Otak Helps the Fish Pass Through in Zackuse Creek
November, 2018
On a recent Saturday, nearly 20 Otak employees and their friends joined in planting the riparian buffer of the Otak-designed Zackuse Creek Fish Passage and Stream Restoration Project.
The City of Sammamish partnered with King County to upgrade three undersized culvert pipes to fish-passable box culverts in the first 400 feet of stream above the confluence with Lake Sammamish. Otak designed the third fish-passable culvert, under a major arterial, and realigned and restored over 400 feet of the creek upstream of the culvert and within private property.
Improvements included creating a more sinuous, stable channel with step pools, boulder bands, and woody debris appropriate for Kokanee spawning. Many key stakeholders were involved from the early stages of planning through design and permitting, including assisting during public outreach. This level of public involvement was greatly reflected in the diverse group of 100 people who came to help replant the area near Zackuse Creek, including the Snoqualmie Tribe (who organized the revegetation work party), families from the neighborhood, City staff, and other community members.
In addition to design, Otak also provided construction support on the project. It was a special opportunity for many on the design team, to put the final touches on a project they had been creating and visualizing through a computer over the previous two years! And such a treat to do so on a sunny day with friends and coworkers! “It felt like Earth Day,” said Kaela Mansfield, water resources engineer. “The Snoqualmie Tribe did a great job of advertising the event.”
Congratulations to Otak’s team: Greg Laird, project manager; Ryan Hawkins, construction management/inspection; Kaela Mansfield and Mike Rafferty, water resources; Eva Ho, Touta Phengsavath, and Dave Cole, civil and utility support; Bob Doherty, culvert/structures; Kevin O’Brien, permitting efforts; Ben Schneider and Lindsay Martin, planting restoration design; and Jeff Gray and Kevin O’Brien, permitting support.
