Ellison Conservation Center for Wildlife Care

The Conservation Center for Wildlife Care, operated by the Peninsula Humane Society and the Society for the Prevention of Cruelty to Animals (SPCA), is located on an approximately 170-acre site on the northeast side of Congress Springs Road (Highway 9). This property is within a geologically complex area, with landsliding and multiple traces of the San Andreas fault extending through the site. It is within the mapped Alquist-Priolo Earthquake Fault Zone. Unique geotechnical challenges are an extensive quarrying history and significant amounts of undocumented fill and presence of the San Andreas fault. Langan performed a geologic and geotechnical investigation, which included geologic mapping, laboratory testing, and slope stability analyses. Langan also provided geotechnical and geologic observation services during construction to repair portions of the main access road throughout the property.
