Lorain Harbor Structures
Construction and Rehabilitation History
Construction of two stone-filled timber crib piers was completed at
the mouth of the Black River (Figure 219) during this time. The east
pier was originally 1,875 ft long, and the west pier was 1,004-ft
long. The east pier was 20 ft wide, and the west pier ranged from 17
to 23 ft wide (Figure 220).
west piers were capped with concrete superstructures
The crest els of the piers were
Construction of two detached rubble-mound breakwaters (Figure 219)
was completed. The east and west breakwaters were 2,300 and
2,811.5 ft: long, respectively. The structures had crest els of
ft lwd and crest widths of 1 ft. Side slopes were
on the harbor side. Armor stones used were

The west breakwater was extended to shore (Figure 2 9 .
rubble-mound construction and originated at the shore end
of the existing west breakwater extending shoreward 438.5 ft. At
this point there was a 75-ft gap and then a 750-ft-long extension to
the shore. The structure had a crest el of
ft lwd with a width
of 5 ft (Figure 220). Armor stone was 2 tons (minimum).
Construction of a 2,457-ft-long east breakwater shore arm (Fig-
ure 219) was completed at a cost of about .7 million. The outer
2,323 ft was a granular-filled concrete capped cellular steel sheet-
pile structure. The cells had a 35-ft diameter with a crest el of
mound shore connection (Figure 219). The rubble-mound portion had a
crest el of

The lakeward 995-ft portion of the east pier was removed leaving an
880-ft-long pier, and the lakeward 280-ft portion of the east break-
water was removed resulting in a structure 2,020 ft in length (Fig-
ure 219). A 2,180-ft-long granular-filled cellular steel sheet-pile
outer breakwater was constructed (Figure 219). Cell diameters were

of the rubble-mound

damage and consider-

in fair condition,
and no repairs are planned in the near future.
