plans will be identified, and screened or refined through the planning process, Projects
must be formulated to reasonably maximize benefits to the national economy, to the
environment, or to the sum of both, although locally preferred plans will also be
evaluated. Appropriate mitigation of any adverse effects will be an integral component
of each alternative plan that survives screening.

6.5 Evaluating Alternative Plans. The evaluation of alternatives is a comparison of the
future without-project condition and the future with,project condition for each
alternative,

In summary, the major tasks are:
-Screen potential solutions to reduce flood damages and improve the ecosystem to
determine those that are most feasible and documenting those that do not warrant
further consideration, and
-Evaluate effects of alternative plans (assesses effects of each plan to the without-
project condition,

6.6 Comparing Alternative Plans. Plans, including the no action plan, are compared
with each other during this phase, with emphasis on the outputs and effects that will have
the most influence in the decision making process. Both the beneficial and adverse
effects are compared, The comparison step can be defined as a reiteration of the
evaluation step, with the exception that in this step each plan is compared against each
other and not against the without-project condition. The output of the comparison step is
a ranking of the plans, In summary, the major tasks are:

-Compare alternative plans (focus on differences between plans such as cost,
flood damage reduction benefits, benefits to the environmental and other resource
effects, etc,);
-Identify the National Economic Development (NED) plan (the plan that provides
the maximum net annual economic benefits to the nation);
-Identify the locally preferred plan if different from the NED plan;
-Select a plan (based on evaluation and comparison of alternatives); and
-Prepare a draft feasibility report that documents problem identification,
formulation and evaluation of alternatives, and the selection and recommendation
of a plan( s).

6.7 Selecting a Plan.
The final step is the selection of a recommended plan from all those that have
been considered, The recommended plan must be shown to be preferable to taking no
action or implementing any of the other alternatives that were considered. The
culmination of the planning process is the selection of the recommended plan or the
decision to take no action,

6.8 Review and Approval. The final aspect of the Feasibility Phase is the review and
approval of the feasibility report, Initially, an internal draft feasibility
