Central Marina Dredging
#5 - Develop Sustainable Marina Operations
Project Location Map
The Port is implementing a maintenance dredging program over several years within the South and Central Docks Areas. The Port’s marinas slowly receive siltation from the Snohomish River, which requires maintenance dredging approximately every 10 years in some locations of the marina. As of September 2018, the Port has received all necessary permits for this endeavor. The South and Central Marinas have authorized draft of -12 to -14-feet at a zero tide (mean sea level). Depths in the South and Central docks range from -7 to -14 feet, so the areas that have filled in, are being dredged. The dredging is being phased in with dock improvements as possible, but general maintenance dredging will occur as well. The dredged material will be
disposed of under permit at the Port Gardner Bay open water disposal site, except for a small quantity of material that must be disposed of at a landfill.
Safe navigation for boaters.
