Final Judgment - Court Order Approval MCU16/0153 REC16/0041

      (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)
                    Bioretention Technical Design Guidelines Version 1.1) Healthy Waterways
                    Ltd Brisbane, including for free draining outlets to and from the bioretention
                    basins, and include completed copies of the design check and
