The Hall County Board of Commissioners will vote tonight on several rezoning requests that, if approved, would expand business in South Hall and add a new subdivision off Buffington Farm Road. Meanwhile, a proposed 50-lot subdivision on Conner Road in South Hall has been tabled at the request of the developer. Planning officials want to require the developer to pay for all road widening and right of way access costs to improve Conner Road, which residents said cannot accommodate two-way traffic.
