This emergency project was necessary to slow very rapid erosion of the River Right Bank of the Lower Satsop River, which was destroying high-quality farmland and threatening a home. While a long-term program of erosion and habitat improvements is underway on the Lower Satsop, an immediate solution was needed prior to the 2021/2022 flood season.

Washington State Department of Transportation (WSDOT) needed to remove state-owned culverts that block habitat for salmon and steelhead by 2030. The new culverts are larger and more resilient to changes in the landscape. Removing a single barrier can improve fish access for miles.

The Washington State Department of Transportation (WSDOT) completed a corridor planning study of I-5 between SR 121 in Tumwater and Mounts Road near DuPont to develop mid- and long-term strategies for improving the region’s transportation system. Strategies identified during the corridor study were further refined in the Planning and Environmental Linkages (PEL) study led by

Parametrix provided advisory services and change management support for WSDOT’s first GC/CM project—the Washington State Ferries (WSF) division’s reconstruction of its occupied flagship ferry terminal. The project is a joint undertaking of WSF and the King County Ferry District because it involves the simultaneous work for the collocated passenger-only ferry terminal facility. Parametrix helped WSF

The North Satellite modernization project expanded and renovated the 44-year-old facility to better serve passengers and respond to continuing growth at Seattle-Tacoma International Airport.
