CCS/SS/SCS/HB 2818 - This act modifies provisions regarding annexation by municipalities. This act specifies that for any city, town, or village in St. Charles County, the term "contiguous and compact" shall include a situation whereby the unincorporated proposed to be annexed is contiguous to the annexing city, town, or village by at least eighteen percent of the length of the perimeter of the area proposed for annexation. This act specifies that for any city, town, or village in Jefferson County, the term "contiguous and compact" shall include a situation whereby the unincorporated proposed to be annexed is contiguous to the annexing city, town, or village by at least twenty-five percent of the length of the perimeter of the area proposed for annexation. No such city, town, or village shall annex an unincorporated area contiguous to any unincorporated area annexed by the city, town, or village within the last twenty-four months. This act provides that the city of St. Joseph may annex the airport owned by the city regardless of whether the boundaries of the airport are contiguous and compact to the existing city boundaries. Currently, property owners within an unincorporated area can petition a contiguous and compact city, town, or village within certain counties to annex such unincorporated area. This act repeals this provision. This act contains a severability clause. This act is similar to SB 1342 (2026), HCS/HB 2300 (2026), and HB 631 (2025). TRISTAN BENSON, JR.
