Airport Hazard Area - 19.48

19.48.010. Airport Hazard Area

No material change shall be made in the use of land and no structure or tree shall be erected, planted, altered or otherwise established that would result in an obstruction into the airport hazard area of the Rangely airport. This regulation shall not be construed to require the removal, lowering or other changes of any structure of tree not conforming to this regulation as of its adoption date. The airport hazard area of the Rangely airport shall be defined as the volumetric zone of airspace above the combination of primary, approach and transitional surfaces of the airport as hereby defined.

  1. Primary Surface. A geometric plane which is defined as the surface longitudinally centered on:
    1. Runway 6/24 of the Rangely Airport; and,

    2. Runway 3/21 of the Rangely Airport. The dimensions of the primary surface(s) can generally be described as extending two hundred (200) feet beyond each end of the hard surface runways and is five hundred (500) feet in width for runway 6/24 and two-hundred fifty (250) feet in width for runway 3/21. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway centerline. The specific dimensions for the runways and primary surfaces are as follows: Runway Data Rangely Airpor

  Runway 6/24 Runway 3/21
  Existing Existing
Maximum elevation above mean sea level 5274’ 5243’
Actual runway length 6700’ >2400’
Actual runway width 75’ 60’
Primary surface length 7100’ 2800’
Primary surface width 500’ 250’
  1. Approach Surface. A geometric plane, which is defined as a sloping surface, that extends upward twenty (20) feet horizontally for each foot vertically from the ends of and at the same elevation as the primary surface, and extending to a horizontal distance of five thousand (5,000) feet along the extended runway centerline. The width of the inner edge of the approach surface coincides with the width of the primary surface ends and expands outward uniformly to a width of one thousand two hundred fifty (1,250) feet at the horizontal distance of five thousand (5,000) feet from the primary surface ends.
  2. Transitional Surface. A geometric plane which is defined as beginning as a sloping surface that extends from the sides of and at the same elevation as the primary surface and the approach surface at a slope of seven (7) feet horizontally for each foot vertically up to a. height of one hundred fifty (150) feet above the Rangely airport elevation of five thousand two hundred seventy four (5274) feet.
