A. Reasonableness. All airport zoning regulations adopted under this article shall be reasonable; none shall impose any requirement or restriction unless it is reasonably necessary to effectuate the purpose of this article. In determining what regulations it may adopt, Lawrence Township shall consider, among other factors, the character of the flying operations expected to be conducted at the airport, the nature of the terrain within the airport hazard area, the character of the neighborhood and the uses to which the property to be zoned is put and adaptable.
B. Use restrictions. Notwithstanding any other provisions of this article, no use may be made of land or water within any zone established by this article in such a manner as to create electrical interference with navigational signals or radio communication between the airport and aircraft, make it difficult for pilots to distinguish between airport lights and others, result in glare in the eyes of pilots using the airport, impair visibility in the vicinity of the airport, create bird strike hazards or otherwise in any way endanger or interfere with the landing, takeoff or maneuvering of aircraft intending to use the airport.
C. Nonconforming uses.
(1) Regulations not retroactive. The regulations prescribed by this article shall not be construed to require the removal, lowering or other change or alteration of any structure or trees not conforming to the regulations as of the effective date of this article, or otherwise interfere with the continuance of any nonconforming use, except as provided in §
125-55 (relating to permits and variances). Nothing contained herein shall require any change in the construction, alteration or intended use of any structure, the construction or alteration of which was begun prior to the effective date of this article, and is diligently executed.
(2) Marking and lighting. Notwithstanding the preceding provision of this section, the owner of any existing nonconforming structure or tree is hereby required to permit the installation, operation and maintenance thereon or nearby of such markers and lights as shall be deemed necessary by the Clearfield Borough-Lawrence Township Airport Authority to indicate to the operators of aircraft in the vicinity of the airport the presence of such airport obstruction. Such markers and lights shall be installed, operated and maintained as required by federal and state statutes and regulations, and, in the absence thereof, at the expense of the Clearfield Borough-Lawrence Township Airport Authority.
