For the purposes of this chapter, the following words and phrases when used in this chapter are defined as follows:
"Airport"means the Hanford Municipal Airport.
"Airport elevation"means the highest point of the airport's usable landing area measured in feet from the sea level (245 feet).
"Approach surface"means the surface longitudinally centered on the extended runway center line, extending outward and upward from the end of the primary surface at a slope of 20 to one. In plan, the perimeter of the approach surface coincides with the perimeter of the approach zone.
"Conical surface"means a surface extending outward and upward from the periphery of the horizontal surface at a slope of 20 to one for a horizontal distance of 4,000 feet.
"Hazard to air navigation"means a height obstruction determined to have a substantial adverse effect on the safe and efficient utilization of the navigable airspace.
"Height"means, for the purpose of determining the height limits in all zones set forth in this chapter and shown on the airport zoning map, the datum mean sea level elevation, unless otherwise specified.
"Horizontal surface"means a horizontal plane 150 feet above the established airport elevation, the perimeter of which in plan coincides with the perimeter of the horizontal zone.
"Nonconforming use"means any preexisting structure, object of natural growth or use of land which is inconsistent with the provisions of this chapter or an amendment thereto.
"Nonprecision instrument runway"means 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.
"Obstruction"means any structure, growth or other object, including a mobile object, that exceeds a height limit set forth in Section
17.44.050.
"Primary surface"means a surface longitudinally centered on a runway. The primary surface extends 200 feet beyond each end of that runway. The width of the primary surface is 500 feet. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway center line.
"Runway"means a defined area on the airport prepared for the landing and takeoff of aircraft along its length.
"Structure"means an object, including a mobile object, constructed or installed by man, including, but without limitation, buildings, towers, cranes, smokestacks, earth formations, and overhead transmission lines.
"Transitional surface"means a surface which extends outward at 90 degree angle to the runway center line and the runway center line extended at a slope of seven feet horizontally for each foot vertically from the sides of the primary and approach surfaces to where they intersect the horizontal and conical surfaces.
"Tree"means any object of natural growth.
"Utility runway"means a runway that is constructed for, and intended to be used by, propeller driven aircraft of 12,500 pounds maximum gross weight and less.
"Visual runway"means a runway intended solely for the operation of aircraft using visual approach procedures.
