Definitions. For the purpose of this Section, the following words and phrases shall have the meaning given herein.
An area of land or water that is used or intended to be used for the landing and takeoff of aircraft and includes its buildings and facilities, if any.
The highest point of an airport's usable landing area measured in feet from sea level.
A surface longitudinally centered on the extended runway center line, extending outward and upward from the end of the primary surface and at the same slope as the approach zone height limitation slope. In plan the perimeter of the approach surface coincides with the perimeter of the approach zone.
A surface extending outward and upward from the periphery of the horizontal surface at a slope of twenty (20) to one (1) for a horizontal distance of four thousand (4,000) feet.
A horizontal plane one hundred fifty (150) feet above the established airport elevation, the perimeter of which in plan coincides with the perimeter of the horizontal zone.
A runway that is constructed for and intended to be used by propeller-driven aircraft of greater than twelve thousand five hundred (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.
A structure, including a mobile structure, constructed or installed by man or a product of nature, including, but without limitation, buildings, towers, cranes, smokestacks, earth formations, trees, overhead transmission lines and utility poles.
An individual, firm, partnership, corporation, company, association, joint stock association or governmental entity; includes a trustee, a receiver, an assignee or a similar representative of any of them.
A runway having an existing instrument approach procedure utilizing an instrument landing system (ILS) or a precision 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.
A surface longitudinally centered on a runway. When the runway has a specially prepared hard surface, the primary surface extends two hundred (200) feet beyond each end of that runway; when the runway has no specially prepared hard surface or planned hard surface, the primary surface ends at each end of that runway.
A defined area on an airport prepared for landing and takeoff of aircraft along its length.
These surfaces extend outward at ninety degree (90°) angles to the runway center line and the runway center line extended at a slope of seven (7) feet horizontally for each foot vertically from the sides of the primary and approach surfaces to where they intersect the horizontal and conical surfaces. Transitional surfaces for those portions of the precision approach surfaces, which project through and beyond the limits of the conical surface, extend a distance of five thousand (5,000) feet measured horizontally from the edge of the approach surface and at ninety degree (90°) angles to the extended runway center line.
A runway that is constructed for and intended to be used by propeller-driven aircraft of twelve thousand five hundred (12,500) pounds maximum gross weight and less.
A runway intended solely for the operation of aircraft using visual approach procedures.
D.
Airport zones are hereby created and established in that part of the City of Wildwood and shall comprise all of the land lying beneath the City of Wildwood area airport approach surfaces, transitional surfaces, horizontal surfaces and conical surfaces. Except as otherwise provided in this Section, no object shall be erected, altered, maintained, planted or be allowed to grow in any zone created by this Chapter to a height in excess of the applicable height limitations herein established for such zone. A tract of land located in more than one (1) of the following zones shall be deemed to be in the zone with the more restrictive height limitation. Other regulations appearing in this Chapter that are inconsistent herewith are superseded to the extent of such inconsistency.
E.
The various zones and their height limitations are hereby established and defined as follows:
1.

Shall have a width at its inner edge coinciding with the width of the runway's primary surface, as defined in Subsection (F) and expanding outwardly to a width of one thousand two hundred fifty (1,250) feet at a horizontal distance of five thousand (5,000) feet from the primary surface. The center line of the approach zone shall be the continuation of the center line of the runway. The height limitations shall be established by an imaginary plane sloping twenty (20) feet outward for each foot upward, commencing at the end of and at the same elevation as the primary surface, as specified in Subsection (F), and extending to a horizontal distance of five thousand (5,000) feet along the extended runway center line.
2.

Shall have a width at its inner edge of five hundred (500) feet and expanding outwardly from the primary surface to a width of two thousand (2,000) feet at a horizontal distance of five thousand (5,000) feet from the primary surface. The center line of the approach zone shall be the continuation of the center line of the runway. The height limitation shall be established by an imaginary plane sloping twenty (20) feet outward for each foot upward, commencing at the end of and at the same elevation as the primary surface, as specified in Subsection (F), and extending to a horizontal distance of five thousand (5,000) feet along the extended runway center line.
3.

The center line of the approach zone shall be the continuation of the center line of the runway. The height limitations shall be established by an imaginary plane sloping thirty-four (34) feet outward for each foot upward commencing at the end of and at the same elevation as the primary surface, as specified in Subsection (F), and extending to a horizontal distance of ten thousand (10,000) feet along the extended runway center line.
4.
Larger Than Utility Runway With A Visibility Minimum Of Three-Fourths (3/4) Mile Non-Precision-Instrument Approach Zone. Shall have a width at its inner edge of one thousand (1,000) feet and expanding outwardly to a width of four thousand (4,000) feet at a horizontal distance of ten thousand (10,000) feet from the primary surface. The center line of the approach zone shall be the continuation of the center line of the runway. The height limitations shall be established by an imaginary plane sloping thirty-four (34) feet outward for each foot upward beginning at the end of and at the same elevation as the primary surface, as specified in Subsection (F), and extending to a horizontal distance of ten thousand (10,000) feet along the extended runway center line.

H.
Notwithstanding any other provisions of this Chapter, no use may be made of land or water within any zone established by this Section 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 hazard or otherwise in any way endanger or interfere with the landing, takeoff or maneuvering of aircraft intending to use the airport.
I.
The regulations prescribed by this Section shall not be construed to require the removal, lowering or other change or alteration of any object not conforming to the regulations as of the effective date of this Chapter or otherwise interfere with the continuance of the non-conforming use. Nothing contained herein shall require any change in the construction, alteration or intended use of any object, the construction or alteration of which was begun prior to the effective date of this Chapter and is diligently prosecuted. Notwithstanding the preceding provision of this Subsection (I), the owner of any existing non-conforming structure or tree is hereby required to permit the installation, operation and maintenance thereon of such markers and lights as shall be deemed necessary by the Director of the Department of Public Works to indicate to the operators of aircraft in the vicinity of the airport the presence of such airport obstruction.
