Sunnyvale Civic Center

The existing 26-acre Civic Center Campus, first constructed six decades ago, is undergoing a major modernization to better serve the city’s growing population. Four buildings will be demolished with services consolidated into a 4-story, approximately 117,200-SF City Hall building over one 60,000-SF level of underground parking. The Public Safety building will also be renovated and expanded with a two-story addition.

For Phase 1, Langan performed a geotechnical investigation to evaluate subsurface conditions and potential geologic hazards at the site and to provide recommendations for the geotechnical aspects of the proposed development. We also performed a seismic hazard analysis to develop site-specific response spectra.
