(A) Where a district boundary approximately follows a lot, alley, or street line, the lot line and street and alley centerlines shall be construed as the district boundary.
(B) In unsubdivided property, and where a district boundary divides a parcel and the boundary line location is not specified by dimensions printed on the land use district map, the location of the boundary will be determined by using the scale appearing on the map.
(C) Where a public street or alley is officially vacated or abandoned, the regulations applicable to the property to which it reverts shall apply to the vacated or abandoned street or alley.
(2) If the Director determines that the above rules do not resolve uncertainty about a boundary location, the Commission shall determine the location of the boundary.
