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.

How-To

How do I use the site?

Explore the six links along the left margin—Sea Level Rise, Local Scenarios, Mapping Confidence, Marsh Migration, Vulnerability, and High Tide Flooding—to view visualizations under each category.
Use the slider bar (on most tabs) to examine the impacts of different sea level rise scenarios.
Read the overview text directly below the legend to learn about individual impacts.
Click the ? in the lower right corner for additional information.

What can I do with these data?

Take a look at coastal areas likely to be inundated at high tide after various amounts of sea level rise.
Visualize the impacts of sea level rise and prioritize actions for different scenarios.
