Landslide Stabilization
Home Depot Emergency Landslide Stabilization
Laguna Woods, California
Emergency stabilization of a major landslide above the Home Depot parking lot using drilled piers, grade beams, and tiebacks.
The Problem
Site Conditions That Drove the Work
A major landslide occurred above the Home Depot parking lot in Laguna Woods, threatening Calle Sonora Avenue and all existing utilities. The emergency nature of the failure required rapid mobilization and a stabilization system capable of arresting movement on a large scale.
The Solution
J.C. Baldwin installed 53 caissons at 4-foot diameter to 70 feet deep, 159 tiebacks loaded to 280 kips at 100 feet long, along with 493,000 pounds of steel beams and 2,910 cubic yards of concrete. The project also included 63,000 cubic yards of grading.
Outcome
The stabilization system protected Calle Sonora Avenue, all existing utilities, and the adjacent commercial property from further landslide displacement.
