To bring the Seven Oaks subdivision dam into compliance with EPD regulations, Johns Creek recently approved a $1,115,881 contract with Summit Development & Construction, LLC and a $137,000 construction, engineering, inspection contract with Dewberry for the dam repair.
When the dam was re-classified as a Category I dam in 2018, an inspection revealed deficiencies including trees growing on the dam and the slopes, erosion of ground cover, non-pressure sealed drainage pipes, roadway drainage connected to the lake drain, and lack of secondary overflow for the lake.
The city received final approvals and a permit for construction of the engineered repairs on May 3. At the request of the Seven Oaks Homeowners Association, the city postponed bidding the construction project until August so the lake could be used for irrigation during the summer months.
Fulton County is contributing $200,000 toward the repairs. The recommended construction costs require $123,181 in additional funds to be set aside from the city’s stormwater repairs and maintenance and $656,263, or 40% of construction cost, from the Seven Oaks HOA.
