Construction and Rehabilitation History 



An existing rock fill breakwater with a concrete cap was improved 

 by widening the crown and armoring the structure slopes with 6.5- 

 to 12-ton armor stone (Figure 12). The armor stone was designed 

 for a 12-ft breaking wave in a water depth of 15 ft at the 

 breakwater head. The breakwater modification cost approximately 

 $95,000. As of 1984, the structure has required no major 

 maintenance.
