A 450-ft-long rubble-mound breakwater was constructed (Figure 6) 

 using 9,080 tons of stone for a total cost of $11,800. 



1934 Repairs were made to the structure. Details of the work are not 

 known. 



1961- The breakwater was rehabilitated using 5,930 tons of stone at a cost 

 1962 of $103,000. The repair geometry (Figure 6, inset) had 1V:1.5H side 



slopes, a 10-ft top width, and a +18 ft mlw crown elevation. 



Seventy-five percent of the stone by weight was a minimum of 10 tons, 



and the remainder was a minimum of 3 tons. The cover stones weighed 



a minimum of 10 tons. 



1967- Inspections indicated the breakwater was in good condition with some 

 1977 displacement of cover stone on its seaward face.
