Executive Summary In September 2015 the NSW Government announced a package of works to renew the Sydney Stadium network, which would include Western Sydney Stadium, a new 30,000 seat stadium (the Project) on the site of the existing stadium in Parramatta (the Site).

The Site is located at 11-13 O’Connell Street Parramatta and is situated within the broader context of Parramatta Park, approximately one kilometre north-west of Parramatta Station and the Parramatta CBD.

The Site comprises the existing stadium and stadium complex, surface car parking facilities (to the north and west of the stadium), Parramatta Swimming Centre to the east of the stadium (located on Crown Land), and a training field to the south of the stadium. The Site is legally described as Lots 951, 952, 953, 954, 955, 956, 957, 958, 959, 961, 962, 963 in Deposited Plan (DP) 42643 and Crown Land Lot 80-3000 (part).

Assessment and development consent for the Project will be undertaken in two stages under Section 83B of the Environmental Planning and Assessment Act 1979 (EP&A Act).

The development application which this Noise and Vibration Assessment supports is only seeking approval for the Proposal (i.e. Stage 1). Specifically, the Proposal includes:

- Concept Proposal for the Western Sydney Stadium, including parking and access facilities, ancillary infrastructure and landscaping; and,

- Staged demolition and removal of the existing stadium and associated infrastructure, including the existing stadium and the associated hardstand areas where required (footpaths, roads, car parks etc.) as well as the Parramatta Swimming Centre.

This report addresses the Secretary’s Environmental Assessment Requirements (SEARs) relevant to the potential noise and vibration impacts of the Proposal.

Criteria

All potentially affected receivers by noise associated with the Project were classified into four Noise Catchment Areas (NCAs). Ambient noise monitoring was undertaken at four locations within each NCA in May 2016. This included both unattended long-term monitoring and short-term attended measurements. These are presented in Section 3.2. Based on the results of these measurements, demolition and operational noise were established for the Proposal and are presented in Sections 4.1 and 4.2.

Operational noise criteria for events at the proposed stadium were derived from the NSW Industrial Noise Policy (EPA 2000), the Noise Guide for Local Government (EPA 2013) and the existing Parramatta Stadium Noise Management Plan (PCCD Consultancy and Design 2008). Noise levels were assessed to two operational noise criteria, one Leq(15min) criteria and one Lmax criteria for all periods of the day, as well as sleep disturbance criteria for the night-time period.

Vibration criteria was established for vibration intensive demolition activities.

Noise Modelling

Demolition and operation noise emission levels for the Proposal were modelled using SoundPLAN 7.3 software, implementing the general prediction method algorithm.

Noise modelling elements as part of the assessment included:

- ground topography

- ground absorption and reflection

- buildings (residential and non-residential)

- noise sources (demolition and operational)



ii

Demolition

Three demolition scenarios were modelled to represent major works to take place during demolition early works; site establishment, site access works/Site finishing and demolition. Demolition activities are anticipated to take place during standard construction hours.

Demolition noise impacts were predicted to exceed project Noise Management Levels at one residence by up to 5 dB, and five non-residential receivers during demolition, which was predicted to be the phase where noise impacts were highest.

The risk of adverse vibration impacts as a result of vibration intensive activities such as concrete breaking or jackhammering were considered to be low due to:

- the distances from the demolition works area to receivers, and

- set back distances were provided to minimise potential impacts on human comfort or structural damage to nearby buildings.

Operation

Operational noise from the Project was modelled based on draft concept proposal drawings. Stadium walls were modelled as full height (refer to EIS Appendix B for Concept Proposal).

Three operational scenarios were modelled to represent the three loudest events that may take place at the proposed stadium; a rock concert, a classical concert and a large sporting event. Noise measurements previously conducted by AECOM were used to derive crowd and music sound power levels which were used in the operational noise model. Events were assumed to take place during the day, evening and night between the hours of 2:00 pm and 12:00 am.

Sporting events are scheduled to take place up to 42 times per calendar year under the Project. Noise impacts from a major sporting event at proposed stadium are predicted to reach 64 dB(A) at the worst affected receivers, approximately equal to current crowd noise levels from the existing Parramatta Stadium. These levels are based on a worst case scenario where crowds are cheering for a 15 minute period, and measured noise levels from the proposed stadium are likely to be lower than those predicted.

The loudest events to take place at the proposed stadium, rock concerts, are predicted to reach levels of 73 dB(A), predicted to be 7 dB higher than impacts from current monitored crowd noise from the existing Parramatta Stadium. Sporting events are predicted to be within 2 dB of noise levels from the existing Parramatta Stadium.

Recommended noise goals for large events are presented in Table 16. It is recommended that assessment to these noise goals serve as a screening test for receivers affected by event noise. Compliance with these recommended goals indicates no significant undue disturbance to the community, in consideration of the infrequency and nature of noise emissions. No further noise treatment is therefore recommended should receivers comply with these noise goals.

Approximately up to 90 receivers are predicted to exceed day and evening noise goals during a sporting event (2pm to 10pm), and up to 190 receivers during the night (after 10pm). 75% of these exceedances are predicted to be less than 5dB above noise goals. Approximately 200 receivers are predicted to exceed daytime and evening noise goals during the loudest likely music concert scenario, a rock concert, and up to 400 exceedances are predicted at night (after 10pm). Approximately half of these exceedances are less than 5 dB.

Additional Road Traffic

The largest increase in traffic volumes due to the stadium operation is predicted to be on O’Connell Street (1% increase). Due to the small number of additional vehicles the increase in noise as a result of traffic generated by the Proposal would be inconsequential (less than 1 dB(A)) on O’Connell Street and Victoria Road, therefore no acoustic treatment is considered necessary.

Recommendations

The development and implementation of a construction noise and vibration management plan is recommended, with recommended noise management measures provided in Section 6.1.



iii

Similarly, an operational noise management plan is recommended for all events taking place at the proposed stadium. Section 6.2 outlines recommended measures to be included by the noise management plan, classified into:

- preventative management

- reactive management

- review mechanism

The implementation of this plan will reduce noise emissions where possible, while managing community expectations. A table of likely benefits from each mitigation measure is presented in Table 29.

Further, it is recommended that the detailed design for the stadium consider architectural acoustic treatments where possible to minimise noise impacts during operation.

1.0 Introduction

1.1 Background In September 2015, the NSW Government announced a package of works to renew the Sydney Stadium network over the next decade, with the Western Sydney Stadium Project forming a key part of this package. Infrastructure NSW (INSW), on behalf of Venues NSW, is therefore seeking approval for the development of a 30,000 seat stadium (Western Sydney Stadium) on the site of the existing stadium (Parramatta Stadium) in Parramatta (the Site). Assessment and approval for the Project will be undertaken in two stages under Section 83B of the Environmental Planning and Assessment Act 1979 (EP&A Act):

1. initial application for the Concept Proposal and demolition works to accommodate the Western Sydney Stadium (Stage 1); and,

2. a second separate application for the detailed design and subsequent construction and operation of the Western Sydney Stadium (Stage 2).

This Noise and Vibration Impact Assessment accompanies the EIS which supports the development application for the Proposal (i.e. Stage 1) only. Specifically, the Proposal includes:


- Staged demolition and removal of the existing stadium and associated infrastructure, including the existing stadium and the associated hardstand areas where required (footpaths, roads, car parks etc.), and the Parramatta Swimming Centre.

Works associated with the removal of below ground infrastructure, excavation works, and construction of the Western Sydney Stadium will be assessed under Stage 2 of the Project once a detailed design has been prepared.

1.2 Purpose of this technical working paper The Secretary’s environmental assessment requirements (SEARs) for the Proposal were issued on 18 April 2016.

2.0 Description of the Proposal

2.1 Site location The Site is located at 11-13 O’Connell Street Parramatta, approximately 25 kilometres west of Sydney Central Business District (CBD). The Site is situated within the broader context of Parramatta Park, approximately one kilometre north west of Parramatta Station and the Parramatta central business district (CBD). The Site is shown in detail in Figure 1, and comprises the existing stadium and stadium complex, surface car parking facilities (to the north and west of the stadium), Parramatta Swimming Centre to the east of the stadium (located on Crown Land), and a training field to the south of the stadium. The Site is legally described as Lots 951, 952, 953, 954, 955, 956, 957, 958, 959, 961, 962, 963 in Deposited Plan (DP) 42643 and Crown Land Lot 80-3000 (part).

The demolition works area comprises the parts of the Site where the demolition works and supporting activities will take place. This area excludes two predominantly vegetated areas to the north and west, and part of the training field to the south. No activities or impacts are proposed in these excluded areas.

A key feature of the local area is Parramatta River, which is located to the west and south of the Site and eventually flows into Sydney Harbour approximately 20 kilometres south east of the Site. Parramatta Park extends across Parramatta River to the west of the Site and includes the world heritage listed Old Government House, approximately 200 metres south west of the Site boundary.

Other land uses surrounding the Site include the Parramatta Park Trust car park to the south east on Parramatta Park land, the old Kings Oval to the south west and the Parramatta Leagues Club and associated surface car park immediately adjacent to the north.

Land use to the east of the Site across O’Connell Street is predominantly comprised of low density residential development, as well as mixed use and public recreation. Notable uses include schools and places of worship (our Lady of Mercy College and St Patricks Cathedral), and the Old Kings School site.

