Lorain Harbor Maintenance Dredging - 404(a) Public Notice

The attached map (Figure 1) shows the authorized limits and depths of the federal navigation channels. To ensure that minimum authorized depths in these channels are maintained throughout the shipping season and to account for dredging tolerance, an additional one foot of sediment may be removed. An estimated total of approximately 100,000 cubic yards of sediment would be dredged from the Lorain Harbor federal navigation channels annually.
