Construction and Rehabilitation History 



As part of improvements at Chatham Harbor, a 200-ft-long rubble-mound 

 Jetty was constructed on the west side of the entrance channel (Fig- 

 ure 29). The armor stone was approximately 0.5 to 2 tons in size, 

 and the core stone varied from to 500 lb (cross-section details not 

 known). The cost for placing an estimated 1,375 tons of stone was 

 $13,750. 



The Jetty was extended approximately 300 ft landward via rubble-mound 

 and stone revetment. Erosion of the adjacent shoreline had resulted 

 in flanking of the jetty's inshore end. The rubble-mound section was 

 built using 0.5- to 2-ton cover stone and 0- to 50-lb core stone. 

 The contract cost for placing 945 tons of stone in the extension was 

 $12,950. 



Visual inspections indicated the jetty was in excellent condition. 

 1986 The present condition of the jetty is not known.
