In order to carry out the provisions of this subchapter, there are created and established certain zones which include all of the land lying beneath the approach, transitional, horizontal, and conical surfaces as they apply to Cleburne Regional Airport. Such zones are shown on Cleburne Regional Airport Zoning Map prepared by Coffman Associates, and adopted by City Council on December 13, 2022, which is attached to this subchapter and made a part hereof by reference. A copy of the map shall be made available upon request at the Cleburne Regional Airport administrative office. 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. The various zones are hereby established and defined as follows:
(A) Approach zones. Approach zones are hereby established beneath the approach surfaces at each end of Runway 15-33 at the airport. The approach surface shall have an inner edge width of 500 feet, which coincides with the width of the primary surface, at a distance of 200 feet beyond each runway end, widening thereafter uniformly to a width of 3,500 feet at a horizontal distance of 10,000 feet beyond the end of the primary surface. The centerline of the approach surface is the continuation of the centerline of the runway.
(B) Transitional zones. The transitional zones are the areas beneath the transitional surfaces. Transitional surface, symmetrically located on either side of the runway, have variable widths as shown on the Cleburne Regional Airport Hazard Zoning Map. Transitional surfaces extend outward perpendicular to the runway centerline and the extended runway centerline from the periphery of the primary surface and the approach surfaces to where they intersect the horizontal surface. Where the precision instrument runway approach surface projects through and beyond the conical surface, there are hereby established transitional zones beginning at the sides of and at the same elevation as the approach surface and extending for a horizontal distance of 5,000 feet as measured perpendicular to the extended runway centerline.
(C) Horizontal zone. The horizontal zone is established beneath the horizontal surface at the airport which is a plane 150 feet above the established airport elevation, the perimeter of which is constructed by swinging arcs of 10,000 feet radii from the center of each end of the primary surface of the runway and connecting the adjacent arcs by drawing lines tangent to those arcs. The horizontal zone does not include the approach and transitional zones.
(D) Conical zone. The conical zone is established as the area beneath the conical surface at the airport that commences at the periphery of the horizontal zone and extends outward there from a horizontal distance of 4,000 feet.
