The alternatives selected to be carried forward from the previous step are further evaluated and screening in this step.  This further detailed analysis of selected alternatives includes an evaluation of the potential effects on the environment.  These findings, in addition to the findings from the previous steps, are reported in the Environmental and Engineering report.  The last step in this process includes further detailed technical and design evaluations associated with the alternatives, resulting in a recommendation of a preferred alternative. Public involvement and context sensitivity will continue to be applied throughout this part of the study.
