Port of Everett commissioners approved an extra $337,000 to pay to remove sediment from the marina -- that's on top of the $888,500 originally approved.
That's because the contractor, Pacific Pile and Marine of Seattle, found nearly double the sediment than first predicted -- 37,000 cubic yards, up from 20,000.
That's the equivalent of 3,700 dump truck loads of sand, silt and other debris.
The marina is on the Snohomish River channel. A roiling mass of slurry comes down the river and ends up settling along the bottom of the marina, said Port of Everett chief engineer John Klekotka.
It's left at least a few deep-draft sailboats stuck in the muck during low tides.
About once a decade, the port pays a contractor to dredge out the muck, which is disposed of at a special site offshore in Port Gardner.
The contractor started work in December, dredging the area between the north visitors dock to Dock C in the north marina.
Workers found far more sediment had accumulated than expected, particularly around the marina's fuel dock.
The work was expected to be completed last weekend.
