Sea Level Rise - Map Viewer

Sea Level Rise and Coastal Flooding Impacts

Dataset Tabs Default Display

General

NOAA's Sea Level Rise map viewer gives users a way to visualize community-level impacts from coastal flooding or sea level rise (up to 10 feet above average high tides). Photo simulations of how future flooding might impact local landmarks are also provided, as well as data related to water depth, connectivity, flood frequency, socio-economic vulnerability, wetland loss and migration, and mapping confidence. The viewer shows areas along the contiguous United States coast, except for the Great Lakes. 

Where do these maps come from?

The maps are produced using detailed elevation maps with local and regional tidal variability.
