77.2 JURISDICTION PROFILE The following is a summary of key information about the jurisdiction and its history: • Date of Incorporation—January 25, 1902 • Current Population—52,104 as of the 2011 Census Estimate • Population Growth—It is expected the population of Oak Park will remain steady if not experience minimal growth. • Location and Description—The Village of Oak Park occupies 4.5 square miles on the western border of Chicago, approximately 9 miles from Lake Michigan. It is the 29th largest community in Illinois by population. The Village has easy access to Chicago via the Interstate 90, the Blue and Green L lines, Metra and public transportation. • Brief History—In 1837, Joseph Kettlestrings purchased 172 acres (70 ha) of land just west of Chicago. By 1850, the Galena and Chicago Union Railroad was constructed as far as Elgin, Illinois, and passed through what would later become Oak Park. In the 1850s the land on which Oak Park sits was part of the new Chicago suburb of Cicero. The population of the area boomed during the 1870s, with Chicago residents resettling in Cicero following the Great Chicago Fire of 1871. The Village of Oak Park was formally established in 1902, disengaging from Cicero following a referendum. Oak Park has a history of alcohol prohibition. When the village was incorporated, no alcohol was allowed to be sold within its village limits. This law was relaxed in 1973, when restaurants and hotels were allowed to serve alcohol, and was further loosened in 2002, when select grocery stores received governmental permission to sell packaged liquor. Oak Park attracts architecture buffs and others to view the many Frank Lloyd Wright designed homes found in the village. The largest collection of Wright-designed residential properties in the world is in Oak Park.[5] Other attractions include Ernest Hemingway’s birthplace home and his boyhood home, the Ernest Hemingway Museum, the three Oak Park homes of Tarzan creator Edgar Rice Burroughs, Wright’s Unity Temple, Pleasant Home, the Oak Park-River Forest Historical Society, and the Seward Gunderson Historic District. Oak Park is home to Oak Park and River Forest High School, which is also the public high school for the bordering village of River Forest. A comprehensive college preparatory school,

77-1 Cook County Multi-Jurisdictional Hazard Mitigation Plan; Volume 2: Planning Partner Annexes

Oak Park-River Forest High School has a long history of turning out alumni who have made major or notable contributions to their field of endeavor. Among these are Pulitzer Prize- winning author Ernest Hemingway, football Hall-of-Famer George Trafton, McDonald’s founder Ray Kroc, city planner Walter Burley Griffin, comedian Kathy Griffin, basketball player Iman Shumpert, and the voice of iconic cartoon character Homer Simpson, Dan Castellaneta. • Climate—A humid continental climate is a climatic region typified by large seasonal temperature differences, with warm to hot (and often humid) summers and cold (sometimes severely cold) winters and is commonly found throughout the American Midwest. • Governing Body Format—The village government includes an elected president and an elected village board which hires a village manager to conduct the day-to-day affairs of the administration. Oak Park also has five additional governments which levy real estate taxes. These include the Oak Park Township, the high school district (which also levies from adjacent River Forest), the elementary school district, the library district, and the park district.
