Landslide Mitigation & Slope Stabilization — South Eugene Hills, Oregon

This landslide mitigation project took place in the South Eugene Hills and was completed in two phases, beginning with an emergency response to restore safe access for residents.

The initial landslide was blocking nearly the only entrance and exit for a community of 30+ families, creating an urgent safety concern. Our first priority was establishing a safe, one-way access lane so residents could safely enter and exit the neighborhood.

Once access was restored, we built a working pad and began reshaping the top of the slope back to a safe grade, working our way downward. During this process, we were able to chase bedrock across much of the hillside, which is always a positive sign in landslide mitigation and slope stabilization work.

On the north end of the slide, the material never became fully competent, and we also identified active water runoff in the area. Because of these conditions, we voiced concerns to the customer about the potential for future slope failure. While the decision to install wire mesh reinforcement was left to the client, we strongly recommended it as a necessary long-term solution.

A few months later, the community board reached out to move forward with Phase Two of the project.

Due to the steep natural slope above the slide, we recognized that suspending mesh directly from the brow would add unnecessary stress and weight, which could cause a failure on its own. Instead, we set posts at a safe distance above the brow and suspended the mesh using cables and turnbuckles. This approach allowed us to shape the mesh tightly to the slope while reducing stress on the previously failed area.

As a result of this project, the community became more aware of early warning signs of slope failure. On a different section of the property, they were able to identify slope movement early and contact us before a full failure occurred, allowing us to mitigate the issue before it became a larger and more costly problem.
