conical surfaces as they apply to the Erie International Airport. Such zones
are shown on the Erie International Airport Height Limitation and Zoning District
Map prepared by the Pennsylvania Department of Transportation, Bureau of Aviation,
and dated Spring, 1989, which is
attached to 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 Surface Zone. Established
beneath the visual approach surface. The inner edge of this zone coincides
with the width of the primary surface and is 250 feet wide. The 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 Surface
Zone. Established beneath the nonprecision instrument approach surface. The
inner edge of this zone coincides with the width of the primary surface and
is 500 feet wide. The zone expands outward uniformly to a width of 2,000 feet

not include the approach surface and transitional surface zones.
I. Conical Surface Zone. Established beneath the conical
surface. This zone commences at the periphery of the horizontal surface 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 Surface 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.

of 40,000 feet along the extended runway center line.
G. Transitional Surface Zones. 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 732 feet above mean sea level.
In addition to the foregoing, when an airport has a precision instrument runway
approach 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 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 ninety-degree

foot upward beginning at the periphery of the horizontal surface and at 150
feet above the established airport elevation and extending to a height of
350 feet above the established airport elevation or at a height of 732 feet
above mean sea level.
J. Excepted height limitations. Nothing in this chapter
shall be construed as prohibiting the construction or maintenance of any structure,
or growth of any tree to a height up to 300 feet above the surface of the
land.
Joint Airport Zoning Board. Where any airport hazard appertaining to
an airport is located outside the territorial limits of the municipality encompassing
the airport, all of the municipalities involved may, by ordinance or resolution,
create a Joint Airport Zoning Board which shall have the same power to adopt,
administer and enforce airport zoning regulations applicable to the airport
hazard area in question as that vested (by the police power) in the municipality
within which the area is located. Each Joint Airport Zoning Board shall have
as members two representatives appointed by each municipality participating
in its creation and, in addition, a Chairman elected by a majority of the
members so appointed.
In any case in which it is desired to remove, lower or otherwise terminate
a nonconforming structure or use, or the approach protection necessary cannot,
because of constitutional limitations, be provided by airport zoning regulations,
or it appears advisable that the necessary approach protection be provided
by acquisition of property rights, rather than by airport zoning regulations,
the municipality within which the property or nonconforming use is located,
or the municipality or municipal authority owning the airport or served by
it, may acquire by purchase, grant or condemnation, in the manner provided
by the law under which municipalities are authorized to acquire real property
for public purposes, such air right, aviation easement or other estate or
interest in the property or nonconforming structure or use in question as
may be necessary to effectuate the purpose of this chapter. In the case of
the purchase of any property or any easement or estate, or interest therein,
or the acquisition thereof by the power of eminent domain, the municipality
making the purchase or exercising the power shall, in addition to the damages
for the taking, injury or destruction of property, also pay the cost of the
removal and relocation of any structure or any public utility which is required
to be moved to a new location.
Any person aggrieved, or any taxpayer affected, by any decision of the
Board of Adjustment, may appeal to the Court of Common Pleas as provided by
law. In cases where applicable law does not provide an appeal from a municipality
to a Board, a person or taxpayer may appeal from a decision of a municipality
or Joint Airport Zoning Board, as provided by law for similar zoning proceedings.
If any of the provisions of this chapter or the application thereof
to any person or circumstances are held invalid, such invalidity shall not
affect other provisions or applications of the ordinance which can be given
effect without the invalid provisions of this chapter are declared to be severable.
