The commission in vacating any street or part of any street, or changing the name of any street, may include in one ordinance the change of name or the vacation or narrowing of more than one street, avenue, or alley, but before vacating any street or part thereof, or narrowing any street, the commission shall first pass a resolution declaring its intention to do so. The city manager or his duly authorized representative shall cause notice of such resolution to be served, in the manner that service of summons is required to be made in civil actions, upon all persons whose property abuts upon the portion of the street affected by the proposed vacation or narrowing, and by publication once in one newspaper of general circulation in the city as to all the persons who cannot be personally served. Said notice shall state the time and place at which objections can be heard before the city planning commission. Upon the report of the city planning commission approving the proposed vacation or narrowing, the commission may by ordinance declare such vacation or narrowing, and such order of the commission vacating or narrowing a street or alley which has been dedicated to public use by the proprietor shall, to the extent to which it is vacated or narrowed, operate as a revocation of the acceptance thereof by the commission, but the right of way and easement therein of any lot owner shall not be impaired thereby.
