Visit North Carolina’s Floodplain Mapping Information System website at
You can view, print or download digital versions of the Digital Flood Insurance Rate Maps (DFIRMs) produced by the North Carolina Floodplain Mapping Program
by clicking on “Digital Flood Maps.”
Digital flood maps are composites of base data, topographic data and flood layers which can be overlain with local parcel information or other data to more easily determine if a house or other property is or will be located in a Special Flood Hazard Area or floodway.
At the Gaston County Interactive GIS website, you can select optional map layers on the right side menu. Select "Natural" to choose overlays for "Special Flood Hazard Areas", "Floodway", and "Creeks, Streams & Rivers."
