Construction and Rehabilitation History 



Three rubble-mound breakwaters were constructed as part of the Harbor 

 of Refuge at New Haven (Figure 47). The breakwaters were constructed 

 to a crown elevation of +12 ft mlw, a 12-ft crown width, and slopes 

 of 1V:1H and 1V:1.5H on the harbor and sea sides, respectively. The 

 3,450-ft long east breakwater was built during 1880-90 using 

 293,800 tons of stone and repaired in 1911 using 2,900 tons of 

 stone. The 4,500-ft-long middle breakwater was built during 1891-96 

 using 339,000 tons of stone and repaired in 1911 and 1915 using 

 10,600 and 12,000 tons of stone, respectively. The 4,200-ft-long 

 west breakwater was built during 1896-97 and 1907-11 using 

 478,100 tons of stone and repaired in 1915 using 14,300 tons of 

 stone. The breakwater's construction costs during this period were 

 approximately $ 1 , 1 20 , 000 . 



The breakwaters were repaired using 6,720 tons of stone for a total 

 cost of $18,500. 



The breakwaters were considered to be in fair to good condition 

 during several visual inspections taken over this period. 



Yearly visual inspection of breakwaters indicated they were in good 

 condition. .
