Within 30 days after the City completes the repair of a sewer lateral or sewer main for which the property owner is liable, the operations director shall certify the costs, expenses and charges to the finance director. The finance director shall notify the owner of the costs, expenses and charges and that unless the costs, expenses and charges are paid within 30 days, they shall become a lien on the owner’s property. Unless the owner files written objection within 30 days of receiving notice, the finance director shall enter the costs, expenses and charges in the City lien docket and they shall become a lien on the property involved and conclusive to all parties. If the owner files written objection within 30 days of notice, the council shall set a date for a hearing on the objections and give notice of the hearing to the objector at least ten days before the date of the hearing. The council shall at the time specified hear the matter and make a determination which shall be conclusive unless an appeal is taken to the circuit court for Washington County within 30 days after the determination is made. If the time in which an appeal can be taken has expired and no appeal is pending, the finance director shall enter the lien in the City lien docket.
