Subject to the provisions of Kan. Stat. Ann. § 19-270, the board of county commissioners of any county which has been designated as an “urban area” under the provisions of section 17 of article 2 of the constitution of the state of Kansas, by resolution, may provide for the consolidation of fire districts and other areas located within such county or parts thereof. Such consolidation may be of fire districts which have governing bodies appointed by the board of county commissioners, may include areas not now within a fire district, and may include areas in a township which makes a tax levy for fire protection purposes but may not include area in an incorporated city furnishing fire protection to the residents of its city, without the consent of such city. In addition, at such time as there is filed with the board of county commissioners of any such county a petition signed by not less than 10% of the qualified electors residing within each of the two or more of the areas mentioned above and proposed for consolidation, the board shall order an election to be called and held within the areas proposed to be consolidated within 90 days after the filing of such petition in the manner provided for the calling and holding of elections under the general bond law. If a majority of the electors voting at such election shall approve the consolidation of such areas the board of county commissioners shall by resolution provide for the consolidation of such areas and define the boundaries of the area as consolidated. Any such consolidation shall be made prior to June 1 of any year to take effect on January 1 of the succeeding year.
