The Official Zoning Map shall supersede the prior Map, in the event that the Map becomes damaged or destroyed, or for purposes of clarity due to a number of boundary changes, or to correct drafting errors or omissions; provided, however, any such adoption shall not have the effect of amending the original zoning ordinance or any subsequent amendment thereof. Where uncertainty exists as to the boundaries of districts as shown on the Official Zoning Map, the following rules shall apply:

1. 1.
   Boundaries indicated as approximately following the centerlines of streets, highways, alleys, or other public right-of-way shall be construed to follow such centerlines;
2. 2.
   Boundaries indicated as approximately following platted lot lines shall be construed as following such lot lines;
3. 3.
   Boundaries indicated as approximately following corporate limits shall be construed as following corporate limits;
4. 4.
   Boundaries indicated as approximately following section lines, quarter section lines, or quarter-quarter section lines shall be construed as following such lines;
5. 5.
   Boundaries indicated as following railroad lines shall be construed to be midway between the main tracks;
6. 6.
   Boundaries indicated as approximately following the centerlines of streams, creeks or other waterways shall be construed to follow such centerlines;
7. 7.
   Boundaries not capable of being determined in the previous paragraphs shall be as dimensioned on the Official Zoning Map or if not dimensioned shall be determined by the scale shown on the map.
