Abstract: This report presents an approach for incorporating risk-based land use planning into a New Zealand district plan chapter. The risk-based approach has been developed as part of a PhD thesis by Wendy Saunders (Saunders, 2012) and has been further refined under an Envirolink Tools project. The risk-based approach allows for the considered of both the consequences and the likelihood of a natural hazard event as opposed to the traditional planning approach of considering only the likelihood of an event. The district plan chapter has been prepared for “Urban Valley’, a fictitious urbanised city in New Zealand. The district plan chapter is an example of how an integrated risk-based approach can be used when making land use planning decisions. The objectives and policies of the district plan chapter identify the risk outcomes for natural hazards in Urban Valley. The corresponding rules have been developed based on the risk to existing and future development, while ensuring that the risk outcomes sought under the objectives and policies are achieved. It is assumed these rules are associated with hazards zones, shown on planning maps. These hazards zones show the extent of an area affected by a natural hazard, based on a likelihood determined by the council. The district plan chapter also sets risk-based anticipated environmental outcomes, methods of implementation and monitoring approaches and outcomes. This example is not intended to be a ’model chapter’ that can be used in all district plans by all local authorities. Rather, it is seeking to show that a comprehensive risk-based approach to planning for natural hazards can be undertaken under the existing legislative framework in New Zealand. (auth)
