Abstract: A multi-objective criteria analysis was used to identify a proposed rail spur route with the optimal combination of low environmental impact, favorable engineering characteristics and economic feasibility. In Phase I of the three-phased alternatives analysis, 17 corridors were developed based on preliminary routing criteria defined by desirable environmental and socioeconomic features and engineering design constraints. In Phase II, the corridors were evaluated and ranked based on weighted environmental, socioeconomic, and engineering factors, in order to reduce the alternatives to four routes. The Phase III reanalysis of the top four routes included more detailed engineering studies and route modifications to further reduce potential impacts and project costs. Ultimately, the analysis was effective in distinguishing the least damaging, practicable alternative based on cost, logistics, existing technology and environmental impacts.
