Kan. Stat. § 24-430
Whenever the board of directors of any drainage district shall, under authority vested in it by this act, cause any levee to be constructed or other work done, payment for which is to be made by the levy of special assessments, it may in its discretion, instead of levying the entire special assessment therefor at one time, provide for the payment of the same by installments, and issue improvement bonds therefor payable in installments of equal amounts each year, for such number of years as may be deemed advisable. Such improvement bonds shall be issued as provided by law, but no bonds shall be issued under the provisions of this section until the expiration of thirty days after the report of the assessors shall have been confirmed, as provided in K.S.A. 24-422; and during said thirty days any person against whose property any special assessment shall have been levied may pay the same in full and thereby discharge his property from the lien thereof.
