A.   Where district boundaries approximately follow lot, alley or street lines, such lot lines and street and alley center lines shall be construed as the district boundaries.
   B.   If a district boundary divides a parcel and the boundary line location is not otherwise designated, the location of the boundary shall be determined by use of the scale appearing on the zoning map.
   C.   Where a public street or alley is officially vacated or abandoned, the property formerly in said street or alley shall be included within the district or districts of the adjoining property on either side of the center line of said vacated or abandoned street or alley.
