Tijuana River Water Quality Improvement Plan
Agencies involved in the development of the Tijuana River Water Quality Improvement Plan (WQIP) include the Cities of Imperial Beach and San Diego in addition to the County of San Diego. 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 Tijuana River Water Quality Improvement Plan was originally submitted to the Regional Board in 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 with proposed amendments for the Tijuana River WQIP on February 12, 2016. The resulting WQIP, appendices, and acceptance letter are available at the links below:

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 Tijuana WMA, please see the Tijuana WMA Calendar.

Tijuana 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.
