All boundary lines between districts shown on the Zone Map shall be interpreted and determined as follows:
(a) Where boundaries apparently follow lot lines and are not more than ten feet therefrom, the lot lines shall be construed to be such boundaries.
(b) Where boundaries apparently follow streets or alleys, the centerlines of such streets or alleys shall be construed to be such boundaries.
(c) In all other cases, the location of any boundary line, unless indicated by dimensions on the Zone Map, shall be determined by use of the scale appearing thereon.
