Established in 1888, the South Pacific Division is one of the Corps' nine regions nationwide.
Four operating Districts, headquartered in Los Angeles, Sacramento, San Francisco and Albuquerque, provide federal and military engineering support in California, Arizona, Nevada, Utah, New Mexico and in parts of Colorado, Oregon, Idaho, Wyoming and Texas.
The civil works program is oriented around major regional watersheds and leverages federal resources for navigation, flood damage reduction and ecosystem restoration. Major river basins include the Sacramento, San Joaquin, Santa Ana, Colorado and Rio Grande, which are governed by complex water rights. Water resources are vital to agriculture, urban development, natural ecosystems, Tribal interests, and recreation.
There are more than 300 threatened and endangered species in the region. We issue regulatory permits under the Clean Water Act for development in the nation's waters and wetlands, balancing environmental stewardship with the need for economic and urban growth. The Corps works in partnership with other federal agencies, state governments and local communities on collaborative solutions to these complex water resource issues.
