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.

4. Compliance

Pursuant to section 255D of the Sustainable Planning Act 2009, the Department of Transport and Main Roads has been nominated by the Chief Executive of the Department of Infrastructure Local Government and Planning as the entity responsible for the administration and enforcement of concurrence agency conditions within TMR’s area of interest. The developer should obtain a letter from TMR detailing satisfaction of compliance prior to commencement of use.

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


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




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.

EPP Noise contains limits to control Background Creep (the progressive increase in

background noise levels due to new activities in an area). These limits are

summarised in Table 3.3 below. These limits apply to overall emission from the

entire site.

3.3 ENVIRONMENTAL PROTECTION ACT 1994

The object of the Environmental Protection Act (EPA 94) is to protect Queensland‟s

environment while allowing for development that improves the total quality of life,

both now and in the future, in a way that maintains the ecological processes on which

life depends.

The Act nominates a series of Noise Standards, which are summarised in Table 3.4.

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.

adjoining residential lots; noise levels are forecast to comply with the internal LA01

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




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.


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.
