A South Hall Republican Club meeting on Monday ended with a grilling about potential tax and sewer rate increases for two members of the Hall County Board of Commissioners. Chairman Richard Higgins and Commissioner Kathy Cooper spoke to a packed room at the South Hall GOP’s meeting at the Spout Springs branch of the Hall County Library in Flowery Branch. The two gave a review of the county’s 2016 operations and discussed its 2017 developments, including Georgia Department of Transportation’s multiyear, $92 million widening of Spout Springs Road, but the audience of more than 50 people became most animated about coming changes to county sewer rates and the possibility of a property tax increase.
