Parsons Recognized for Excellence in Fish Engineering


CENTREVILLE, Va., June 18, 2021 (GLOBE NEWSWIRE) – Parsons Corporation (NYSE: PSN) today announced that the company’s Coffee Creek Fish Barrier Removal Project has received a National Recognition Award from the American Council of Engineering Companies (ACEC) as part of the 2021 Engineering Excellence Awards.

The Coffee Creek Project is part of a Washington State Department of Transportation (WSDOT) endeavor to address the important ecological and economic problem of opening up spawning habitat for stranded salmon as part of a duty based on a treaty to preserve fish routes for 21 tribes in the northwest of the tracks for the tribal harvest. The state is working to remove obstacles at nearly 1,000 water crossings under Washington’s roads.

“This prestigious award recognizes a significant contribution to environmental justice through the restoration of tribal resources and to the engineering profession by providing a model for the future application of design-build to projects emphasizing the restoration of stream systems and fish-friendly habitat in the built environment, ”said Ethan Melone, Pacific Northwest region manager for Parsons. “We are proud to be part of this unique project and honored by this recognition which reflects our commitment to providing unmatched value to our customers. “

For the first time ever as part of a stand-alone fish passage project, WSDOT implemented a design-build approach to a project to remove fish barriers at Coffee Creek on the Olympic Peninsula of Washington. Parsons has developed an Alternative Technical Concept (ATC) as part of the procurement process. This ATC addressed the hydraulic / hydrological and geomorphic complexity of stream systems, providing significant habitat improvement in a smaller construction footprint, while reducing the impact on the traveling public and improving the geometry of interchanges.

The completed project is already an ecological success, as spawning salmon were sighted in the new Coffee Creek channel upstream and downstream of the crossing just weeks after it opened.

The ACEC Engineering Excellence Awards are an annual competition that recognizes engineering companies for projects that exemplify an exceptional level of innovation, complexity, achievement and value.
