damaged during a 1977 storm, the expanded section of the dock was closed dur- 

 ing the winter months. To protect the expanded dock area, the Corps con- 

 structed two short rubble-mound breakwaters during 1981 to 1983. A chronology 

 of events related to the development and repair of the harbor structures is 

 given in Table 2. 

 Douglas Small-Boat Basin, Alaska 



21. Douglas is located on Douglas Island, Alaska, across the Gastineau 

 Channel about 2 miles southeast of Juneau. The project, as adopted in 1958, 

 includes a 5.2-acre small-boat basin dredged to -12 ft mllw and a 90-ft 

 rubble-mound breakwater . 



22. The project was completed in 1962, including a 105-ft rubble-mound 

 breakwater. To maximize the area of the harbor, 1:3 side slopes were dredged 

 on the southeast and southwest sides of the basin. These slopes were covered 

 with a 2-ft filter layer of gravel under a 2-ft layer of quarry run rock for 

 slope protection. The other sides of the basin were dredged to 1:10 slopes 

 and did not require protection. A chronology of events related to the devel- 

 opment and repair of the harbor structures is given in Table 3. 



Haines Small-Boat Basin, Alaska 



23. Haines Small-Boat Basin is located on the west shore of Portage 

 Cove, adjacent to the City of Haines in southeast Alaska, about 90 water miles 

 northwest of Juneau, Alaska. The project includes the extension of an exist- 

 ing small-boat basin by removal of part of an existing breakwater and con- 

 struction of a 905-ft offshore rubble-mound breakwater. 



24. The existing small-boat basin was constructed by a joint effort of 

 the Territory of Alaska and Alaska Public Works, a one-time Department of the 

 Interior agency. The basin was protected by an 800-ft L-shaped breakwater 

 completed in 1958. The basin was intended to enclose a 2.5-acre basin dredged 

 to -10 ft mllw. Difficulties in dredging the basin resulted in only 1.8 acres 

 being completed. 



25. The Corps project was adopted in 1971 and included expansion of the 

 basin to 4.2 acres dredged to -12 ft mllw and -14 ft mllw, with an entrance 

 channel dredged to -15 ft mllw, removal of the seaward leg of the existing 

 breakwater, and construction of a 905-ft crescent-shaped offshore rubble-mound 

 breakwater. The project was completed in 1976. A chronology of events re- 

 lated to the development and repair of the harbor structures is given in 

 Table 4.
