An area enclosed by a district boundary line, as shown on the Zoning Map, shall be in the district designated therein. In cases of uncertainty as to boundaries on the Zoning Map, the following rules shall apply:
(a) Where a boundary line appears within a street or other right-of-way, the boundary line shall be deemed to be the centerline of the street or other right-of-way.
(b) Where a boundary line appears to follow a lot line, such a lot line shall be deemed to be the boundary line.
(c) In the case of parks and cemeteries, the boundary shall be deemed to coincide with the boundary line of the park or cemetery.
(d) Where a boundary line coincides with a railroad, it shall, unless otherwise fixed, be considered to coincide with the boundary line of the railroad right-of-way.
(e) Where a district boundary line divides a parcel of land, the location of such boundary, unless related to fixed points on the property boundary, shall be determined by scale, and each part of the parcel shall comply with the regulations of the district in which it is located.
(f) Where the boundary of a district follows a stream, lake or other body of water, said boundary line shall be deemed to be at the centerline of such stream, lake or other body of water, unless such boundary line is fixed by dimensions shown on the Zoning Map.
(g) Where a district boundary line does not coincide with any of the aforesaid lines and where it is not located by dimensions or fixed points shown on the Map, it shall be determined by the scale appearing thereon, and, in cases of other uncertainties, the Board of Zoning Appeals shall determine the exact location.
