The United States Army Corps of Engineers (USACE) is a federal agency and a major Army command made up of some 34,600 civilian and 650 military personnel, making it the world's largest public engineering, design and construction management agency. Although generally associated with dams, canals and flood protection in the United States, USACE is involved in a wide range of public works support to the nation and to Department of Defense throughout the world.
The Corps's mission is to provide military and public works services to the United States by providing vital engineering services and capabilities, as a public service, across the full spectrum of operations--from peace to war--in support of national interests. Their most visible missions include
- Planning, designing, building, and operating locks and dams. Other civil engineering projects include flood control, beach nourishment, and dredging for waterway navigation.
- Design and construction of flood protection systems (as in New Orleans) through various federal mandates (see Public Laws below).
- Design and construction management of military facilities for the Army and Air Force and other Defense and Federal agencies.
- Environmental regulation and ecosystem restoration.
USACE provides support directly and indirectly to the warfighting effort. The Corps builds and helps maintain much of the infrastructure the Army and the Air Force use to train, house, and deploy troops. Corps built and maintained navigation systems and ports provide an effective means to deploy vital equipment and other materiel. Corps R&D facilities help develop new methods and measures for deployment, force protection, terrain analysis, and mapping, and other support.
USACE directly supports the military at the front, making expertise available to commanders to help solve and avoid engineering and other problems. Forward Engineer Support Teams may accompany combat engineers to provide immediate support, or to reach back electronically into the rest of the Corps for the necessary expertise. Corps professionals use the knowledge and skills honed on both military and civil projects to support the US and local communities in the areas of real estate, contracting, mapping, construction, logistics, engineering, and management experience. This work currently includes support for rebuilding Iraq, establishing Afghanistan infrastructure, and supporting international and interagency services.
In addition, the work of almost 34,000 civilians on civil works programs throughout USACE provide a training ground for similar capabilities world-wide. USACE civilians volunteer for assignments world-wide. For example, hydropower experts have helped repair, renovate, and run hydropower dams in Iraq in an effort to help get Iraqis to become self-sustaining.
USACE supports the United States' Department of Homeland Security
and the Federal Emergency Management Agency
(FEMA) through its security planning, force protection, research and development, disaster
preparedness efforts, and quick response to emergencies and disasters. The Corps of Engineers is able to help save hundreds of lives and millions of dollars in property damage every year from natural and manmade disasters (however, see Civil Works controversies below).
The Corps conducts its emergency response activities under two basic authorities -- the Flood Control and Coastal Emergency Act (P.L. 84-99), and the Stafford Disaster Relief and Emergency Assistance Act (P.L. 93-288). In a typical year, the Corps of Engineers responds to more than 30 Presidential disaster declarations, plus numerous state and local emergencies. Emergency responses usually involve cooperation with other military elements and Federal agencies in support of State and local efforts.
Work comprises engineering and management support to military installations, global real estate support, civil works support (including risk and priorities), operations and maintenance of Federal navigation and flood control projects, and monitoring of dams and levees.
More than 67 percent of the goods consumed by Americans and more than half of the Nation's oil imports are processed through deepwater ports maintained by the Corps of Engineers, which maintains more than of commercially navigable channels across the US.
In both its Civil Works mission and Military Construction program, the Corps is responsible for billions of dollars of the nation's infrastructure. For example, the Corps maintains direct control 609 dams, maintains and/or operates 257 navigation locks, and operates 75 hydroelectric facilities generating 24% of the nation's hydropower and three percent of its total electricity. USACE inspects over 2,000 Federal and non-Federal levees every two years.
Four billion gallons of water per day are drawn from the Corps' 136 multi-use water supply projects comprising 9.8 million acre-feet of water storage, making it one of the United States' largest water supply agencies.
The 249th Engineer Battalion (Prime Power), the only active duty unit in USACE, generates and distributes prime electrical power in support of warfighting, disaster relief, stability and support operations as well as provides advice and technical assistance in all aspects of electrical power and distribution systems. The battalion deployed in support of recovery operations after 9/11 and was instrumental in getting Wall Street back up and running within a week. The battalion also deployed in support of post-Katrina operations.
