EVALUATE EFFECTS OF ALTERNATIVE PLANS
The effects of the alternatives are found by comparing the alternatives with the objectives. An approach is to list the objectives and the alternatives along the columns and rows in a table, where the effects are described in the boxes. The effects can be a subjective scale such as: high, medium, or low, but whenever possible the effects should be quantified. The scale chosen to identify the effects from an objective must be consistent for all alternatives. For example, if the effect--for the objective of reducing damages from flooding--is described in dollars of annual benefits, then each alternative must be compared in dollars of annual benefits. During the evaluation of effects, it may become apparent that an effect is not attributable to an objective, thus the objectives must be revisited and revised accordingly. Effects can also be conceived of as consequences, and the consequences of an action will vary over time. When conceptualizing consequences, it may be helpful to visualize a time in the future when the alternative has been implemented. Thus, the short, medium and long-term consequences should be identified.
Many of the alternatives will be discarded at this point based on the effects, and a few superior alternatives may become apparent. If alternatives are dropped from further consideration , then it is very important to document the rationale. It is necessary to seek stakeholder input and consensus on to plan effects and this may result in revision of the objectives.
