The boundaries between districts are, unless
otherwise indicated, either the center lines of streets, lanes, watercourses
and rights-of-way of power lines, and other public utilities, or such
lines extended, or lines parallel thereto. Where the boundaries of
a single district are indicated as including directly opposite sides
of a street, lane, lake or watercourse, or right-of-way of a power
line or other public utility for any portion of its length, the district
so indicated shall be construed to apply to the entire bed of such
street, lane, lake or watercourse, or right-of-way of such power line,
railroad, or other public utility, lying within such portion of its
length. Where uncertainty exists as to the location of any said boundaries
as shown on the Zoning Map, the following rules shall apply:
A. Where a district boundary is indicated as approximately
following the center line of a street, lane, lake or watercourse,
or right-of-way of a power line, or other public utility, such center
line shall be construed to be such boundary.
B. Where a district boundary is indicated as approximately
following a lot line or other boundary line, such lot line or property
line shall be construed to be such boundary.
C. Where a district boundary divides a lot or runs through
undivided property, the location of such boundary, unless otherwise
specified by figures on the Zoning Map, shall be determined by the
use of the scale appearing on said map, or by survey of a registered
surveyor or engineer.
D. Where figures are shown on the Zoning Map between
a street and a district boundary, they shall indicate that the district
boundary runs parallel to the street line at a distance therefrom
equivalent to the number of feet so indicated, unless otherwise specified.
Where scaled distances do not agree with such figures, the figures
shall control.
Whenever federal or state owned property is
included in one or more zoning districts, it shall be subject to the
provisions of this chapter only insofar as permitted by the Constitution
and laws of the United States of America and the Commonwealth of Pennsylvania.
Whenever municipally owned property is included
in one or more zoning districts, it shall not be subject to the provisions
of this chapter if, after a public hearing, the Board of Commissioners
shall decide that the facility, structure or use to occur on the premises
is reasonably necessary for the health, safety and welfare of the
public.
