Wherever any uncertainty exists as to the boundary of any zoning district as shown on the zoning map incorporated herein, the following rules shall apply:
(A) Where district boundary lines are indicated as following streets, alleys, or similar rights-of-way, they shall be construed as following the center lines thereof.
(B) Where district boundary lines are indicated as approximately following lot lines, such lot lines shall be construed to be such boundaries.
(C) Where a lot held in one ownership and of record at the effective date of this chapter is divided by a district boundary line, the entire lot shall be construed to be within the less restricted district; provided that this construction shall not apply if it increases the area of the less restricted portion of the lot by more than 20%.
