Home » Coastal Flood Exposure Mapper
The Coastal Flood Exposure Mapper supports users undertaking a community-based approach to assessing coastal hazard risks and vulnerabilities by providing maps that show people, places, and natural resources exposed to coastal flooding. This spatial visualization tool shows maps of people, places, and natural resources exposed to coastal flood hazards including FEMA flood zones, shallow coastal flooding, sea level rise, storm surge. Features allow users to select a location and explore maps, create collections of maps to download or share online, and provide guidance for using these maps to engage community members in conversations about flood impacts. Maps are available for the East Coast, Gulf of Mexico, and the US islands and territories in the Pacific and Caribbean.
