Attachment 3—Further advice
General advice
1. Stormwater Infrastructure Works Condition 4 requires the construction of stormwater infrastructure within the Nathan Street road reserve. Under Section 50(2) and Schedule 6 of the Transport Infrastructure Act 1994 (TIA) and Part 5 and Schedule 1 of the Transport Infrastructure (State-Controlled Roads) Regulation 2006, you must have written approval to carry out ancillary works and encroachments on a state-controlled road. These development conditions do not constitute such an approval. You will need to contact the Department of Transport and Main Roads on [email protected] to make an application for a Road Corridor Permit under section 50(2) of the TIA to carry out ancillary works and encroachments. Ancillary works and encroachments include but are not limited to advertising signs or other advertising devices, paths or bikeways, buildings/shelters, vegetation clearing, landscaping and planting.
2. Road Access Works ApprovalCondition 5 (Vehicular Access) requires crossover construction. Under sections 33 of the Transport Infrastructure Act 1994, written approval is required from the Department of Transport and Main Roads to carry out road (including installation of signage and access works) on a state-controlled road. Please contact the Department of Transport and Main Roads via [email protected] to make an application for road works approval. This approval must be obtained prior to commencing any works on the state-controlled road reserve. The approval process may require the approval of engineering designs of the proposed works, certified by a Registered Professional Engineer of Queensland (RPEQ). Please contact Transport and Main Roads as soon as possible to ensure that gaining approval does not delay construction.
3. Road Access Approval
Under sections 62 of the Transport Infrastructure Act 1994, written approval is required from the Department of Transport and Main Roads before legal access associated with the proposed use can occur.
Please contact the Department of Transport and Main Roads via [email protected] to make an application for permitted access approval. This approval must be obtained prior access to the state-controlled road reserve for the use occurs.

EXECUTIVE SUMMARY
This report details a noise impact assessment report undertaken for a proposed
material change of use (service station & food and drink outlet) at 206-201 Nathan St
Aitkenvale QLD 4814 (Lot 28, 29 & 30 on RP716469).
Noise emission from the development has been assessed against:
Townsville City Plan 2014.
Environmental Protection (Noise) Policy 2008.
Environmental Protection Act 1994.
Noise emission from typical use of the proposed development has been forecast to
nearby residential dwellings and potential 5 storey multi-unit developments on
adjoining land parcels. The assessment incorporates a 5m acoustic barrier along the
north, east and south boundaries (i.e. equal to the top of highest windows on the
second storey of houses).
Conclusions and Recommendations
It is concluded that -
The noise environment at the subject site and surrounds is dominated by
emission from Nathan Street during day and evening periods. Night time
periods are substantially quieter but are still punctuated with sporadic car and
truck pass-bys.
Noise emission criteria have been nominated for the development based on
the control of background creep and the acoustic quality objectives within the
Environmental Protection (Noise) Policy 2008, as well as the noise standards
440U and 440V for air-conditioning and refrigeration plant within the
Environmental Protection Act 1994.
Detailed mechanical plant information is not yet available for the entire site.
However a noise emission forecast has been carried out based on plant
selections for a similar project. Noise emission forecasts from general
operation of the site have been based on peak hour usage rates applied for a
similar project.
Mechanical plant associated with the development will require substantial
acoustic treatment to achieve noise emission goals at existing receptors and
potential 5 storey residential development on adjoining residential lots. This
is likely to require these units to be housed in a plant room or full enclosure,
with acoustic treatment to all air intakes and discharge points.
5
Noise emission from general activity at the development can be controlled to
existing sensitive receptors, with open windows, when a 5m acoustic barrier
is located along the development site boundaries that adjoin residential lots.
New multi-storey development on adjoining residential lots is forecast to
achieve noise intrusion criteria at the ground floor and second storey due to
screening provided by the 5m acoustic barrier. Dwellings located on the third
storey and above are expected to be built to a minimum of QDC MP 4.4
Category 1, due to noise exposure from Nathan Street which is a gazetted
transport noise corridor. Category 1 treatment requires a 25 dB reduction
across the building façade, which will adequately control forecast noise
emission from the proposed development.
It is expected that development will be serviced by a prime mover with semi-
trailer for fuel deliveries, a service vehicle for food and stock deliveries, and
an overhead loading garbage truck for refuse collection. The frequency of
visits is not known at this stage. However it is assumed that fuel deliveries
will occur no more than once a week; and that there may be multiple service
vehicle deliveries daily and a refuse collection every couple of days. It is
expected that these impacts can be adequately controlled by limiting service
vehicle access to day time periods only.
We recommend that -
We recommend that continuously operating plant is selected, located, and
attenuated to meet the criteria detailed in Table 3.3 and Table 3.4. It is
expected that plant will be located on the roof, and that substantial acoustic
treatment will be required to meet noise emission goals; due to the small
setback, height of the residential receptor overlooking the potential plant
deck, and the low noise criteria during night time periods. We recommend
that a detailed design of noise emission is carried out before selection and
installation of plant.
A 5.0m high acoustic barrier is constructed along the northern, eastern, and
southern boundaries as nominated by Council and described in Section 4.4.
The access of service vehicles on-site is restricted to day time hours only and
limiting the duration of noise producing activities (e.g. idling) as much as
practicable.
A 15 km/hr speed limit is adopted for the site.
6
The concrete for vehicle movement areas and fuelling points not comprise of
polished or smooth sealed surfaces due to the propensity for wheel squeaks
and chirps. Loose grates, covers or panels should also be avoided.

