General Information

Colusa Basin Mitigation Bank is a 160-acre site located as a subset of a 215-acre property in Colusa County. The property shares borders on three sides with wetlands managed for wildlife habitat, including the giant garter snake. Directly adjacent to the property is the Colusa National Wildlife Refuge which supports a well-documented population of the giant garter snake.

The bank is approved by the U.S. Army Corps of Engineers, the U.S. Environmental Protection Agency, the U.S. Fish and Wildlife Service, and the California Department of Fish and Wildlife to provide mitigation credits to offset impacts to the giant garter snake and 404 seasonal wetlands.
