For the purposes of this chapter, Thornbury Township is hereby
divided into classes of districts which shall be designated as follows:
C.
All land areas of the Township shall be deemed by this chapter to
be within a zoning district, and all buildings, structures, lots,
and land in the Township, except as provided herein or in other applicable
law, shall be subject to the provisions of the district in which they
are located. Buildings or structures may be constructed or used, and
lots, tracts, or land may be developed, used, or occupied only for
land uses, as primary or accessory uses-by-right, conditional uses
when approved by the Board of Supervisors, or uses by special exception
or variances when approved by the Zoning Hearing Board, which adhere
to standards and which are permitted in the zoning district where
the same are located.
A.
Names and boundaries of zoning districts shall be as shown on the
"Zoning Map of Thornbury Township" (Zoning Map) as may be amended.
Said map and all notations, references and other information shown
thereon shall be made part of and incorporated by reference into this
chapter.[1]
[1]
Editor's Note: The Zoning Map of Thornbury Township is included
as an attachment to this chapter.
C.
Applicable maps for other natural resource areas shall be as found
in the Township Comprehensive Plan, unless otherwise specified.
District boundaries shall be property, tract, or lot lines;
center lines of streets, lanes, railroads, watercourses, ponds, or
rights-of-way of power lines or other public utilities; and such lines
extended and parallel thereto, as existing at the effective date of
this chapter and amendments thereto. The following rules shall apply
where uncertainty exists as to the location of any boundary on the
Zoning Map:
A.
Where a district boundary is indicated as approximately following
the center line of a street, lane, railroad, watercourse, pond, or
right-of-way of a power line or other public utility, such center
line shall be construed to be the boundary.
B.
Where a district boundary is indicated as including both sides of
a street, lane, railroad, watercourse, pond, or right-of-way of a
power line, or other public utility, the district shall be construed
to apply to the entire bed of such and the boundary to follow the
edge of such.
C.
Where a district boundary is indicated as approximately following
a property, tract, or lot line, such line shall be construed to be
the boundary.
D.
Where a district boundary divides a lot or tract or runs through
undivided property, the location of such boundary, unless otherwise
specified by information on the Zoning Map, shall be determined by
the scale of said Map.
Where a district boundary divides a lot held in single and separate
ownership at the effective date of this chapter, use regulations applicable
to the less restrictive district may extend into that portion of said
lot in the more restrictive district to either the nearest lot line
or to a distance of 50 feet beyond the district boundary, whichever
is less. Full usage shall first be made of the area of the lot in
the less restrictive district before extension of a use into the portion
of the lot in the more restrictive district. Any extension of a use
into the more restrictive district must meet the area and bulk requirements
of the more restrictive district. For the purpose of this chapter,
the more restrictive district shall be the district with the greater
minimum lot size requirement. If the lot size requirements in both
districts are equal, the district with the greater setback requirements
shall be considered the more restrictive district.
Whenever federal, state or county owned property is included
in one or more zoning districts, it shall be subject to the provisions
of this chapter only insofar as is permitted by the Constitution and
Laws of the United States of America and the Commonwealth of Pennsylvania.
