Landslides in the Urban Environment
Wednesday, November 6th, 2013
Mr. Hawk has experience with a variety of geotechnical projects in the Southern California area. As a private geotechnical consultant, he has participated in or managed preliminary geotechnical investigations and in-construction review for hillside, residential, and commercial development in Los Angeles, Orange, and San Diego Counties, as well as highway bridges in Imperial County. Mr. Hawk worked for the City of San Diego as a Senior Engineering Geologist and Deputy City Engineer for over 20 years supervising all review of geotechnical reports submitted for discretionary review, land development, and grading. Mr. Hawk officially retired from the City in 2009, but continues to work for the City as an as-needed provisional employee in addition to private consulting in coastal studies and stabilization. He is a licensed geologist, engineering geologist, hydrogeologist, and civil and geotechnical engineer.
The presentation will discuss the various types of landslides that occur in San Diego using the USGS classification and local examples, with a discussion of how they occur, what is done currently to address the problem, and the role of the geologist in their detection, evaluation, and mitigation. In 2007, a major landslide destroyed two roads, 5 homes, and damaged 6 others in a residential subdivision on Mount Soledad in La Jolla, a community in San Diego. Mr. Hawk served as the supervising geologist during the discovery, disaster response, reconstruction of the roadways, as well as geotechnical expert and defendant on behalf of the City during the subsequent litigation. Wednesday’s talk will include the case study of the Soledad landslide from detection to mitigation, and his role as the geologist in the process.
