Continuing repairs
This hillside, near the intersection of PCH and Topanga, slid onto the highway during the winter of 2005, when Los Angeles got more rain than Seattle. After the worst of the mess was cleared away, work began on stabilizing the hillside. Drainage pipes were inserted into the hillside, to allow water to flow out without taking the soil with it. Now the hillside is being covered with fabric -- I'm not sure what kind -- to further stabilize the slope.
The final stage, I believe, will be to seal the slope with concrete. Several hillsides on PCH have already received this treatment. However, I noticed that at least one of them slid underneath the concrete this winter. Its covering is cracked and bubbled in several places, and vegetation is starting to work its way through.
