(a) Subject to the provisions of subsection (b), the governing body of any drainage district may issue emergency no-fund warrants of the drainage district to pay the costs and expenses resulting from an emergency within the district. An emergency within the district exists by reason of current injuries to persons or property, or imminent danger thereof, from floods or other injurious action of water in any watercourse within the district. In case of an emergency, the governing body of the district may build new dikes and levees, and repair, expand and strengthen old ones, dig ditches, build jetties, or make any other changes, alterations and additions in existing improvements. The governing body also may build any other new structure or other improvement it deems necessary to solve the problems created by the emergency. The governing body shall levy a tax at the first tax levying period after the issuance to pay the emergency no-fund warrants and interest thereon. The levy shall be in addition to all other levies authorized or limited by law. Emergency no-fund warrants shall be issued, registered, redeemed and bear interest in the manner and in the form prescribed by K.S.A. 79-2940, and amendments thereto, except that such no-fund warrants shall be issued without the approval of the state board of tax appeals and shall not bear the notation required thereby.
