   35.   All stormwater quality treatment devices must be maintained in accordance with the
         Water by Design (2009) - Maintaining Vegetated Stormwater Assets (Version 1). A
         copy of this document must be retained on the site together with the approved
         Operational Works drawings for the stormwater quality treatment system and a
         detailed life cycle costing of the system attached as an addendum. Records of all
         maintenance activities undertaken must be kept and made available to Council upon
         request.
   36.   Any proposed Community Management Statement required for the development
         must include the Water by Design (2009) – Maintaining Vegetated Stormwater Assets
         (Version 1) document and must include the full cost of maintaining the system in
         accordance with that document.
   37.   The applicant must submit plans for approval with the operational works application
         for the inclusion of educational signage or stencilling to be incorporated within the
         development to ensure patrons are reminded to minimise waste and place it in bins.
         Stormwater Harvesting
   38.   Operating underground stormwater harvesting tanks must be provided for the
         development. The tanks must be provided in accordance with an Operational Works
         approval and must include in particular:
         a.   a total tank capacity of a size suitable to maintain expected non-potable and
              outdoor uses for a 2 month period without rain.
         b.   a minimum catchment of 50% of the building roof area.
         c.   re-use of harvested rainwater for internal non-potable uses and outdoor uses.
   39.   Certification must be submitted to Council from a qualified person which certifies that
         the rainwater collection tank/s and associated reticulation has/have been installed in
         accordance with the requirements of this Decision Notice.
         Acid Sulfate Soils
   40.   All works must be carried out in accordance with an Acid Sulfate Soil and
         Groundwater Management Plan for the development prepared by a suitably qualified
         person and referenced in a Development Permit for Operational Works. The Acid
         Sulfate Soil and Groundwater Management Plan submitted with the application for
         Operational Works must detail:
         a.   Management necessary for the proposed filling to avoid any impacts of the
              Potential Acid Sulfate Soils identified on the site – in particular impacts related
              to compacting Acid Sulfate Soils into the groundwater table and releasing water
              contaminants.
         b.   design measures necessary to prevent any oxidation of the potential acid
              sulfate soils or transfer of acid sulfate soil leachates via dewatering of
              groundwater through underground pipe bedding material.
         c.   Any other matters necessary to prevent the oxidation of potential acid sulfate
              soils or release of Acid Sulfate Soil related water contaminants.
   41.   All waters, including stormwater runoff, groundwater seepage and leachate from acid
         sulfate soils must achieve the following quality prior to release from the site:
         a.   a pH range of 6.5-8.5 pH units
         a.   50mg/L maximum total suspended solids concentration
         b.   0.3mg/L maximum total iron concentration
         c.   0.2mg/L maximum total aluminium concentration
         d.   no visible plume at either the point of release from the site or within a waterway

                                                                                 Page 12 of 64
