A case history of one of the most highly publicized landslides in the history of the California Department of Transportation is presented. In the spring of 1979, the recognition of an incipient and potentially dangerous massive slide above steep sandstone bluffs adjoining the Pacific Coast Highway (CA-1) between Malibu and Santa Monica necessitated closure of this vital transportation link. The installation of an extensive and unique warning system plus a rock fall catchment area permitted partial reopening one month later while the slide investigation proceeded. The correction ultimately selected involved a partial unloading and slope reinforcement. The four-way warning system proved to be extremely useful in permitting the partial reopening of the highway while providing for the general safety of the traveling public and adjacent home owners. The use of rock dowels for slope reinforcement reduced the required excavation to achieve stability by more than 1 million cu yd in extremely difficult terrain. (Author)
