(3) Landmark Signs
Signs lawfully in existence on October 22, 1965, determined by the Commissioner, subject to the concurrence of the Secretary of Transportation of the United States, to be landmark signs, including signs on farm structures, or natural surfaces, of historic or artistic significance, the preservation of which would be consistent with the purposes of this section, are not required to be removed. Landmark signs are exempt from permit and fee requirements.
Explanatory Note:
Reasonable maintenance, repair, and restoration of a landmark sign is permitted. Substantial change in the size, lighting, or message content will terminate its exempt status.
