Where uncertainty exists as to the boundaries of any zone, the following rules shall apply:
A. Where such boundaries are indicated as approximately following street and alley lines or lot lines, such lines shall be construed to be such boundaries.
B. In the case of unsubdivided property, and where a zone boundary divides a lot, the location of such boundaries, unless the same are indicated by dimensions, shall be determined by use of the scale appearing on the Zoning Map.
C. Where a public street or alley if officially vacated or abandoned, the centerline of such vacated street or alley shall be established as the zone boundary and such vacated street or alley shall acquire the classification of the property to which it reverts.
D. Areas of dedicated streets or alleys and railroad rights-of-way, other than those which clearly have a zone as indicated on the Zoning Map, shall be deemed to be unclassified and, in the case of streets and alleys, permitted to be used only for purposes lawfully allowed by Article 6 of the Municipal Code and the California Vehicle Code. In the case of railroad rights-of-way, such right-of-way shall be permitted to be used solely for the purpose of accommodating tracks, signals, other operative devices, and the movement of rolling stock.