All of this work represents a significant investment in the nation's resources.
Through its Civil Works program, USACE carries out a wide array of projects that provide coastal protection, flood protection, hydropower, navigable waters and ports, recreational opportunities, and water supply. Work includes coastal protection and restoration, including a new emphasis on a more holistic
approach to risk management. As part of this work, the Corps is the number one provider of outdoor recreation in the US, so there is a significant emphasis on water safety.
Army involvement in works "of a civil nature," including water resources, goes back almost to the origins of the U.S. Over the years, as the Nation's needs have changed, so have the Army's Civil Works missions.
Major areas of emphasis include the following:
- Navigation. Supporting navigation by maintaining and improving channels was the Corps of Engineers' earliest Civil Works mission, dating to Federal laws in 1824 authorizing the Corps to improve safety on the Ohio and Mississippi Rivers and several ports. Today, the Corps maintains more than 12,000 miles (19,200 km) of inland waterways and operates 235 locks. These waterways -a system of rivers, lakes and coastal bays improved for commercial and recreational transportation - carry about 1/6 of the Nation's inter-city freight, at a cost per ton-mile about 1/2 that of rail or 1/10 that of trucks. USACE also maintains 300 commercial harbors, through which pass 2 billion tons of cargo a year, and more than 600 smaller harbors.
- Flood Damage Reduction. The Corps was first called upon to address flood problems along the Mississippi river in the mid- 1800s. They began work on the Mississippi River and Tributaries Flood Control Project in 1928, and the Flood Control Act of 1936 gave the Corps the mission to provide flood protection to the entire country. Neither the Corps nor any other agency can prevent all flood damages; and when floods cause damage, there is sure to be controversy (see "Civil Works Controversies" below).
- Recreation. The Corps of Engineers is the Nation's largest provider of outdoor recreation, operating more than 2,500 recreation areas at 463 projects (mostly lakes) and leasing an additional 1,800 sites to State or local park and recreation authorities or private interests. The Corps hosts about 360 million visits a year at its lakes, beaches and other areas, and estimates that 25 million Americans (one in ten) visit a Corps project at least once a year. Supporting visitors to these recreation areas generates 600,000 jobs.
- Hydroelectric Power. The Corps was first authorized to build hydroelectric plants in the 1920s, and today operates 75 power plants, producing one fourth of the nation's hydro-electric power--or three percent of its total electric energy. This makes USACE the Nation's fifth largest electric supplier.
- Shore Protection. With a large proportion of the U.S. population living near our sea and lake shores, and an estimated 75% of U.S. vacations being spent at the beach, there has been Federal interest – and a Corps of Engineers mission - in protecting these areas from hurricane and coastal storm damage. This mission is one of the more controversial missions of USACE (see "Civil Works Controversies" below).
- Dam Safety. The Corps of Engineers is a leader in developing engineering criteria for safe dams, and conducts an active inspection program of its own dams.
- Water Supply. The Corps first got involved in water supply in the 1850s, when they built the Washington Aqueduct. Today USACE reservoirs supply water to nearly 10 million people in 115 cities. In the drier parts of the Nation, water from Corps reservoirs is also used for agriculture.
The U.S. Army Corps of Engineers environmental mission has two major focus areas: restoration and stewardship. The Corps supports or manages numerous environmental programs, that run the gamut from cleaning up areas on former military installations contaminated by hazardous waste or munitions to helping establish/reestablish wetlands that helps endangered species survive.Some of these programs include Ecosystem Restoration, Formerly Used Defense Sites, Environmental Stewardship, EPA Superfund, Abandoned Mine Lands, Formerly Utilized Sites Remedial Action Program, Base Realignment and Closure, 2005, and Regulatory.
This mission includes education as well as regulation and cleanup.
The U.S. Army Corps of Engineers has a very active environmental program under both its Military and Civil Programs.
