Genesee County ( / ˈ dʒ ɛ n ə s i / JEN -ə-see ) is a county in the U.S. state of Michigan. According to the 2020 Census, the population was 406,211, and it was estimated to be 401,093 in 2025. This makes Genesee County the fifth-most populous county in Michigan and the most populous in Mid-Michigan. The county seat and largest city is Flint, which is the birthplace of General Motors. Genesee County includes 33 cities, townships, and villages. It is considered part of Mid-Michigan.

The county was named after Genesee County, New York, which comes from the Seneca word Gen-nis'-hee-yo, meaning "Beautiful Valley." Genesee County is part of the Flint, MI Metropolitan statistical area. A major attraction for visitors is Crossroads Village, a living history village located north of Flint.

Genesee County is known for the discovery of a fossil from an ancient whale called Balaenoptera Lacepede. The fossil was found in Thetford Township during mining activities and is estimated to be 11,000 years old.

History

Genesee County was established on March 28, 1835, from land taken from Lapeer, Shiawassee, and Saginaw Counties. The county used Oakland County for legal matters. At the time, only Grand Blanc Township was organized. It was created in 1833 and included areas that are now part of Fenton, Mundy, Flint, Mount Morris, Genesee, Burton, Atlas, and Davison townships. (Atlas and Davison areas were then in Lapeer County.) Flint Township was formed on March 2, 1836, splitting from Grand Blanc. It included areas of Burton, Genesee, and Mount Morris, as well as parts of present-day Clayton, Montrose, Flushing, Thetford, and Vienna. On April 4, 1836, the county was fully organized. Argentine Township was created on July 26, 1836, and included areas that took Fenton away from Grand Blanc and covered the current Argentine area west of Fenton.

In the organizing act of March 11, 1837, two townships, Mundy and Vienna, were formed in the county. Mundy had an additional area to the west. Vienna included the northern tier of three areas in the county, taking two from Flint Township. With this act, just one week after Michigan became a state, the county had 5 township governments.

Genesee, Fenton, and Flushing Townships were formed on March 6, 1838. Genesee and Flushing split from Flint Township. Fenton split from Argentine Township. Genesee included half the survey area to the west. Flushing included the other half of that area (township 8 North range 6 East), while the full area further west (township 8 North range 5 East) and parts of township 7 North range 5 and 6 East were also included. This made Flint Township consist of one and a half survey areas.

In 1839, the Michigan Legislature created Kearsley Township from parts of Flint and Genesee Townships. On March 7, 1843, the legislature dissolved Kearsley, returning the areas to Flint and Genesee. This left Flint Township with about one and a half survey areas.

Two new townships, Thetford and Gaines, were formed on March 9, 1842. Thetford was the easternmost area split from Vienna. Gaines was formed from the western area of Mundy Township.

Genesee County expanded on March 9, 1843, by adding a column of townships from Lapeer County. These included Forest, Richfield, Davison, and Atlas.

On March 25, 1846, two more townships, Clayton and Pewanagawink, were formed. Clayton split the southernmost area from Flushing Township. Pewanagawink took the westernmost area from Vienna and was renamed Montrose in 1848.

Mount Morris Township was created on February 12, 1855, from a single survey area. Its two halves were taken from Flushing and Genesee Townships. Flint Township was divided into three parts when the City of Flint was formed. The remaining area was split into two: the western part became Garland Township (a name later changed back to Flint in 1856), and the eastern part became Burton Township.

In 1950, plans for the Genesee Recreation Area were added to Flint’s master plan. The plan was shared with the Charles Stewart Mott Foundation in 1964, and the foundation supported it. In 1968, the county started its park system by buying vacant land with funds from the Mott Foundation, requiring the formation of a parks commission.

Flint Community Junior College became a county-wide institution after a referendum and millage proposal passed in 1969. It was renamed Genesee Community College on July 5, 1970. In 1973, it was renamed Charles Stewart Mott Community College after C.S. Mott’s death.

In October 2009, County Commissioners asked County Corporate Counsel to discuss merging the County Prosecuting Attorney’s Office with the County Counsel’s Office. By December 2011, County Counsel Ward Chapman planned to retire, raising the possibility of a merger again. On August 9, 2016, the two offices were merged.

In June 2010, the Emergency Management & Homeland Security Department was merged into the Sheriff’s Department. The department director’s position was reduced to a manager role, and a programming coordinator position was eliminated. In July 2010, the County Board voted to merge the clerk and register of deeds offices, effective January 1, 2013.

On October 26, 2010, Genesee County became a founding member of the Karegnondi Water Authority, with Board of Commissioners Chair Jamie W. Curtis representing the county on the Authority Board.

