Sea Level Rise - Map Viewer

Sea Level Rise and Coastal Flooding Impacts

Dataset Tabs Default Display

General

This map viewer illustrates the scale of potential coastal flooding after varying amounts of sea level rise. Users can simulate inundation associated with one to six feet of sea level rise at various scales along the contiguous United States coast, except for the Great Lakes. 

The maps are produced using detailed elevation maps with local and regional tidal variability. They show the extent of inundation likely at high tide after various amounts of sea level rise.
