Army Corps Supplemental Appropriations: History, Trends, and Policy Issues [December 21, 2017] [open pdf - 784KB]
"Congress directs the U.S. Army Corps of Engineers (Corps) to plan and build water resource facilities through the agency's civil works program. The Corps also has a prominent role in responding to natural disasters, especially floods, in U.S. states and territories. In recent years through supplemental appropriations, Congress also has funded the agency to study and construct projects that reduce flood risks in areas recently affected by some hurricanes and floods. [...] A common issue for Congress after a flood-related disaster is whether to provide supplemental funds directly to the Corps and, if so, how much and for which Corps activities. During its deliberations on recent supplemental appropriations bills, Congress also has considered whether to maintain requirements for nonfederal cost sharing, what requirements to include regarding reporting to Congress and public transparency associated with supplemental funds, and what type of flood damage-reduction efforts to support (e.g., repair of existing infrastructure, construction of new infrastructure). [...] From 2005 to 2016, Congress appropriated $31.4 billion in supplemental funding to the Corps; these funds amounted to more than half of the agency's annual discretionary appropriations over that same period. Of the $31.4 billion, $27.2 billion (87%) was for responding to flooding and other natural disasters."
