Hazard and Flooding Mitigation Funding Assurance Act

This bill guarantees that the federal government will cover at least 75% of eligible costs for hazard and flooding mitigation projects, instead of allowing up to 75%. It directly affects state and local governments applying for federal disaster relief funds under the Stafford Act. Key provisions include changing the funding requirement to a minimum 75% federal share (with a possible 100% maximum) and adding a new requirement to address post-wildfire flooding and debris flow from burned areas. The bill takes effect for assistance provided after its enactment date.
