2019-09-30 Special Meeting Agenda - Item 1 - Attachment 4 - Court Judgement

                              (c)      a 2m wide pathway connection to the existing commercial development in the
                                       southern part of the subject site
                              Stormwater Drainage
                      21.     The site must be provided with a stormwater drainage system connecting to a lawful
                              point of discharge. The works must be undertaken in accordance with an Operational
                              Works approval.
                      22.     A Stormwater Management Plan must be submitted for approval as part of an
                              Operational Works application. The plan must address the management of stormwater
                              quantity and quality and must be generally in accordance with the Stormwater
                              Management Plan (SLR, 23 March 2018) being exhibit 64 in appeal 4066 of 2017 with
                              the following specific modifications.
                              (a)      The development shall include a 3kL tank to be provided to collect and reuse roof
                                       runoff from each unit, and a 200kL tank must be provided to collect and reuse
                                       runoff from the motel.
                              (b)      The detention tanks must be sized to ensure no increase in peak discharge from
                                       the site for all events from 63% AEP to 1% AEP inclusive.
                              (c)      The first application for Operational works for the development must include a
                                       Music Model prepared in accordance with the Water by Design Music Modelling
                                       Guidelines, and which demonstrates that the development layout proposed in the
                                       Operational Works application will achieve the State Planning Policy Water Quality
                                       Objectives of 80% Reduction in Total Suspended Solids, 60% Reduction in total
                                       Phosphorous, and 45% reduction in Total Nitrogen. The results of the MUSIC
                                       modelling must also demonstrate that the developed site will discharge less annual
                                       loads of Total Nitrogen, Phosphorous and Total Suspended Soils respectively
                                       compared to the pre-development scenario.
                              (d)      The pervious percentage of the development must be consistent with the pervious
                                       percentage derived from attached Simmonds & Bristow Drawing 1108-155C-01-
                                       02 Rev C (13 January 2012). RPEQ certification must be submitted to Council
                                       that states the pervious percentage of the final development is consistent with that
                                       derived from the Simmonds & Bristow Drawing.
                              (e)      The configuration of the stormwater quantity and quality components of the
                                       stormwater management system must be generally in accordance with Figure
                                       SW-1 (attached) unless otherwise agreed by Council.
                              (f)      The bioretention system must be formed with batters and not walls and include a
                                       minimum width of 5 metres.
                              (g)      Unless directed otherwise by Council, the detention tank will be covered.
                              (h)      The plan shall include detailed information in relation to the following aspects of
                                       the design of the bio-retention system:
                                       (i)     calculations of underdrainage requirements for the bio-retention system;
                                       (ii)    filter media composition requirements;
                                       (iii)   a schedule which details how the construction, establishment, certification
                                               and various inspections associated with each treatment measure relate to
                                               other civil works;
                                       (iv)    Where bioretention basins are used for stormwater quality treatment, the
                                               design must be consistent with all aspects of the Water by Design (2014)
