Community Hazards - Dawson - 30m


Data Identification
Abstract: Landscape hazard maps were completed as part of a community hazards mapping program coordinated by the Northern Climate ExChange (Yukon Research Centre, Yukon College). Potential landscape hazards were assessed under changing future conditions by incorporating a variety of data sets, including surficial geology, topography (slope and aspect), permafrost distribution, site-specific permafrost data (e.g. ground penetrating radar, electrical resistivity tomography and borehole data), analyses of past hydrological and climatological trends, and future climate projections. The landscape hazard map identifies existing and potential geological hazards such as landslides, permafrost stability and flooding. The hazard map is presented in stoplight colours to provide an intuitive tool for community decision makers aiming to incorporate an adaptation planning framework into existing land use management practices. Detailed descriptions of data inputs and hazard analysis methodology are presented in an accompanying report (available for download from http://ygsftp.gov.yk.ca/publications/openfile/2014/OF2014-12/Dawson_report.pdf). An accompanying surficial geological map also describes detailed landscape characteristics such as surface landscape features, sediment texture, genetic material, surface expression and geomorphological processes (available for download from http://data.geology.gov.yk.ca/Reference/DownloadProduct/49699).
Purpose: These data identify potential landscape hazards such as permafrost, landslides and flooding for the greater Dawson area. Hazards were assessed by evaluating surficial geology maps, permafrost probability models, detailed permafrost investigations, analyses of past hydrological and climatological trends, and future climate projections. The hazard data are ranked and symbolized using stoplight colours. Hazard maps serve as an adaptation planning tool that can support responsible, forward-looking decisions related to climate change impacts on communities. Hazard maps can be used by communities, First Nations, engineers, planners, consultants, and all levels of governmental and non-governmental decision-makers.

Constraints: These data are intended for community scale (1:10,000-1:25,000) planning and educational purposes only. They do not replace the need for detailed site specific engineering studies prior to construction or development projects. The accompanying report should be consulted for appropriate interpretation of this data.These data (the “Information”) convey general observations only. The Information is based on an interpretation and extrapolation of discrete data points and is not necessarily indicative of actual conditions at any location. The Information cannot be used or relied upon for design or construction at any location without first conducting site-specific geotechnical investigations by a qualified geotechnical engineer to determine the actual conditions at a specific location (“Site-Specific Investigations”). The Information should only be used or relied upon as a guide to compare locations under consideration for such Site-Specific Investigations. Use of or reliance upon the Information for any other purpose is solely at the user’s own risk. Yukon College and the individual authors and contributors to the Information accept no liability for any loss or damage arising from the use of the Information.
