SLRD Regional Geohazard Risk Assessment - 2023 Update
From 2018 to 2020, Squamish Lillooet Regional District (SLRD, the District) undertook a regional district-wide geohazard risk assessment that assessed flood, steep creek (debris flood and debris flow), and non-eruptive volcanic hazards (lahars). From 2021 to 2023, the SLRD engaged BGC Engineering Inc. to update the original study to address two key recommendations: understanding how wildfires could affect steep creek risk compared to existing conditions (i.e., a baseline risk assessment scenario) and resolving under-reported hazard exposure on First Nations reserves caused by gaps in asset data. This assessment incorporates revised methods and expands on the initial steep creek hazard inventory. This assessment supersedes both the report and the results of the previous study.
The goal of this geohazard risk assessment is to support decisions that prevent or reduce injury or loss of life, environmental damage, and economic loss due to geohazard events. Completion of this study is a step towards this goal. The study encompasses four electoral areas, eleven First Nations, and four municipal governments.
