In addition to the zoning districts established in this chapter
and delineated on the zoning district map, all areas containing or
characterized by the features listed hereunder are established as
overlay districts in accordance with Section 605 of the Pennsylvania
Municipalities Planning Code.
The location of each overlay district is delineated on a map
depicting that overlay feature. These maps are adopted as a part of
the Zoning District Map.
A. Accuracy of overlay districts. Overlay districts may not include
all land or sites subject to the special features of the overlay district,
and not all land within the overlay district may actually contain
the special or limited feature.
B. Areas not included in overlay districts. It is the intent of this
article that the limitations on development which are imposed by the
overlay district regulations shall apply to all parcels which include
the regulated feature, whether or not the land is shown in the overlay
district. It shall be the responsibility of the applicant to establish
the presence or absence on the proposed site of all features subject
to regulation in this article.
C. Interpretation of overlay districts. If the zoning district map or
list is questioned, the burden of proof shall be upon the developer,
who shall submit information from a qualified professional or other
expert acceptable to the Township to demonstrate that the site in
question can be used in the manner proposed without violation of this
article.
The regulations contained in this article shall apply to the
use of parcels and structures in each overlay district. These restrictions
shall be in addition to other regulations in this article.
A. Limitations of intensity of development. The amount of site area
used or occupied by development is restricted as specified by the
applicable district regulations and as further restricted by the overlay
district regulations of this article.
B. Limitations on authorized uses in overlay districts. Uses in overlay
districts may be authorized by right, by conditional use, by special
exception, or by planned development subject to the applicable district
regulations and as further stated in the overlay district.
(1)
Uses permitted by conditional use. All uses by right in any
zoning district which are prohibited because of the regulations of
any overlay district may be permitted by conditional use in any overlay
district, provided the use complies with the specific regulations
of any overlay district, and uses permitted by conditional use may
be permitted by conditional use in any overlay district, provided
the use complies with the regulations of the particular overlay district.
(2)
Uses permitted by special exception. All uses by special exception
in any zoning district which are prohibited because of the regulation
of any overlay district may be permitted by special exception in any
overlay district, and uses permitted by special exception may be permitted
by special exception in any overlay district, provided the use complies
with the regulations of the particular overlay district.
(3)
Uses permitted by planned residential development. All uses
by planned residential development in any zoning district which are
prohibited because of the regulations of any overlay district may
be permitted by planned residential development in any overlay district,
provided the use complies with the specific regulations of any overlay
district, and uses permitted by planned residential development may
be permitted by planned residential development in any overlay district.
The purpose of this chapter is to create an Airport District
Overlay that considers safety issues around the Washington County
Airport, regulates and restricts the heights of constructed structures
and objects of natural growth, creates appropriate zones, establishing
the boundaries thereof and providing for changes in the restrictions
and boundaries of such zones, creates the permitting process for use
within said zones and provides for enforcement, assessment of violation
penalties, an appeals process, and judicial review.
The Airport District Overlay shall not modify the boundaries
of any underlying zoning district. Where identified, the Airport District
Overlay shall impose certain requirements on land use and construction
in addition to those contained in the underlying zoning district.
The following words and phrases when used in this article shall
have the meaning given to them in this section unless the context
clearly indicates otherwise.
AIRPORT ELEVATION
The highest point of an airport's usable landing area measured
in feet above sea level. The airport elevation of the Washington County
Airport is 1,184 feet.
AIRPORT HAZARD
Any structure or object, natural or man-made, or use of land
which obstructs the airspace required for flight or aircraft in landing
or taking off at an airport or is otherwise hazardous as defined in
14 CFR Part 77 and 74 Pa.C.S.A. § 5102.
AIRPORT HAZARD AREA
Any area of land or water upon which an airport hazard might
be established if not prevented as provided for in this chapter and
the Act 164 of 1984 (Pennsylvania Laws Relating to Aviation).
APPROACH SURFACE (ZONE)
An imaginary surface longitudinally centered on the extended
runway center line and extending outward and upward from each end
of the primary surface. An approach surface is applied to each end
of the runway based on the planned approach. The inner edge of the
approach surface is the same width as the primary surface and expands
uniformly depending on the planned approach. The approach surface
zone, as shown on Figure 1, Surface Areas, is derived from the approach surface.
CONICAL SURFACE (ZONE)
An imaginary surface extending outward and upward from the
periphery of the horizontal surface at a slope of 20 feet horizontally
to one foot vertically for a horizontal distance of 4,000 feet. The
conical surface zone, as shown on Figure 1, Surface Areas, is based on the conical surface.
DEPARTMENT
Pennsylvania Department of Transportation.
FAA
Federal Aviation Administration of the United States Department
of Transportation.
