1 INTRODUCTION

1.1 SCOPE OF STUDY

Air Noise Environment was commissioned by RSL Care Pty Ltd to undertake a noise impact
study for a proposed RSL retirement village in Cooroy. The assessment has considered the
impacts of road and rail noise on the retirement village, as well as the acoustic impact of the
development on surrounding sensitive receptors (on-site and off-site).

Modelling of road and rail noise has been completed to determine areas potentially affected
by the Cooroy Connection Road and the Cooroy rail corridor. Where exceedances are
predicted acoustic controls are considered for the development in accordance with the
requirements of the Queensland Department of Main Roads' and the Environmental
Protection (Noise) Policy 1997°.

Noise emissions from the proposed development including services and fixed plant have been
assessed in accordance with the Noosa Shire Planning Scheme (2006)*.

1.2 THE PROPOSED DEVELOPMENT

The development site (Lot 1 on RP 215922) comprises an undeveloped 9.508 Ha lot and is
located at the corner of the Cooroy Connection Road and Pearsons Road in Cooroy (see
Figure 1). The Cooroy rail corridor is located on the western side of the Cooroy Connection
Road, which borders the south-western boundary of the development.

The proposed retirement village will comprise the following features:

120 bed two storey aged care facility;

two apartment blocks each comprising up to 20 units;
118 single storey Independent Living Units (ILUs); and
multi-purpose community village centre including pool.

Figure 2 presents the proposed lot layout for the development. Computational predictive noise
modelling has been undertaken to determine whether mitigation measures are required to
achieve an appropriate acoustic environment at the development.

2 ASSESSMENT CRITERIA
2.1 ROAD TRAFFIC NOISE

The Queensland Department of Main Roads through its Road Traffic Noise Management:
Code of Practice (2000) specifies noise criteria for new and existing roads. Criteria for
proposed residential developments from the Code of Practice specify the requirements for the
current and future noise conditions as follows.

Criteria for residential development (Temporary or Permanent Occupancy) requires that:

Residential (Temporary or Permanent Occupancy)

‘Habitable Floors

" 60 dB(A) L1o (18 Hour) or less, where existing levels measured at the local government
deemed-to—comply dwelling setback distance are greater than 40 dB(A) Leo (8-Hour)
between 10 pm and 6 am; or

« 57 dB(A) Lio (18 hour) or less, where existing levels measured at the local government
deemed-to—comply dwelling setback distance are less than or equal to 40 dB(A) Loo
(8-hour) between 10 pm and 6 am

* Where the above criteria cannot be met, internal maximum design criterion levels
specified in table, AS 2107-1987.

Note: All external levels stated are free-field with the expectation that additional 2.5 dB(A)
increase is applied for the facade correction when the building is constructed. This will
achieve a level of less than 63 dB(A) and 60 dB(A), respectively, 1 metre from the most
exposed facade of a building.’

Specific guidance is also provided by the OMR for outdoor areas at developments:
‘Balconies and formal external open areas

® 60 dB(A) Lio (18 Hour) or less, where existing levels measured at the local government
deemed-to—comply dwelling setback distance are greater than 45 dB(A) Loo (18-Hour);
or

* 57 dB(A) Lio (18 hour) or less, where existing levels measured at the local government
deemea-to—comply dwelling setback distance are less than or equal to 45 dB(A)
Loo (18-hour).’

The above criteria has been considered for the purposes of this noise assessment.

2.2 RAIL NOISE

The Queensland Environmental Protection Policy (Noise) (EPP (Noise)) provides the following
guidance in relation to maximum noise levels appropriate for residential areas affected by rail
noise in Queensland:

“The planning levels for a railway are the following noise levels, assessed 1 m in front of
the most exposed part of an affected noise sensitive place —

a) 65 dB(A), assessed as the 24 hour average equivalent continuous A-weighted sound
pressure level;
b) 87 dB(A), assessed as a single event maximum sound pressure level.”

As the proposed development is located near a proposed rail corridor to be used on a
frequent basis both criteria are considered appropriate for the assessment of rail noise
impacts on the development. It should be noted that, for comparison to free field noise levels,
the above criteria must be adjusted by a correction of 2.5 dB(A). This gives an equivalent free
field criteria of 62.5 dB(A) for the Lcg24-hour and 84.5 for the Lamax.

