History
The area around La Grange was first settled in the 1830s, when Chicago residents moved out to the west due to the rapid population increase in the city in the decade since its incorporation. The first settler, Robert Leitch, came to the area in 1830, seven years before the City of Chicago was incorporated. La Grange's location, at approximately from the Chicago Loop, is not considered far from the city by today's standards, but at the time, the area was not yet well-connected to any major hubs. The village was officially incorporated on June 11, 1879. It was founded by Franklin Dwight Cossitt, who was born in Granby, Connecticut, and raised in Tennessee, and moved to Chicago in 1862 where he built a wholesale grocery business. In 1870, Cossitt purchased several hundred acres of farmland in Lyons Township, along the Chicago-Dixon Road, known today as Ogden Avenue (U.S. Highway 34). Ogden Avenue, on the site of a defunct Native American trail, was also referred to as the "Old Plank Road". Planks were often stolen by settlers to be used as building material, which made traveling very bumpy. When the Chicago, Burlington & Quincy Railroad came to town, La Grange was a milk stop called Hazel Glen. A few miles to the south, through present-day Willow Springs, the Illinois and Michigan Canal had emerged as a major shipping corridor, connecting Chicago and the Great Lakes with the Illinois and Mississippi rivers. Cossitt set out to build the ideal suburban village – laying out streets, planting trees, donating property for churches and schools, and building homes for sale between 2,000–8,000 US$. He also placed liquor restrictions in the land deeds he sold to prevent the village from becoming a saloon town. When Cossitt began his development, the area was served by a post…
Geography
La Grange is located at (41.807938, −87.873455), about west of Chicago. The village is roughly flat, only deviating from the elevation of 645 feet by at most ten feet. La Grange is surrounded by incorporated places of similar sizes on all sides except to the South West, where the La Grange Highlands are. As of 2020, La Grange has a total area of , all land. Two major railroad tracks run through the village, including the Burlington Northern Santa Fe, and the CSX/Indiana Harbor Belt lines. Some 14,000 years ago, the land under La Grange sat on the western shore of Lake Chicago, a predecessor to Lake Michigan. The prehistoric shoreline today is delineated by Bluff Avenue, a north–south street on the village's east side.
