            Bushfire Hazard Assessment & Management Plan v2                                           NCES REF: J001445
            434 Lake Cooroibah Rd Lake Cooroibah, QLD


            The assigned sub unit slopes are referenced on Plan BF02.
            A FFDI of 47 has been adopted for the site consistent with the assignment by QFES.
            The Flamesol output results are attached as Appendix 3 and summarised in Table 1.

            Table 1 demonstrates Sub unit 2; paperbark open forest, represents slightly more severe bushfire
            behaviour (High Potential Bushfire Intensity) than Sub unit 1a and 1b; eucalypt open forest (Medium
            Potential Bushfire Intensity), which effectively exhibit similar bushfire behaviour.
            The Flamesol results are reflected on Plan BF02 which demonstrates the entire site is captured in a
            Low Potential Bushfire Intensity class.

            4.4     Local Hazard Map
            Plan BF03 – Local Hazard Map identifies the Potential Bushfire Intensity classes across the site
            shown on Plan BF02 and includes a 100m wide Potential Impact Buffer.
            The western and centre portions of proposed Lot 7 are captured in a Potential Impact Buffer whilst
            the east of the Lot is captured in a Low hazard area. The proposed Lot 7 building envelope is located
            in the cleared area in the north-west corner of the lot. On this basis, the building area is located in
            the outer limits of the Potential Impact Buffer.
            The Local Hazard Map presented in Plan BF03 is to supersede the SPP broadscale mapping
            attributed to the site and should be used to guide the formulation of appropriate site-based bushfire
            management measures for the proposal.
