Ann Arbor was founded in 1824, named for wives of the village's founders and the stands of Bur Oak trees. The University of Michigan moved from Detroit to Ann Arbor in 1837, and the city grew at a rapid rate in the early to mid-20th century. During the 1960s and 1970s, the city gained a reputation as a center for left-wing politics. Ann Arbor became a focal point for political activism and anti-Vietnam War movement, as well as various student movements.
Ann Arbor is home to the University of Michigan, one of the foremost research universities in the United States. The university shapes Ann Arbor's economy significantly as it employs about 30,000 workers, including about 12,000 in the 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, and by its graduates.
In about 1774, the Potawatomi founded two villages in the area of what is now Ann Arbor.
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 "Annarbour;" this represents 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 640 acres (260 ha) of land they purchased for $800 from the federal government at $1.25 per acre. The local Ojibwa named the settlement kaw-goosh-kaw-nick, 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 40 acres (16 ha) of undeveloped land and offered it to the state of Michigan as the site of the state capital, but lost the bid to Lansing. In 1837, the property was accepted instead as the site of the University of Michigan, which moved from Detroit.
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. 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 African-Americans. 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 coming from Greece, Italy, Russia, and Poland. 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.
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; many of these remain in effect in modified form. Alongside these liberal and left-wing efforts, a small group of conservative institutions were born in Ann Arbor. These include Word of God (established in 1967), a charismatic inter-denominational movement; and the Thomas More Law Center (established in 1999), a religious-conservative advocacy group.
Following a 1956-vote, the city of East Ann Arbor merged with Ann Arbor to encompass the eastern sections of the city.
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 2008, it was ranked by CNNMoney.com 27th out of 100 "America's best small cities". And in 2010, Forbes listed Ann Arbor as one of the most liveable cities in the United States.
According to the United States Census Bureau, the city has a total area of 28.70 square miles (74.33 km2), of which, 27.83 square miles (72.08 km2) of it is land and 0.87 square miles (2.25 km2) is water, much of which is part of the Huron River. Ann Arbor is about 35 miles (56 km) west of Detroit. Ann Arbor Charter Township adjoins the city's north and east sides. Ann Arbor is situated on the Huron River in a productive agricultural and fruit-growing region. The landscape of Ann Arbor consists of hills and valleys, with the terrain becoming steeper near the Huron River. The elevation ranges from about 750 feet (230 m) along the Huron River to 1,015 feet (309 m) on the city's west side, near the intersection of Maple Road and Pauline Blvd. Generally, the west-central and northwestern parts of the city and U-M's North Campus are the highest parts of the city; the lowest parts are along the Huron River and in the southeast. Ann Arbor Municipal Airport, which is south of the city at 42°13.38′N 83°44.74′W, has an elevation of 839 feet (256 m).
Ann Arbor's "Tree Town" nickname stems from 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. In recent years, the emerald ash borer has destroyed many of the city's approximately 10,500 ash trees. The city contains 157 municipal parks ranging from small neighborhood green spots to large recreation areas. 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. The Nichols Arboretum, owned by the University of Michigan, is a 123-acre (50 ha) 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.
The Kerrytown Shops, Main Street Business District, the State Street Business District, and the South University Business District are commercial areas in downtown Ann Arbor. 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-century 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. Tower Plaza, a 26-story condominium building located between the University of Michigan campus and downtown, is the tallest building in Ann Arbor. 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, and it is further protected by city ordinances and a nonprofit preservation group.
Ann Arbor has a typically Midwestern humid continental climate (Köppen Dfa), which is influenced by the Great Lakes. There are four distinct seasons: winters are the coldest time of year, with average highs around 34 °F (1 °C); however, summers have average highs around 81 °F (27 °C) with slightly more precipitation. Spring and autumn are transitional between the two. The area experiences lake effect weather, primarily in the form of increased cloudiness during late fall and early winter. The monthly daily average temperature in July is 72.6 °F (22.6 °C), while the same figure for January is 24.5 °F (−4.2 °C). Temperatures reach or exceed 90 °F (32 °C) on 10 days, and drop to or below 0 °F (−18 °C) on 4.6 nights. Precipitation tends to be the heaviest during the summer months, but most frequent during winter. Snowfall, which normally occurs from November to April but occasionally starts in October, averages 58 inches (147 cm) per season. The lowest recorded temperature was −23 °F (−31 °C) on February 11, 1885 and the highest recorded temperature was 105 °F (41 °C) on July 24, 1934.
