Who We Are

The Los Angeles District provides civil works and military engineering support to Southern California, Nevada, Arizona, and parts of Utah. The area encompasses 226,000 square miles, 420 miles of coastline, 14 harbors, and the highest, lowest, and hottest spots in the contiguous 48 states. The scope of missions in the district vary from supporting the world’s largest groundwater recharge system in Orange County, Calif., to our involvement in one of the nation’s most significant transportation projects, the California High-Speed Rail.

Among the 14 navigation projects and 13 miles of breakwaters maintained by the district are the Ports of Los Angeles and Long Beach which account for a majority of West Coast trade and shipping.

Major flood-control projects include improvements to Prado Dam and the Santa Ana River Mainstem Project in Southern California.

The district is responsible for the operation and maintenance of 16 dams and 54 miles of flood control channels. The dams and recreation areas host more than 7 million visitors a year.

Military missions at nine installations include construction of a hospital at Fort Irwin, Calif., and F-35 fighter jet facilities at Luke Air Force Base, Ariz.

Ecosystem restoration projects form a major part of the district’s workload. These include the Tres Rios project in the heart of Phoenix and Los Angeles River projects and studies, focused on water quality improvements and passive recreation opportunities along portions of these rivers.

The Interagency and International Support program allows the district to do work for other federal agencies by tailoring program support capabilities to customer requirements and budget. Major projects include construction of the border fence for DHS and rehabilitation of infrastructure at VA facilities.
