SEC. 16-17.  RULES FOR ZONES WHERE BOUNDARIES UNCERTAIN.
   Where uncertainty exists as to the boundaries of any zone shown on the zoning map, 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 locations of such boundaries, unless the same are indicated by dimensions, shall be determined by use of the scale appearing on such zoning map.
   (C)   Where a public street or alley or any private right-of-way or easement of any railroad, railway, canal, transportation or public utility company, is vacated or abandoned, the zoning regulations applicable to abutting property shall apply to such vacated or abandoned street, alley or property.
   (D)   All property in the city not otherwise classified, and all property hereinafter annexed and not zoned upon annexation, is hereby classified as R-1, excepting property developed as school sites, which shall be classified as R-2.
