§ 155.04 AIRPORT HEIGHT RESTRICTION ZONES.
   (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 Colorado City Municipal Airport. Such zones are shown on the Colorado City Municipal Airport Federal Aviation Regulation (FAR) Part 77 Airspace Drawing. Three original, official, and identical copies of the FAR Part 77 Airspace Drawing reflecting the boundaries of the airport height restriction overlay zoning districts of the Town of Colorado City, Arizona are hereby adopted, and the Commissioner and Colorado City Town Clerk are hereby authorized to sign and attest each map as the official Colorado City Municipal Airport FAR Part 77 Airspace Drawing of the Town of Colorado City, Arizona, and such maps shall be filed and maintained as follows:
      (1)   One copy shall be filed for permanent record in the office of the Colorado City Town Clerk and shall be designated as Exhibit 1. This copy shall not be changed in any manner.
      (2)   One copy shall be filed in the Planning and Zoning Department and shall be designated as Exhibit 2. This copy shall be maintained by the Planning and Zoning Department by posting thereon all subsequent changes and amendments.
      (3)   One copy shall be filed in the office of the Airport Manager and shall be designated as Exhibit 3. This copy shall be maintained by the Airport Manager by posting thereon all subsequent changes and amendments.
   (B)   Each portion of an area located in more than one of the following zones shall be evaluated independently according to the zone in which it is located. The various zones are hereby established and defined as follows:
      (1)   Precision instrument runway approach zone (larger than utility runway). 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 16,000 feet at a horizontal distance of 50,000 feet. Its centerline is the continuation of the centerline of the runway.
      (2)   Nonprecision instrument runway approach zone (larger than utility runway). The inner edge of this approach zone coincides with the width of the primary surface and is 500 feet wide. The approach zone expands outward uniformly to a width of 3,500 feet at a horizontal distance 10,000 feet from the primary surface. Its centerline is the continuation of the centerline of the runway.
      (3)   Nonprecision instrument runway approach zone (utility aircraft). The inner edge of this approach zone coincides with the width of the primary surface and is 500 feet wide. The approach zone expands outward uniformly to a width of 2,000 feet at a horizontal distance 5,000 feet from the primary surface. Its centerline is the continuation of the centerline of the runway.
      (4)   Visual runway approach zone (larger than utility runway). The inner edge of this approach zone coincides with the width of the primary surface and is 500 feet wide. The approach surface expands uniformly to a width of 1,500 feet at a horizontal distance 5,000 feet from the primary surface. Its centerline is the continuation of the centerline of the runway.
      (5)   Visual runway approach zone (utility aircraft). The inner edge of this approach zone coincides with the width of the primary surface and is 250 feet wide. The approach surface expands uniformly to a width of 1,250 feet at a horizontal distance of 5,000 feet from the primary surface. The centerline of the approach zone is a continuation of the centerline of the runway.
      (6)   Transitional zone. The transitional zones are the areas beneath the transitional surfaces.
      (7)   Horizontal zone. The horizontal zone is established by swinging arcs of 5,000 or 10,000 feet radii from the center of each end of the primary surface of the primary runway and connecting the adjacent arcs by drawing lines tangent to those arcs. The horizontal zone does not include the approach and transitional zones. The horizontal zone was constructed with 10,000 feet radii.
      (8)   Conical zone. The conical zone is established as the area that commences at the periphery of the horizontal zone and extends outward there from a horizontal distance of 4,000 feet.
