Delegated Report - Code - Planning OPW23 0179 · OPW23/0179

               •      DME Project’s Proposed Layout Ground Floor Plan Rev E (DWG# 220508-04) has been
                      updated to include a 2m wide footpath along the full length of the development frontage to
                      Gympie Terrace in accordance with Conditions 27 & 28 of MCU22/0171.




               Stormwater & Flood Hazard
               •      DME Project’s Stormwater and Surface Details Basement plan (DWG# 22058-05B Rev E) is
                      consistent with the plan referenced in Condition 31 of MCU22/0171. The plans now note that
                      the pump out system be fitted with a suitably sized battery to be located within the basement
                      plant room to run the pump in the case of a power failure. This is in accordance with AO6.5
                      of the Flood Hazard Overlay Code.
               •      LPOD is proposed via kerb adapters to Gympie Terrace in accordance with Council’s
                      Standard Drawing RS-081.
               •      Driveway is at RL 2.4 m AHD to achieve the required flood immunity in accordance with the
                      approved plans for MCU22/0171. RPEQ comment has been provided from DME Project’s
                      (DME Project’s response to IR, dated 2/3/24, page 4) confirming that the basement carpark
                      (including associated access through 126 Gympie Terrace) achieves immunity from a 1%
                      AEP event in accordance with the Flood Hazard Overlay Code and as confirmed by Council
                      during the MCU assessment.




               Earthworks
               •      An information request was sent to the applicant on 13 December 2023 requesting
                      additional amendments to the submitted Dewatering Management Plan requesting the
                      following:

               Provide an updated dewatering management plan that includes the following:
                      i. The DMP states that the shoring design is provided in Appendix C – however only the
                           civil engineering plans are provided. Include plans which show the location and type
                           of temporary shoring, groundwater spears, treatment and monitoring equipment
                           location and space requirements. Why do the structural engineering plans (provided
                           separately) only show shoring on 3 sides of the excavation? The type of CFA piling
                           (contiguous or secant) should also be stated on plan.
                      ii. Remove references to ‘steel sheet piling’ on page 10 and refer to CFA secant piling.
                           Please note that the references should reflect the proposed method, or the alternate
                           method chosen by the civil engineer.
                      iii. Update section 6.5.2 and 6.5.3 (Water Quality Monitoring) to include continuous
                           monitoring of pH and dissolved oxygen at the release point from the treatment
                                                                                                     Page 7 of 21
