The Unstable Slopes Program analyzes slopes adjacent to state highways for potential impacts that a failure could cause. Such failures include:
- Rock falls; and
- Debris fills.
Historically, ODOT has evaluated rock fall hazards, but has expanded the program to include other types of unstable slopes. Under the revised program, ODOT is able to include economic factors in its analysis as well as hazard and engineering considerations so that sensible repair priorities can be more easily obtained.
As the Unstable Slopes Program is in its infancy, no data is available for publication, but if you have questions, please contact us.
