Blood & Biohazard Cleanup Near Hidden Valley Kildeer, IL

Kildeer is a village in southwestern Lake County, Illinois, and a suburb of Chicago that has limited development to custom homes on large lots and worked to preserve its natural features and open space.

The Kildeer area was largely rural, made up of farms and undeveloped land, until after World War II, when it began to attract people who wanted a relatively rural life within commuting distance of Chicago.

On March 22, 1958, residents held a referendum and voted to incorporate the Village of Kildeer with a population of just 153, making it the 32nd municipality in Lake County, with the polling place in the home of Dorothea Huszagh.

Kildeer's incorporation was challenged in court by developer Brickman, who wanted small-lot zoning for a large planned development, but on June 9, 1960, the Illinois Supreme Court found in favor of Kildeer and the village survived.

Kildeer grew from just 173 people in 1960 to 1,609 in 1980, 3,460 in 2000, and 4,091 at the 2020 census.

Kildeer has about 1,499 households according to CMAP's 2024 snapshot, with an average household size of about 2.9 people and an owner-occupancy rate of about 98.7 percent, among the highest in the Chicago region.

According to the 2021 census gazetteer files, Kildeer has a total area of 4.43 square miles, of which about 4.5 percent is water.

Most Kildeer elementary students are served by Kildeer Countryside School District 96, and Kildeer homes feed into Adlai E. Stevenson High School in Lincolnshire, one of Illinois' most highly regarded public high schools.

The 242-acre Heron Creek Forest Preserve, with wetlands and gravel nature trails for hiking and biking, is a major natural feature in the Kildeer area.

Quentin Road through Kildeer was realigned in 1951, removing four right-angle turns, and its entire length was paved in 1952 as Lake County prepared for suburban growth.