As of the 2010 U.S. Census, there were 113,394 people, 45,634 households, and 21,704 families residing in the city. The population density was 4,270.33 people per square mile (2653.47/km²). There were 49,982 housing units at an average density of 1,748.0 per square mile (675.0/km²), making it less densely populated than inner-ring Detroit suburbs like Oak Park and Ferndale (and than Detroit proper), but more densely populated than outer-ring suburbs like Livonia or Troy.

In 2013, Ann Arbor had the second-largest community of Japanese citizens in the state of Michigan, numbering 1,541; this figure trailed only that of Novi, which had 2,666 Japanese nationals. In addition, as of 2005, Ann Arbor has a small population of Arab Americans, including several students as well as local Lebanese and Palestinians.
In 2000, out of 45,693 households, 23.0% had children under the age of 18 living with them, 37.8% were married couples living together, 7.5% had a female householder with no husband present, and 52.5% were nonfamilies. 35.5% of households were made up of individuals and 6.6% had someone living alone who was 65 years of age or older. The average household size was 2.22 and the average family size was 2.90. The age distribution was 16.8% under 18, 26.8% from 18 to 24, 31.2% from 25 to 44, 17.3% from 45 to 64, and 7.9% were 65 or older. The median age was 28 years. For every 100 females there were 97.7 males; while for every 100 females age 18 and over, there were 96.4 males.
The median income for a household in the city was $46,299, and the median income for a family was $71,293 (these figures had risen to $51,232 and $82,293 respectively as of a 2007 estimate). Males had a median income of $48,880 versus $36,561 for females. The per capita income for the city was $26,419. About 4.6% of families and 16.6% of the population were below the poverty line, including 7.3% of those under age 18 and 5.1% of those age 65 or over.
The University of Michigan shapes Ann Arbor's economy significantly. It employs about 30,000 workers, including about 12,000 in the medical center. Other employers are drawn to the area by the university's research and development money, and by its graduates. High tech, health services and biotechnology are other major components of the city's economy; numerous medical offices, laboratories, and associated companies are located in the city. Automobile manufacturers, such as General Motors and Visteon, also employ residents.
High tech companies have located in the area since the 1930s, when International Radio Corporation introduced the first mass-produced AC/DC radio (the Kadette, in 1931) as well as the first pocket radio (the Kadette Jr., in 1933). The Argus camera company, originally a subsidiary of International Radio, manufactured cameras in Ann Arbor from 1936 to the 1960s. Current firms include Arbor Networks (provider of Internet traffic engineering and security systems), Arbortext (provider of XML-based publishing software), JSTOR (the digital scholarly journal archive), MediaSpan (provider of software and online services for the media industries), Truven Health Analytics, and ProQuest, which includes UMI. Ann Arbor Terminals manufactured a video-display terminal called the Ann Arbor Ambassador during the 1980s. Barracuda Networks, which provides networking, security, and storage products based on network appliances and cloud services, opened an engineering office in Ann Arbor in 2008 on Depot St. and recently announced it will move downtown to occupy the building previously used as the Borders headquarters. Duo Security, a cloud-based access security provider protecting thousands of organizations worldwide through two-factor authentication, is headquartered in Ann Arbor.
Websites and online media companies in or near the city include All Media Guide, the Weather Underground, and Zattoo. 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, which once housed the Michigan Information Technology Center Foundation. The city is also home to the headquarters of Google's AdWords program—the company's primary revenue stream. The recent surge in companies operating in Ann Arbor has led to a decrease in its office and flex space vacancy rates. As of December 31, 2012, the total market vacancy rate for office and flex space is 11.80%, a 1.40% decrease in vacancy from one year previous, and the lowest overall vacancy level since 2003. The office vacancy rate decreased to 10.65% in 2012 from 12.08% in 2011, while the flex vacancy rate decreased slightly more, with a drop from 16.50% to 15.02%.
Pfizer, once the city's second largest employer, operated a large pharmaceutical research facility on the northeast side of Ann Arbor. On January 22, 2007, Pfizer announced it would close operations in Ann Arbor by the end of 2008. The facility was previously operated by Warner-Lambert and, before that, Parke-Davis. In December 2008, the University of Michigan Board of Regents approved the purchase of the facilities, and the university anticipates hiring 2,000 researchers and staff during the next 10 years. The city is the home of other research and engineering centers, including those of Lotus Engineering, General Dynamics and the National Oceanic and Atmospheric Administration (NOAA). 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.
