Emergency Stabilization of the White Point Landslide
The White Point Landslide destroyed a portion of a coastal roadway and threatened nearby residences in the Palos Verdes Peninsula of Southern California. The presence of a weak bentonite layer facilitated rapid mobilization of the landslide, which moved about 20 m (60 feet) towards the ocean in about 20 minutes. This article describes the design and implementation of an emergency program intended to stabilize the coastal bluff east of the landslide area and stop slope instability from propagating towards nearby residences. The stabilization program consisted of dewatering drains installed using horizontal directional drilling (HDD) combined with steeply inclined high capacity tieback anchors. This article also describes the conventional slope stability analyses and numerical modeling which were performed to better understand the mode of failure, nature of the failure, and impact of the proposed stabilization.
