Welcome to the Salem Overlay District homepage! Newton County, Georgia hired the Collaborative Firm, LLC in 2012 to design an overlay district for the Salem Road area. An overlay is a kind of zoning that applies in addition to your normal zoning. Municipalities can use overlays to help create quality development by regulating features like architectural details, color palettes, sidewalks, and street furniture to create a more consistent look. Be sure to check the News tab, or see the headlines to the right to get the latest information about the overlay.
