The boundaries of said districts shall be shown upon the map attached to and made a part of this chapter, which shall be designated as the "Zoning Map."[1] The said map and all the notations, references and other data shown thereon are hereby incorporated by reference into this chapter as if all were fully described herein. The zoning district boundaries are described in § 175-115.
[1]
Editor's Note: The Zoning Map is on file in the office of the City Clerk and is available during regular office hours.
Where uncertainty exists as to boundaries of any district as shown on said Zoning Map, the following rules shall apply:
A. 
District boundary lines are intended to follow or be parallel to the center line of streets, streams and railroads and lot or property lines as they exist on plans on record at the time of the adoption of this chapter, unless such district boundary lines are fixed by dimensions as shown on the Zoning Map.
B. 
Where a district boundary is not fixed by dimensions and where it approximately follows lot lines or approved subdivision plans and where it does not scale more than 10 feet therefrom, such lot lines shall be construed to be such boundaries, unless specifically shown otherwise.
C. 
In unsubdivided land or where a district boundary divides a lot, the location of such boundary, unless the same is indicated by dimensions, shall be determined by the use of the scale appearing on the Zoning Map.
In case of any uncertainty, the Zoning Hearing Board shall interpret the intent of the map as to location of district boundaries.
In unsubdivided land where a district boundary line divides a lot held in single and separate ownership, the following rules shall apply:
A. 
The use in a less restricted district may 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 such extension does not extend the frontage of the less restricted district along a street.
B. 
The frontage of the less restricted district may extend over the portion of the lot in the more restricted district a distance of not more than 50 feet beyond the district line, provided that a special exception is granted by the Zoning Hearing Board.
The phrase "more restrictive uses" as employed in this chapter shall mean the following:
A. 
Those permitted in an F-1 District are the more restrictive.
B. 
All other uses are less restrictive in the order they are permitted in the districts shown: F-2, OS, R-1, R-2, HC, CB, NB and IP.
C. 
Where a use in specifically enumerated in a less restrictive district, such use shall not be permitted in a more restrictive district unless it is a specifically enumerated and permitted use therein, except as provided in § 175-9.
