A Norcross firm that has done work for Flowery Branch, including a downtown transportation study in 2010, is gearing up for a $125,000 study of Gainesville’s traffic needs. Pond & Co. of Norcross got the green light last week when the Hall County Board of Commissioners approved a contract with the firm. The city will bear $25,000 of the cost, with the Federal Highway Administration paying $100,000.
