Landslide Stabilization
Coast HOA Landslide Stabilization
San Clemente, California
A caisson-and-tieback stabilization project protecting eight homes threatened by a deep landslide in Southern Orange County.
The Problem
Site Conditions That Drove the Work
Eight homes in Southern Orange County were threatened by a deep landslide. The Coast Homeowners Association needed a stabilization solution that could arrest movement at depth and protect the homes and surrounding improvements from further displacement.
The Solution
J.C. Baldwin installed a series of 31 caissons ranging from 50 to 80 feet deep and 31 tiebacks loaded to 280 kips at lengths of 170 feet, connected by a 372-foot shotcrete grade beam. The project also included grading, drainage improvements, and construction management.
Outcome
The stabilization system arrested the deep-seated landslide and secured all eight homes. The project demonstrates the firm's capacity for large-scale geotechnical work in developed residential environments.
