Environmental Noise Level Impact Assessment for Proposed Expansion of Existing Backpacker
Accommodation at 102 Pacific Avenue to Include 106 Pacific Avenue, Sunshine Beach                       Page 13 of 24




CONCLUSIONS

The existing backpacker accommodation located at 102 Pacific Avenue, Sunshine Beach, for which
David Moore & Associates Pty Ltd prepared the original noise report for in 2009, is proposed to be
extended onto 106 Pacific Avenue. The existing dwelling is to remain on site and undergo some
minor alterations to be suitable for the proposed backpacker accommodation. In accordance with
advice from Nadine Gorton, Town Planner, Noosa Council have requested a noise impact assessment
be prepared for this proposed expansion of the backpacker accommodation.

Adjoining the existing and proposed backpacker accommodation to the north-east is residntial, whilst
to the north-west is a veterinary surgery. To the south-east is also residential, which adjoins the
existing backpacker accommodation.

This report has been prepared in response to the Council information request, with noise limit criteria
based on the Environmental Protection (Noise) Policy 2008 and the adopted background sound levels
based on the results of the 2009 ambient noise assessments, together with a further 7-day ambient
noise assessment in September 2018. The predominant noise source in this area is traffic on Pacific
Avenue, which is a direct link between the David Low Way and Noosa Heads and carries a significant
volume of traffic, together with the natural sounds of birds, wind in the vegetation, domestic activities,
etc. The September 2018 background sound levels were specifically assessed adjacent to the closest
adjoining residences, which are to the immediate north-east of the subject site.

Pacific Avenue is not a transport noise corridor and as the existing residence is not being replaced or
extended traffic noise impact does not require consideration.

Potential noise impacts from the proposed extension to the backpacker accommodation onto 106
Pacific Avenue could include vehicle activities (cars driving, car doors closing and car engines
starting), people laughing and talking and plant and equipment (airconditioning units). The 2018
background sound levels were used to determine the noise limits in accordance with the ‘background
creep’ criteria (as these were lower than the 2009 background sound levels), for the closest adjoining
residence to the north-east. Source noise levels were based on previous assessments conducted by
the consultant of similar premises.

With the acoustic barrier nominated in Figure 4 in place the noise of on-site vehicle activities, people
laughing and talking and airconditioning units complies with the noise limit criteria (background Creep)
for the complete 24-hour day.

To further ensure compliance with the noise limits for 24-hours per day, once the location and exact
number of airconditioning units has been determined, and the manufacturer and model number (and
associated noise levels) selected, this information should be provided to the acoustic consultant to re-
assess the noise impact from the airconditioning units and, if any of the noise limits are exceeded,
nominate suitable noise control measures.


RECOMMENDATION

It is recommended that, from an environmental noise perspective, the proposed expansion of the
backpacker accommodation from 102 onto 106 Pacific Avenue should be approved, provided the
noise control measures detailed in this report are incorporated into this development.
