Budget estimate

$2,000,000 – $5,000,000

No contract value is disclosed, but similar county‑wide environmental consulting awards for multi‑year scopes typically range from a few million to several million dollars. Assuming a moderate workload of several major projects over a 3‑4 year period, a realistic estimate would be between $2 M and $5 M in total fees. Factors influencing the range include the number of projects, depth of technical studies, hourly rates for senior staff, and any optional extensions.
