(1) Delinquent service charges shall bear interest at the rate of 12 percent per annum, or such rate as may hereafter be authorized by law, computed on a monthly basis from the date of delinquency until paid. Interest shall be calculated at the rate in effect at the time of payment of the charges regardless of when the charges were first delinquent.

(2) The City shall have a lien for delinquent service charges, including interest thereon, against any property subject to service charges. The lien shall be superior to all other liens and encumbrances except general taxes and local and special assessments. Such lien shall be effective and shall be enforced and foreclosed in the same manner as the foreclosure of real property tax liens. The County may commence to foreclose a surface water management service charge lien after three years from the date surface water management charges become delinquent. Collections shall include costs of foreclosure in addition to service charges and interest. (Ord. 37-02 § 2 (9.08.100))
