Kan. Stat. § 12-1,115
If any special assessments levied by the city in accordance with K.S.A. 12-1617e, 12-1617f or 12-1755, and amendments thereto, remain unpaid for a period of one year or more after their initial levy, the city may collect the amount due in the same manner as a personal debt of the property owner to the city by bringing an action in the district court of the county in which the city is located. Such actions may be maintained, prosecuted, and all proceedings taken, including any award of postjudgment interest in accordance with K.S.A. 16-204, and amendments thereto, to the same effect and extent as for the enforcement of an action for debt. All provisional remedies available in such actions shall be and are hereby made available to the city in the enforcement of the payment of such obligations. In such actions, the city also shall be entitled to recover interest at the rate provided in K.S.A. 79-2004, and amendments thereto, from and after the date a delinquency occurs in the payment of special assessments levied in accordance with K.S.A. 12-1617e, 12-1617f or 12-1755, and amendments thereto. The city may pursue collection both by levying a special assessment and in the manner provided by this section, but only until the full cost and any applicable interest has been paid in full.
