                             to avoid damaging of the filter media or subjecting the filter media to
                             excessive sediment loads.
                    64.2.5   Are provided with a free-draining outlet from the sub-soil drainage
                             system.
         65.   All stormwater quality treatment devices must be maintained in accordance with a
               Maintenance Manual prepared for the development by a qualified person and
               submitted to Council prior to the issue of any Development Permit for Operational
               Works. The Maintenance Manual must include:
               65.1 A plan showing the location of the individual components of the system
               65.2 For proprietary products the manufacturer’s data and product information
                    sheets
                    65.2.1   For bioretention basins reference to the Water By Design
                             Maintaining Vegetated Stormwater Assets and Rectifying vegetated
                             stormwater assets
               65.3. Location of inspection and monitoring points shown clearly on the plan
               65.4. A schedule or timetable for the proposed regular inspection, maintenance
                     and monitoring of the devices.
               65.5 For proprietary products a maintenance contract of a minimum 10 years to
                    demonstrate that the proprietary product shall be maintained as per the
                    manufacturers specifications.
               65.6 Details of the location and method for maintenance of any proprietary
                    products to demonstrate that collected pollutants and nutrients shall be
                    disposed of in accordance with relevant legislation.
               Records of all maintenance activities undertaken must be kept and made available
               to Council upon request.
         72.   The fire-fighting demand on Unitywater’s water supply system from the
               development must comply with Unitywater requirements and industry standards.
    C.   Delete conditions 44, 45 and 80.
    D.   Include the following new condition
         81.   Any proprietary stormwater quality improvement device included to achieve the
               required stormwater quality Management Objectives specified in Section 4 of the
               Girraween Stormwater Management Plan, must demonstrate only be granted an
               Operational Works Approval on the following provisions:
               a.   A suitably qualified and experienced professional must provide independent
                    verification that the parameters within the node for the device in MUSIC
                    modelling have been tested and verified as per Stormwater Australia (2018)
                    Stormwater Quality Improvement Device Evaluation Protocol. Version 1.2
                    December 2018 to achieve the predicted outcomes in the MUSIC model for
                    the development. For the purpose of this condition, the suitably qualified and
                    experienced professional must be able to demonstrate a minimum 10 years
                    urban stormwater testing and modelling experience and be verified in writing
                    by Stormwater Australia as having an appropriate reputation and track record
                    within the stormwater industry to provide such independent advice.
               b.   Where testing to achieve the certification of the proprietary stormwater
                    quality improvement device is from an area with rainfall intensities and
                    patterns that are statistically inconsistent with the region of the Noosa Shire
                    that the device is to be installed, and / or the size of the development the
                    device has been tested on is more than 2500m2 smaller than the


                                                                                    Page 15 of 21
