Coastal Flood Exposure Mapper

Access maps showing where people, places, and natural resources are exposed to coastal flooding. Local leaders can use these maps to support a community-based approach for assessing vulnerabilities to coastal hazards. Users simply select their geography to generate a collection of maps for download or sharing online.
