Cobb County officials are continuing their study of the Sweetwater Creek Basin in hopes of averting future flooding, particularly in the Austell and Powder Springs areas that were overcome by the September 2009 floods from the creek’s overflow.
Costing $150,000, the second phase of the Sweetwater Creek Basin Flood Risk Management Study and Watershed Management Plan will evaluate six options defined in the $50,000 first phase of the study.
Those options will include floodplain purchase, provision of additional retention capacity, channel modifications and flow diversion, according to Cobb County Water System Director Stephen D. McCullers.
Including this $200,000, the overall cost of the study is expected to be $2.4 million with the U.S. Corps of Engineers paying half and the county and possibly Austell, Powder Springs and the state paying the rest.
In March, the Cobb County Board of Commissioners approved an agreement with the U.S. Corps of Engineers to develop this study of flooding in the Sweetwater Creek Basin.
