PURPOSE: This section is intended to provide for the safe operation of aircraft into and out of the Cheyenne County Municipal Airport located in Section 27, Township 3 South, Range 40 West, in Cheyenne County, Kansas. The areas located within the Airport Hazard Area as described in this Section are hereby zoned as follows:

(a)   Airport Hazard Area Description - The Airport Hazard Area shall consist of Operation Zones, Approach Zones, Turning Zones and Transition Zones as described in this section.

(b)   Zone Descriptions

(1)   The Operation Zones are longitudinally centered on each existing or proposed runway.

(A) Length- For existing and proposed paved runways, the operation zones begin and end 200 feet beyond the end of each runway. For existing and proposed turf runways, the operation zones begin and end at the runway ends.

(B)  Width-For existing and proposed paved runways, the operation zones are 1,000 feet wide. For all other existing and proposed runways, the operation zones are 500 feet wide.

(C)  Height- The height limit of the operation zones is the same as the height of the nearest point on an existing or proposed runway or the surface of the ground, whichever is higher.

(2)   The Approach Zones extend from the end of each operation zone and are centered along the extended runway centerlines. The zones’ dimensions are:

(A)  Paved Runways

(i)    Length and Width - The approach zones extend 50,000 feet from the operation zone, measured along the extended runway centerline. The approach zones are 1,000 feet wide at the end nearest the runway and expand uniformly to 16,000 feet wide at the farthest end.

(ii)   Height Limit - The height limit of the approach zones begins at the elevation of the operation zone and rises one (1) foot vertically for every 50 feet horizontally (50:1), except that the height limit shall not exceed 150 feet above the nearest existing or proposed runway end within three (3) miles of that runway end.

(B)  Unpaved Runways

(i)    Length and Width - The approach zone extends three (3) miles from the operation zone, measured along the extended runway centerline. The approach zone is 500 feet wide at the end nearest the runway and expands uniformly to 3,700 feet wide at the far end.

(ii)   Height - The height limit of the approach zones begins at the elevation of the operation zone and rises one (1) foot vertically for every 40 feet horizontally (40:1) up to a maximum of 150 feet above the nearest existing or proposed runway end.

(C)  The Transition Zones extend outward at right angles to the runway centerline and upward at a rate of one (1) foot vertically for every seven (7) feet horizontally (7:1). The height limit of these zones begins at the height limit of the adjacent Operation Zones or Approach Zones. The Transition Zones end at a height of 150 feet above the nearest existing or proposed runway end.

(D)  The Turning Zones extends three (3) miles from the existing or planned airport property line, excluding the Operation Zones, Approach Zones, or Transition Zones. The height limit of the Turning Zones is 150 feet above the nearest existing or proposed runway end.

(c)   Height Restrictions-No building, transmission line, pole, tower, chimney, wires, or other structure or appurtenance of any kind or character shall hereafter be erected, constructed, repaired or established, nor shall any tree or other object of natural growth be allowed to grow, above the heights described in above in 4-1601B.

The boundaries, operation zones, approach zones, transition zones, and turning zones of the airport are indicated on the Zoning Map that accompanies and is hereby made a part of these regulations. A copy of the zoning shall at all times be on file in the office of the County Clerk, Cheyenne County, St. Francis, Kansas.

(a)   Permit Required - It shall hereafter be unlawful to erect, construct, reconstruct, repair, or establish any building, transmission line, pole, tower, chimney, wires, or any other structure or appurtenance within the Hazard Area without first obtaining a permit from Cheyenne County. It shall also be unlawful to plant or replant any tree or other object of natural growth without the necessary permit.

(b)   Exceptions - Within the Turning Zones, no permit shall be required for any construction or planting that is not higher than seventy-five (75) feet above the nearest existing or proposed runway end.

Within the hazard area, no non-conforming building, transmission line, pole, tower, chimney, wires, or other structure or appurtenance of any kind or character or object of natural growth shall hereafter be replaced, substantially reconstructed, repaired, altered, replanted or allowed to grow to a height above the heights permitted by these regulations, if such structures or objects of natural growth have been tom down, destroyed, have deteriorated or decayed to an extent of 80 percent or more of their original condition, or abandoned for a period of twelve months or more. Transmission lines and communication lines shall be interpreted as all poles, wires, guys and all other equipment necessary for the operation and maintenance of same within the regulated zone.

Whenever Cheyenne County determines that a specific structure or object exceeds the height restrictions and existed prior to the enactment of these regulations, the owner(s) and the lessor(s) of the premises on which the structure or object is located shall be notified in writing by the County. The owner(s) and lessor(s) shall, within a reasonable time, permit the marking and lighting of the structure or object. The cost of marking or lighting shall not be assessed against the owner or lessor of said premise.
