Where uncertainty exists as to the boundaries of any zone as shown on the zoning map, the following shall apply:
(A) Street, alley or lot lines.
(1) Where indicated, zone boundaries are approximately street, alley or lot lines, the lines are determined to be the boundaries of the zone. Otherwise, the boundaries shall be determined by the dimensions shown on the Official Zoning Map. In the absence of a dimension the boundary shall be determined by use of the scale shown on said map.
(2) A street, alley, railroad or railway right-of-way, watercourse, channel or body of water included on the zoning map shall, unless otherwise indicated, be included within the zone of adjoining property on either side thereof; and where such street, alley, right-of-way, watercourse, channel or body of water serves as a boundary between two or more different zones, a line midway in such street, alley, right-of-way, and the like, extending in the general direction of the long dimension thereof, shall be considered the boundary between zones.
(B) Uncertainties. Where uncertainties exist, the Commission shall, by written decision, determine the location of the zone boundary or building setback line.
(C) Vacations. In the event that a vacated street, alley, right-of-way, or easement was the boundary between two zones, the new zone boundaries shall be at the new property line.
