A. Street, Alley or Lot Lines. Where indicated zone boundaries are approximately street, alley or lot lines, such lines shall be construed to be the boundaries; otherwise such boundaries shall be determined by use of the scale appearing on the zoning maps unless specifically indicated by dimensions.

B. Determination by Commission. Where uncertainty exists, the Commission shall, by written decision, determine the location of the zone boundary, which decision shall be a final determination thereof.

C. Vacated Street or Alley. Where a street or alley is officially vacated, the property formerly in such street or alley shall be included within the zone of the adjoining property on either side thereof. In the event such street or alley was a boundary between two or more different zones, the new zone boundary shall be the former centerline of such vacated street or alley. (Ord. 1212 § 1, 1969; prior code § 33.402).
