Structural Expert Witness in Santa Rosa: Local Conditions That Matter
The Rodgers Creek Fault runs directly beneath Santa Rosa — the presumed northern extension of the Hayward Fault. Seismic design and retrofit of pre-modern-code homes is a genuine safety issue here, not a formality. Santa Rosa cases often turn on causation and standard of care: was the damage seismic, settlement, water, or defect — and did the design or construction meet the California Building Code? Dr. Mousavi brings a Ph.D. in structural engineering (Texas A&M), 20+ years of experience, 7,000+ projects, and peer-reviewed research to those questions.
Seismic Conditions
The Rodgers Creek Fault runs directly beneath Santa Rosa — the presumed northern extension of the Hayward Fault. Seismic design and retrofit of pre-modern-code homes is a genuine safety issue here, not a formality.
Soil & Foundations
Santa Rosa sits on valley alluvium with liquefaction-prone zones along Santa Rosa Creek. Foothill properties toward Rincon Valley and Bennett Valley deal with expansive clay and slope conditions.
Permitting in Santa Rosa
Sonoma County and Santa Rosa permit teams processed thousands of fire rebuilds after 2017 and know exactly what complete submittals look like. Complete engineering upfront is what keeps rebuild and remodel permits moving.