2.2 The Proposal The Proposal comprises Stage 1 of development for the Project. Specifically, the Proposal includes:


- Staged demolition and removal of the existing stadium and associated infrastructure, including the existing stadium and the associated hardstand areas where required (footpaths, roads, car parks etc.), and the Parramatta Swimming Centre.

Works associated with the removal of below ground infrastructure, excavation works, and construction of the Western Sydney Stadium will be assessed under Stage 2, once a detailed design has been finalised.

2.2.1 Western Sydney Stadium Concept Proposal

The Western Sydney Stadium Concept Proposal is shown in Figure 2. The concept proposal provides for:

- a maximum total Gross Floor Area (GFA) of approximately 60,000 m2 (excluding the playing pitch) for the stadium development;

- a maximum total GFA of approximately 20,000 m2 for ancillary uses within the northern corner of the Site;

- transport access and parking facilities;

- public domain elements; and

- landscaping elements throughout the Site.

Stadium features

The concept proposal would provide the following facilities:

- additional seating for approximately 10,000 more spectators in a seating bowl with 30,000 seats, including 27,000 general admission seats and 3,000 corporate seats;

- playing pitch;

- five levels of premium box/terrace, function/lounge offerings and a number of suite offerings;

- flood lighting, stadium video screens and other ancillary fittings; and

- additional facilities for team, media, administration and amenity, including:

police facility and security office;

players changing rooms;

ticket gates and ticket boxes;

media interview rooms;

green room;

production suite and joint operation control room;

event briefing rooms;

hirers office and patron services offices;

first aid facilities;

loading docks for deliveries; and

food, beverage and retail facilities.

Facilities for premium offerings, players, media and broadcasting, administration and deliveries/waste would be located on the western side of the stadium to maximise integration of servicing logistics and internal infrastructure

.

Future development area

The future development area is located along the northern edge of the site with a prominent presence to O’Connell Street, and is earmarked for a building(s) to contain ancillary and complementary uses to the sporting venue/precinct. It is anticipated this building could provide opportunities for Venues NSW through a range of possible uses such as community uses, function or entertainment uses, and/or other permissible uses.

Parking and access

The Concept Proposal would provide limited parking of approximately 500 car parking bays to the north and west of the stadium. The car park would be restricted to corporate and VIP use on game days.

Vehicular access to the stadium complex on non-event days would be provided via a two way vehicular access road from O’Connell Street with entry points both at the north and south of the stadium. It would circle the western side of the stadium to return to O’Connell Street. It is anticipated team buses, service vehicles and loading trucks would access the stadium from the southern entry point to the loading dock south of the stadium. A VIP drop-off point would be provided to the west of the new stadium. It is anticipated that on event days, the northern entry of the access road would be closed or restricted to avoid and minimise conflict and congestion with pedestrians accessing the Site.

2.2.2 Future operation of Western Sydney Stadium

Workforce

Both the proposed workforce and number of patrons at the new stadium complex would vary between event and non-event days.

On event days, the in-house stadium co-ordinator would be responsible for overseeing all events held at the new stadium. Up to 1,000 staff (comprising permanent and contract staff) may be required to operate the stadium to provide catering, security, cleaning and customer service functions. This includes around 600 during sports events, and around 900 during major concert events. Security, police and first aid officers would be located throughout the stadium on event days.

Patronage would also vary depending on the type of event held, with a stadium capacity of 30,000 seats for sporting events.

On non-event days, staffing requirements may vary between some five and 100 employees depending on the level of preparation required for upcoming events and ongoing maintenance requirements.

Hours of operation

The Noise Management Plan for the stadium (PCCD Consultancy and Design, 2008) currently limits events other than sporting events held at the stadium to:

- Music festivals and culture festivals, between 10 am to 8 pm;

- Music concerts on Fridays and Saturdays, or Sundays adjacent to a Monday Public Holiday (except Easter Sunday), between 7 pm to 10 pm;

- Carnivals, between 10 am to 6 pm; and

- Motocross, only on Saturdays until 9.30 pm, and not during Easter or Christmas public holidays.

The hours of operation would be consistent with the existing NRL and A-League game times (generally between 2 pm and 10 pm). However, recognising that the new stadium may attract additional games, music and other entertainment events, the hours of operation may alter in order to respond to the types of events held. An appropriate event noise management plan would be developed for changes to the frequency, type and duration of events.

Event schedule

Once operational (projected early 2019), the Western Sydney Stadium would primarily be used for major sporting events, concerts and fairs.

The stadium is expected to operate as a competition site for teams such as the Parramatta Eels (NRL), the Western Sydney Wanderers (A-League soccer) and other NRL franchises under the NSW Stadia Strategy objectives for the consolidation of venues. The number of event days are therefore projected to increase



12

substantially under the Project (refer to Table 2). An increase in patron attendance to the events is also projected, based on ten year historical growth periods of each sport.

The installation of five tiers of corporate boxes/terraces, function areas and suites would also provide a greater corporate premium offering than the current stadium.

Table 2 provides an indication of future events, however, the exact schedule of future events to be held at Western Sydney Stadium would be developed by Venues NSW in consultation with relevant event organisers and sporting associations. Table 2 Event calendar and attendees

2.2.3 Demolition works

Demolition activities

Demolition would involve the removal of all the existing stands, buildings, surrounds and infrastructure within the boundary of the demolition works area of the Site. A project office compound would be established within the Site to enable appropriate management of demolition activities and deliveries.

The demolition works would be carried out by specialist subcontractors and would involve the following activities:

- site establishment to enable the commencement of demolition activities including the erection of perimeter barrier fencing for site security;

- decommissioning and demolition of the existing stadium, demolition of Parramatta Swimming Centre, related structures and hard and soft landscaping treatments, including all hard stand areas and access paths;

- waste management activities including the removal of classified waste; and

- ‘make safe’ activities including returning all areas to ground level.

These activities would be staged, with the stadium complex being removed first in late 2016 to early 2017, followed by the Parramatta Swimming Centre. All demolition works would be completed by mid-2017.

The proposed staging of demolition works would facilitate the continued operation of the Parramatta Swimming Centre for as long as practical to allow summer events to be completed prior to the demolition. Timing for closure of the pool prior to demolition would be determined by City of Parramatta Council. As such, the demolition works would commence on the western stand and progress to the eastern stand area.



13

Site establishment

To enable commencement of demolition activities on the Site, the existing facilities would be closed down on a given date and perimeter hoardings, fences and signage erected to establish a secure site for demolition. Fencing would also be provided around the exclusion areas to ensure no unauthorised use of the land. Pedestrian and vehicular movements will be maintained around the Site to minimise community impact. A project office compound would then be established within the Site to support construction activities and deliveries.

Demolition activities

Demolition activities would initially involve the removal of classified material identified in a Hazardous Materials Buildings Survey prior to fitout removal and structural demolition works commencing. These materials would be disposed in accordance with relevant requirements and certification would be obtained from a qualified Occupational Hygienist obtained. Upon completion of hazardous material removal, demolition works would progress in a manner to maximise material recycling.

Demolition of the existing stadium would involve:

- Removal of the internal fitout including plasterboard walls, ceilings, services and joinery;

- Demolition of the roof structure by long reach excavators from the ground level;

- Demolition of concrete structural components of the existing spectator stands, buildings and inground footings (to ground level); and

- Removal of the existing stadium light towers.

Demolition of the Parramatta Swimming Centre would involve:

- demolition of slide facilities;

- flattening and stabilising the existing fill mound, potentially moving it northward away from the future access road (to ensure access is available for Stage 2);

- demolition of inground pool structures; and

- removal of trees where required.

All demolition works would be conducted in a safe manner as certified by a qualified structural engineer and carried out in accordance with approved safe work method documents.

Site retention and security

The demolition works would be temporary in nature and appropriately managed. No stockpiles or other ancillary facilities would remain on Site. The Site would be reinstated to a condition with ongoing environmental management controls to minimise offsite impacts prior to the next stage of work commencing (Stage 2 of the Project). These measures may include hydroseeding exposed areas, water management controls, and retention of barrier fencing.

Plant and equipment

Plant and equipment to be used for demolition works would be determined by the demolition contractor. However, the demolition works are anticipated to include the following plant/equipment:

- 250-400 tonne crane and boom lifts;

- 30 tonne long reach excavators;

- 40 tonne excavators;

- bob-cats;

- jackhammers;

- water tanks;

- re-fuelling tanks;

- loading trucks; and

- other small scale / manual equipment .



14

Traffic management

The existing Victoria Road and O’Connell Street intersection would function as the main access gate for the duration of the demolition works, allowing for the safe use of the existing road and traffic light controls without effecting movement of pedestrians, cyclists or road users. A manned vehicle access gate would be established at this main access point to prevent unauthorised access. Traffic movements would be associated with the majority of demolition activities, including dismantling of the stadium light towers, demolishing and removing large structures from the stands by mobile cranes and excavators would be wholly contained within the fenced area.

Material would be transported offsite along the following truck routes:

- east along Victoria St before heading north/south/onward to the waste depot; and/or

- south along O’Connell St before heading west/south/onward to the waste depot.

Use of the above routes would avoid the need for heavy vehicles to travel north along O’Connell Street.

Hours and duration

Standard construction working hours would apply for the duration of the demolition works. The hours for demolition would therefore be confined to:

- 7:00 am to 6:00 pm Monday to Friday

- 8:00 am to 1:00 pm on Saturdays

- No work on Sundays or public holidays.

