Summary
Marietta strictly limits new billboards to the Interstate 75 corridor, and digital billboards face an added layer of rules: static messages only, minimum 15-inch letter height, a brightness cap tied to distance, and a 5,000-foot buffer from any other digital billboard on the same side of the road.
1.The erection and maintenance of new billboards should be strictly limited in areas adjacent to Interstate 75, and are prohibited in all other areas in order to protect the public investment in such roadways, preserve the City's scenic beauty and distinctiveness, and promote the general health and welfare of the public. ... 14.A digital billboard shall:a.Contain static messages only, and shall not have movement, scrolling, fading or flashing on any part of the sign structure, design, or pictorial segment of the sign, nor shall such sign have varying light intensity during the display of any single message.b.Every line of copy and graphics in a digital display must be at least 15 inches in height. If there is insufficient room for copy and graphics of this size in the maximum allowable sign area, then no digital display is allowed. ... f.No digital billboard shall be located within 5,000 feet of another digital billboard on the same side of the road.

Full Breakdown
04(G)(13)-(14) allows digital billboards only as part of a policy limiting new billboard construction to areas adjacent to Interstate 75 while prohibiting them everywhere else in the city, in a deliberate trade of quantity for technology: an existing static panel may be converted to digital only if at least 4 existing billboard panels are removed entirely and their structures taken down to the foundation. A converted or new digital billboard must display static messages only, with no movement, scrolling, fading or flashing and no varying light intensity within a single message, and every line of copy and graphics must be at least 15 inches tall or no digital display is permitted at all.
20 foot-candles above ambient light, measured at a distance that scales with sign size: 150 feet for signs under 300 square feet, 200 feet for 301-400 square feet, and 250 feet for 401-672 square feet, with an independent contractor required to certify compliance annually. S. Highway 41. The sign owner must give the City a 24-hour emergency contact, and if more than half the display's lights malfunction, the owner has 60 days to repair the sign or it must come down; a City finding of excess brightness gives the owner 24 hours to bring it into compliance.
Violations & Fines
Operating a digital billboard above the 0.20 foot-candle brightness cap, after City staff request corrective certification, gives the owner just 24 hours to fix the intensity before it is out of compliance with § 714.04(G)(14). Letting more than 50% of a sign's display lights fail without repairing them within 60 days requires the sign to be removed, and converting a static billboard to digital without first removing the required 4 existing panels voids the permit basis for the conversion entirely.