On May 30, 2012, it was reported that Genesee County had 45 confirmed tornadoes since 1950, including the 1953 Flint–Beecher tornado, more than any other county in Michigan during that time.

Geography

According to the United States Census Bureau, the county has a total area of 649.587 square miles (1,682.42 km²), of which 636.944 square miles (1,649.68 km²) is land and 12.643 square miles (32.75 km²) (1.95%) is water. It is the 33rd largest county in Michigan by total area.

Most of the land in the county is very flat, but the southern end has hills and many lakes.

The county is mostly drained by the Flint River, which is used to create Mott Lake and the Holloway Reservoir in the northeast corner of the county. The southeast corner and southern end are drained by the Shiawassee River.

Government and politics

Genesee County is an area where Democrats usually win elections. Since 1932, the county has voted for a Republican candidate only five times. However, since 2016, the county has become more supportive of Republican candidates. In recent elections, Democrats have won by less than 10 points each time, and in 2024, they won by less than 5 points. The last time the county voted for a Republican was during the 1984 reelection of Ronald Reagan.

The county government manages the jail, repairs rural roads, operates local courts, keeps records of property ownership and mortgages, maintains important documents like birth and marriage certificates, enforces public health rules, and helps provide welfare and other social services with the state. The county board of commissioners controls the budget but has limited power to create laws or rules. In Michigan, most local government duties, such as police and fire services, building rules, taxes, and road maintenance, are handled by individual cities and townships.

The Genesee County Road Commission, a separate part of the county government, is led by a five-member group. Road Commissioners are chosen by the County Board of Commissioners, and daily operations are managed by a manager-director.

Except for the City of Flint, Genesee County is under the authority of the 67th District Court of Michigan. District Courts have limited authority as defined by state law. The 67th District Court operates in seven divisions, each with one judge, except for the Central Court Division, which handles jury and felony cases.

Genesee County is one of the founding members of the Karegnondi Water Authority. The "outcounty" area (all parts except Flint) receives library services from the Genesee District Library. The county’s equivalent for schools is the Genesee Intermediate School District, which includes school districts mainly located in Genesee County. Charles Stewart Mott Community College is the local community college that serves the same area as the GISD.

• The Flint Area Narcotics Group is an anti-drug unit in Genesee County led by the Michigan State Police. It includes 17 local members, some of whom share police officers and resources with the group.
• The Genesee Auto-Theft Investigation Network (GAIN) is an anti-auto theft task force led by the Genesee County Sheriff’s Department and includes members from local government.

Recreation

The county's park system is managed by a Parks and Recreation Commission. The director is chosen by the county board of commissioners, who are advised by the parks commission. The commission president is Joe Krapohl, and Barry June is the acting director.

In 1968, the county started its park system by buying vacant land using money from the Charles Stewart Mott Foundation. A requirement of this purchase was the formation of a parks commission.

In January 2018, Genesee County Parks & Recreation bought land near Kearsley Creek for $700,000 from the Poulos family, who own the White Horse Tavern in Flint. This purchase was supported by a grant from the Michigan Natural Resources Trust Fund. The new Atlas County Park opened on April 29, 2018.

The county's park system includes 11,500 acres across the following locations:

• Buell Lake Park, Thetford Township: fishing, picnic areas, playgrounds, ball diamonds, rentable pavilions, snowmobile areas, and a radio-controlled model airplane field.
• Davison Roadside Park, Burton: picnic areas and a beginner sledding hill.
• Flushing County Park, Flushing Township: picnic pavilions, ball diamonds, playgrounds, tennis courts, and cross-country ski trails.
• Holloway Reservoir Regional Park, Richfield and Oregon townships: 5,500 acres, canoe launches, walleye pike boat launches, Buttercup Beach, Elba Equestrian Complex, Hogback Hills, snowmobile areas, sledding/tobogganing, and Wolverine Campground.
• Linden County Park, Fenton Township: picnic pavilions, playgrounds, ball diamonds, snowmobile areas, intermediate sledding, toboggan hills, walking trails, and Clover Beach on Byram Lake.
• Richfield County Park, Richfield Township: ball diamonds, bicycle-motocross tracks, canoe-launching sites, cross-country ski trails, picnic pavilions, playgrounds, snowmobile areas, tennis courts, and walking trails.
• Goldenrod Disc Golf Course, Richfield Township: an 18-basket disc golf course.
• Genesee Recreation Area on Mott Lake: Bluebell Beach and Splash Pad.
• For-Mar Nature Preserve and Arboretum, Burton.
• Atlas County Park, Hegel Road in Atlas Township.
• Crossroads Village and Huckleberry Railroad.
