Hillside Foundation Engineering in San Francisco: Local Conditions That Matter
Bay Area soils include bay mud, sand, and rock. Liquefaction risk is significant in some areas — geotechnical assessment is critical. San Francisco is in a major seismic zone near the San Andreas Fault. Seismic design and soft-story retrofits are mandatory for many buildings. Hillside lots concentrate the hardest geotechnical questions in California. Our engineers design San Francisco hillside foundations around what the slope, soil, and seismic setting actually demand — and we coordinate with geotechnical reports when the city requires them.
