In expansion of the declaration of legislative intent and statement of community development objectives in §§
500-101 and
500-102 of Article
I of this chapter, it is the intent of this article to benefit the public health, safety and welfare by regulating and restricting the height of man-made and natural objects in the vicinity of any airport located in Upper Hanover Township in conformance with the following objectives.
A. Create appropriate overlay zones and establish boundaries
thereof.
B. Provide for changes in the restrictions and boundaries
of such zones in accord with particular types of airports, runways,
aircraft and instrumentation involved.
C. Define certain terms used herein (other terms are defined in Article
II, Definitions, under "airport-zoning-related terms").
D. Provide a map of the overlay zones for each airport.
E. Provide rules for enforcement of these regulations.
F. Prevent the establishment of hazards to air navigation.
G. Conform with the goals of the Comprehensive Plan and
Open Space and Environmental Resource Protection Plan.
[Amended 2-13-2007 by Ord. No. 2007-01]
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 Upper Hanover Township. Such zones are shown on the Upper Hanover
Airport Zoning Map which is incorporated into this chapter 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:
A. 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 center line is the continuation of the center
line of the runway.
B. Utility Runway 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 the width of 2,000 feet at a horizontal distance of 5,000
feet from the primary surface. Its center line is the continuation
of the center line of the runway.
C. Runway Larger than Utility with a Visibility Minimum
as Low as 3/4 Mile Nonprecision Instrument 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 4,000 feet at a horizontal distance of 10,000
feet from the primary surface. Its center line is the continuation
of the center line of the runway.
D. 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 center line is the continuation
of the center line of the runway.
E. Heliport 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 500
feet at a horizontal distance of 4,000 feet from the primary surface.
F. Transitional Zones. The transitional zones are the
areas beneath the transitional surfaces.
G. Heliport Transitional Zones. These zones extend outward
from the side of the primary surface and the heliport approach zones
a horizontal distance of 250 feet from the primary surface center
line and the heliport approach zone center line.
H. Horizontal Zone. The horizontal zone is established
by swinging arcs of 5,000 feet radii 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.
I. 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.
Except as otherwise provided in this chapter,
no structure shall be erected, altered or maintained, and no tree
shall be allowed to grow in any zone created by this chapter to a
height in excess of the applicable height limit herein established
for such zone. Such applicable height limitations are hereby established
for each of the zones in question as follows:
A. Utility Runway 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 center line.
B. Utility Runway Nonprecision Instrument 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 center
line.
C. Runway Larger Than Utility with a Visibility Minimum
as Low as 3/4 Mile Nonprecision Instrument Approach Zone. Slopes 34
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 center line.
D. 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 center line; thence
slopes upward 40 feet horizontally for each foot vertically to an
additional horizontal distance of 40,000 feet along the extended runway
center line.
E. Heliport Approach Zone. Slopes eight feet outward
for each foot upward beginning at the end of and at the same elevation
as the primary surface and extending to a distance of 4,000 feet along
the heliport approach zone center line.
F. Transitional Zones. Slopes seven feet outward for
each foot upward beginning at the side 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. In addition to the
foregoing, there are established height limits sloping seven feet
outward for each foot upward beginning at the sides of and at 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 at the same elevation as the approach surface
and extending a horizontal distance of 5,000 feet measured at 90°
angles to the extended runway center line.
G. Heliport Transitional Zones. Slopes two feet outward
for each foot upward beginning at the sides of and at the same elevation
as the primary surface and the heliport approach zones and extending
a distance of 250 feet measured horizontally from and at 90° angles
to the primary surface center line and heliport approach zone center
line.
H. Horizontal Zone. Established at 150 feet above the
airport elevation.
I. 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.
Notwithstanding any other provisions of this
chapter, no use may be made on land or water within any zone established
by this chapter in such as 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.
Where there exists a conflict between any of
the regulations or limitations in this article and any other regulations
applicable to the same area, whether the conflict be with respect
to the height of structures or trees and the use of the land, or any
other matter, the more stringent limitation or requirement shall govern
and prevail.
