Screening Alternatives
Impacts
Variants of Screening
Alternatives
• Establish rail and road criteria• Identify existing conditions• Develop cursory design of alternatives
• Identify impacts and constraints• Bring results to community
• Identify feasible alternatives• Develop variants to minimize impacts• Engage community for input
