Mableton, GA
Water damage in Mableton, GA: a new city on Cobb Water
Mableton became a city after a November 2022 vote, with the Chattahoochee River along its southeast edge and Nickajack Creek, which once turned grist, saw and woolen mills, running near its northern end. In September 2009 Nickajack crested at 19.85 feet against a flood stage of 10, which is why the flooded basement page gets read here. Call (678) 737-4866 and give the street address.
