Hillside developments in the Los Angeles hillsides have been performed in communities from Woodland Hills to Hollywood to Pasadena and Glendale. Developments involving hillside grading and construction over natural slopes have considered the geologic conditions unique to Los Angeles hillsides. The geologic conditions have been complicated by past grading prior to adoption of modern codes. Studies have determined feasible development schemes that consider safe and stable sites and the requirements of the City Building Codes.

The causes of damage to developed properties have been determined for sites throughout California. The majority of our projects have involved southern California developments from Ventura to San Diego. The scope of work performed for homeowners and insurance companies has included visual evaluation of damage to comprehensive studies to arrive at schemes for repair and stabilization. Treatments for fill settlement, expansive soil movement and slope instability are tailored to the magnitude of the hazard and the desired level of performance of the improvement. The extent of property damage associated with major earthquakes in northern and southern California has been determined along with advice to repair the earthquake damage. Investigations of properties have been performed to evaluate the 1987 Whittier Narrows earthquake, the 1989 Loma Prieta earthquake in the San Francisco Bay area, the 1992 Landers earthquake, and the 1994 Northridge earthquake in southern California.
