Site work for a civil project in Mill Creek, Washington. Conceptual plans call for site work for a bridge / tunnel; and water / sewer project.

This project is intended to address both the fish passage issues and flooding that occurs along Old Seattle Hill Road where it crosses Nickle Creek. During large rain events, water upstream (east) of the road backs up and overtops the road, leading to at least one lane being closed. Staff has performed additional investigations and found that the culvert in question is also labeled as a partial fish passage barrier by the Washington State Department of Fish and Wildlife (WDFW). Therefore, this project will remove the culvert that serves as barrier and install it in compliance with WDFW’s current fish passage design guidance. This will allow not only fish to traverse the area, but will also remove the barrier that causes flooding, improving safety along the road. There are many additional funding sources for fish passage projects, so grant funding is anticipated. This project is a companion to the Old Seattle Hill Road Reconstruction project (ST00007). As of May 08, 2025 ,This project is included in the city's 2025-2030 Capital Improvement Program (CIP) *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
