Gov. Code, § 53583

(a) Any local agency may issue bonds pursuant to this article or any revenue bond law under which the local agency is otherwise authorized to issue bonds for the purpose of refunding any revenue bonds of the local agency or, if the local agency is a joint powers authority, any revenue bonds of a member local agency, upon authorization by resolution of that member of the joint powers authority.

(b) The proceedings of any local agency authorizing the issuance of any refunding bonds may provide all of the following for those bonds:

(1) The form of the bonds to be issued as serial bonds, term bonds, or installment bonds, or any combination thereof.

(2) The date or dates to be borne by the bonds.

(3) The time or times of maturity of the bonds.

(4) The interest, fixed or variable, to be borne by the bonds.

(5) The time or times that the bonds shall be payable.

(6) The denominations, form, and the registration privileges of the bonds.

(7) The manner of execution of the bonds.

(8) The place or places the bonds are payable.

(9) The terms of redemption.

(10) Any other terms and conditions determined necessary by the local agency.

(c) (1) The refunding bonds may be sold at public or private sale or on a negotiated sale basis and at the prices, above or below par, as the local agency determines.

(2) (A) If the local agency determines to sell the bonds at public sale, the local agency shall advertise the bonds for sale and invite sealed bids on the bonds by publication of a notice once at least 10 days before the date of the public sale in a newspaper of general circulation circulated within the boundaries of each local agency to be aided by the project to be financed by the issuance of the bonds. If one or more satisfactory bids are received pursuant to the notice, the bonds shall be awarded to the highest responsible bidder. If no bids are received or if the local agency determines that the bids received are not satisfactory as to price or responsibility of the bidders, the local agency may reject all bids received, if any, and either readvertise or sell the bonds at private sale or on a negotiated sale basis.

(B) If the local agency determines to sell the bonds at private sale or on a negotiated sale basis, the local agency shall send a written statement, within two weeks after the bonds are sold, to the California Debt Advisory Commission explaining the reasons why the local agency determined to sell the bonds at private sale or on a negotiated sale basis instead of at public sale.