1. INTRODUCTION
This report details a noise impact assessment report undertaken for a proposed
material change of use (service station & food and drink outlet) at 206-201 Nathan St
Aitkenvale QLD 4814 (Lot 28, 29 & 30 on RP716469).
The proposed development consists of a single storey building housing the service
station and fast food outlet shopfronts, covered refuelling area, drive through lane,
parking areas, as well as a water/air service point. A 5m acoustic barrier has been
incorporated along the north, east and south boundaries at the request of Council in
order to be equal to the top of the highest windows on the second storey of houses.
The purpose of this report is to:
Recommend appropriate noise emission criteria for the development.
Present the results of the existing noise survey.
Forecast noise emissions from the development and assess against the
nominated criteria for existing sensitive receptors and potential sensitive
receptors, up to 5 storeys, on adjoining residential lots.
Recommend acoustic treatments to achieve noise emission criteria, as
required.
The site plan is shown in Figure 1.1 with further plans shown in Appendix A. These
plans do not yet show the 5m acoustic barrier along the north, east and south
boundaries as required by Council. Figure 1.2 shows the subject site in relation to
Nathan Street and nearby sensitive receivers. Figure 1.3 shows the subject site as
seen from Nathan Street.

2. EXISTING NOISE ENVIRONMENT
An on-site survey was conducted between 29th August and 4th September, 2017.
The measurement location (ML1) was positioned at a height of 1.5m above ground
level, as shown in Figure 2.1. The measured levels are considered free field. This
location was chosen as it was considered to be representative of noise levels
experienced at the existing dwellings, while being as far removed from Nathan Street
as possible.
Figure 2.1: Aerial photograph showing measurement location ML1 (Google Earth)
All instrumentation used in this assessment holds a current calibration certificate from
a certified NATA calibration laboratory. The following instruments were used to
measure the ambient noise levels-
Noise Sentry environmental noise logger
Rion NC-73 calibrator
Ambient sound pressure levels were measured generally in accordance with
Australian Standard AS1055.1:1997 - „Acoustics-Description and measurement of
environmental noise - Part 1: General procedures‟. Ambient noise levels were
recorded at continuous 125ms periods and post-processed into 15 minute
increments. Photographs of ML1 are shown in Figure 2.2.
A summary of overall measurement results is shown in Table 2.1, with rated
background levels shown in Table 2.2.

