rubble-mound construction, with 1:1.5 side slopes, and it consisted 

 of 216,069 tons of stone. The seaward 1,700 ft had a crest elevation 

 of +19 ft mllw and a crest width of 26 ft; the rest of the jetty had 

 a +15-ft mllw crest elevation and a 20-ft crest width. Armor stone 

 was greater than 6 tons and averaged 10 tons.

rubble-mound construction, with 1:1.5 side slopes, and it consisted 

 of 462,767 tons of stone. The crest elevation was +19 ft mllw with a 

 crest width of 26 ft.

1966 The north jetty was rehabilitated, requiring an estimated 67,500 tons 

 of class "B" stone and 32,000 tons of quarry spalls and bedding mate- 

 rial. The class "B" stone was placed as an 8-ft-thick armor layer on 

 the underwater slope of the jetty in the damaged area, and it weighed 

 between 1 and 6 tons.
