• In order to carry out the purposes of this chapter, there are hereby created and established certain zones which include all of the land lying beneath the (1) approach surfaces; (2) transitional surfaces; (3) horizontal surfaces; and (4) conical surfaces as they apply to the airport. Such zones are shown on Harry S. Truman Airport Zoning Maps consisting of four sheets: (1) Airport Layout Plan, Drawing No. SKE 01-CE 5300–13 dated January 27, 1978, prepared by Parsons Panamerican Corporation and revised through April 14, 1980, identified as “1982 Airport Zoning in St. Thomas, 1 of 4”; (2) Approach Clear Zone Plan, prepared by Greiner Engineering Sciences, Inc., under FAA Project No. 74 1 A-78–0001–01–74, dated December 1976 and revised through April 25, 1978, identified as “1982 Airport Zoning in St. Thomas, 2 of 4”; (3) Airport Layout Plan, Phase One, prepared by J.E. Greiner Company, Inc., dated April 1973, identified as “1982 Airport Zoning in St. Thomas, 3 of 4”; and (4) Airport Hazard Zoning Map, Runway 9/27, prepared by the Virgin Islands Port Authority and identified as “1982 Airport Zoning in St. Thomas, 4 of 4”. Copies of said maps are attached to the original copy of the act creating this chapter and are 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. The various zones are hereby established and defined as follows:

  • (a) Runway Larger than Utility Visual Approach Zone—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 1,500 feet at a horizontal distance of 5,000 feet from the primary surface. The centerline of the zone is the continuation of the centerline of the runway.

  • (b) Runway Larger than Utility with a Visibility Minimum Greater than ¾ Mile Nonprecision Instrument Approach Zone—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 of 10,000 feet from the primary surface. The centerline of the zone is the continuation of the centerline of the runway.

  • (c) Transitional Zones—The areas beneath transitional surfaces.

  • (d) Horizontal Zone—The zone established by swinging arcs of 10,000 feet radii for all runways 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 zone.

  • (e) Conical Zone—The area that commences at the periphery of the horizontal zone and extends outward therefrom a horizon distance of 4,000 feet.
