Cal. Wat. Code § 71814
A district may borrow money in anticipation of the sale of, but not in excess of the principal amount of, authorized bonds of the district which have not yet been sold and delivered, and for that purpose may issue and sell negotiable bond anticipation notes, and may refund such notes from time to time, but the maximum maturity of any such notes, as originally issued or as refunded, shall not exceed five years from the date of the original notes. The notes shall be sold in such manner as the board may determine, and such notes and the resolution providing for the issuance of such notes may contain any provision, condition or limitation which a bond, or any resolution or ordinance providing for the issuance of bonds, may contain. The interest on bond anticipation notes shall be payable at the time or times provided in such notes and may be represented by interest coupons attached to the notes and shall be payable from the same funds from which the interest on bonds of the district are payable. The principal of such notes may be paid from any moneys of the district available for such purpose. If such notes, or any portion thereof, have not been previously paid, they shall be paid from the proceeds of the next sale of bonds in anticipation of which the notes were issued. The resolution providing for the issuance of bond anticipation notes may contain a provision that, if for any reason bonds of the district are not sold in time to provide funds to pay any unpaid note, and, if other funds of the district are not available for such payment, taxes shall be levied upon the taxable property in the district for such payment in the same manner provided for the payment of bonds in such amount each year for such period of years as may be set forth in such resolution. To the extent bond anticipation notes are paid from a tax levy, authorized bonds in a corresponding amount shall be canceled and not issued thereafter. When bonds of the district are issued and any portion of the proceeds of the sale are to be used to pay bond anticipation notes, such bonds shall mature not later than the maximum permissible years for such bonds under Section 71951 from the date of such notes as originally issued.