Whilst not anticipated, some night work may be required and would be considered where it may reduce impacts to the public and local community. Work outside standard hours may also occur to complete tasks safely or more efficiently.

If work is required outside standard construction hours, it would be carried out according to the Interim Construction Noise Guideline (DECC 2009). This would include notifying the local community in advance of any work planned to be carried out outside of standard hours.

Workforce

The contractor for the demolition works would determine the size of the workforce, however it is estimated that a maximum of 45 construction and site management personnel would be on site at any one time.

Program and schedule

Demolition works will commence from late 2016 to early 2017 and take around four to six months. Particular focus would be placed on minimising impact to the operation of the Parramatta Swimming Centre over the 2016-2017 summer months. However, this would be confirmed with City of Parramatta Council. The demolition works for the existing stadium, swimming centre and ancillary infrastructure are planned to be completed by mid-2017.

3.0 Existing Acoustic Environment

3.1 Noise sensitive receivers Figure 3 shows the receivers where noise and vibration impacts were assessed within this report. Residential and other sensitive receivers which could potentially be affected by the Proposal are located across the study area. Unattended and attended noise monitoring was completed to quantify and qualify the existing noise environment in the vicinity of the works (refer to Section 3.2).

Figure 3 Site and receiver locations



16

Four noise catchment areas (NCA) were identified as representing the residential receivers. The noise environment at each of the sensitive receivers within a noise catchment area is considered to be similar (refer to Section 3.2). One logger was placed within each NCA at a representative location. A description of the receivers within each NCA is described in Table 3. Table 3 Noise catchment area descriptions

NCA Description

1 Mixed receivers – Mixture of schools, child care, healthcare facilities, commercial and residential receivers

2 Health care receivers – a number of healthcare facilities including aged care, psychiatric services and community centres

3 Residential receivers – Mixture of single storey and multi-storey residential premises Aged care facility in neighbouring block and the Westmead Hospital Precinct directly to the north west. Cluster of commercial receivers in the north west, near the hospital precinct

4 Residential receivers – Mixture of single storey and multi-storey residential premises

3.2 Noise catchment areas Receivers potentially affected by the noise and vibration associated with the Proposal have been classified into four noise catchment areas according to their noise environments.

Receivers within NCA 1 are generally residential and commercial. A number of schools are also located within the catchment area. The existing acoustic environment is considered as urban and is dominated by traffic noise from O’Connell Street, Victoria Road and Church Street. The distance between the demolition works and the nearest sensitive receivers within the catchment area are approximately 120 metres to 600 metres away.

Similarly to NCA 1, the noise environment in NCA 2 is dominated by road traffic, with sources identified as O’Connell Street, Church Street and local roads. Receivers within NCA 2 are classified as suburban, and comprise primarily single and double storey residential houses, however a number of hospitals and medical facilities are located north of the Site, including Cumberland Hospital. The nearest receivers are located approximately 170 metres to 500 metres from demolition works.

NCA 3 comprises both medium density apartments and single and double storey semi-detached houses, with Westmead Hospital and The Children’s Hospital at Westmead located north-east of the residences. The nearest residences to the Site are set back by approximately 480 metres, separated by Parramatta River and Parramatta Park. Receivers are classified as suburban, with the noise environment characterised by intermittent local road traffic and rail traffic along the main western railway line.

NCA 4 is characterised by relatively low levels of local traffic noise and rail traffic along the main western railway line. Receivers are primarily residential comprising both medium density apartments and single and double storey semi-detached houses. Receivers are classified as suburban. The nearest residential receivers are located around 800 metres south-west of the Site, separated by Parramatta River, Parramatta Park and the main western railway line.

3.3 Existing noise measurements Ambient noise monitoring was undertaken at four locations throughout the study area in May 2016. This included both unattended long term monitoring and short-term attended measurements.

3.3.1 Instrumentation

The noise loggers used for long term monitoring and their locations are presented in Table 4. The sound level meter used to conduct attended surveys was a Bruel & Kjaer 2250 (Serial Number 3000860).

All the acoustic instrumentation employed during the noise measurements comply with the requirements of “AS IEC 61672.1-2004 Electroacoustics – Sound level meters – Specifications” and was calibrated prior to and after the monitoring session with a drift in calibration not exceeding ± 0.5 dB.

All instruments used were within their current National Association of Testing Authorities, Australia (NATA) certified in-calibration period (i.e. calibration in the last 2 years).

3.3.2 Unattended noise measurements

Noise monitoring was conducted to determine existing background noise levels at sensitive receivers. Noise loggers were placed at the locations indicated in Table 4. Noise loggers 1-3 monitored noise levels continuously from 20 May to 30 May 2016 and logger 4 monitored noise levels continuously from 23 May to 30 May 2016.

The loggers measured the noise levels over the sample period and then determined LA10, LA90, LAmax, and LAeq levels of the noise environment. The LA10 and LA90 noise levels are the levels exceeded for 10 percent and 90 percent of the measurement period respectively. The LA90 is taken as the background level. The LAmax is indicative of the maximum noise levels due to individual noise events such as the pass-by of a heavy vehicle. The LAeq level is the equivalent continuous sound level and has the same sound energy over the sample period as the actual noise environment with fluctuating sound levels.

The LA90 noise levels were analysed to determine a single assessment background level (ABL) for each day, evening and night period in accordance with the NSW EPA’s NSW Industrial Noise Policy (INP) (EPA 2000), for each monitoring location. The ABL is established by determining the lowest ten-percentile level of the LA90 noise data acquired over each period of interest. Appendix B presents individual ABLs for each day’s assessment periods.

Events are not scheduled to operate outside the hours of 2:00 pm and 12:00 am, however demolition works will occur during standard construction hours (7:00 am – 6:00 pm) and other operational activities, such as loading dock activities or mechanical plant noise, may occur throughout the day, evening or night period. Two Rating Background Levels (RBLs) have therefore been established, one during event hours (2:00 pm – 12:00 am) and one over 24 hours (12:00 am – 12:00 am).

The background noise level or rating background level (RBL) representing the day, evening and night-time assessment periods is based on the median of individual ABLs determined over the entire monitoring period. Table 5 presents RBLs for event hours and Table 6 for demolition works and other operational activities.

Appendix B also presents the existing LAeq ambient noise level selected for each day, evening and night-time period, in accordance with the INP. An overall representative LAeq noise level is determined by logarithmically averaging each assessment period for the defined monitoring periods.

In accordance with the INP, any noise monitoring conducted during periods of extraneous weather conditions was excluded from the data set. The INP advises that data may be affected where adverse weather, such as wind speeds higher than 5 m/s or rain, occurs. During the measurement period for this assessment, periods of adverse weather occurred during three daytime periods. This was confirmed by using weather data from the Bureau of Meteorology’s (BOM) Sydney Olympic Park weather station.

A full set of monitored results along with graphical noise logging results are presented in Appendix B and periods where data has been omitted are indicated.

3.3.3 Attended noise monitoring

Attended monitoring was conducted at the four unattended monitoring locations on 20 May 2016. Each measurement was conducted over a 15 minute period. Skies were generally clear with scattered clouds and conditions were calm with a slight breeze on the day of monitoring. Table 7 Attended noise monitoring results

4.0 Assessment Methodology

4.1 Construction (demolition) noise and vibration This section specifies the acoustic criteria applicable to the Proposal to control the emission of environmental noise during the demolition works. These criteria have been derived from:

- Interim Construction Noise Guideline

- Assessing vibration: a technical guideline

- DIN Standard 4150: Part 3 1999 - Structural Vibration in Buildings – Effects on Structures; and

- British Standard 7385: Part 2 1993 - Evaluation and Measurement of Vibration in Buildings

This section presents the detailed criteria based on the above documents.

4.1.1 Demolition noise

4.1.1.1 Noise management levels

The risk of adverse impact of demolition noise on a community is determined by the extent of its emergence above the existing background noise level, the duration of the event and the characteristics of the noise.

The ICNG is a NSW Government document that sets out ways to deal with the impacts of construction, including demolition, noise on residences and other sensitive land uses. It presents assessment approaches tailored to the scale of the construction project and identifies practices to minimise noise impacts. The ICNG recommends that a quantitative assessment is carried out for all major construction proposals that are typically subject to the environmental impact assessment processes. A quantitative assessment, based on the likely demolition scenarios, has been carried out for the Proposal. Predicted noise levels at nearby noise sensitive receivers (e.g. residences, schools, hospitals, places of worship, passive and active recreation areas) are compared to the levels provided in the ICNG.

Where an exceedance of the management levels is predicted the ICNG advises that receivers can be considered ‘noise affected’ and the proponent should apply all feasible and reasonable work practices to minimise the noise impact. The proponent should also inform all potentially impacted residents of the nature of the works to be carried out, the expected noise level and duration, as well as contact details.

Where construction noise levels reach 75 dB(A) residential receivers can be considered as ‘highly noise affected’ and the proponent should, in consultation with the community, consider restricting hours to provide respite periods.

The ICNG defines what is considered to be feasible and reasonable as follows:

- Feasible

A work practice or abatement measure is feasible if it is capable of being put into practice or of being engineered and is practical to build given project constraints such as safety and maintenance requirements.

- Reasonable

Selecting reasonable measures from those that are feasible involves making a judgment to determine whether the overall noise benefits outweigh the overall adverse social, economic and environmental effects, including the cost of the measure.”

