6             NOOSA PLAN – COASTAL PROTECTION AND SCENIC AMENITY
              OVERLAY CODE
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.

 Where a coastal building line exists on a lot, all buildings, structures and

 site, other than—
 a)       uncovered and unenclosed cantilevered balconies that do not extend
          greater than 3 metres seaward of the coastal building line; and
 b)       are setback a minimum of 6 metres from the seaward boundary (see
          Figure 8.2.4.4).
 Editor's Note—State coastal building lines are identified on the Coastal
 Protection Overlay Maps. State coastal building lines are declared under
 the Coastal Protection and Management Act 1995.
