(1) The City Council shall hold at least one public hearing prior to adoption or amendment of a methodology for any system development charge.

(2) The City Recorder shall maintain a list of persons who have made a written request for notification prior to adoption or amendment of a methodology for any system development charge. Written notice shall be mailed to persons on the list at least 90 days prior to the first hearing to adopt or amend a system development charge and the methodology supporting the adoption or amendment shall be available at least 60 days prior to the first hearing to adopt or amend. The failure of a person on the list to receive a notice that was mailed shall not invalidate the action of the city. The City Recorder may periodically delete names from the list, but at least 30 days prior to removing a name from the list must notify any person whose name is to be deleted that a new written request for notification is required if the person wishes to remain on the notification list.

(3) Provided, however, in the case of a change in the methodology for the system development charge for the regional sewage treatment plant, the required hearing may be held by the Regional Committee before it approves the change and the required notices may be sent by the secretary to the Regional Committee.
