# Hawaii Flood Hazard Assessment Tool

State of Hawaii, Department of Land and Natural Resources Flood Hazard Assessment Tool Home Loading… FHAT Close Department of Land and Natural Resources Flood Hazard Assessment Tool Terms of Use WELCOME Welcome to the Hawaii Department of Land and Natural Resources Flood Hazard Assessment Tool (FHAT). The FHAT is an informational mapping viewer that displays flood zones. The source of flood zone information contained in the FHAT is FEMA's Digital Flood Insurance Rate Maps (FIRMs). Note: The FHAT does not identify all areas subject to flooding. Individual counties may regulate development in: non-Special Flood Hazard Areas where potential flooding may exist; and/or to a higher flood risk other than identified on the current effective FIRMs. Please contact the appropriate county floodplain manager for additional flood hazard maps and/or permitting requirements.

The ground elevation provided is an approximation using the USGS National Map Elevation Point Query Service, part of the USGS 3DEP program. For the State of Hawaii, this data has not yet been updated similar to much of continental U.S., however it can be used as an order of magnitude when attempting to compare with the Base Flood Elevation (BFE). For more information on the USGS 3DEP Program, visit: https://www.usgs.gov/3d-elevation-program . For specific information on the USGS National Map Elevation Point Query Service, visit: https://apps.nationalmap.gov/epqs . Note this information does NOT replace the need for a survey to determine existing ground elevations. To retrieve an estimated ground elevation based on the USGS National Map Elevation Point Query Service, click the tripod icon below to activate the tool, then click a point of interest on the map to get the estimated elevation.    Click the survey icon and click up to 5 points for estimated ground elevation.
