               13.    Where landscaping/garden beds are proposed adjacent to the bioretention basin, or where
                      the basin is located adjacent to naturally forested areas, a 900mm deep root barrier must be
                      installed to the interface between the landscape/garden/forest area and the bioretention
                      basin to prevent root intrusion to the biobasin infrastructure.
               14.    Landscaping to the surface of the bioretention basin filter media area must not commence
                      until 80% of building work within each contributing catchment is complete or after 3 years,
                      whichever occurs first. An uncompleted works bond of 150% of the value of the planting to
                      the surface of the bioretention basin filter media area must be provided to Council prior to
                      the release of the Plan of Survey.
               15.    Where required, mulch within the batters of bioretention basins must be installed in a manner
                      that it will not escape into receiving stormwater drainage infrastructure or water courses.
                      Bioretention Devices - Education
               16.    The development shall be provided with approved permanent signage to educate the public
                      on the function of the bioretention basin. The wording for the signage for each bioretention
                      basin is to include: “BIORETENTION BASIN - This bioretention basin reduces the pollution
                      of our waterways by reducing the amount of heavy metals, litter, suspended solids, and
                      nutrients discharged to Six Mile Creek”.

                      Site Stability
               18.    Prior to the completion of the development, all site surfaces must be effectively stabilised.
                      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.
