Construction and Rehabilitation History 



Construction of a 1 ,350-f t-long west breakwater and a 750-ft-long 

 east jetty (Figure 284) was completed. The structures were built of 

 rubble-mound materials with crest els of +10 ft Iwd (Figure 285). 

 The trunk section of the east jetty had an 11-ft-wide crest width, 

 1-V:1.5-H side slopes, and 0.5- to 1.5-ton armor stone. The east 

 jetty head section and the shoreward arm of the west breakwater had 

 crest widths of 14 ft and armor stones ranging from 3.0 to 6.5 tons. 

 The head section of the east jetty had side slopes of IV: 2H. The 

 lakeward arm of the west breakwater included armor stone ranging from 

 7 to 15.5 tons and a crest width of 16 ft. Side slopes of the west 

 breakwater were 1V:1.5H, with the exception of the head which had 

 1-V:2-H slopes. An aerial view of the Irondequoit Bay structures 

 taken during construction is shown in Figure 286. (Note the channel 

 had not been dredged.)
