This link goes directly to the FEMA Map Service: Click Here
The site can be a little slow aand a little frustrating-But it is "The" source for flood info and maps.
You can buy maps for a nominal fee (Both downloadable and print) of specific areas on interest. I have almost all the flood maps on file and use them daily!
Another good site is the North Carolina Flood Mapping site: Click Here
. It too is slow and can be frustrating-But invaluable info.
