Effects of Norfolk Harbor Deepening on Management of Craney Island Disposal Area

摘要

Three alternatives for using Craney Island Disposal Area (CIDA) during deepening Norfolk Harbor are evaluated. Alternative 1 considers CIDA in its present configuration; Alternative 2 assumes CIDA is subdivided and managed as recommended in the CIDA Management Plan (Palermo, et. al., 1980) throughout the deepening project; Alternative 3 requires the construction of an expansion to contain all or part of the new work and maintenance volume dredged during the deepening project and requires the development of the existing disposal area as suggested in Alternative 2. Recommended: Combination of alternatives 2 and 3. Keyword: Dredged material containment.
