Sea Level Rise and Coastal Flooding Impacts Viewer
Being able to visualize potential impacts from sea level rise is a powerful teaching and planning tool. The Sea Level Rise and Coastal Flooding Impacts Viewer, developed by the NOAA Office for Coastal Management, offers access to data and information about the risks of sea level rise, storm surge, and flooding along the coastal United States. The web-based map allows community planners, city officials, and coastal residents the opportunity to identify flood-prone locations in their area.
The tool offers hard-to-find data and information regarding the flood risks due to various possible scenarios of sea level rise. Community planners can assess what infrastructure is vulnerable under these conditions, and the tool enables business- and homeowners along the coasts to make decisions regarding their livelihoods and see how rising sea levels may affect them in the future.
A slider bar is used to show how various levels of sea level rise will impact coastal communities. It is distinct from viewers provided by the Federal Emergency Management Agency (FEMA) because, unlike the FEMA tools that indicate what areas have flooded in the past, the Sea Level Rise and Coastal Flooding Impacts Viewer shows potential future inundation from daily tides along U.S. coasts if global sea level rose up to six feet.
Additional coastal counties will be added in the near future. Maps are not currently available for Alaska.
