Cal. Water Code § 78680.16

Each contract which the department enters into for a loan pursuant to Section 78680.14 shall require the sale of the interests in lands that are acquired with the loan funds if, in the department’s determination, the construction of the project has not commenced within a period of two years from the date of the first disbursement of loan funds under the contract or within any extension of such period that is granted by the department. In that event, the contract shall require that the interests in lands be offered for sale within six months from the expiration of the two-year period, or any extension thereof, and shall require that the proceeds of the sale be applied toward the repayment of the principal amount of the loan and toward the payment of the accrued interest thereon. Any remaining proceeds, after deducting the administrative costs of the public agency identified in connection with the purchase and sale of the interests in lands, shall be repaid to the department.
