Description

Project DescriptionThe Contractor will be responsible for selecting the appropriate dredging technique and placement of the dredge spoils in the sediment placement area which may include a suction dredging method and a pump and hose method to transport the sediment to the Sediment Placement Area. In order to prevent the migration of suspended sediments outside of the sediment removal areas, Contractor shall provide and install a containment boom with a floating surface device, skirt, and longitudinal support prior to dredging activities. The containment boom will be located immediately outside the limits of each sediment removal zone and will be anchored to the shoreline. The skirt will extend to the bottom of the pond. The containment boom will remain in place during all dredging activities and be routinely inspected by the Contractor to ensure it is functioning properly. NOTE: No work shall take place in the areas with wetlands present until a wetland permit is secured by the County.NOTE: Erosion Control Plans are currently under review with GSWCC at the time of this bid. EC Plans may be adjusted based on comments received from GSWCC.
