RESIDENTIAL

Group Delta, an NV5 Company, conducted the Hollywood Surface Fault Rupture Hazard Evaluation to assess seismic risks for redevelopment sites impacted by the Hollywood Fault within the Alquist-Priolo Earthquake Fault Zone in Los Angeles, California. The project focused on mixed-use and school properties near Hollywood Boulevard, Vine Street, Yucca Street, and Argyle Street, and was critical for determining compliance with 50-foot setback requirements and informing safe design and permitting strategies in a dense urban setting.

Our team provided geotechnical and seismic services, including fault trenching, core borings, and cone penetration testing to assess rupture hazards. Our team performed detailed core logging and geologic modeling to characterize subsurface conditions and identify fault traces. They prepared technical reports and participated in review sessions with city planners, state geologists, and technical representatives to support permitting and regulatory compliance. Additional services included civil engineering, infrastructure design, site permitting, traffic engineering, surveying and mapping, and construction engineering inspection—each tailored to the complex geologic and urban conditions of the Hollywood area.

Added Value

• Regulatory Alignment and Risk Mitigation: Our team’s fault rupture hazard evaluation ensured full compliance with Alquist-Priolo Earthquake Fault Zone regulations, helping the client avoid costly redesigns and permitting delays.
• Technical Precision in Complex Urban Geology: Through advanced subsurface investigations, including trenching, borings, and geologic modeling, our team delivered high-resolution fault characterization critical for safe redevelopment in a densely populated area.
• Integrated Engineering Support: Our team provided civil engineering, permitting, traffic planning, and inspection services, streamlining coordination across disciplines and enhancing project efficiency.
