This web tool visualize present-day storm surge levels and future sea level rise. The data and maps illustrate the potential scale of inundation. The tool has applications for preparedness and prevention in risk management and adaption to climate change. You can get statistics on buildings, area and roads affected by coastal flooding in your community, and download inundation layers for custom GIS applications. The numbers for future sea-level rise take into account vertical land motion. 

For coastal planning, this web tool can help identify areas at risk of inundation, it may not be appropriate for site-specific decision making. In some cases, an onsite visit to verify information in the field is advisable.
