Castro Cove Lagoon (Contaminated Sediment Remediation), Richmond, CA

Castro Cove Lagoon consisted of hydraulic dredging 60,000 cy of contaminated material, capping the dredged area with a 30,000 cy sand cap, and a 30,000 cy mud cap. Bay Marine Services worked closely with both the URS the design engineers, and Chevron the owner to build a hydraulic sand placement and delivery system specifically designed for the job. Additionally BMS provided a custom 5 channel Ross sweep system to provide high resolution surveys in order to evaluate cap thickness.

Lastly, BMS performed dredge positioning and quality control services utilizing Hypack dredge positioning, created 3 dimensional dredge templates, and performed volume computations.