Where exceedance of the 87 dB(A) criterion is predicted, an appropriate internal noise Lamax
criterion to be considered is 50 dB(A), as adopted by the Brisbane City Council.

2.3 SERVICES AND FIXED PLANT NOISE

2.3.1 Noosa Planning Scheme 2006

According to the Noosa Planning Scheme 2006, the proposed retirement village is located in
a community services zone in the Cooroy and Lake McDonald Locality and is designated as a
Type 3 residential use (multiple housing — retirement and special needs). Division 6
(Residential Code) of the planning scheme provides general guidance for the impacts of a
Type 3 residential on surrounding landuses.

specified by the Queensland Environmental Protection Agency have been applied for the
purposes of the assessment. Section 2.3.2 discusses these criteria in detail.

2.3.2 Queensland Environmental Protection Agency

The Environmental Protection Agency, through amendments to the Environmental Protection
Regulation, places noise nuisance limits on air conditioning equipment and refrigeration plant
as detailed in Table 2.2.

For intermittent noise sources, such as noise from service and delivery vehicles (as shown on
Figure 2), a commonly adopted criteria is an average Laio noise level not exceeding average
background levels by more than 3 dB(A). This criteria is commonly applied by the
Environmental Protection Agency as a licence condition for industrial premises.

3 BASELINE NOISE MONITORING

3.1 SELECTION OF MONITORING POSITION

Two attended noise monitoring positions were chosen for the purposes of the assessment.

The first monitoring position was located at the development site boundary adjacent to the
Cooroy Connection Road. The noise monitoring position has a direct line of sight to the
railway and road, hence was unobstructed from vehicular and train noise emissions. Attended
noise measurements were also completed at this location for determining maximum noise
levels associated with passing trains.

The second monitoring position was located at the rear of the development site, at the end of
Trading Post Road. The purpose of the noise monitoring was to determine to typical
background noise levels experienced by nearby residents which have a potential to be
impacted by the proposed retirement village.

The monitoring locations are depicted on Figure 1 in Appendix A and Plate 1 in Appendix C.

3.2 METHODOLOGY FOR NOISE MONITORING

Noise measurements were made using an Acoustic Research Laboratories environmental
noise logger (ARL215) and Larson Davis sound meter. The serial number and calibration
information for each instrument is presented in Table 3.1. An averaging time of 15 minutes
was adopted and measurements were made over at least a 24-hour period as detailed below.
The microphone was positioned at a height of 1.2 m above ground level and fitted with a
windshield throughout the measurements.

Noise measurements for trains passing by the development site were also completed by Air
Noise Environment during a site visit on 4 July, 2007. Measurements were made using a
Type 2 Svantek 943AE sound level meter (Serial Number 5163) and calibrator (Serial
Number 358).

Details of the NATA certified calibrations of these instruments are presented in Table 3.2.

Half-hourly meteorological data from the meteorological station at Tewantin showed that the
weather conditions were both calm and dry. Hence, all measured noise data is valid for use in
the noise assessment.

The 8-Hour Lago of 33.5 dB(A) indicates that a noise level criteria of 57 GB(A) Lato,1s-nour
(free field) is applicable to the development (refer to Section 2) for assessment of road traffic
noise impacts. For private open space, the 60 dB(A) Lato,1s-nour (free field) criterion is
applicable.

4 ROAD TRAFFIC NOISE ASSESSMENT

41 NOISE PREDICTION METHODOLOGY

The methodology adopted for the assessment is as required by the Queensland Department
of Main Roads (2000) guideline, Road Traffic Noise Management: Code of Practice. As
detailed in this procedure, predictions for a 10 year traffic horizon from the proposed
completion date of the expansion project were undertaken. For the purposes of the
assessment predictions were undertaken in accordance with the methodology described in
the United Kingdom, Department of Transport (1988) procedure, Calculation of Road Traffic
Noise (CoRTN 88).

