Construction and Rehabilitation History 



1986 



Construction of two rubble-mound breakwaters was completed (Fig- 

 ure 262) . The north breakwater was 600 ft long with a crest el of 

 +12.5 ft Iwd and a crest width of 11 ft (Figure 263). Side slopes 

 were IV: 2H, and armor stone ranged from 2 to 5 tons. The south 

 breakwater was 1,850 ft long and included armor stone that ranged 

 from 4 to 9 tons. It included a +12.5 ft Iwd crest el, a 13.5-ft 

 crest width, and 1-V:2-H side slopes (Figure 263). The cost of con- 

 struction was about $6.1 million, which included a 550-ft-long berm 

 attached to the north breakwater (Figure 262). The breakwater con- 

 figuration was model tested prior to construction (Bottin and Chatham 

 1975). 



No maintenance repairs have been performed, and the structures are in 

 good condition. An aerial photo of the Cattaraugus Creek breakwaters 

 is shown in Figure 264.
