Construction and Rehabilitation H i s t o r y
1963
Construction of two rubble-mound jetties at the site (Figure 17)
was completed along with dredging of channels and a turning basin.
The east and west jetties were 850 and 1,125
long, respectively,
to +16
mllw. Side slopes
with crest els ranging from +12
on the channel side and
on the bay side of the
were
jetties. Both structures were rubble mound with 3- to 15-ton armor
stone. The outer half of the west jetty on the bay side is pro-
quadripods. An aerial photograph of

The west jetty was sealed in an effort to minimize shoaling in the
1983
channel. This sealing was not very effective, and dredging re-
quirements were excessive following storms of 1983. A fixed sand
bypassing plant has subsequently been authorized and constructed.
The Santa Cruz Harbor District and the CE purchased (through cost
sharing) a dredge to maintain the harbor entrance. The Harbor
District is now responsible f o r maintenance dredging.
The jetties are in good condition, and there are no records of
1986
jetty maintenance since their construction.
