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 to 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 of 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, alley, 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 property 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.
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 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.
The Municipality of Norristown or its designees are exempt from
this chapter.
