Ann Arbor, MI

Ann Arbor is a city in Washtenaw County, Michigan, United States, and its county seat. The 2020 census recorded its population to be 123,851, making it the fifth-most populous city in Michigan. Located on the Huron River, Ann Arbor is the principal city of its metropolitan area, which encompasses all of Washtenaw County and had 372,258 residents in 2020. Ann Arbor is included in the Detroit–Warren–Ann Arbor combined statistical area and the Great Lakes megalopolis.

Ann Arbor was founded in 1824 by John Allen and Elisha Rumsey. It was named after the wives of the village's founders, both named Ann, and the stands of bur oak trees they found at the site of the town. The University of Michigan was established in Ann Arbor in 1837, and the city's population grew at a rapid rate in the early to mid-20th century.

A college town, Ann Arbor is home to the University of Michigan, which significantly shapes the city's economy, employing about 30,000 workers which includes about 12,000 in its medical center. The city's economy is also centered on high technology, with several companies drawn to the area by the university's research and development infrastructure. The city has been a center for progressive politics as well as several social and religious movements.

History

Before founding as Ann Arbor

The region was once inhabited by several Native American tribes, the most prominent being the Anishinaabe people of the Three Fires: the Odawa, Ojibwe, and Potawatomi. The Potawatomi founded two villages in the area of what is now Ann Arbor in about 1774. Other tribes that inhabited the area included the Meskwaki, Wyandots, and Sauk. These peoples established several trails that converged on present-day Ann Arbor. The land that included Washtenaw County was ceded to the U.S. by the Odawa, Ojibwe, Potawatomi, and Wyandot in the Treaty of Detroit of 1807.

19th century

Ann Arbor was founded in 1824 by land speculators John Allen and Elisha Walker Rumsey. On May 25, 1824, the town plat was registered with Wayne County as the Village of Annarbour, the earliest known use of the town's name. Allen and Rumsey decided to name it for their wives, both named Ann, and for the stands of bur oak in the of land they purchased for $800 () from the federal government at $1.25 per acre.Marwil, pp. 1–2 The local Ojibwa named the settlement , after the sound of Allen's sawmill.

Ann Arbor became the seat of Washtenaw County in 1827 and was incorporated as a village in 1833. The Ann Arbor Land Company, a group of speculators, set aside of undeveloped land and offered it to the state of Michigan as the site of the state capitol, but lost the bid to Lansing. In 1837, the property was accepted instead as the site of the University of Michigan.

Since the university's establishment in the city in 1837, the histories of the University of Michigan and Ann Arbor have been closely linked. The town became a regional transportation hub in 1839 with the arrival of the Michigan Central Railroad, and a north–south railway connecting Ann Arbor to Toledo and other markets to the south was established in 1878.Marwil, p. 49 Throughout the 1840s and the 1850s settlers continued to come to Ann Arbor. While the earlier settlers were primarily of British ancestry, the newer settlers also consisted of Germans, Irish, and Black people. In 1851, Ann Arbor was chartered as a city, though the city showed a drop in population during the Depression of 1873. It was not until the early 1880s that Ann Arbor again saw robust growth, with new immigrants from Greece, Italy, Russia, and Poland.

20th century

Ann Arbor saw increased growth in manufacturing, particularly in milling. Ann Arbor's Jewish community also grew after the turn of the 20th century, and its first and oldest synagogue, Beth Israel Congregation, was established in 1916.

Following a 1956 vote, the city of East Ann Arbor merged with Ann Arbor to encompass the eastern sections of the city.

In 1960, Ann Arbor voters approved a $2.3 million bond issue (equivalent to $ million in ) to build the current city hall, which was designed by architect Alden B. Dow. The City Hall opened in 1963. In 1995, the building was renamed the Guy C. Larcom Jr. Municipal Building in honor of the longtime city administrator who championed the building's construction.

