At the time appointed for the hearing of the right-of-way vacation petition, or at such time as the hearing may be adjourned to by the city council, the same shall be heard, and if the council determines to grant the petition, or any part thereof, the council shall authorize by ordinance the vacation of such right-of-way, or any portion thereof. Such ordinance may provide for the retention by the city of all easements or rights in respect to the vacated land for the construction, repair and maintenance of public utilities and services; provided, that the city council may, if no vested rights are impaired, modify, change, omit or add provisions or stipulations as a condition to the granting of petitions for vacations. When the city council deems it to the best interest of the city, it may waive all or any part of the additional costs and expenses provided for in this chapter with respect to any vacation; provided, that all conditions with respect to such vacation shall be fulfilled to the satisfaction of the city prior to the time of the introduction of an ordinance vacating a right-of-way, or all such conditions with respect to such vacation shall be fulfilled as specified in said ordinance prior to the ordinance becoming effective. Upon final passage of a right-of-way vacation ordinance, copies shall be distributed by the city clerk to all city departments having an interest in the ordinance.
