                 2.1.1.      Minimum design levels
                 Noosa Shire Council specifies minimum flood levels and flood immunity requirements in table 8.2.6.4 of the
                 Flood Hazard Overlay code (Noosa Plan 2020). These minimum design levels seek to manage risk to people
                 and property (performance objective PO1) and are summarized in Error! Reference source not found.
                 below. The proposed development’s floor level is set at 109.230 which is at the existing floor level according
                 to LIDAR data. According to levels obtained from the Six Mile Creek flood study, the maximum 1% AEP
                 (2100) DFE level within the building area is 108.9m AHD. Therefore, the proposed floor level meets the
                 minimum design level described in Table 2-1, and meets acceptable outcome A01 for the performance
                 objective (P01).
