Except where referenced on the Zoning Map to a street or alley lines or other designated line by dimensions shown on such Map, the district boundary lines follow lot lines or the center lines of streets or alleys as they existed at the time of the adoption of this Zoning Ordinance; but where a district line obviously does not coincide with the lot lines or such center lines or where it is not designated by dimensions, it shall be determined by scaling.
