Bluff Stabilization
Colony Cove Bluff Stabilization
San Clemente, California
An 80-foot-tall, 850-foot-long concrete bluff wall with tiebacks and soil nails, completed for the City of San Clemente on time and on budget.
The Problem
Site Conditions That Drove the Work
A coastal bluff failure at the northwesterly end of Pacific Coast Highway in San Clemente required stabilization of an 80-foot-tall bluff face while maintaining full traffic flow on PCH and working within one foot of homes directly above the construction zone.
The Solution
J.C. Baldwin installed 189 tiebacks at 95 feet long and 316 soil nails ranging from 19 to 24 feet long, then constructed an 80-foot-tall by 850-foot-long concrete wall. The work was completed while keeping Pacific Coast Highway in full operation throughout the project.
Outcome
The project was completed on time and on budget in October 1996. J.C. Baldwin received acclaim for the natural aesthetic rock formation finish on the wall and was honored by the City of San Clemente with an award for outstanding service and excellence in construction.
