Monmouth, IL – Now that the State of Illinois has approved a historic district for Monmouth, the town will try to be listed on the National Register of Historic Places. Linda Lee Blaine of the Western Illinois Economic Development Partnership says the attempt is designed to spur downtown redevelopment. The Courthouse Commercial District includes 72 buildings located within two blocks fo the square. Blaine says if the National Park Service lists the district, building owners could be eligible for up to a 20 percent tax credit if they remodel following historic preservation guidelines. Blaine says the National Park Service is expected to announce its decision next month.
