(A)   When definite distances in feet are not shown on the Zoning Map, the district boundaries on the Map are intended to be along existing street, alley or property lines or extensions of or from such lines. If the exact location of such lines are not clear, they shall be determined by either supplemental detail drawings or rules of interpretation adopted by the concurring vote of four members of the Board of Adjustment.

   (B)   When existing streets or alleys differ from the streets or alleys shown on the Zoning Map, the Board may apply the district designations on the Map to the actual property in such manner as to conform, in its judgment, to the intent and purpose of this section.

   (C)   Land or premises within a street, alley, park, cemetery or other undesignated area on the Zoning Map shall be governed by the regulations of the use, height and area district adjoining such land or premises. If such land or premises are adjoined by more than one class of use, height or area district, then portions of such land or premises shall be governed by the regulations of the use, height and area district nearest to such portion.
