About FEMA Maps

| .... |
One of FEMA's jobs is to perform flood studies, and data generated by these studies comes in two parts: The Flood Insurance Rate Maps (FIRM) and Flood insurance Studies (FIS). The output from the FIS shows the elevations at which bodies of water are predicted to rise to in any given storm event. The FIRM's show these elevations as certain boundaries, known as Special Flood Hazard Areas (SFHA).
These FIRM's are the basis for floodplain management, mitigation and insurance activities of the National Flood Insurance Program (NFIP). Therefore the SFHA's shown on the FIRM's are the starting point for the flood insurance rates that NFIP offers.
With the revision of the FIRM's in 2010, GIS shapefiles of the data are now available to the public. This means that communities can overlay FEMA's flood data with their own land base (such as buildings, roads and parcels). Overlaying these two data sets provides an easier way to locate SFHA's for a given property, and also to view the flood data on a larger scale. However, it's important to note that the presentation of any FEMA data (such as the GIS flood plain data) anywhere other than on the FIRM's are for reference purposes only.
