During a work session Monday in Milton, Fulton County Commissioner Lynne Riley told a crowd of about 60 people that some businesses on Ga. 9 are eligible for sewer service, but there are no plans to expand it beyond that area. She also said there is no contradiction between the map of the county's sewer service and its policy on not allowing sewer from one river basin to flow into another basin. Ga. 9 runs along the eastern side of the city. The perception that there was a discrepancy had fueled concern among many residents that once sewer crossed from the Big Creek basin to the Etowah River basin, the flood gates would open, and sewer would expand throughout the city.
