Wonderland Creek Greenways Improvement Project: Foothills Pkwy. to Winding Trail

Check out the video presented at the 2019 Colorado Association of Stormwater and Floodplain Manager's annual conference

 

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 channel improvements for this segment of the creek to contain the flows associated with the 1% annual chance flood (aka 100-year floodplain). By creating these improvements, the city will be reducing the flood risk to numerous structures and dwelling units that are currently located within the 1% annual chance special flood hazard area 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. 1,884 new trees and shrubs were replanted. 

Current Project Status

The Wonderland Project was completed on April 18, 2019! Contractors may be seen throughout the project area during the two-year warranty period to address any issues covered by the warranty. Thank you to everyone in the community for your patience and understanding throughout this project. 

Existing Conditions

The existing 1% annual chance special flood hazard area 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.
