Catiline Creek Debris Flow Mitigation Service Project

Electoral Area C

Project overview

The Catiline Creek Debris Flow Mitigation Project is a major infrastructure initiative to design, construct, and establish operation and maintenance of a debris flow mitigation structure for the Catiline Creek at Lillooet Lake Estates. The objective of the project is to reduce the risk to the community and potential for loss of life by increasing capacity of the existing channel to manage future debris flows up to 100,000 cubic metres through the community, under a new forest service road bridge, and into Lillooet Lake. The SLRD is working closely with the Ministry of Forests to coordinate the Ministry’s replacement of the In-SHUCK-ch bridge over Catiline Creek in conjunction with the project. To learn more about the debris flow hazard, assessments and the SLRD Board’s "Do Not Occupy" Recommendation, visit the SLRD local hazard webpage for the Catiline Creek Debris Flow.