During the 1960s and 1970s, the city gained a reputation as an important center for liberal politics. Ann Arbor also became a locus for left-wing activism and anti-Vietnam War movement, as well as the student movement. The first major meetings of the national left-wing campus group Students for a Democratic Society took place in Ann Arbor in 1960; in 1965, the city was home to the first U.S. teach-in against the Vietnam War. During the ensuing 15 years, many countercultural and New Left enterprises sprang up and developed large constituencies within the city. These influences washed into municipal politics during the early and mid-1970s when three members of the Human Rights Party (HRP) won city council seats on the strength of the student vote. During their time on the council, HRP representatives fought for measures including pioneering antidiscrimination ordinances, measures decriminalizing marijuana possession, and a rent-control ordinance.

Two religious-conservative institutions were created in Ann Arbor; the Word of God (established in 1967), a charismatic inter-denominational movement; and the Thomas More Law Center (established in 1999). Since 1998, Ann Arbor is also the home office of the Anthroposophical Society in the United States, an organization dedicated to supporting the community of those interested in the inner path of schooling known as anthroposophy, developed by Rudolf Steiner..

21st century

In the past several decades, Ann Arbor has grappled with the effects of sharply rising land values, gentrification, and urban sprawl stretching into outlying countryside. On November 4, 2003, voters approved a greenbelt plan under which the city government bought development rights on agricultural parcels of land adjacent to Ann Arbor to preserve them from sprawling development. Since then, a vociferous local debate has hinged on how and whether to accommodate and guide development within city limits. Ann Arbor consistently ranks in the "top places to live" lists published by various mainstream media outlets every year.

In 2016, the city changed mayoral terms from two years to four. Until 2017, City Council held annual elections in which half of the seats (one from each ward) were elected to 2-year terms. These elections were staggered, with each ward having one of its seats up for election in odd years and its other seat up for election in even years. Beginning in 2018 the city council has had staggered elections to 4-year terms in even years. This means that half of the members (one from each ward) are elected in presidential election years, while the other half are elected in mid-term election years. To facilitate this change in scheduling, the 2017 election elected members to terms that lasted 3-years.

In 2020, partly as a response to the COVID-19 pandemic, the city government opened several downtown streets to pedestrians, limiting their use by motor vehicles to emergency vehicles during summertime weekends. In addition to providing a large pedestrian mall, these changes allow restaurants to use more of the sidewalks and part of the street for outdoor seating. These changes were popular enough that in 2021 the city council extended the dates from March to November, continuing the schedule of cordoning off cars from Thursday evening until Monday morning.

Geography

Ann Arbor is located along the Huron River, which flows southeast through the city on its way to Lake Erie. It is the central core of the Ann Arbor, MI Metropolitan Statistical Area, which consists of the whole of Washtenaw County, but is also a part of the Metro Detroit Combined Statistical Area designated by the U.S. Census Bureau. While it borders only Townships, the built-up nature of the sections of Pittsfield and Ypsilanti townships between Ann Arbor and the city of Ypsilanti make the two effectively a single urban area.

Landscape

The landscape of Ann Arbor consists of hills and valleys, with the terrain becoming steeper near the Huron River. The elevation ranges from about along the Huron River to on the city's west side, near the intersection of Maple Road and Pauline Blvd. Ann Arbor Municipal Airport, which is south of the city at , has an elevation of . Ann Arbor is nicknamed "Tree Town", both due to its name and to the dense forestation of its parks and residential areas. The city contains more than 50,000 trees along its streets and an equal number in parks. Into the early 2000s, the emerald ash borer has destroyed many of the city's approximately 10,500 ash trees.

The city contains over 160 municipal parks ranging from small neighborhood green spots to large recreation areas such as Buhr Park. Several large city parks and a university park border sections of the Huron River. Fuller Recreation Area, near the University Hospital complex, contains sports fields, pedestrian and bike paths, and swimming pools. Opened in the summer of 2014, the city-funded Ann Arbor Skatepark is a skatepark located within Veterans Memorial Park. The city is also home to the Washtenaw County-owned County Farm Park. The Nichols Arboretum, owned by the University of Michigan, is a arboretum that contains hundreds of plant and tree species. It is on the city's east side, near the university's Central Campus. Located across the Huron River just beyond the university's North Campus is the university's Matthaei Botanical Gardens, which contains 300 acres of gardens and a large tropical conservatory. Several other green spaces around Ann Arbor are privately owned or owned by government agencies such as Ann Arbor Public Schools.

