(a) The boundaries of the districts as enumerated in section 29-3 of this chapter are hereby established and adopted as shown on the map which is hereby designated as the "Zoning District Map," and which map and all the notations, references and information shown thereon are hereby made as much a part of this chapter as if the same were set forth in full herein. It shall be the duty of the director of public works to keep on file in his office an authentic copy of such district map, and duplicate copies thereof, showing all the changes, amendments or additions thereto. When definite distances in feet are not shown on the zoning district map, the district boundaries on the zoning district map are intended to be along the existing street, alley or plotted lines, or extension of the same, and if the exact location of such line is not clear, it shall be determined by the director of public works, due consideration being given to location as indicated by the scale of the zoning district map.

    (b) When streets or alleys on the ground differ from the streets or alleys as shown on the zoning district map, the director of public works may apply the district designations on the map to the streets or alleys on the ground in such manner as to conform to the intent and purpose of this chapter.

    (c) Whenever any street or alley is vacated, the particular district in which the adjacent property lies shall be automatically extended to the centerline of any such street or alley.

    (d) Except as provided in subsection (f), all territory which may hereafter be annexed to the city shall automatically be placed in zoning district R-1 for a period of not more than six (6) months.

    (e) During the six-month period referred to in (d) herein, the commission shall proceed to recommend permanent zoning to the council in the manner prescribed by law, within three (3) months, and the council shall act on the recommendations in the normal manner in the remaining three (3) months, causing permanent zoning districts to be created and having the zoning district map changed to incorporate the permanent district lines.

    (f) A petitioner for annexation may request that the petitioner's property in the area proposed to be annexed be placed in one or more specified zoning districts upon annexation. Except as modified by this section, the procedures set forth in section 29-34(a) and (c) shall apply to such zoning requests. When a request for zoning has been made under this subsection, the ordinance annexing the area shall place the area in one or more zoning districts. If the proposed annexation ordinance would place any property in the area to be annexed in a district other than that requested, the petition for annexation may be withdrawn at any time before passage of the ordinance.
