Changes the law regarding the power of certain cities to annex areas from within two miles of the city's existing boundary to four miles

HB 2218 increases the maximum distance cities can annex unincorporated areas from two miles to four miles from their existing boundaries for specific cities. It applies to cities with 16,000-18,000 residents located in counties with 9,900-11,000 residents and county seats of 600-1,000 residents. The bill also allows cities in third-class counties with a state correctional center within two miles to annex the facility, but this remains limited to the two-mile rule. Annexation still requires property owner petitions, a public hearing, and approval based on municipal service capacity.
