                                proposed facilities are to be located to ensure compliance with AS2890.3 with
                                regard to their access, location and design.
                        d.      End of trip facilities involved 50 lockers, 10 showers and change rooms.
                        Condition 45a is imposed pursuant to s145 of the Planning Act 2016 being non-trunk
                        infrastructure.
                        Stormwater Drainage
                 46.    Prior to the lodging of a development application for Operational Works, provide and
                        have endorsed by Council updated architectural plans, preliminary engineering plans,
                        and Stormwater Management Plan, which addresses the following:
                        a.      Acceptance of all external catchments
                        b.      Provide sizing and nominate the locations of roofwater harvesting tanks. The tanks
                                are to be sized to provide 80% reliability to supply water for landscape irrigation
                                and pool top up.
                        c.      Provide a method of removal of gross pollutants from all surface runoff (eg litter
                                baskets)
                        d.      Provide treatment of internal site runoff such that the pollutant removal
                                requirements of AO6.1 and AO6.2 of the Water Quality and Drainage Code are
                                achieved prior to discharge to surface waters or infiltration to groundwater. Provide
                                MUSIC modelling to demonstrate this will be achieved by the proposed stormwater
                                treatment train.
                        e.      Provide in-situ hydraulic conductivity testing at the locations and depths nominated
                                for Rapid Infiltration Pits and demonstrate that the assumptions regarding
                                infiltration rates will be achieved. If not achievable, provide a revised design.
                        f.      Ensure the proposed method of stormwater management achieves no net
                                reduction of rainwater infiltrating the sand dunes beneath the site. This may be
                                achieved either by infiltrating all flows up to the 10%AEP or by alternative
                                measures designed and managed in accordance with a groundwater recharge and
                                discharge management plan prepared by a suitably experienced and qualified
                                groundwater hydrologist. The groundwater recharge or discharge must
                                demonstrate that the development does not affect groundwater balances beyond
                                the property boundaries.
                        g.      Updated the maintenance and management plan of the Stormwater Management
                                Plan to reflect any changes.
                        All works are to be undertaken in accordance with the updated endorsed plans.
                 47.    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 the Queensland Urban Drainage Manual, and must include in particular:
                        a.      the works as generally described in the updated Stormwater Management Plan
                                required by this permit
                        b.      collection and discharge of stormwater from the external catchment through the
                                development site, including provision of an overland flowpath which accounts for
                                severe storms or severe blockage of the underground network
                        c.      provision of drainage easements over all flowpaths conveying catchments external
                                to the site, in accordance with QUDM. Easement dimensions and locations are to
                                be shown on the plans submitted with the development application for Operational
                                Works.
                        d.      the use of gravity stormwater drainage and not surcharge pits
