Part 7 of Article 19 in Chapter 160A details the authority to cities and counties to create community appearance commissions. Section 160A-451 permits a city or county to create an official appearance commission. This commission is required to study the “visual problems” within the local government’s jurisdiction and make plans to carry out programs that will “enhance and improve” the city or county’s “visual quality and aesthetic characteristics.” § 160A-452. In addition to other its powers and duties, the commission may advise the planning agency or governing board regarding ordinances it believes would improve the city or county’s appearance. § 160A-452(6)(c).
