            * Risk of smoke impact has not been assessed. Smoke can travel long distances and exhibit a variety of densities and
            composition. It is therefore not readily practicable to determine the separation distances needed to attain the various risk
            classes. Furthermore, individuals will react differently to smoke impacts whereas individuals will generally exhibit similar
            reactions to direct flame and radiant heat.

            All identified ‘Intolerable risk’ assigned to the new buildings is expected to be reduced to at least a
            ‘Tolerable risk’ where buildings are constructed in accordance with the National Construction Code
            2019 (NCC 2019) AS3959:2018 Construction of Buildings in Bushfire Prone Areas requirements.

            5.3     Qualitative Risk Discussion
            Expansive units of flammable vegetation are located in proximity to the site which have the potential
            of facilitating either a direct bushfire front onto the site and/or facilitating advance ember attack and
            radiant heat impact to the site. A discussion of the directional risk acting on the buildings associated
            with Lots 8, 9 and 12 follows.

            5.3.1 North
            The VHC 8.1 tall open forest to the north of the proposed building envelopes exposes them to varying
            risk of direct flame, radiant heat, ember and spotting impact in the absence of additional mitigation
            measures being employed. The degree of separation offered to the VHC 8.1 hazard is the primary
            driver of the assigned level of risk and was determined with consideration to the Flamesol modelling
            output presented in Section 4.