The Civil Works environmental mission that ensures all Corps projects, facilities and associated lands meet environmental standards. The program has four functions: compliance, restoration, prevention, and conservation. The Corps also regulates all work in wetlands and waters of the United States.
The Military Programs Environmental Program manages design and execution of a full range of cleanup and protection activities:
- cleans up sites contaminated with hazardous waste, radioactive waste, or ordnance
- complies with federal, state, and local environmental laws and regulations
- strives to minimize our use of hazardous materials
- conserves our natural and cultural resources
The following are major areas of environmental emphasis:
- Wetlands and Waterways Regulation and Permitting
- Ecosystem Restoration
- Environmental Stewardship
- Radioactive site cleanup through the Formerly Used Sites Remedial Action Program (FUSRAP)
- Base Realignment and Closure (BRAC)
- Formerly Used Defense Sites (FUDS)
- Support to EPA's Superfund Program
See also Environmental Enforcement below.
The history of United States Army Corps of Engineers can be traced back to 16 June 1775, when the Continental Congress organized an army with a chief engineer and two assistants. Colonel Richard Gridley became General George Washington's first chief engineer; however, it was not until 1779 that Congress created a separate Corps of Engineers. One of its first tasks was to build fortifications near Boston at Bunker Hill. The first Corps was mostly composed of French subjects, who had been hired by General Washington from the service of Louis XVI.
The Corps of Engineers as it is known today came into being on 16 March 1802, when President Thomas Jefferson was authorized to "organize and establish a Corps of Engineers ... that the said Corps ... shall be stationed at West Point in the State of New York and shall constitute a Military Academy." The United States Military Academy was under the direction of the Corps of Engineers until 1866. The Corps's authority over river works in the United States began with its fortification of New Orleans after the War of 1812. A Corps of Topographical Engineers, was separately authorized on 4 July 1838, consisted only of officers, and was used for mapping and the design and construction of federal civil works such as lighthouses and other coastal fortifications and navigational routes. It included such officers as George Meade. It was merged with the Corps of Engineers on 31 March 1863, at which point the Corps of Engineers also assumed the Lakes Survey District mission for the Great Lakes. In the mid-1800s, Corps of Engineers' officers ran Lighthouse Districts in tandem with US Naval officers.
The Army Corps of Engineers played an instrumental role in the American Civil War. Many of the men who would serve in the top leadership in this institution were West Point graduates, who rose to military fame and power during the Civil War. Some of these men were Union Generals George McClellan, Henry Halleck, George Meade, and Confederate generals Robert E. Lee, Joseph Johnston, and P.G.T. Beauregard. The versatility of officers in the Army Corps of Engineers contributed to the success of numerous missions throughout the Civil War. They were responsible for building pontoon and railroad bridges, forts and batteries, the destruction of enemy supply lines, and the construction of roads. The Union forces were not the only ones to employ the use of engineers throughout the war; and on March 6 1861, once the South had seceded from the Union, among the different acts passed at the time, a provision was stated that called for the creation of a Confederate Corps of Engineers.
The progression of the war demonstrated the South’s disadvantage in engineering expertise; because of the initial 65 cadets who resigned from West Point to accept positions with the Confederate Army, only seven were placed in the Corps of Engineers. To overcome this obstacle, the Confederate Congress passed legislation that gave a company of engineers to every division in the field; and by 1865, they actually had more engineer officers serving in the field of action than the Union Army. The Army Corps of Engineers served as a main function in making the war effort logistically feasible. One of the main projects for the Army Corps of Engineers was constructing railroads and bridges, which Union forces took advantage of because railroads and bridges provided access to resources and industry. One area where the Confederate engineers were able to outperform the North was in the ability to build fortifications that were used both offensively and defensively along with trenches that made them harder to penetrate. This method of building trenches was known as the zigzag pattern.
