West Valley City is a city in Salt Lake County and a suburb of Salt Lake City in the U.S. state of Utah. The population was 140,230 at the 2020 census, making it the second-most populous city in Utah after Salt Lake City. The city incorporated in 1980 from a large, quickly growing unincorporated area, combining the four communities of Granger, Hunter, Chesterfield, and Redwood. It is home to the Maverik Center and Utah First Credit Union Amphitheatre.

The earliest known residents of the western Salt Lake Valley were Native American bands of the Ute and Shoshoni tribes.

The first European people to live in the area were the Latter-day Saints. The Euro-Americans arrived in the Salt Lake Valley in 1847. The area was first staked out by settler Joseph Harker and his family in the area they named as "over Jordan" (referring to the land west of the Jordan River, which runs through the valley).

The Granger area was settled by Welsh pioneers who came to Utah with Dan Jones in 1849. Irrigation systems and agriculture were developed in the area, and Elias Smith proposed the area's name on account of its successful farming. The population of Granger and its vicinity was about 1,000 people in 1930.

Hunter was not settled until 1876. This settlement was started by Rasmus Nielson, Edward Rushton, August Larsen and about seven others along with their families. Irrigation began in 1881 and the main crop was fruit trees.

The city began to experience rapid growth in the 1970s, when the area that is now West Valley City consisted of the four separate communities of Hunter, Granger, Chesterfield, and Redwood. These four unincorporated areas merged in 1980 to form the present-day city. During the 2002 Olympic Winter Games, West Valley City was the official venue for men's and women's ice hockey.

On May 19, 2011, the city unveiled an official plan to create a downtown area for the city over the course of 10 years, building on plans and development that already existed. It will be known as Fairbourne Station (named after Joseph Fairbourne, an early settler who operated a weigh station in the area in the late 19th century) and will consist of approximately 40 acres (16 ha), costing $500 million to build. The center will include a civic center (consisting of city hall, a courthouse, police headquarters, and a library), an eight-story Embassy Suites hotel, a plaza, and residential development, as well as the end of the TRAX Green Line, and a stop on the 3500 South MAX bus rapid transit line. Valley Fair Mall and the Maverik Center are located nearby, as is I-215. As of 2016[update], the development is incomplete with the TRAX line having opened in 2011 and the hotel in 2012, but the City Hall and the government center still under construction.

Serial killer Ted Bundy was arrested in Granger on August 16, 1975, on a routine traffic stop.

According to the United States Census Bureau, the city has a total area of 35.5 square miles (91.8 km2), of which 35.4 square miles (91.7 km2) is land and 0.1 square miles (0.2 km2) (0.17%) is water.

West Valley is located on the northwest side of the Salt Lake Valley between Salt Lake City on the north, South Salt Lake on the east, Magna on the west, and Taylorsville and Kearns Township on the south. The Oquirrh Mountains loom over the city to the west, while the Jordan River marks the eastern boundary.

West Valley City has a nonpartisan, strong city manager form of government, which means that the city manager is analogous to a corporation's CEO, while the mayor fills a role similar to chairman of the board, with the City Council acting as the "board". The mayor is a voting member of the City Council. The West Valley City Council meets each Tuesday night at 6:30 PM, except fifth Tuesdays. City Hall is located at 3600 South Constitution Boulevard.

The mayor and six councilors are elected to four-year terms. Mayoral elections are held the same year as three of the councilors. The other three councilors are staggered two years from the mayoral. Two council seats are at-large, or citywide, and the remaining four seats represent districts of approximately 28,000 residents. Officials are not subject to term limits. As of November 2013[update], the most recent election was held in November, 2013.

In the Utah State Legislature, West Valley City is in Senate Districts 1, 3, 5, and 12 represented by Democrat Luz Escamilla, Democrat Gene Davis, Democrat Karen Mayne, and Republican Daniel Thatcher and House Districts 30, 31, and 33, represented by Republican Fred Cox, Republican Sophia DiCaro, and Republican Craig Hall. Federally, West Valley City lies in the 2nd and 4th congressional districts, represented by Republicans Chris Stewart and Burgess Owens.

The West Valley City Police Department (WVCPD) provides law enforcement services to the city. As of 2021[update] the police chief is Colleen Jacobs, a 21 year veteran of the department, who oversees 218 sworn officers and 47 support staff.

In 2013, the city police's narcotics unit was disbanded after an officer-involved critical incident revealed drugs and money had not been booked into evidence. Officers in the unit were also found to be keeping change and small items from seized vehicles, and placing tracking devices on potential suspects' vehicles without warrants.

In 2016, Officer Cody Brotherson was killed in the line of duty, the department's only such fatality.

In 2019, an officer shot and killed a handcuffed man who was attempting to pull an officer's gun out of its holster: this killing was found legally justified by the district attorney.

West Valley City is on the same address grid system as Salt Lake City, and therefore follows the same street numbering system. I-215 runs through eastern portions of the city parallel to I-15, which lies farther east of the city. The SR-201 freeway lies along the northern border with Salt Lake City and continues west into Magna as an expressway.

The Mountain View Corridor also runs through the western portion of the city. The city is served by several bus routes operated by the Utah Transit Authority, and an intermodal transportation hub located in the city center near Valley Fair Mall and the Maverik Center. In addition to local bus routes, the West Valley Intermodal Hub is serviced by TRAX light rail and MAX bus rapid transit (BRT) lines.

To the north of Parkway Boulevard exists a significant number of light industrial development. South of Parkway is mostly residential and commercial, including Valley Fair Mall and the Maverik Center. The Westshire neighborhood is located directly south of Valley Fair Mall and consists of 160 homes built by modernist architect Ron Molen. This neighborhood is unique in that all homes were built in the 1960s and 1970s in the Mid-Century Modern style and are excellent examples of modernist residential architecture. West Valley City planners are currently developing a planned mass-transit anchored Downtown area near the Valley Fair Mall with the emergence of the Fairbourne Station as a gathering place and revitalization of the mall.
