ENGEO is providing geotechnical engineering and stormwater consultation for the redevelopment of 65 acres of former Port of Oakland land adjacent to the Oakland Estuary and Jack London Square. The project will include an environmentally sustainable, mixed-use urban master plan with 3,100 residential units; 200,000 square feet of retail and commercial space; and 30 acres of parks, public trails and open space, new marinas, and renewed wetlands. The project will consist of a combination of low-, mid-and high-rise construction and includes reusing a historic wharf structure founded on a combination of wood and concrete piles.
Geotechnical constraints of the project include high seismicity, liquefiable sand, soft Bay deposits, and shoreline stability. The site needs to be raised several feet to address potential future sea-level rise, which will result in a consolidation settlement of the Young Bay Mud. The high seismicity could also result in slope deformations along the water’s edge due to the low strength of the Young Bay Mud. ENGEO developed innovative approaches to both these effects that best fit the project constraints.
ENGEO worked closely with the marine structural engineer to evaluate the interaction of the structure and the waterside slope to determine if seismically induced slope movement would damage the structure and to develop cost-effective mitigation for areas where the structure was threatened. ENGEO able to develop an innovative approach through this close collaboration that was peer-reviewed and externally reviewed by a panel of experts assembled by BCDC.
