Charter townships



Washtenaw County was formed from a portion of Wayne County. It is one of many Michigan counties which has a name not borne by any other county in the United States. As the population increased, townships were formed. Amongst the townships, communities have grown from hamlets into villages and cities. Some of the townships have elected to incorporate as charter townships.


The county government operates the jail, maintains rural roads (through a largely independent road commission), operates the major local courts, keeps files of deeds and mortgages, maintains vital records, administers public health regulations, and participates with the state in the provision of welfare and other social services. The county board of commissioners controls the budget but has only limited authority to make laws or ordinances. In Michigan, most local government functions — police and fire, building and zoning, tax assessment, street maintenance, etc. — are the responsibility of individual cities and townships.


In partnership with private enterprise, the county maintains a wireless network which is currently available to approximately 50% of county residents. This is the Wireless Washtenaw Project. The stated aim of this project is to one day provide wireless access to 100% of all county residents.

Wireless communication

Washtenaw county is in the process of acquiring land for natural preservation. The program started in 2001, was renewed in 2010, and will end in 2021. Eight parcels of land had been purchased by July 2007. These parcels are of special ecological, recreational, and educational benefits. They are preserved in a natural unimproved state and are open to the public during daylight hours.

Washtenaw county operates 10 parks and one recreation center (gymnasium). These parks include one with a water sprinkler area for children to splash through, one park with a substantial water park component, and one golf course. The recreation center has a swimming pool, indoor track, basketball courts, complete set of resistance machines, a weight room, and several multipurpose rooms.

According to the U.S. Census Bureau, the county has a total area of 722 square miles (1,870 km2), of which 706 square miles (1,830 km2) is land and 16 square miles (41 km2) (2.3%) is water.[8]


In 1849, the Michigan State Normal School (now Eastern Michigan University) was established in Washtenaw's oldest settlement, the city of Ypsilanti.

The "frostbitten constitutional convention" was held at Ann Arbor, the county seat, in 1835. Following resolution of the Toledo War (1835-1836), in which Michigan Territory gave up its claim to the Toledo strip in exchange for most of the Upper Peninsula, Michigan became a state on January 26, 1837. The University of Michigan, founded at Detroit in 1817, was then moved by the state to Ann Arbor in 1839 as a consolation for the city not being named the new state capital, as it had hoped. The University subsequently became and remains the largest employer in the county.

Swamps were drained and farms were tiled to lower the water table. The swamp northwest of the I-94 and US-23 intersection, and areas within Waterloo Recreation Area still appear as they did to early settlers. As productive farms became established, the local deer herds grew. In the 1820s and 1830s, the events surrounding the independence of Greece from Turkey inspired construction of Greek Revival buildings, and the names of townships, towns, and children.

Four years after the first platting out of the county, Washtenaw county was established as a separate self-administered county by an act of the Michigan Territorial Legislature, in 1826.[5] It was attached for administrative purposes to Wayne County until {before 1829} when county government was seated. Ingham and other counties were formed from portions of territorial Washtenaw County.

In 1822, the Legislative Council of the Michigan Territory government defined the name and boundaries of the county; however, it was at first administered as a part of Wayne County. The word: Washtenaw is a variant of the Ojibwe word: "Wash-ten-ong," meaning what is now called the "Grand River".[6] At the time of the official naming of the county in 1822, the headwaters of the Grand River fell within the original boundaries of Washtenaw County, which encompassed a much larger area than the current area of the county.[1] In the Ojibwe language, the word "Wash-ten-ong" literally translates as "far away waters", and was then used by the Ojibwe as the name for the Grand River due to the great length of that river.[7] Accordingly, most literally, the definition of the word "Washtenaw" could be said to mean, "far away waters".[1]

The earliest histories mention trade conducted in the area at the Potawatomi Trail and Pontiac Trail crossings of the Huron River by French traders, and later English then American settlers. The first successful settlement was established at the present site of Ypsilanti about 1809 by French traders.[5]
