Except where referenced on the Zoning Map to a street or alley line or other designated line by dimensions shown on such Map, the district boundary lines follow lot lines or the centerlines of streets or alleys as they existed at the time of the adoption of this Zoning Code (Ordinance 1420, passed February 28, 1966), but where a district line obviously does not coincide with the lot lines or such centerlines or where it is not designated by dimensions, it shall be determined by scaling.
(Ord. 1420. Passed 2-28-66.)
