Where uncertainty exists as to the boundaries of districts as shown on the official zoning map, the boundaries shall be interpreted as following the nearest logical line to that shown: where shown as approximately following platted lot lines, it shall be construed as following such lot lines; where shown as following approximately the city limits, railroad tracks, street centerlines, stream or water centerlines or shorelines, it shall be construed as following such lines. Boundaries indicated as extensions of or parallel to such lines shall be so construed and where distances are now shown on the map, they shall be determined by the scale of the map. Where boundaries cannot be so construed or interpreted, or where such boundaries seem in conflict with physical or cultural features on the land, the planning commission shall interpret such boundaries. (Ord. 817 § 2, 1996).
