Prior to the first European settlers to the area, the earliest known residents of the western Salt Lake Valley were Ute and Shoshoni tribes of Native American Indians. European Latter-day Saints arrived and settled in the Salt Lake Valley in 1847.
The area would go on to be comprised of four separate communities – Chesterfield, Granger, Hunter, and Redwood. Welsh Latter-day Saints settled in the Granger area in 1849, and by 1930 Granger and its surrounding area had grown to be home to around 1,000 inhabitants. It was not until 1876 that Hunter was settled. Irrigation was developed 5 years later, and the area became known for its growth and cultivation of fruit trees.
The communities of Chesterfield, Granger, Hunter, and Redwood saw rapid growth in population in the 1970s, and the four unincorporated areas came together in 1980 to form West Valley City.
The city unveiled plans in 2011 for a vast, 10-year investment plan into its infrastructure, creating a downtown area comprising approximately 40 acres at a cost of $500 million.