From the beginning, many politicians wanted the Corps to contribute to both military construction and works of a civil nature. Assigned the military construction mission on 1 December 1941 after the Quartermaster Department struggled with the expanding mission, the Corps built facilities at home and abroad to support the U.S. Army and Air Force. During World War II the mission grew to more than 27,000 military and industrial projects in a $15.3 billion mobilization program. Included were aircraft, tank assembly, and ammunition plants, camps for 5.3 million soldiers, depots, ports, and hospitals, as well as the Manhattan Project, and the Pentagon.
In the 20th century, the Corps became the lead federal flood control agency and significantly expanded its civil works activities, becoming among other things, a major provider of hydroelectric energy and the country’s leading provider of recreation; its role in responding to natural disasters also grew dramatically. In the late 1960s, the Corps became a leading environmental preservation and restoration agency.
Five commanding general /Chiefs of Staff (after the 1903 reorganization) of the United States Army held Engineer commissions early in their careers. All transferred to other branches before rising to the top. They were Alexander Macomb, George B. McClellan, Henry W. Halleck, Douglas MacArthur, and Maxwell D. Taylor.
Notable dates and projects
Occasional civil disasters including the Great Mississippi Flood of 1927 resulted in greater responsibilities for the Corps. New Orleans is another example of this.
The current Chief of Engineers
and Commanding General, U.S. Army Corps of Engineers is Lieutenant General Robert L. Van Antwerp, Jr.
Four Deputy Commanding Generals assist in supervising General Staff activities and in discharging the responsibilities which devolve upon the Commanding General. The current Deputies are:
- Major General Don T. Riley, Deputy Commanding General.
- Major General Steven R. Abt, Deputy Commanding General for Mobilization and Reserve Affairs (Individual Mobilization Augmentee)
- Major General Merdith (Bo) Temple, Deputy Commanding General for Civil and Military Operations
- Brigadier General Jeffrey J. Dorko, Deputy Commanding General for Military and International Operations
The Headquarters group defines policy and guidance and plans direction for the organizations within the Corps. It is made up of an Executive Office and 17 Staff Principals. Located in Washington, DC
, the Headquarters creates policy and plans the future direction of all other Corps organizations.
USACE has two directors who head up Military Programs and Civil Works.
- Steve Stockton, Director of Military Programs.
- Joe Tyler, Director of Civil Works
The current USACE Command Sergeant Major is Robert A. Winzenried.
Divisions and Districts
The U.S. Army Corps of Engineers is organized geographically into eight permanent divisions, one provisional division, one provisional district, and one research command reporting directly to the HQ. Within each division, there are several districts. Districts are defined by watershed
boundaries for civil works projects and by political boundaries for military projects.
- Great Lakes and Ohio River Division (LRD), located in Cincinnati, OH. Stretches from the St Lawrence Seaway, across the Great Lakes, down the Ohio River Valley to the Tennessee and Cumberland Rivers. Covers , parts of 17 states. Serves 56 million people. Its seven Districts are located in Buffalo NY, Chicago IL, Detroit MI, Louisville KY, Nashville TN, Pittsburgh PA, and Huntington, WV. The division commander serves on two national and international decision-making bodies: co-chair of the Lake Superior, Niagara, and Ontario/St Lawrence Seaway boards of control; and the Mississippi River Commission.
- Mississippi Valley Division (MVD), located in Vicksburg, MS. Stretches from Canada to the Guf of Mexico. Covers , and portions of 12 states bordering the Mississippi River.

- 412th Engineer Command, US Army Reserve, located in Vicksburg, MS.
- 416th Engineer Command, US Army Reserve, located in Darien, IL.
Some of the Corps of Engineers' civil works projects have been characterized in the press as being pork barrel or boondoggles such as the New Madrid Floodway Project and the New Orleans flood protection. Projects have allegedly been justified based on flawed or manipulated analyses during the planning phase. Some projects are said to have created profound detrimental environmental effects and/or provided questionable economic benefit such as the Mississippi River Gulf Outlet in southeast Louisiana. Faulty design and substandard construction have been cited in the failure of levees in the wake of Hurricane Katrina.
