12. Ground Water and Surface Water Impacts

    The Applicant has been previously requested by Council (30t`' April 09) to provide detailed
    assessment of the variations to and the impact upon the water quality and quantity on both the
    surface subsurface water drainage. This has not been provided. It is only once this information is
    provided that an adequate assessment on the flora and fauna on the wetland on the site and that
    in the adjacent National Park can be assessed.

    Applicant is to provide a detailed assessment of the variations to and the impact upon the water
    quality and quantity on both the surface subsurface water drainage and conduct a detailed
    assessment as the potential impact the disturbance will have upon the flora and fauna both within
    and adjacent to the site.

    12.1    provide an explanation as to the type and cause of the impacts predicted to the wetland
            and national park as a result of development of the site; and
    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.

Response:
A Ground Water/Surface Water Impacts response has been prepared by Litoria Consulting and
included in Attachment 5.        This correspondence confirms that the proposed development
appropriately manages    impacts  on surface runoff and quality to mitigate potential impacts on
downstream wetlands and that the retention of native vegetation and rehabilitation of disturbed areas
proposed will provide a natural buffer between the house and downstream wetlands.

13. Bush fire Impact on Design and Vegetation Retention

    The potential for bush fire 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 bush fire 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 Bush fire Hazard Assessment and Bushfire Management Plan for the
    site that includes an assessment of all lands and vegetation within a minimum of 100m radius (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 Bush fire Prone Areas.

    The Bush fire Hazard Assessment and Bush fire Management Plan must demonstrate compliance
    with the State Planning Policy Guidelines 1/03: Mitigating the Adverse Impacts of 'Flood, Bush fire
    and Landslide. Information to be submitted includes:
