SUPERSEDED Decision Notice OPW25 0042 · OPW25/0042

               27.    All frontage works must match neatly with existing road and verge/footpath features.
                      Additional works beyond the frontage may be required to provide an acceptable transition to
                      existing road and verge/footpath profiles.
               28.    Electrical conduits or other services proposed to be installed within existing and proposed
                      road reserves under existing sealed carriageways, concrete pathways, concrete/sealed
                      driveways or significant vegetation must be installed by boring. Trenching is not permitted,
                      unless specifically approved by Council.
                      Earthworks and Retaining Walls
               29.    All earthworks shall be undertaken in accordance with the provisions of AS 3798 Guidelines
                      on Earthworks for Commercial and Residential Development, with geotechnical testing
                      undertaken in accordance with Section 8 of the Standard, and to a minimum of ‘Level 1’ as
                      defined in Appendix B. Test results as required by AS 3798, and a certificate of quality and
                      uniformity of fill shall be provided by a RPEQ and submitted to Council prior to Council signing
                      the Plan of Survey.
               30.    All earthworks and associated batters/retaining structures, both above and below ground
                      level, both temporary and permanent, must be contained entirely within the subject site
                      unless written permission from the respective landowner(s) is provided to Council.
               31.    Fall protection must be provided to retaining walls that are over 1m high.
               32.    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
               33.    Appropriate scour protection must be provided at the outlet of all stormwater pipes including
                      temporary outlets.
               34.    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).
               35.    Construction of all internal stormwater drainage works must comply with the relevant
                      section/s of Australian Standard AS/NZS 3500.3.
               36.    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.
                      Bioretention Basins – Construction
               37.    During construction and establishment of the bioretention devices, the supervising RPEQ
                      must ensure that the device was constructed in accordance with the document Construction
                      and Establishment Guidelines: Swales, Bioretention Systems and Wetlands (Water by
                      Design, 2009) and that the forms contained in section 3.15 including the associated
                      supporting information and data are completed. These forms and certification from the RPEQ
                      that the device has been constructed in accordance with the Construction and Establishment
                      Guidelines: Swales, Bioretention Systems and Wetlands (Water by Design, 2009), all
                      conditions of approval, and the approved engineering drawings must be submitted to Council
                      prior to commencement of use.
