Lyon Creek Flood Mitigation and Fish Passage

Facet provided project management, design, and construction oversight of 1,450 LF of this award-winning stream and culvert improvements project in the Lake Forest Park Town Center. Completion of the project eliminated frequent flooding in Lake Forest Park that had inundated the City’s only fire station, largest commercial center, over 20 homes, and State Route 522. This $6.94 million project also restored the lower reach of Lyon Creek, which is an urban salmon-bearing stream, with the removal of numerous fish barriers, installation of large woody debris, excavation of in-stream refuge pools, and reestablishment of two wetlands. Facet guided the project through a rigorous permitting schedule including submittals to six different regulatory agencies.
