(1) If decision shall be rendered in favor of the improvement, the board shall enter an order establishing the boundaries of the improvement district and shall adopt plans for the proposed improvement and determine the number of annual installments not exceeding fifty in which the cost of the improvement shall be paid. The cost of the improvement shall be provided for by the issuance of local improvement district bonds of the district from time to time, therefor, either directly for the payment of the labor and material or for the securing of funds for such purpose, or by the irrigation district entering into a contract with the United States or the state of Washington, or both, to repay the cost of the improvement. The bonds shall bear interest at a rate or rates determined by the board, payable semiannually, and shall state upon their face that they are issued as bonds of the irrigation district; that all lands within the local improvement district shall be liable to assessment for the principal and interest of the local improvement district bonds. The bonds may be in such denominations as the board of directors may in its discretion determine, except that bonds other than bond number one of any issue shall be in a denomination that is a multiple of one thousand dollars. Such bonds may be in any form, including bearer bonds or registered bonds as provided in RCW 39.46.030.

(2) No election shall be necessary to authorize the issuance of such local improvement bonds or the entering into of such a contract.

(3) The proceeds from the sale of such bonds shall be deposited with the treasurer of the district, who shall place them in a special fund designated "Construction fund of local improvement district number . . . . . ."

(4) Whenever such improvement district has been organized, the board may enlarge the boundaries of the improvement district to include other lands which can be served or will be benefited by the proposed improvement upon petition of the owners thereof and the consent of the United States or the state of Washington, or both, in the event the irrigation district has contracted with the United States or the state of Washington, or both, to repay the cost of the improvement: PROVIDED, That at such time the lands so included shall pay their equitable proportion upon the basis of benefits of the improvement theretofore made by the local improvement district and shall be liable for the indebtedness of the local improvement district in the same proportion and same manner and subject to assessment as if the lands had been incorporated in the improvement district at the beginning of its organization.

(5) Notwithstanding this section, such bonds may be issued and sold in accordance with chapter 39.46 RCW.
