Washington Revised Code Title 57. Water-Sewer Districts § 57.20.105. Vote on general indebtedness

The commissioners may submit to the voters of the district at any general or special election, a proposition that the district incur a general indebtedness payable from annual tax levies to be made in excess of the constitutional tax limitation for the construction of any part or all of the improvements described in its general comprehensive plan or plans. Elections shall be held as provided in RCW 39.36.050. The proposition authorizing both the bond issue and imposition of excess bond retirement levies must be adopted by three-fifths of the voters voting thereon, at which election the total number of persons voting on the proposition shall constitute not less than forty percent of the total number of votes cast in the district at the last preceding general election. The bonds shall not be issued to run for a period longer than thirty years from the date of the issue. The bonds shall be issued and sold in accordance with chapter 39.46 RCW.

Whenever the proposition to issue general obligation bonds and impose such excess bond retirement levies has been approved, there shall be levied by the officers or governing body charged with the duty of levying taxes, annual levies in excess of the constitutional tax limitation sufficient to meet the annual or semiannual payments of principal and interest on the bonds upon all taxable property within the district.
