.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.
 Bushflre 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 Bushflre Prone
Areas.

 The Bushfire Hazard Assessment and Bushflre Management Plan must demonstrate
 compliance with the State Planning Policy Guidelines 1/03: Mitigating the Adverse Impacts of
'Flood, Bushflre and Landslide. Information to be submitted Includes:
         1.    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);
        If.    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.
