The London Road Landslide took place in the winter of 1969 - 1970. It eventually destroyed 14 homes, and a section of London Road below the Mormon Temple.
The damage could have been much worse; a 12" pipeline carrying jet fuel from the Shell refinery in Martinez to the Oakland Airport ran through the area. An Oakland Fire Marshal ordered the pipeline shut down until the situation was resolved.
The slide was caused in part because of the proximity to the Hayward Fault. Movement fractured sub-surface rocks, and then heavy rains lubricated it, accelerating the movement. Approximately 3 acres of land was directly affected by the slow-moving slide. 2
Neighbors in Piedmont Pines fought the reactivation of the pipeline. Shell was unable to renew their franchise with the city of Oakland in 1985, and decommissioned the pipeline. 1
