The locations and boundaries of such districts shall be as shown upon the map attached to and hereby made a part of this chapter,[1] which shall be designated "Zoning Map of the Borough of East Greenville," hereinafter referred to in this chapter as "Zoning Map." Said map and all the notations, references and other data thereon shall be as much a part of this chapter as if fully described herein.
[1]
Editor's Note: Said map is on file in the Borough offices.
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, land, 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 property lines, such lot 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, state or Borough-owned property or property owned by any federal or state agency or any political subdivision thereof 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 of the Commonwealth of Pennsylvania. In the case of municipally owned property, the provisions of this chapter shall not apply.
