What we investigate in Boise
Two forces drive most of the structural losses we evaluate near Boise: the expansive foothill clay that swells and shrinks under foundations, and wildfire pushing off the sage-steppe into the wildland-urban interface. We document what actually failed to a standard that holds up, and a licensed engineer responds within 24 hours with no travel charges.
The conditions we see in Boise
Much of the Boise area, and the foothills in particular, sits on montmorillonite-rich expansive clay weathered from volcanic-derived sediments. That clay swells when it takes on water and shrinks as it dries, and the movement heaves slabs, driveways, and garage floors and stresses foundations; it has been mapped as an engineering problem specific to the Boise foothills. The high-desert climate compounds it, because low annual precipitation still comes with several months of freezing temperatures, so frost heave and seasonal moisture swings both work on a footing. Telling clay movement apart from frost, drainage, or a construction defect is often the whole question on a claim.
Boise also sits in seismically active Basin and Range terrain. The Squaw Creek, Jakes Creek, and Big Flat faults are active north-south structures within about 25 miles of the Treasure Valley, close enough to cause significant damage in a magnitude 6 to 7 event, and the 2020 magnitude 6.5 Stanley earthquake in the Sawtooth Mountains was felt in Boise about 72 miles away, confirming the regional reach. Strong shaking could trigger liquefaction and slope failure in susceptible ground. The Boise River adds another driver: it reached its roughly 7,000 cfs flood stage in the wet spring of 2017 and flooded low-lying reaches near the city, and FEMA maps 100-year flood zones along the corridor for the far larger flows still possible there.
How we help in Boise
The evaluations Boise cases usually call for
- Foundation, soil, and seismic evaluation
When a slab heaves or a foundation cracks near Boise, the cause can be expansive foothill clay, frost, flood saturation, seismic movement, or a construction defect. Our licensed engineers evaluate the structure and the way the soil and ground behaved together, then document which one is responsible in a form that holds up in a claim or in court.
Our structural engineering services- Flood and water loss investigation
After Boise River flooding, a rapid snowmelt event, or a component failure, we determine whether the damage came from the water, a condition that predated it, or a defect. We tie each conclusion to the physical evidence at the property rather than assumption, so it stands up when the loss is disputed.

Fire origin & cause
Fire origin and cause in Boise
Boise lies in a sage-steppe ecosystem where fast-moving fire runs through dry summer fuels and pushes into the wildland-urban interface, especially in the rugged foothills. The 2008 Oregon Trail Fire took ten homes and a life, and the 2009 Highway 16 Fire destroyed four homes and damaged more than 60 structures in the Ada County foothills, which is why the city and county adopted wildland-urban interface building and fire codes that call for ignition-resistant construction. When wind drives a rangeland or foothill fire into structures, the origin evidence goes fast, and pinning it down is what a claim turns on.
Our NAFI-certified investigators build every determination under NFPA 921. They document the scene methodically, trace burn and char patterns back to the area of origin, evaluate the electrical and mechanical systems, and rule out candidate causes until the physical evidence supports one, accidental or incendiary. Reaching the scene early preserves evidence that wind and firefighting can erase, and the same investigator records the finding in a written report and testifies to it at deposition and trial.

Common questions
Forensic engineering in Boise, Idaho
A different question about your case? An engineer, not a call center, answers within 24 hours.
Is foundation movement in Boise from expansive clay or from frost?
It can be either, and often both. The montmorillonite-rich foothill clay swells and shrinks with moisture, and the region's multi-month freezing winters drive frost heave. We evaluate the damage pattern and the site conditions to determine the cause rather than assume it.
Can you tell wildfire damage from damage that was already there?
Yes. Separating fire, ember, and smoke damage from pre-existing wear or a defect is a core part of a wildland-urban interface investigation in the Boise foothills, and it is usually the point the claim turns on.
Do you charge travel to reach Boise?
No. We work Boise-area cases from our Omaha lab and Los Angeles office with no travel charges, and a licensed engineer responds within 24 hours.
