FEMA pilot program would fund urban flood mapping in up to 12 cities

What does this do?

This bill directs FEMA to run a pilot program that funds cities and towns to create detailed flood maps focused on urban flooding, where heavy rain overwhelms storm drains and floods streets, basements, and buildings. Participating communities must make the maps available to the public through a website and complete the work within 18 months. FEMA would then report results to Congress to inform possible wider use of the methods.

Who does it affect?

Homeowners, renters, and business owners in participating cities would gain access to more detailed information about their personal flood risk. Local governments and stormwater agencies in cities with populations above 50,000 could apply for the grants.

Why does it matter?

Current official flood maps often miss urban flooding, which means people may not have accurate information about the flood risk to their specific home or building. This program would test whether newer mapping technology can fill that gap.

What does it cost, and who pays?

• $2M in 2027, $5M in 2028
• Grants cover up to 75% of costs
• Up to 12 communities eligible
