FEAS is a planning study to determine the viability of proposed improvements through evaluating possible alternatives, and the potential economic, social, and environmental impacts. Authorized activities for these projects include design concepts, general ROW requirements, alternative project solutions, traffic analysis, environmental fatal flaws, and planning-level cost estimates.

FEAS is outside the scope of PLAN Authority and doesn't require any of the three level authorities. The associated “construction costs” of feasibility studies represent the cost of the study.

TPP Corridor Planning Coordinator approves projects in FEAS Authority. FEAS Authority ends at the completion of the feasibility study.
