The U.S. Army Corps of Engineers, Southwestern Division, headquartered in Dallas, Texas is a USACE Major Subordinate Command. The Division has served the region since 1937, overseeing hundreds of water resources development and military design and construction projects that bring value to our communities, our Nation and our Warfighters. The Division's team, which includes six District offices. Four within the southwestern U.S. region located in, Little Rock, Ark., Tulsa, Okla., and Fort Worth and Galveston, Texas. These districts provide diverse engineering and construction expertise and other services in all or part of six states covering some 2.3 million acres of public land and water, with an annual program totaling more than $2 billion.

On August 5, 2025, the USACE Transatlantic Division was stood down and its two districts, the Middle East District, and the Expeditionary District, continued operation under the authority of the Southwestern Division. The Southwestern Division continues to operate from the former Transatlantic Division’s headquarters offices in Winchester, Virginia. The Expeditionary District, which combined the contingency operations assets as one optimized command is headquartered in Kuwait.

As of the Transfer of Authority, the Southwestern Division now provides mission support to the U.S. Central Command within the USCENTCOM area of responsibility and U.S. Special Operations Command globally. Delivering the program through the Middle East District, and the Expeditionary District. 

In addition to the valuable contributions the Division provides each day to the warfighters and local communities it serves, SWD, known as the Pacesetters, supports emergency response and recovery efforts when hurricanes or other natural disasters occur, whether within or beyond its area of responsibility.

SWD was established on July 14, 1937, in Little Rock to manage large-scale construction projects authorized by the Flood Control Act of 1936. It moved to Dallas in 1941.  Most of SWD’s work falls into three major mission areas:   

• Civil Works, including flood risk management, navigation, hydropower, water supply, recreation, regulatory, and disaster relief.   
• Military Programs, including engineering, construction, and environmental management services for the Army and Air Force.   
• Interagency and International Services, which includes planning and engineering and construction management services for other federal, state and local agencies.
• Oversight of well over $5 billion in projects throughout the U.S. Central Command’s area of responsibility, as well as dedicated support to the U.S. Special Operations Command; and
• Combined dedicated and expeditionary district capabilities, partnering in peace and war, to deliver innovative, resilient, and sustainable solutions to the U.S. Department of Defense and the nation; and establishes the conditions for regional security and stability throughout the Middle East and Central Asia. 

OUR DISTRICTS (CONUS)

Fort Worth District established in 1950 after major Trinity River floods, manages water resource development for two-thirds of Texas and oversees military and interagency construction in Texas and Louisiana. Covering 140,000 square miles with over 1,200 employees, the district operates 25 reservoirs, three hydropower plants, and 350+ recreation areas, preventing over $155 billion in flood damages through FY23. Its mission spans flood risk management, water supply, environmental stewardship, and military construction at key bases. The district also supports federal agencies and leads national projects for Customs and Border Protection, while contributing to disaster response efforts like Hurricanes Harvey, Irma, and Maria.

Galveston District with its rich heritage in Texas history, the district plays a key role in America’s well-being by keeping waterways open for navigation and commerce and serves the nation as part of the world’s largest public engineering, design and construction management agency. Encompassing the Texas coast from Louisiana to Mexico - an area that spans across 50,000 square miles, includes 48 counties, two parishes and 16 congressional districts - the Galveston District successfully executes its mission of providing vital public engineering services in peace and war to strengthen our nation’s security, energize the economy and reduce risks from disasters. 

Little Rock District established in 1881, serves most of Arkansas and southern Missouri with both military and civil missions. As a full-spectrum engineering force of dedicated soldiers and civilians, the district supports service members and their families while developing and maintaining regional infrastructure. With unmatched expertise in planning, design, and construction, the district’s interdisciplinary team manages all phases of federal, state, and local projects. The district oversees nearly 750,000 acres of public land and water, helps preserve water quality, and produces enough hydroelectricity to power up to 400,000 households. Its projects have prevented over $7.5 billion in flood damage and support drinking water supply, navigation, and recreation. The district manages $6.5 billion in infrastructure, including 12 reservoirs, 13 navigation locks and dams, 7 hydroelectric plants, 146 public parks, and 308 miles of navigation channels. 

Tulsa District established in 1939, its civil works boundaries include Oklahoma and parts of southern Kansas and northern Texas. The district's Civil Works mission is one of the largest in the Corps of Engineers; it includes 38 multipurpose lakes which include five lock and dams on the McClellan-Kerr Arkansas River Navigation System. Although the primary purpose of district lakes is flood reduction, they also provide recreation, water supply, hydropower, navigation, and fish and wildlife habitat. The district's 150 miles of the MKARNS boasts the most inland, ice-free river port in America and provides waterway commerce to the heartland of the country. District projects have prevented billions of dollars in flood damages and the district's eight hydropower facilities provide about $52 million in annual sales. The district has 240 parks with more campsites -- 6,000-- than any other district in the Corps. The district’s military construction mission provides engineering and construction management services to two Army and four Air Force installations. During the last 10 years, the district has managed the design and construction of more than $1 billion in facilities for its military customers.

OUR DISTRICTS (OCONUS)

Middle East District executes seventy-five percent of the Division’s OCONUS program, providing design, construction execution, and related services and support to U.S. and allied mission partners in the U.S. Central Command area of responsibility to increase regional security and stability in support of enduring U.S. interests; on order, supports contingency operations. The district has field offices in nine countries in the Middle East.

Expeditionary District is structured specifically to provide speed of relevance project management, planning, engineering, design, environmental support, construction management, and real estate services within the U.S. Central Command’s area of responsibility; delivering cost effective, sustainable engineering solutions and services supporting contingency operations and peacetime efforts to strengthen the security and stability of our nation and our allied mission partners for years to come. Always Forward!
