The United States Army Corps of Engineers (USACE) delivers vital public and military engineering services to secure the Nation, energize the economy, and reduce disaster risk.  

USACE operates across two primary programs — Civil Works and Military Programs, spanning six core mission areas globally.

The Civil Works Program maintains 12,000 miles of commercial navigation channels and 926 harbors, operates over 600 dams, manages flood and storm damage reduction along the nation’s coastlines as well as along inland waterways. The Civil Works Program also works to balance the needs of the nation with those of the environment through the regulatory permitting program.

Additionally, USACE, as part of the National Response Framework, deploys personnel to assist in disaster response and recovery efforts, providing rapid public works and engineering support, which includes temporary emergency power, debris removal, temporary roofing and critical infrastructure assessments. Under its own authorities, USACE provides flood-fighting and coastal/shore protection assistance.

The USACE Military Program provides premier engineering, construction, real estate, stability operations, and environmental management products and services for the Army, Air Force, other assigned U.S. Government agencies and foreign governments. The USACE workforce is spread across the country and in 110 foreign countries, providing reimbursable engineering expertise throughout the world. The programs USACE executes in one-year can total over $20 billion and includes military construction projects on 280-plus installations as well as managing land title for over 36 million acres of real property for Army & Air Force installations and Army civil projects.
