D ate(s) Construction and Rehabilitation History 



1981 Erosion at the root of the north jetty required placing stone over a 

 375-ft section of the existing jetty beginning 125 ft from landward 

 end. The repair cross section consisted of a 1.5-ft layer of 1- to 

 50-lb bedding stone, a core of 30- to 1,000-lb stone, and 0.5- to 

 2-ton capstone. Side slopes were IV: 2H with a 5-ft crest width and 

 crest elevations varying from +9 to +12 ft mlw. Additionally, 

 1,150 tons of bedding stone, 1,970 tons of capstone, and rearrange- 

 ment of stockpiled core stone were used in the repair. 



1982- The north jetty weir section was closed using core and armor stone 

 1983 (no details) . Armor stone size and cross-section geometry were 



similar to those for the existing rubble-mound section at the sea- 

 ward end of the weir section. 



1985 The jetties are presently in good condition except for some damage 

 on the north jetty head because of a recent storm and continued 

 erosion at the root of the jetty.
