Disaster Risk Assessment
The risk assessments are for the Redland City mainland coastal, hinterland and island communities (refer to map for more information). This plan focuses on the likelihood and affects of disasters occurring within the Redland City and recognises that Redland City is made up of a “community of communities” that face their own unique challenges during disaster events. Council’s risk management processes are based on Australian Standard AS/NZS ISO 31000:2009.
Risk assessment is a process of evaluating the source and possible consequence of the risk, and the likelihood that those consequences will occur. This is achieved through the Risk Rating Matrix below, where the consequence of the risk is mapped against the likelihood that the risk will occur, which provides a risk rating level – low, medium, high or extreme. An explanation of the criteria for risk likelihood descriptors and risk consequence descriptors appears in the following tables.
