         As detailed in Section 7.1, the outdoor noise limit can range between SOdBA                     LAmax and SSdBA

         LAmax depending on the fa ade attenuation provided by a normal and naturally-ventilated dwelling

         (i.e. open windows). For this assessment, an outside noise limit range of SOdBA to SSdBA has
         been adopted, i.e. a SdBA-10dBA noise reduction from outside to inside.



         There are some exceedences predicted over the transient noise limits, particularly for:


               .   SRV travel at Area B (exceedance of the SOdBA criterion            by 2dBA, but complies with the
                   SSdBA criterion);


               .   MRV accelerate at Area A (exceedance of the SOdBA criterion by 10dBA);


               .   MRV accelerate at Area C (exceedance of the SOdBA criterion             by 3dBA, but complies with
                   the SSdBA criterion);


                   MRV accelerate at Area C (exceedance of the SOdBA criterion             by 2dBA, but complies with
                   the SSdBA criterion);


                   HRV engine start at Area B (exceedance of the SOdBA criterion by 4dBA, but complies with

                   the SSdBA criterion);


               .   HRV accelerating at Area A (exceedance during the day, evening, and night);


               .   HRV travel at Area B (exceedance of the SOdBA criterion by 4BA);


               .   Air brakes at Area B (exceedence during the evening and night);


               .   RCV Waste handling at Area B (exceedence during the evening and night); and


               .   Forklift use at Area B (exceedance of the SOdBA criterion by 6dBA)



         We    noted   that where     there   are   exceedances of the SOdBA criterion          by   up to    SdBA, these
         exceedances will still comply with the SSdBA criterion with residential windows partially open.

         It can be seen that there is an exceedence of SdBA during the day and 9dBA during the evening

         for HRVs      accelerating   at the   entrance   of the service     and   loading    to   the west. The       noise

         exceedence at night is approximately 22dBA. These exceedences are also expected to occur at

         northern residences along Woodland Drive with HRVs pass-bys.



         The IGA Supermarket operator has stated that HRV deliveries from IGA warehouses would                         occur


         once a    day, typically   between 8am and       noon   on   week days only. HRV deliveries will not occur

         during evening and night periods (6pm to 7am).


         An exceedence of SdBA during the daytime can be considered to be                 insignificant. A truck passby
         is   expected to only occur over a brief period of approximately 5 to 10 seconds and would be
         similar to normal occasional truck passbys along the local Council roads.



        Transient noise activities     exceeding noise limits during the evening are Air brake use and RCV
         Waste handling activities. Activities at the service and loading bay area will only occur during the
