California Code, Public Utilities Code - PUC § 22553.5

(a) The board of directors may, from time to time, cause to be sold or leased property of the district which in its opinion is not needed for the district's affairs.

(b) Such sales, at the discretion of the board of directors, may be on time, provided at least 20 percent of the total consideration be paid in cash at the time of the transaction and the remainder thereto be paid within 10 years and evidenced by a promissory note payable to the order of the district bearing interest at the rate of at least 5 percent per annum secured by a first mortgage, first deed of trust, or other prior encumbrance upon the property being sold.

(c) Property may be leased for any purpose and to any party whenever the board of directors finds that such lease does not interfere with use of such property for the purposes of the district or with the operations of the district. All rents and other consideration received by the district shall be paid into its general fund for the use of the district.
