The district boundary lines of the Zoning Map enclose an area of a designated district, and generally follow recorded lot lines, the centerline of streets, railroad rights of way or their extensions, provided, however, that:
   (a)   Where the district boundary line is shown by dimension or relationship as being located a specific distance from and/or parallel to a street line, said distance shall control.
   (b)   Where a district boundary line is shown as adjoining a railroad, it shall, unless otherwise fixed, be construed to coincide with the nearest boundary line of the railroad right of way.
   (c)   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.
   (d)   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 Zoning Map, it shall be determined by the scale appearing thereon and, in case of other uncertainties, the Planning Commission shall determine the exact location.
