Subdivision Landslide Caused by Faulty Construction, Not Water Intrusion

Summary:


This frame from the 2D interactive animation illustrates the movement of
earth as recorded by boring samples above the future site of catastrophic
failure, which was caused by earth sliding over the site of an ancient
underground landslide.

A Southern California residential subdivision suffered a catastrophic landslide, which destroyed several homes and condominiums, and caused several million dollars of property damage. Our client, a subcontractor, was accused of improperly installing sewer lines and a drainage ditch, which were alleged to have leaked a sufficient amount of water to undermine adjacent soil, which caused the landslide to occur.

The defense countered that plaintiff’s theory was implausible, and that instead, a massive buildup of fill material created too heavy of a load on top of the site of an inherently unstable ancient landslide, which caused a new landslide to occur.
