As part of improvements which included a small-boat harbor, a 600-ft-
l o n g rubble-mound jetty was constructed on the east side of the
Andrews River mouth (Figure
The design cross section (from a

mlw crown elevation, a 5-ft crown width, and
side slopes.
The section was to be built on a
blanket of 0- to 50-lb
stone, followed by a core of 1- to 300-lb sand tight quarry stone,
and covered with 400-lb to 1-ton armor stone. Cover stone at the
outer end was 1 to 2 tons. A total of 2,750 tons of stone was placed
for a total cost of ,700.
The 655-ft-long west jetty and 54 ft of wing wall were constructed
1973
using a total of 5,280 tons of stone for a total cost of ,400.
The design cross section was probably identical to the east jetty
section (based on 1966 DPR). Stone sizes were similar to the east
jetty sizes, except that larger 1- to
stone was not used at the
seaward end.
Visual inspection indicated the jetties were in excellent condition.