Work that is proposed outside of standard working hours, as defined in the ICNG, generally requires strong justification. The construction noise management levels (NMLs) for the residential and other sensitive land uses are detailed in Table 8 and Table 9.



21

Table 8 Interim Construction Noise Guideline residential noise management levels

Time of day NML, LAeq,15min, dB(A)1 How to apply

Recommended standard hours: Monday to Friday 7 am to 6 pm Saturday 8 am to 1 pm No work on Sundays or public holidays

Noise affected RBL + 10 dB

The noise affected level represents the point above which there may be some community reaction to noise. - Where the predicted or measured LAeq (15 min) is greater

than the noise affected level, the proponent should apply all feasible and reasonable work practices to meet the noise affected level.

- The proponent should also inform all potentially impacted residents of the nature of works to be carried out, the expected noise levels and duration, as well as contact details.

Highly noise affected 75 dB(A)

The highly noise affected level represents the point above which there may be strong community reaction to noise. - Where noise is above this level, the relevant authority

(consent, determining or regulatory) may require respite periods by restricting the hours that the very noisy activities can occur, taking into account: 1. times identified by the community when they

are less sensitive to noise (such as before and after school for works near schools, or mid-morning or mid-afternoon for works near residences

2. If the community is prepared to accept a longer period of construction in exchange for restrictions on construction times.

Outside recommended standard hours

Noise affected RBL + 5 dB

- A strong justification would typically be required for works outside the recommended standard hours.

- The proponent should apply all feasible and reasonable work practices to meet the noise affected level.

- Where all feasible and reasonable practices have been applied and noise is more than 5 dB(A) above the noise affected level, the proponent should negotiate with the community.

- For guidance on negotiating agreements see section 7.2.2 of the ICNG.

Notes:

1. Noise management levels apply at the property boundary that is most exposed to construction noise, and at a height of

1.5 m above ground level. If the property boundary is more than 30 m from the residence, the location for measuring or

predicting noise levels is at the most noise-affected point within 30 m of the residence. Noise levels may be higher at

upper floors of the noise affected residence.

1. These management levels are based upon a 10 dB reduction through an open window.

4.1.1.2 Construction traffic noise criteria

Noise from construction traffic on public roads is not covered by the ICNG, However it does refer to the Environmental Criteria for Road Traffic Noise (ECRTN) (EPA 1999), now superseded by the NSW Road Noise Policy (RNP) (DECCW, 2011), for the assessment of noise arising from construction traffic on public roads.

In assessing feasible and reasonable mitigation measures under the RNP, an increase of up to 2 dB(A) represents a minor impact that is considered barely perceptible to the average person.



23

Therefore, the noise goal applied to traffic movements on public roads generated during the demolition works is an increase in existing road traffic noise levels of no more than 2 dB(A).

The RNP does not require assessment of noise impact to commercial or industrial receivers.

O’Connell Street and Victoria Road will provide the main access roads to the Site. These roads would be classified as sub-arterial. The external noise criteria are applied 1 m from the external facade of the affected building.

4.1.2 Construction (demolition) vibration

4.1.2.1 Construction structural damage vibration criteria

The EPA’s Assessing vibration: A Technical Guideline (AVTG) (DEC, 2006) has been designed to be used in evaluating and assessing the effects on amenity of vibration emissions from industry, transportation and machinery. The guideline is used in the assessment of vibration impacts caused by the construction and operation of new developments.

Vibration criteria are set primarily according to whether the particular activities of interest are continuous in nature or intermittent, whether they occur during the daytime or night-time and the type of receiver to be assessed, e.g. industrial, commercial or residential.

The effects of vibration in buildings can be divided into three main categories:

- Those in which the occupants or users of the building are inconvenienced or possibly disturbed, i.e. human disturbance or discomfort;

- Those in which the integrity of the building or the structure itself may be prejudiced; and

- Those where the building contents may be affected.

Therefore, vibration levels at sensitive receiver locations must be controlled so as to prevent discomfort and regenerated noise, and in some extreme cases, structural damage.

The AVGT provides criteria for human comfort only. Criteria to avoid structural damage are detailed in DIN 4150 are summarised below.

The German Standard DIN 4150-Part 3 ‘Structural vibration in buildings – Effects on Structures’ provides recommended maximum levels for short-term vibration (Table 11). The standard states that experience has shown that if these values are not exceeded, damage that reduces the serviceability of the structure will not occur.

4.1.2.2 Human comfort vibration criteria

The assessment of intermittent vibration outlined in the AVTG is based on Vibration Dose Values (VDVs). The VDV accumulates the vibration energy received over the daytime and night-time periods.

Maximum and preferred VDVs for intermittent vibration arising from construction activities are listed in Table 12. The VDV criteria are based on the likelihood that a person would be annoyed by the level of vibration over the entire assessment period. Table 12 Preferred and maximum vibration dose values for intermittent vibration (m/s1.75)

4.2 Operational noise criteria This section specifies the acoustic criteria applicable to the Proposal to control the emission of environmental noise due to the operation of the Concept Proposal.

The requirements applicable to the development have been established and derived from:

- NSW Industrial Noise Policy; and

- The Noise Guide for Local Government;

This section presents the detailed criteria based on the above documents.

4.2.1 Operational noise (excluding event noise)

The INP sets out guidelines for the assessment and control of industrial noise. These guidelines are appropriate for the assessment of noise emissions from mechanical plant, car park use and loading dock activities associated with the Proposal. These activities may take place throughout a 24 hour period. The assessment approach detailed in the INP is considered generally appropriate for the control of environmental noise emissions and its implementation has been discussed further in the following sections.



25

The assessment procedure for noise sources has two components:

- Controlling intrusive noise impacts in the short term for residences; and

- Maintaining noise level amenity for particular land uses including residences.

4.2.1.1 Intrusive noise impacts

The INP states that the noise from any single source should not intrude greatly above the prevailing background noise level. Industrial noise sources are generally considered to be acceptable if the equivalent continuous (energy-averaged) A-weighted level of noise from the source (LAeq), measured over a 15 minute period, does not exceed the background noise level measured in the absence of the source by more than 5 dB(A). This is often termed the Intrusiveness Criterion.

The ‘rating background level’ (RBL) is the background noise level to be used for assessment purposes and is determined by the methods given in the INP. Using the rating background noise level approach results in the intrusiveness criterion being met for 90% of the time. Adjustments are to be applied to the level of noise produced by the source that is received at the assessment point where the noise source contains annoying characteristics such as tonality or impulsiveness.

4.2.1.2 Protecting noise amenity

To limit continuing increases in noise levels, the maximum ambient noise level within an area from industrial noise sources should not normally exceed the acceptable noise levels specified in the INP. That is, the background noise level should not exceed the level appropriate for the particular locality and land use. This is often termed the Background Creep or Amenity Criterion. The main purpose of these criteria is to limit continuing increases in noise levels.

For receivers in urban and suburban area, the recommended amenity criteria are shown in Table 13. Recommended amenity criteria for commercial and industrial receivers are also presented. Table 13 Recommended LAeq amenity noise levels

Industrial When in use 70 75 Notes:

1. The INP presents internal criteria for these receivers, a 10 dB reduction has been assumed between external and internal noise levels based upon a window being open for adequate natural ventilation.

- Day is defined as 7:00 am to 6:00 pm Monday to Saturday and 8:00 am to 6:00 pm Sundays and Public Holidays.

- Evening is defined as 6:00 pm to 10:00 pm Monday to Sunday and Public Holidays.

- Night is defined as 10:00 pm to 7:00 am Monday to Saturday and 10:00 pm to 8:00 am Sundays and Public Holidays.



26

When the existing noise level from industrial noise sources is close to the “Acceptable Noise Level” (ANL) given above, noise from the new source must be controlled to preserve the amenity of the area in line with the requirements of the INP.

Observations on and around the Site indicate that noise at all receiver locations is generally dominated by transportation, urban hum and other sources which would not be classified as industrial. Therefore, no corrections to the amenity criteria are warranted.

4.2.1.3 Total environmental noise emission criteria

A summary of the measurements, and intrusive and amenity criteria is given in Table 14. The amenity criteria apply to environmental noise emissions from sources such as building services plant as these sources will run continuously and therefore will have the potential to contribute to background noise creep. Environmental noise emissions from car park and loading dock activities will not be continuous and therefore it is considered more appropriate to assess these sources using intrusive criteria only. Criteria applicable to entertainment and patron activities are discussed later in this report (refer to Section 4.2.3).

The amenity criteria apply over the entire daytime, evening or night-time period, whereas intrusive criteria apply over any 15 minute period. Since noise emissions from mechanical plant, car park use and loading dock activities may occur outside of event hours, RBLs from Table 6 from a 24 hour period have been used. All criteria must be applied at the most affected boundaries. Table 14 Summary of environmental noise emission criteria for residential receivers

2. Evening NMLs have been set to no higher than daytime NMLs based on community’s higher sensitivity to noise during

evening periods.

3. Intrusiveness criterion for evening/ has been set to no greater than daytime criterion in line with the community’s expectations



27

4.2.2 Tonality and INP modifying factors

The INP provides additional guidance and criteria for assessing noise emission from sources with “annoying characteristics” such as tonality, impulsiveness, intermittency, irregularity or dominant low-frequency content. Penalties of up to a maximum of 10 dB(A) may be applied where the subject noise has such characteristics at the receiver. The characteristics of noise impacts at receivers have been assessed in Section 5.3.3.4.

