PROJECTS

Lower Dungeness Levee Setback & Floodplain Restoration

CLIENT Clallam County

Location Clallam County, WA

The Lower Dungeness project involves 2,500-foot-long, river levee setback, roadway relocation and 120-acre river floodplain restoration. 

As prime consultant, Shannon & Wilson is leading the project design team for design, permitting, and construction phase engineering services. The work includes fluvial geomorphology, multidimensional (2D) hydraulic modeling, erosion and scour protection, groundwater studies, sea-level-rise and climate change analysis, drainage studies, roadway reconfiguration designs, geotechnical stability analyses, and seismic analyses.

We are collaborating with Clallam County and the Jamestown S'Klallam Tribe, US Army Corps of Engineers, Washington Department of Fish and Wildlife, and the Washington State Department of Transportation in developing a restoration design that restores functional river floodplain and channel migration zone, while addressing potential project impacts and community concerns.
