         The data shown in Table 12 together with the geometry data obtained from drawings have been

         used in the       preparation of the computer model using the Sound PLAN software.                  This software

         uses the CoRTN        198813 algorithms endorsed by Council.


         The model has been calibrated using the existing 2013 noise measurements. The model has then

         been used to predict the traffic noise level at the nearby residences for future traffic conditions. A

         comparison between current and future noise levels has been made to ascertain the noise impacts
         at the residences.

         The model has included the following assumptions:


                      .   The 18 hour traffic count will be 94% of the daily volume


                          Road surfaces in the future will be identical to the existing road;


                  .
                          Average speed of SOkm/hr for Wooodland Drive and Rufous Street;

                  .
                          Average speed of 60km/hr for David Low Way and;

                  .       Lowset receivers are located at L8m above ground level, highset receivers at 4.6m

                          above ground level.


           A comparison between the current and future corresponding traffic noise levels at the most

           affected fa ade of dwellings adjoining the roads are presented in Table 13.

                             Rufous Street              57dBA              64dBA              +7dBA

         It can be seen in Table 13 that there will be a traffic noise increase of approximately 1dBA along

         David Low Way and between SdBA to 7dBA along Woodland Drive and Rufous Street. Woodland

         Drive and Rufous Street currently carry low traffic volumes and hence low traffic noise levels. The

         increase of noise levels from SdBA to 7dBA above current levels due to the increase in traffic

         volumes will likely be noticeable at the residences.



         The   possible     noise control treatment is    provision of acoustic upgrades         to   existing residential

         buildings, but it is understood that this option is not feasible. A reduction of noise impacts is

         expected if an alternate access to the shopping centre via David                  Low   Way is provided. It is
