Budget estimate

$50,000 – $150,000

Based on typical municipal culvert design contracts, a small‑to‑medium scale culvert rehabilitation design package in Maine usually ranges from $50,000 to $150,000. The lower end reflects a limited number of culverts and straightforward permitting; the higher end accounts for multiple structures, complex hydraulic analyses, and detailed permitting packages. Factors influencing the final amount include the number of culverts, site access conditions, required hydraulic modeling, and any supplemental environmental review.
