to 0 ft rnlw at
the existing structure showed elevations of from
the shoreward and seaward ends, respectively. Storm and wave action
was believed to be major cause of subsidence at the seaward end.
Seaward ends of jetties were in approximately 12 ft of water, and a
35-ft-deep channel passed between the jetties. The jetties were
approximately 1,200 ft apart at their shoreward ends and converged
at their seaward ends to a distance of 550 ft. The north and south
jetties were approximately 1,250 and 1,025 ft long, respectively.
Natural rock strata underlying the jetty and inlet areas exists at
-10 to -15 ft mlw.
Repairs made to the jetties consisted of placement of 2- to 10-ton
