Cost: The total construction cost for this breakwater was $9,500 in 1979. 



This figure translates to a cost of $15.03/m 2 ($1.40/ft 2 ) in 1980 dollars. 



Benefits: The estimated annual savings in maintenance to the marina is $5,000. 

 The operator rated the breakwater as having a positive effect on 

 sport fishing and on drawing birds away from his facility and a strongly 

 beneficial effect on boaters' comfort. He also noted that the structure 

 improved upon waterfront appearance and water circulation over a 

 previously installed floating concrete and steel breakwater which had 

 disintegrated. The replacement cost of this rigid FB was estimated to be 

 in excess of $250,000. The operator also rated the breakwater as 

 providing excellent performance in suppressing waves, meeting design goals, 

 and satisfying his needs. Overall performance was rated excellent. 



Fouling Characteristics: A variety of marine life inhabits the structure 



including seaweed, seagulls, herons, other fishing birds, and muskrats. 



Project Analysis: While new with relatively little time for major problems to 

 develop, this FTB appears to be a classic success. One should note that 

 it is built according to the state-of-the-art, well maintained, and 

 installed where site conditions are suited for an FTB. Its 

 cost-effectiveness is especially dramatic in comparison with the previous 

 floating concrete and steel breakwater.
