Construction and Rehabilitation History
700-ft section was repaired on the south jetty. A total of
45,000 tons of stone was placed, and additional stone was reset
(200 pieces) at a total cost of 2,000.
A historical synopsis written at this time (which did not describe
the condition of the jetties) stated that "the structure has served
the purpose for which it was originally constructed." Repairs were
made to the north revetment in 1948.
At the shoreward end of the north jetty, a 1,200-ft-long section was
made sand tight in conjunction with beach renourishment north of the
jetty. The modification required raising the crest elevation,
rebuilding damaged sections, and chinking voids with small stone (no
details). This modification would inhibit the l o s s of sand placed
adjacent to the jetty during, and subsequent to, beach nourishment.
The cost of the modifications was 8,000.
Presently a 38-ft-deep by 400-ft-wide channel is maintained between
the jetties. Except for the sand-tightened portion
jetties have not been repaired since 1934 and, although in poor con-
dition, are still functioning properly.