1. Background level based on R1 Category AS1055.3
Measured data was noted to approach the noise floor of the instrumentation during
the night time which will influence the measured LA90 noise levels.
Average background noise levels for night time periods have been drawn from AS
1055.3-1997 Acoustics – Description and measurement of environmental noise –
Part 3: Acquisition of data pertinent to land use (AS 1055.3); which provides
13
estimated average background levels for different areas containing residences in
Australia, as shown in Table 2.2. An LA90,(10pm-7am) background level of 30 dB(A) has
been used in the assessment to reflect an R1 Category. We consider this to be
suitable due to the sporadic traffic flows observed along Ross River Road during
night time periods.

During the day time the attended periods the noise environment at the development
site was controlled by emission from Nathan Street with no other audible noise
sources. During evening and night time periods the noise environment was
controlled by sporadic traffic along Nathan Street and insect noise.
Attended measurements taken at site note:
Levels of 50-55 dB(A) from free flowing traffic and 60-62 dB(A) from truck
pass-bys, measured at the rear of the site.
Levels of 55-60 dB(A) from free flowing traffic and 70 -72 dB(A) from truck
pass-bys, measured at approximately 15m setback from the Nathan Street
kerb (i.e. similar setback to closest receptors to Nathan Street R1 and R5 as
shown in Figure 4.1.
As such the noise environment at the development site and surrounds can be
reasonably considered to be is controlled by emission from Nathan Street during
periods of heavy usage (i.e. day and evening periods). During periods of light usage
14
the environment is controlled by occasional vehicle pass-bys and lulls of distant
traffic and natural sounds.

3. NOISE CRITERIA
3.1 TOWNSVILLE CITY PLAN 2014
The development is sited within a Medium Density Residential Zone and is subject to
the Medium Density Residential Zone Code (6.2.1). Noise related performance
outcomes and acceptable outcomes for this code are shown in Table 3.1.
Table 3.1: Noise related performance outcomes and acceptable outcomes for the TCC Neighbourhood Centre Zone Code
Performance Outcomes Acceptable Outcomes
PO12
Development minimises impacts on surrounding land and provides for an appropriate level of amenity within the centre, having regard to:
a) Noise
AO13
No acceptable outcome is nominated.
Any development on the subject site will have an impact on surrounding land uses by
introducing buildings which will provide screening of noise emission from Nathan
Street (the dominant noise source in the area) and by the introduction of mechanical
plant and activity on site.
Noise impacts to neighbouring land uses are considered to be effectively minimised
by compliance with the Environmental Protection (Noise) Policy 2008 (EPP Noise), in
line with the Noise and Vibration Assessment Guidelines (SC6.4.3.15).
16
3.2 ENVIRONMENTAL PROTECTION (NOISE) POLICY
The Environmental Protection (Noise) Policy (EPP Noise) nominates Environmental
Values for residential dwellings (qualities of the acoustic environment conducive to
protecting the amenity of the community) and prescribes Acoustic Quality Objectives
for protecting or enhancing these Environmental Values. These Acoustic Quality
Objectives and Environmental Values are shown in Table 3.2.

4. NOISE IMPACT ASSESSMENT
Noise emission from the development has been forecast using the proprietary
software PEN3D developed by Noise Mapping Australia. PEN3D utilises the General
Prediction Model (GPM) described by Bies and Hansen. The basic equation adopted
by the GPM is:
Lp = Lw – 20Log10R – 10Log104π + AE
Where
Lp is the sound pressure level at an observer
Lw is sound power level of the source
20Log10R – 10Log104π is the distance attenuation (spherical propagation)
AE is the excess attenuation factors (barriers, air absorption)
4.1 POTENTIAL IMPACTS
The proposed development consists of:
A service station with proposed operating hours of 24 hours a day, 7 days a
week; during day, evening and night time periods.
A food and drink outlet with proposed operating hours of 7:00 am to 10:00
pm, 7 days a week; during day and evening periods.
Operation of the development is expected to introduce the following noise emissions:
Mechanical plant providing compressed air, ventilation, air-conditioning and
refrigeration to the development.
Fuel bowsers.
Patron noise (including vehicle movements, door slams, and conversation).
Use of the drive through ordering system (vehicle movements, speaker box
and patron noise emission).
Service vehicles bringing fuel and stocks to the development, as well as
rubbish removal.

