The unpaid assessments shall be payable in annual installments corresponding in number and proportionate amount to the number of installments and principal amounts of bonds maturing or becoming subject to mandatory prior redemption in each year pursuant to Section 8650.1. An annual proportion of each assessment shall be payable in each fiscal year preceding the date of maturity or mandatory prior redemption date of each of the bonds which have been issued, sufficient to pay the bonds when due. The annual proportion of each assessment coming due in any year, together with the annual interest on the assessment, shall be payable in the same manner and at the same time and in the same installments as the general taxes of the city on real property are payable, and the assessment installments and the annual interest on the assessment shall be payable and become delinquent at the same times and in the same proportionate amounts and, except as provided in subdivision (b), shall bear the same proportionate penalties and interest after delinquency as do the general taxes on real property of the city.

The legislative body may provide, in the resolution of intention to do the work, that a penalty of 2 percent per month of the total amount of the delinquent installment shall be added to the delinquent installment after the close of business on the delinquency date and an additional penalty of 2 percent of the amount of the delinquency shall be added at the beginning of business on the 10th day of each succeeding month until that delinquent installment and all penalties thereon are fully paid. This penalty shall be in lieu of all other penalties assessed by other provisions of law. The treasurer or the designated paying agent shall collect the penalties with, and as a part of, the delinquent installments, or the legislative body may designate another official and another method of collection. All penalties collected shall be deposited in the redemption fund.
