Contract value

$750,000

The solicitation does not disclose a contract value. Similar estuary restoration projects in Washington State for similar scope (creation/enlargement of breaches on a mid‑size island) typically range from $300,000 to $1,000,000 depending on site conditions, permitting, and contractor rates. Assuming modest earthwork, habitat design, and monitoring, a reasonable midpoint estimate would be around $750,000. This estimate accounts for engineering design, construction labor, equipment, and post‑construction monitoring, which are common line items in such environmental restoration contracts.
