Cal. PUC § 30904

The bonds shall bear interest at a rate or rates not exceeding the maximum rate allowed by law, payable semiannually, except that the first interest payable on the bonds or any series thereof may be for any period not exceeding one year as determined by the board. In the resolution or resolutions providing for the issuance of the bonds, the board may also provide for call and redemption of the bonds prior to maturity at the times and prices and upon any other terms as it may specify. However, no bond shall be subject to call or redemption prior to maturity unless it contains a recital to that effect or unless a statement to that effect is printed thereon. The denomination or denominations of the bonds shall be stated in the resolution providing for their issuance, but shall not be less than one thousand dollars ($1,000). The principal of, and interest on, the bonds shall be payable in lawful money of the United States at the office of the treasurer of the district or at any other place or places as may be designated, or at either place or places at the option of the holders of the bonds. The bonds shall be dated, numbered consecutively, signed by the president and treasurer, and countersigned by the secretary, and the official seal of the district shall be attached. The interest coupons of the bonds shall be signed by the treasurer. All the signatures, countersignatures, and seal may be printed, lithographed, or mechanically reproduced, except that one of the signatures or countersignatures on the bonds shall be manually affixed. If any officer whose signature or countersignature appears on bonds or coupons ceases to be that officer before the delivery of the bonds, his or her signature is as effective as if the officer had remained in office.
