The Soquel Canyon Mitigation Bank is a 313 acre property located predominately within the City of Chino Hills in San Bernardino County, with a few acres located in unincorporated Orange County.

The property’s southern boundary is the Chino Hills State Park, a premier natural open space area in the hills of Santa Ana Canyon near the junction of San Bernardino, Orange, Riverside and Los Angeles Counties. The Park is a critical link in the Puente-Chino Hills biological corridor, encompassing over 14,000 acres of oaks, sycamores, and rolling grassy hills stretching nearly 31 miles from the Santa Ana Mountains to the Whittier Hills. The property offers a great diversity of vegetation; its canyons support riparian areas which protect water quality and provide suitable habitat for numerous wildlife species including least bell’s vireo and California coastal gnatcatcher. The black walnut trees in low-lying riparian areas join coast live oaks to form mixed walnut woodlands in and adjacent to the creeks.

A variety of scrub and chaparral communities are found on the drier slopes including coastal sage scrub, another sensitive community. Coastal sage scrub is one of the most threatened natural communities in California and is known to support numerous special status plant and wildlife species, including populations of the sensitive coast horned lizard and red-diamond rattlesnake.

Service Area

The Soquel Canyon Mitigation Bank will provide CEQA mitigation for projects impacting sensitive habitats throughout portions of Orange, San Bernardino, Riverside, and Los Angeles Counties as well as portions of the San Jacinto River, Seal Beach, Newport Bay, and Aliso Creek watersheds. The Bank can also provide Army Corps’ mitigation for projects impacting wetlands/waters within the San Gabriel, Santa Ana, and Lower Los Angeles watersheds.
