Erosion hazard setbacks are becoming a popular policy tool to protect infrastructure and property from potential stream erosion issues. In Texas, the premier example is a policy used by the City of Austin since 2004. Different approaches to preventing and coping with stream erosion focus on different variables, including stream discharge, slope, and bed and bank material. The variability in accepted setback methodologies highlights the growing need to better understand the complexities of stream systems. Additionally, investigation of the purpose for and the reasoning behind establishing erosion hazard zones would inform stakeholders as they attempt to choose the best course of action to protect their communities from stream erosion hazards. This presentation examines several current procedures for establishing erosion hazard setbacks and explores how additional setback criteria may be developed; collaboration on new setback methodologies may provide an important educational opportunity for researchers and practitioners alike.
