Book excerpt: Dredging and disposal activities would have temporary adverse effects on water quality, organisms living in and on the bottom sediments in affected areas, aesthetics, recreational fishing, and the ability of the area to support aquatic life. Beneficial impacts of maintenance operations include continuance of the existing local economy through preservation of navigation-dependent commercial enterprises and through recreational benefits available to regional residents and tourists. Water quality may be temporarily impacted by several of the proposed activities. The impacts would essentially be limited to turbidity and the possible release of nitrogen compounds to the waters during dredging and disposal operations. Recreationalists may be temporarily inconvenienced. In addition to maintenance dredging by bucket or hydraulic pipeline dredge, other alternatives include: (1) discontinue maintenance dredging; (2) dredge the harbor to a lesser depth; (3) alternative dredge types; and (4) dredge only the critically shoaled areas. Implementation of the alternatives could cause economic or social impacts in the Bolles Harbor area. Alternatives to the proposed disposal methods are enumerated. The only true alternative to maintenance of structures related to the navigation project is to terminate maintenance.
