Whenever the board of county commissioners of any county in this state shall hereafter make any order granting a petition for the construction of a levee, or levees, to promote the public health, convenience and welfare, and to prevent overflow from any natural watercourse partly within or partly without or wholly within any city of the first class, under the provisions of Kan. Stat. Ann. §§ 24-801 to 24-811, inclusive, 24-814 and 24-815, the lands and property embraced within the boundaries of the territory described in the order of the board of county commissioners granting such petition shall be and constitute a drainage district, and with reference thereto the county commissioners shall have power in its discretion, instead of levying the entire special assessment therefor at one time, to 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 in denominations as the board of county commissioners may prescribe, and shall bear interest at a rate not exceeding the maximum rate of interest prescribed by Kan. Stat. Ann. § 10-1009, payable semi-annually.

And whenever the board of commissioners shall determine to issue improvement bonds under the authority of this act, it shall be the duty of said board, after determining the entire cost and expense of constructing such levee, to apportion the same to and between the several tracts of land, railroads and street railways and highways within the boundaries of said district in proportion to the sums reported by the viewers as the basis of benefit to each respectively, and to levy a specific special assessment against each of the same for the amount so apportioned to it, and it shall be the duty of the county clerk, at once, to mail to each owner of any lot or piece of land or other property liable to such special assessment a written or printed notice of such apportionment, and the owner of any such lot or piece of land or other property may redeem this property from such liability by paying the entire amount chargeable against such property at any time within thirty (30) days from said apportionment, and no bonds shall be issued under the provisions of this act until the expiration of said period.
