Intracoastal Waterway dredging about to begin

Ahtna Marine & Construction Company, LLC, of Pompano Beach, Florida, is about to begin dredging silt from the Intracoastal Waterway (IWW) in St. Johns County.

According to the Corps, the contractor will start dredging sections of the IWW within the Palm Valley North Reach in October 2021 with the completion set for May 2022.

This $7.8 million worth O&M dredging contract that was awarded Aug. 20, 2021, to Ahtna Marine will address problematic shoaling within this reach of the IWW. The contract is being funded with a combination of federal funds and contributed funds form the Florida Inland Navigation District.

The Palm Valley North Reach will be a large operation and maintenance dredging project, with 641,500 cubic yards of material being removed from the channel.

The material will be placed in the existing Dredge Material Management Area (DMMA DU-9), located in Duval County at the north end of the project area.

Dredging will begin at the Duval-St. Johns County line and continue southward to the Palm Valley Bridge.