Borders Books, started in Ann Arbor, was opened by brothers Tom and Louis Borders in 1971 with a stock of used books. The Borders chain was based in the city, as was its flagship store until it closed in September 2011. Domino's Pizza's headquarters is near Ann Arbor on Domino's Farms, a 271-acre (110 ha) 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. Zingerman's has grown into a family of companies which offers a variety of products (bake shop, mail order, creamery, coffee) and services (business education). Flint Ink Corp., another Ann Arbor-based company, was the world's largest privately held ink manufacturer until it was acquired by Stuttgart-based XSYS Print Solutions in October 2005. Avfuel, a global supplier of aviation fuels and services, is also headquartered in Ann Arbor. Aastrom Biosciences, a publicly traded company that develops stem cell treatments for cardiovascular diseases, is also headquartered in Ann Arbor.
Many cooperative enterprises were founded in the city; among those that remain are the People's Food Co-op and the Inter-Cooperative Council at the University of Michigan, a student housing cooperative founded in 1937. There are also three cohousing communities—Sunward, Great Oak, and Touchstone—located immediately to the west of the city limits.
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 Ann Arbor Ballet Theater, the Ann Arbor Civic Ballet (established in 1954 as Michigan's first chartered ballet company), The Ark, and Performance Network Theatre. Another unique piece of artistic expression in Ann Arbor is the fairy doors. These small portals are examples of installation art and can be found throughout the downtown area.
The Ann Arbor Hands-On Museum is located in a renovated and expanded historic downtown fire station. Multiple art galleries exist in the city, notably in the downtown area and around the University of Michigan campus. Aside from a large restaurant scene in the Main Street, South State Street, and South University Avenue areas, Ann Arbor ranks first among U.S. cities in the number of booksellers and books sold per capita. The Ann Arbor District Library maintains four branch outlets in addition to its main downtown building. The city is also home to the Gerald R. Ford Presidential Library.
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.
Ann Arbor is a major scene of college sports, most notably at the University of Michigan, a member of the Big Ten Conference. Several well-known college sports facilities exist in the city, including Michigan Stadium, the largest American football stadium in the world. The stadium was completed in 1927 and cost more than $950,000 to build. It has a 109,901 seating capacity after multiple renovations were made. The stadium is colloquially known as "The Big House". 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.
Ann Arbor is represented in the NPSL by semi-pro soccer team AFC Ann Arbor, a club founded in 2014 who call themselves The Mighty Oak.
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", the latter phrase being adapted from Wisconsin Governor Lee Dreyfus's description of Madison, Wisconsin. 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. Ann Arbor has become increasingly gentrified in recent years.
Ann Arbor has a council-manager form of government. The City Council has 11 voting members: the mayor and 10 city council members. Two city council members are elected from each of the city's five wards. The mayor and council serve four-year terms. The mayor and one council member from each ward are elected in Presidential election years, and the other five council members are elected in the alternate even-numbered years. The mayor is elected citywide. 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.
In 1960, Ann Arbor voters approved a $2.3 million bond issue 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.
Ann Arbor is part of Michigan's 12th congressional district, represented in Congress by Representative Debbie Dingell, a Democrat. On the state level, the city is part of the 18th district in the Michigan Senate, represented by Democrat Rebekah Warren. In the Michigan House of Representatives, representation is split between the 55th district (northern Ann Arbor, part of Ann Arbor Township, and other surrounding areas, represented by Democrat Adam Zemke), the 53rd district (most of downtown and the southern half of the city, represented by Democrat Yousef Rabhi) and the 52nd district (southwestern areas outside Ann Arbor proper and western Washtenaw County, represented by Democrat Donna Lasinski).
As the county seat of Washtenaw County, the Washtenaw County Trial Court (22nd Circuit Court) is located in Ann Arbor at the Washtenaw County Courthouse on Main Street. This court has countywide general jurisdiction and has two divisions: the Civil/Criminal (criminal and civil matters) and the Family Division (which includes Juvenile Court, Friend of the Court, and Probate Court sections). Seven judges serve on the court.
Ann Arbor also has a local state district court (15th District Court), which serves only the City of Ann Arbor. In Michigan, the state district courts are limited jurisdiction courts which handle traffic violations, civil cases with claims under $25,000, landlord-tenant matters, and misdemeanor crimes.
