Delegated Report - Code - Planning OPW26 0094 (As Published) · OPW26/0094

                      Treated material must undergo verification testing at the rate of one sample per 250m3
                      throughout the duration of the excavation phase of the development. The verification testing
                      must be undertaken by a qualified person in accordance with the Queensland Acid Sulfate
                      Soil Technical Manual: Soil Management Guidelines v4.0, and the results must be submitted
                      to Council for appraisal when requested during construction and prior to commencement of
                      use and must demonstrate that the material has been adequately neutralised.
                      Certification of the verification results for compliance with this condition must be provided by
                      a suitably qualified Geotechnical Engineer prior to the issuing of the certificate of
                      classification for the dwelling.
               16.    Fall protection must be provided to retaining walls that are over 1m high.
               17.    Slope and batters are a maximum grade of:
                      a.      1 in 6 where in proximity to waterbodies;
                      b.      1 in 4 for grassed areas;
                      c.      1 in 3 for planted areas; and
                      d.      1 in 2 for combined structural engineering and planting solutions.
               Stormwater Drainage
               18.    Appropriate scour protection must be provided at the outlet of all stormwater pipes including
                      temporary outlets.
               19.    Works associated with this permit must not adversely impact on the existing drainage
                      conditions on other properties (e.g., by blocking or interfering with natural overland flows).
               20.    Prior to the completion of the development, all site surfaces must be effectively stabilised
                      using methods which have achieved effective short-term stabilisation and which will continue
                      to achieve effective stabilisation in the medium- to long-term (refer to E&SC Advisory Notes).
                      For the purpose of this condition, an effectively stabilised surface is defined as one that does
                      not, or is not likely to result in visible evidence of soil loss caused by sheet, rill or gully erosion
                      or lead to sedimentation, or lead to water contamination
               Erosion and Sediment Control
               21.    Prescribed Water Contaminants (as defined in Schedule 10 of Environmental Protection
                      Regulation 2019) must not be released from the site or to waters within 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.
               22.    Sediment and erosion control measures must be in place prior to works commencing. If such
                      measures are not in place or are not satisfactory, “on the spot” fines may be issued. Such
                      fines can be issued if sediments from the site are found to enter or have the potential to enter
                      Council’s stormwater system, natural waterways, any downstream stormwater filtration
                      system or adversely impacting on other properties. The sediment and erosion control design
                      and measures have NOT been approved, it is the site's Supervising Engineer who is
                      responsible for ensuring that the sediment and erosion control measures have:
                      a.      been duly designed by an RPEQ or CPESC and constructed in accordance with "best
                              practise" methods;
                      b.      been revised by an RPEQ or CPESC to address the issues raised by changes in the
                              projected construction schedule and/or methods;
                      c.      been revised to address predicted rainfall events; and
                      d.      achieve the desired environmental outcomes.
                      Council may request further controls to be installed should thew implementation measures
                      be found inefficient.
