An agency of the U.S. Department of Homeland Security that provides a single point of accountability for all federal emergency preparedness, mitigation, and response activities. FEMA's primary purpose is to coordinate the response to a disaster that overwhelms the resources of state and local governments. It works closely with these governmental bodies by funding emergency programs and offering technical guidance and training. In addition, FEMA administers the National Flood Insurance Program (NFIP) and advises communities on building codes, emergency response, and floodplain management.
