At the time fixed by the governing body for hearing the petition and any objections filed thereto or at any postponement or continuance of such matter, the governing body shall hear the petition and objections and shall determine whether the consent of the owners of the requisite area has been obtained, whether notice has been duly given and whether the public interest will be prejudiced by the vacation of such plat or street or parts thereof. If such matters are determined in favor of the petition the governing body shall by ordinance make such determination a matter of record and vacate such plat or street; otherwise it shall deny the petition. The governing body may, upon hearing, grant the petition in part and deny it in part, and make such reservations, or either, as appear to be for the public interest.
