Federal Emergency Management Agency (FEMA) Hazard Mitigation Assistance [October 24, 2019] [open pdf - 531KB]
From the Introduction: "The majority of funding in the United States for both pre- and post-disaster mitigation comes from the Federal Emergency Management Agency (FEMA), which defines mitigation as 'any sustained action to reduce or eliminate long-term risk to people and property from natural hazards and their effects.' Mitigation actions have a long-term impact, as opposed to actions that are associated with immediate preparedness, response, and recovery activities. Mitigation has been shown to save money. A recent study by the Multihazard Mitigation Council found that society saves $6 for every dollar spent on mitigation funded through major federal mitigation grants. FEMA administers three hazard mitigation grant programs, which it collectively refers to as Hazard Mitigation Assistance (HMA):  the Hazard Mitigation Grant Program (HMGP);  the Pre-Disaster Mitigation (PDM) Grant Program; and  the Flood Mitigation Assistance (FMA) Grant Program."
