Hall County and Gainesville approved an agreement Monday to provide sewer service to the Ga. 365 corridor after the county spent nearly a year changing its mind on how to provide service to that area. The Hall County Board of Commissioners began considering options for sewer service at the 518-acre Gateway Industrial Centre under development on Ga. 365 in North Hall and the corridor area nearly a year ago. The county agreed to provide sewer to the industrial park.
