Should a request for consideration of a sewer billing be deemed reasonable by the City, one-half of the billing shall be paid, when due, pending final disposition by the City. The decision of the City shall be final and the balance owed, if any, shall be paid within seven days, or, a refund, if any, shall be paid within seven days. It is to be understood that any decision by the City shall not necessarily establish a precedent for any future request for the consideration of a sewer billing. (1993 Code 52.34)
