Excavation Services in Herriman, UT

Herriman is what happens when a mountain-ringed community becomes the most in-demand growth market in the state. Building sites that would have been considered too difficult to develop 20 years ago are now sprouting homes, schools, and commercial centers. The terrain hasn’t gotten easier — the hillsides are still steep, the soil is still rocky and laced with caliche, and the logistics of building on an active construction frontier are still complicated. But the demand for housing in this location has pushed development into ground that requires serious excavation expertise. AccuRite Excavation has the machines and the knowledge for it.

Building on the Growth Frontier

Much of Herriman’s active development is happening on land that wasn’t part of anybody’s building plan a generation ago. The hillsides west of Mountain View Corridor, the slopes approaching the Oquirrh range, and the Traverse Mountain area to the south are being graded into buildable lots at a pace that makes Herriman consistently one of Utah’s fastest-growing cities.

These aren’t valley floor lots. The terrain has grade, the soil has rock, and the infrastructure is being built simultaneously with the homes. New subdivision streets may still be unpaved when the first homes are under construction. Utility mains may be going in on one block while foundation excavation is happening on the next.

Working in this environment requires flexibility and coordination. We sequence our equipment and scheduling around the active development timeline, knowing that site conditions change as the subdivision progresses.

Caliche: Herriman’s Signature Challenge

If there’s one soil feature that defines Herriman excavation, it’s caliche. This naturally cemented calcium carbonate layer is widespread across the city at depths ranging from one to six feet below the surface. It forms in the semi-arid climate as mineral-laden groundwater evaporates, leaving a concrete-like deposit that can be inches to feet thick.

Standard excavation equipment struggles with caliche. A bucket that moves through clay or loose gravel will bounce off a caliche layer. We use ripping teeth and hydraulic hammers to break through it, then remove the material and replace it with drainable fill where necessary.

Caliche’s impermeability is the other problem. Water won’t pass through it, so any drainage system that relies on water moving downward through the soil profile will fail if caliche sits in the way. Around foundations, we break through the caliche and install gravel drains that route water past the impermeable layer and away from the structure.

Hillside Development

A significant portion of Herriman’s buildable land is on slopes. The hillside lots along Juniper Crest, the Mountain Ridge area, and the developments climbing toward the Oquirrh and Traverse ranges require the full suite of hillside excavation work:

• Cut-and-fill earthwork — shaping level building pads from sloped terrain, sometimes moving thousands of cubic yards of material per lot
• Retaining walls — holding grade changes that can exceed ten feet on steep lots
• Driveway construction — cutting access from the road to building pads that may sit significantly above or below road grade
• Drainage systems — intercepting and routing hillside runoff around structures
• Erosion control — managing exposed slopes during and after construction to prevent sediment from affecting neighboring properties and stormwater systems

We’ve done this work throughout Herriman’s hillside developments. Each lot has its own character — the rock depth varies, the slope angle changes, and the caliche appears in unpredictable patterns. Site-specific evaluation before pricing is essential, and we do it on every Herriman project.

Traverse Mountain Area

Herriman’s southern boundary approaches the Traverse Mountains, the same range that creates the Point of the Mountain between Salt Lake and Utah Counties. The geology here differs from the Oquirrh side — volcanic tuff, conglomerate, and sedimentary layers that vary in hardness and stability, similar to what we encounter in Draper.

Building on Traverse Mountain terrain requires geotechnical evaluation to understand the specific rock types and their behavior. Some layers crumble when exposed to weather, affecting slope stability. Others are hard enough to require sustained hammering. The geotech report guides our excavation approach on these properties.

Valley Floor Development

Not all of Herriman is hillside. The lower central areas of the city and the developments along Herriman Main Street corridor sit on more manageable terrain — alluvial deposits with clay, some caliche, but generally flatter and more accessible than the hillside lots.

Residential excavation in these areas follows a more standard sequence: lot grading, foundation dig, utility trenching, and final grade. The caliche may still be present, but the absence of significant slope reduces the overall complexity and cost.

Commercial Growth

Herriman’s population growth has driven commercial development to serve the expanding community. Retail centers, office buildings, medical facilities, and schools have followed the rooftops. We handle commercial site preparation for these developments, including mass grading, foundation excavation, utility installation, and parking lot subgrade preparation.

The soil challenges are the same as residential — caliche, rock, and variable alluvial deposits — but at a larger scale. Commercial pads require engineered compaction to strict specifications, and we verify our work meets the project engineer’s requirements.

Serving Herriman and the Southwest Valley

Herriman borders Riverton to the north, South Jordan to the northeast, and Draper to the east across the Traverse Mountains. We work throughout the southwest valley growth corridor.
