# Naperville, Illinois

Naperville (/ˈneɪpərˌvɪl/ NAY-pər-vil) is a city in DuPage and Will counties in the U.S. state of Illinois. It is a southwestern suburb of Chicago located 28 miles (45 km) west of the city on the DuPage River. As of the 2020 census, its population was 149,540, making it the state's fourth-most populous city.
Naperville was founded in 1831 by Joseph Naper. The city was established by the banks of the DuPage River and was originally known as Naper's Settlement. By 1832, over 100 residents lived in Naper's Settlement. In 1839, after DuPage County was split from Cook County, Naperville became the county seat, which it remained until 1868. Beginning in the 1960s, Naperville experienced a significant population increase as a result of Chicago's urban sprawl.
Naperville is home to Moser Tower and Millennium Carillon, one of the world's four largest carillons. It is also home to an extensive parks and forest preserve network, including Centennial Beach. The city has two school districts, 203 and 204. Naperville's largest employer is Edward Hospital with 4,500 employees. Naperville has a train station served by Amtrak and Metra.

## History

Before any settlement, Naperville was home to Native American tribes. In 1641, the first European contact with Native Americans in Illinois was made with members of the Iliniwek tribe. The Iliniwek was the predominant tribe throughout Illinois at the time. They were later forced off the land by the Potawatomi tribe. The Potawatomi inhabited Naperville when the first settlers arrived. There was a major Potawatomi village at the present site of downtown Naperville, reached from Chicago by a trail that became Ogden Avenue. A minor village was near where Bailey Hobson later built his mill in 1834. Bailey Hobson is credited as the first white settler in Naperville; he built a cabin across the DuPage River's West Branch from the mill in 1830, and built his home there in 1835.
In 1831, Joseph Naper arrived at the west bank of the DuPage River with his family and friends to found what would be known as Naper's Settlement. Among those original settlers were Naper's wife, his brother and his wife, his sister and her husband John Murray, and his mother. Their arrival followed a nearly two-month voyage from Ashtabula County, Ohio, in the Naper brothers' schooner, the Telegraph.
By 1832, over 100 settlers had arrived at Naper's Settlement. After the news of the Indian Creek massacre during the Black Hawk War, these settlers were temporarily displaced to Fort Dearborn for protection from an anticipated attack by the Sauk tribe. Fort Payne was built at Naper's Settlement, the settlers returned and the attack never materialized. The Pre-Emption House was constructed in 1834, as the Settlement became a stagecoach stop on the road from Chicago to Galena. The Pre-Emption House was the first hotel in DuPage county. After DuPage County was split from Cook County in 1839, Naper's Settlement became the DuPage county seat. In 1843, the Illinois General assembly passed an act to incorporate the Naperville Cemetery Association. In 1855, Sybil Dunbar came to Naperville as its first recorded black female resident; she died in 1868 and was buried in Naperville Cemetery.
Naper's Settlement was incorporated as the Village of Naperville in 1857, with a population of 2,000. The county seat distinction was lost in 1868 to Wheaton. On August 5, 1873, a train crashed on the CB&Q tracks about 1.5 miles (2.4 km) east of Naperville. Conductor Williams, who was operating a passenger train, was informed of a freight train occupying the line, but for some reason increased his speed, and upon rounding a curve, ran into a freight caboose. A conductor sitting in the caboose and a cattle drover were instantly killed. The passenger train fireman and engineer jumped out of the locomotive just in time to save their lives.
In 1887, Peter Edward Kroehler established the Kroehler Manufacturing Company's factory in Naperville along the Chicago, Burlington & Quincy tracks. In 1890, reincorporation as a city occurred.
After Professor James Nichols donated $10,000, Nichols Library was built and dedicated in 1898. In January 1907, Edward Sanatorium (now Edward Hospital) was opened by Eudora Hull Spalding. It used the "open air" treatment for tuberculosis patients. In 1908, the Chicago YMCA stated that Naperville was too small for its own YMCA building, but Peter Kroehler led a campaign to build one. In January 1910, Kroehler was the mayor of Naperville and its richest resident, but rumors in Naperville relating to a relationship between him and his stenographer caused him to resign as mayor. After his resignation, he retreated to his Binghamton, New York factory. The YMCA was opened on March 26, 1911, and included the first swimming pool in DuPage County. In February 1920, Edward Sanatorium burned to the ground and cost $500,000 to rebuild.
On April 26, 1946, Naperville was the site of a train disaster. Two Chicago, Burlington and Quincy Railroad trains collided "head to tail" on a single track just west of the Loomis Street grade crossing. The accident killed 45 and injured approximately 127 passengers and/or crew members. In the 1950s, the city limits were about six square miles, but by 1960, the city had its single largest year in geographical expansion in Naperville's history with over 1,500 acres annexed.
In 1955, Edward Sanatorium was converted into a general hospital.
A predominantly rural community for most of its existence, Naperville experienced a population explosion beginning in the 1960s and continuing into the 1980s and 1990s. Throughout the 1980s and '90s, the city's population tripled.
In 1996, Naperville was the site of a flood that also affected the majority of northeastern Illinois. Naperville received 14 inches of rain in less than 24 hours, and DuPage County was declared a disaster zone. The estimated damages were over $30 million.
The YMCA in Downtown Naperville was announced to close in May 2020 after 109 years of operation, due to economic difficulties caused by the COVID-19 pandemic.
On June 20, 2021, an EF3 tornado tore through southeast Naperville, uprooting trees, injuring eight people, and damaging 231 homes.

