Kan. Stat. § 3-151
The governing body of any such city, or the board of park commissioners or airport authority, with the approval of the governing body of the city by a two-thirds vote of the members thereof, may contract for the acquisition, construction, reconstruction, alteration, repair, improvement, extension or enlargement of such airport and issue and sell revenue bonds in payment of the cost thereof without submitting to a vote of the electors of such municipality such proposal. The governing body of such city, or the board of park commissioners or airport authority, shall before contracting for any such proposed project, cause to be published in the official paper of such city a notice, which shall describe the nature of the proposed acquisition, construction, reconstruction, alteration, repair, improvement, extension or enlargement of such airport, state the total amount of the cost thereof and the amount of bonds to be issued for the payment thereof. If within sixty (60) days after the publication of such notice there shall be filed with the clerk of such municipality a written protest against such proposed project and bond issue, signed by qualified electors of such municipality equal in number to not less than two percent (2%) of the electors of such city who voted at the last preceding general election, the governing body of such municipality shall submit such proposed project and proposed bond issue to the electors of such municipality. A special election for that purpose shall be held not later than sixty (60) days after the filing of such protest, or at a regular city election or general election, which shall occur not less than thirty (30) days nor more than sixty (60) days after the filing of such protest. At least ten (10) days' notice shall be given for such election. If a majority of electors voting on such proposition at such election shall vote in favor thereof, such acquisition, construction, alteration, repair, improvement, extension or enlargement of such airport shall be made and such bonds may be issued to pay the costs thereof.
