109. Prior to the release of the plan of survey, the supervising RPEQ must certify must certify
     that all hardstand areas of the development drain to a bioretention device designed and
     constructed in accordance with all relevant conditions of this approval, the Water by
     Design Bioretention Technical Design Guidelines, relevant aspects of the IPWEAQ
     Standard Drawing WSUD-drawing series and Construction and Establishment
     Guidelines: Swales, Bioretention Systems and Wetlands (Water by Design, 2009).
      Bioretention Devices - Landscaping
110. Landscape plans must include a mixture of at least five of the following species for
     planting in the bioretention basin extended detention surface at a minimum density of 8
     plants/m2:
      e.    Carex appressa
      f.    Carex fascicularis
      g.    Ficinia nodosa
      h.    Juncus usitatis
      i.    Lomandra longifolia
      j.    Ghania sieberiana
111. Landscape plans for the areas surrounding the bioretention basin filter media footprint
     must be arranged to minimise shading to the filter media footprint are. Suitable plants
     include the following:
      k.    Carex appressa
      l.    Carex fascicularis
      m.    Ficinia nodosa
      n.    Juncus usitatis
      o.    Lomandra longifolia

      s.    Themada triandra
      t.    Cymbopogan refractus
      u.    Melaleuca thymifolia
112. 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.
113. 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.
114. 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.
