About Coastal Flood Exposure Mapper

The information in this product is based on the Roadmap for Adapting to Coastal Risk approach to assessing coastal hazard risks and vulnerabilities. The Roadmap for Adapting to Coastal Risk was developed by NOAA as an approach to help communities assess coastal hazard risks and vulnerabilities. With this approach, communities looked at how hazards were impacting their people, places, and natural resources and identified planning, policies, and actions to help reduce these impacts. We developed the Coastal Flood Exposure Mapper to help communities kick-start conversations about coastal risks. The mapper enables users to explore maps that show people, places, and natural resources exposed to coastal flood hazards and create a collection of maps to share and communicate about flood exposure.

Disclaimer

The purpose of this mapping application is to provide a preliminary look at exposure to common types of coastal flooding. The viewer is a screening-level tool that uses nationally consistent data sets and analyses and should be used as such. Data and maps provided can be used at several scales to help gauge impacts and prioritize actions, but should be verified with a site visit. The data and maps in this tool illustrate the scale of potential flooding, not the exact location, and do not account for all physical or anthropogenic processes. The data and maps in this tool are provided “as is,” without warranty to their performance, merchantable state, or fitness for any particular purpose. The entire risk associated with the results and performance of these data is assumed by the user. This tool should be used strictly as a planning reference tool and not for navigation, permitting, or other legal purposes.
