Landslide Projects
GMU’s staff has worked on some of the largest and most high-profile landslide repairs in Southern California, including the La Conchita landslide in Ventura County, the Via Estoril/Crown Valley Parkway landslide in Laguna Niguel and the Big Rock Mesa landslide in Malibu. Our engineers have conducted detailed investigations to determine why slides occur and have engineered innovative solutions to stabilize hillsides and allow for safe re-development.
Sunset Crossing, Diamond Bar
The Sunset Crossing landslide impacted 5 homes in the City of Diamond Bar. After several episodes of movement, GMU was called upon by a design-build contractor to repair the landslide and restore the slope to its original condition. GMU performed a subsurface investigation and helped to develop repair plans that utilized a combination of remedial grading, tie-backs, and geogrid reinforcement for the 1½:1 slope. GMU worked with the City to get the repair plans approved, and then provided geotechnical observation and testing during grading and construction. The project was successfully completed in June 2011. |
