Date(s) Construction and Rehabilitation History 



1964- main and east shore arm breakwaters were in poor to very poor condi- 

 1978 tion with numerous deficiencies in cross section, and there were 

 (cont.) significant amounts of displaced stone on the harbor side of the 

 structures at several locations. 



1983- The east shore arm breakwater was repaired, and the main breakwater 

 1984 repairs were started but were not completed due to contractual 



difficulties. The east shore arm repairs were made using 12- to 15- 

 ton stone and resetting existing stone. The majority of the repairs 

 were located on the seaward half of the breakwater from 10+50 to 

 20+30. The breakwater was rebuilt to a +10 ft mlw crown elevation, a 

 20-ft crown width, and slopes of 1V:2H and 1V:1H on the sea side and 

 harbor side, respectively. The cost of repairs was $702,500 for 

 20,275 tons of new stone and $81,870 for resetting existing stone. 

 The incomplete main breakwater repairs were identical to the east 

 shore arm repairs in stone weight and cross section geometry, except 

 for the side slopes which were 1V:1.5H from 0+00 to 20+34 and 1V:2H 

 from 20+34 to 67+25. The contract, awarded in the amount of 

 $2,275,000, called for placing 57,600 tons of stone and resetting 

 existing stone.
