AEG Spring Meeting April 23rd
We are excited to be welcoming Jim Lemmon, Geologist for Arizona Department of Transportation. We will be meeting at Terracon’s offices (address below).
“The Scope of Geohazards in Arizona Impacting Highways”
Arizona has three main physiographic provinces including: the Colorado Plateau with predominately flat sedimentary rock layers; the Transition Zone with the northwest to southeast trending mountain ranges and narrow valleys; and in southern Arizona the northwest to southeast trending Basin and Range Province. These basins are often many miles wide and filled with several thousand feet of alluvial materials typically containing hundreds of feet of deep unconfined aquifers, remnants of a much wetter period in Arizona’s geologic history. These three large geographic areas have common and sometimes unique geologic hazards. Examples of these hazards include: landslides, post wildfire issues, debris flows, rock falls, sinkholes, earth subsidence impacts, earth cracks and giant desiccation cracks. The remedies employed by transportation geotechnical practitioners are varied depending on geologic conditions, budget and the risk to the traveling public.
