Sts. & Hy. Code, § 6468.1

An annual proportion of the aggregate principal sum of bonds issued pursuant to the provisions of this chapter shall be payable on the second day of June of every fiscal year beginning with the fiscal year next following the date of the bonds. The bonds shall bear interest at a rate not in excess of 7 percent per annum from the 31st day after recording the assessment in the office of the superintendent of streets of the entity issuing the bonds, or from their date if the work was done under the Municipal Improvement Act of 1913, on all sums unpaid, until the whole of the principal sum and interest are paid.

Interest shall be payable semiannually by coupon, on the second day of December and June, respectively, of each fiscal year a principal payment accrues. If no bonds are to be issued in the assessment district proceedings other than bonds to represent unpaid assessments against publicly owned property, the bonds shall bear such date as may be determined by the legislative body conducting the proceedings, and shall bear interest from their date. The bonds will continue to bear interest after maturity at the rate stated; provided, they are presented at maturity and payment thereof is refused upon the sole ground that there is not sufficient moneys in said redemption fund with which to pay same. If they are not presented at maturity, interest thereon will run until maturity.
