                      The site is located within the Coastal Protection and Scenic Amenity Overlay mapping for the Noosa
                      Plan 2020, and the proposed development will be assessed by Noosa Shire Council against the
                      Coastal Protection and Scenic Amenity Overlay Code (the Code). Table 6-1 provides responses to
                      PO1 to PO4 of the Code.
                      In summary, the reassessment has shown that the site is not located within the erosion prone area
                      and the proposed development:

                                   maintains coastal processes including erosion and accretion processes, enabling these natural
                                    functions to continue;
                                   maintains the protective function of coastal resources including vegetation and dunes to mitigate
                                    risks associated with coastal erosion; and,
                                   ensure natural beach values, sea turtles and sea turtle nesting areas are protected from the
                                    impacts of development.
