(1) An authority may issue revenue bonds to provide funds to carry out its authorized functions without submitting the matter to the voters of the authority. The authority shall create a special fund or funds for the sole purpose of paying the principal of and interest on the bonds of each such issue, into which fund or funds the authority may obligate itself to pay such amounts of the gross revenue of the high capacity transportation system constructed, acquired, improved, added to, or repaired out of the proceeds of sale of such bonds, as the authority shall determine and may obligate the authority to pay such amounts out of otherwise unpledged revenue that may be derived from the ownership, use, or operation of properties or facilities owned, used, or operated incident to the performance of the authorized function for which such bonds are issued or out of otherwise unpledged fees, tolls, charges, tariffs, fares, rentals, special taxes, or other sources of payment lawfully authorized for such purpose, as the authority shall determine. The principal of, and interest on, such bonds shall be payable only out of such special fund or funds, and the owners of such bonds shall have a lien and charge against the gross revenue of such high capacity transportation system or any other revenue, fees, tolls, charges, tariffs, fares, special taxes, or other authorized sources pledged to the payment of such bonds.

Such revenue bonds and the interest thereon issued against such fund or funds shall be a valid claim of the owners thereof only as against such fund or funds and the revenue pledged therefor, and shall not constitute a general indebtedness of the authority.

(2) Notwithstanding subsection (1) of this section, such bonds may be issued and sold in accordance with chapter 39.46 RCW.
