The mission of the Work Group was to develop short- and long-term strategies to reduce landslide impacts and improve transportation reliability throughout the corridor.
Potential strategies to reduce landslide interruptions and impacts were explored by the Work Group.
Strategies were outlined and evaluated for implementation time, complicating factors,
and short, moderate-, and long-term effectiveness to reduce or prevent landslides.
The Work Group recognizes that measurable long-term reduction in landslide-related impacts to passenger service will require substantial investments in capital improvement projects.
Depending on the financial resources available, as well as factors such as permitting, design, and construction scheduling, the time required to achieve significant reductions in landslide-related service interruptions will likely take one or more decades. less
