Wonderland Creek Greenways Improvement Project: Foothills Pkwy. to Winding Trail
*Please click the photo above to take a virtual tour of the Wonderland Creek construction project.
The Wonderland Creek project construction began in January 2016. The project extends from Foothills Parkway in the south to Winding Trail Drive in the north. The purpose of this approximately $30M project (cost includes design and construction) is to provide 100-year channel improvements for the aforementioned segment of the creek. By creating these improvements, the city will be reducing the flood risk to numerous structures and dwelling units that are currently located within the 100-year floodplain. In addition, we will be building three new underpasses (1. at the BNSF Railroad 2. Kalmia Ave. 3. 28th St.) to provide safe passage for pedestrians and cyclists as we extend the multi-use path system from Foothills Parkway to 30th St. In order to create these new features, approximately 450 trees have been removed along the project reach. Once the construction is complete, 1,884 new trees and shrubs will be replanted.
Current Project Status
The Wonderland Project is now over 98 percent complete. The following major componenents have been constructed:
- Almost a mile of new channel and multi-use path;
- A large pipe system under Iris Avenue to connect the creek;
- Relocation of a large segment of irrigation ditch to eliminate flooding of the ditch in the King's Ridge/Noble Park neighborhood;
- A new railroad bridge near Foothills Parkway;
- An underpass at 28th Street; and
- An underpass at Kalmia Avenue
The remaining major construction efforts include:
- Completing channel work, multi-use path and wall systems along Winding Trail;
- Final top-surface paving of 28th St.;
- Installation of trellis along walls and hand rail throughout the project area.
We anticipate completing all major work on 28th Street intersection and along Winding Trail during the spring 2018. The multi-use path system east of 28th Street is anticipated to be operational in mid 2018. Final project landscaping and minor repairs will likely extend into summer/fall 2018.
Contractors have been granted the following exception(s) to work outside of regular construction hours (M-F; 7 a.m. - 5 p.m.):
- Thursday, 21 June 6:30 a.m. - 8 p.m. work will include milling of asphalt and final asphalt paving at: Winding Trail, 28th St., Iris Ave and some private property locations.
- Saturday work has been granted for irrigation and landscaping through the end of the project.
The existing 100-year floodplain along Wonderland Creek between Foothills Parkway and Winding Trail extends far beyond the creek banks and includes numerous structures. A 2009 flood mitigation master plan recommends flood improvements for this segment of Wonderland Creek.
A multi-use path connection is called for in the Greenways Master Plan and Transportation Master Plan from Foothills Parkway to 30th Street. The plans also call for a pedestrian and bicycle underpass at 28th Street. These two combined projects along Wonderland Creek will provide flood mitigation and trail improvements, fulfilling master plan goals.
