Revitalizing Flowery Branch’s Old Town area is key to the future of the South Hall city, according to residents who attended a meeting Tuesday about the city’s comprehensive plan. Many of the nearly two dozen people at the meeting at the Flowery Branch Depot said freeing up retail space in Old Town would be a plus. City Planner John McHenry said building managers there also would like to attract retail to bring shoppers to the Main Street area.
