Slope Instability Studies - Ottawa Area: Slope Stability Classification

Coordinate system: 2030

Abstract:

The Slope Instability Studies - Ottawa Area: Slope Stability Classification data set consists of the following six classes based on computed factors of safety:

  • 0.8 unsuitable for construction or will require extreme remedial measures in order to safely use the site
  • 0.8 - 1.2 will require extensive remedial measures
  • 1.2 - 1.5 detailed geotechnical investigation necessary, with concomitant remedial works
  • 1.5 - 2.0 routine geotechnical investigation necessary
  • 2.0 - 2.5 routine inspection necessary to determine the need and extent of geotechnical investigation
  • > 2.5 should be inspected but no remedial action likely to be required
  • Please note that this data set contains overlapping values and that this is only one representation of the data.

    This data set is part of the The Slope Instability Studies - Ottawa Area Data Package. The Data Package is composed of digital reports and a map series with accompanying GIS data. These studies were conducted in 1976 and 1983 and the accompanying maps and GIS data are based upon this information. Please use caution when interpreting data and results. The Data Package can be obtained by searching for the Slope Instability Studies - Ottawa Area Data Package on the GeoPortal.

    Digital reports are available for download from the additional documentation section.
