Flood Mapping Modernization and Homeowner Empowerment Pilot Program Act of 2024

This bill creates a FEMA pilot program to provide grants to 12 U.S. cities (with populations over 50,000) for developing and sharing improved flood risk maps focused on urban flooding. The maps will show specific building-level flood risks from heavy rain and climate change, and must be made publicly available online for homeowners and businesses to help them reduce flood damage. Participating cities must complete the mapping within 18 months and report results, with grants covering up to 75% of costs. The program aims to empower communities with clearer flood risk data for better preparedness and mitigation planning.
