What we investigate in Eugene
Eugene's structural risk is led by the ground moving under it. Onshore crustal faults and the offshore Cascadia Subduction Zone make earthquakes Oregon's costliest hazard, and older downtown masonry is built to take them badly. We document what actually failed, and a licensed engineer responds within 24 hours.
The conditions we see in Eugene
Eugene faces earthquakes from two directions. Onshore crustal faults sit under the city, and offshore the Cascadia Subduction Zone, a roughly 700-mile fault that last ruptured near magnitude 9.0 in January 1700, remains capable of a great earthquake. Seismic loss is the largest natural-hazard exposure across the Pacific Northwest. The older unreinforced masonry in and around downtown is the vulnerable stock, with brick and stone bearing walls that lack reinforcement and are not tied to the floors and roof, so even modest ground accelerations can do real damage.
The Willamette River also floods Eugene. The December 1964 Christmas flood is the largest event recorded in Lane County, and in a major flood the river reoccupies its historic floodplain across the valley. The climate is mixed-marine, IECC zone 4C, with cool, wet winters that drive moisture intrusion, wood rot, and roofing wear, and local slope failures run to smaller slides and slumps at overall moderate risk.
How we help in Eugene
The evaluations Eugene cases usually call for
- Seismic and structural evaluation
When masonry cracks or a wall separates in Eugene, the question is whether it is seismic movement, flood saturation, a slope slump, or a construction defect. Our licensed engineers evaluate the structure and the ground together, with attention to how unreinforced masonry behaves under load, and document which cause is responsible.
Our structural engineering services- Flood and water loss investigation
After a Willamette flood or a wet-winter water loss, we determine what the water did to the foundation and framing and whether the damage came from the flood, marine-driven moisture, or a condition that predated it. Each conclusion rests on the physical evidence at the property.

Fire origin & cause
Fire origin and cause in Eugene
Eugene's sharpest fire risk sits in the forested south hills, where trees meet homes at the wildland-urban interface. The September 2020 Holiday Farm Fire in the nearby McKenzie River corridor burned about 173,000 acres and destroyed 517 homes after fallen power lines ignited it during a high-wind east-wind event. When a fire moves on wind like that, origin evidence is lost fast, and pinning it down decides the claim or the case.
Our NAFI-certified investigators work to NFPA 921. They examine the scene methodically, trace burn and char patterns back to the area of origin, evaluate the electrical and mechanical systems and any implicated utility equipment, and rule out causes until the evidence supports one, accidental or incendiary. The investigator preserves that evidence early, documents the finding, and testifies to it at deposition and trial.

Common questions
Forensic engineering in Eugene, Oregon
A different question about your case? An engineer, not a call center, answers within 24 hours.
Is Eugene really at risk from a major earthquake?
Yes. The city sits over onshore crustal faults and near the offshore Cascadia Subduction Zone, which makes seismic loss the region's largest natural-hazard exposure. Older unreinforced masonry downtown is the most vulnerable stock, and that shapes how we evaluate it.
Can you assess flood damage after the Willamette recedes?
Yes. Much of the structural evidence remains after the water drops, and we evaluate the foundation, framing, and finishes to document what the flood caused versus what predated it.
Do you charge travel to reach Eugene?
No. We work Eugene-area cases from our Omaha lab and Los Angeles office with no travel charges, and a licensed engineer responds within 24 hours.
