Cal. Wat. Code § 25035.5
Notwithstanding any other provision of this division requiring any election, any district described in Section 20560.1 may issue refunding bonds for the purpose of refunding any or all of the outstanding bonds of the district, even if the principal amount of the refunding bonds is greater than the principal amount of the bonds being refunded, without the necessity of calling and holding an election in the district if the issuance of the refunding bonds results in a reduction in the total remaining interest and principal payments on bonds of the district. In no event shall the proceeds of any refunding bonds issued pursuant to this section be used for purposes other than to refund outstanding bonds of the district or for purposes other than those for which the refunded bonds were authorized.
