      12.2          address whether any of the wetlands surrounding the site are dependant on surface or
                    groundwater flows and whether construction or operation of the development will
                    change the hydrology of the site to the extent that the development is likely to affect
                    the function and any vegetation composition of the wetlands; and
      12.3          recommend mitigation and management strategies to reduce the extent of the
                    predicated impacts to the National Park and Wetland.
13.   Bushfire Impact on Design and Vegetation Retention
      The potential for bushfire to impact the site from the National Park needs to be assessed. The
      results of this assessment may detail required setbacks from vegetation and therefore may
      significantly impact upon vegetation clearing and setbacks from bushfire prone vegetation in
      the National Park and also within the site and its proposed retained vegetation. No design
      elements have been provided to indicate that the proposed dwelling will be capable of
      withstanding bushfire given the proximity to the adjacent vegetation or the proposed
      landscaping and retained vegetation.

      The applicant is to submit a Bushfire Hazard Assessment and Bushfire Management Plan for
      the site that includes an assessment of all lands and vegetation within a minimum of
      100mradius (in all directions) of the site.

      The bushfire management plan must recommend specific measures to reduce the impact of
      wildfire attack on the site. This should include but not be limited to recommendations regarding
      fire breaks to adjoining vegetation, access for fire fighting appliances, landscaping treatments
      and levels of construction as per AS3959: The Construction of Buildings in Bushfire Prone
      Areas.

      The Bushfire Hazard Assessment and Bushfire Management Plan must demonstrate
      compliance with the State Planning Policy Guidelines 1/03: Mitigating the Adverse Impacts of
      Flood, Bushfire and Landslide. Information to be submitted includes:
              i.      A site specific calculation of the bushfire hazard score(s) for the site using the
                      calculation methodology in the State Planning Policy Guidelines (Bushfire
                      Component);
             ii.      An assessment of the proposal against State Planning Policy Guidelines (Bushfire
                      Component);
             iii.     A quantitative assessment of predicted bushfire behaviour including calculation of
                      predicted Fire Intensity using McArthur’s Equation, Rate of Spread, Flame Length
                      using MacArthur’s Equation and radiant heat flux using a recognised model i.e. the
                      View Factor Model or the Leicester Model. Calculations should be based on an FFDI
                      of 50 (Sunshine Coast) and maximum predicted fuel loads. These modelled results
                      should be used to determine appropriate setbacks;
          iv.         A qualitative assessment including discussion of past fire behaviour / history, any
                      prescribed burning undertaken on the site or adjoining sites, likely fire paths, site
                      factors that would minimise or maximise fire behaviour, fuel arrangement and loads,
                      potential ignition points, fire run distances towards houses (or proposed house
                      sites), slopes and any other matter considered important regarding the issue;
             v.       A Bushfire Management Plan prepared in accordance with Appendix 8 of the State
                      Planning Policy Guidelines 1/03: Mitigating the Adverse Impacts of Flood, Bushfire
                      and Landslide; and
          vi.         A person with experience in assessing the risk of wildfire must undertake the
                      assessment against the State Planning Guidelines and to prepare the requested
                      Bushfire Management Plan. It is also recommended that the applicant consult with
                      the local Fire Brigade to discuss the risk of wildfire on the subject site and the
                      immediate environs.
