(A) In order to carry out the provisions of this chapter, there are hereby created and established certain zones which include all of the land lying beneath the approach surfaces, transitional surfaces, horizontal surfaces and conical surfaces as they apply to the Municipal Airport. Such zones are shown on the Municipal Airport layout plan consisting of three sheets, prepared by Poe and Associates, Oklahoma City, Oklahoma, and dated April 17, 1978, a copy of which is on file in the office of the Town Clerk-Treasurer and is made a part hereof. An area located in more than one of the following zones is considered to be only in the zone with the more restrictive height limitation.
(B) The various zones are hereby established and defined as follows.
(1) Runway larger than utility visual approach zone. The inner edge of this runway approach zone coincides with the width of the primary surface and is 1,000 feet wide. The approach zone expands outward uniformly to a width of 1,500 feet at a horizontal distance of 5,000 feet from the primary surface. Its centerline is the continuation of the centerline of the runway.
(2) Runway larger than utility with visibility minimum as low as a three-fourths mile no precision instrument approach zone. The inner edge of this approach zone coincides with the width of the primary surface and is 1,000 feet wide. The approach zone expands outward uniformly to a width of 4,000 feet at a horizontal distance of 10,000 feet from the primary surface. Its centerline is the continuation of the centerline of the runway.
(3) Transitional zones. The transitional zones are the areas beneath the transitional surfaces.
(4) Horizontal zone. The horizontal zone is established by swinging arcs of 10,000 radii from the center of each end of the primary surface of each runway and connecting the adjacent arcs by drawing lines tangent to those arcs. The horizontal zone does not include the approach and transitional zones.
(5) Conical zone. The conical zone is established as the area that commences at the periphery of the horizontal zone and extends outward therefrom a horizontal distance of 4,000 feet.
