A. Pursuant to RCW 36.89.090, Pierce County shall place a lien on any parcel with a delinquent service charge, including interest thereon. Such liens shall be effective and shall be enforced in the same manner as provided for sewerage liens of cities and towns by RCW 35.67.200 through 35.67.290, except that the service charge lien shall be effective for a total not to exceed one year's delinquent service charges without the necessity of any writing or recording of the lien with the County Auditor, as provided for in RCW 36.89.093, in lieu of the provisions provided for in RCW 35.67.210, and except that the lien shall be foreclosed in the same manner as the foreclosure of real property tax liens, as authorized by RCW 36.94.150 and RCW 36.89.090. In accordance with RCW 36.89.094, the County may commence to foreclose a service charge lien after three years from the date surface water management charges become delinquent, in lieu of the provisions provided for in RCW 35.67.230.

B. Delinquent service charges shall bear interest provided in RCW 36.89.090, RCW 36.89.092, and RCW 35.67.200 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.
