Geotechnical Engineering in San Diego

San Diego geotechnical engineering addresses the region's complex subsurface — formational soils with expansive clay potential, sandy coastal terrace deposits, liquefiable alluvial soils near Mission Bay and the San Diego River, and the seismic hazard from the Rose Canyon Fault running directly beneath the city.

Local Engineering Context

Authority Having Jurisdiction: City of San Diego Development Services Department
Building Code: 2022 CBC — geotechnical investigation required for commercial and residential projects in designated geologic hazard zones
Energy Code: N/A
Local Market: San Diego's biotech and life science industry (Torrey Pines Mesa), military construction, and active residential market — particularly hillside and canyon-adjacent development — create significant demand for geotechnical investigation and engineering.
Climate & Engineering Conditions: Zone 7-10; the Rose Canyon Fault system creates significant seismic hazard (SDC D) for central San Diego; liquefaction potential exists in alluvial floodplains; expansive soils in marine terrace deposits are common; coastal erosion and cliff stability are concerns for bluff-top sites.
