Redirecting Army Corps of Engineers Civil Works Resources During National Emergencies [January 28, 2019] [open pdf - 391KB]
"In January 2019, news outlets reported that the Trump Administration was investigating redirecting U.S. Army Corps of Engineers (USACE) civil works funds to construct physical barriers along the U.S.-Mexico border. USACE is an agency in the Department of Defense (DOD) that performs both military and civil works activities. Section 923 of the Water Resources Development Act of 1986 (WRDA 1986; 33 U.S.C. §2293) provides the Secretary of the Army authority to redirect civil works resources in the event of a declared war or national emergency that requires or may require use of the Armed Forces. [...] This CRS product provides a primer on the authority to redirect civil works resources, USACE civil works funding, and the legislative history of 33 U.S.C. §2293. It also discusses ways other than 33 U.S.C. §2293 that USACE has been or could be involved in wall or fence construction along the U.S.-Mexico border."
