Chinook Marsh Restoration Project Design

The Snohomish County government is seeking qualified firms to develop the design for the Chinook Marsh Restoration Project. This effort will involve detailed engineering, ecological, and permitting work to restore and enhance the marsh habitat, providing flood mitigation and wildlife benefits. The work is scoped as a design‑only effort, requiring the preparation of construction‑ready plans, specifications, and supporting environmental documentation. • Deliver a complete design package (drawings, specifications, cost estimates) for marsh restoration. • Conduct site assessments, hydrologic modeling, and ecological analyses to meet state and federal permitting requirements. • Coordinate with county staff and provide technical support during the permitting process.
