Strategies for Classifying Risk & Priority Areas Using ArcGIS: A Qualitative Assessment of the UBC Point Grey Cliffs

GEOB 308 - Term Project: GIS Analysis of erosional hazards on the Point Grey cliffs at UBC using data collected from site surveys and relevant scientific literature.

This study undertook a qualitative assessment of slope stability of the Point Grey Cliffs through an evaluation of literature and field site visits. Data was analyzed to produce a map of relative instability risk for our selected sites. Vegetation, D50 and slope angle appeared to be significant components of instability, and areas with low vegetation, high slope angle and certain D50 values were found to underlie high-risk slopes. The figures we created holds important implications for future development considerations in terms of stormwater routing and further land development.
