Wash. Rev. Code § 67.30.030
Any revenue bonds to be issued by any county or city pursuant to the provisions of this chapter, shall be authorized and issued in the manner prescribed by the laws of this state for the issuance and authorization of bonds thereof for public purposes generally: PROVIDED, That the bonds shall not be issued for a period beyond the life of the improvement to be acquired by the use of the bonds.
The bonding authority authorized for the purposes of this chapter shall be limited to the issuance of revenue bonds payable from a special fund or funds created solely from revenues derived from the facility. The owners and holders of such bonds shall have a lien and charge against the gross revenue of the facility. Such revenue bonds and the interest thereon against such fund or funds shall be a valid claim of the holders thereof only as against such fund or funds and the revenue pledged therefor, and shall not constitute a general indebtedness of the municipality. The governing authority of any county or city may by ordinance take such action as may be necessary and incidental to the issuance of such bonds and the retirement thereof. The provisions of chapter 36.67 RCW not inconsistent with this chapter shall apply to the issuance and retirement of any such revenue bonds.
