Abstract : Conducted under Section 107 of the 1960 River and Harbor Act, as amended, the Corps of Engineers study determined the feasibility of federal involvement in constructing a navigation access channel and other improvements to service a proposed public commercial fishing boat marina at Lummi Day in northwestern Washington. Principal features of the tentatively recommended plan are (1) a moorage basin for 438 commercial fishing boats with floats, docks, etc., and a public boat launching ramp for small boats to be built by the Lummi Indian Tribe behind a diked portion of their existing aquaculture pond project; (2) federal navigation channel, 7300 feet long by 100 feet wide by 12 feet deep at mean lower low water with timber pile breakwater protection at the moorage basin entrance and a turning basin and local access channel; (3) disposal of approximately 1,470,000 cubic yards of material from channel and moorage basin dredging behind containment dikes to provide 65 acres of fill for marina support buildings and other water-related development by the Lummi Tribe; (4) mitigation for project-related impacts to shallow-water habitat by reintroducing 65 acres of the existing sea pond project not now in use for aquaculture to tidal action and preserving the portion as an undeveloped tidal area with establishment of wetland marshes and planting of eelgrass in selected areas; (5) maintenance dredging of channels and moorage basin with disposal of about 2 to 3 acres of dredged fill every five years at a 25-acre site within the unused sea pond.
