Closest Residential to North

The next closest residential apartments with direct line of sight to the outdoor dining area are to the
north – Block 14, and to the north-north-west, Block 2. Block 14 is approximately 75 metres from the
outdoor dining area and has line of sight to approximately 80% of the outdoor dining area. Block 2 is
approximately 50 metres from the outdoor dining area and has line of sight to approximately 60% of the
outdoor dining area.


Block 14

At a 75 metre separation distance the patron noise levels would be:

         0600 to 0700 hours:          85 dB(A) LWA – 46 (distance) = 39 dB(A) LAeq,adj,T with line of sight, less
                                       7 dB(A) for the residential balcony balustrade = 32 dB(A) LAeq,adj,T.

         0700 to 2200 hours:          95 dB(A) LWA – 46 (distance) = 49 dB(A) LAeq,adj,T with line of sight less
                                       7 dB(A) for the residential balcony balustrade = 42 dB(A) LAeq,adj,T.

         2200 hours to midnight: 92.5 dB(A) LWA – 46 (distance) = 46.5 dB(A) LAeq,adj,T with line of sight,
                                  less 7 dB(A) for the residential balcony balustrade = 40 dB(A) LAeq,adj,T.

For the time varying noise of patrons laughing and talking the noise limits are:

         daytime (0700 to 1800 hours):                    50 dB(A) LAeq,adj,T;
         evening (1800 to 2200 hours):                    45 dB(A) LAeq,adj,T;
         night-time (2200 to 0700 hours):                 40 dB(A) LAeq,adj,T.

The daytime, evening and night-time noise limits are complied with for the above scenarios, for Block
14.


Block 2

At a 50 metre separation distance the patron noise levels would be:

         0600 to 0700 hours:          83 dB(A) LWA – 42 (distance) = 41 dB(A) LAeq,adj,T with line of sight, less
                                       7 dB(A) for the residential balcony balustrade = 34 dB(A) LAeq,adj,T.

         0700 to 2200 hours:          93 dB(A) LWA – 42 (distance) = 51 dB(A) LAeq,adj,T with line of sight less
                                       7 dB(A) for the residential balcony balustrade = 44 dB(A) LAeq,adj,T.

         2200 hours to midnight: 90.5 dB(A) LWA – 42 (distance) = 48.5 dB(A) LAeq,adj,T with line of sight,
                                  less 7 dB(A) for the residential balcony balustrade = 41 dB(A) LAeq,adj,T.

For the time varying noise of patrons laughing and talking the noise limits are:

         daytime (0700 to 1800 hours):                    50 dB(A) LAeq,adj,T;
         evening (1800 to 2200 hours):                    45 dB(A) LAeq,adj,T;
         night-time (2200 to 0700 hours):                 40 dB(A) LAeq,adj,T.

The daytime and evening noise limits are complied with for the above scenarios, as is the early morning
period. However, the night-time period (2200 to midnight) is potentially exceeded by 1 dB(A). Given
that it is unlikely that there would still be 100 patrons in the outdoor dining area between 2200 hours and
midnight on a regular basis, this minor exceedance should be considered acceptable.
