For the purpose of this chapter, the Township is hereby divided into districts, which shall be designated as follows:

The boundaries of said districts shall be shown upon the maps attached to and made a part of this chapter, which shall be designated the "Zoning Map" and "Floodplain Overlay Map." Said maps and all notations, references and other things shown thereon shall be made a part of this chapter, as if the matters and things shown by said maps were all fully described herein.[1]

Where uncertainty exists with respect to the boundaries of the various districts shown on the Zoning Map, the following rules shall apply:

In any case where a tract has for one of its boundaries a Township boundary line, then, for the purpose of this chapter, the existing zoning classification of the adjacent property in the neighboring municipality shall be determined and related to the most similar East Norriton Township zoning district. If the zoning classification in the neighboring municipality as related to the East Norriton Township Zoning Ordinance is more restrictive than the zoning classification of the property in East Norriton Township, then the East Norriton Township Zoning Ordinance regulations shall apply as if the neighboring property were in East Norriton Township.

Whenever federal- or state-owned property or property owned by any federal or state agency or political subdivision thereof, as well as public utilities, 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.
