Water and Related Land Resources Management Study. Volume VII. Effect Assessment Appendix.

摘要

Effect assessment and evaluation provides information to the planning process that will aid in the acceptance, reformulation, or rejection of alternative plans. The purpose of effect, or impact assessment is to identify and measure the economic, social, and environmental changes from the base conditions that are expected to result from alternative plans. The purpose of evaluation is to determine how well the alternative plans achieve the planning objectives and how the plans affect other related problems. Evaluation requires public values to measure the relative significance of the impacts. The net result of impact assessment and evaluation should be the presentation of information in sufficient detail to permit the selection by decision makers of alternatives that contribute the most to local, regional, and national objectives and at the same time, minimize adverse actions in any area.