4.2 EXISTING SENSITIVE RECEPTORS
Sensitive receptors close to the development site are shown graphically in Figure 4.1
and described in Table 4.1. Ground floor receptors have been modelled at 1.8m
above natural ground level, while second storey receptors have been modelled at
4.6m above natural ground level.

4.3 POTENTIAL MULTIPLE STOREY DEVELOPMENT RECEPTORS
Noise impacts on potential multiple storey developments on adjoining lots have been
considered in the assessment at the request of Council. Receptors have been
assumed to be setback 1m from subject site boundary with the ground floor receptor
height at 1.8m above natural ground level with a floor-to-floor height of 2.8m as
shown in Table 4.2. Receptors locations are shown graphically in Figure 4.2.

We note that the development site and surrounds are located within a Transport
Noise Corridor as shown in Figure 4.3. Applicable noise levels for transport noise
corridors are shown in Table 4.3. New residential development built within a
transport noise corridor will require acoustic treatment to mitigate traffic noise
intrusion as shown in Table 4.3.

4.4 BARRIER TREATMENT
Council have advised that they require a barrier equal to the highest window of the
second level of houses. On this basis a 5m high acoustic barrier has been
incorporated along the north, east and south boundaries of the development site; in
order to be equal to the top of the highest windows on the second storey of houses,
as required by Council. This barrier will be required to be free of gaps and be
constructed with:
A material that has a minimum surface mass of 15 kg/m2, OR
A material that has a sound reduction index (RW)/sound transmission class
(STC) of 28.
Council have advised that wood is an unacceptable material with which to build the
acoustic barrier. Alternate barrier materials should be selected that achieve the
requirements above.
Modelled barrier extents are shown graphically in Figure 4.4.

4.5 CONTINUOUS NOISE SOURCES
Detailed mechanical plant information is not yet available for development. A noise
emission forecast has been carried out based on mechanical plant selected for a
similar project. Sound power data used in the assessment is shown in Table 4.5.
This data is indicative only and an acoustic assessment should be carried out based
on the ACTUAL plant selections once these are available, in order to accurately
determine noise control requirements.

Vehicle movements have been modelled as a moving point source which follows the
main routes for vehicles within the development, and is weighted for the number of
anticipated movements within a representative time frame (e.g. 1 hour) during day,
evening and night time periods. The assessment is based on the concrete surface
having a low noise finish, such as brushed concrete or asphalt. Polished or smooth
sealed surfaces should be avoided due to propensity for wheel squeaks and chirps.
Loose grates, covers or panels should also be avoided, and have not been
addressed in this assessment.
The assessment has been based on the anticipated peak hour usage rates shown in
Table 4.7, which were provided for a similar development.
Table 4.7: Anticipated use of the development
Use Traffic Generation (vehicles per hour)
Peak day Peak evening Peak Night
Fast food outlet 25 25 0
Service station 43 43 30
Idling vehicles have been used to represent noise emission at bowsers and at drive
through order and collection points. Each vehicle using these points has been
assumed to idle at these locations for 1 minute.
27
Noise emission from patrons (car door close, engine start, conversation) has been
modelled as fixed point sources at representative locations. The dining area of the
restaurant is likely to be enclosed, not orientated towards the closest receptors, and
is expected to adequately contain patron noise. The assessment assumes that
during night time periods cars and patrons will only use areas near the bowsers and
parking spaces close to the service station area.
It is assumed that all traffic generated by the fast food outlet travels through the drive
thru. Noise emission from the speaker box has been modelled as a fixed point and is
assumed to emit noise for approximately 30 seconds for each vehicle using the drive
thru within a representative time frame (e.g. 1 hour). The assumed location of the
speaker box is shown in Figure 4.6.
Figure 4.6: Assumed speaker box location

