As used in this chapter, unless the context otherwise requires, the following words and terms shall have the meanings ascribed to them in this section:
AIRPORT: The Council airport.
AIRPORT COMMISSION: A board consisting of three (3) members appointed by the city council of the city of Council, Idaho.
AIRPORT ELEVATION: Two thousand nine hundred sixty eight feet (2,968') 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 set forth in section 7-3-4 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 7-3-3 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 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 hereto.
OBSTRUCTION: Any structure, growth, or other object, including a mobile object, which exceeds a limiting height set forth in section 7-3-4 of this chapter.
PERSON: 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.
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 7-3-3 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 the 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: Those 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.
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. (Ord. 355B, 6-8-1999)
