The Corps conducts its emergency response activities under two basic authorities -- the Flood Control and Coastal Emergency Act , and the Stafford Disaster Relief and Emergency Assistance Act
Stafford Disaster Relief and Emergency Assistance Act

The Robert T. Stafford Disaster Relief and Emergency Assistance Act is a United States federal law designed to bring an orderly and systemic means of federal natural disaster assistance for state and local governments in carrying out their responsibilities to aid citizens....
 . 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.

Infrastructure Support


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 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.

Water 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 law
    Federal law

    Federal law is the body of law created by the federal government of a country. A federal government is formed when a group of political units, such as state or provinces join together in a federation, surrendering their individual sovereignty and many powers to the central government while retaining or reserving other limited powers....
    s in 1824 authorizing the Corps to improve safety on the Ohio and Mississippi Rivers and several ports. Today, the Corps maintains more than 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 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
    Flood Control Act of 1936

    The Flood Control Act of 1936, , was an Act of Congress signed into law by President of the United States Franklin D. Roosevelt on 22 June 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
    Washington Aqueduct

    The Washington Aqueduct is an aqueduct that provides the public water supply system serving Washington, D.C. and parts of its suburbs.

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

, 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

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.

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 that caused flooding of 80% of the city of New Orleans.

Review of Corps of Engineers' projects has also been criticized for its lack of impartiality. The investigation of levee failure in New Orleans during Hurricane Katrina was sponsored by ASCE but funded by the Corps of Engineers and involved its employees.

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

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 in size.
