The Commercial Corridor Design Overlay District was originally adopted in 2002 to enhance the quality and compatibility of development and establish consistent architectural guidelines along the City's primary corridors.

In particular, the overlay is intended to:

• Articulate positive visual experiences in Marietta's downtown area
• Provide for the continued safe and efficient utilization of roads
• Promote pedestrian mobility and safety
• Provide for the preservation of historically significant structures

Two Tiers

The overlay district is divided into two tiers:

• Tier A is centered along Roswell Street between Haynes Street to Cobb Parkway (US Highway 41)
• Tier B centers along sections of Fairground Street, Atlanta Street, Powder Springs Street, and Whitlock Avenue
