Gov. Code, § 53840

It is hereby declared the intention of the Legislature by the enactment of this article to provide an alternative procedure under which short term loans may be procured by those counties in which the board of supervisors has declared it to be county policy to make advances of current operating requirements to subsidiary political subdivisions required by law to deposit their funds in the county treasury as such advances are authorized by the provisions of Section 25 of Article XIII of the State Constitution. In any such county the board of supervisors, upon recommendation of the county treasurer with the approval of the county auditor, may borrow on July 1st or thereafter such amounts as may be required to meet current obligations payable by the county treasury, pending collection of the revenue provided for the year in progress. Amounts so borrowed shall be evidenced by notes signed by the chairman of the board of supervisors, the county auditor and the county treasurer, and the liability created thereby shall be secured by a lien on all revenue to accrue to the county treasury from any source during the year then in progress.
