The 2.55-acre Project of three riparian meadows with incised stream channels and actively evolving head cuts that rapidly drain the meadow floodplains, resulting in reduced residence time of water, reduced riparian wet-meadow habitat for amphibians or native fish, reduced stream complexity, increased erosion, and rapid drying following spring snowmelt have been selected for restoration.
All in-stream restoration activities will follow process-based design criteria and do not require engineered designs due to the planned use of on-site, natural materials and stream energy while minimizing overall disturbance. Instream project designs will include low-tech biogenic structures such as post-assisted log structures (PALS) and beaver dam analogs (BDAs), which are ephemeral structures that are used to treat channel head cut features by allowing sediment to aggrade in the channel and halt stream incision. It is anticipated that by adding structural complexity to incised channels upstream sediments will be deposited and aggrade the channels, especially within the wildfire footprints, leading to more floodplain connectivity and subsequent inundation. Restoration also includes removing meadow-encroaching conifer trees which are not adapted to desired wet-meadow conditions
