Hazardous Dams, Flood Risk, and Dimensions of Vulnerability in California by Britta McOmber Master of Urban and Regional Planning University of California, Los Angeles, 2018 Professor Susanna B. Hecht, Chair In the state of California, dams are aging, underfinanced, and in many cases ill-maintained. The Oroville Dam Spillway Failure in February 2017 demonstrates that even dams with satisfactory condition ratings can be at risk of failing from a combination of climatic, political, economic, and structural factors. It is therefore necessary to look beyond the condition assessment of a dam and instead consider the hazard potential status. California has 833 High Hazard Potential (HHP) dams – which the U.S. Army Corps of Engineers defines as dams that would cause significant loss of life, property destruction, or environmental damage in the case of failure or misoperation (2016). Expanding on previous literature on the sociodemographic determinants of flood-risk in cases of sea-level rise, climate change, high precipitation, and storm events, this project analyzes variables of social vulnerability within HHP dam inundation boundaries.
