How much does it cost to dredge around my dock?

Dredging around and beneath a dock is possible.  You should check the water depth from the main body to the dock to make sure that adequate depth is present past your boat dock as well.  Dredging costs vary signicantly depending on the type of dredging and amount of volume of silt to remove.  Usually, dredging costs are $20 to $50 per cubic yard.  Most docks require at least 100 cubic yards of sediment to be removed to make a significant impact on depth.
