            5     SPP BUSHFIRE RISK ASSESSMENT

            5.1       General
            A bushfire risk assessment for the site has been prepared generally in accordance with State
            Planning Policy – State Interest Guideline – Natural Hazards, Risk and Resilience (DILGP, 2016)
            and AS/NZS ISO 31000:2018 – Risk Management Methodology. The bushfire risk assessment
            details the likelihood that the proposed new buildings will be exposed to bushfire smoke, ember,
            radiant heat and/or flame attack considering the proximity to bushfire prone vegetation and likely
            bushfire behaviour.
            According to AS/NZS ISO 31000:2018, a ‘hazard’ is defined as a source of potential harm or a
            situation with a potential to cause loss, whereas a ‘risk’ is the chance of something happening that
            will have an impact on objectives measured in terms of consequences and likelihood. The State
            Planning Policy – State Interest Guideline – Natural Hazards, Risk and Resilience (DILGP, April
            2016) refers to ‘acceptable risk’, ‘tolerable risk’, and ‘intolerable risk’ which are defined below.
                  •    Acceptable risk
                           o    A risk that, following an understanding of the likelihood and consequences, is
                                sufficiently low to require no new treatments or actions to reduce risk further.
                                Individuals and society can live with this risk without feeling the necessity to reduce
                                the risks any further.
                  •    Tolerable risk
                           o    A risk that, following an understanding of the likelihood and consequences, is low
                                enough to allow the exposure to continue, and at the same time high enough to
                                require new treatments or actions to reduce risk. Society can live with this risk but
                                believe that as much as is reasonably practical should be done to reduce the risks
                                further.
                  •    Intolerable risk
                           o    A risk that, following an understanding of the likelihood and consequences, is so high
                                that it requires actions to avoid or reduce the risk. Individuals and society will not
                                accept this risk and measures are to be put in place to reduce risks to at least a
                                tolerable level.

            5.2       Risk Assessment
            The risk attributed to the hazardous vegetation within the assessment area and immediately beyond,
            in the absence of additional mitigation measures being implemented, is detailed in Table 2 for Lot
            12, Table 3 for Lot 8 and Table 4 for Lot 9.
