Traffic congestion on Spout Springs Road loomed over the approval of a 10-acre expansion of a 352-unit apartment complex in South Hall on Monday. Morningstar Investment Group has taken over the 3-year-old project on Spout Springs Road in unincorporated Hall County near Flowery Branch. The project was first approved by the Hall County Board of Commissioners in 2014. On Monday, the Hall County Planning Commission approved Morningstar’s request to rezone two lots near the original project to add another 10 acres to the complex. The request wouldn’t add additional apartments to the complex, and the addition of the 10 acres must be approved by the Hall County Board of Commissioners in November.
