Part 5 (commencing with

Section 42200) of this division, (2) an assessment to finance the project or the contract has been levied and assessed and remains unpaid in whole or in part, and (3) in the judgment of the board it is for the best interest of the district or the landowners therein to issue bonds for the purpose of obtaining money to pay the costs of the project, all or any part of the outstanding principal of direct assessment warrants heretofore or hereafter issued pursuant to

Section for said project, or charges pursuant to the contract, the board may, by a resolution adopted by a two-thirds vote of its members, authorize the issuance of bonds in an amount not exceeding the amount of the assessment remaining unpaid, without calling or holding any special election pursuant to