4.7 SERVICE VEHICLES
It is expected that development will be serviced by a prime mover with semi-trailer for
fuel deliveries, a service vehicle for food and stock deliveries, and an overhead
loading garbage truck for refuse collection. The frequency of visits is not known at
this stage. However it is assumed that fuel deliveries will occur no more than once a
week; and that there may be multiple service vehicle deliveries daily and a refuse
collection every couple of days. It is expected that these impacts can be adequately
controlled by limiting service vehicle access to day time periods only.

Approximately 14 dB of noise reduction is required to achieve compliance with noise
emission criteria when a 5m acoustic barrier is present along the site boundary. This
is expected to require full enclosure of mechanical equipment along with acoustically
treated openings to air intake and discharge points. Acoustic review of mechanical
plant selections, locations and treatments should be carried out as the mechanical
design is developed.

With the provision of a 5m acoustic barrier along the development site boundaries

Acoustic Quality Objectives, assuming a 25 dB reduction across the building façade
which is required for dwellings constructed under QDC MP 4.4 Category 1.

5. DISCUSSION
The noise environment around the subject site is controlled by vehicle pass-bys
along Nathan Street. This results in reasonably quasi-steady noise level during
periods of heavy traffic flow, and fluctuating levels during lighter flow periods.
A significant barrier has been recommended along the northern, eastern and
southern boundaries to help control noise impacts to the nearest neighbours
The noise forecasts are based on the parameters detailed in Section 4 and provide a
reasonable sample of typical activity on the site. Variations to these conditions (such
as larger vehicles, anti-social behaviour, loud music or warning signals) may lead to
short term exceedance of the criteria.
Sporadic short term noise events are expected at the site, such as fuel and stock
deliveries as well as refuse collection, which may cause some disturbance. These
events should be limited to day time periods, and scheduled with consideration for
the effects on neighbours.

6. RECOMMENDATIONS AND CONCLUSION
This report details a noise impact assessment report undertaken for a proposed
material change of use (service station & food and drink outlet) at 206-201 Nathan St
Aitkenvale QLD 4814 (Lot 28, 29 & 30 on RP716469).
The proposed development consists of a single storey building housing the service
station and fast food outlet shopfronts, covered refuelling area, drive through lane,
parking areas, as well as a water/air service point.
Noise emission from the development has been assessed against:
Townsville City Plan 2014.
Environmental Protection (Noise) Policy 2008.
Environmental Protection Act 1994.
Noise emission from typical use of the proposed development has been forecast to
nearby residential dwellings and potential 5 storey multi-unit developments on
adjoining land parcels. The assessment incorporates a 5m acoustic barrier along the
north, east and south boundaries (i.e. equal to the top of highest windows on the
second storey of houses).
Conclusions and Recommendations
It is concluded that -
The noise environment at the subject site and surrounds is dominated by
emission from Nathan Street during day and evening periods. Night time
periods are substantially quieter but are still punctuated with sporadic car and
truck pass-bys.
Noise emission criteria have been nominated for the development based on
the control of background creep and the acoustic quality objectives.
Detailed mechanical plant information is not yet available for the entire site.
However a noise emission forecast has been carried out based on plant
selections for a similar project.
It is expected that development will be serviced by a prime mover with semi-
trailer for fuel deliveries, a service vehicle for food and stock deliveries, and
an overhead loading garbage truck for refuse collection. The frequency of
visits is not known at this stage. However it is assumed that fuel deliveries
will occur no more than once a week; and that there may be multiple service
vehicle deliveries daily and a refuse collection every couple of days. It is
40
expected that these impacts can be adequately controlled by limiting service
vehicle access to day time periods only.
Mechanical plant associated with the development will require substantial
acoustic treatment to achieve noise emission goals at existing receptors and
potential 5 storey residential development on adjoining residential lots. This
is likely to require these units to be housed in a plant room or full enclosure,
with acoustic treatment to all air intakes and discharge points.
Noise emission from general activity at the development can be controlled to
existing sensitive receptors, with open windows, when a 5m acoustic barrier
is located along the development site boundaries that adjoin residential lots.
New multi-storey development on adjoining residential lots is forecast to
achieve noise intrusion criteria at the ground floor and second storey due to
screening provided by the 5m acoustic barrier. Dwellings located on the third
storey and above are expected to be built to a minimum of QDC MP 4.4
Category 1, due to noise exposure from Nathan Street which is a gazetted
transport noise corridor. Category 1 treatment requires a 25 dB reduction
across the building façade, which will adequately control forecast noise
emission from the proposed development
We recommend that -
We recommend that continuously operating plant is selected, located, and
attenuated to meet the criteria detailed in Table 3.3 and Table 3.4. It is
expected that plant will be located on the roof, and that substantial acoustic
treatment will be required to meet noise emission goals; due to the small
setback, height of the residential receptor overlooking the potential plant
deck, and the low noise criteria during night time periods. We recommend
that a detailed design of noise emission is carried out before selection and
installation of plant.
A 5.0m high acoustic barrier is constructed along the northern, eastern, and
southern boundaries as nominated by Council and described in Section 4.4.
The access of service vehicles on-site is restricted to day time hours only and
limiting the duration of noise producing activities (e.g. idling) as much as
practicable.
A 15 km/hr speed limit is adopted for the site.
41
The concrete for vehicle movement areas and fuelling points not comprise of
polished or smooth sealed surfaces due to the propensity for wheel squeaks
and chirps. Loose grates, covers or panels should also be avoided.

