were bedded and covered in a sand-filled wooden
crib structure. The crib consisted of five longi-
tudinal continuous spread footings and vertical
planked division walls tied together with ribbons, planked over, and covered with earth fill.
Beginning at the second retaining wall and on
radial alignment with the T-duct and the work
point of Station 20, four runs of pipeline were
constructed. The pipelines terminated at a concrete retaining wall at the south side of Station
20. They were supported on a steel post and
beam with upright saddle detail supported on
three concrete spread footings at three of six
support frames. At three more closely spaced
pipe supports the lines were suspended from a
steel beam over two steel posts by adjustable
tie rods and adjustable horizontal tie rods. These
lines were also covered by earth-fill.

Station 1528.01 was in two parts. First,
a wood frame platform tower, 5-foot-square in
plan, 22 feet high, was located at the north end
of Site Yvonne near the high tide line. Tower
platform was at Elevation +27.21, The tower
was supported on an 8-foot-square by 16-inchthick re-inforced concrete spread footing. The
second part of this station was a wood-frame
baffle structure located approximately 500 feet
southeast of the platform structure. The frame
closely resembled a sign board and consisted of
two bolted, laminated 4x12 columns, the lower
ends buried 10 feet to support a 2x12 frame
sheathed with 4-inch plywood on one side between columns. The sheathed area was 12 feet
wide by 12 feet high with a 5-foot-wide by 2foot-clear opening at its geometric center. Top
level of this frame was at Elevation ~ 34.0, The
structure was painted two coats of blackboard
slating paint.
Station 1528.02 was also in two parts. First,
the wood-frame platform was only 2% feet
high above the top of a spread foundation slab
on top of a deep coaxial cable fill close to Station
20. Top of platform was at Elevation +27.17.
