Naperville was voted the second-best place to live in the United States by Money magazine in 2006 and it was rated first on the list of best cities for early retirement in 2013 by Kiplinger. As of the 2010 census, the city had a population of 141,853, which was estimated to have increased to 147,112 by July 2015. It is the fifth-largest city in Illinois.
In July 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 Almeda Landon, his brother John with wife Betsy Goff, his sister Amy with husband John Murray, and his mother Sarah. Their arrival followed a nearly two-month voyage across three Great Lakes in the Naper brothers' schooner, the Telegraph. Also on the journey were several families who remained in the settlement that would become Chicago, including that of Dexter Graves who is memorialized in Graceland Cemetery by the well-known Lorado Taft statue "Eternal Silence" (also known as "the Dexter Graves Monument").
By 1832, over one hundred settlers had arrived at Naper's Settlement. Following 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 stage-coach stop on the road from Chicago to Galena. Reconstructions of Fort Payne and the Pre-Emption House stand as part of Naper Settlement outdoor museum village, which was established by the Naperville Heritage Society and the Naperville Park District in 1969 to preserve some of the community's oldest buildings.
In 1855 Sybil Dunbar came to Naperville as its first recorded black female resident; she died in 1868 and was buried in Naperville Cemetery on Washington Street. A commemorative marker honoring her was placed in the cemetery in 2015.
After DuPage County was split from Cook County in 1839, Naper's Settlement became the DuPage county seat, a distinction it held until 1868. Naper's Settlement was incorporated as the Village of Naperville in 1857, at which time it had a population of 2,000. Reincorporation as a city occurred in 1890.
On April 26, 1946, Naperville was the site of one of the worst train disasters in Chicago history. Two Chicago, Burlington and Quincy Railroad trains, the Advance Flyer and the Exposition Flyer, 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. This event is commemorated in a metal inlay map of Naperville on the southeast corner of the Nichols Library's sidewalk area. In 2012, author Chuck Spinner published The Tragedy at the Loomis Street Crossing which details the tragedy and gives the stories of the 45 persons who perished. On April 26, 2014, a memorial entitled Tragedy to Triumph was dedicated at the train station. The sculpture by Paul Kuhn is dedicated not only to the crash victims but also to the rescuers at the site.
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, following the construction of the East-West Tollway (now known as the Ronald Reagan Memorial Tollway) and Interstate 355 (originally known as the North-South Tollway, now the Veterans Memorial Tollway). It has nearly quadrupled in size as the Chicago metropolitan area's urban sprawl brought corporations, jobs, and wealth to the area.
The March 2006 issue of Chicago magazine cites a mid-1970s decision to make and keep all parking in downtown Naperville free to keep downtown Naperville "alive" in the face of competition with Fox Valley Mall in Aurora and the subsequent sprawl of strip shopping malls. Parking meters were taken down, parking in garages built in the 1980s and 1990s is free, and parking is still available on major thoroughfares during non-peak hours.
Naperville marked the 175th anniversary of its 1831 founding in 2006. The anniversary events included celebrations, concerts and a balloon parade.
Geography and climateEdit
According to the 2010 census, Naperville has an area of 39.323 square miles (101.85 km2), of which 38.77 square miles (100.41 km2) (or 98.59%) is land and 0.553 square miles (1.43 km2) (or 1.41%) is water.
Portions of the city of Naperville drain to the West Branch of the DuPage River within DuPage County. Specifically, in the flood of 1996, downtown businesses in the City of Naperville incurred significant damage. Overall, however, Forest Preserve District ownership of a large amount of property along the West Branch has minimized development in flood plains and has helped reduce the damages from overbank flooding that have occurred in the county's more developed watersheds.

The Naperville Public Library has been ranked number one in the United States each year from 1999 through 2010, for cities with populations between 100,000 and 249,999 by Hennen's American Public Library Ratings.
There are three public library locations within the city limits:
- The Nichols Library is in downtown Naperville, at 200 W. Jefferson Street. It opened at this location in March 1986. It is a 63,300 square feet (5,900 m2) structure and is pictured at right. The previous library building still stands on Washington Street, just south of the YMCA building, at Washington and Van Buren.
- The Naper Boulevard Library was dedicated in December 1992 and underwent internal renovations in 2015. It is at 2035 S. Naper Boulevard and is the smallest of the three buildings at 32,000 square feet (3,000 m2)
- The 95th Street Library is near the intersection of 95th Street and Route 59, at 3015 Cedar Glade Drive (just west of Neuqua Valley High School). Opened in September 2003, it is the newest and largest of the three facilities at 73,000 square feet (6,800 m2) and features a modern, curving architectural style.
The Naperville Municipal Band is a nonprofit organization founded in 1859. They perform a summer concert series in Naperville’s Central Park, as well as several other concerts around the City, and are made up of over 90 volunteer musicians.
Moser Tower and Millennium CarillonEdit
In 1999, Naperville was designated a White House Millennium Community, due to the construction of the Moser Tower and Millennium Carillon. The tower is a bell tower just north of Aurora Avenue and at the base of Rotary Hill within the Riverwalk Park complex.
The Carillon is designated as a Grand Carillon, with 72 bells, and is one of only four in the world that span six octaves. It was dedicated in an Independence Day event on June 29, 2000, with a reception attended by over 15,000, and a performance by the Naperville Municipal Band and the Naperville Men's Glee Club and Festival Chorus. The Carillon is both manually and also computer-playable, with most performances done by hand, but with half the bells played by a computer-controlled system at set times during the day. At present, the Carillon is operational and tours are available after concerts. Disputes over funding the completion of the tower were debated before the Naperville City Council during the fall of 2005 (and are still not resolved).[needs update] The tower's design won an award for "Best Custom Solution" from the Precast/Prestressed Concrete Institute (PCI).
Naperville River WalkEdit
Called as the "Crown Jewel" of Naperville[by whom?]. It features 1.75 miles of brick paths, fountains, bridges, meeting and event places, outdoor sculpture and artwork, recreational facilities, and celebratory memorials. The Naperville Riverwalk was created in 1981 as a permanent commemorative to honor Naperville’s 150th anniversary.
The Riverwalk has amenities along its path. To the east lies Fredenhagen Park with its landmark clock tower and Exchange Club Memories Fountain. Midway, the Dandelion Fountain, Paddleboat Quarry and unique bell tower can be found. Further west is historic Centennial Beach with its 6.2 million gallons of water that starts with zero depth and goes as deep as 15 feet. It is classified as a “beach” through the Illinois Department of Health and not as a swimming pool. The water itself is chlorinated, re-circulated and hand-skimmed to remove debris, but it is not filtered like a typical swimming pool. Further west is Centennial Park with its inline skating/skateboarding facility and the Jaycee Playground.

