                 33.    A Geotechnical Engineer or similar qualified expert must 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 must be incorporated into the design
                        and construction of the proposed development.
                        Erosion and Sediment Control
                 34.    Prescribed Water Contaminants (as defined in the Environmental Protection Act 1994)
                        must not be released from the site, or be likely to be released should rainfall occur,
                        unless all reasonable and practicable measures are taken to prevent or minimise the
                        release and concentration of contamination. These measures must include as a
                        minimum, but are not limited to, the following:
                        34.1. Ensure non essential exposure of soil is prevented by: restricting the extent of
                              clearing to that necessary for access to, and safe construction of, the approved
                              works; protecting vegetation in all other areas of the site; and by minimising the
                              duration of soil exposure by:
                                34.1.1.   staging the works to minimise the area of soil exposed at any one time;
                                34.1.2.   effectively stabilising cleared areas prior to rainfall if works are delayed
                                          or works are not intended to occur immediately. See E&SC Advice
                                          Note 2;
                                34.1.3.   effectively stabilising areas at finished level without delay; and
                                34.1.4.   effectively stabilising steep areas, such as stockpiles, batters and
                                          embankments, which are not being actively worked and prior to
                                          rainfall.
                        34.2. Where it is not feasible to effectively stabilise cleared areas of exposed soil, such
                              as areas being actively worked, implement a full suite of erosion and sediment
                              controls to minimise erosion and maximise sediment capture in those areas; and
                        34.3. In areas of exposed soil where it is not feasible to either effectively stabilise the
                              surface or implement a full suite of erosion and sediment controls, for example in
                              the areas being actively worked and where the implementation of some erosion
                              and sediment controls would impede construction activities, ensure contingency
                              measures are available on site and are implemented, prior to rain, to minimise
                              erosion and maximise sediment capture;
                        34.4. Effectively stabilise all stockpiles, batters and embankments without delay. Where
                              it is not feasible to effectively stabilise a stockpile, batter or embankment, such as
                              areas being actively worked, ensure that sediment controls are installed and
                              surface stormwater flows are managed such that erosion of stockpiles, batters or
                              embankments is not caused by concentrated stormwater flows;
                        34.5. For all works or other disturbances undertaken within waterways (including
                              riparian areas) ensure;
                                34.5.1.   prior written approval from the relevant consent authority exists; and
                                34.5.2.   Work within waterways must only be: undertaken during dry weather;
                                          be promptly rehabilitated conforming to the natural channel form,
                                          substrates and riparian vegetation as far as possible; and be
                                          undertaken in accordance with Best Practice Erosion and Sediment
