| 摘要： | 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 transplanting of displaced eelgrass, clamshell dredging, and timing of dredging to minimize impacts to fishery resources. First cost of the project is estimated at $1,348,000 (October 1983 price levels with $226,000 allocated to the federal government and $1,122,000 allocated to local interests, based on distribution of benefits as national vs. local in nature. Whatcom County is the local sponsor. |
