Santa Margarita River Watershed Protection Program
The Santa Margarita River Watershed flows into the Santa Margarita River, passing through southwest portion of Riverside County (including areas of the Cities of Menifee, Murrieta, Wildomar, and unincorporated County of Riverside, and all of the City of Temecula) into San Diego County.
Stormwater runoff from these areas collects into Murrieta and Temecula creeks and combines to form the Santa Margarita River in Temecula. The Santa Margarita River flows through the “Gorge” and into San Diego County where it flows past Camp Pendleton into the Santa Margarita Lagoon at the Pacific Ocean. The Santa Margarita ‘Region’ is the portion of the Watershed that is within Riverside County.
Member Agencies

Benefit Assessments

The amount of benefit is computed based on parcel size (acreage) and use classification. The fee is referenced on property tax bills as “FLDCNTL Stormwater/clean water.”
