The maximum amount of HMGP assistance available is calculated using a sliding scale formula based on a percentage of the estimated total federal assistance under the Stafford Act, excluding administrative costs for each major disaster declaration.
Applicants with a FEMA-approved state or tribal mitigation plan may receive:
- Up to 15% of the first $2 billion of the estimated aggregate amount of disaster assistance.
- Up to 10% for the next portion of the estimated aggregate amount more than $2 billion and up to $10 billion.
- Up to 7.5% for the next portion of the estimated aggregate amount more than $10 billion and up to $35.333 billion.
Applicants with a FEMA-approved state or tribal enhanced mitigation plan are eligible for HMGP assistance not to exceed 20% of the estimated total federal assistance under the Stafford Act, up to $35.333 billion of such assistance, excluding administrative costs authorized for the disaster. Figure 8 highlights how the HMGP funding ceiling is generally calculated.
