Commercial Structural Engineering in Napa: Local Conditions That Matter
The 2014 South Napa earthquake (M6.0) ran through the West Napa Fault right under the city — historic masonry downtown and older homes took real damage, and post-quake retrofits are a signature Napa need. City of Napa and Napa County review carefully — winery and hillside projects face additional land-use steps. Our stamped packages are engineered to satisfy structural review the first time. Commercial work in California carries higher seismic demands and stricter review than residential — our engineers deliver the analysis and documentation quality that Napa plan check, lenders, and building officials expect.

Soil & Foundations
Napa Valley floor alluvium, creek-adjacent liquefaction zones, and hillside vineyard soils on the valley walls each demand different foundation strategies. Winery cave and hillside projects add slope and geotechnical coordination.
