Jones Creek Debris Flow Risk Reduction

CIPwebsiteJones

Summary

The Whatcom County Flood Control Zone District (FCZD) is designing two earthen and rock berms to reduce the risk of Jones Creek debris flow hazards to the Community of Acme, WA. Prior work included debris flow studies in 2004 and 2010, a roadway alternatives analysis in 2017, and several community meetings.

Project design is nearing completion and includes:

  1. An approximately 400-ft long deflection berm located at the apex of the alluvial fan 
  2. An approximately 2,500-ft long setback berm that will cross Turkington Rd 
  3. Realignment of a portion Turkington Rd and Galbraith Rd (private) to accommodate the berm(s)
  4. Relocation of associated utilities

Project Benefits

  • Improve public safety
  • Reduce risk to public infrastructure
  • Protect and enhance creek and habitat forming processes 

Jones Creek originates on Stewart Mountain and flows across its alluvial fan through the town of Acme before entering the South Fork Nooksack River. The town has been subject to debris flows from Jones Creek throughout its history. Several debris flow studies characterize the hazards and identify protection opportunities. A large event would impact numerous residential properties and farmland, County roads, and the Acme Elementary School. The goal of this project is to reduce risk to life and property associated with Jones Creek debris flows.
