(2) The money in any special trust fund created by an ordinance authorizing an issue of revenue bonds shall be used solely for the purposes provided therefor by the ordinance.

(3) The ordinance may obligate the port, and the port shall have power to fix, levy and collect such rates, rentals, fees and other charges for the use and services of all or any of its facilities, which revenues may be pledged to the payment of the principal of and interest on and premium, if any, of the revenue bonds or any of them and if so pledged shall be sufficient to produce revenues, along with other lawfully available funds, adequate to pay the costs of the operation, maintenance and repair of any or all port properties; to pay or provide for the payment of the principal of and interest on, and premium, if any, of such revenue bonds or any of them, including any reserves for such payment; and to produce such additional amount of revenues therefrom as the port may covenant with the holders of such revenue bonds.

(4) The ordinance may provide that in the event the money in a special trust fund is insufficient to pay the revenue bonds to be paid out of the fund, such revenue bonds shall be payable out of any part or all of other nonpledged revenues of the port. Whenever all bonds and expenses thereof have been paid so that no charge remains upon such special fund, the board may, by ordinance, transfer any balance remaining in such fund to its general fund, discharge the trustee, if any, and dissolve the special fund. Any trustee authorized to administer the fund, may, subject to approval of the board, invest and reinvest moneys in the special fund in any security or securities in which the State of Oregon may by law invest.

(5) If the board fails to set aside and pay revenues into a special trust fund as required by the ordinance authorizing the issuance and sale of the bonds secured by the fund, a holder of any of such bonds may bring suit against the port to compel compliance with the provisions of the ordinance in the circuit court of the county in which the port has its principal office.