4.2.3 Event noise

The Noise Guide for Local Government (NGLG) (DECCW, 2010) notes that Clause 90 of the Protection of Environment Operations (POEO) (General) Regulation 1997 makes the EPA the responsible authority for environmental noise emissions from outdoor concerts, festivals and cinematic or theatrical events using sound amplification equipment with 200 or more people.

In order to manage noise emissions from the operation of the Proposal, Western Sydney Stadium would be expected to develop and implement a Noise Management Plant (NMP).

The NMP would comprise the following three elements:

1. Preventive management – details of mitigation of noise impacts prior to the event such as stage and speaker orientation, barriers, sound limitation devices, crowd management, staff training and effective community consultation before the event.

2. Reactive management – noise monitoring in real time (travellers and fixed locations), use of trigger levels set below noise emission limits, modes of communication between monitors and operators, noise mitigation in real time, complaints handling in real time and communication modes between complaints handling and operators.

3. Review mechanism – assessing the performance of:

a. community consultation (before/during /after);

b. monitoring in real time; and

c. mitigation.

The results of reviews should be used to inform the development and implementation of recommendations that will improve performance over time (continuous improvement).

An integral part of the NMP will be to recommend appropriate environmental noise emission criteria for large entertainment events. The NGLG states:

There are no hard and fast rules to apply when developing noise limits for these types of events, and what is appropriate will depend upon the particular circumstances. Typically, unless the venue is very remote, it is not possible to establish noise limits that prevent annoyance at every residence. However, noise limits can prevent the noise levels from being any higher than necessary.

AECOM has completed a review of noise limits in place for other Sydney venues and concert noise management guidelines from other Australian States and the UK. Based on this review, the following noise goals have been determined as being appropriate to manage large event noise from the Proposal. It is recommended that assessment to these noise goals serve as a screening test for receivers affected by event noise. The application of these goals is discussed in Section 6.2.1.6.

These goals would apply over a 15 minute period at residential boundaries. The LCeq level is used to control low frequency noise as defined in the INP. Table 15 Environmental noise emission goals for events

Major sporting events Major concert events

LAeq, 15 minute ≤ RBL1 + 10 dB & LCeq, 15 minute ≤ RBL1 + 25 dB

LAeq, 15 minute ≤ RBL1 + 15 dB & LCeq, 15 minute ≤ RBL1 + 30 dB

Notes:

1. RBL is based on event hours of 2:00 pm to 12:00 am as presented in Table 5.

2. Up to a maximum of LAeq 75 dB(A) and LCeq 90 dB(C)

1. RBLs based on event hours presented in Table 5.

In addition, it is recommended that 5 dB be added to the INP criteria for commercial, industrial and recreational receivers (refer to Table 13) for ‘major events’.

4.3 Sleep disturbance criteria The INP has been updated with the INP application notes which discuss sleep disturbance and its assessment.

To minimise the risk of sleep disturbance as a result of industrial type operations during the night-time period, the INP application notes recommend that, the LA1(1 minute) noise level outside a bedroom window should not exceed the LA90 background noise level by more than 15 dB(A) during the night-time period (10.00 pm to 7.00 am). EPA considers it is appropriate to use this metric as a screening criterion to assess the likelihood of sleep disturbance. If this screening criterion is found to be exceeded, then a more detailed analysis must be undertaken and include the extent that the maximum noise level exceeds the background noise level and the number of times this is likely to happen during the night-time period.

The INP application notes reference the RNP for some guidance in assessing the potential for sleep disturbance. The RNP contains a review of research into sleep disturbance which represents NSW EPA advice on the subject of sleep disturbance due to noise events. It concludes that having considered the results of research to date that, ‘Maximum internal noise levels below 50-55 dB(A) are unlikely to cause awakening reactions’. Therefore, given that an open window provides approximately 10 dB in noise attenuation from outside to inside, external noise levels of 60-65 dB(A) are unlikely to result in awakening reactions.

Based on the measured background noise levels during the night, the sleep disturbance criteria for the nearest noise sensitive residential receivers are presented in Table 17.

4.4 Traffic noise criteria Noise from traffic movements to and from the Project including truck and car movements associated with the operation of the Project are assessed in accordance with the RNP. The existing Victoria Road and O’Connell Street intersection would function as the main access gate for the duration of the demolition works, allowing for the safe use of the existing road and traffic light controls without effecting movement of pedestrians, cyclists or road users. A manned vehicle access gate would be established at this main access point to prevent unauthorised access. Traffic movements would be associated with the majority of demolition activities, including dismantling of the stadium light towers, demolishing and removing large structures from the stands by mobile cranes and excavators would be wholly contained within the fenced area.

Material would be transported offsite along the following truck routes:

- east along Victoria St before heading north/south/onward to the waste depot; and/or

- south along O’Connell St before heading west/south/onward to the waste depot.

Use of the above routes would avoid the need for heavy vehicles to travel north along O’Connell Street.

Table 18 presents the road traffic noise assessment criteria for residential land use developments with potential to create additional traffic on existing roads. The external criteria are assessed at 1 metre from the affected residential building façades and at a height of 1.5 metres from the floor. Table 18 Road traffic noise assessment criteria for residential land uses

Road category Type of project/land use Assessment criteria - dB(A) Day

(7 am – 10 pm) Night

(10 pm – 7 am) Freeway/arterial/sub-arterial roads

3. Existing residences affected by additional traffic on existing freeways/arterial/sub-arterial roads generated by land use developments

LAeq, (9 hour) 55

Local roads 6. Existing residences affected by additional traffic on existing local roads generated by land use developments

LAeq, (1 hour) 55

LAeq, (1 hour) 50

To assess noise impacts an initial screening test should be undertaken by evaluating whether existing road traffic noise levels will increase by more than 2 dB(A). Where the predicted noise increase is 2 dB(A) or less, then no further assessment is required. However, where the predicted noise level increase is equal to or greater than 2 dB(A), and the predicted road traffic noise level exceeds the road category specific criterion then noise mitigation should be considered for those affected receivers. The RNP does not require assessment of noise impact to commercial or industrial receivers.

5.0 Impact Assessment

5.1 Construction (demolition) noise assessment 5.1.1 Demolition stages and scheduling

Proposed construction early works comprise demolition works of the existing stadium and swimming centre including associated infrastructure, the carpark to the west of the existing stadium and other hardstand areas. Proposed construction stages for the demolition are described in Table 19. Table 19 Demolition stages

Activity

Site establishment and enabling works

- Establishment of project office compound

- Installation of sedimentation fencing and erosion controls

- Installation of perimeter hoardings, fences and signage Site access

- Installation of vehicle gate

- Construction of vehicle access paths throughout the Site. Demolition works

- Removal of classified hazardous materials

- Removal of internal fitout

- Demolition of roof structure

- Demolition of concrete structural components

- Breaking up of concrete

- Removal of light towers

- Demolition of Parramatta Swimming Centre

Site finishing

- Clearing of debris and ensuring the Site conditions are safe

Structural demolition works will occur within standard construction hours as defined in Table 8 allowing for stoppages during meal breaks. The duration of the demolition works is expected to take four months with the structural demolition works to occur over a two to three month period.

5.1.2 Demolition sources

Noise sources and their respective sound power levels (SWLs) for each work package are shown in Table 20. These SWLs are presented as equivalent continuous levels, described by the LAeq parameter, and have been taken from data provided in Australian Standard AS 2436-2010, Guide to noise and vibration control on construction, demolition and maintenance sites and the UK Department for Environment, Food and Rural Affairs (DEFRA) “Update of noise database for prediction of noise on construction and open sites” noise database and assume equipment is modern and in good working order.

5.1.3 Modelling and conditions

In order to assess the potential noise impact, a noise model was created to represent ‘reasonable’ worst periods of the demolition works.

The demolition works have been modelled in SoundPLAN Version 7.3. The following features were included in the noise model:

- ground topography



- demolition noise sources (listed in Table 20)

Noise emissions have been modelled using an implementation of the CONCAWE algorithm with neutral metrological conditions, which is appropriate for receivers located at distances between 100 meters and 1 kilometre

There may be differences between predicted and measured noise levels due to variations in instantaneous operating conditions, plant in operation during the measurement and also the location of the plant equipment. The acoustic shielding calculated in the model due to fixed building structures would also vary as the construction equipment moves around the Site.



32

5.1.4 Demolition noise assessment

A summary of the demolition noise results is shown in Table 21 for standard construction hours. Due to the large number of nearby receivers, only those where the predicted impacts have exceeded the NMLs (refer to Table 9 and Table 10) are shown. No exceedances are predicted during site establishing and enabling works or site access works. Results are presented graphically in Appendix C.

All demolition plant listed in Table 20 have been modelled as operating simultaneously, giving a conservative worst case scenario for each demolition phase. This represents a conservative assessment with measured noise levels likely to be lower than those predicted below.

The level of impact may change depending on the final demolition methodology and further assessment would be undertaken if large changes to the demolition plant list in Table 20 are to be required..

1 Grose Street, Parramatta Medical 1 55 50 55 56 - - 1

2 Grose Street, Parramatta Medical 2 55 53 57 55 - 2 -

Results show that one residence, 1 Fleet Street, North Parramatta, is predicted to exceed standard hours NMLs by 5 dB during stadium demolition and 4 dB during Parramatta Swimming Centre demolition. It should be noted that although residences are located closer to demolition works than 1 Fleet Street, this receiver is located in NCA 2, which has an 8 dB lower NML than NCA 1, where a higher RBL was measured. No exceedances are predicted at any other receivers during demolition works.

