The boundaries on the districts enumerated in § 600-701 are hereby established on a map entitled "Zoning Map of the City of Reading," which map accompanies and is hereby declared to be a part of this chapter. Where uncertainty exists as to the precise location of the boundaries shown on said map, the following rules shall apply:
A. District boundary lines generally follow the center line of streets, alleys and streams, and lot or property lines as they exist on plans of record at the time of adoption of this chapter. Where a district boundary line divides a lot, the location of said boundary, unless the same is identified by dimensions, shall be determined by use of the scale on the map.
B. Where a district boundary is not fixed by dimensions and where it approximately follows a lot line, such lot line shall be construed to be along such lot line unless specifically shown otherwise.
C. In case any further uncertainty exists, the Zoning Administrator shall interpret the intent of the map as to the location of the district boundary lines.