Edward Hospital serves Naperville while Good Samaritan in Downers Grove, Central DuPage in Winfield and two other hospitals in nearby Aurora also serve the city. 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 currently is trying to open a hospital in nearby Plainfield to help Naperville citizens with travel times to Edward Hospital.
The Naperville Park District manages and provides leisure and recreational activities for Naperville and nearby residents. The District was established by referendum in 1966. As of 2007, the Park District manages over 2,400 acres (10 km2) of open space, including over 130 parks and four sports complexes. The Park District also manages two golf courses, Springbrook and Naperbrook. In addition, the Park District is responsible for the Naperville Riverwalk, construction of which began in 1981, marking the 150th anniversary of the first Joseph Naper's settlement. The Park District maintains and beautifies the riverwalk throughout the year with the help of community members. The Naperville Riverwalk is 1.75 miles long and runs along the West Branch of the DuPage River. It is made up of brick paths, fountains, and covered bridges. In addition, the riverwalk features the Dandelion Fountain, the Naperville Century Walk, the Riverwalk Eatery, and the Commander Dan Shanower-Sept. 11 Memorial. The memorial also includes over 140 faces made by local school children symbolizing the casualties of September 11. As of April 2015, a 2.4 acre Water Street District development has started just south of the Naperville Riverwalk between Main and Webster streets. The city of Naperville and Naperville Park District are planning to expand the riverwalk to add an art wall and seating areas. The Water Street project is expected to be completed in the fall of 2016. North Central College with the help of the city of Naperville is planning to construct a park along the riverwalk, but the project has been suspended for the time being. Some of the other facilities managed by the Park District include:

As a typical American suburb, Naperville uses automobiles as its main mode of transportation. The Ronald Reagan Memorial Tollway (the tolled portion of Interstate 88) runs near the north edge of Naperville with 3 exits serving the city at IL 59, Winfield Rd. (in Warrenville), and Naperville Rd. Interstate 55 runs about 5 miles south of the city, through Bolingbrook and Romeoville. People wishing to reach Naperville from I-55 exit at Weber Road and head north.
US Route 34 Ogden Avenue enters Naperville in the west at Illinois Route 59 coming from Oswego and Aurora at an east-northeast/west-southwest angle. At Rickert Drive, US 34 Ogden Ave curves to the north and goes under the BNSF Railroad bridge before turning east at North Aurora Road/Raymond Dr. US 34 Ogden Ave exits the east side of the city at Naper Blvd and continues into Lisle and Downers Grove.
Illinois Route 59 travels north and south coming into town from Plainfield on the south (just south of 111th Street) and Warrenville on the north (at I-88). Route 59 is also the west border with Aurora from US 34 Ogden Ave to the BNSF Railroad bridge. A Diverging Diamond Interchange, the first in Northeast Illinois, was completed in 2015 at the junction of IL Route 59 and Interstate 88.
Main east-west streets include: 111th St. (Hassert Blvd.), 95th St., 87th St., Aurora Ave., North Aurora Rd., Diehl Rd., Rickert Dr., Royce Rd., Bailey Rd., Hobson Rd., and Chicago Ave.
Main north-south streets include: Raymond Dr., Book Rd., River Rd., West St., Naperville-Plainfield Rd., Modaff Rd., Washington St., Naper Blvd.(Naperville Rd.), and Wehrli Rd.
From 75th Street south Naperville numbered east-west streets roughly follow the same grid layout as the City of Chicago. In other words, if 75th Street continued east past its terminus at Illinois Route 83, in Willowbrook, it would eventually be the same 75th Street as found in Chicago city limits. However, the older part of Naperville has a second numerical grid, starting downtown at Main and Benton, with 4th and 5th Avenues just north of the BNSF tracks, and continuing through 15th Avenue. The difference is that the numbers in the older system go up from downtown, traveling south to north, and the other grid's numbers go up as you travel north to south. There is also a geographical-based naming system, with West Street and North Street defining the older boundaries of the city. Along with these are streets named after the city they lead to, i.e., Naper/Plainfield Road heads towards Plainfield, while Aurora Avenue leads to Aurora and Chicago Avenue to Chicago (it becomes Maple Ave. in neighboring Lisle before becoming 55th Street in Downers Grove).
The first rail link to Chicago dates to 1864, established by the Chicago, Burlington and Quincy Railroad. Naperville currently 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 is planned on the Suburban Transit Access Route ("STAR") at Wolf's Crossing.
Pace provides rush hour feeder 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 Westfield 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.
