                         Amendments           The minimum depth of the proposed rock armor scour protection is
                                              not satisfactory.
                                              Provide an amended Proposed Crossings Layout & Details Plan
                                              prior to the prestart meeting that includes:
                                                    a.    200mm d50 rock armor scour protection to a minimum
                                                          depth of 300mm.

                         Amendments           During the 1% AEP event, stormwater overflow from Catchment 2/A
                                              will be controlled, collected and discharged within the subject site
                                              towards the fire access trail via Outlet 1/A.
                                              The design proposes to concentrate flow without returning flow back
                                              to the natural flow regime, creating the potential risk of scour about
                                              the outlet and to downstream properties (fire access trail, Giraween).
                                              Provide an amended Finished Levels Plan – Sheet 7 and Stormwater
                                              Longitudinal Sections prior to the prestart meeting that includes:
                                                    a.    an amended outlet (1/A) that returns the concentrated
                                                          flow back to the natural flow regime (i.e., sheet flow).
                                                          Council considers an acceptable solution to include a
                                                          rock energy dissipator.

               Applicant’s Request
               The applicant has requested the list of Approved Plans be amended to reflect the latest drawing
               revision.
               Assessment of Request
               The request is considered necessary to ensure that the Approved Plans reflect the works on site.
               Although not specifically requested by the applicant, the plans requiring amendment should be
