                      Landscaping Works
               49.    Landscape works must be supervised, undertaken and certified by qualified persons*. All
                      works must be completed in accordance with this Decision Notice.
                      (* Refer to Advisory Note)
               50.    Landscape works must:
                      a.      Delineate all planting to grassed area interfaces with a hard permanent edge.
                      b.      Ensure amenity or sales signage and ancillary infrastructure is not installed within the
                              road reserve.
                      c.      Ensure permanent irrigation is not installed within the road reserve
                      d.      Ensure a minimum of 4m3 of friable soil is available for each tree planted.
                      e.      Ensure mulch is aged, comprised of leaf and limb material of varying sizes, free of
                              foreign matter including anthropogenic waste, rock, soil/sediment contamination and is
                              applied to all planting areas to ensure a minimum 100mm depth once settled.
               51.    Street trees must:
                      a.      Meet Specifying Trees – a guide to assessment of tree quality (NATSPEC) or updated
                              equivalent standard.
                      b.      Be located in accordance with engineering requirements for safe vehicle and
                              pedestrian sight lines.
               52.    Turfed areas must be free of pest, diseases and weeds and level with adjoining surfaces.
                      Site Stability and Soil Quality
               53.    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.
                      d.      1 in 2 for combined structural engineering and planting solutions.
               54.    Soil for landscaping must provide for healthy and sustained site specific vegetation
                      performance.
                      Environment
               55.    Prescribed Water Contaminants (as defined in the Environmental Protection Act 1994) 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.
               56.    Erosion and sediment control measures must be installed and maintained to minimise
                      erosion on the site and to minimise the export of sediment and associated pollutants from
                      the site. The erosion and sediment control measures must be designed, installed and
                      maintained in accordance with current best practice standards (refer to advisory notes).
               57.    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 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.
               Damage to Services and Assets
               58.    Any damage caused to existing services and assets as a result of the development works
                      must be repaired at no cost to the asset owner at the following times:
