To ensure compliance with the noise limits waste collection vehicles should be limited to accessing the
Facilities Building during the daytime only, from 0700 to 1800 hours.


PATRON NOISE

The dining area will have a capacity of up to 150 diners and is proposed to trade from 0600 hours to
midnight. During the early morning, from 0600 to 0700 hours, it is unlikely that there would be more
than approximately 30 diners present. During the daytime, evening and up to midnight it has been
assumed that there could be up to the maximum capacity, namely 150 diners.

In accordance with Figures 2 and 3 of this report the dining area is to be upgraded with windows and
multi fold walls so that it is possible to enclose the area containing 150 seats, to become an indoor
dining area. The dining area (including the pizza bar) will be licensed for the consumption of alcohol,
and this is controlled by the Office of Liquor and Gaming Regulation (OLGR). It should be noted that as
these areas are licensed noise from patrons and amplified entertainment is under the control of OLGR.

Using the formula for patron noise LWA = 15 × log10(number of patrons) + 64 dB(A), then for the different
time periods the predicted patron noise levels would be:

     •    0600 to 0700 hours:     (15 × 1.48) + 64 = 86 dB(A) LWA for 30 diners and 82 dB(A) for 15
                                  diners;
     •    0700 hours to midnight: (15 × 2.18) + 64 = 97 dB(A) LWA for 150 diners and 92 dB(A) LWA for 75
                                  diners.


Closest Residential to East

The closest residential apartments with direct line of sight to the dining area are Blocks 18 to 21
inclusive. The floor level of these Blocks is elevated at least 12 metres above the dining area, with
Blocks 19 and 20 the closest, at a separation distance of approximately 50 metres. At this elevation,
and given that all of the dining area (for the 150 seated diners) is roofed, there would be line of sight to
approximately 50% of the dining area and the remaining 50% would be obscured from view by the roof.
Therefore, for approximately 50% of the dining area the roof acts as an acoustic barrier between the
diners and the residential apartment Blocks 18 to 21 inclusive.

At this separation distance (and allowing 50% protection to the dining area by the roof) the above patron
noise levels would be:

     •    0600 to 0700 hours:           82 dB(A) LWA – 42 (distance) – 5 (solid balustrade) = 35 dB(A) LAeq,adj,T
                                        with line of sight; and
                                        82 dB(A) LWA – 42 (distance) – 8 (roof over and solid balustrade) = 32
                                        dB(A) LAeq,adj,T.
                                        Combined noise level for 30 diners = 37 dB(A) LAeq,adj,T.

     •    0700 to 1800 hours:           92 dB(A) LWA – 42 (distance) – 5 (solid balustrade) = 45 dB(A) LAeq,adj,T
                                        with line of sight; and
                                        92 dB(A) LWA – 42 (distance) – 8 (roof over and solid balustrade) = 42
                                        dB(A) LAeq,adj,T.
                                        Combined noise level for 150 diners = 47 dB(A) LAeq,adj,T.

     •    1800 to 2200 hours:           97 dB(A) LWA – 42 (distance) – 25 (noise reduction for enclosed dining
                                        area) = 30 dB(A) LAeq,adj,T for 150 diners.

     •    2200 hours to midnight: 97 dB(A) LWA – 42 (distance) – 25 (noise reduction for enclosed dining
                                  area) = 30 dB(A) LAeq,adj,T for 150 diners.
