Upon the recommendation of the city planning board, the city council may, by ordinance or resolution, vacate any street or alley within any such city without any petition being filed therefor. Before any such street or alley shall be vacated, the council shall appoint a committee of at least three members thereof, who shall faithfully and impartially and after reasonable notice to the owners and parties interested in property affected by such vacation, assess the damages, if any, to such owners and parties affected. They shall take into consideration the amount of special benefits, if any, arising from such vacation and shall file their report in writing with the city clerk. Any owner or party interested in property affected by such vacation, who shall file a written protest with such committee, may appeal from the adoption by the council of such appraisers' report in the manner provided in section 14-813, but such appeal shall not stay the passage of the ordinance or resolution vacating such street or alley. The award of appraisers shall be final and conclusive as the order of a court of general jurisdiction, unless appealed from. When the city vacates a street or alley, the city shall, within thirty days after the effective date of the vacation, file a certified copy of the vacating ordinance or resolution with the register of deeds for the county in which the vacated property is located to be indexed against all affected lots.
