As used in this chapter, unless the context otherwise requires:
AIRPORT: The Kingfisher Municipal Airport.
AIRPORT ELEVATION: One thousand sixty eight feet (1,068') above mean sea level.
APPROACH SURFACE: A surface longitudinally centered on the extended runway centerline, extending outward and upward from the end of the primary surface and at the same slope as the approach zone height limitation slope.
APPROACH, TRANSITIONAL, HORIZONTAL AND CONICAL ZONES: See section 8-5-4, "Zoning Overlay District", of this chapter.
BOARD OF ADJUSTMENT: The board of adjustment, created and acting under the powers of this chapter in section 8-5-7 of this chapter.
CONICAL SURFACE: A surface extending outward and upward from the periphery of the horizontal surface at a slope of twenty to one (20:1) for a horizontal distance of four thousand feet (4,000').
HAZARD TO AIR NAVIGATION: An obstruction determined to have a substantial adverse effect on the safe and efficient utilization of the navigable airspace.
HEIGHT: For the purpose of determining the height limits in all zones set forth in these overlay district regulations and shown on the official airport zoning overlay district map, the datum shall be mean sea level elevation unless otherwise specified.
HORIZONTAL SURFACE: A horizontal plane one hundred fifty feet (150') above the established airport elevation, the perimeter of which in plan coincides with the perimeter of the horizontal zone.
NONCONFORMING USE: Any preexisting structure, object of natural grown, or use of land which is inconsistent with the provisions of these airport zoning overlay district regulations or an amendment thereto.
NONPRECISION INSTRUMENT RUNWAY: A runway having an existing instrument approach procedure utilizing air navigation facilities with only horizontal guidance, or an area type navigation equipment, for which a straight-in nonprecision instrument approach procedure has been approved or planned.
OBSTRUCTION: Any structure, growth, or other object, including a mobile object which exceeds a limiting height set forth in these airport zoning overlay district regulations.
PERSON: An individual, firm, partnership, corporation, company, association, joint stock association or government entity, including a trustee, a receiver, an assignee, or a similar representative of any of them.
PLANNING AND ZONING COMMISSION: The presently constituted planning and zoning commission established in accordance with title 2, chapter 2 of this code.
PRIMARY SURFACE: A surface longitudinally centered on a runway. When the runway has a specially prepared hard surface, the primary surface extends two hundred feet (200') beyond each end of that runway; for military runways or when the runway has no specially prepared hard surface, or planned hard surface, the primary surface ends at each end of that runway. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway centerline.
RUNWAY: A defined area on an airport prepared for landing and take off of aircraft along its length.
STRUCTURE: An object, including a mobile object, constructed or installed by man, including, but without limitation, buildings, towers, cranes, smokestacks, earth formation, and overhead transmission lies.
TRANSITIONAL SURFACES: These surfaces extend outward at ninety degree (90o) angles to the runway centerline and the runway centerline extended at a slope of seven feet (7') 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 approach surfaces, which project through and beyond the limits of the conical surface, extend a distance of five thousand feet (5,000') measured horizontally from the edge of the approach surface and at ninety degree (90o) angles to the extended runway centerline.
TREE: Any object of natural growth.
VISUAL RUNWAY: A runway intended for the purpose of operation of aircraft using visual approach procedures. (2013 Code)
