California Code, Public Resources Code - PRC § 5568

For the purpose of acquiring, constructing, or completing any improvement or improvements authorized by this article, or for the purpose of acquiring any land or other property necessary or useful therefor, the board of directors may incur an indebtedness not to exceed 5 percent of the assessed valuation of the real and personal property situated in the district or in any zone established pursuant to Section 5566 for the purpose of levying a tax to pay all sums coming due to repay the indebtedness. The district may issue bonds for the indebtedness under and in full compliance with the provisions of Article 1 (commencing with Section 43600) of Chapter 4 of Division 4 of Title 4 of the Government Code. The provisions of that chapter, as they may exist from time to time and insofar as they may be applicable, shall govern all district bond issues, and the board of each district is the legislative branch of the district, and authorized to do all acts and things which may be done by the legislative branch of cities, towns, and municipal corporations in the incurring of indebtedness and the issuance and sale of bonds.

Taxes for the payment of the bonds shall be levied and collected in the manner provided in this article.

The bonds issued under this section shall be signed by the president of the board and the treasurer of the district, and countersigned by the secretary. The coupons shall be signed by the treasurer. If any officers whose signatures appear on the bonds or coupons cease to be officers before the delivery of the bonds to the purchaser, those signatures or countersignatures are, nevertheless, valid and sufficient for all purposes, the same as if the officers had remained in office until the delivery of the bonds.
