Description

Federal Emergency Management Agency (FEMA) National Flood Hazard Layer (NFHL) Viewer is an interactive web application that provides detailed, up-to-date flood hazard information across the United States. It allows users to visualize and analyze flood risk data by overlaying FEMA’s official flood maps on a dynamic Geographic Information System based interface. The application includes a searchable map where users can enter an address or location to view flood zones, floodways, and base flood elevations. The map features various tools such as a legend, layer list, and basemap options, enabling users to customize their view and better understand local flood risks. Users can click on specific areas to access detailed flood data and map panel information, which is crucial for floodplain management, insurance decisions, and emergency planning. The NFHL Viewer serves as an essential resource for property owners, planners, engineers, and emergency managers to make informed decisions about development, safety, and flood insurance requirements.
