Approach
Increase resilience to landslides by protecting roads and structures from higher landslide frequency, and reduce management activities that increase landslide potential.
Tactics
- Increase maintenance frequency.
- Stabilize slopes mechanically or with vegetation.
- Improve drainage.
- Alter road surface type and grade.
- Elevate roads to allow landslides to pass underneath.
- Compensate for landslides by reducing weight.
- Locate/relocate roads in areas less vulnerable to landslides.
- Redesign roads to avoid over-steep cut and fills, and to improve water drainage; design debris catches on major access roads.
- Use seasonal road closures to keep visitors away during most hazardous times of year.
