In granting any permit under or variance from any airport zoning regulation adopted under the Airport Zoning Act, the administrative agency or board of adjustment may, if it deems it advisable to effectuate the purposes of the act and reasonable in the circumstances, so condition such permit or variance as to require the owner of the structure or tree in question to permit the political subdivision, at its own expense, to install, operate, and maintain thereon such markers and lights as may be necessary to indicate to flyers the presence of an airport hazard.
