Construction and Rehabilitation History
Construction of a 620-ft-long north pier and a 790-ft-long south pier
1909
(Figure 152) was completed by private interests. The north pier is a
stone-filled timber crib, and the south pier consists of stone-filled
timber cribs and steel sheetpiling with concrete caps. The outer end
of the south pier is a 20-ft semicircular steel sheet-pile cell with
a concrete cap.
1971
Maintenance of the project by the Corps was authorized. Maintenance
of the piers prior to this time was performed by private interests
and the Michigan Department of Natural Resources.
Riprap stone was placed along and into the water along 4 9 0 ft of the
1973
north pier which was in a very poor to failed condition.
Fill stone was placed in the steel sheet-pile cell at the head of the
1983
south pier, and riprap stone was placed around and on top of the
cell. A 35-ft breached area and a
breach near the shoreline
of the south pier also were repaired with
and riprap stone.
An inspection of the site indicated settled and/or washed out stone
1985
in numerous areas of the north pier. Water is washing through the
voids of the structure, and three areas are nearly breached. The
steel sheet-pile cell at the head of the south pier is completely
broken out, and most of the grout cap along the entire length of the
pier is missing with stone being washed out. The condition of the
piers is very poor, and
