	Corps of Engineers and Its Civil Works Program

The U.S. Army Corps of Engineers (Corps) is an agency in the Department of Defense that has military and civilian responsibilities. Under its civil works program at the direction of Congress, the Corps plans, constructs, operates, and maintains a wide range of water resources projects. The Corps' oldest civil responsibilities are creating navigable channels and flood control projects. Environmental infrastructure refers to municipal water and wastewater facilities. Once authorized, appropriations for Corps studies are sought through the annual Energy and Water Development Appropriations Acts. Project Cost-Sharing

How to allocate the cost of Corps projects among non-federal sponsors and the federal government has been debated for decades. These legislative changes have given the Corps environmental responsibility beyond its traditional water resources development projects.
At the direction of Congress primarily through Water Resources Development Acts (WRDAs), the U.S. Army Corps of Engineers (an agency within the Department of Defense) undertakes water resources projects. The agency's civil works mission has expanded beyond its original responsibility of improving and maintaining navigable channels; the mission now includes flood control, emergency and disaster response, environmental restoration, municipal water infrastructure, and other activities. The non-federal sponsors and the federal government (primarily through the annual Energy and Water Development Appropriations Acts) share the cost of most Corps projects and activities. This report outlines the agency's organization, project development process, civil works appropriations, and evolution of its responsibilities.
