Johns Creek, homeowners face $1M tab to repair Seven Oaks dam

The Johns Creek City Council has approved a $184,447 engineering task order to start the process for bringing the Seven Oaks Lake dam up to state standards. Repairs may cost the city and Seven Oaks Homeowners Association an estimated $1 million, city staff said.

Dewberry, the city’s engineering consultant, will conduct a survey, do geotechnical engineering, prepare an emergency action plan and an operation and maintenance manual, and handle design, permitting, inspections and public outreach, according to a staff report to the council.

The Georgia Department of Natural Resources Environmental Protection Division last year reclassified the dam from Class II to a Class I structure that must meet certain regulatory requirements. Dewberry was hired to visually inspect the dam.

The consultant identified trees growing on slopes, erosion and loss of ground cover, an inlet in disrepair and other deficiencies. “In order to meet the EPD timeline to bring the Seven Oaks dam into compliance, engineered drawings must be prepared this summer,” staff said.

“Staff is also coordinating with the Seven Oaks HOA in order to negotiate an appropriate cost-sharing of the required improvements/repairs to the dam.”