No exceedances are predicted during any other stages of works, and no receivers are predicted to be ‘highly affected’.

Noise impacts at five non-residential receivers are predicted to exceed NMLs during demolition works. The largest exceedances of up to 18 dB are predicted at Saint Patrick’s, 1 Marist Place, Parramatta. Noise impacts may significantly affect the operation of schools, churches and medical centres presented in Table 21, and noise mitigation measures presented in Section 6.1 should be implemented.



34

5.1.4.1 Construction traffic

The number of vehicle movements generated from demolition works are anticipated to be 174 trucks over a four month period. Based on the demolition programme and deliveries required for demolition activities, it is estimated that there would be a maximum of 3-4 trucks per hour above the existing traffic volumes for the duration of the demolition works.

The existing traffic flows provided by MATRIX Traffic and Transport Data indicate over 2000 vehicles travel along O’Connell Road during standard construction hours on average, and over 900 travel along Victoria Road, which represent the two likely routes for demolition traffic entering the Site.

In assessing feasible and reasonable mitigation measures, an increase of up to 2 dB(A) represents a minor impact that is considered barely perceptible to the average person.

The increase in traffic as a result of the demolition works would result in an increase in traffic noise levels less than 1 dB(A) and would not be considered perceptible to the average person. No mitigation of demolition generated road traffic noise is considered necessary.

5.2 Construction vibration Jackhammers to be used during demolition have been identified as being vibration intensive. Table 22 recommends safe working distances to minimise disturbance to occupants of nearby buildings and is based on British Standards BS6472 and BS7385 (Construction Noise Strategy, 2012, Transportation Construction Authority). Table 22 Recommended safe working distances for vibration intensive plant

Plant Rating/Description Safe working distance

Cosmetic damage Human response

Small Hydraulic Hammer (300 kg – 5-12T excavator) 2 m 7 m

Medium Hydraulic Hammer (900 kg – 12-18T excavator) 7 m 23 m

Large Hydraulic Hammer (1,600 kg – 18-34T excavator) 22 m 73 m

Jackhammer Handheld 1 m nominal Avoid contact with structure

For the demolition works there are no receivers located within the recommended safe working distances presented in Table 22. If the safe working distances are complied with, no adverse impact from the vibration intensive works are likely in terms of human response or cosmetic damage. One active recreation venue, Parramatta Swimming Centre – O’Connell Street, Parramatta, is located approximately 100 metres from the existing Parramatta Stadium, with two swimming pools located as close as 15 metres to the existing Parramatta Stadium. Although this Centre is to be demolished as part of the early works, this is scheduled after the demolition of the stadium, and the Swimming Centre will continue to operate during the demolition of the stadium. There may be some risks from vibration intensive equipment operating within the safe working distances from the pools, thereby creating a risk of cosmetic or structural damage to the pools. Vibration mitigation measures are presented in Section 6.1.2.

5.3 Operational noise assessment 5.3.1 Operational scenarios and modelling assumptions

The Project is proposed to seat a 30,000 capacity crowd and host public events such as large sporting matches and music concerts. Operational noise has been modelled based on three worst case 15 minutes scenarios representing the loudest three events taking place within the proposed stadium.

Live music with amplified support

84 123

Sporting event AFL game AAMI Stadium (30,4000 capacity), 2004 – crowd noise

Measurements are based on measurements previously conducted by AECOM (formerly Bassett) for similar events at large stadiums (AA0998-SM005.REP, Bassett Acoustics, November 2006 & AA0998-A8K02RP, Bassett Acoustics, November 2008). It should be noted that the sound pressure level of 103 dB(A) for a music event and 94 dB(A) for a sporting event represent conservatively high levels which are unlikely to be sustained for more than 15 minutes and are representative of worst case scenarios.

The overall sound power levels of the stadium presented in Table 23 have been applied across the entire crowd area, based on the conservative assumption that sound pressure levels in Table 23 will be constant across the crowd.

The proposed stadium has been modelled based on Western Sydney Stadium Draft Concept Proposal drawings provided by CHROFI Architects (Western Sydney Stadium Concept Proposal, June 2016).

The noise model has assumed an open donut-shaped roof with full-height stadium walls surrounding the seating and extending to the roof structure, with a 3D rendering presented in Figure 4. It should be noted that at this concept stage of the stadium design no details regarding penetrations in the perimeter walls for ventilation or otherwise are available. Should penetrations to the perimeter walls or roof be introduced during later development of the design, noise emissions from the stadium may increase.

The noise sources within the stadium have been modelled as distributed evenly across the crowd seating up to a height of RL +32000 based on preliminary concept design drawings for seating heights.



36

Figure 4 3D rendering of noise model

5.3.2 Modelling and conditions

In order to assess the noise impact from the proposed stadium during operation, a noise model was created to represent ‘reasonable’ worst periods of events to take place at the stadium.

The upgrade works have been modelled in SoundPLAN Version 7.3. The following features were included in the noise model:

- ground topography



- operational noise sources (listed in Table 23)

Noise emissions have been modelled using an implementation of the CONCAWE algorithm with neutral metrological conditions, which is appropriate for receivers located at distances between 100 metres and 1 kilometer.

5.3.3 Operational noise assessment

5.3.3.1 Event noise

A summary of predicted operational noise results are presented in Table 23. Results are presented graphically in Appendix C. A full set of operational noise impacts are presented in Appendix D.

Maximum predicted LAeq noise levels at residential receivers within each NCA are presented in Table 24.

Sporting event 63 64 53 53 Music concert - Rock 72 73 62 62 Music concert - Classical 53 54 <45 <45

Results show noise levels up to 73 dB(A) are predicted within NCA 2 during rock music events, with noise levels of 72 dB(A) predicted in NCA 1 and levels of 62 dB(A) predicted in NCAs 3 and 4. These levels are based on the measured noise level presented in Table 23, which represent conservative worst case scenarios.

A summary of the number of residences exceeding noise goals for large events, shown in Table 15, are presented in Table 25. Table 25 Leq(15min) event noise assessment

Exceedance, dB Number of residences exceeding Leq(15min), dB(A) noise goals

>0 176 207 400

Music concert - Classical

>10 0 0 0

>5 0 0 0

>0 0 0 0

Results show no exceedances are predicted during a classical concert as an example of a quieter music event.

Approximately 200 receivers are predicted to exceed noise goals during the day, approximately 230 in the evening and up to 400 at night during a rock concert, an example of a louder music event.

During a the worst case 15 minute period of a sporting event, the number of residences predicted to exceed noise goals are approximately 90 and 110 during the day and evening, and up to 190 at night. These levels are unlikely to be sustained for an entire 15 minute period.

The magnitude of these exceedances varies, with more than half of the predicted exceedances less than 5 dB above noise goals.

The significance of the results presented in Table 25 and the recommended course of action is discussed in Section 6.2.1.6.



38

5.3.3.2 Discussion

Although Table 24 shows the highest LAeq(15 min) levels are predicted in NCA 1, a larger number of exceedances are predicted in NCA 2, NCA 3 and NCA 4 due to lower measured RBLs in these areas, hence more stringent noise goals. The largest number of exceedances are predicted in NCA 2, located to the north east of the Site.

The magnitude of these exceedances does vary, with a large number of exceedances within 2 dB of noise goals, considered a ‘minor’ exceedance barely perceptible to the average person. Consideration should also be given to the frequency of these events, with up to 42 sporting events, and 1 final event, modelled as a music concert, scheduled for a calendar year under the Project.

It should be noted that these levels represent worst case scenarios as discussed in Section 5.3.1, and are unlikely to be sustained for more than a 15 minute period.

Recommended management measures for receivers exceeding event noise goals are presented in Section 6.2.1.6.

5.3.3.3 Predicted and existing noise impacts comparison

Noise monitoring was conducted during Australian Supercross Championship on 8 November 2008 at Parramatta Stadium by PCCD Consultancy and Design (EN-MS-081108AJ, December 2008).

A comparison between noise levels from crowd cheering measured during the event and predicted noise levels is presented in Table 26. Table 26 Existing and predicted noise impacts comparison

Assessment receiver address

Measured Lmax dB(A) Predicted Lmax dB(A)1 Australian Supercross Championship – crowd cheering, 2008

Sporting event, modelled crowd cheering

Music concert – amplified rock music

6 Victoria Road 77 75 84

2 Ross Street 68 - 73 68 77 Notes

1. Lmax levels have been derived by adding 11 dB to predicted Leq levels. 11 dB represents the average difference between Leq

values and Lmax values measured at AAMI stadium by AECOM (AA0998-SM005.REP, 2006, AA0998-A8K02RP, 2008).

Results show measured noise impacts during the Supercross Championship from crowd cheering are within 2 dB of predicted noise impacts from crowd cheering at a sporting event at both receivers. 2 dB represents the generally accepted tolerance of accuracy for noise modelling results, hence these results are considered to validate the noise model.

Loudest noise impacts from rock concerts are predicted to be up to 7 dB louder than existing noise levels from crowd cheering, however this is based on conservative assumptions, such using the loudest measured music noise level applied across the entire crowd seating area. These results are considered reasonable, as the sound pressure level in the crowd of a rock concert of 103 dB(A) is 9 dB louder than that of crowd cheering at a sporting event, with a sound pressure level of 94 dB(A), as shown in Table 23.

