The Cobb County Board of Commissioners approved on March 12 a $171,938 contract with W. E. Contracting Company Inc. to repair stormwater drainage issues at Fullers Park.
The damage resulted from athletic field renovations at Fullers Park, 3499 Robinson Road, Marietta that is funded by the 2011 PARKS Special Purpose Local Option Sales Tax program.
Many of these upgrades were completed earlier in the program, resulting in increased sheet flow during rain events, said PARKS Director Jimmy Gisi in a March 12 memo.
More recently, the failure of a stormwater conveyance system was discovered, causing a serious surface erosion problem which must be corrected, he added.
If allowed to continue, the erosion will threaten neighboring properties, Gisi said.
Cobb County Water System employees have helped PARKS explore the problem, including using their remote-controlled camera system to reveal deterioration of an older, corrugated metal pipe which contributes to the problem.
Staff and an outside engineering firm have determined the requirements and developed a scope of work to replace the reinforced concrete pipe and other concrete stormwater management structures to solve the surface erosion issues.
The deteriorating corrugated metal pipe is a candidate for the CIPP (Cured-In Place Pipe) trenchless pipe rehabilitation method, Gisi said.
Performing this repair now will avoid much costlier full-scale pipe replacement in the future, he added.
