respectively, both sections terminating at the seaward end. The 300- 

 Ib to 2-ton stone was placed to +3 and +5 ft mlg on the sea and 

 channel sides, respectively, with a berra width of 3 ft and 1V:1.5H 

 side slopes. A total of 38,300 tons of stone was placed at a cost of 

 $264,000. 



Two sections of the east jetty were repaired and a 100-ft-long jetty 

 tie-in constructed. A 650-ft section of the concrete cap, located 

 about 5,400 ft from the seaward end, was buttressed with stone. The 

 design geometry was identical to that used in 1966 repairs 

 (Figure 10). A 300-ft section and tie-in section, located 6,900 and 

 8,500 ft from the outer end, respectively, were built up to +7.5 ft 

 mlg, with a 6-ft crown width and 1V:1.5H side slopes. The repairs 

 were made with 300-lb to 2-ton stone, and a 1-ft-thick layer of shell 

 was placed as bedding for the Jetty tie-in. A total of 16,500 tons 

 of stone and 500 cu yd of shell was used for an approximate total 

 cost of $164,000. 



No new work has been done since 1971, and the project has been 

 essentially inactive since 1978. All deep-draft traffic now uses 

 Southwest Pass. Figure 1 1 is a 1977 photograph of the east jetty.
