Oak Orchard, New York 



Date(s) Construction and Rehabilitation History 



1975 Construction of parallel piers and a detached breakwater (Figure 278) 

 was completed at the mouth of Oak Orchard Creek. The east and west 

 piers were rubble-mound structures that were 670 and 900 ft long, 

 respectively. They had crest els of +8 ft Iwd, crest widths of 12 

 ft, and cover stones ranging from 3.5 to 7 tons with 50 percent or 

 more of the total stones weighing at least 4.5 tons (Figure 279). A 

 concrete walkway was also installed. The detached breakwater was 

 550 ft in length and of cellular steel sheet-pile construction. Cell 

 diameters were about 36 ft and included granular fill and concrete 

 caps (Figure 279). The crest el of the breakwater was +8 ft Iwd. 



1986 No record of maintenance to the structures is available, and they are 

 considered to be in good condition. An aerial view of the Oak 

 Orchard Harbor structures is shown in Figure 280.
