# Special districts in Illinois

Special districts in Illinois are forms of local government that are responsible for a narrow set of responsibilities, as opposed to counties, townships, and municipal governments which have a wide range of responsibilities. School districts and community college boards are not usually considered special-purpose governments despite their narrow focus on education.
Illinois has the most special districts of any U.S. state. The exact number depends on how one defines a "special district." The United States Census Bureau has determined that Illinois has 3,227 special-purpose governments as of June 30, 2012; the most of any U.S. state. The Office of the Illinois Comptroller, which uses a broader definition that includes special districts without budget autonomy, determined the state has 4,755 as of December 2015.
The various districts may enact ordinances, rules, and regulations to carry out their various duties. Most have police powers to enforce those rules. Special districts have other powers granted to them by relevant laws.

## Criticism and reform efforts

The small units are also criticized for a lack of transparency and their "patchwork nature" making it difficult for local residents to ascertain which entities are responsible for which services.
In 2012, DuPage County performed a review that found a variety of small units of government that provide mosquito abatement, sanitary and street lighting services cost taxpayers $300 million annually. These districts included small entities such as the one square mile Century Hill Street Lighting District whose board members had wanted to dissolve the district, but were unable to.
In response, Tom Cullerton introduced SB 494 as a pilot program to allow for consolidation of these types of government bodies. The bill would allow the DuPage County Board to pass ordinances to dissolve thirteen small units of government after an audit issued by the County Board Chair was completed. The dissolution of a district could to be overturned via referendum by voters in that district. The bill's cosponsors included suburban legislators and it was supported by Republican County Board Chair Dan Cronin. On April 25, the bill was passed unanimously in the Illinois Senate and on May 6, its house counterpart sponsored by Deb Conroy passed the Illinois House of Representatives with 108 yes votes. The bill was signed into law by Pat Quinn in August. Since then, DuPage County has been able to pass an ordinance to dissolve the Fairview Fire Protection District. In 2015, Representative Jack Franks a co-sponsor of SB 494 proposed legislation to give McHenry and Lake counties the same ability to consolidate small, special purpose districts.
In 2015, Bruce Rauner created a 28-member bipartisan Government Consolidation and Unfunded Mandates Task Force chaired by Evelyn Sanguinetti, then the Lieutenant Governor of Illinois with a focus on reducing unfunded mandates and promoting consolidation of special districts.
