Designation of zone boundaries. The zone boundary lines are intended to follow the right-of-way lines of streets, existing lot and property lines, and Borough corporation lines, all as shown in the Zoning District Map; but where a zone boundary line does not follow such a line, its position is shown in the Zoning District Map by a specific dimension expressing its distance in feet from a street line or other boundary line as indicated, or by reference to a contour line delineated on the United States Geological Survey Maps.

Determination of locations for boundaries. In the event of uncertainty as to the true location of a zoning boundary line in a particular instance, any decision of the Zoning Officer may be appealed before the Zoning Hearing Board by any affected property owner. It shall be the duty of the Board to render its determination with respect thereto.

Division of a lot or parcel in single ownership. Where a zoning boundary line divides a lot or parcel in single ownership at the time of passage of this chapter, any use authorized or permitted in either zone may be extended a distance not to exceed 50 feet beyond the boundary of the zone in which such use is authorized or permitted.

Any land annexed to or made a part of the Borough subsequent to the adoption of this chapter shall immediately be classified as an R-1 Residential District as of the effective date of annexation.

Within 60 days from the effective date of any annexation proceedings, the Borough Planning Commission shall prepare and submit to the Borough Council a report and study of its recommendations for rezoning of the annexed territory. The Planning Commission shall hold at least one public hearing thereon before submitting its final report to the Council.

At its next regular meeting following receipt of the final report of the Planning Commission, the Borough Council shall authorize the necessary legislation to amend the Zoning Chapter and/or map in accordance with Article XXV hereof.
