Modifies provisions relating to annexation

This bill modifies Missouri laws to clarify how cities, towns, and villages can annex unincorporated areas by defining specific requirements for what counts as "contiguous and compact." It directly affects local governments and property owners by establishing rules that prevent annexations connected only by narrow strips like railroad lines while allowing connections across major highways or railroads. The legislation also sets new procedures requiring public hearings within a specific timeframe when annexation is requested by property owners or common-interest communities. Additionally, it includes special provisions allowing certain smaller cities in specific counties to annex areas up to two miles from their borders or to voluntarily annex nearby correctional centers.
