                      23098/SK10          G        Concept Site Levels and Drainage Plan        14/05/2024
                                          1. The drawing is marked as conceptual and includes a note
                      Amendments
                                             advising the drawing is not to be used for construction. Provide
                                             an amended plan that is suitable for Operational Works
                                             Construction for Council approval prior to the prestart meeting.
                                          2. Prior to the prestart meeting, provide an amended plan to Council
                                             for approval that includes the frontage works required in
                                             accordance with the MCU Conditions.
                                          3. Prior to the prestart meeting, provide updated engineering plans
                                             which specifically address the following:
                                              a.   A piped solution is proposed for Lot 1 SP153798. Due to the
                                                   proposed surface levels of the development driveway, when
                                                   events exceed the 2%AEP, or when blockage of the pipe inlet
                                                   occurs, flooding/ponding on the upstream lot will occur.
                                                   Revise the design to ensure that no ponding/flooding on the
                                                   upstream lot will occur in the 1%AEP event based on design
                                                   blockage allowance for any pipe system, consistent with
                                                   QUDM.
                                              b. Provide cross and long sections and hydrologic and hydraulic
                                                 calculations for the swales proposed in the following
                                                 locations:
                                                     i.    On the eastern boundary of the development site to
                                                           convey flows from outlet 2/1 to the LPD
                                                     ii.   From the driveway low-point to the bioretention basin
                                                    iii.   On the northern and eastern boundaries of Lot 1
                                                           SP153798 to convey runoff from the external
                                                           catchment to inlet 1/1
                                              c. Provide ILs for the structures on the proposed stormwater
                                                 line and confirm what type of structure is 1/1 (headwall or
                                                 field inlet)


               CURRENCY PERIOD
               49.    The Currency Period for this development approval lapses if the development has not
                      substantially started by 10 November 2027, unless an application to extend the currency
                      period is approved by Council.
               SITE SPECIFIC CONDITIONS

                      Engineering
               51.    All necessary approvals from external service providers (e.g. Unitywater) and external parties
                      on which the development works are proposed have been obtained and a copy supplied to
                      Council.
