Taylorsville is a city in Salt Lake County, Utah, United States. It is part of the Salt Lake City, Utah Metropolitan Statistical Area. The population was 58,657 at the 2010 census. Taylorsville was incorporated from the Taylorsville-Bennion CDP and portions of the Kearns CDP on April 24, 1996. The city is located adjacent to interstate 215 and Bangerter Highway. It is centrally located in the middle of the Salt Lake Valley.
The area called Taylorsville today is made up of three historic communities in the central part of Salt Lake County: Taylorsville, Bennion, and Kearns. These communities incorporated through a vote of the people with over 70 percent approval in September 1995. The city officially became the City of Taylorsville during the centennial anniversary of Utah's statehood in 1996.
The land on which Taylorsville is located is part of an interconnected alluvial plain that was formed by the wearing down of the Wasatch and Oquirrh Mountains to the east and west. Beneath the surface Taylorsville sits on more than a kilometer of unconsolidated rock, sand, and clay. The inactive Taylorsville Fault has been traced down the center of the Salt Lake Valley. Lake Bonneville shaped the topography of the area and deposited lake bottom clay and sand. As Lake Bonneville dried up over the past 14,000 years, the salt from the breakdown of rock remains, making the soil alkaline. Like most desert soils, it has little organic material and is hard to work.
A broad, east-west running ridge called 'Bennion Hill' rises perhaps a hundred and fifty feet above the surrounding area. Bennion Hill is the eastern end of a wide ridge which rises toward Farnsworth Peak in the Oquirrh Mountains to the west.
