The inevitable public unease in the wake of large infrastructure failure prompts questions regarding how to properly define and manage the risks of various engineered activities to socially acceptable levels. A changing climate may add additional vulnerability to infrastructure and thus should be considered in risk management strategies. Current implementations of risk management processes differ across agencies, but often rely on a concept of Tolerable Risk. The Tolerable Risk is a numerical value for the boundary in a continuum of management alternatives below which risk is tolerated to secure societal benefits, though engineering interventions may be still be necessary and proper to achieve higher degrees of protection.
