For the purposes of this chapter, the Township of Lower Pottsgrove is hereby divided into classes of districts which shall be designated as follows:

Such districts are hereinafter enumerated, established in the text of this chapter and confirmed on the Zoning Map.

The boundaries between districts are, unless otherwise indicated, either the center lines of roads and of rights-of-way of railroads and/or public utilities or such lines extended or lines parallel thereto. Where figures are shown on the Zoning Map between a road and a district boundary line, they indicate that the district boundary line runs parallel to the road line at a distance therefrom equivalent to the number of feet so indicated.

In undivided property, the district boundary lines on the Zoning Map shall be determined by use of the scale of the map.

When a district boundary line divides a lot held in single and separate ownership at the effective date of this chapter, the regulations as to the use in the less restricted district shall extend over the portion of the lot in the more restricted district a distance of not more than 50 feet beyond the district boundary line, provided that, in case of a lot other than a corner lot, the regulations as to the use in a less restricted district may extend a distance of more than 50 feet beyond the district boundary line when authorized as a special exception.

Whenever federal- or state-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.

Township-owned land and buildings. The provisions of this chapter shall not apply to land and buildings owned by Lower Pottsgrove Township and used for its governmental purposes.
