CA Gov't Code Section 25214.5

(a)

The board of supervisors may appropriate up to two million dollars ($2,000,000) from any available funds of the county to a revolving fund to be used by county service areas for the acquisition or improvement of real or personal property, environmental studies, fiscal analyses, engineering services, supplies, or any other lawful expenses. The revolving fund shall be reimbursed within 10 years from the date of the disbursement at a rate of interest, if any, that the board of supervisors shall determine, provided that the interest rate shall not exceed the rate of interest that the county earns on its temporarily idle funds.

(b)

Notwithstanding subdivision (a), if the board of supervisors finds that the reimbursement of the revolving fund may result in an economic or fiscal hardship to the property owners or residents of the county service area, the board of supervisors may, by a four-fifths vote, waive the reimbursement in whole or in part.
