A Look Back
About This Land: Coralville was built upon the homeland of many Indigenous People. Our community exists on land that was home to the Native American Nations of the Iowa, Meskwaki, and Sauk. The Indigenous People faced violence, oppression, and colonialism. Today, we have a shared responsibility to recognize and honor the history, culture, and contributions of the Indigenous People in Iowa and nationwide.
Mid-1800s: The development of Coralville began after the construction in 1843 of what was then the largest dam in Iowa along the Iowa River, and the mills that used the dam’s power. In the early days, the small settlement was known as "Clarksville."
Namesake: The town was christened "Coralville" in 1866 after Louis Agassiz, a Harvard zoologist, spoke at the University of Iowa about the samples of fossilized coral that he found in the limestone around the mills along the Iowa River. Local merchant Ezekial Clark renamed his mill to "Coral Mills," and the small town became known as Coralville.
1873 to World War II: By the time of its incorporation in 1873, Coralville’s population had grown to almost 300. It boasted a blacksmith shop, wagon shop, meat market, lumberyard, dry good store, and four saloons. The Coralville Schoolhouse was built in 1876 on 5th Street, and Old Town Hall was erected on 2nd Avenue in the late 1880s (it was later moved twice). Both the 1876 Schoolhouse and Old Town Hall still stand today on 5th Street.
By 1900, the mills closed and the Iowa City Electric Company had acquired all the waterpower of the dam. Coralville’s economy was so dependent on the mills that their closing spelled decline for the little town.
Coralville began to grow again in the late 1920s and boomed after World War II. Coralville was an attractive place to live because of its inexpensive housing, lower taxes, and proximity to the University campus.
1940s & 1950s: The population of Coralville grew from 433 in 1940, to 977 in 1950. Automobile travel and tourism became common, and the "Coralville Strip" became well-populated with retail shops, service stations, discount stores, restaurants, and motels.
During the same period, the Coralville Dam was built four miles upstream from the city. Authorized in 1938 by Congress, begun in 1949, and completed in 1958 by the US Corps of Engineers, it has prevented serious flooding except for the exceptional years of 1993 and 2008.
1960s-1980s: By 1960, Coralville’s population had reached 2,357, and tripled that by 1970. Construction of the portion of Interstate 80, which was at the time north of Coralville, began in 1963.
Commercial and housing development continued throughout the second half of the 20th century, along with growth in city services. The former power station, which had been shut down in 1968, reopened in 1972 as a riverside restaurant. Coralville's 4th of July festival, 4thFest, began in 1983.
1990s: By the 1990s, Highway 6, known as "the strip," was ready for a makeover, complete with decorative street lighting and plantings. A city center was developed around the city campus and former post office.
In 1996, work began on Coral Ridge Mall, the state’s second-largest indoor shopping center, at the intersection of Interstate 80 and Highways 6 and 965.
Late 1990s to Present: In the late 1990s, local visionaries began efforts to revitalize an industrial park along the Iowa River and Interstate 80. This launched over 30 years of work with the EPA to transform the area from brownfields into the vibrant community gateway, known today as the Iowa River Landing.
In 2008, Coralville experienced historic flooding. Over 200 businesses and more than 400 households were directly impacted, and the City's infrastructure sustained over $7 million in damages. The City swiftly put together a comprehensive flood mitigation plan with permanent and removable flood walls, earthen berms, raising streets and bridges, storm sewer and stormwater pump station improvements, and raising and fortifying a railroad embankment. By 2018, it had completed permanent mitigation measures to protect low-lying areas surrounding Biscuit Creek, Clear Creek, and the Iowa River to a level of one foot above the 2008 flood levels.
As of the 2020 Census, Coralville’s population reached 22,318. Coralville is one of the top 50 fastest-growing cities in Iowa.

About Our Logo
Designed Specifically for Coralville
The logo for Coralville's 150th anniversary was created to uniquely reflect our rich history and bright future.
- Coral in the upper left corner represents our city's namesake. The town was christened "Coralville" for the fossilized corals found in natural rock exposures along the Iowa River, including where the foundation was dug for mills along the river in the 1800s.
- The wheel in the lower left corner represents Coralville's biking and recreational trails, as well as the river-powered mills of Coralville's early days. It also represents the Mormon pioneers who stayed in Coralville in 1856 and 1857, preparing for a 1,300 mile journey from the Midwest to Utah, towing their belongings in handcarts.
- The tree symbolizes Coralville's many parks and open spaces, and the growth of our community.
- Fireworks in the upper right corner represent our community's festivals and celebrations, including Coralville's 4thFest fireworks.
- The iconic 1876 schoolhouse in the lower right corner, with its native limestone foundation and cast iron star claps, was where generations of children in Coralville went to school; it is on the National Register of Historic Places and still sits on 5th Street.
- The vibrant colors of the logo represent the diversity of our community and Coralville's bright future.
