Excavation & Retaining Walls Across Salt Lake County, UT

Utah's 2nd largest city. Deep Bonneville clay on the east, Oquirrh alluvial fan with caliche on the west, 1970s aging infrastructure throughout. Flat terrain means drainage must be engineered — not assumed.

Seven-mile span from Jordan River to Oquirrh Mountains. East side: river alluvial clay. West side: alluvial fan with caliche hardpan that requires ripping or hammering. Soil assessment before every project.

One of Utah's fastest-growing cities. Jordan soil series (clay, alkaline, high salinity) on the east. Oquirrh alluvial fan with caliche on the west. Seasonal high water table peaks March–June.

Dramatic east-west soil split. West: flat Bonneville clay. East: glacial moraine from Cottonwood Canyons — granite boulders, quartzite cobble, and coarse gravel requiring hydraulic hammers. Most demanding residential terrain in the county.

Lake Bonneville expansive clay throughout. One of Utah's fastest-growing cities — from 1,500 residents in 2000 to 55,000+ today. Oquirrh foothills rising to the west. New construction dominates.

Three terrain zones: rocky Wasatch foothills, Traverse Mountains volcanic tuff (unique geology), and I-15 valley clay corridor. Straddles Salt Lake and Utah County lines. Premium hillside lot specialists.

Three waterways: Jordan River, Big Cottonwood Creek, Little Cottonwood Creek — all influencing soil drainage. Deep Bonneville valley clay, flat terrain, high-to-moderate liquefaction zones per Utah Geological Survey.

Incorporated 2016. Median build year 1972 — aging infrastructure city-wide. Rocky East Bench terrain toward Mt. Olympus on the east. Valley clay on the west. Infill and aging utility replacement common.

The USDA named a soil series after Taylorsville — calcareous, slowly permeable silty clay loam on flat Lake Bonneville lake terraces. 1960s–70s housing stock. Drainage engineering is the critical factor on every project.

Bonneville clay valley floor with Jordan River water table. Home to the redeveloped Bingham Junction (former Midvale Slag Superfund site). 1950s–80s housing stock with aging infrastructure throughout.

Large estate lots between Big and Little Cottonwood Canyons. Rocky East Bench alluvial soils — quartzite cobble and sandstone fragments. Canyon runoff drainage critical. Premium residential character; boulder walls listed first.

The City Between the Canyons — East Bench at 4,820 ft between Big and Little Cottonwood Canyons. 68" annual snowfall. Rocky alluvial soils. Canyon drainage is the defining excavation challenge.

Straddles Salt Lake and Utah County lines. Rolling terrain — dense Jordan River clay in the valley, sandy loam toward Traverse Ridge. Large lots, rough-graded subdivisions, retaining walls are structural necessities.

Built overnight as a WWII Army Air Base in 1942; converted to civilian suburbs using military infrastructure. WWII-era utility systems now 80+ years old require careful replacement. Deep Bonneville clay on the Kearns-Benion hill.

The USDA "Magna series" soil is classified as poorly drained, saturated within 24 inches of the surface seasonally — the highest water table conditions in the county. Oquirrh foothills rise to the east. Dewatering planning on every deep project.
