The boundaries between districts are, unless otherwise indicated, intended to coincide with the limits of the Township; the center line of streets, roads, alleys or railroad rights-of-way; and with the side and rear lines of lots. Where figures are shown on the Zoning Map between a street, road, alley or railroad right-of-way and a district boundary line, they indicate that the district boundary line runs parallel to the street, road, alley or railroad right-of-way at a distance therefrom equivalent to the number of feet so indicated. Where any street or alley is hereafter officially vacated or abandoned, the regulations applicable to each parcel of abutting property shall apply to that portion of such street or alley added thereto by virtue of such vacation or abandonment. Any person aggrieved by the interpretation of the Zoning Map by the Zoning Officer concerning the location of the district boundaries may appeal to the Zoning Hearing Board for a determination.

Whenever a single lot two acres or less in size is located within two or more different zoning districts, the district regulations applicable to the district within which the larger portion of the lot lies shall apply to the entire lot. Whenever a single lot greater than two acres in size is located within two or more different zoning districts, each portion of that lot shall be subject to all the regulations applicable to the district in which it is located. Where a zoning district boundary line divides a lot and where distances from the boundary line to property lines are not specifically indicated on the Zoning Map, the exact boundary line location shall be determined by measurement, using the scale of the Zoning Map.

All land annexed to the Township after the effective date of this chapter shall be automatically assigned a zoning classification of R-1 (Low-Density Residential District) and shall remain so classified until a zoning plan for the annexed area has been adopted by the Board of Supervisors. The Planning Commission shall recommend to the Board of Supervisors appropriate zoning for the annexed area within 90 days of the effective date of such annexation.
