Parkway Drive Landslide, Evaluation and Remediation, and Risks with the Expanding Urban Interface Part 1
« All Publications

NOTE: This topic / abstract is intended to be presented in two separate presentations; one focusing on the landslide identification and causation, and the other on mitigation design and construction. The first presentation (identification and causation) would be given by the Author, and the other (mitigation design and construction) given by the Co-author.

In 2014 the Parkway Drive Landslide occurred in dramatic fashion destroying several structures in a hillside development of North Salt Lake, Utah. Historical land use included decades of aggregate mining and in the more recent years, development progressively moved into the foothills where the area was sculpted to accommodate the urban interface.  The landside provides several excellent examples of geological conditions when combined with decades of anthropogenic influences, results in the initiation of the mass movement and ultimately the loss of property.  This presentation will provide an overview and details of the historical and local geological setting, a review of causal factors and associated analyses and instrumentation, development of mitigation solutions and related analyses, and implementation and construction of the landslide stabilization.
