H.A. White General Store and House is a historic building located in North Liberty, Iowa, United States. The central portion of the two-story frame building was completed in 1876. At least three additions were built onto the original in subsequent years. It housed the commercial businesses and residence of H.A. White and his family. It was the only commercial enterprise in North Liberty between 1876 and 1889. White served as the local postmaster from 1877 through 1888, and the building housed the post office in those years. Dr. James Polk Von Stein boarded here c. 1879 to 1891 and had his office here as well. After 1903 the building was used only as a residence, and became a rental property by the 1980s. It was listed on the National Register of Historic Places in 1984. The building is presently used once again for commercial purposes.

The Old State Quarry State Preserve, also known as the North Bend Quarries, Capitol Quarry, Old Capitol Quarry, and the State Quarry, is a historic site located northeast of North Liberty, Iowa, United States. The quarry, originally known as North Bend Quarries, began operations in 1842. It provided limestone for numerous buildings and structures in Iowa City and elsewhere in the state. The list includes the Old Capital (1842), the foundations for Old Brick Church (1856) and the present Iowa State Capitol (1886) in Des Moines. The exact date that the quarry closed is not known, but because there is no evidence of mechanized techniques to remove stone, it is assumed it closed around the turn of the 20th century. There are, however, hand tool marks in the remaining stone. From 1874 to 1911 Samuel Calvin, professor of natural history at the State University of Iowa, used the quarry for both research and instruction in geology and paleontology. The limestone here is made up largely of cemented fragments of brachiopods that lived in a shallow tropical sea that covered this area during the Devonian period. There is also evidence of fish teeth and plates in the lower parts of the channel sequence. The preserve is the type locality for “State Quarry Limestone,” determined by Calvin, and only found in Johnson County, Iowa. The quarry became a historical state preserve in 1969, and it was listed on the National Register of Historic Places in 1998.

The Samuel and Emma A. Ranshaw House is a historic building in North Liberty, Iowa, United States. At the time this house was built in 1908, North Liberty was a small and prosperous farming community. The Ranshaws engaged Iowa City architect-builder Bernard Wickham to design and construct this transitional Free Classic subtype of the Queen Anne style. It is characterized by simple classical decorative details that were becoming popular in the early 20th-century, as opposed to the more elaborate elements of the Late Victorian style. It was a typical house that Wickham was building in this area. The 10-acre (4.0 ha) farmstead on which it was built was surrounded by farm fields just to the west of the town. Suburban development now surrounds the house on its 2-acre (0.81 ha) lot. In addition to the house, a concrete sidewalk and cistern cap with inlaid glass marbles that are set in geometric and floral patterns is included in the nomination. They were listed on the National Register of Historic Places in 2012.

The Iowa Medical and Classification Center (IMCC) is a medium security correctional facility located in the Johnson County community Oakdale in Coralville, Iowa. It currently houses about 900 inmates. The main role of the IMCC is to serve as a reception and classification center for adults being sent to prison. Inmates here are assigned to one of the various prisons in Iowa. For this purpose, the center has a medium security general population unit. IMCC is also the home of the Iowa Forensic Psychiatric Hospital which holds up to 28 patients while being evaluated for mental competency. IMCC also provides medical, educational, and social services to other Iowa prisons. It holds a medium security general population of about 300 Incarcerated Individuals, who work to maintain the facility. In February 2007 a portion of the perimeter fence surrounding the center was damaged in an ice storm. After making temporary plans, officials have proposed replacing all the perimeter fences at the facility - the proposal is currently being studied by the Iowa Legislature.In early May 2020, James McKinney the facility's warden since 2015 suddenly resigned. Newspaper reports indicated that an investigation showed proper safeguards against COVID-19 were not being enforced. His replacement and the current warden of the IMCC is Mike Heinricy.

Oakdale was an unincorporated rural residential village established in 1908 by the State of Iowa as a statewide treatment center for tuberculosis (TB) in rural Johnson County, located about five miles northwest of central Iowa City and now a part of Coralville, immediately adjacent to the community of North Liberty.The site was chosen for its remoteness, its location along a railroad, and its proximity to University of Iowa Hospitals and Clinics in Iowa City. As a partially self-sustaining community, Oakdale included a depot on the Cedar Rapids and Iowa City Railway (CRandIC) line, power plant, several residential patient and staff buildings, pharmacy, postal and administrative units, as well as associated facilities to support varied farming operations intended to help sustain the institution, including a large dairy. Treatment protocols during much of Oakdale's more than half-century of operation included a regimen of rest, fresh air year around, and a nutritious diet. Before its naming in 1839, TB had been called "consumption" during much of its 4,500-year history as a human disease dating from Babylonian writings and Egyptian mummies. Beginning with just eight patients but ending its first year with 45 in residence, Oakdale continued to grow, which forced repeated expansions, including a major one during 1926. Size of the associated farm ground also was increased to nearly 500 acres (200 hectares) from an original 280 acres (110 hectares). Its patient census peaked during the 1940s at about 400. Improving public health standards and development of the first drug cure for TB in 1944 caused Oakdale usage to decline and the facility was morphed briefly into an alcohol treatment center about 1960 as alternate uses were sought. The entire facility and land were transferred to University of Iowa ownership in 1965, and the last tuberculosis patient was transferred to University of Iowa Hospitals and Clinics in 1981.The university established its Agricultural Medical Research Facility at Oakdale in 1966 as the first step of a major evolution of this rural satellite campus, which now also houses the State Hygienic Laboratory in a new facility, as well as the university's 197-acre Oakdale Research Park, where, among many other facilities, the National Advanced Driving Simulator is located. A separate entity that also carries the Oakdale name because of its proximity but was never a part of historic Oakdale, the Iowa prison system's Iowa Medical and Classification Center is located immediately across the road from the main Oakdale campus. The facility was opened in 1969 on slightly more than 50 acres (20 hectares) and now has more than 500 beds. It includes prison system entry from all parts of Iowa, plus the statewide prisoner medical treatment and psychiatric units. It also houses a maximum security facility.