The noise predictions for the proposed development were completed using the proprietary
software package Cadnaa (Computer Aided Noise Abatement Model), developed by
DataKustik. The noise modelling involved prediction of potential receptor noise levels at the
proposed development utilising the CoRTN method of calculation. The methodology gives
consideration to various elements of the road design including traffic flows, traffic vehicle
composition, road gradient, acoustic shielding by other buildings, and road surface type. The
method predicts Lajo,18 nour Noise levels which are the noise levels exceeded 10 % of the time
between the hours of 6 am and midnight.

The road surface type utilised in the predictions was a 10 mm chip seal (3.0 dB(A) correction)
for the Cooroy Connection Road. A photograph showing the road surface is presented on
Plate 2 in Appendix C.

4.2 POTENTIALLY IMPACTED RECEPTORS

Hypothetical receptor positions with a potential to be impacted by noise from road traffic were
selected from current plans of the proposed development as shown on Figure 2. Receptors
were placed at worst-case locations for the ILU lots and other proposed buildings (village
centre, care facility and two-storey apartments). A total of 101 receptors have been modelled.

4.3 TRAFFIC DATA

The Queensland Department of Main Roads has provided 2006 traffic data for the Cooroy
Connection Road, north of Pearsons Road. The 2005-2006 growth rate for the Cooroy
Connection Road is 5.35 %. This growth rate has been applied to predict 2007 and 2018
AADT counts. Table 4.1 presents a summary of the traffic data used for the assessment.

4.4 MODELLING ASSUMPTIONS

As identified on Figure 2, the retirement village is proposed to have both single-storey and
two-storey residential housing or apartments. Noise level predictions assume a receptor
height of 2.0 m and 5.0 m above the existing ground level for ground floor and first floor
housing respectively.

A noise source height of 0.5m is adopted for vehicles on the Cooroy Connection Road.
Variations in speed (and therefore traffic noise) were determined by the model in accordance
with the corrections described in CoRTN (1988) based on the road gradient and percentage
of heavy vehicles in the fleet being considered.

4.5 NOISE PREDICTIONS

4.5.1 Introduction

Noise predictions were undertaken for 2018 as required by the Queensland Department of
Main Roads. The following sections discuss in detail the results of the noise modelling and
the predicted compliance.

45.2 Model Validation

Comparison of the monitoring results with the predicted receptor noise levels for existing
traffic levels indicates that the modelling is over-predicting by up to 1.8 dB(A), as shown in
Table 4.2 below.

TABLE 4.2: VALIDATION OF CALCULATIONS

 

Receptor 2007 Predicted 2007 Measured Accuracy

 

 

 

 

 

Monitoring 66.3 64.5 +18

 

This prediction is within the 2 dB(A) variation specified in the DMR’s Road Traffic Noise
Management: Code of Practice. Hence the noise model has been considered valid for the
purposes of this acoustic assessment.

4.5.3 Predicted Noise Levels

1. Figure 2 provides a summary of the receptor locations referred to in this table.
2. Levels shown in bold represent exceedences of the appropriate noise criteria (57 dB(A) free field).

According to the results presented in Table 4.3, the DMR noise level criterion is exceeded by
up to 16.6 dB(A) at ILU Receptor 85. Results are summarised as follows:

« atotal of 71 out of 101 receptors exceed DMR criterion;
= non-compliance is predicted at 67 ILU receptors; and

* non-compliance is predicted at the proposed Apartment 2 (ground and first floor) and the
Aged Care Facility (ground and first floor).

Figure 3 presents ground floor open space noise contours for the proposed development. As
can be seen from Figure 3, noise levels at 1.5 m above ground are predicted to exceed the
60 dB(A) noise criterion for a quarter of the site. Limited compliant open space area is
predicted for the row of housing closest to the Cooroy Connection Road. Approximately two-
thirds of the courtyard space at the Aged Care Facility is predicted to comply.

Mitigation options for reducing noise levels are discussed in the following sections.

4.6 MITIGATION OPTIONS

4.6.1 Overview

Given the exceedance in the DMR criteria, appropriate mitigation measures should be
adopted to establish an appropriate acoustic environment for aged care purposes. The
following section discusses the effectiveness of an acoustic barrier and the required
construction materials for achieving internal noise criteria.

