If any assessment is not paid within five (5) days after its confirmation by the Board, the amount of the assessment shall become a lien upon the property against which the assessment is made by the Director, and the Director is directed to turn over to the Assessor and Tax Collector a Notice of Lien on each of said properties on which the assessment has not been paid. The Assessor and Tax Collector shall add the amount of said assessment to the next regular bill for taxes levied against the premises upon which said assessment was not paid. Said assessment shall be due and payable at the same time as said property taxes are due and payable, and, if not paid when due and payable, shall bear and interest at the rate of six percent (6%) per annum. (Ord. 652, § 15, 11/26/1968)
