Forsyth County commissioners on Thursday will consider the addition of an overlay district along Buford Highway. The proposal would set aesthetic requirements for new development on the Ga. 20 corridor from the Cumming city limits to the Forsyth-Gwinnett County line. An overlay district is used to establish alternative land development requirements within a specific area of your community that requires special attention, such as an environmentally sensitive area or rapidly developing strip corridor, according to the Georgia Department of Community Affairs.