5.3.3.4 Low frequency noise and tonal noise

Low frequency and tonal noise can be a feature of amplified music noise. During sporting events the most significant noise emissions would be crowd noise. Vocal noise is typically spread over the mid-high frequency range, therefore low frequency noise would not be an issue during sporting events. As the concert may give rise to noise with low frequency characteristics, it is recommended that this is indicated to residents during community notification.

5.3.3.5 Mechanical plant noise

Mechanical plant selections, car park details and loading dock locations and activities have not been finalised at this stage of the Project. Noise emissions from these sources shall be assessed and treatment recommended if necessary during Stage 2 of the Project.



39

5.3.4 Sleep disturbance assessment

A summary of sleep disturbance assessment results from event noise are presented in Table 27. A modelled difference between LAmax and Leq levels of 11 dB was used bas the average difference between Leq values and Lmax values measured at AAMI stadium by AECOM (AA0998-SM005.REP, 2006, AA0998-A8K02RP, 2008). Table 27 Sleep disturbance assessment summary

>10 472 1 64 60 0 0

>20 42 0 1 0 0 0

Results show a significant number of residences are predicted to exceed both the sleep disturbance screening criteria and the sleep awakening criteria during a rock concert. Up to 418 residences are predicted to exceed the screening criteria during loud sporting events, with 97 residences predicted to exceed sleep awakening criteria. No receivers are predicted to exceed sleep awakening criteria during a classical concert.

5.4 Additional road traffic Vehicles on a game day are expected to approach the stadium carpark from O’Connell Street and Victoria Road. The carpark will have a capacity of up to 500 bays. Predicted traffic volumes for a game day and an average weekday are provided below in Table 28. Table 28 Operational road traffic assessment

As shown in Table 28 the largest increase in volumes is northbound on O’Connell Street (1% increase). Due to the small number of additional vehicles the increase in noise as a result of traffic generated by the Proposal would be inconsequential (less than 1 dB(A)) on O’Connell Street and Victoria Road. Therefore, the issue of impacts caused by operational traffic need not be considered any further.

6.0 Mitigation and Management Measures

6.1 Construction (demolition) noise and vibration recommendations This section of the report presents demolition noise and vibration mitigation measures to be considered for implementation to minimise and manage demolition works noise impacts.

The demolition noise and vibration assessment presented in Chapter 5.1 of this report detailed a number of exceedances of the noise management levels within the study area. These were predicted as a result of various different demolition activities. As a result of these exceedances, the following generic and receiver specific mitigation measures have been identified.

6.1.1 Construction noise and vibration management plan

A Construction Noise and Vibration Management Plan (CNVMP) should be prepared. The CNVMP should include the following:

- Identification of nearby residences and other sensitive land uses.

- Description of approved hours of work.

- Description and identification of all demolition activities, including work areas, equipment and duration.

- Description of what work practices (generic and specific) would be applied to minimise noise and vibration.

- A complaints handling process.

- Noise and vibration monitoring procedures.

- Overview of community consultation required for identified high impact works.

The CNVMP should include consideration of the following issues:

- Cumulative construction noise impacts.

- Construction noise fatigue.

The cumulative noise impacts of nearby major projects should be further considered by the contractor when a detailed demolition schedule becomes available for the Proposal. In addition the contractor should periodically check for other approved construction projects should affect noise sensitive receivers impacted by the Proposal. Feasible and reasonable mitigation measures should be detailed in the CNVMP and updated as necessary.

Feasible and reasonable mitigation measures should be detailed within the CNVMP to manage predicted noise levels at sensitive receivers. Consultation with the affected community should also occur prior to and during demolition works.

6.1.1.1 Community consultation and complaints handling

All residents predicted to be impacted by noise from the proposed demolition works (i.e. where the demolition noise management levels (NML) are exceeded) should be consulted with about the Proposal prior to the commencement of the particular activity. The highest consideration should be given to those residences and businesses that are predicted to be most affected as a result of the demolition works.

The information provided to the residents should include:

- An overview of the demolition works to be undertaken

- Programmed times and locations of demolition work

- The hours of proposed works

- Demolition noise and vibration impact predictions

- Demolition noise and vibration mitigation measures being implemented on site.

Community consultation regarding demolition noise and vibration should include a 24 hour hotline and complaints management process.



41

6.1.1.2 Work practices

Induction and training should be provided to relevant staff and sub-contractors outlining their responsibilities with regard to noise and vibration.

6.1.1.3 Demolition hours and work scheduling

It is understood that all demolition works would take place during standard construction hours. Should any out of hours work be required, details of this work should form part of the CNVMP.

Noisy work (i.e. demolition works) should be scheduled to be undertaken during the standard hours as far as possible. Noisy activities that cannot be undertaken during standard construction hours should be scheduled as early as possible during the evening and / or night-time periods.

Deliveries should be carried out during standard construction hours where feasible and reasonable.

Consideration should be given to demolition timetabling to minimise noise impacts, namely to nearby schools or churches. This could include the use of respite periods.

6.1.1.4 Respite

A protocol should be developed to identify the need for and provision of respite measures for residential receivers in accordance with the ICNG. Respite measures may include the restriction to the hours of demolition activities resulting in impulsive or tonal noise (such as jackhammering), or other appropriate measures agreed between the contractor and residential receiver such as alternative accommodation. The protocol should form part of the CNVMP.

6.1.1.5 Construction traffic

The following measures should be implemented to reduce and manage noise and vibration impacts:

- Truck drivers should be advised of designated vehicle routes, parking locations, acceptable delivery hours or other relevant practices (i.e. minimising/restricting the use of engine compression brakes, and no extended periods of engine idling).

- Deliveries and spoil/waste removal should be planned to avoid queuing of trucks on or around the compounds.

- Construction sites should be arranged to limit the need for reversing associated with regular / repeatable movements (e.g. trucks transporting spoil) to minimise the use of reversing alarms.

- Where feasible and reasonable, non-tonal reversing alarms should be used, taking into account the requirements of the Workplace Health and Safety legislation.

Spoil and waste should be moved during the day where practical.

6.1.1.6 Plant and equipment selection and location

The selection of plant and equipment can have a significant impact on demolition noise levels. Appropriate plant should be selected for each task where possible to minimise the noise contributions.

Equipment should be regularly inspected and maintained to ensure it is in good working order.

Plant should be located on site with as much distance as possible between the plant and noise sensitive receivers.

6.1.1.7 Noise monitoring

Noise monitoring program should be implemented to assist in confirming and controlling the site specific potential for disturbance at particularly sensitive localities at the commencement of activities and periodically during the demolition program as the works progress. The results should be reviewed to determine if additional mitigation measures are required. All measurements should be undertaken in accordance with Australian Standard 1055.1-1997 – Acoustics – Description and measurement of environmental noise, Part 1: General procedures.

A noise monitoring program should be presented in the CNVMP.

If regenerated noise is reported to be a problem during vibration intensive works, attended and / or unattended noise measurements should be undertaken in the relevant building spaces to determine the level of regenerated noise.

6.1.2 Construction vibration

Although adverse impacts due to vibration are unlikely, in some circumstances demolition activity within the safe working distance cannot be avoided due to the work required and the prevalent geological site conditions. These conditions may not be fully understood until work has commenced.

Parramatta Swimming Centre pools are located approximately 15 metres from the existing Parramatta Stadium site.

Equipment should be maintained and operated in an efficient manner, in accordance with manufacturer’s specifications, to reduce the potential for adverse vibration impacts.

Should vibration intensive activities that occur within the safe working distances, smaller, less vibration intensive equipment with smaller required safe working distances should be used over a longer period in lieu of larger equipment with large safe working distances.

Should works within safe working distances presented in Table 22 be unavoidable, vibration monitoring is recommended to ensure vibration levels impacting the pool do not exceed structural damage vibration limits presented in Table 11.

6.1.2.1 Supplementary vibration monitoring

If the use of vibration intensive plant cannot be avoided within the safe working distance for cosmetic damage the following procedure should occur as a minimum:

- Notification of the works to the Swimming Centre

- Works should not proceed until attended vibration measurements are undertaken.

If ongoing works are required a temporary relocatable vibration monitoring system should be installed, to warn operators (via flashing light, audible alarm, short message service (SMS) etc.) when vibration levels are approaching the cosmetic damage objective.

6.2 Operational noise and vibration recommendations Results presented in Section 5.3 show that during the daytime and evening, the loudest noise events to be hosted at the stadium are represented by a rock concert, with up to 207 receivers are predicted to exceed large event noise goals. During the night time, between 10:00 pm and 12:00 am, up to 400 residences exceed event noise goals, and around 500 residences are predicted to exceed the sleep awakening noise goals.

By comparison, up to 89 receivers are predicted to exceed daytime and evening noise goals during sporting events, and up to 190 receivers are predicted to exceed night time noise goals.

The development and implementation of a Noise Management Plan (NMP) is therefore recommended for all events taking place at the stadium.

It is recommended that the NMP incorporates the following elements.

6.2.1 Preventative management

6.2.1.1 Design considerations

It is recommended that opportunities to minimise acoustic impacts are considered during the detailed design of the stadium. This includes design of roof structure.

