Cal. Pub. Util. Code § 105251
The district may borrow money in anticipation of the sale of bonds that have been authorized to be issued, but have not been sold and delivered, and may issue negotiable bond anticipation notes therefor and may renew the same from time to time. The maximum maturity of those notes, including the renewals thereof, shall not exceed five years from the date of delivery of the original notes. The 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. The notes shall not be issued in any amount in excess of the aggregate amount of bonds which the district has been authorized to issue, less the amount of any bonds of that 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. The notes and the resolution or resolutions authorizing them may contain any provisions, conditions, or limitations that a resolution of the district authorizing the issuance of bonds may contain.
