Budget estimate

$1,000,000 – $2,000,000

Based on comparable river‑bank stabilization contracts in the Mountain West, a project of this magnitude (approximately 1‑2 acres of riverbank, multiple structural elements, and vegetative restoration) typically ranges from $1 M to $2 M in total construction cost. The estimate accounts for heavy equipment mobilization, specialized labor, material (riprap, timber, boulders, willow), engineering oversight, and bonding/security requirements. Local labor rates in Wyoming and the relatively short construction window (≈ 6 months) keep the upper bound near $2 M, while a streamlined scope could be executed closer to $1 M.
