Apple Valley Stream Restoration

Apple Valley is small community located just outside of the Town of Lyons, along the North St. Vrain Creek. During the 2013 Colorado Flood, the floodplain resulted in a loss of life and property. The design aimed to achieve flood recovery, improve the connectivity and habitat of the floodplain through stream restoration, and increase long-term flood resilience for future flood events.

Scott Shipley, the Co-Founder of Birch Ecology and the President of S2O Deisgn, along with the S2O Design team, completed all preliminary planning through the 30% design drawings for a 2.7-mile stretch of the Apple Valley Stream Restoration Project.  The design included channel realignments, braided overflow channels and expanded floodplain terraces.

Upon completion of the 30% design, S2O was awarded the Apple Valley South Design-Build contract for the .9 mile lower portion of the Apple Valley Stream Restoration Project. The design included the construction of habitat boulders, rootwads, hardened riffles and pools, controlled overflow channels, and vegetated floodplain terraces. The project was sustainably planted and seeded with native, riparian vegetation.
