SECTION 621. PUBLISHING OF LEGAL NOTICES.
   The City Council shall designate one newspaper circulated in the City for the publication of all notices and other matters required to be published in a newspaper. When possible, a change to another newspaper shall not be made until a notice of the intention to change is published in the previously designated newspaper.
   The charges for such publications in the designated newspaper shall not exceed the rates charged to the general public for similar publications.
   All legal notices or other matters required to be published shall also be posted in at least three public places within the City.
   Posting of legal notices in three public places shall be sufficient, without publication if the designated newspaper is unavailable and a suitable replacement cannot be designated.
