RESOLUTION OF RECOMMENDATION TO THE BOARD OF COUNTY COMMISSIONERS
Moved by Ron Sommer that the following resolution be introduced for passage by the Weld County Planning
Commission. Be it resolved by the Weld County Planning Commission that the application for:
Amendments to Sections 50 and 51 of the Weld County Zoning Ordinance be introduced for passage by the
Weld County Planning Commission. The amendments will clarify airport elevation, reference point, and the
transitional zone of the A -P (Airport) Overlay District.
51.1.1 AIRPORT: Greeley -Weld County Airport, located in Sections 2 and 3, T5N, and Sections
26 and 35, R65W of the 6th P.M., Weld County, Colorado.
51.1.2 AIRPORT ELEVATION: The established elevation of the highest point on the usable
landing area (4,690 feet above sea level).
51.1.3 AIRPORT REFERENCE POINT: The point established as the geographic center of the
airport landing area. The reference point at Greeley -Weld County Airport is a point which
geographical coordinates are Latitude 40 degrees, 26 feet, 08 inches north and Longitude
104 degrees, 37 feet, 55 inches west.
51.1.9 HORIZONTAL SURFACE: A horizontal plane 150 feet above the established airport
elevation, the perimeter of which in plan coincides with the perimeter of the horizontal
zone (4,840 feet above sea level).
51.3.4 TRANSITIONAL ZONE: Slopes seven feet outward for each foot upward beginning at the
sides of and at the same elevation as the primary surface and the approach surface, and
extending to a height of 150 feet above the airport elevation which is 4,690 feet above
mean sea level. In addition to the foregoing, there are established height limits sloping
seven feet outward for each foot upward beginning at the sides of and the same elevation
as the approach surface, and extending to where they intersect the conical surface.
Where the precision instrument runway approach zone projects beyond the conical zone,
there are established height limits sloping seven feet outward for each foot upward
beginning at the sides of and the same elevation as the approach surface, and extending
a horizontal distance of 5,000 feet measured at 90 degree angles to the extended runway
centerline.
51.3.5 HORIZONTAL ZONE: Established at 150 feet above the airport elevation or at a height
of 4,840 feet above mean sea level.

plan or any other planning document.
51.1.15 PRIMARY SURFACE: A surface longitudinally centered on a runway extending 200 feet
beyond each end of that runway. The elevation of any point on the primary surface is the
same as the elevation of the nearest point on the runway centerline. The width of a

prepared by Isbill Associates, Inc., Airport Consultants, dated July 1, 1984, which is attached to this
Ordinance and 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:
51.2.1 UTILITY RUNWAY VISUAL APPROACH ZONE: The inner edge of this approach zone
coincides with the width of the primary surface and is 250 feet wide. The approach zone
expands outward uniformly to a width of 1,250 feet at a horizontal distance of 5,000 feet
from the primary surface. Its centerline is the continuation of the centerline of the runway.
952673

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 1,500 feet at a horizontal
distance of 5,000 feet from the primary surface. Its centerline is the continuation of the
centerline of the runway.
51.2.3 PRECISION INSTRUMENT RUNWAY APPROACH ZONE: 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 from the primary surface. Its centerline is the continuation of the
centerline of the runway.
51.2.4 TRANSITIONAL ZONE: The transitional zones are the areas beneath the transitional
surfaces.
51.2.5 HORIZONTAL ZONE: The horizontal zone is established by swinging arcs of 5,000 feet
radii for all runways designated utility or visual and 10,000 feet for all others 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 zones.
51.2.6 CONICAL ZONE: The conical zone is established as the area that commences at the
periphery of the horizontal zone and extends outward therefrom a horizontal distance of
4,000 feet.
51.3 AIRPORT ZONE HEIGHT LIMITATIONS: Except as otherwise provided in this Ordinance, no
structure shall be erected, altered, or maintained, and no tree shall be allowed to grow in any zone
created by this Ordinance to a height in excess of the applicable height herein established for such
zone. Such applicable height limitations are hereby established for each of the zones in question as
follows:
51.3.1 UTILITY RUNWAY VISUAL APPROACH ZONE: Slopes of 20 feet outward for each foot
upward beginning at the end of and at the same elevation as the primary surface and
extending to a horizontal distance of 5,000 feet along the extended runway centerline.
51.3.2 RUNWAY LARGER THAN UTILITY VISUAL APPROACH ZONE: Slopes 20 feet outward
for each foot upward beginning at the end of and at the same elevation as the primary
surface and extending to a horizontal distance of 5,000 feet along the extended runway
centerline.
51.3.3 PRECISION INSTRUMENT RUNWAY APPROACH ZONE: Slopes 50 feet outward for
each foot upward beginning at the end of and at the same elevation as the primary
surface and extending to a horizontal distance of 10,000 feet along the extended runway
centerline; thence slopes upward 40 feet horizontally for each foot vertically to an
additional horizontal distance of 40,000 feet along the extended runway centerline.
51.3.4 TRANSITIONAL ZONE: Slopes seven feet outward for each foot upward beginning at the
sides of and at the same elevation as the primary surface and the approach surface, and
extending to a height of 150 feet above the airport elevation which is 4x65$ 4,690 feet
above mean sea level. In addition to the foregoing, there are established height limits
sloping seven feet outward for each foot upward beginning at the sides of and the same
elevation as the approach surface, and extending to where they intersect the conical
surface. Where the precision instrument runway approach zone projects beyond the
conical zone, there are established height limits sloping seven feet outward for each foot
upward beginning at the sides of and the same elevation as the approach surface, and
extending a horizontal distance of 5,000 feet measured at 90 degree angles to the
extended runway centerline.
952673
51.3.5 HORIZONTAL ZONE: Established at 150 feet above the airport elevation or at a height
of 4,808 4,840 feet above mean sea level.
51.3.6 CONICAL ZONE: Slopes 20 feet outward for each foot upward beginning at the periphery
of the horizontal zone and at 150 feet above the airport elevation and extending to a
height of 350 feet above the airport elevation.
51.4 USE RESTRICTION: Notwithstanding any other provisions of this Section, no use may be made of
land or water within any zone established by this Section in such a manner as to create electrical
interference with navigational signals or radio communication between the airport and aircraft, make
it difficult for pilots to distinguish between airport lights and others, result in glare in the eyes of pilots
using the airport, impair visibility in the vicinity of the airport, create bird strike hazards, or otherwise
in any way endanger or interfere with the landing, takeoff, or maneuvering of aircraft intending to use
the airport.
