Montezuma Dredge Material Deposit and Wetlands Restoration

Through a public-private partnership with the City of Oakland, the Montezuma team established a 20 million cubic yard upland disposal site, providing an efficient, sustainable, and environmentally acceptable alternative to in-bay and ocean sediment disposal to address a 50-foot marine channel deepening project. The project is simultaneously restoring over 1,800 acres of tidal wetlands. Northgate worked on initial conceptual planning stages through investigation and design phases and construction, including geotechnical design and monitoring for levees construction on approximately 300 acres of dredge settling ponds for future tidal marsh restoration, as well as sediment quality evaluations, site operations, and project monitoring. To date, the site has received 6 million cubic yards of dredged sediment from local and federal dredging contracts for restoration.
