Abstract/Description or Keywords | For residential development to proceed on ground potentially exposed to a landslide hazard in British Columbia approving authorities require a letter from a professional engineer or geoscientist stating that the site is safe for the intended use. Safe, however, is nowhere defined and there is no consistent guidance on this matter. APEGBC (2008) discourages its members from making such statements in their reports unless “safe” is explicitly defined. This paper reviews the development and application of the landslide risk tolerance criteria used in North Vancouver and compares the criteria with risks faced by Canadians in everyday life. Landslide scenarios most amenable to a quantitative riskbased management approach are distinguished from scenarios where “safe” sites might be more appropriately defined by a factor of safety or hazard probability. |
