Coastal Flood Risk

Our nation’s coasts are special places and home to some of our most vital resources. The growing coastal population leads to increased coastal development, which places greater numbers of structures at risk for damage from coastal hazards. 

Coastal hazards like storm surge, hurricane force winds, and flooding place this population at risk. When storms impact the coast, communities can face serious threats to human safety, extensive damage to infrastructure and the built environment, and economic disaster.

Achieving Coastal Resilience

To help these communities understand and reduce their flood risk, FEMA has initiated coastal flood risk studies for 100 percent of the populated coastline.

Through our Risk Mapping, Assessment and Planning (Risk MAP) effort, we're updating the nation’s coastal Flood Insurance Studies (FIS) and Flood Maps, where appropriate, and publishing new flood maps in densely populated areas that were not previously mapped.

FEMA is working with local community officials to produce additional data and hazard mitigation tools to enable more strategic emergency preparedness and mitigation planning in coastal communities.

Coastal Flood Maps

There are two primary flood hazard zones within a coastal special flood hazard area. Learn how coastal hazards are mapped.

Coastal Flood Risk Studies

Updating coastal maps begins with a holistic study during which FEMA meets with stakeholders to share data and identify the best path forward.
