From the Document: "Congress generally funds the civil works activities of the U.S. Army Corps of Engineers (USACE) in an annual Energy and Water Development appropriations act. These activities include the planning and construction of water resource projects and the operations and maintenance of infrastructure and navigation improvements managed by USACE (e.g., navigation channels). For USACE civil works, President Trump requested $4.8 billion for FY2020. As shown in Figure 1, Congress typically funds USACE above the President's request for the year (e.g., $7.0 billion for FY2019). This In Focus provides a primer on the USACE appropriations process for FY2020."
