Santa Margarita Water Quality Improvement Plan
Agencies involved in the development of the Santa Margarita Water Quality Improvement Plan (WQIP) include the California Department of Transportation, the County of Riverside, the Riverside County Flood Control and Water Conservation District, the County of San Diego, and Cities in Riverside County – Menifee, Murrieta, Temecula and Wildomar. 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 Santa Margarita Water Quality Improvement Plan is in its development stages. To follow along with WQIP progress, please refer to the Santa Margarita Regional Clearinghouse.

Santa Margarita 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. The Santa Margarita Watershed Management Area Analysis is currently undergoing discussion.
All data that were used to develop the WQIP but do not fit into one of the above categories can be found in the document archive.
