Chicago and its Topography

Chicago is located in northeastern Illinois at the southwestern tip of Lake Michigan. It sits on a continental divide at the site of the Chicago Portage, connecting the Mississippi River and the Great Lakes watersheds. The city lies beside Lake Michigan, and two rivers — the Chicago River in downtown and the Calumet River in the industrial far South Side — flow entirely or partially through Chicago. The Chicago Sanitary and Ship Canal connects the Chicago River with the Des Plaines River, which runs to the west of the city. Chicago’s history and economy are closely tied to its proximity to Lake Michigan. While the Chicago River historically handled much of the region’s waterborne cargo, today’s huge lake freighters use the city’s Lake Calumet Harbor on the South Side. The lake also provides another positive effect, moderating Chicago’s climate; making waterfront neighborhoods slightly warmer in winter and cooler in summer.

When Chicago was founded in the 1830s, most of the early building began around the mouth of the Chicago River, as can be seen on a map of the city’s original 58 blocks. The overall grade of the city’s central, built-up areas, is relatively consistent with the natural flatness of its overall natural geography, generally exhibiting only slight differentiation otherwise. The average land elevation is 579 ft (176 m) above sea level. The lowest points are along the lake shore at 577 ft (176 m), while the highest point, at 735 ft (224 m), is a landfill located in the Hegewisch community area on the city’s far south side.

Lake Shore Drive runs adjacent to a large portion of Chicago’s lakefront. Parks along the lakeshore include: Lincoln Park, Grant Park, Burnham Park and Jackson Park; 29 public beaches are also found along the shore. Near downtown, landfills extend into the Lake, providing space for the Jardine Water Purification Plant, Navy Pier, Northerly Island, the Museum Campus, Soldier Field and large portions of the McCormick Place Convention Center. Most of the city’s high-rise commercial and residential buildings can be found within a few blocks of the lake.

Chicagoland is an informal name for the Chicago metro area, used primarily by copywriters, advertising agencies, and traffic reporters. There is no precise definition for the term “Chicagoland”, but it generally means the city and its suburbs together. The Chicago Tribune, which coined the term, includes the city of Chicago, the rest of Cook County, eight nearby Illinois counties: Lake, McHenry, DuPage, Kane, Kendall, Grundy, Will and Kankakee, and three counties in Indiana: Lake, Porter, and LaPorte. The Illinois Department of Tourism defines Chicagoland as Cook County without the city of Chicago, and only Lake, DuPage, Kane and Will counties. The Chicagoland Chamber of Commerce defines it as all of Cook and DuPage, Kane, Lake, McHenry and Will counties.

Chicago and its Neighborhoods

Chicago is partitioned into four main sections: Downtown (which contains the Loop), the North Side, the South Side, and the West Side. In the late 1920s, sociologists at the University of Chicago subdivided the city into 77 distinct community areas. The boundaries of these areas are more clearly defined than those of the over 210 neighborhoods throughout the city, allowing for better year-by-year comparisons.

Downtown is the center of Chicago’s cultural, commercial and financial institutions, and home to Grant Park and many of the city’s skyscrapers. Many of the city’s financial institutions are located within a section of downtown called “The Loop”, which is an eight block by five block square of city streets that are encircled by elevated rail lines.

The North Side is the most densely populated residential section of the city and many highrises are located on this side of the city along the lakefront. Lincoln Park is a 1,200-acre (490 ha) park stretching for 5.5 mi (8.9 km) along the waterfront and is also home to the Lincoln Park Zoo. The River North neighborhood features the nation’s largest concentration of contemporary art galleries outside of New York City. As a Polonia center, due to the city having the largest population of Poles of any city in the world outside of Warsaw, Chicago celebrates every Labor Day weekend at the Taste of Polonia Festival in the Jefferson Park area.[30]

The South Side is home to one of the city’s largest parades, the annual African American Bud Billiken Day parade, and the University of Chicago. Parkland stretches along the waterfront of the South Side. Two of the city’s largest parks are also located here: Jackson Park, bordering the waterfront, hosted the World’s Columbian Exposition in 1893 and is the site of the Museum of Science and Industry. Slightly farther west is Washington Park, which is currently being considered as the primary site of the Olympic Stadium for the 2016 Summer Olympics, if Chicago wins the bid. The two parks are connected by a strip of parkland called Midway Plaisance. Also, the U.S. automaker, Ford Motor Company, has an assembly plant located on the South Side.

