Construction and Rehabilitation History 



A 470-ft armor stone breakwater extension was added to an existing 

 stub breakwater. The breakwater was part of a light draft harbor 

 project completed in 1965 (Figure 14). Total project cost was 

 $742,850. Along the breakwater's length the armor stone varied 

 from 2 to 4.5 tons for design breaking-wave height ranging from 

 3 ft at the root to 10.1 ft at the head. 



Recent inspection of the breakwater revealed only minor damage 

 that did not warrant immediate attention.
