Petersen Ranch

The Petersen Ranch Mitigation Bank, at over 4,000 acres, is the only bank in Los Angeles County, the largest bank in the State of California, and one of the largest banks in the United States. Situated within the boundaries of the proposed San Andreas Rift Zone Significant Ecological Area, it provides compensatory mitigation across a large part of Southern California.

The Bank is approved to provide mitigation for permitted impacts under US Army Corps of Engineers 404 permits, Regional Water Quality Control Board 401 certifications, and California Department of Fish & Wildlife 1600 agreements. It also provides CEQA/CESA mitigation for a wide variety of species and habitats.

Service Area

The bank drains into both the Santa Clara River and Antelope-Fremont Valley watersheds, resulting in an expansive wetland/riparian service area that includes portions of Los Angeles, Kern, Ventura, and San Bernardino Counties. Because the bank consists of two sites that are topographically and biologically diverse, it also provides a broad range of CEQA/CESA mitigation credits.

Please contact us if your project requires mitigation outside our service area.