4.6.2 Acoustic Barrier

Further noise modelling has been completed to predict the effectiveness of a 2.5 m acoustic
barrier located along the site boundary, fronting the Cooroy Connection Road (see Figure 4).
The acoustic barrier is assumed to be constructed of a material with a mass density of
12 kg/m? with no air gaps.

As identified on Table 4.4, the construction of a 2.5 m acoustic barrier is predicted to reduce
noise levels at the proposed site by up to 9.1 dB(A) (Receptor 17). Compliance is predicted at
41 out of the 101 receptor positions (compared to 30 receptor positions without the acoustic
barrier).

Figures 4 to 8 present predicted noise contours for ground floor open space at ILUs closest to
the Cooroy Connection Road. As identified on these figures, areas of compliance are located
in the shadow zone of the buildings.

Section 4.6.3 discusses potential construction materials for buildings situated in areas which
still exceed the DMR criterion with the barrier in place.

4.6.3 Alternate Construction Materials

The following section discusses the construction material requirements necessary for 2.5 m
acoustic barrier, as described in Section 4.6.2, has been taken into account in determining the
necessary facade treatments.

AS 3671 — 1989 Road Traffic Noise Intrusion — Building Siting and Construction defines the
Traffic Noise Reduction (TNR) as the traffic noise exposure level (Laer) minus the
satisfactory internal noise level (Larec). Typically a 3 dB(A) reduction is applied to Laio noise
levels predicted in the modelling to approximate to Lac. As the external traffic noise
predictions generated estimated free-field noise levels a correction to these levels must first
be made to predict facade noise levels. Typically a +2.5 dB(A) correction is applied to free-
field noise levels to approximate to facade levels.

AS 2107 — 2000 Acoustics - Recommended Design Sound Levels and Reverberation Times
for Buildings Interiors specifies recommended internal noise levels for various building types.
Based on the recommended design sound levels for houses and apartments near major
roads, a 40 dB(A) internal Lacg noise criteria has been used to determine construction
category requirements.

facades requiring Construction Category 3, the required mitigation should be determined
upon further analysis by a qualified noise consultant, in accordance with clause 3.4 of
AS 3671.

Given the required construction category, AS 3671 provides typical STC information for
standard construction types. STC (Sound Transmission Class) is a commonly referenced
descriptor of the effectiveness of a material to reduce the noise energy transmitted through
that material. The TNR must be adjusted to give the STC, and is estimated as equivalent to
TNR + 6 dB(A) to account for the spectral composition of the noise source (as per Table 4.5).

Table 4.6 presents typical STC data for standard construction types that may be suitable for
achieving the required noise reductions identified above (except for the first floor of
Apartment 2). For construction materials associated with the first floor of Apartment 2, refer
to Table 5.4 in Section 5.3.2 of the Rail Noise Assessment.

Before any construction material is chosen for the affected receptors, STC information should
be sought from the suppliers to ensure that the minimum STC’s as detailed in Table 4.5 are
achievable. In order to achieve design STC ratings it is essential that the acoustically treated
areas be constructed in a manner conducive to maximising sound attenuation. For example
there must be no air gaps around windows or at the eaves, which could act as noise
pathways.

As a minimum it is recommended that all building elements (including the roof) are selected to
achieve the minimum STC as defined in Table 4.6.

4.6.5 Open Space

In order to minimise noise levels at open spaces for ILUs it would be necessary to provide
useable areas in the shadow zone of each of the ILU buildings. Additional shielding in the
form of architectural acoustic barriers may also be required to increase the compliant area for
some of the ILU buildings.

As identified on Figure 4, the two courtyard areas at the Aged Care Facility are predicted to
comply with the 60 dB(A) noise criterion. For private open spaces provided at Apartment 2,
compliance is more problematic. For these areas it is likely that specific treatments for the
individual affected balconies would need to be considered. In particular the use of movable
acoustic screens and acoustically absorptive linings for affected balconies is likely to provide
a more appropriate mitigation measure. It is recommended therefore, that the provision of
appropriate acoustic treatments for balconies is considered at the detailed design phase of
the project.

