This legislation amends the Robert T. Stafford Disaster Relief and Emergency Assistance Act to establish an alternative block grant program for funding public assistance following a major disaster. This program allows states to elect to receive a single block grant, calculated by the Federal Emergency Management Agency (FEMA), in lieu of applying for traditional direct public assistance. FEMA will assess the eligible public assistance costs for an impacted state, including administrative expenses, and reduce the total by the non-Federal share. States can request a single adjustment to the grant amount if it is initially insufficient to complete necessary recovery activities. A crucial aspect is that states receiving a block grant for a specific disaster will not be eligible for other direct public assistance under the Act for that same event. Any funds remaining after the completion of recovery activities can be repurposed by the state for eligible preparedness or mitigation activities . The bill mandates comprehensive reporting from participating states, including initial recovery plans and annual expenditure reports, and requires the Administrator to submit annual reports to Congress on the program's implementation, challenges, and effectiveness.
