Browns Creek Jetties 



Sayville, New York 



New York District 



Date(s) Construction and Rehabilitation History 



1892 Two riprap jetties were constructed east and west of the creek en- 

 trance. The east jetty was 448 ft long, and the west jetty was 492 ft 

 long (Figure 20). Crest elevations were +1.0 ft hw, crown width 

 was 3.0 ft, and side slopes were 1:1. The minimum stone used was 

 500 lb. 



1927 The west jetty was repaired and extended 208 ft (Figure 20). Eleva- 

 tion of the extension was +3.0 ft hw. Nine hundred eighty one cubic 

 yards of rock was used for repair and extension. 



1935 The outer 213 ft of the west jetty was repaired. Minimum capstone 



and slope stone was 2.0 tons, and core stone was 15 lb to 1.5 tons. 



The crest elevation was raised over the entire jetty to +4.0 ft mlw, 



crown width was 4.0 ft, and side slopes were 1V:1.5H. 



1962- A survey indicated the jetties were deteriorated. Almost all stones 

 1963 were displaced on the west jetty, and there were numerous openings in 

 the structure. Most of the stones were shifted out of place on the 

 east jetty. Almost half of the jetty was breached and was not visi- 

 ble at mean low water. The jetties were rehabilitated over the en- 

 tire lengths in 1963 using 4,000 tons of stone at a cost of $71,000. 

 Crest elevations were +4.0 ft mlw, crown width was 6.0 ft, and side 

 slopes were 1V:1.5H (Figure 20). Three-ton cap and slope stone, and 

 15-lb to 1.5-ton core stone was used. The design wave was 5.0 sec, 

 6.0 ft. 



1986 No further repair or maintenance information has been found. The 

 project has been deauthorized.