Corps of Engineers projects can be found in all fifty states, making its budget and project authorizations ripe for earmarks and other pork. Under the provisions of the US Constitution, Article I, Sec 9, "[N]o Money shall be drawn from the Treasury but in Consequence of an Appropriation made by Law. Therefore, Corps projects are either authorized specifically or as part of a Congressionally authorized category of projects. Many times, local citizen, special interest, and political groups lobby Congress for authorization and appropriations for specific projects in their area. Depending on the point of view of any debate on these projects is that they may or may not be considered sound from an engineering standpoint. Whether or not USACE planners and engineers actually do the best they can with what they are directed to do is part of the controversy.
Attempts to modify the Corps' way of doing business or its organizational structure have most recently been championed by Senator Russ Feingold and Senator John McCain who succeeded in adding an amendment requiring peer review of corps projects to the Water Resources Development Act in 2006. That bill did not pass, but a similar bill, the Water Resources Development Act of 2007, with the Corps reform measures intact was passed by Congress in 2007 becoming law despite a presidential veto.
Some of the Corps of Engineers' military works projects of the past have been criticized as being deleterious to the environment. A number of camps and facilities designed by the Corps of Engineers, including the former Camp O'Ryan
in New York State, have had an unintended or negative impact on the surrounding communities. Camp O'Ryan, with its rifle range
, has possibly contaminated well and storm runoff water with toxic lead
. This runoff water eventually runs into the Great Lakes
, the source of drinking water to millions of people. This situation is exacerbated by a failure to locate the engineering and architectural plans for the camp, which were produced by the New York District in 1949.

Other Related Laws
One of the major responsibilities of the Corps of Engineers is administering the wetlands permitting program under Section 404 of the Federal Water Pollution Control Act of 1972. (aka "The Clean Water Act
"). This Act authorized the Secretary of the Army to issue permits for the discharge of dredged and fill material.
Section 10 of the Rivers and Harbors Act of 1899 (codified in Chapter 33, Section 403 of the United States Code) gave the Corps authority over navigable waters of the United States. As navigable waters are defined as "navigable waters of the United States are those waters that are subject to the ebb and flow of the tide and/or are presently being used, or have been used in the past, or may be susceptible for use to transport interstate or foreign commerce", the Corps has broad authority to enforce this, including licensing of bridges over navigable waters, and the maintenance of pierhead and bulkhead lines.
There are three types of permits issued by the Corps of Engineers: Nationwide, Regional General, and Individual. 80% of the permits issued are nationwide permits, which include several general types of activities, as published in the Federal Register. To gain authorization under a nationwide permit, an applicant usually needs only send a letter to the regional Corps office notifying them of his or her intent, type and amount of impact, and a site map. Although the nationwide process is fairly simple, Corps approval must be obtained before commencing with any work. Regional general permits are specific to each Corps division office. Individual permits are generally required for projects greater than 0.5 acres (2,000 m²) in size.

The Corps of Engineers branch insignia, the Corps Castle, is believed to have originated on an informal basis. In 1841, cadets at West Point wore insignia of this type. In 1902, the Castle was formally adopted by the Corps of Engineers as branch insignia. The castle itself is actually the Bradley Barracks at USMA in West Point, NY.
A current tradition was established with the "Gold Castles" branch insignia of General of the Army Douglas MacArthur, West Point Class of 1903, who served in the Corps of Engineers early in his career and had received the two pins as a graduation gift of his family. In 1945, near the conclusion of World War II, General MacArthur gave his personal pins to his Chief Engineer, General Leif J. Sverdrup. On May 2, 1975, upon the 200th anniversary of the Corps, retired General Sverdrup, who had civil engineering projects including the landmark -long Chesapeake Bay Bridge-Tunnel to his credit, presented the Gold Castles to then-Chief of Engineers Lieutenant General William C. Gribble, Jr., who had also served under General MacArthur in the Pacific. General Gribble then announced a tradition of passing the insignia along to future Chiefs of Engineers, and it has been done so since.
