Project Specifications
Location: Conway, WA
Square Footage: 2.5 acres / 13 channels
Delivery: Bid
Removal and placement of approximately 30,000 cy of levee and channel material, grading, embankment, and rough restoration. Nearly 2.5 acres of levee were removed across 22 locations. The excavated material was used to form wetland habitat mounds which will be planted with native species to create scrub-shrub and forested tidal wetlands. The 13 new channel networks that were excavated totaled approximately 9,050 feet, creating blind tide channels and tidal headwaters. Four 30” culverts were also removed during the project and replaced with tide channels. These features help to restore the island for species like salmon, beaver, birds, and other wildlife.
