management Plan (WURMP) for each watershed, which addresses high priority stormwater quality issues found within the various watersheds. The Copermittees jointly developed Final WURMP Model Guidance to be used to facilitate the development of WURMPs, for nine (9) watersheds, and also developed a Unified WURMP Document that addresses common program components. 
 
The WURMPs prepared by each Watershed Copermittee Workgroup were completed on January 31, 2003, and submitted to the Regional Water Quality Control Board. As required by the Municipal Permit, each subsequent year, the Copermittees are required to prepare an Annual Report, which outlines what progress has been made in the implementation of the programs outlined in each WURMP. The following Table provides links to information about the programs for each of the nine watersheds, and the responsible agencies involved in their preparation:
