Concrete shear pins were installed in two rows across the landslide, on the slope below the residence, and a tieback anchored shotcrete wall was constructed to stabilize the headscarp of the landslide and protect the rear yard and house. The shear pins and the shotcrete wall were combined as a system to stabilize the landslide. Coordination with landslide repairs on the neighboring properties allowed heavy equipment access and reduced costs.
