Full Breakdown
Section 25.6.1 of the Boone County Zoning Ordinance confines billboards to the General Commercial (C-G), Light Industrial (M-L) and General Industrial (M-G) districts and their planned counterparts, and only within 100 feet of the U.S. 63 or I-70 right-of-way. Maximum sign area is 288 square feet, one billboard per parcel, and 25.6.1.12 states flatly that 'Billboards shall not be illuminated': a total ban that rules out digital, electronic-message or backlit billboard faces countywide, unlike ordinary signs, which the code allows to use backlighting or floodlighting under Section 25.5.1.
Violations & Fines
Violating any zoning provision, including the billboard illumination ban, is a misdemeanor under Section 18 of the Boone County Zoning Ordinance; the county can also require removal of a nonconforming billboard.
