Editor's Note: The Official Zoning Map, as amended, is on file in the Borough offices; a copy of the Map is included at the end of this chapter. Zoning Map Amendments are listed in a table at the end of this chapter.
A. 
The boundaries between districts are, unless otherwise indicated, either the center lines of streets, alleys or railroad rights-of-way, or such lines extended or lines parallel thereto. Where figures are shown on the Zoning Map between a street and a district boundary line, they indicate that the district boundary line runs parallel to the street line at a distance therefrom equivalent to the number of feet so indicated.
B. 
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 a 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.