The Ann Arbor Federal Building (attached to a post office) on Liberty Street serves as one of the courthouses for the U.S. District Court for the Eastern District of Michigan and Court of Appeals for the Sixth Circuit.
Progressive politics have been particularly strong in municipal government since the 1960s. Voters approved charter amendments that have lessened the penalties for possession of marijuana (1974), and that aim to protect access to abortion in the city should it ever become illegal in the State of Michigan (1990). In 1974, Kathy Kozachenko's victory in an Ann Arbor city-council race made her the country's first openly homosexual candidate to win public office. In 1975, Ann Arbor became the first U.S. city to use instant-runoff voting for a mayoral race. Adopted through a ballot initiative sponsored by the local Human Rights Party, which feared a splintering of the liberal vote, the process was repealed in 1976 after use in only one election. As of May 2016, Democrats hold the mayorship and nine out of the ten council seats. Nationally, Ann Arbor is located in Michigan's 12th congressional district, represented by Democrat Debbie Dingell.
In 2015, Ann Arbor was ranked 11th safest among cities in Michigan with a population of over 50,000. It ranked safer than cities such as Royal Oak, Livonia, Canton and Clinton Township. The level of most crimes in Ann Arbor has fallen significantly in the past 20 years. In 1995 there were 294 aggravated assaults, 132 robberies and 43 rapes while in 2015 there were 128 aggravated assaults, 42 robberies and 58 rapes (under the revised definition).
Ann Arbor's crime rate was below the national average in 2000. The violent crime rate was further below the national average than the property crime rate; the two rates were 48% and 11% lower than the U.S. average, respectively.
Public schools are part of the Ann Arbor Public Schools (AAPS) district. AAPS has one of the country's leading music programs. In September 2008, 16,539 students had been enrolled in the Ann Arbor Public Schools. There were 21 elementary schools, five middle schools (Forsythe, Slauson, Tappan, Scarlett, and Clague) three traditional high schools (Pioneer, Huron, and Skyline), and three alternative high schools (Community High, Stone School, and Roberto Clemente) in the district. The district also operates a K-8 open school program, Ann Arbor Open School, out of the former Mack School. This program is open to all families who live within the district. Ann Arbor Public Schools also operates a preschool and family center, with programs for at-risk infants and children before kindergarten. The district has a preschool center with both free and tuition-based programs for preschoolers in the district.
Ann Arbor is home to several private schools, including the Rudolf Steiner School of Ann Arbor, Clonlara School, Michigan Islamic Academy, and Greenhills School, a prep school. The city is also home to several charter schools such as Central Academy (PreK-12) of the Global Educational Excellence (GEE) charter school company, and Honey Creek Community School.
The University of Michigan dominates the city of Ann Arbor, providing the city with its distinctive college-town character.
Other local colleges and universities include Concordia University Ann Arbor, a Lutheran liberal-arts institution; a campus of the University of Phoenix; and Cleary University, a private business school. Washtenaw Community College is located in neighboring Ann Arbor Township. In 2000, the Ave Maria School of Law, a Roman Catholic law school established by Domino's Pizza founder Tom Monaghan, opened in northeastern Ann Arbor, but the school moved to Ave Maria, Florida in 2009, and the Thomas M. Cooley Law School acquired the former Ave Maria buildings for use as a branch campus.
The Ann Arbor News, owned by the Michigan-based Booth Newspapers chain, is 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, It resumed using its former name in 2013. It 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. Ann Arbor has been said to be the first significant city to lose its only daily paper. The Ann Arbor Chronicle, an online newspaper, covered local news, including meetings of the library board, county commission, and DDA until September 3, 2014.
Current publications in the city include the Ann Arbor Journal (A2 Journal), a weekly community newspaper; the Ann Arbor Observer, a free monthly local magazine; and Current, a free entertainment-focused alt-weekly.

Electrical power and gas are provided by DTE Energy. AT&T Inc. is the primary wired telephone service provider for the area. Cable TV service is primarily provided by Comcast.
The streets in downtown Ann Arbor conform to a grid pattern, though this pattern is less common in the surrounding areas. Major roads branch out from the downtown district like spokes on a wheel to the highways surrounding the city. The city is belted by three freeways: I-94, which runs along the southern and western portion of the city; U.S. Highway 23 (US 23), which primarily runs along the eastern edge of Ann Arbor; and M-14, which runs along the northern edge of the city. Other nearby highways include US 12 (Michigan Ave.), M-17 (Washtenaw Ave.), and M-153 (Ford Rd.).
