than six feet measured from center to center (Diagram 2).
D. All walers shall be through bolted to each piling
and at the midpoint between pilings (Diagram 2).
E. The top waler shall be in line and joints shall be
either lap joints (Diagram 3) or plate joints (Diagram 5).
F. There shall be a minimum of three walers evenly spaced
and not less than 10 feet from the top surface of the top waler to

G. The middle and bottom walers may be stagger lapped
with each end extending no less than six inches beyond the bolt in
the piling (Diagram 4).
H. Sheeting shall extend from the top of the bulkhead
to a point no less than eight feet below mean sea level (Diagram 1),
and each board shall be securely fastened to each waler with no less
than two nails of adequate size.
I. When two layers of two-inch sheeting is used, the
second layer shall be installed in a manner to provide the maximum
cover of each joint in the first layer (Diagram 3).
J. Where a bulkhead is constructed to join an existing
bulkhead, the joint shall be made sandtight from the top of the bulkhead
to mean sea level.
K. All walls of bulkheads shall be anchored as shown
on Diagram 1.
L. One anchor piling shall be set for each face wall
and return wall piling.
M. Anchor piling shall not be set closer to the bulkhead
piling than 10 feet (Diagram 1).
N. A continuous horizontal member (deadman), no less
than two inches in thickness and 10 inches in width, shall be installed
extending the full length of the bulkhead face wall and return wall
and connected to the anchor piling by through bolting with the anchor
rod (Diagram 1).
O. An anchor rod shall extend through from the rear face
of the anchor piling to the front face of the bulkhead piling but
