The east jetty was completed to its project length of 25,270 ft and 
an elevation of +5 ft mlg using 44,370 tons of stone. 
The west jetty was raised and extended to its project length of 
21,860 ft and elevation of +4 ft mlg. A total of 27,860 sq yd of 
mattress and 178,700 tons of stone was placed. The approximate total 
cost for jetty completion was $860,000. As constructed, the jetties 
are slightly converging to an opening 1,800 ft wide at their seaward 
ends (Figure 2). 
Repairs were made to the jetties by adding stone and resetting 
existing cover stone. The 5,400 reset stones were to weigh a minimum 
of 2 tons each. A total of 67,700 and 26,100 tons of stone was 
placed on the east and west jetties, respectively. The east jetty 
repairs were carried out between sta 129+15 and sta 240+95. Costs 
and locations of west jetty repairs are unknown. 
The jetties were capped with concrete. The east jetty cap, placed 
from sta 183+67 to sta 253+10, had an elevation of 5.7 ft mlt and a 
top width of 10 ft. The west jetty cap was placed on the existing 
cap to an elevation of +4 ft mlt and an overall width of 10 ft. 
Stone totaling 23,130 tons and 15,070 cu yd of concrete were placed 
at a total cost of $608,000. 
The west jetty was repaired using 60,200 tons of stone at a cost of 
$834,800 (location of repairs unknown). Cover stone weighed 9 to 
13 tons each, and core stone weighed 25 to 200 lb each. 
Repairs were made from sta 60+00 to sta 183+67 and sta 68+00 to 
sta 179+50 on the east and west jetties, respectively (Figure 2). 
The east jetty was brought up to +7 ft mlt with a 9-ft crown width 
and 1V:1.5H side slopes. A similar cross section was used on the 
west jetty from sta 68+00 to sta 90+75 with the cover layer placed 
over the concrete cap. The remainder of the west jetty cap section 
was raised with core stone to +1 ft mlt, 1V:1.5H side slopes and 
covered with armor stone. The core stone varied from 25 to 200 lb. 
The cover stone varied from 4 to 13 tons between the landward and 
seaward ends of the repairs, respectively. A total of 430,000 tons 
(approximate) of stone was placed at a total cost of $3,961,000. 
No work has been done on the jetties since the 1960's, and they are 
considered to be in good condition, except for a 6,000-ft section at 
the west jetty's shoreward end.
