[3] Peosta experienced a 70% increase in population (estimated) from 2000 to 2007, making it the state's 10th fastest-growing city during that period.

The community is home to the 2015 ASA D Northern Nationals Men's Slow Pitch Champions, Kass & Company, a large industrial park, the largest campus of Northeast Iowa Community College, and a handful of new commercial businesses.

However, the city is increasingly becoming a bedroom community, much like nearby Asbury, made up of suburban subdivisions.

[citation needed] Peosta is named after the leader of a local Native American people that once lived in Dubuque County.

Chief Peosta, of the Meskwaki people, was a close friend of Julien Dubuque, one of the first European settlers in the area.

For most of its history, and even as recently as 1990, Peosta was a quiet rural town of approximately 100 people.

[5] The groundwork for later growth was laid in the 1960s, when the new four-lane U.S. Route 20 opened along the city's southern edge, providing quick access to Dubuque.

The city now boasts two elementary schools, its own community center, hotel, church, industrial park and expanding neighborhoods.

The city administrator is Annette Ernst, the city clerk is Marcie Winkelman, and the current mayor is Russell Pfab, and the council members are: Gerry Hess, John Kraft, Justin Lau, Alexis Lundgren and Brian Schatz.

The city council meets at 6 P.M. on the second and fourth Tuesday of the month at the Peosta Community Centre.

[7] According to the United States Census Bureau, the city has a total area of 1.97 square miles (5.10 km2), all land.

The city's manufacturing, warehousing, and shipping companies form the main part of the economy.

Most of the companies in the city are relatively new, which has led to a significant number of commuters driving to Peosta's employers from Dubuque, Asbury, or Dyersville.

Some of the larger employers in the city include: Berry Plastics, First Gear, Mi-T-M, Bodine Electric, and Colony Brands.

Also, Northeast Iowa Community College employs hundreds of people at its Peosta Campus.

For higher education, Peosta benefits from a campus of Northeast Iowa Community College, which includes large nursing, welding, business, and computer programs, among other majors.
