Construction and Rehabilitation History
Construction of a 1,410-ft-long west pier (Figure 259, Section I) was
this time. The pier was constructed of concrete and
A concrete superstructure was installed on most of the west pier.
The maximum el of the superstructure was

line was constructed with large stone.

Construction of a 2,237-ft-long portion of the outer breakwater
was completed. The structure was 30 ft
wide and consisted of stone-filled timber cribs (Figure 260, Sec-

of a 1,200-ft-long west and 1,464-ft-long east break-
water (Figure 259) was completed during this period. The structures
were rubble mound with els of +11 ft lwd, crest widths of 10 ft, side
and armor stones ranging from 1,400 to 3,800 lbs.
The inner rubble-mound breakwaters presently are in good condition,
and the west pier and outer breakwater are considered to be in fair
condition. The concrete portions of the superstructure of the outer
breakwater and pier show signs of spalling and slight separation at
the joints; however, no immediate action is required. The stone
superstructure portions of the outer breakwater seem to have settled
lakeward in areas, and additional stone has been recommended to in-
crease the height of the structure to its original design. An aerial
view o f the Dunkirk Harbor structures is shown in Figure 261.
