general corrosion), except at their outer ends where scour and active
(cont.) soil pressures were evident, and the shoreline was eroding at the
landward ends. The cover stone size was determined from Hudson's
slope stability formula and a maximum depth-limited wave height of
12 ft. Existing elevations along the jetties varied from
to - 1 1
(seaward ends) ft
The rehabilation cost was 7,800 and
required 46,910 tons of stone.
1971
Riprap stone (0.5 in. to 200
was placed on the north jetty land-
ward end. The shoreline had eroded leaving a gap of approximately
50 ft. A total of 600 tons of stone was placed at a cost of about
Except for general deterioration (corrosion) at several locations of
the exposed sheetpiling, the jetties were considered to be in good
condition (visual inspection). The present overall lengths of the
north and south dikes are 2,300 and 2,250 ft, respectively.
