The previous flow splitter directed stormwater flows from 156th Ave NE. Approximately 15% of the flows drained to Tosh Creek with the remainder flowing down the NE 51st Street trunk, which discharges into the wetlands near West Lake Sammamish Parkway. The project made minor modifications to the flow splitter to optimize its control of flows, reducing high flows to Tosh Creek while maintaining the base flows necessary for stream health.
