When general district indebtedness payable from annual tax levies to be made in excess of the constitutional and/or statutory tax limitations has been authorized, the district may issue its general obligation bonds in payment thereof.
The bonds shall not have terms in excess of twenty years and shall as nearly as practicable be issued for a period which will not exceed the life of the improvement to be acquired by the issuance of the bonds. The bonds shall be issued and sold in accordance with chapter
39.46 RCW. The election at which the voters are presented with a ballot proposition authorizing both the bond issue and imposition of excess bond retirement levies shall be held as provided in RCW
39.36.050.
Whenever the proposition to issue such 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 and/or statutory tax limitations sufficient to meet the annual or semiannual payments of principal and interest on the bonds upon all taxable property within the district.
