                 6.1.1    BUSHFIRE BEHAVIOUR

                 Modelling results based on the AEP 5% FFDI indicated that:

                    ● the subject land did not contain hazardous vegetation and did not contain areas of
                         potential fireline intensity,
                    ● although parts of proposed lot 1 is within the potential impact buffer, the proposed lots
                         are separated from areas of potential fireline intensity located to the northwest by Hoy
                         Rd.

                 Figure 7 shows the location of bushfire prone areas.

                 Modelled bushfire prone areas differed from the extent and classification of bushfire prone
                 areas indicated by both the SPP State-wide map of bushfire prone areas and the Noosa Plan
                 Bushfire Hazard Overlay. The differences were attributable to the following factors:

                    ●    vegetation hazard class mapping based on pre-2017 vegetation cover and regional
                         ecosystem mapping,
                    ●    mapping errors and anomalies e.g., incorrect classification of Vegetation Hazard
                         Classes
                    ●    the effect of recent development on the configuration of vegetation within the
                         landscape.
                    ●    consequential ‘patch and corridor filtering’ based on the observed configuration of
                         VHCs.

                 The area of potential fireline intensity currently indicated on the Noosa Plan Bushfire Hazard
                 Overlay and the SPP map of bushfire prone areas was found to be an area of native to
                 modified pasture with scattered to isolated, cultivated trees (Hoop Pine). The latter is a non-
                 bushfire prone vegetation hazard class and does not contribute to areas of potential fireline
                 intensity.

                 In addition, the proposed revegetation of the environmental covenant area does not
                 contribute to bushfire hazards. Retention of existing native vegetation, removal of weeds and
                 enhancement planting of trees as part of the Rehabilitation Concept Plan does not contribute
                 to creation of new hazards as the planting has been designed to incorporate trees only, such
                 that surface and near-surface fuel loads remain discontinuous and are less than 8 tonnes per
                 hectare in aggregate.
