摘要：	A proposed bridge would connect mainland Currituck County, North Carolina, with the county's Outer Banks. The Outer Banks are rapidly developing with rental recreation homes. Cumulative impacts, particularly their secondary (indirect) impacts components, are one of the principal issues in deciding whether to build the bridge. The components of cumulative impact assessment represent an expansion of the traditional components of an impact assessment: scoping, description of the affected environment, and determination of environmental consequences and mitigation of effects. Scoping broadens to include past, planned, and unplanned induced governmental and nongovernmental actions and their effects, as well as a broader range of analysis limits. The affected environment encompasses a description not only of existing conditions but also of past trends, development and environmental goals, the project area's potential for growth, and forces of change. The assessment of environmental consequences looks at the incremental difference between the build and the no-build future. The absolute impact of both scenarios also is important because one might find that neither scenario is desirable. The components of cumulative impact assessment as derived from the literature and the application of cumulative impact assessment to the specific problem of the Mid-Currituck Sound bridge project are discussed.
