Flood mapping tool unveiled Wednesday in Austell

The U.S. Geological Survey will showcase a new online flood mapping tool on Wednesday that will help emergency managers in the flood-prone Sweetwater Creek area in Cobb County.

The flood inundation map is the first of its kind created for a major urban area in the southeastern United States. The map will help identify where the potential threat of floodwaters is greatest and allow for quick decisions to be made on area evacuations.

Sweetwater Creek accounted for unprecedented flooding and flood damage during the historic floods of 2009.

The unveiling begins at 10 a.m. at Legion Park, 5514 Austell Powder Springs Road in Austell.
