receptors (lots 17, 18, 19, and 21) based on the expected building layouts of the Lots as described below
and indicated in the figures below.

A SoundPLANTM computer model was developed for these noise sources as described activities and used to
predict noise emissions from the compactor and loading docks to the sensitive receptors (lots 17, 18, 19,
and 21). Predictions were made for the following scenarios:

        •    All loading docks and compactor operating concurrently, representing the worst-case scenario
             for day time noise emissions.
        •    All loading docks operating concurrently, representing the worst-case scenario for evening and
             night time noise emissions.
        •    Only the compactor operating;
        •    Mechanical plant operational scenarios as described in this report.

The analysis was conducted based on the following assumptions:

        •    Mechanical plant decks indicated in Figure 2 have a sound power level of 90 dB(A) Leq each.
        •    Kitchen exhaust fan indicated in Figure 2 has a sound power level of 99dB(A) Leq;
        •    Loading dock trucks have a sound power level of 101 dB(A) L max. No idling of trucks was assumed
             within the sites (including the refrigeration trucks) and such restrictions should be included if
             not yet followed (e.g. signs installed at the entry and along the boundaries of the shopping
             centre loading docks.
        •    Compactor indicated in Figure 2 has a sound power level of 100dB(A) Lmax.
        •    Kitchen exhaust fans being turned off between 10pm and 7am and other plant adjacent and
             within loading docks not operational after 10pm and prior to 7am.
        •    Compactor is not operational between 6pm and 7am;
        •    No trolley collection between 10pm and 7am.
        •    The presence of a 6m wide plantation buffer between the northern boundary of the residential
             lots and the shopping centre paved loading dock and entry boundary.
        •    Façade line of proposed residential development approximately 8 metres from loading dock
             boundary (refer to the closest sensitive receiver buildings used in calculations indicated in figure
             below)
