Where uncertainty exists as to the boundaries of zoning districts as shown on the official zoning map, the following rules shall apply:
A. Boundaries indicated as approximately following the centerlines of streets, highways or alleys shall be construed to follow such centerlines.
B. Boundaries indicated as approximately following platted lot lines shall be construed as following such lot lines.
C. Boundaries indicated as approximately following city limits shall be construed as following such city limits.
D. Boundaries indicated as following railroad lines shall be construed to be midway between the main tracks.
E. Boundaries indicated as following shorelines shall be construed to follow such shorelines, and, in the event of change in the shorelines, shall be construed as moving with the actual shorelines; boundaries indicated as approximately following the centerline of streams, rivers, canals, lakes, or other bodies of water, shall be construed to follow such centerlines.
F. Boundaries indicated as parallel to, or extensions of, features indicated in subsections A through E of this section shall be so construed. Distances not specifically indicated on the official zoning map shall be determined by the scale of the map.
G. Where physical or cultural features existing on the ground are at variance with those shown on the official zoning map, or in other circumstances not covered by subsections A through F of this section, the city council shall interpret the district boundaries.
H. Where a zoning district boundary line divides a lot which was in single ownership at the time of passage of the ordinance codified in this title, the city council may permit, as a permitted conditional use, the extension of the regulations for either portion of the lot, unless the lot is naturally divided by reason of existing dissimilar uses.
