                                                                                       2007/2399



Acid Sulfate Soils
                                                                                            3
66.   As the site is located below the 5m AHD, any excavation works consisting of 100m or greater
                                                   3
      and/or any filling works consisting of 500m or greater and with an average depth of 0.5m or
      greater will need to be carried out in accordance with State Planning Policy 2/02 Planning and
      Managing Development Involving Acid Sulfate Soils. In this regard appropriate testing and
      supporting documentation prepared by a suitably qualified specialist shall be submitted to
      Council for approval prior to obtaining a Development Permit for Operational Works.
67.   As the subject site is likely to contain Acid Sulfate Soils, Council wishes to make the applicant
      aware of their obligations in terms of good environmental practice, which requires that Acid
      Sulfate Soils:-
         should not be removed from the site,
         should not be disturbed, if possible, and
         should be treated and neutralized on site where required.
      In the event that Acid Sulfate Soils are removed from site and forwarded for disposal at one of
      Council’s landfill sites, Council may:-
         refuse to accept such soil, or
         treat and neutralize the soil and charge such costs for soil testing and remediation to the
          applicant and or developer of the site.
Site Stability
68.   A Geotechnical Engineer or similar qualified expert shall assess the soil condition on site,
      determine the soil classification, establish whether any measures are required to protect the
      stability of adjoining buildings and/or structures and/or land, and make recommendations on
      the type of foundation system(s) best suited for the proposed development. The
      recommendations of this report shall be incorporated into the design and construction of the
      proposed development.
Erosion and Sediment Control
69.   Any person acting on this permit shall prevent erosion and sediment export from leaving the
      site. Site control measures such as silt fencing, controlled gravel access to the site and
      controlled disposal of waste, will be necessary.
      In this regard plans detailing the methods of controlling erosion and sediment are required to
      be submitted to the Council for approval prior to obtaining a Development Permit for
      Operational Works.

Vegetation Protection & Preservation
70.   All Class 1, Class 2 and Class 3 pest plants declared under the Land Protection (Pest and
      Stock Route Management) Act 2002 are to be controlled on the site prior to Council
      endorsement of the plan of survey. In this context “controlled” shall mean, for class 1 and 2
      pests, completely eradicated. For class 3 pests it shall mean removal of the plants where they
      threaten environmentally significant areas of the site such as riparian zones and areas of
      natural vegetation. Where class 3 plants are removed as a result of this condition and there is
      not sufficient natural regeneration of native species, the areas shall be replanted with endemic
      native species so that a sustainable natural ecosystem is restored.
      Council’s Conservation Management Supervisor will not inspect the site until 30 days after the
      weed treatment and replanting is complete
