Budget estimate

$10,000,000 – $20,000,000

Based on typical dredging costs of $30‑$50 per cubic yard, the base volume (376,000 CY) would represent roughly $11 million to $19 million in labor, equipment, and material placement. Adding the optional 75,300 CY (if bid) could increase the total to $14 million‑$24 million. Considering mobilization, environmental monitoring, and contingency allowances, a realistic award range is estimated between $10 million and $20 million.
