Any industrial district incorporated pursuant to Kan. Stat. Ann. § 19-3801 et seq., and amendments thereto, may be enlarged by the extension of its boundaries to include additional contiguous land of any size which is of the character and location described in Kan. Stat. Ann. § 19-3802, and amendments thereto, upon the petition of the owner or owners of such additional contiguous land, which petition shall be addressed in writing to the board of county commissioners of the county in which such industrial district was organized. The petition shall contain the following: (1) A metes and bounds description of the territory proposed to be added to such industrial district; (2) a statement that all of the privately owned land will be exclusively used for industrial establishments and special facilities to serve industries in an industrial community for the location of plants, factories or warehouses to manufacture, warehouse or distribute the products of agriculture or industries, and that no residential use is presently being made of the land and none will be made as long as the industrial district is in existence and the land is included in it; (3) a prayer that all land described in the petition be added to such industrial district.

Upon the filing of such petition and subject to the provisions of Kan. Stat. Ann. § 19-270, the board of county commissioners shall forthwith fix a time and place for the hearing of such petition and cause the county clerk to give notice thereof by one publication in a newspaper published and of general circulation in the county at least 15 days before the day fixed for the hearing. At the time of the hearing, it shall be the duty of the board of county commissioners first to ascertain and determine whether the required notice has been published, and, if so, to hear all persons in favor or opposed to granting the prayer of the petition and all evidence with respect as to whether or not such petition contains the proper number of signers prescribed by this act and whether the statements in the petition are true. If upon such hearing it shall be found and determined that such petition is sufficient under the requirements of this act and that the granting of such petition has been recommended by the governing body of an incorporated city when such recommendation is required under the provisions of Kan. Stat. Ann. § 19-3801, and amendments thereto, then such board of county commissioners may make a finding and decision approving the application, and if such application is approved, shall declare the territory described in the petition to be added to and to become a part of the industrial district to which the owner of the territory sought to be added, and thenceforth the territory and the owners and lessees of the property therein shall be a part of the industrial district. The order of the board of county commissioners shall recite in haec verba the statements as to the restrictions on use of the lands added to the industrial district which are contained in the petition, and all declarations, determinations, findings, decisions and orders of such board of county commissioners so entered of record shall have the same effect as in the case of orders approving original petitions for incorporation of such industrial districts. A copy of the order of the board of county commissioners adding such additional contiguous land to an already established industrial district, thus enlarging the industrial district, shall be filed for record with the register of deeds of the county in which such industrial district is located, and a copy thereof shall also be filed in the office of the secretary of state of the state of Kansas.
