                  21        Demonstrate the development is consistent with the SEQ Water Development
                            Guidelines: Development Guidelines for Water Quality Management in Drinking
                            Water Catchments 2012.


                  Issue – Stormwater
                  It is unclear whether there is adequate fall between the underdrainage of the bioretention
                  basin and the receiving stormwater network.
                  Information Required
                  22        Provide a preliminary drainage plan to demonstrate there is adequate grade
                            between underdrainage of the bioretention basin and receiving stormwater network.


                  Issue – Stormwater
                  The proposal shows the bioretention basin surrounded by retaining walls. This design does
                  not meet the objective of integrating the water treatment with the surrounding use and it is
                  unclear how the bio retention basin will be accessed for maintenance.
                  Information Required
                  23        Demonstrate that the footprint allocated for the bio retention basin includes sufficient
                            area for inclusion of batters from the surrounding area to the surface of the filter
                            media consistent with the Water By Design Bioretention Basin Technical Design
                            Guidelines (in particular Table 9).
                  24        Demonstrate how the bio retention basin will be accessed for maintenance
                            purposes.


                  Issue – Water Re-use
                  Specific outcome O3 of the Water Sensitive Design Code requires that captured water is
                  utilised for all non-potable uses on site.
                  Information Required
                  25        Demonstrate how O3 of the Water Sensitive Design Code is intended to be
                            achieved.

                  End of Information Request

                  Under the provisions of the Sustainable Planning Act 2009, you have three options
                  available in response to this Information Request. You may give the assessment manager
                  (in this instance Council) and each referral agency (if any):

                  (a)       all of the information requested; or
                  (b)       part of the information requested together with a letter asking the assessment
                            manager and each referral agency to proceed with the assessment of the
                            application; or
                  (c)       a letter;
                            (i)      stating that you do not intend to supply any of the information requested; and
                            (ii)     asking the assessment manager and each referral agency to proceed with
                                     the assessment of the application.