5 RAIL NOISE ASSESSMENT

5.1 NOISE PREDICTION METHODOLOGY

The potential impact of rail noise on the proposed development has been determined using
the baseline noise monitoring data set. Typically, noise contour data is provided by
Queensland Rail (QR) identifying the setback distance required for achieving compliance with
the Lamax 87 dB(A) criteria. Upon discussion with QR, it was determined that there was no
existing noise contour data available for the relevant section of the Cooroy Railway Corridor,
hence the need to rely on the monitoring data for this assessment.

Section 5.2 discusses the monitoring results associated with train noise for the proposed
retirement village site.

5.2 ASSESSMENT OF MONITORING RESULTS

Based on the noise monitoring data presented in Table 3.3 (Section 3.4), the 24-hour
Laeq Criterion of 65 dB(A) is expected to be achieved at the development site.

Table 5.1 presents the Lamax noise levels measured by Air Noise Environment at the site
boundary adjacent to the Cooroy Connection Road (see Figure 1).

TABLE 5.1: MAXIMUM NOISE LEVELS AT THE DEVELOPMENT SITE BOUNDARY
FRONTING THE COOROY CONNECTION ROAD (dB(A))

 

 

 

Source of Data Lamax (Free-Field)
Continuous unattended monitoring 95.0
Attended noise monitoring of train noise 88.8

 

 

 

 

The attended noise measurements at the boundary of the site have determined that the Lamax
noise level of a passing QRail tilt train is 88.8 dB(A). During the unattended noise monitoring,
the highest Lawax noise measurements determined were 94.0 dB(A) and 95.0 dB(A). These
noise levels may potentially be associated with train horns. Hence, an exceedance of up to
10.5 dB(A) relative to the EPP noise criteria is expected for the portion of the site nearest the
rail line.

The noise levels indicated in Table 5.1 were measured at the site boundary, at a distance of
40 m from the passing trains. Based on noise attenuation calculations, compliance with the
87 dB(A) criterion is predicted to be achieved at a setback distance of 75 m from the railway
line. Therefore, 23 ILU buildings and Apartment 2 exceed the train noise criterion. Mitigation
options are presented in the following sections.

5.3 RAIL NOISE MITIGATION

5.3.1 2.5 m Acoustic Barrier

Further noise calculations have been completed to determine the effectiveness of 2.5 m
acoustic barrier, as identified on Figure 4. The 2.5 m acoustic barrier is suitable for providing
attenuation for both road traffic noise (as discussed in Section 4.6) and rail noise.

Table 5.2 identifies the noise levels at various setback distances from the boundary of the
development site using a 2.5 m acoustic barrier.

* Levels shown in bold represent exceedences of the appropriate noise criteria (57 dB(A) free field).

As identified on Table 5.2, noise levels are predicted to comply with the noise criterion for
ground floor levels only. Limited attenuation is predicted for first floors due to their elevation
above the top of the 2.5 m acoustic barrier. First floor noise levels at the Apartment 2 adjacent
to the Cooroy Connection road are predicted to exceed the Lamax Criterion by up to 3.2 dB(A).

5.3.2 Construction Requirements

As discussed in the previous section, exceedance of the 87 dB(A) Lamax criterion is predicted
for the first floor facades of Apartment 2 facing the Cooroy railway line. In order to achieve an
internal Lamax noise criterion of 50 dB(A), appropriate construction materials must be
implemented into the building design.

Table 5.3 provides the attenuation required for potential construction materials. Table 5.4
identifies potential construction materials that could achieve the required attenuation.

It is noted that the rail noise attenuation requirements for Apartment 2 (STC 40.2) is greater
than that predicted for road traffic noise attenuation (STC 37.2 as shown in Table 4.5, Section
4.6.3). Therefore, the higher STC of 40.2 must be achieved.

6 SERVICES AND FIXED PLANT NOISE

6.1 INTRODUCTION

The proposed retirement village will include a range of services and fixed plant, which have a
potential to impact the acoustic environment of the surrounding residential houses. Noise
emissions are expected to come from the following sources:

* waste collection services for all ILUs and care facility buildings;

» delivery of goods including refrigerated food to the care facility building;
« air conditioning units for all ILUs and care facitity buildings; and

* refrigeration condensers for care facility buildings.

