FEMA reviews each project for quality assurance, insurance, hazard mitigation and environmental and historic compliance, then obligates the federal share to the recipient (your state, tribe or territory), which passes it to you. For permanent work projects over $1 million that won’t need money for more than 180 days, FEMA obligates on your project schedule instead of all at once.
Your project completion schedule (needed for strategic funds management on permanent work projects over $1 million), and the recipient’s notice that funds are available.
Obligation is not payment. The money sits with the recipient, which pays you under its own rules and timelines. Ask early how your recipient handles reimbursement requests and advances.
