Where uncertainty exists with respect to the boundaries of any of the districts indicated on the Zoning Map, the following rules shall apply:
(a) In the case of boundaries indicated as approximately following the streets or highways, the centerlines of said streets or highways shall be construed to be such boundaries.
(b) Boundaries indicated as approximately following lot lines shall be construed as following such lot lines.
(c) Boundaries indicated as approximately following Village boundary lines shall be construed as following such Village boundaries.
(d) Boundaries indicated as approximately parallel to the centerlines of streets or highways shall be construed as being parallel thereto and at such distance therefrom as indicated on the Zoning Map. If no distance is given, such dimension shall be determined by the use of the scale shown on the Zoning Map.
(e) Boundaries following the shoreline of a stream, lake or other body of water shall be construed to follow such shorelines, and in the event of change in the shoreline shall be construed as moving with the actual shoreline; boundaries indicated as approximately following the centerline of streams, rivers, canals or other bodies of water shall be construed to follow such centerlines.
(f) Where the application of the aforesaid rules leaves a reasonable doubt as to the boundaries between two districts, the regulations of the more restrictive district shall govern the entire parcel in question, unless otherwise determined by the Board of Appeals after recommendation from the Planning Commission.