These services and fixed plant have the potential to impact on noise amenity at both on-site
receptors (including residents of the {LUs) and off-site receptors. The nearest off-site
sensitive receptors (residential housing) are located to the east of the development, along
Trading Post road and to the north.

The following sections provide an assessment of the potential impacts of each of these
services and fixed plant items.

6.2 ASSESSMENT OF IMPACTS

6.2.1 Fixed Plant

Currently the detailed design of fixed plant items proposed for the retirement village have not
been finalised by the design team. Continuous noise sources at the site are likely to include
air conditioning and/or refrigeration plant for |LU and care facility buildings.

For the ILUs, the air conditioning units adopted for the development would be similar to those
of typical residential developments. Given the small size of the unit(s) likely to be required for
these buildings, impacts on surrounding uses (which predominantly include other ILUs) is
expected to be minimal. To minimise any potential impacts, however, it is recommended that
all condenser units for the ILU air conditioning systems be located as far as practicably
possible from sleeping areas for adjacent ILUs. Furthermore, it is recommended that, where
practical, all condenser units are located adjacent to the wall of the buildings such that there
is no angle of view to the condenser unit from any bedrooms of adjacent ILU buildings.

For the aged care facility and multi-purpose community village building, the design of the fixed
plant noise sources is not known at this stage. Given this the potential impact cannot be
predicted and a design noise limit for the plant must be specified instead. In accordance with
the Environmental Protection Regulation, a criteria based on the higher of the average
Lago noise level of 36.5 dB(A) and 40 dB(A) (refer to Table 2.2) is appropriate.

 

AIR NOISE ENVIRONMENT PTY LTD
PA1750\REPORTING\1750FINAL.DOC Page 24

Page 30

=
RSL Care ==
Proposed RSL Retirement Village, Cooroy — Road and Rail Noise Assessment SS

 

The design limit for any continuous fixed plant at the proposed aged care facility has been
calculated on the basis of the following assumptions:

» a 40 dB(A) noise limit (as specified in the EPP(Noise)), which the total noise level from
all continuous noise sources must not exceed;

* aminimum source to receptor distance of 25 m (for closest ILU); and

+ all plant are located in direct line of sight of the nearest neighbouring property (ie, they
are not shielded by the roofline or other structures or topographic features).

On the basis of these assumptions, the total sound power level from all continuous noise
sources at the site must be a maximum of 76 dB(A) to ensure that the specified night-time
criteria of 40 dB(A) is not exceeded at the nearest receptor position. If all noise sources are
shielded from the nearest receptors a sound power level of 86 dB(A) or more may be
acceptable depending on the height of the sources relative to the acoustic screening and the
type of structure involved.

It is recommended that continuously operating plant are located as far as possible from
proposed potentially sensitive development.

6.2.2 Loading Dock Noise

The proposed site layout has an area designated for service access associated with the aged
care facility, as shown on Figure 2. The regular services associated with the aged care facility
will most likely include refrigerated food trucks and waste disposal services. Based on site
survey plans, the minimum distance to the nearest sensitive receptors is 50 m (one-storey
residential house to the north of the development site).

Given the short-term nature of the above noise sources, the appropriate criterion to use for
assessing the acoustic impact is a background Laio plus 3 dB(A) noise level. Noise monitoring
Position 2 indicates an Laio noise level for the period between 7 am to 6 pm to be 56.1 dB(A).
Hence, a 59.1 dB(A) criterion is adopted. The 56.1 dB(A) noise level was measured during a
weekday, when the majority of service vehicles are expected to make deliveries.

Table 6.1 presents a summary of maximum source noise levels for refrigerated truck
deliveries and waste disposal vehicles measured by Air Noise Environment personnel.
Table 6.2 presents a summary of maximum predicted receptor noise levels for each of the
sources identified in Table 6.1.

7 CONCLUSIONS AND RECOMMENDATIONS

7.1 ROAD TRAFFIC NOISE

The modelling of road traffic noise for a 10 year horizon from construction of the proposed
residential subdivision development has been completed. According to the modelling results,
non-compliance is predicted for a significant proportion of the development site at ground
floor and first floor levels.

