The Roswell City Council is moving to amend city codes concerning historic properties.

As required by the state, the council voted to initiate text amendments to the Unified Development Code to establish how landmarks are designated, and criteria for how historic districts are expanded. The Roswell Historic Preservation Commission is to consider the measures on Nov. 14, and the Planning Commission, on Nov. 20, before they return to the council for a first reading.

For a landmark designation or historic district boundary change, the Historic Preservation Commission would investigate and report “on the historic, cultural, architecture or esthetic significance” of properties to an office of the Georgia Department of Natural Resources.

A public hearing would be scheduled, and the owners and occupants affected by the designation or boundary change, notified. If the changes are approved, residents would be advised within 30 days how to obtain a certificate of appropriateness prior to making material changes to a historic property’s appearance.
