Summary
Outdoor advertising signs facing an Interstate highway get extra height and faster message-change allowances under Greensboro's Land Development Ordinance. A billboard within 400 feet of an Interstate right-of-way can rise to 50 feet instead of the standard 40-foot cap, and its digital display can change images every 8 seconds rather than following the citywide hold-time table.
The maximum allowable height of an outdoor advertising sign is 40 feet, provided that the maximum allowable height may be increased to 50 feet if the sign is within 400 feet of the right-of-way of an Interstate Highway... An electronic display sign message may change no more frequently than once every 8 seconds when located within 400 feet of an interstate highway. In all other areas the sign must comply with the electronic message board standards of Table 14-4 (See 30-14-8), based on the zoning district in which the sign is located.
Full Breakdown
4 of the LDO sets the baseline height for an outdoor advertising sign at 40 feet, then carves out an exception: the maximum allowable height may be increased to 50 feet if the sign is within 400 feet of the right-of-way of an Interstate Highway. 5, which keep outdoor advertising signs at least 500 feet from one another and 300 feet from any residential district or religious assembly use. 8(C) states that an electronic display sign message may change no more frequently than once every 8 seconds when located within 400 feet of an interstate highway, compared with the much slower minimum hold times of 1 minute to 6 hours that apply to electronic message boards elsewhere in the city under Table 14-4. 8(D), which requires a Special Use Permit and overnight shutoff for any digital replacement sign within 300 feet of a residential use.
Violations & Fines
A billboard built above 50 feet, or a digital display near an interstate that changes images faster than once every 8 seconds or fails to meet the underlying 400-foot distance test, is cited through the standard LDO process: a Notice of Violation under § 30-5-3.1, then a civil penalty of $50 for a first violation rising to $500 for the fourth and later violations under § 30-5-5.4(A), with a 30-day right to appeal to the Board of Adjustment.
