Volusia County, FL national flood hazard layer generated from FEMA data on 10/1/2024.

Four panels were revised Aug. 7, 2018 and have been included in the product. Four LOMR areas were included in Jan. 2020 and reflect changes ranging from Aug. 28, 2018 through Jan. 10, 2020.These files are digital copies of the flood risk maps for Volusia county in PDF file format.

To view the most up to date information, visit FEMA’s NFHL Viewer. The most recent official shapefiles can be downloaded from the FEMA Flood Map Service Center.A FIRM (also referred to as a flood map) is the official map that shows Special Flood Hazard Areas (SFHA) and the risk premium zones applicable to a community. Risk zones indicated on a FIRM provide a basis for establishing flood insurance coverage premium rates offered through the National Flood Insurance Program (NFIP).This dataset enables a visualization of the floodplain and floodway extents. Due to the nature of this data, often times ESRI generated base maps and flood data can potentially be misaligned, therefore actual flood extents may be misrepresented. This product is not intended to be used for regulatory purposes and should only be used as a planning and visualization tool.
