Date(s) Construction and Rehabilitation History 



1981 Two parallel rubble-mound jetties were constructed to provide channel 

 control. Both jetties were 370 ft in length and spaced 120 ft apart 

 (Figure 71). Crest elevation was +5.0 ft ralw but allowed for 0.5 to 

 1.0 settlement; crown width was 5.0 ft; and side slopes were 1V:2H. 

 One layer of armor stone, 300 to 500 lb, was placed over one layer of 

 core stone, 3.0 to 40 lb. The jetties rested on a 2.0-ft-thick sand 

 blanket. The sand was encased by filter fabric. A 5.0-ft-wide, 

 1.5-ft- thick apron and a 5.0-ft-wide, 3.0-ft-thick apron were placed 

 on the shore and channel sides, respectively (Figure 71). A 6.0-sec, 

 4.1 -ft design wave was used. Estimated cost of construction was 

 $245,000. 



1986 No further repair or maintenance information has been found.
