NOAA's Coastal Flood Exposure Mapper enables users to visualize anticipated flooding effects along the entire U.S. East Coast and Gulf of Mexico in order to craft better resilience plans. According to the 2010 U.S. Census Bureau population count, 39 percent of the U.S. population lives in counties subject to significant coastal flooding. Charleston, South Carolina, shown here, is an example of one U.S. city with an increased risk of nuisance flooding, according to a 2014 NOAA report.
NOAA's Coastal Flood Exposure Mapper is a free online tool that provides maps, data, and information to assess risks and vulnerabilities related to coastal flooding and hazards. The tool is available for the entire U.S. East Coast and Gulf of Mexico.
With the Coastal Flood Exposure Mapper, you may select a location and a flood scenario of your choosing: Federal Emergency Management Agency flood designations, shallow coastal flooding associated with high tides, or flooding associated with sea level rise or storm surge. Flood maps are then overlaid with any of three exposure maps to show how floodwaters might impact area assets:
All maps can be saved, printed, and shared.
