Campton Hills is a village in Kane County, Illinois and is a western suburb of Chicago. The population of the village is 11,131 per the 2010 US Census. The village was established on May 14, 2007, by incorporating 20.3 square miles of Campton and Plato townships, including the unincorporated community of Wasco. The incorporation followed an April 17 referendum in which 55 percent of voters approved incorporation. Several areas on the village's boundaries disconnected within the first year of incorporation, taking advantage of less restrictive requirements imposed by state statute during that period. As of August 2009, the village comprises 17.16 square miles (44.4 km2).
