Army Corps of Engineers: Water Resource Authorization and Project Delivery Processes [June 1, 2018] [open pdf - 1MB]
From the Document: "The U.S. Army Corps of Engineers (USACE) in the Department of Defense undertakes water resources development activities. Its projects primarily are to maintain navigable channels, reduce flood and storm damage, and restore aquatic ecosystems. Congress directs USACE through authorizations and appropriations legislation. This report summarizes authorization legislation, the standard project delivery process, authorities for alternative water resource project delivery, and other USACE authorities. Authorization Legislation. Congress generally authorizes USACE water resource activities in authorization legislation prior to funding them through appropriations legislation. USACE's ability to act on an authorization often is determined by funding. Congress typically authorizes numerous new USACE site-specific activities and provides policy direction in an omnibus USACE authorization bill, typically titled a Water Resources Development Act (WRDA). Most project-specific authorizations in WRDAs fall into three general categories: project studies, construction projects, and modifications to existing projects. A few provisions in WRDA bills have time-limited authorizations; therefore, some WRDA provisions may be reauthorizing expired or expiring authorities. In 2018, USACE identified a $96 billion backlog of authorized construction projects."