Compliance with the noise criteria is likely to be achieved provided the following mitigation
options are implemented:

» €a2.5 metre acoustic barrier is constructed at the boundary of the development site along
the Cooroy Connection Road (see Figure 4). The acoustic barrier should have a mass
density of 12 kg/m? and be continuous with no air gaps;

« buildings are to be constructed of materials providing acoustic attenuation similar to those
identified on Table 4.6. It is important to note that actual construction materials can not be
confirmed until detailed design plans are finalised for the development;

+ air conditioning is provided for all areas of the residential buildings requiring Construction
Category 2 or 3; and

* a detailed acoustic assessment prepared by a qualified acoustic consultant, detailing
building materials, construction methods, and design is required for buildings requiring
Construction Category 3.

In addition to this, it is recommended that private open spaces at units situated nearest to the
Cooroy Connection Road be located on the front side of the buildings (ie, away from the
facade facing the Cooroy Connection Road). Additional shielding in the form of architectural
acoustic barriers to provide additional acoustic shielding to open spaces may also be
required.

For first floor balconies facing the Cooroy Connection, located at Apartment 2, consideration
should be given to the provision of acoustic screens during the detailed design phase of the
project.

7.2 RAIL NOISE

Impacts of noise associated with the Cooroy Railway Corridor have been investigated by the
assessment of unattended and attended noise monitoring data completed at the proposed
development site. Based on the noise monitoring results, it is predicted that train noise levels
passing by the proposed retirement village will exceed the relevant criterion by up to
10.5 dB(A).

Compliance with the noise criteria is likely to be achieved provided the following mitigation
options are implemented:

Proposed RSL Retirement Village, Cooroy — Road and Rail Noise Assessment

 

+ a2.5 metre acoustic barrier is constructed at the boundary of the development site along
the Cooroy Connection Road (as per the recommendations for road traffic noise
mitigation);

. first floor facades at the two-storey Apartment 2 facing the Cooroy Connection Road are
to be constructed of materials providing acoustic attenuation similar to those identified on
Table 5.4. It is important to note that actual construction materials can not be confirmed
until detailed design plans are finalised for the development.

7.3 FIXED PLANT AND SERVICES

The assessment has considered the potential impacts of services and fixed plant including
waste collection, air conditioning and refrigeration units on surrounding sensitive land uses
including both on and off-site receptors. Fixed plant noise and services for the proposed
retirement village are expected to be located at the aged care facility and muiti-purpose
community village building.

The following findings have been determined from the assessment of fixed plant and services
at the retirement village:

* all fixed air conditioning and refrigeration plant installed at the proposed care facility and
community village centre is located as far as practicable from surrounding sensitive land
uses;

» the total sound power level for all fixed air conditioning and refrigeration plant installed
at the proposed care facility should be a maximum of 76 dB(A). An additional 10 dB(A)
or higher may be acceptable if provision of acoustic screens are provided or units are
shielded from the nearest sensitive receptors; and

» delivery services and waste collection are to occur between the hours of 7 am and 6 pm
only.

A response provided by an electronic circuit which modifies
sound in such a way that the resulting level is similar to
that perceived by the human ear.

This is the scale on which sound pressure level is
expressed. It is defined as 20 times the logarithm of the
ratio between the root-mean-square pressure of the sound
field and the reference pressure (0.00002N/m’).

This is a measure of the overall noise level of sound
across the audible spectrum with frequency weighting (i.e.
‘A’ weighting) to compensate for the varying sensitivity of
the human ear to sound at different frequencies.

Refers to a sound pressure level determined at a point
close to an acoustically reflective surface (in addition to the
ground). Typically a distance of 1 metre is used.

Refers to a sound pressure level determined at a point
away from reflective surfaces other than the ground with
no significant contribution due to sound from other
reflective surfaces; generally as measured outside and
away from buildings.

A measure of the frequency of sound. {!t measures the
number of pressure peaks per second passing a point
when a pure tone is present.

This is the equivalent steady sound level in dB(A)
containing the same acoustic energy as the actual
fluctuating sound level over the given period. For a steady
sound with small fluctuations, its value is close to the
average sound pressure level.

This is the dB(A) level exceeded 90% of the time, T.

This is the dB(A) level exceeded 10% of the time, T.

This is the dB(A) level exceeded 50% of the time, T.

The A-weighted sound power level in dB.
