Cal. Pub. Util. Code § 29234
The district may borrow money in anticipation of the sale of bonds which have been authorized to be issued, but which have not been sold and delivered, and may issue negotiable bond anticipation notes therefor and may renew the same from time to time, but the maximum maturity of any such notes, including the renewals thereof, shall not exceed five years from the date of delivery of such original notes. Such notes may be paid from any moneys of the district available therefor and not otherwise pledged. If not previously otherwise paid the notes shall be paid from the proceeds of the next sale of the bonds of the district in anticipation of which they were issued and if not so paid taxes may be levied for their payment in the same manner as taxes are levied for the payment of general obligation bonds pursuant to Section 29121 until such bonds are issued. Such notes shall not be issued in an amount in excess of the aggregate amount of bonds which the district has been authorized to issue, less the amount of any bonds of such authorized issue previously sold, and also less the amount of other bond anticipation notes therefor issued and then outstanding. The notes shall be issued and sold in the same manner as the bonds. Such notes and the resolution or resolutions authorizing the same may contain any provisions, conditions, or limitations which a resolution of the district authorizing the issuance of bonds may contain.
