Whenever a street, alley or other public way is vacated by official action of the City Council, or whenever a street or alley area is franchised for building purposes, the zoning district line adjoining each side of such street, alley, or other public way shall be automatically extended to the centerline of such vacated street, alley, or way, and all areas so involved shall then and henceforth be subject to all regulations of the extended districts.

Where physical features of the ground are at variance with information shown on the official zoning district map, or if there arises a question as to how a parcel of property is zoned and such question cannot be resolved by the application of subsections 5.2.1.1. through 5.2.1.6, or the zoning of property is invalidated by a final judgment of a court of competent jurisdiction, the property shall be considered as classified R-1 - Residential District, temporarily. In an area determined to be temporarily classified as R-1 - Residential District, no person shall construct, add or alter any building or structure or cause the sale [same] to be done, nor shall any use be located therein or on the land which is not permitted in an R-1 - Residential District, unless and until such territory has been zoned to permit such use by the City Council. It shall be the duty of the City Council to determine a permanent zoning for such area as soon as practicable.
