As used in this chapter, the following terms have the meanings as ascribed to them, unless the context otherwise requires:
AIRPORT: Vinita municipal airport, Vinita, Oklahoma.
AIRPORT ELEVATION: The highest point of an airport's usable landing area measured in feet from sea level. Vinita municipal airport has as elevation of six hundred ninety five feet (695') above mean sea level (MSL).
AIRPORT HAZARD: Any structure, object of natural growth or use of land which obstructs the airspace required for the flight of aircraft in landing or taking off at Vinita municipal 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 7-7-4 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 7-7-3 of this chapter.
BOARD OF ADJUSTMENT: A board consisting of five (5) members appointed by the city council of the city of Vinita as provided for by the laws of the state of Oklahoma, also known as the zoning board of adjustment (title 10, chapter 2 of this code).
CONICAL SURFACE: A surface extending outward and upward from the periphery of the horizontal surface at a slope of twenty (20) to one 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.
NONCONFORMING USE: Any preexisting structure, object of natural growth, or use of land which is inconsistent with the provisions of this chapter or an amendment thereto.
OBSTRUCTION: Any structure, growth, or other object, including a mobile object, which exceeds a limiting height set forth in section 7-7-4 of this chapter.
PERSON: An individual, firm, copartnership, corporation, company, association, joint stock association, or body politic; includes any trustee, receiver, assignee, or other similar representative thereof.
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. When the runway has no specially prepared hard surface, or planned hard surface, the primary surface ends at each end of that runway. The width of the primary surface is set forth in section 7-7-3 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.
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 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.
UTILITY RUNWAY: 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.
VISUAL RUNWAY: A runway intended solely for the operation of aircraft using visual approach procedures.
ZONING ADMINISTRATOR: The building inspector of the city of Vinita, also known as the codes enforcement officer and the zoning enforcement officer. (Ord. 3118, 10-5-1999)
