                 The development is approximately >60m away from the centreline of the waterway and is within existing
                 cleared areas of lowest ecological value. The proposed development does not necessitate the removal of
                 vegetation within the riparian zone and is in accordance with acceptable outcomes outlined in the
                 Biodiversity, Waterways and Wetlands Overlay code. Therefore, the proposed development satisfies all
                 performance objectives within the code. Refer to Appendix C for further details.




                 2.3.       Recommendations
                 Colliers proposes the following recommendations regarding managing stormwater for the proposed
                 development:

                     1.   According to levels obtained from the Flood Information Certificate, the maximum 1% AEP (2100)
                          DFE level within the building area is 108.9. The minimum floor level of the building shall be >
                          RL109.2 m AHD, in accordance with table 8.2.6.4 of the Flood Hazard Overlay Code (Noosa Plan
                          2020). The proposed development’s floor level is set at 109.230 and is satisfactory.
                     2.   As existing swales are impacted by the extent of proposed earthworks, additional earthworks are
                          recommended to ensure that water free drains from the site. It is recommended that drainage
                          swales are re-established at the site as shown in Figure 2-7.
                     3.   The proposed development will increase impervious area by 2.5x, including an additional ~1600m 2
                          of roof area. It is recommended that additional rainwater tanks are installed to reduce potable
                          water use at the site if feasible.
