Army Corps. of Engineers to Rebuild Willapa Dune
During dredging, crews will trawl the borrow site to determine Dungeness crab population density. Crews will return to the area next year and add empty oyster shells to the subsurface as a mitigation measure to create habitat and help repopulate the area more quickly.
Once the berm is reconstructed, the crest and landward side will be planted with American dune grass as an erosion control measure.
This portion of the two-phase dune restoration project is expected to be complete by late October. The next phase, ecosystem restoration, is scheduled to begin in 2014, allowing time for earthwork to settle.
“We want to give the area a couple of years to settle in, see how things change behind the berm, what processes take over, and then we’ll look at what we want to do for the restoration effort,” Jackson said. In addition, the berm will need to be renourished about every five years, dependent upon storm damage.
The Corps consulted with U.S. Fish and Wildlife Service and the Washington Department of Fish and Wildlife on critical habitat needs for plover. Throughout the planning process, the Corps also coordinated with the Bureau of Indian Affairs, National Oceanic and Atmospheric Administration, Washington Department of Parks and Recreation, and the Department of Natural Resources.
