Map Changes 101 - Understanding the Basics
What is a Flood Map
  • Flood hazard maps, also called Flood Insurance Rate Maps (FIRMs), reflect a community’s flood zones, Base Flood Elevations (BFEs), and floodplain boundaries, which collectively are used to determine flood risk. FIRMs are the most commonly distributed NFIP flood maps.
  • Flood Maps help establish flood insurance requirements and rates for the National Flood Insurance Program (NFIP).
  • The Federal Emergency Management Agency (FEMA) works with communities across the nation to identify flood hazards and publish flood maps to help property owners and communities understand the degree of risk in those areas and guide them to mitigation actions.

All too often, people think their property is not at risk because it isn’t in a high-risk flood zone or has never flooded. In fact, approximately 64 percent of households impacted by the hurricanes Harvey, Irma and Maria in 2017 did not have flood insurance.
