Risk based planning

Planners have a delegated responsibility to plan for the future of our cities, to ensure that the safety and security of present and future communities are not compromised by urban growth, development and renewal. As such, land-use planning is often described as an opportune tool available for reducing or even eliminating risks related to natural hazards.

Many land use planning policies and decisions are based around ‘a number’, such as the 1/100 year event, and/or an undefined level of risk, such as an ‘acceptable level of risk’. This has led to many developments being approved which have increased the risks (or potential risks) to people and property. To assist planners in defining levels of risk and to promote a risk-based approach to land use planning for natural hazards, a five-step risk-based approach to natural hazards planning has been developed with an associated engagement strategy.

This toolkit outlines the approach, and will be of interest to decision makers, planners, and others with an interest in risk-based planning.