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 (ZONE)
An imaginary plane 150 feet above the established airport
elevation that is constructed by swinging arcs of various radii from
the center of the end of the primary surface and then connecting the
adjacent arc by tangent lines. The radius of each arc is based on
the planned approach. The horizontal surface zone, as shown on Figure
1, Surface Areas, is derived from the horizontal surface.
LARGER THAN UTILITY RUNWAY
A runway that is constructed for and intended to be used
by propeller driven aircraft of greater than 12,500 pounds maximum
gross weight and jet-powered aircraft.
NONCONFORMING USE
Any preexisting structure, object of natural growth, or use
of land 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 nonprecision
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 by this chapter.
PRECISION INSTRUMENT RUNWAY
A runway having an existing instrument approach procedure
utilizing an Instrument Landing System (ILS) or a Precisions Approach
Radar (PAR). It also means a runway for which a precision approach
system is planned and is so indicated on an approved airport layout
plan or any other planning document.
PRIMARY SURFACE (ZONE)
An imaginary surface longitudinally centered on the runway,
extending 200 feet beyond the end of paved runways or ending at each
end of turf runways. The elevation of any point on the primary surface
is the same as the elevation of the nearest point on the runway center
line. The primary surface zone, as shown on Figure 1, Surface Areas, is derived from the primary surface.
RUNWAY
A defined area of 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 SURFACE (ZONE)
An imaginary surface that extends outward and upward from
the edge of the primary surface to the horizontal surface at a slope
of seven feet horizontally to one foot vertically. The transitional
surface zone, as shown on Figure 1, Surface Areas, is derived from the transitional surface.
TREE
Any object of natural growth.
UTILITY RUNWAY
A runway that is constructed for and intended to be used
by propeller-driven aircraft of 12,500 pounds maximum gross weight
or less.
VISUAL RUNWAY
A runway intended solely for the operation of aircraft using
visual approach procedures.
There are hereby created and established certain zones within the Airport District Overlay ordinance, defined in §
460-705.04 and depicted on Figure 1, Surface Areas, and illustrated on the Washington County Airport Hazard
Area Map, hereby adopted as part of this chapter, which include:
E. Transitional Surface Zone.
Notwithstanding any other provisions of this chapter, no use
shall be made of land or water within the Airport District Overlay
in such a manner as to create electrical interference with navigational
signals or radio communications between the airport and aircraft,
make it difficult for pilots to distinguish between airport lights
and others, impair visibility in the vicinity of the airport, create
bird strike hazards or otherwise endanger or interfere with the landing,
takeoff or maneuvering of aircraft utilizing the Washington County
Airport.
The regulations prescribed by this chapter shall not be construed
to require the removal, lowering, or other change or alteration of
any structure or tree not conforming to the regulations as of the
effective date of this chapter or otherwise interfere with the continuance
of a nonconforming use. No nonconforming use shall be structurally
altered or permitted to grow higher, so as to increase the nonconformity,
and a nonconforming use, once substantially abated (subject to the
underlying zoning ordinance), may only be reestablished consistent
with the provisions herein.
Any permit or variance granted pursuant to the provisions of this chapter may be conditioned according to the process described in §
460-705.06 to require the owner of the structure or object of natural growth in question to permit the municipality, at its own expense, or require the person requesting the permit or variance, to install, operate, and maintain such marking or lighting as deemed necessary to assure both ground and air safety.
Subject to that in this chapter.
Subject to the process in this chapter.
Where there exists a conflict between any of the regulations
or limitations prescribed in this chapter and any other regulation
applicable to the same area, the more stringent limitation or requirement
shall govern and prevail.
The purpose of the MPO Master Plan Overlay is to provide property
owners in the Township with opportunity to create mixed-use development
inclusive of residential and nonresidential land uses in areas of
the municipality that have existing infrastructure and capacity to
support redevelopment limited residential dwellings alongside moderately
sized commercial uses. Oriented to create a pedestrian experience,
this mixed-use area promotes walkability of residents and visitors
to promote increased mobility and animate the commercial spaces.
All unified mixed-use development shall comply with the regulations and requirements set forth by §
460-706.09. If any standards or requirements set forth by §
460-706.09 conflict with those in this chapter, the regulations and requirements of §
460-706.09 shall supersede.
A. Minimum lot size.
(1) Unified mixed-use development: one acre.
B. Minimum lot width: 40 feet.
C. Maximum lot coverage (impervious surface coverage): 70%.
D. Minimum front yard: 20 feet.
E. Minimum side yard: five feet.
F. Minimum rear yard: five feet.
H. Permitted projections into yards: see §
460-1403.
I. Maximum height.
(1) Principal structure: 60 feet.
(2) Accessory structure: 20 feet.
See §460- 706.09 and § 1605, as applicable.
