When uncertainty exists with respect to the boundaries of districts as shown on the Official Zoning Map, the following rule shall apply.
(a) Delineation. District boundary lines are intended to follow the center lines of streets, highways, alleys, easements, and other rights-of-way: the center lines of streams or other water channels; of visual district boundaries or specified distances on the Official Zoning Map, dimensions or distances shall be determined by scaling the distance on the Official Zoning Map.
(b) Interpretation. When the physical or cultural features existing on the ground are at variance with those shown on the Official Zoning Map, the Newton Falls Planning and Zoning Commission shall interpret the district boundaries.
(c) Divided Lot. Where a district boundary divides a lot which was in single ownership at the time of passage of this ordinance, the Planning and Zoning Commission may permit, as a special exception, the extension of the regulations for either portion of the lot, not to exceed 50 feet beyond the district line into the remaining portion of the lot.
