During natural disasters, the U.S. Army Corps of Engineers Buffalo District Emergency Management Office conducts emergency operations to protect lives, alleviate suffering and remediate damage in accordance with Public Law (PL) 84-99 and PL 93-288.
PL 84-99 assistance includes flood response, post flood response, rehabilitation, advance measures and hazard mitigation.
PL 93-288 and the National Response Framework (NRF) provide authority for FEMA to task USACE with technical support and direct assistance during response and recovery missions. This is accomplished through the Emergency Support Functions of the NRF. Typical missions/support include: potable water, ice, debris clearance and removal, temporary housing, infrastructure assessment, temporary power and temporary roofing.
Assistance under these two authorities is supplemental to local and State efforts and normally at the request of the State's governor.
