The bill aims to establish a pilot program to provide grants to local governments for urban flooding mapping and risk assessment. The grants seek to enhance the production of maps related to urban flooding and provide risk assessment information to homeowners and local governments. The Administrator will select grant recipients based on the priority of achieving program objectives. The program will prioritize vulnerable areas, locations with national security interests, and areas with uneven flood mitigation capabilities. Grantees are obliged to complete the program activities within 18 months and report to FEMA, with the agency also required to submit reports to Congress. The bill emphasizes the importance of structural-based flood mitigation and construction for urban flooding. It authorizes specific funding for fiscal years 2027 and 2028.
