California Code, Health and Safety Code - HSC § 4621

All bonds issued under this chapter shall be issued in the name of the city in which the district has been formed, or in the name of the initiating city, as the case may be, shall be in such form as the governing body may determine, and shall be payable at the time and in the manner determined by the governing body, at a place within the United States, to be fixed by the governing body and designated in the bonds. The maturity date of a bond need not be an anniversary of its date. The governing body may divide the principal amount of any issue of bonds into two or more series and fix different dates for the bonds of each series. The bonds of one series may be made payable at different times from those of any other series. The final maturity date of any issue of bonds, or of any series, shall not exceed 40 years from the date of such bonds, or the date of such series of the bonds. Bonds issued pursuant to this chapter shall not constitute indebtedness within the meaning of Section 29909 or Section 43605 of the Government Code.

The governing body may provide for the call and redemption of any bond prior to maturity at such time or times and at such price or prices and upon such other terms as it may specify, but no bond shall be subject to call or redemption prior to maturity unless a statement to that effect is printed on the bond.
