Cal. Gov. Code § 54130
A loan provided for in Sections 54126 and 54129 shall not be made if it would provide for an indebtedness or liability contrary to the provisions of Section 18 of Article XI of the Constitution unless, at an election called by the governing body of the local agency two-thirds of the qualified electors of the local agency voting thereat have authorized the governing body of the local agency to accept, expend, and repay the amount of the loan under this article. Such election shall be held in accordance with provisions of law for the incurring of bonded indebtedness by the local agency, as near as the same may be applicable. Except as may be prohibited by this section, a loan as provided for in Sections 54126 and 54129 may be made to a local agency and the local agency may accept such a loan, notwithstanding any other provision of law limiting or prohibiting the creation of any indebtedness on the part of the local agency.
