A. Purposes.
(1) This section is adopted pursuant to the authority conferred by the State Airport Zoning Act, as amended and the State Municipalities Planning Code, as amended.
(2) It is hereby found that an obstruction has the potential for endangering the lives and property of users of Braden Airpark located in Forks Township, and property or occupants of land in its vicinity; that an obstruction may affect existing and future instrument approach minimums of Braden Airpark; and that an obstruction may reduce the size of areas available for the landing, takeoff, and maneuvering of aircraft, thus tending to destroy or impair the utility of Braden Airpark and the public investment therein. Accordingly, it is declared:
(a) That the creation of establishment of an obstruction has the potential of being a public nuisance and may injure the region served by Braden Airpark or its successor.
(b) That it is necessary in the interest of the public health, public safety, and general welfare that the creation or establishment of any obstructions that are a hazard to air navigation be prevented; and
(c) That the prevention of these obstructions should be accomplished, to the extent legally possible, by the exercise of the police power without compensation.
(3) It is further declared that the prevention of the creation or establishment of hazards to air navigation, the elimination, removal, alteration or mitigation of hazards to air navigation, or marking and lighting of obstructions are public purposes for which a political subdivision may raise and expend public funds and acquire land or interests in land.
B. Definitions. See
§ 200-41B for terms associated with airports.
C. Airport zones. In order to carry out the provisions of this chapter, there are hereby created and established certain zones which include all of the land lying beneath the approach surfaces, transitional surfaces, horizontal surfaces, and conical surfaces as they apply to Braden Airpark. Such zones are shown on the Airport Zoning Map - Braden Airpark, in an area shown as Braden Airpark, consisting of one sheet dated January 3, 1983, which was prepared under the direction of the Pennsylvania Department of Transportation and is hereby incorporated as part of this chapter. An area located in more than one of the following zones is considered to be only in the zone with the more restrictive height limitation. The various zones are hereby established and defined as follows:
(1) Utility runway visual approach zone. The inner edge of this approach zone coincides with the width of the primary surface and is 250 feet wide. The approach zone expands outward uniformly to a width of 1,250 feet at a horizontal distance 5,000 from the primary surface. Its center line is the continuation of the center line of the runway.
(2) Transitional zones. The transitional zones are the areas beneath the transitional surfaces.
(3) Horizontal zone. The horizontal zone is established by swinging arcs of 5,000 feet radii from the center of each end of the primary surface of each runway and connecting the adjacent arcs by drawing lines tangent to those arcs. The horizontal zones do not include the approach and transitional zones.
(4) Conical zone. The conical zone is established as the area that commences at the periphery of the horizontal zone and extends outward there from a horizontal distance of 4,000 feet.
D. Airport zone height limitations. Except as otherwise provided in this chapter, no structure shall be erected, altered, or maintained, and no tree shall be allowed to grow in any zone created by this chapter to a height in excess of the applicable height limit herein established for such zone. Such applicable height limitations are hereby established for each of the zones in question as follows:
(1) Utility runway visual approach zone. Slopes 20 feet outward for each foot upward beginning at the end of and at the same elevation as the primary surfaces and extending to a horizontal distance of 5,000 feet along the extending runway center line.
(2) Transitional zones. Slopes seven feet outward for each foot upward beginning at the sides of and at the same elevation as the primary surface and the approach surface, and extending to a height of 150 feet above the airport elevation which is 399 feet above mean sea level. In addition to the foregoing, there are established height limits sloping seven feet outward for each foot upward beginning at the sides of and at the same elevation as the approach surface, and extending to where they intersect the conical surface.
(3) Horizontal zone. Established at 150 feet above the airport elevation or at a height of 549 feet above mean sea level.
(4) Conical zone. Slopes 20 feet outward for each foot upward beginning at the periphery of the horizontal zone and at 150 feet above the airport elevation and extending to a height of 350 feet above the airport elevation.
(5) Excepted height limitations. Nothing in this chapter shall be construed as prohibiting the construction or maintenance of any structure, or growth of any tree to a height up to 50 feet above the surface of the land.
E. Use restrictions. Notwithstanding any other provisions of this chapter, no use may be made of land or water within any zone established by this chapter 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.
F. Nonconforming uses.
(1) Regulations not retroactive. The regulations prescribed by this chapter shall not be construed to require the removal, lowering, or otherwise change or alteration of any structure or tree not conforming to the regulations as of the effective date of this chapter, or otherwise interfere with the continuance of a nonconforming use. 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 chapter, and is diligently prosecuted.
(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 of such markers and lights as shall be deemed necessary 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 at the expense of Braden Airpark.
G. Permits. See
§ 200-41G for detailed infoirmation.
H. Enforcement. It shall be the duty of the Zoning Officer to administer and enforce the regulations prescribed herein.
I. Conflicting regulations. Where there exists a conflict between any of the regulations or limitations prescribed in this section and any other regulations applicable to the same area, whether the conflict be with respect to the height of structures or trees, and the use of land, or any other matter, the more stringent limitation or requirement shall govern and prevail.
