As used in this Chapter, unless the context otherwise requires,
the following terms shall have the meanings indicated:
AIRPORT
Penn Valley Airport, Snyder County, Pennsylvania.
AIRPORT ELEVATION
The highest point of an airport’s usable landing area
measured in feet from sea level.
APPROACH SURFACE
A surface longitudinally centered on the extended runway centerline, extending outward and upward from the end of the primary surface and at the same slope as the approach zone height limitation slope set forth in §
27-1803 of this Chapter. In plan, the perimeter of the approach surface coincides with the perimeter of the approach zone.
CONICAL SURFACE
A surface extending outward and upward from the periphery
of the horizontal surface at a slope of 20:1 for a horizontal distance
of 4,000 feet.
HAZARD TO AIR NAVIGATION
An obstruction determined to have a substantial adverse effect
on the safe and efficient utilization of the navigable airspace.
HEIGHT
For the purpose of determining the height limits in all zones
set forth in this Chapter and shown on the Zoning Map, the datum shall
be mean sea level elevation unless otherwise specified.
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 plane.
NONCONFORMING STRUCTURE
Any preexisting structure or object of natural growth which
is inconsistent with the provisions of this Chapter or an amendment
thereto.
NONPRECISION INSTRUMENT RUNWAY
A runway having an existing instrument approach procedure
utilizing air navigation facilities with only horizontal guidance
or area-type navigation equipment for which a straight-in non-precision
instrument approach procedure has been approved or planned.
OBSTRUCTION
Any structure, growth or other object, including a mobile object, which exceeds a limiting height set forth in §
27-1803 of this Chapter.
PERSON
An individual, firm, partnership, corporation, company, association,
joint-stock association or governmental entity; includes a trustee,
a receiver, an assignee or a similar representative of any of them.
PRIMARY SURFACE
A surface longitudinally centered on a runway. When the runway has a specially prepared hard surface, the primary surface extends 200 feet beyond each end of that runway. The width of the primary surface is set forth in §
27-1802 of this Chapter. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway center line.
RUNWAY
A defined area on an airport prepared for landing and takeoff
of aircraft along its length.
STRUCTURE
An object, including a mobile object, constructed or installed
by man, including, but without limitation, buildings, towers, cranes,
smokestacks, earth formation and overhead transmission lines.
TRANSITIONAL SURFACES
These surfaces extend outward at 90° angles to the runway
center line and the runway center line extended at a slope of seven
feet horizontally for each foot vertically from the sides of the primary
and approach surfaces to where they intersect the horizontal and conical
surfaces.
TREE
Any object of natural growth.
UTILITY RUNWAY
A runway that is constructed for and intended to be used
for aircraft of 12,500 pounds maximum gross weight and less.
VISUAL RUNWAY
A runway intended solely for the operation of aircraft using
visual approach procedures.
[Ord. 565, 11/17/1986]
All applications for zoning permits for the erection, alteration
or conversion of any structure or the alteration of any use of land
which structure or use may conflict with the requirements of this
