rubble-mound structure with a crest el of +10.3 ft Iwd and a crest 

 width of 10 ft (Figure 227, Section P, Figure 229, Section D) . Side

1904- Construction of the east and west arrowhead breakwaters was completed 

 1909 (Figure 226) at the main entrance. These structures were each 



1,250 ft long and constructed of rubble-mound materials. They had
