Foth was selected by the Town of Barnstable, MA to provide services including hydrographic/topographic surveys, feasibility studies and cost analysis, design, sediment sampling and analysis, permitting, bid document preparation and construction management and oversight for the maintenance and improvement dredging of Barnstable Inner Harbor and within the East Bay.
The Inner Harbor dredging project consisted of mechanically dredging of approximately 8,500 cy of fine-grained sediments. Due to varying levels of sediment contaminants detected, the project utilized both unconfined offshore and upland sites for disposal. Approximately 4,000 cy of sediments were authorized for offshore disposal at the Cape Cod Bay Disposal Site, 500 cy of sediments were disposed at the Bourne Municipal Landfill due to high PAH levels, and the remaining 4,000 CY of sediments were deemed suitable by Massachusetts Department of Environmental Protection for upland beneficial re-use for the construction of a noise attenuation berm the Town’s shooting range. Prior to the upland disposal/re-use of sediments, they were dewatered on-site by gravity means. The total cost of the project was $1.4 million.
The East Bay dredging project included the removal of 4,100 CY of fine-grained sediments to create a new Embayment Channel that provided access to the Town boat ramp. Sediments were hydraulically dredged by a local Contractor and dewatered using geotube technology within a containment area located at the adjacent parking Lot. Once dewatered, fine-grained sediments were trucked off-site and re-used as fill at the Robert Childs Wood Waste Reclamation Facility in Dennis, MA.
The project also consisted of the hydraulic dredging of 5,000 CY of beach quality sand from the existing Entrance Channel by the Barnstable County Dredge. Sediments were hydraulically dredged and pumped approximately two miles to Long Beach where they were spread and beneficially re-used for nourishment of the beach and dune areas. The total cost of the project was $1.3 million.
The Foth team has a well-established, proven track record working with the Town of Barstable on marine infrastructure, dredging, shoreline protection and site development projects. We have consistently demonstrated the ability to accomplish work tasks successfully, in a responsive and timely manner and within budget.
