2.10.3

The attended noise monitoring confirmed that background noise levels are low, as would be
expected in a predominantly rural type environment. Traffic noise from the Bruce Highway was

audible at all positions, but was not a significant influence at Position 1.

Potential Impacts

Impact of External Noise Sources

The principal external noise sources likely to impact on the proposed use include road traffic
noise associated with the Bruce Highway. The large number of vehicle trips per day using this
route significantly impacts on the noise environment. The use of Holt Road as an access road is

unlikely to pose a significant constraint in terms of potential noise impacts.

Impact of Development on External Noise Sensitive Receivers

As the specific uses likely to be established are not known for all of the proposed lots at this
stage, some guidance as to suitable locations on the site for typical business and industrial
activities has been provided. The more likely noise sources for development occurring on the site
are anticipated to include:

> Air conditioning plant;

> Loading dock noise, such as forklift, truck movements and heavy goods vehicles; and

> Vehicle movements associated with the overall development and access roads.

The assessment included typical values associated with, for example, moderately sized air
conditioning system, average forklift noise etc. The total sound pressure levels for these noise
sources (at 1m) are as follows:

>» Air conditions plant: 97.3 dB(A);

> Fork lift truck: 98.8 dB(A); and

> Articulated truck: 97.3 dB(A).

Noise predictions for these non-ERA activities were also completed for the site using modelling
software. The modelling assumed flat topography and a minimum separation distance of 280m
from the existing residential dwellings to the nearest proposed industrial allotment, with three

potential receptors. Results have been included within Tables 5.2a, 5.2b and 5.2c of the Air
