Construction

Background

Construction of a debris flow mitigation structure along Catiline Creek has been a priority for the community of Lillooet Lake Estates for several years, subsequent to major debris flow events occurring, most recently in 2010 and 2013. The SLRD has worked with the community for a number of years on items related to the debris flow hazard at Catiline Creek.

In September 2022 the property owners and the site owners / shareholders of Lillooet Lake Estates Ltd. petitioned the SLRD to establish a service and borrow up to $4 million for debris flow mitigation at Catiline Creek for both full and phased project options. The cost of service establishment and loan repayments are to be requisitioned via parcel tax to Lillooet Lake Estates property owners.

In December 2022 the SLRD Board adopted the Squamish-Lillooet Regional District Catiline Creek Debris Flow Mitigation Service Establishing Bylaw No. 1786-2022 and Squamish-Lillooet Regional District Catiline Creek Debris Flow Mitigation Service Loan Authorization Bylaw No. 1787-2022, and approved inclusion of service and project resources in the 2023-2027 Financial Plan. More information on this process can be found on the service establishment and loan authorization bylaw page.

Community support for the project, and for the service establishment and loan authorization bylaws are critical elements of this project, including supporting applications for both provincial and national grant programs.

First Nations

Catiline Creek, and the community of Lillooet Lake Estates, lies within the unceded traditional territory of the Líl ̓wat Nation. Since the project’s inception, an important priority for the SLRD has been to engage with Líl’wat Nation, through its land use referrals process. The SLRD sincerely appreciates the time and consideration that Líl ̓wat Nation Land Use Referral Committee members are taking to review the project and is grateful for its conditional support. The project team looks forward to continuing to work with the Referral Committee to ensure that all referrals related to the various provincial and federal permits required for the project will be forthcoming for the Committee’s review, and that archaeological and environmental monitoring is conducted throughout the project. The SLRD is also working to keep Samahquam, Skatin Nations, Xa’xtsa-Douglas First Nation, the Lillooet Tribal Council and the St’át’imc Chiefs Council informed as the project moves forward.
