In the San Diego Bay Watershed, the Responsible Parties include the Cities of Chula Vista, Coronado, Imperial Beach, La Mesa, Lemon Grove, National City, and San Diego; the County of San Diego; the San Diego County Regional Airport Authority; and the San Diego Unified Port District. As of July 1, 2015, the City of Imperial Beach is the lead agency for the San Diego Bay watershed.
A new Water Quality Improvement Plan (WQIP) was developed in accordance with the requirements of the San Diego Regional Water Quality Control Board (Regional Board) Order No. R9-2013-0001, as amended by Order No. R9-2015-0001 (NPDES Permit #CAS0109266, Municipal Permit). The goal of the San Diego Bay WQIP is to protect, preserve, enhance, and restore water quality of receiving water bodies. This goal will be accomplished through an adaptive planning and management process that identifies the highest and focused priority water quality conditions within the watershed and implements strategies (jurisdiction-specific and/or watershed-level) to achieve improvements in the quality of discharges from the Responsible Parties' storm drain systems.

Watershed Management Area Analysis Files
A Watershed Management Area Analysis (WMAA) has been prepared for watersheds across San Diego County, including the San Diego Bay watershed. The WMAA for the San Diego Bay watershed, which includes the Pueblo, Sweetwater, and Otay Hydrologic Units, is included as part of the San Diego Bay WQIP appendices. A link to download the WMAA files is below.
A GIS file of critical coarse sediment areas is available at the regional WMAA page.