## Geography

According to the 2021 census gazetteer files, Naperville has a total area of 39.68 square miles (102.77 km$^2$), of which 39.10 square miles (101.27 km$^2$) (or 98.52%) is land and 0.59 square miles (1.53 km$^2$) (or 1.48%) is water.
Parts of Naperville drain to the West Branch of the DuPage River in DuPage County. The Forest Preserve District ownership of a large amount of property along the West Branch has minimized development in floodplains and has helped reduce the damage from overbank flooding that has occurred in the county's more developed watersheds. The DuPage River Trail also runs along the DuPage River, which serves bikes and pedestrians. Naperville was primarily flat prairie before its settlement. Its main geographic anomalies are manmade hills, such as the Greene Valley Hill, a former garbage dump.
Naperville has had two major floods, one in 1996 and one in 2013.
Naperville is in six townships and two counties. In DuPage County, the northwest portion is in Winfield Township, the northeast portion in Milton Township, the west-central portion in Naperville Township, and the east-central portion in Lisle Township.
In Will County, the southwest portion is in Wheatland Township, and the southeast portion in DuPage Township. The largest number of Naperville residents live in Lisle Township, followed by Naperville Township.
Naperville's municipal boundaries are cut in noticeably by many places. In the west, Springbrook Prairie, a forest preserve run by The Forest Preserve District of DuPage County, is a major enclave. In the southwest, the Tamarack neighborhood is a major unincorporated enclave. In the north, McDowell Grove Forest Preserve and various office complexes around Diehl Road form a major enclave into the boundary.

On September 22, 1898, the Nichols Library formally opened. Its collection comprised over 700 books. With the population of Naperville growing, the original location was running out of space. In 1983 a referendum was passed to build a new library, and the new Nichols Library opened on March 11, 1986. As the population increased, the need for a new branch was evident. Land was acquired, and the upper floor of the Naper Boulevard Library opened to the public on December 29, 1992.

## Infrastructure
### Health systems

Edward Hospital in Naperville, Illinois, was first established in 1907 as Edward Sanitarium, and became Edward Hospital in 1955. It merged with Elmhurst Hospital in 2013 to create Edward-Elmhurst Health. Edward Hospital is a full-service hospital with 352 private patient rooms. For many years, Edward Hospital and others have tried to introduce a new hospital into Naperville, only to have their request turned down. Thus, Naperville remains the only large Illinois city with only one hospital. Edward Hospital tried to open a hospital in nearby Plainfield to help Naperville citizens with travel times to Edward Hospital.
Duly Health and Care, formerly DuPage Medical Group, has 16 locations in Naperville.
The University of Chicago Medical Center has two Naperville locations providing pediatric and ENT services.

### Transportation
#### Roads

The Ronald Reagan Memorial Tollway (the tolled portion of Interstate 88) passes through northern Naperville. US Route 34 (Ogden Avenue) enters Naperville in the west at Illinois Route 59. A diverging diamond interchange, the first in Northeast Illinois, was completed in 2015 at the junction of Route 59 and Interstate 88.

#### Train service

Naperville's first rail link to Chicago was established in 1864 by the Chicago, Burlington and Quincy Railroad. Naperville now has three tracks belonging to the BNSF Railway that run through the north end of town, with passenger rail service provided by Metra and Amtrak. Amtrak's four daily trains through Naperville are the Illinois Zephyr and Carl Sandburg (both destined for Quincy, Illinois), the California Zephyr (destined for Emeryville, California), and the Southwest Chief (destined for Los Angeles). A third Metra station was planned on the Suburban Transit Access Route ("STAR") at Wolf's Crossing. The project is no longer active since 2012.
In the 1990s, Naperville was one of six communities that competed to receive a prototype personal rapid transit system that the Regional Transit Authority was planning to build. A proposal by Rosemont was instead selected, and such a system was ultimately never built.

#### Bus service

Pace provides rush hour bus service to the Metra stations, and previously, through 2008, had provided for local midday service. Both services have always been operated under contract; First Student, a national transportation management firm, is the current contract operator. In addition, Pace directly operates bus route 530 from Naperville to Aurora (which serves Aurora's Fox Valley Mall) and bus route 714 from Naperville to Wheaton (which serves the College of DuPage), both through its Fox Valley division. Pace also directly operates route 888, a rush hour express route named the "Tri-State Flyer", from Homewood and South Holland to corporate employment sites in the western suburbs, including those in the northern part of Naperville; this route is operated by Pace through its South division. Intercity bus service in Naperville consists of a route from Chicago and Naperville to Davenport, Iowa, and points further west, operated by both Burlington Trailways and Greyhound Lines. The Burlington Trailways buses stop at the Naperville Metra and Amtrak station, downtown on Fourth Avenue; the Greyhound Lines buses stop at the Route 59 Metra station.

#### Airport

The DuPage Airport, a general aviation airport serving private and charter jets, designation DPA, is 14 miles from downtown Naperville. Clow Airport in Bolingbrook is about 1.5 miles from Naperville's southeastern border.
There is also a private airport, the Naper Aero Club field, designation LL10, on the western edge of town. The field is notable as the home of the Lima Lima Flight Team.

### Electricity

Naperville's electric system is owned and operated by the City of Naperville, which obtains electricity through the Illinois Municipal Electric Agency, a nonprofit government entity.
