Marina Dock Age

Hagadone Hospitality received its federal permit in April to begin renovating the Marina Yacht Club on Blackwell Island in Coeur d’Alene, Idaho, according to a April 13 report from The (Spokane, Wash.) Spokesman-Review.

After the expansion, the marina will have 420 slips, new offices, and higher ground for future residential development. The work will take place over six years but must occur during low-water periods in fall and winter, said John Barlow, a Hagadone Hospitality executive.

The company will dredge 142,000 cubic yards of material from the lake bottom, depositing clean material on Blackwell Island. The 18,000 cubic yards tainted with heavy metals from upstream mining activity will be taken to a landfill.

Environmental groups objected to Hagadone Hospitality’s earlier plans to dispose of the tainted soil in lined pits on the island. In January, company officials agreed to take that soil to an offsite landfill.
