Based on the analysis of potential environmental, social and land use impacts the preferred alternative that satisfies the projects purpose and need can be selected. Once selected, refinement of approaches to minimization impacts can be completed. The preferred alternative considering habitat fragmentation, may or may not be the preferred NEPA alternative. The identification of potential mitigation options can also be conducted during the alternatives analysis process, but the final selection and evaluation of solutions is often completed following the identification of the preferred alternative and is discussed in the next section.
