As used in this chapter, the following terms have the meanings as ascribed to them, unless the context otherwise requires:
AIRPORT: Robert S. Kerr Airport.
AIRPORT ELEVATION: The highest point of an airport's usable landing area measured in feet from sea level. Robert S. Kerr Airport has an elevation of four hundred fifty one feet (451') above mean sea level (MSL).
AIRPORT HAZARD: Any structure or tree or use of land which obstructs the airspace required for the flight of aircraft in landing or taking off at Robert S. Kerr Airport or is otherwise hazardous to such landing or taking off of aircraft.
AIRPORT HAZARD AREA: Any area of land or water upon which an airport hazard might be established if not prevented as provided in this chapter.
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 set forth in section 10-3-4 of this chapter. In plan, the perimeter of the approach surface coincides with the perimeter of the approach zone.
APPROACH, TRANSITIONAL, HORIZONTAL, AND CONICAL ZONES: These zones are set forth in section 10-3-3 of this chapter.
BOARD OF ADJUSTMENT: A board consisting of five (5) members appointed by the city council of the city of Poteau as provided by the laws of the state of Oklahoma.
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 this chapter and shown on the zoning 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.
LARGER THAN UTILITY RUNWAY: 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. (Existing pavement strength for runway 18-36 is rated at 15,000 pounds single wheel. Future is projected to be 30,000 pounds single wheel.)
NONCONFORMING USE: Any preexisting structure, object of natural growth, or use of land that is inconsistent with the provisions of this chapter or an amendment thereto.
NONPRECISION INSTRUMENT RUNWAY: 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 nonprecision instrument approach procedure has been approved or planned. (Runway 18-36 existing nonprecision instrument approaches to runway 36 based on VOR/DME and to runways 18 and 36 based on GPS.)
OBSTRUCTION: Any structure, growth, or other object, including a mobile object, which exceeds a limiting height set forth in section 10-3-4 of this chapter.
PERSON: An individual, firm, partnership, corporation, company, association, joint stock association, or government entity; includes a trustee, a receiver, an assignee, or a similar representative of any of them.
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. The width of the primary surface is set forth in section 10-3-3 of this chapter. 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 takeoff of aircraft along its length. (Runway 18-36 at Robert S. Kerr Airport is 75 feet wide, 4,006 feet long existing. This chapter is based on the planned length of 5,006 feet.)
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 lines.
TRANSITIONAL SURFACES: These surfaces extend outward at ninety degree (90°) 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.
TREE: Any object of natural growth.
VISUAL RUNWAY: A runway intended solely for the operation of aircraft using visual approach procedures.
ZONING ADMINISTRATOR: Any city employee as may be so designated by the Poteau city council. (Ord. 652, 12-12-2005)
