(a) Any person desiring to erect any structure, or increase the height of any structure or permit the growth of any tree, or otherwise use his property in a manner contrary to the airport zoning regulations adopted under this chapter, may apply to the Zoning Administrator for a variance from the zoning regulations in question. Applications for approvals granted pursuant to this Chapter shall be made in accordance with the requirements of Chapter 18.10, Level V. Such variances shall be allowed where a literal application or enforcement of the regulations would result in practical difficulty or unnecessary hardship and the relief granted would not be contrary to the public interest, but would do substantial justice and be in accordance with the spirit of the regulations and this chapter; provided, that any variance may be allowed subject to any reasonable conditions that the Zoning Administrator may deem necessary to effectuate the purposes of this chapter.
(b) In granting any permit or variance under this chapter, the Zoning Administrator may, if he deems such action advisable to effectuate the purposes of this chapter and it is reasonable in the circumstances, condition such permit or variance so as to require the owner of the structure or tree in question to permit the County, at its own expenses to install, operate and maintain thereon such markers and lights as may be necessary to indicate to flyers the presence of an airport hazard.
