Minor Change Existing Approval - 132007.2399.03 (AS PUBLISHED)

               Roof Water
               38.    Roof runoff from any new dwelling/building shall be directed to a rainwater storage system
                      or tank that is installed to ensure water from the rainwater storage system or tank is used for
                      external uses (such as watering gardens, irrigation, ornamental ponds, water features,
                      topping-up swimming pools, outdoor cleaning, etc) and for internal (ground floor) use in
                      washing machine cold taps and toilet cisterns. All rainwater tanks are to be designed and
                      installed in accordance with the Queensland Development Code (QDC) current at the time
                      of building approval, and shall be part of the plumbing application for approval. The location
                      and capacity of the tanks shall be clearly shown on the plans submitted for Building Works
                      approval and any overflow shall be directed to the stormwater drainage system.
               Stormwater Management
               39.    A Stormwater Management Plan (SMP) for the construction and operational phase of the
                      development shall be submitted in conjunction with any application for a Development Permit
                      for Operational Works that demonstrates that the proposed stormwater treatment train can
                      meet the water quality objectives for the Noosa Springs development and that the lakes have
                      the capacity to treat the runoff from this additional development. Experts in the relevant field
                      shall prepare the SMP.
               40.    The Applicant shall be responsible to oversee that the Council approved SMP is
                      implemented. The Applicant shall engage a suitably qualified and experienced environmental
                      engineer with RPEQ accreditation to recommend corrective actions in the event of any
                      breach of the SMP that is likely to result in a public health risk, environmental harm and/ or
                      non- compliance with the objectives of the SMP. The Applicant shall implement all corrective
                      actions recommended by the environmental engineer/environmental scientist, unless
                      directed otherwise by Council.
               41.    All stormwater drainage shall be designed in accordance with the provisions of the Australian
                      Rainfall and Runoff (A.R.R.), and Noosa Council Standards. Pipe and channel drainage
                      systems shall be designed to cater for Five (5) year Average Recurrence Interval design
                      storm (ARI.). In all cases the major event surface flow paths shall be designed to cater for
                      the one hundred (100) year ARI.
               42.    As the site is proposed to be filled, appropriate stormwater drainage pipes shall be installed
                      within the site to collect and discharge stormwater runoff from all adjoining properties to
                      prevent additional ponding/flooding on these properties.
               43.    To ensure that polluted run-off does not enter Council’s stormwater drainage system,
                      stormwater run-off from the carparking areas and the private roads/driveways shall have the
                      first flush (the first 12 mm of rainfall or hose-down) collected in a grease/oil arrestor/gross
                      pollutant trap provided on site prior to being permitted to discharge into the lakes.
                      All other clean stormwater, such as roof water, can be collected on site and discharged
                      through a single underground drain line directly onto the golf course, bypassing the grease/oil
                      arrestor/gross pollutant trap.
                      To this end, a detailed maintenance plan shall be prepared for the proposed grease/oil
                      arrestors/gross pollutant trap, which shall be submitted to the Council for approval prior to
                      obtaining a Development Permit for Operational Works.
                      The approved maintenance plan shall be incorporated in the Community Management
                      Scheme for the development and a copy of this shall be provided for Council’s records prior
                      to commencement of the approved Use.
                      A Development Permit for Building Works shall not be granted until a Development Permit
                      for Operational Works has been issued in regard to the drainage scheme.
               44.    All site stormwater drainage shall be by means of a gravity system.
