Skin Gulch Floodplain Restoration Design and Implementation (CO) 2014-2016

 

OVERVIEW: A tributary to the Cache La Poudre River (Colorado), the 6.8 acre Skin Gulch floodplain restoration site was heavily impacted by post-fire flooding and debris flows, resulting in severe channel degradation and floodplain aggradation. The site was subsequently cleared of debris and fill soil removed, leaving a denuded, vulnerable floodplain and impaired channel. We revegetated over 1.1 miles of Skin Gulch using container stock, seeding, wood straw, erosion matting, willow/cottonwood cuttings, soil amendments, fascines, and soil/vegetation covered rip-rap. Structures included step pools, grade control, toe walls, and gulley stability (zuni bowls and grade control weirs). Vegetation and structures controlled erosion and facilitated recovery of the wetland and riparian areas.

 

ALOTERRA’S design team provided project feasibility assessment, concept and final designs, team development and project management. We executed construction for creek realignment and instream structures as well as post-construction monitoring. We also implemented erosion control, weed management, bioengineering, and wetland and riparian restoration.
