23 CFR 750.705 – Effective control
In order to provide effective control of outdoor advertising, the State must:
(a) Prohibit the erection of new signs other than those which fall under § 750.704(a)(1) through (6);
(b) Assure that signs erected under § 750.704(a)(4) and (5) comply, at a minimum, with size, lighting, and spacing criteria contained in the agreement between the Secretary and the State;
(c) Assure that signs erected under § 750.704(a)(1) comply with the national standards contained in subpart B, part 750, chapter I, 23 CFR;
(d) Remove illegal signs expeditiously;
(e) Remove nonconforming signs with just compensation within the time period set by 23 U.S.C. § 131 (subpart D, part 750, chapter I, 23 CFR, sets forth policies for the acquisition and compensation for such signs);
(f) Assure that signs erected under § 750.704(a)(6) comply with § 750.710, Landmark Signs, if landmark signs are allowed;
(g) Establish criteria for determining which signs have been erected with the purpose of their message being read from the main-traveled way of an Interstate or primary highway, except where State law makes such criteria unnecessary. Where a sign is erected with the purpose of its message being read from two or more highways, one or more of which is a controlled highway, the more stringent of applicable control requirements will apply;
(h) Develop laws, regulations, and procedures to accomplish the requirements of this subpart;
(i) Establish enforcement procedures sufficient to discover illegally erected or maintained signs shortly after such occurrence and cause their prompt removal; and
(j) Submit regulations and enforcement procedures to FHWA for approval.
