The U.S. Coast Guard (USCG) has completed a Draft Environmental Assessment (EA) in support of proposed Maintenance Dredging at Coast Guard Station Cape Disappointment, Pacific County, Washington in compliance with the National Environmental Policy Act of 1969 (NEPA; 42 U.S. Code §§4221 et seq.) and the regulations of the President’s Council on Environmental Quality implementing NEPA (40 Code of Federal Regulations [CFR] Parts 1500-1508).
The proposed project includes dredging over a 10-year period to return and maintain depths at the mooring basin and travel lift areas at Station Cape Disappointment to previous operational depths of -10 feet (mean lower low water) MLLW and in-water or upland placement of dredged material. The Proposed Action allows for 2 feet of over-dredge depth within this footprint, bringing the dredge elevation -12 feet MLLW over a total dredged area of 4.2 acres which would result in the removal of approximately 3,726 cubic yards of sediment during the initial dredge event proposed to be conducted in 2021. Subsequent maintenance events would be conducted as needed to maintain operational depths within the 10-year period.
