Environmental Noise Level Impact Assessment for Proposed Wave Lagoon, 500/90 Beach Road,
Noosa North Shore                                                                                      Page 1 of 16




INTRODUCTION

It is proposed to establish a private wave lagoon at 500/90 Beach Road, Noosa North Shore (Lot 500
on SP 215779), in the south-east corner of this property. Potential noise sources associates with this
wave lagoon, which will be approximately 0.4 Ha in area, are the blowers used to generate the waves
and people noise. There will also be pumps used in association with the wave lagoon, for the purpose
of water transfer and water filtration/treatment.

The noise of the blowers and pumps is steady state whilst the noise of people is time varying.

To determine the existing acoustic environment a 7-day ambient noise assessment was conducted
from the subject site, from adjacent to one of the closest adjoining residences. Typical source noise
data for the pumps and people is already held by the consultant, whilst wave lagoon blower noise was
obtained from an acoustic report prepared for a similar scale wave lagoon at Palm Springs, California.

With respect to noise limits the now superseded version of the Environmental Protection (Noise)
Policy 2008 contained details of ‘background creep’ and allocated actual noise limits for both steady
state and time varying noise sources. From previous work conducted by the consultant in the Noosa
Council area this is the noise limit criteria which was applied. However, whilst background creep is
still detailed in the current Environmental Protection (Noise) Policy 2019, no actual noise limits are
defined.

Currently the only noise criteria defined by the environmental protection legislation are the default
noise standards of the Environmental Protection Act 1994 and the Acoustic Quality Objectives of the
Environmental Protection (Noise) Policy 2019.

In preparing this report the site plan prepared by Tim Ditchfield Architects, project 1732, drawing CD
1.01 dated June 2019 was referenced.

Refer Figure 1 for locality plan and noise monitoring location and Figure 2 for proposed site plan.
