About Us
The San Gabriel and Lower Los Angeles Rivers and Mountains Conservancy (RMC) was created by the California legislature in 1999. We’re one of ten conservancies within the
California Resources Agency. Our mission is to preserve open space and habitat in order to provide for low-impact recreation and educational uses, wildlife habitat restoration and protection, and watershed improvements within our jurisdictions. This work supports the public’s enjoyment and enhancement of recreational and educational experiences on public lands in a manner consistent with the protection of lands and resources in those watersheds.

Territory
RMC’s jurisdiction includes eastern Los Angeles County and western Orange County, comprised of the San Gabriel River Watershed and its tributaries, the Lower Los Angeles River Watershed and its tributaries, Upper Santa Clara River and its tributaries, the Dominguez Channel watershed, northern slope of the Angeles National Forest, the San Gabriel Mountains National Monument, Puente Hills and the San Jose Hills.

Policies
RMC’s overall policy guidelines are found in two key sources:
Public Resources Code Section 32600 (the enabling statute), and
Common Ground: From the Mountains to the Sea, the open space and watershed plan for the Los Angeles and San Gabriel Rivers. Capital funding is provided through voter-approved propositions.
Founding Legislation
In January 1999, Senator Hilda Solis introduced legislation to create a San Gabriel River Conservancy with no powers of condemnation or control over city zoning. After several revisions, the scope expanded to include the entire San Gabriel River Watershed and the Lower Los Angeles River. Solis’ bill and a companion bill from Assemblywoman Sally Havice were signed into law, forming the RMC, as codified in the
California Public Resources Code.
