Under which two basic authorities does US ACE conduct its emergency response activities?

The U.S. Army Corps of Engineers (USACE) conducts its emergency response activities primarily under two authorities: the Robert T. Stafford Disaster Relief and Emergency Assistance Act, which allows for federal assistance in disaster response and recovery, and the Flood Control Act of 1941, which authorizes the Corps to undertake projects for flood control and emergency response. These authorities enable USACE to provide critical support in times of natural disasters, including flood response, recovery efforts, and infrastructure rehabilitation.
