From and after July 1, 1981, any outdoor advertising signs lawfully erected prior to November 6, 1978, which do not conform to the standards adopted by local zoning authorities as authorized by Kan. Stat. Ann. § 68-2234, as amended, may be subject to removal, upon request of the local zoning authority, by the secretary of transportation in the manner provided by the highway advertising control act of 1972. In the event that action by a local zoning authority forces the removal of any such signs for which any person or persons are entitled to just compensation under subsection (g) of Section 131 of Title 23 of the United States Code and not subject to compensation under Kan. Stat. Ann. § 68-2238, the local zoning authority shall be responsible for payment of the non-federal share of such just compensation and for payment of incidental administrative expenses incurred by the secretary of transportation for the removal of such signs.
