A. Where an amendment to the Official Zoning Map is accompanied by a legal description of the zoning boundary, that legal description shall be interpreted as the zoning boundary line, regardless of the accuracy of the zoning boundary line drawn on the Official Zoning Map.
B. Where uncertainty exists as to the boundaries of districts as shown on the Official Zoning Map, the following rules shall apply:
1. Boundaries indicated as approximately following the centerline of streets, highways, or alleys shall be construed to follow such centerline;
2. Boundaries indicated as approximately following platted or deeded lot lines shall be construed as following such lot lines;
3. Boundaries indicated as approximately following municipal limits shall be construed as following such municipal limits;
4. Boundaries indicated as following railroad lines shall be construed to be midway between the main tracks;
5. Boundaries indicated as following shore lines shall be construed to follow such shore lines, and in the event of change in the shore line shall be construed as moving with the actual shore line; boundaries indicated as approximately following the centerline of streams, rivers, canals, lakes, or other bodies of water shall be construed to follow such centerline;
6. Boundaries indicated as parallel to or extensions of features indicated in subsections B.1 through B.5 above shall be so construed. Distances not specifically indicated on the Official Zoning Map shall be determined by the scale of the map;
7. 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 B.1 through B.6 above, the Board of Zoning Appeals shall interpret the district boundaries; and
8. Where a district boundary line divides a lot which was in single ownership at the time of passage of this code, the Board of Zoning Appeals may permit, as a variance, the extension of the regulations for either portion of the lot not to exceed fifty (50) feet beyond the district line into the remaining portion of the lot.
