Sky Valley Community Floodplain Solutions (CFS) Project

Project Description


The Skykomish River runs through the heart of the North Cascades along rich farm land before it joins the Snohomish River, flowing west to Puget Sound. The project area is focused on the upper reaches of the Skykomish River in the Sky Valley region near the City of Sultan. The area is a busy agricultural center and popular destination for fishing and outdoor recreation. It also attracts new homeowners seeking affordable housing and a rural lifestyle.

The Skykomish River has a long history of flooding and river migration. Flooding and erosion regularly impact farms, businesses and residential properties and force the closure of local roads. This ongoing flood risk is complicated by the continued loss of critical salmon habitat, essential for the recovery of Chinook and the Southern Resident Orca. 

Community Floodplain Solutions (CFS) – Sky Valley seeks ways to allow the Skykomish River and its tributaries room to migrate while preserving land for multiple uses.

The CFS - Sky Valley project includes plans to:
  • Reduce flood-related risk to people and public infrastructure 
  • Remove three fish passage barriers and culverts, which will improve access to 2.6 miles of stream habitat
  • Restore up to 30 acres of habitat along the Skykomish river banks
  • Protect up to 200 acres of floodplain land for future restoration and long-term agriculture uses
  • Model, assess, and map river conditions to inform future projects
  • Complete design for an integrated floodway project and three agriculture resilience projects
  • Educate and learn from residents about living in a dynamic floodplain to better understand future river migration risks

Location


The Community Floodplain Solutions–Sky Valley project covers approximately 2550 acres within the FEMA 100-year Floodplain Boundary of the Skykomish River near the Sultan city limits.
