An apartment complex designed for seniors is planned near the Ga. 400 corridor. “There’s absolutely a need for more elderly housing in Dawson County,” said developer Kevin Buckner. The county commissioners approved Buckner’s request Thursday to rezone nearly 10 acres at 7142 Ga. 53 East, across from Tractor Supply Co., where Farmington Forest, a 55-and-older complex, will be built.
