physical / Ravenna Creek Reroute
Ravenna Creek Project
King County's Wastewater Treatment Division will be installing a new pipeline in some sidewalks between Northeast 54th Street and Northeast 45th Street in Seattle. This project will take clean water from Ravenna Creek that flows into a sewer line and move it into a new pipe to 45th Northeast and into Lake Washington.
The creek flows are now treated unnecessarily at King County's West Point Treatment Plant in northwest Seattle. Moving them through the new pipe to Lake Washington will reduce costs and make room within the sewer system.
Ravenna Creek--History and other projects
Ravenna Creek used to flow from Green Lake to Lake Washington through the current location of Cowen and Ravenna parks. Because of development, the creek was diverted into a sewer pipe and now exists aboveground only within Ravenna Park, where it is fed by springs and runoff.
Since 1990, plans to restore the creek to the surface (called "daylighting") within the park boundaries have been in development. King County will transfer the creek into a new pipeline, and the City of Seattle will daylight a portion of the creek within Ravenna Park.
