Stantec Assisting City of Kirkland to Improve Fish Passage, Reduce Flooding in Cedar Creek

Replacement of 100th Avenue NE culvert will lead to better stream health

08/28/2019 KIRKLAND, WA TSX, NYSE:STN

Stantec—a global engineering, architecture, and consulting firm—is helping the City of Kirkland improve fish passage and reduce flooding in Cedar Creek by replacing an aging culvert at 100th Avenue Northeast.

The design team recently submitted a 30-percent design to the U.S. Army Corps of Engineers for permitting on the $1 million project.

“By working with the City of Kirkland we have an opportunity to restore a key stretch of Cedar Creek,” said Jim McPherson, Stantec project manager, based in Bellevue. “The project will bring back a more natural channel and provide a longer path for flow than currently exists. That will allow natural vegetation to come back. Supporting aquatic habitat is a priority within the community and within the state. This project supports that goal, providing the best return on investment to the City of Kirkland.”

Stantec’s role is to help the City design and build the new culvert in a way that minimizes the work’s effect on traffic flow. The City of Kirkland is planning to begin construction next summer on the culvert.

The original Cedar Creek 36-inch concrete box culvert is structurally degraded and the size and orientation of the culvert blocks fish passage. The downstream channel is eroded from high flow events and high-water velocity due to the culvert conditions. Upstream, the storm-detention structure is outdated and does not provide adequate flow control, prevents sediment transport, and limits the natural function of the upstream habitat. This project will resolve these issues, opening habitat for salmonids and other fish species and will reduce the risk of flooding in the community.

“This project is important for the health of our streams and all of the species that depend on them,” said Kirkland Project Engineer Laura Drake. “It’s also a vital component of the 100th Avenue Northeast Corridor, one of Kirkland’s three north-to-south corridors. We are happy to have Stantec to guide us through the process of improving it.”

Stantec is providing project management, civil design, biological design, structural design; and environmental permitting, mitigation and restoration design. Stantec’s local team of engineering and environmental experts includes more than 350 professionals. The firm has completed more than 85 fish-passage projects in Washington and Oregon.

The project is expected to be completed in October 2020.