The West Side holds the Garfield Park Conservatory, one of the largest collections of tropical plants of any U.S. city. Cultural attractions include Humboldt Park’s Puerto Rican Day festival, and the National Museum of Mexican Art in Pilsen. The Near West Side holds the television production company of Harpo Studios.

Chicago and its Transportation Infrastructure
Chicago is a major transportation hub in the United States. It is an important component in global distribution, as it is the third largest inter-modal port in the world after Hong Kong and Singapore. Additionally, it is the only city in North America in which six Class I railroads meet. As of 2002, severe freight train congestion caused trains to take as long to get through the Chicago region as it took to get there from the West Coast of the country (about 2 days). About one-third of the country’s freight trains pass through the city, making it a major national bottleneck. Announced in 2003, the Chicago Region Environmental and Transportation Efficiency (CREATE) initiative is using about $1.5B in private railroad, state, local, and federal funding to improve rail infrastructure in the region to reduce freight rail congestion by about one third. This is also expected to have a positive impact on passenger rail and road congestion, as well as create new greenspace.

Chicago is the largest hub of passenger rail service in the nation. Many Amtrak long distance services originate from Union Station. Such services terminate in New York, Seattle, Portland, New Orleans, San Francisco, Los Angeles, San Antonio, and Washington, D.C. Amtrak also provides a number of short-haul services throughout Illinois and toward nearby Milwaukee, Indianapolis, Saint Louis, and Detroit. An attempt was made in the early 20th century to link Chicago with New York City via the Chicago – New York Electric Air Line Railroad. Parts of this were built, but it was ultimately never completed.

Nine interstate highways run through Chicago and its suburbs. Segments that link to the city center are named after influential politicians, with four of them named after former U.S. Presidents. Traffic reports tend to use the names rather than interstate numbers.

The Regional Transportation Authority (RTA) coordinates the operation of the three service boards: CTA, Metra, and Pace. The Chicago Transit Authority (CTA) handles public transportation in the city of Chicago and a few adjacent suburbs. The CTA operates an extensive network of buses and a rapid transit elevated and subway system known as the ‘L’ (for “elevated”), with lines designated by colors. These rapid transit lines also serve both Midway Airport and O’Hare Airport. The CTA’s rail lines consist of the Red, Blue, Green, Orange, Brown, Purple, Pink, and Yellow lines. Both the Red and Blue lines offer 24 hour service which makes Chicago one of the few cities in the world (and one of only two American cities) to offer rail service every day of the year for 24 hours around the clock. A new subway/elevated line, the Circle Line, is also in the planning stages by the CTA. Metra operates commuter rail service in Chicago and its suburbs. The Metra Electric Line shares the railway with the South Shore Line’s NICTD Northern Indiana Commuter Rail Service, providing commuter service between South Bend and Chicago. Pace provides bus and paratransit service in over 200 surrounding suburbs with some extensions into the city as well. Bicycles are permitted on all CTA and Metra trains during non-rush hours and on all buses 24 hours.

Chicago offers a wide array of bicycle transportation facilities, such as miles of on-street bike lanes, 10,000 bike racks, and a state-of-the-art central bicycle commuter station in Millennium Park. The city has a 100-mile (160 km) on-street bicycle lane network that is maintained by the Chicago Department of Transportation Bike Program and the Chicagoland Bicycle Federation. In addition, trails dedicated to bikes only are built throughout the city.

Chicago is served by Midway International Airport on the south side and O’Hare International Airport, the world’s second busiest airport, on the far northwest side. In 2005, O’Hare was the world’s busiest airport by aircraft movements and the second busiest by total passenger traffic (due to government enforced flight caps).[81] Both O’Hare and Midway are owned and operated by the City of Chicago. Gary/Chicago International Airport, located in nearby Gary, Indiana, serves as the third Chicago area airport. Chicago Rockford International Airport, formerly Greater Rockford Airport, serves as a regional base for United Parcel Service cargo flights, some passenger flights, and occasionally as a reliever to O’Hare, usually in times of bad weather. Chicago is the world headquarters for United Airlines, the world’s second-largest airline by revenue-passenger-kilometers and the city is the second largest hub for American Airlines. Midway airport serves as a major ‘focus city’ for Southwest Airlines, the world’s largest low-cost airline.
