To do so, you will need GIS or mapping software that can read data in shapefile format.įEMA also offers a download of a KMZ (keyhole markup file zipped) file, which overlays the data in Google Earth™. In partnership with water management districts, communities and the State. This data can be used in most GIS applications to perform spatial analyses and for integration into custom maps and reports. SFHAs are labeled as Zone A, Zone AO, Zone. The 1-percent annual chance flood is also referred to as the base flood or 100-year flood. As outlined in 44 CFR 65.10, to achieve accreditation, a levee system must meet certain requirements to demonstrate that it is constructed high enough and strong enough to reduce the. SFHA are defined as the area that will be inundated by the flood event having a 1-percent chance of being equaled or exceeded in any given year. Zone D is the resulting designation on the flood map, to indicate that while flood risk remains, the probability of that flood risk has not been quantified. Base flood elevations derived from detailed analyses are shown at selected intervals within these zones. Flood hazard areas identified on the Flood Insurance Rate Map are identified as a Special Flood Hazard Area (SFHA). These areas have a 26 chance of flooding over the life of a 30year mortgage. Using the “Search All Products” on the MSC, you can download the NFHL data for a County or State in a GIS file format. Areas with a 1 annual chance of shallow flooding, usually in the form of a pond, with an average depth ranging from 1 to 3 feet. You can also use the address search on the FEMA Flood Map Service Center (MSC) to view the NFHL data or download a FIRMette. During the span of a 30-year mortgage, these areas. An area having special flood, mudflow or flood-related erosion hazards and shown on a Flood Hazard Boundary Map (FHBM) or a Flood Insurance Rate Map (FIRM) Zone A, AO, A1-A30, AE, A99, AH, AR, AR/A, AR/AE, AR/AH, AR/AO, AR/A1-A30, V1-V30, VE or V.

This 1 chance flood is also known as the base flood or 100-year flood. What are Flood Zone Designations Flood Zone Designations are geographic areas as having different levels of flood risk. For more information on available services, go to the NFHL GIS Services User Guide. Areas with a 1 chance or higher of flooding are considered high risk. The FEMA Flood Insurance Rate Maps (FIRM) for Horry County have been scanned and converted to DjVu format for viewing.

Technical GIS users can also utilize a series of dedicated GIS web services that allow the NFHL database to be incorporated into websites and GIS applications.

In the NFHL Viewer, you can use the address search or map navigation to locate an area of interest and the NFHL Print Tool to download and print a full Flood Insurance Rate Map (FIRM) or FIRMette (a smaller, printable version of a FIRM) where modernized data exists. Enter your property address in the field in the upper-right of the flood risk map to see if your property is in a flood risk area. Or you you may view, download, and print current local digital effective flood hazard data in an ArcGIS map.
