Budget estimate

$300,000 – $400,000

The solicitation states an approximate budget of $350,000 for the full feasibility study, including design, analysis, public outreach, and deliverables. Considering typical professional‑services mark‑ups, contingency, and potential change orders, a realistic earnings range for the selected firm would be roughly $300,000 on the low end (if scope is tightly controlled) to $400,000 on the high end (if additional analyses or extensive public‑engagement efforts are required). Factors influencing the final amount include the depth of traffic and environmental studies, the number of public workshops held, and any required coordination with state or federal agencies.
