Definitions. The following words and phrases when used in this section shall have the meaning given to them in this section unless the context clearly indicates otherwise.
The highest point of an airport's usable landing area measured in feet above sea level. The airport elevation of the Zelienople Airport is 898 feet.
Any structure or object, natural or man-made, or use of land which obstructs the airspace required for flight or aircraft in landing or taking off at an airport or is otherwise hazardous as defined in 14 CFR Part 77 and 74 Pa.C.S.A. § 5102.
Any area of land or water upon which an airport hazard might be established if not prevented as provided for in this section and the Act 164 of 1984 (Pennsylvania Laws Relating to Aviation).[1]
An imaginary surface longitudinally centered on the extended runway center line and extending outward and upward from each end of the primary surface. An approach surface is applied to each end of the runway based on the planned approach. The inner edge of the approach surface is the same width as the primary surface and expands uniformly depending on the planned approach. The approach surface zone, as shown on Figure 1,[2] is derived from the approach surface.
An imaginary surface extending outward and upward from the periphery of the horizontal surface at a slope of 20 feet horizontally to one foot vertically for a horizontal distance of 4,000 feet. The conical surface zone, as shown on Figure 1,[3] is based on the conical surface.
Pennsylvania Department of Transportation.
Federal Aviation Administration of the United States Department of Transportation.
For the purpose of determining the height limits in all zones set forth in this section, the datum shall be mean sea level elevation unless otherwise specified.
An imaginary plane 150 feet above the established airport elevation that is constructed by swinging arcs of various radii from the center of the end of the primary surface and then connecting the adjacent arc by tangent lines. The radius of each arc is based on the planned approach. The horizontal surface zone, as shown on Figure 1,[4] is derived from the horizontal surface.
A runway that is constructed for and intended to be used by propeller-driven aircraft of greater than 12,500 pounds maximum gross weight and jet-powered aircraft.
A runway having an existing instrument approach procedure utilizing air navigation facilities with only horizontal guidance, or area type navigation equipment, for which a straight-in, non-precision-instrument approach procedure has been approved or planned.
Any preexisting structure, object of natural growth, or use of land which is inconsistent with the provisions of this section or an amendment thereto.
Any structure, growth, or other object, including a mobile object, which exceeds a limiting height set forth by this section.
A runway having an existing instrument approach procedure utilizing an Instrument Landing System (ILS) or a Precisions Approach Radar (PAR). It also means a runway for which a precision-approach system is planned and is so indicated on an approved airport layout plan or any other planning document.
An imaginary surface longitudinally centered on the runway, extending 200 feet beyond the end of paved runways or ending at each end of turf runways. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway center line. The primary surface zone, as shown on Figure 1,[5] is derived from the primary surface.
A defined area of an airport prepared for landing and takeoff of aircraft along its length.
An object, including a mobile object, constructed or installed by man, including, but without limitation, buildings, towers, cranes, smokestacks, earth formation and overhead transmission lines.
An imaginary surface that extends outward and upward from the edge of the primary surface to the horizontal surface at a slope of seven feet horizontally to one foot vertically. The transitional surface zone, as shown on Figure 1,[6] is derived from the transitional surface.
Any object of natural growth.
A runway that is constructed for and intended to be used by propeller-driven aircraft of 12,500 pounds maximum gross weight or less.
A runway intended solely for the operation of aircraft using visual approach procedures.

D.
Establishment of airport zones. There are hereby created and established certain zones within the Airport Overlay District, as depicted on Figure 1[7] and illustrated on the Zelienople Airport Surface Area Map,[8] which are hereby adopted as part of this section, which include:
E.
Permit applications.
(1)
As regulated by Act 164 and defined by 14 Code of Federal Regulations Part 77.13(a) (as amended or replaced), any person who plans to erect a new structure, to add to an existing structure, or to erect and maintain any object (natural or man-made), in the vicinity of the Zelienople Airport shall first notify the Department's Bureau of Aviation (BOA) by submitting PennDOT Form AV-57 to obtain an obstruction review of the proposal at least 30 days prior to commencement thereof. The Department's BOA response must be included with the Township's zoning permit application for it to be considered complete. If the Department's BOA returns a determination of no penetration of airspace, the permit request should be considered in compliance with the intent of this section. If the Department's BOA returns a determination of a penetration of airspace, the zoning permit shall be denied, and the project sponsor may seek a variance from such regulations as outlined in Subsection F, Variance, below.
(2)
No permit is required to make maintenance repairs to or to replace parts of existing structures which do not enlarge or increase the height of an existing structure.
F.
Variance.
(1)
Any request for a variance shall include documentation in compliance with 14 Code of Federal Regulations Part 77 Subpart B (FAA Form 7460-1 (as amended or replaced). Determinations of whether to grant a variance will depend on the determinations made by the FAA and the Department's BOA as to the effect of the proposal on the operation of air navigation facilities and the safe, efficient use of navigable airspace. In particular, the request for a variance shall consider which of the following categories the FAA has placed the proposed construction in:
(a)
No objection. The subject construction is determined to not exceed obstruction standards, and marking/lighting is not required to mitigate potential hazard. Under this determination, a variance shall be granted.
(b)
Conditional determination. The proposed construction/alteration is determined to create some level of encroachment into an airport hazard area which can be effectively mitigated. Under this determination, a variance shall be granted contingent upon implementation of mitigating measures as described in Subsection I, Obstruction marking and lighting, below.
(c)
Objectionable. The proposed construction/alteration is determined to be a hazard and is thus objectionable. A variance shall be denied, and the reasons for this determination shall be outlined to the applicant.
(2)
Such requests for variances shall be granted where it is duly found that a literal application or enforcement of the regulations will result in unnecessary hardship and that relief granted will not be contrary to the public interest, will not create a hazard to air navigation, will do substantial justice, and will be in accordance with the intent of this section.
G.
Use restrictions. Notwithstanding any other provisions of this section, no use shall be made of land or water within the Airport Overlay District in such a manner as to create electrical interference with navigational signals or radio communications between the airport and aircraft, make it difficult for pilots to distinguish between airport lights and others, impair visibility in the vicinity of the airport, create bird-strike hazards or otherwise endanger or interfere with the landing, takeoff or maneuvering of aircraft utilizing the Zelienople Airport.
H.
Preexisting nonconforming uses. The regulations prescribed by this section shall not be construed to require the removal, lowering, or other change or alteration of any structure or tree not conforming to the regulations as of the effective date of this section, or otherwise interfere with the continuance of a nonconforming use. No nonconforming use shall be structurally altered or permitted to grow higher so as to increase the nonconformity, and a nonconforming use, once substantially abated (subject to this chapter), may only be reestablished consistent with the provisions herein.
I.
Obstruction marking and lighting. Any permit or variance granted pursuant to the provisions of this section may be conditioned according to the process described in Subsection F, Variance, above, to require the person requesting the permit or variance, at the person's own expense, to install, operate, and maintain such marking or lighting as deemed necessary to assure both ground and air safety.