6.2.1.2 Requirements on limits to the days and times of events

Restrictions to the number of events per year will provide respite measures for residential receivers. Limiting the times of major event to daytime and / or evening hours when the community is least sensitive to noise will minimise the disturbance to the community and prevent sleep disturbance to surrounding residences.

6.2.1.3 Requirement for notice to consent authorities

Current NMP conditions require Venues NSW to notify consent authorities of details of upcoming events. These requirements include notification of Environmental Protection Authority and City of Parramatta Council’s Development Services Unit of any planned noisy events, by registered mail, at least 60 days before the events..



43

It is recommended the notice to the consent authorities advise of:

- a nature (description) and size of (expected crowd attending) an event;

- a date and time (duration) of the event, including preliminary practice sessions and/or rehearsals;

- Western Sydney Stadium (WSS) Hot Line (telephone number) for lodgement of noise complaints; and

- a name and telephone number of the Venue Manager, who will be responsible for compliance with noise limits.

6.2.1.4 Notice to the community including residents and businesses

Similarly, current NMP conditions require Venues NSW to notify all residential premises within 1 kilometre of Parramatta Stadium and the residential premises listed in the NMP of any planned noisy events by a letterbox drop at least 60 days before the events.

It is recommended the notice to the residential and commercial premises advise of:

- a nature (description) and size of (expected crowd attending) a major event;

- a date and time (duration) of the event, including preliminary practice sessions and/or rehearsals;

- A Hot Line (telephone number) for lodgement of noise complaints;

- the Noise Management Plan available on agency’s website; and invite post-event feedback.

6.2.1.5 Setup of sound amplification systems

An optimal setup of sound amplification systems should be sought in consultation with suitably qualified acoustic consultants in order to minimise noise impacts at potential worst affected receivers.

Sound systems may also include noise limiters to prevent exceedance of established noise limits at nearby receivers, or trigger levels as indication of exceedances of noise limits. The setting of these systems will require consultation with suitably qualified acoustic and AV consultants.

This should be investigated as part of Stage 2 works.

6.2.1.6 Noise limits during events

Recommended noise goals for large events are presented in Table 16. It is recommended that assessment to these noise goals serve as a screening test for receivers affected by event noise. Compliance with these recommended goals indicates no significant undue disturbance to the community, in consideration of the infrequency and nature of noise emissions. No further noise treatment is therefore recommended should receivers comply with these noise goals.

Receivers predicted to exceed these noise goals should be eligible for the reactive management measures presented in Section 6.2.2.

6.2.2 Reactive management

6.2.2.1 Noise monitoring requirements

Requirements for noise monitoring during noisy events should be outlined in the NMP, including:

- Location of noise measurements

- Instrumentation

- Monitoring times

- Noise descriptors

- Personnel qualifications

An outline to reporting requirements should also be included, outlining information required in the report, such as confirmation of conditions being met.

6.2.2.2 Complaints handling

During noisy events a hotline should be made available to the public for lodgement of noise complaints.



44

The hotline should notify without delay the acoustical consultants carrying out measurements of noise, who should immediately follow complaints with noise measurements carried out at locations of complainants.

A register of all noise complaints received during noisy events should be maintained.

6.2.3 Review mechanism

6.2.3.1 Community feedback

Occupiers of the residential and commercial premises should be encouraged to express their opinion on the impact of noise emanating from noisy events held at WSS and provide suggestions on minimising the impact through letter box drops. The general public should similarly be encouraged through a website and in local newspapers.

6.2.3.2 Noise Management Plan publicly available

The NMP should be made publicly available on a website alongside information on upcoming noisy events.

6.2.3.3 Review of Noise Management Plan

A regular review and update the Noise Management Plan should be conducted taking into account:

- complaints regarding noise;

- results of the community consultation; and

- recommendations from the consent authorities and acoustical consultants engaged in monitoring of noise during the events.



45

7.0 Conclusion A noise and vibration impact assessment has been conducted by AECOM in order to assess impacts on the community from Stage 1 of the Project.

Criteria

Noise monitoring was conducted at four locations in order to determine RBLs for Noise Catchment Areas. Based on these measurement results, demolition noise management levels and operational noise goals were established for the Project and are presented in Section 4.1 and 4.2.

Demolition

Demolition works are anticipated to take place during standard construction hours. Three demolition scenarios representing major works as part of the Proposal were modelled. Modelled predictions were assessed against established NMLs to determine exceedances at residences and non-residential receivers.

Demolition noise impacts were predicted to exceed NMLs at some residential and non-residential receivers during the demolition phase of works. No receivers were predicted to exceed NMLs during other demolition work phases, and no residential receivers were predicted to be ‘highly affected’.

Operation

Operational noise from the proposed stadium was modelled based on draft concept proposal drawings. Stadium walls were modelled as full height.

Three operational scenarios were modelled to represent the three loudest events that may take place at the proposed stadium; a rock concert, a classical concert and a large sporting event. Noise measurements previously conducted by AECOM were used to derive crowd and music sound power levels which were used in the operational noise model. Events were assumed to take place during the day, evening and night between the hours of 2:00 pm and 12:00 am.

Sporting events are scheduled to take place up to 42 times per calendar year under the Project. Noise impacts from a typical sporting event at proposed stadium are predicted to reach 64 dB(A) at the worst affected receivers, approximately equal to current crowd noise levels from the existing Parramatta Stadium. These levels are based on a worst case scenario where crowds are cheering for a 15 minute period, and measured noise levels from the proposed stadium are likely to be lower than those predicted.

The loudest events to take place at the proposed stadium, rock concerts, are predicted to reach levels of 72 dB(A), predicted to be 7 dB higher than impacts from current crowd noise from the existing Parramatta Stadium. Sporting events are predicted to be within 2 dB of noise levels from the existing Parramatta Stadium.

Event noise goals have been recommended in Table 15, however these goals should serve as a screening test. Compliance with these goals indicates no undue disturbance to the community is likely. Receivers which exceed these goals should be eligible for noise mitigation measures. This is discussed in Section 6.2.1.6.

Approximately 90 receivers are predicted to exceed day and evening noise goals during a sporting event, and up to 190 receivers during the night. 75% of these exceedances are predicted to be less than 5dB above noise goals. Approximately 200 receivers are predicted to exceed daytime and evening noise goals during the loudest likely music concert scenario, a rock concert, and up to 400 exceedances are predicted at night. Approximately half of these exceedances are less than 5 dB.

A sleep disturbance assessment was conducted based on both sleep disturbance screening criteria and sleep awakening criteria. Up to 97 residences were predicted to exceed sleep awakening criteria during a sporting event, and up to 508 exceedances were predicted during rock concerts.

Acoustic Terminology



A-1

Appendix A Acoustic Terminology The following is a brief description of acoustic terminology used in this report.

Sound power level The total sound emitted by a source

Sound pressure level The amount of sound at a specified point

Decibel [dB] The measurement unit of sound

A Weighted decibels [dB(A]) The A weighting is a frequency filter applied to measured noise levels to represent how humans hear sounds. The A-weighting filter emphasises frequencies in the speech range (between 1kHz and 4 kHz) which the human ear is most sensitive to, and places less emphasis on low frequencies at which the human ear is not so sensitive. When an overall sound level is A-weighted it is expressed in units of dB (A).

Decibel scale The decibel scale is logarithmic in order to produce a better representation of the response of the human ear. A 3 dB increase in the sound pressure level corresponds to a doubling in the sound energy. A 10 dB increase in the sound pressure level corresponds to a perceived doubling in volume. Examples of decibel levels of common sounds are as follows:

0dB(A)

30dB(A)

40dB(A)

50dB(A)

70dB(A)

80dB(A)

90dB(A)

100dB(A)

110 dB(A)

115dB(A)

120dB(A)

Threshold of human hearing

A quiet country park

Whisper in a library

Open office space

Inside a car on a freeway

Outboard motor

Heavy truck pass-by

Jackhammer/Subway train

Rock Concert

Limit of sound permitted in industry

747 take off at 250 metres

Frequency [f] The repetition rate of the cycle measured in Hertz (Hz). The frequency corresponds to the pitch of the sound. A high frequency corresponds to a high pitched sound and a low frequency to a low pitched sound.

Equivalent continuous sound level [Leq]

The constant sound level which, when occurring over the same period of time, would result in the receiver experiencing the same amount of sound energy.

Lmax The maximum sound pressure level measured over the measurement period

Lmin The minimum sound pressure level measured over the measurement period

L10 The sound pressure level exceeded for 10% of the measurement period. For 10% of the measurement period it was louder than the L10.

L90 The sound pressure level exceeded for 90% of the measurement period. For 90% of the measurement period it was louder than the L90.



A-2

Ambient noise The all-encompassing noise at a point composed of sound from all sources near and far.

Background noise The underlying level of noise present in the ambient noise when extraneous noise (such as transient traffic and dogs barking) is removed. The L90 sound pressure level is used to quantify background noise.

Traffic noise The total noise resulting from road traffic. The Leq sound pressure level is used to quantify traffic noise.

Day The period from 0700 to 1800 h Monday to Saturday and 0800 to 1800 h Sundays and Public Holidays.

Evening The period from 1800 to 2200 h Monday to Sunday and Public Holidays.

Night The period from 2200 to 0700 h Monday to Saturday and 2200 to 0800 h Sundays and Public Holidays.

Assessment background level [ABL]

The overall background level for each day, evening and night period for each day of the noise monitoring.

Rating background level [RBL] The overall background level for each day, evening and night period for the entire length of noise monitoring.
