Construction and Rehabilitation History
The jetties were inspected after the August passage of Hurricane
Celia. Displaced cover stone was noted at the seaward end of the
north jetty (the convex portion of the north jetty's channel side)
and a section of the south jetty's gulf side adjacent to and seaward
of the existing shoreline. It was not known how much of the existing
damage was caused by Hurricane Celia since no repairs were made
subsequent to Hurricane Beulah.
The jetties were repaired by adding and resetting cover stone on
damaged sections noted during the
inspection (see above).
Repair areas on the north jetty channel side included 10 sections
where 1 - to
12-ton stone was added and the displaced
to 10-ton stone reset.
At the north jetty seaward end displaced 16- to 18-ton stone were
reset along 300 ft of channel and head semicircle side slopes. The
south jetty's gulf side between
(existing shoreline) and
was repaired by adding
to 6-ton stone, and its channel
side was repaired between
by adding 1,000- to
4,000-lb riprap stone. Total cost of the repairs was 9,500.
Seven sections of the south jetty totaling 980 lin ft between
were repaired by placing stone on the landward
side of the concrete cap. Scour beneath the cap had caused piping
and removal of sand along its landward face. Although this condition
had existed for several years, repairs were considered necessary due
to the size of the scour holes and concern for human safety. The
repairs consisted of placing a 1.5-ft-thick bedding layer of 0.5- to
extending 12 ft from the cap and covered with a 2.5-ft
thickness (but not to project above the cap) of 200- to
riprap extending 8 ft from the cap. Total cost of the repairs was
The jetties were inspected and considered to be in good condition
with the exception of 10 to 20 cover stones that were displaced along
the channel side of each jetty's head section, displaced cover stone
along the north jetty channel side, and settlement of some supporting
stone beneath the concrete caps.
