Draft Detailed Project Report and Environmental Assessment, Sandy Point Navigation Channel, Whatcom County, Washington.

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 navigation improvements at the entrance to Sandy Point harbor on the Strait of Georgia in northwestern Washington. The project would reduce coastal shoaling and provide wave protection for recreational boats and commercial fishing boats navigating the entrance. The principal features of the tentatively recommended plan are channel enlargement to 1,200 feet long by 75-100 feet wide by 10 feet deep at mean lower low water; 2 rock breakwaters for deflection of sediments away from the channel and for protection of boats and shoreline properties from wave action; a rock revetment to prevent erosion at the channel entrance; advance maintenance areas to trap sediments and reduce frequency of channel maintenance dredging; initial dredging of approximately 60,000 cubic yards of sediments and disposal at the Department of Natural Resource-managed open water disposal site in Bellingham Bay; and mitigation for project-related impacts by transplating of displaced eelgrass, clamshell dredging, and timing of dredging to minimize impacts to fishery resources.
