San Diego River Water Quality Improvement Plan
Agencies involved in the development of the San Diego River Water Quality Improvement Plan (WQIP) include the Cities of El Cajon, La Mesa, Santee, San Diego, the County of San Diego, and the California Department of Transportation. The WQIP is a requirement of updated stormwater regulations adopted by the Regional Water Quality Control Board (Regional Board) according to Order No. R9-2013-0001, as amended by Order Nos. R9 2015-0001 and R9-2015-0100. The ultimate goal of the WQIP is to protect, preserve, enhance, and restore water quality of receiving water bodies. These improvements in water quality will be accomplished through an adaptive planning and management process that identifies the highest priority water quality conditions within the watershed and implements strategies to address them.
The San Diego River Water Quality Improvement Plan was originally submitted to the Regional Board on June 26, 2015, as required by the Municipal Permit. The WQIP was subsequently revised and resubmitted in order to incorporate comments received from the public and the Regional Board. Following further comments, the Regional Board issued an acceptance letter for the San Diego River WQIP on February 12, 2016. The resulting WQIP, appendices, and acceptance letter are available at the links below:

For Copermittee contact information, please check out the San Diego River Stakeholders page.
As part of the adaptive management process and in order to discuss watershed-wide goals, strategies, and issues, Copermittees hold monthly workgroup meetings that are also open to the public. These meetings, along with their agendas, meeting summaries, and meeting materials, are linked to below. For additional current events pertaining to the San Diego River WMA, please see the San Diego River WMA Calendar.

Water Quality Data
Monitoring data used in the development of the WQIP can be found on the California Environmental Data Exchange Network (CEDEN) website, www.ceden.org.
Geographic Information System (GIS) Data
These shapefiles were used for mapping purposes to support the development of the San Diego River Watershed Management Area Water Quality Improvement Plan (WQIP) dated 2013. Data presented reflect information available at the time of map creation. Data in these shapefiles may have been modified since that time.
The data represented in the subject GIS digital data files is to be used for general information purposes only. The dimensions and alignments of boundaries of mapping units in these files are approximations only, and should not be considered authoritative or sufficient for determining the location or extent of the subject mapped features.
Available GIS data, layers, and/or shapefiles used to develop the maps generated by the Copermittees for the Water Quality Improvement Plans and Annual Reports can be accessed with the original documents.

San Diego River Watershed Management Area Analysis (WMAA) Data
Typically, the WMAA is presented as an appendix to each watershed’s WQIP; however, there is also a regional component to the WMAA. For the Regional WMAA, please check out our regional efforts.