Cityscape

The cityscape of Ann Arbor is heavily influenced by the University of Michigan, with 22% of downtown and 9.4% of the total land owned by the university. The downtown Central Campus contains some of the oldest extant structures in the city—including the President's House, built in 1840—and separates the South University District from the other three downtown commercial districts. These other three districts, Kerrytown, State Street, and Main Street are contiguous near the northwestern corner of the university.

Major landmarks in downtown Ann Arbor include the Michigan Theater, The Diag, and Tower Plaza, a 26-story condominium building that is the city's tallest building. Downtown is also home to several Fairy Doors and other public art installations.

Three commercial areas south of downtown include the areas near I-94 and Ann Arbor-Saline Road, Briarwood Mall, and the South Industrial area. Other commercial areas include the Arborland/Washtenaw Avenue and Packard Road merchants on the east side, the Plymouth Road area in the northeast, and the Westgate/West Stadium areas on the west side. Downtown contains a mix of 19th- and early-20th-century structures and modern-style buildings, as well as a farmers' market in the Kerrytown district. The city's commercial districts are composed mostly of two- to four-story structures, although downtown and the area near Briarwood Mall contain a small number of high-rise buildings.

Ann Arbor's residential neighborhoods contain architectural styles ranging from classic 19th- and early 20th-century designs to ranch-style houses. Among these homes are a number of kit houses built in the early 20th century. Contemporary-style houses are farther from the downtown district. Surrounding the University of Michigan campus are houses and apartment complexes occupied primarily by student renters. The 19th-century buildings and streetscape of the Old West Side neighborhood have been preserved virtually intact; in 1972, the district was listed on the National Register of Historic Places (NRHP), and it is further protected by city ordinances and a nonprofit preservation group.

Ann Arbor is the home to Internet2 and the Merit Network, a not-for-profit research and education computer network. Both are located in the South State Commons 2 building on South State Street. The city is also home to a secondary office of Google's AdWords program—the company's primary revenue stream. Ann Arbor is home to more than twenty video game and XR studios of varying sizes. The city plays host to a regional chapter of the International Game Developers Association (IGDA) which hosts monthly meetups, presentations, and educational events.

The city is the home of many research and engineering centers, including the Great Lakes Environmental Research Laboratory that is operated by NOAA and the Michigan Tech Research Institute. Other research centers sited in the city are the United States Environmental Protection Agency's National Vehicle and Fuel Emissions Laboratory and the Toyota Technical Center. The city is also home to National Sanitation Foundation International ( NSF International), the nonprofit non-governmental organization that develops generally accepted standards for a variety of public health related industries and subject areas.

Non-high tech companies in Ann Arbor include Domino's Pizza, headquartered on Domino's Farms, a Frank Lloyd Wright-inspired complex just northeast of the city. Another Ann Arbor-based company is Zingerman's Delicatessen, which serves sandwiches and has developed businesses under a variety of brand names. Avfuel, a global supplier of aviation fuels and services, is headquartered in Ann Arbor as is Pinkerton, a detective and private security firm.

There are also three cohousing communities— Sunward, Great Oak, and Touchstone—located immediately to the west of the city limits.

Culture

Several performing arts groups and facilities are on the University of Michigan's campus, as are museums dedicated to art, archaeology, and natural history and sciences. Founded in 1879, the University Musical Society is an independent performing arts organization that presents over 60 events each year, bringing international artists in music, dance, and theater. Since 2001 Shakespeare in the Arb has presented one play by Shakespeare each June, in a large park near downtown. Regional and local performing arts groups not associated with the university include the Ann Arbor Civic Theatre, the Arbor Opera Theater, the Ann Arbor Symphony Orchestra, The Ark, and Performance Network Theatre.

Ford Presidential Library, Ann Arbor ranks first among U.S. cities in the number of booksellers and books sold per capita.