APPENDIX C – GLOSSARY OF ACOUSTIC TERMS
The following is a brief description of the technical terms used to describe traffic noise to
assist in understanding the technical issues presented in this document.
Event maximum sound pressure level (LA%,adj,T), L01 The L01 level is calculated as the noise level equalled and exceeded for 1% of the measurement time, for example 9 seconds in any 15 minute interval. L01 is an appropriate level to characterise single events, such as from impulsive or distinctive pass-by noise. In this Report, the measured L01 levels for day/evening/night are not averaged but are arranged from low to high in the relevant day/evening/night interval and the value that is found at the 90th percentile (L10 of L01 sample) in the interval is recorded as its “L01” level. The level can be adjusted for tonality or impulsiveness.
Average maximum sound pressure level (LA%,adj, T), L10 The “L10” level is an indicator of “steady-state” noise or intrusive noise conditions from traffic, music and other relatively non-impulsive noise sources. The L10 level is calculated as the noise level equalled and exceeded for 10% the measurement time, for example 90 seconds in any 15 minute interval. The measured L10 time-intervals for day/evening/night are arithmetically averaged to present the “average maximum” levels of the environment for day/evening/night. The level can be adjusted for tonality or impulsiveness.
Background sound pressure level (LA90,T), L90 Commonly called the "L90" or "background" level and is an indicator of the quietest times of day, evening or night. The L90 level is calculated as the noise level equalled and exceeded for 90% the measurement time. The measured L90 time-intervals are arithmetically averaged to present the “average background” levels of the environment for day/evening/night. The level is recorded in the absence of any noise under investigation. The level is not adjusted for tonality or impulsiveness.
Equivalent Continuous or time average sound pressure level (LAeq,T), Leq Commonly called the "Leq" level it is the logarithmic average noise level from all sources far and near. The maximum 1-hour levels within the day/evening/night time intervals are referenced for building design. The level can be adjusted for tonality.
Façade-adjusted level A sound level that is measured at a distance of 1.0 metre from a wall or facade. The level is nominally 2.5 dB higher than the free-field level.
Free-field level A sound level that is measured at a distance of more than 3.5 metres from a wall or facade.
