Kan. Stat. § 24-486
In addition to the powers hereby conferred upon any drainage district incorporated hereunder and set forth in article 4 of chapter 24 of the Kansas Statutes Annotated, and notwithstanding any provisions therein contained to the contrary, the drainage district, acting by and through its board of directors, shall have authority to cause suitable plans to be prepared and drainage work to be executed, drains to be built, necessary lands and easements to be acquired, and all necessary drainage work to be constructed and assessments for benefits to be made, in accordance with law. Such work may be done, assessments levied and bonds issued without the submission of the same to a vote of the electors, and until and unless the total face value of the bonds issued by the drainage district, exclusive of any interest coupons, exceeds the sum of 5% of the assessed valuation of all of the taxable property located within the drainage district, as determined by the last assessment thereof as shown by the records in the office of the county appraiser. Bonds may be issued and special assessments may be levied and spread to redeem the same, with interest, without the submission of same to a vote of the electors of the district. If the total amount of bonds issued by the drainage district equals or exceeds the above-named sum, no bonds shall be issued or assessments made without the submission of the proposition to a vote of the electors of the district as otherwise provided by law. All assessments shall be made as provided by K.S.A. 24-422, and amendments thereto, by the three disinterested assessors appointed by the board of directors from the electors of the county or counties in which the district is located.
