The berths had been used by the Navy, and significant amounts of trash and debris were present in the top 5 feet of maintenance material. The new work material was clay.

DOF provided the following services:

• Prepared cost estimates for multiple dewatering/water treatment applications including geotextile bags and centrifuges
• Calculated hydraulic dredge production using proprietary computer model for hydraulic throughput requirements to size geotextile bag and centrifuge dewatering systems
• Calculated available capacity of upland disposal area
