The supervisors may authorize the issuance of general obligation bonds to finance any flood control improvement or stormwater control improvement and provide for the retirement of the bonds with ad valorem property tax levies. The general obligation bonds may be issued and the bond retirement levies imposed only when the voters of the flood control zone district approve a ballot proposition authorizing both the bond issuance and imposition of the excess bond retirement levies pursuant to Article VIII, section 6 and Article VII, section 2(b) of the state Constitution and RCW 84.52.056. Elections shall be held as provided in RCW 39.36.050. The bonds shall be issued on behalf of the zone or participating zones and be approved by the voters of the zone or participating zones when the improvement has by the resolution, provided in RCW 86.15.110, been found to be of benefit to a zone or participating zones. The bonds may not exceed an amount, together with any outstanding general obligation indebtedness, equal to three-fourths of one percent of the value of taxable property within the zone or participating zones, as the term “value of the taxable property” is defined in RCW 39.36.015. The bonds shall be issued and sold in accordance with chapter 39.46 RCW.
