This project is part of the City of Kent's Green River Levee Improvement Program. The program includes an engineering evaluation of the levees along the east side of the Green River and rebuilding or improving levees as needed. The Boeing Levee is located along the east side of the Green River between S. 200th Street and S. 212th Street. It connects to other levee segments included in the Green River Levee Improvement Program. Together, these levees reduce flood risk in approximately two-thirds of the Kent Valley.
Construction at the Boeing Levee was completed in the City's Three Friends Fishing Hole Park in 2013. The City's contractor built a secondary levee through the parking lot and a flood wall was installed behind the park to reduce flood risk.
Construction will included:
- Approximately 220 linear feet of new earthen levee.
- Approximately 740 linear feet of I-walls (reinforced concrete wall built on top of sheet piles).
- A decorative artwork design was applied to the concrete wall.
- Raising and grading of the parking lot and bridge enbankment to maintain access aesthetics.
- Restoration of the entire park site upon project completion.
Separate from the setback levee and floodwall project, the City has formed a partnership with the U.S. Army Corps of Engineers to design an Ecosystem Restoration Project on the east bank of the river starting south of the Three Friends Fishing Hole Park and extending to S. 212th Street. The project will remove excess material from the river bank and will plant native vegetation to enhance habitat along the river banks from S. 200th Street to S. 212th Street. The project will also improve the connection to the Green River, consistent with the city's vision of the river as an important resource to the City of Kent.
