1983
breakwater was 300 ft long. Both breakwaters were constructed to a
crest elevation of +20 ft mllw, a crest width of 8 ft, and
side
slopes. The breakwaters were constructed with a core of quarry-run
rock covered by a filter layer of 150- to 1,500-lb rock, and an armor
layer of 2,200-lb rock with a range of 1,500 to 3,000 lb. The break-
water was designed for a significant wave height of 5 . 3 ft; the armor
rock was designed for the 10 percent wave height of 6.7 ft.
