Buildings and developments in any geographic location can be subject to a wide variety of natural phenomena such as windstorms, floods, earthquakes, and other hazards. While the occurrence of some of these events cannot be precisely predicted, their impacts are well understood and can be managed effectively through a comprehensive program of hazard mitigation planning. Mitigation refers to measures that can reduce or eliminate the vulnerability of the built environment to hazards, whether natural or generated by human activity. The fundamental goal of mitigation is to minimise loss of life, property, and the function of services/systems due to disasters. Designing to resist any hazard(s) should always begin with comprehensive hazard/threat and risk assessments. This process includes identification of the hazards present in the location and an assessment of their potential impacts and effects on the built environment based on existing or anticipated vulnerabilities and potential losses.
Regardless of who is conducting the risk assessment, the fundamental process of identifying what can happen at a given location, how it can affect the built environment, and what the potential losses could be, remains essentially the same from one scenario to the next. Only after the overall risk is fully understood should mitigation measures be identified, prioritised, and implemented.
Basic principles underlying this process include:
