Wash. Rev. Code § 52.26.120
Any fire protection district within the authority may be dissolved by a majority vote of the registered electors of the district at an election conducted by the election officials of the county or counties in which the district is located in accordance with the general election laws of the state. The proceedings for dissolution may be initiated by the adoption of a resolution by the board. The dissolution of the district shall not cancel outstanding obligations of the district or of a local improvement district within the district, and the county legislative authority or authorities of the county or counties in which the district was located may make annual levies against the lands within the district until the obligations of the districts are paid. All powers, duties, and functions of a dissolved fire protection jurisdiction within the authority boundaries, pertaining to providing fire protection services may be transferred, by resolution, to the regional fire protection service authority.