Several annual events—many of them centered on performing and visual arts—draw visitors to Ann Arbor. One such event is the Ann Arbor Art Fairs, a set of four concurrent juried fairs held on downtown streets. Scheduled on Thursday through Sunday of the third week of July, the fairs draw upward of half a million visitors. Another is the Ann Arbor Film Festival, held during the third week of March, which receives more than 2,500 submissions annually from more than 40 countries and serves as one of a handful of Academy Award–qualifying festivals in the United States.

Ann Arbor has a long history of openness to marijuana, given Ann Arbor's decriminalization of cannabis, the large number of medical marijuana dispensaries in the city (one dispensary, called People's Co-op, was directly across the street from Michigan Stadium until zoning forced it to move one mile to the west), the large number of pro-marijuana residents, and the annual Hash Bash: an event that is held on the first Saturday of April. Until (at least) the successful passage of Michigan's medical marijuana law, the event had arguably strayed from its initial intent, although for years, a number of attendees have received serious legal responses due to marijuana use on University of Michigan property, which does not fall under the city's progressive and compassionate ticketing program.

A person from Ann Arbor is called an "Ann Arborite", and many long-time residents call themselves "townies". The city itself is often called "A²" ("A-squared") or "A2" ("A two") or "AA", "The Deuce" (mainly by Chicagoans), and "Tree Town". With tongue-in-cheek reference to the city's liberal political leanings, some occasionally refer to Ann Arbor as "The People's Republic of Ann Arbor" or "25 square miles surrounded by reality." In '' A Prairie Home Companion'' broadcast from Ann Arbor, Garrison Keillor described Ann Arbor as "a city where people discuss socialism, but only in the fanciest restaurants." Ann Arbor sometimes appears on citation indexes as an author, instead of a location, often with the academic degree ''MI'', a misunderstanding of the abbreviation for Michigan.

Sports

Ann Arbor is a major center for college sports, most notably at the University of Michigan. Several well-known college sports facilities exist in the city, including Michigan Stadium, the largest American football stadium and the third-largest stadium of any kind in the world with a capacity of 107,601. The stadium is colloquially known as "The Big House" due to its status as the largest American football stadium. Crisler Center and Yost Ice Arena play host to the school's basketball (both men's and women's) and ice hockey teams, respectively. Concordia University, a member of the NAIA, also fields sports teams.

The mayor is the presiding officer of the city council and has the power to appoint all council committee members as well as board and commission members, with the approval of the city council. The current mayor of Ann Arbor is Christopher Taylor, a Democrat who was elected as mayor in 2014. Day-to-day city operations are managed by a city administrator chosen by the city council. While Democrats, hold the mayorship and all ten council seats, Ann Arbor has two major political factions. A major source of this local divide is differences in views on the city's growth.

'' The Ann Arbor News'', owned by the Michigan-based Booth Newspapers chain, was the major newspaper serving Ann Arbor and the rest of Washtenaw County. The newspaper ended its 174-year daily print run in 2009 due to economic difficulties, and began producing two printed editions a week under the name AnnArbor.com. Ann Arbor has been said to be the first significant city to lose its only daily paper. The publication resumed using its former name in 2013, and also produces a daily digital edition named MLive.com. Another Ann Arbor-based publication that has ceased production was the ''Ann Arbor Paper'', a free monthly. The ''Ann Arbor Chronicle'', an online newspaper, covered local news, including meetings of the library board, county commission, and DDA until September 3, 2014.

A plume of the industrial solvent dioxane is migrating under the city from the contaminated Gelman Sciences, Inc. property on the westside of Ann Arbor. the average measured concentration was found to be 201.19 ppb, with the maximum being 6.000 ppm. While the United States Environmental Protection Agency does not impose a federal limit on the level of the contaminant allowed in drinking water, the World Health Organization suggests a limit of 35 ppb. The Gelman plume is a potential threat to one of the City of Ann Arbor's drinking water sources, the Huron River, which flows through downtown Ann Arbor.

Transportation

The streets in downtown Ann Arbor conform to a grid pattern, though this pattern is less common in the surrounding areas.
