Executive Summary Cross Yarra Partnership (CYP) has been contracted by Melbourne Metro Rail Authority (MMRA) to design, build and maintain the tunnels and stations for the Metro Tunnel Project, (the Project). The project includes two nine-kilometre train tunnels and five new underground train stations, linking the north-west Sunbury rail corridor and the south-east Cranbourne/Pakenham rail corridor, unlocking additional capacity in the existing City Loop. The five new underground stations are located at Arden, Parkville, CBD North, CBD South and Domain.

This report details an Environmental Risk Assessment (ERA) of the additional Project Land proposed by CYP for Melbourne Metro. Effective environmental risk management is a continuous, collaborative and forward-looking process. It aims to anticipate potential impacts so that project related activities can be planned and managed, and were applicable, mitigate adverse impacts. Environmental risk is a function of the likelihood of an adverse event occurring and the consequence of the event. CYP will continue to apply a robust and transparent environmental risk assessment across all phases and components of the Project including construction and operational phases.

The project has already undergone an extensive and robust planning assessment process. As part of this, MMRA published an Environment Effects Statement (EES) and draft Planning Scheme Amendment that included an integrated assessment of the potential environmental, social, economic and planning impacts of the project, and the approach to managing these impacts. In developing the EES, MMRA undertook a comprehensive engagement program to seek input from stakeholders and the community. This included stakeholders and the community having the opportunity to provide formal submissions during a public exhibition period, which were then presented to an Inquiry and Advisory Committee. The key focus of the Committee’s review, findings and recommendations was the planning and environmental control framework for the Project, which resulted in a report prepared for the Minister for Planning. In December 2016, the Minister for Planning released his Assessment of the environmental effects of the project. The Assessment was undertaken in line with the Environment Effects Act 1978 and completed the EES process. The Minister’s Assessment concludes that the environmental effects of the Project are acceptable, provided appropriate mitigation and management is implemented. The Minister subsequently approved a Planning Scheme Amendment (PSA) and Incorporated Document for the project. The Incorporated Document, under Section 4.7 Environmental Management Framework (EMF), required an EMF to be approved. The EMF ensured the inclusion of Environmental Performance Requirements (EPRs), which address sixteen environmental factors. This encompassing process will be referred throughout as the EES and PSA processes.

The EPRs measurements ensure that there is a clear, unambiguous and transparent set of controls in place to guide Project delivery. The EPRs define the project-wide environmental outcomes that must be achieved during design, construction and operation of Melbourne Metro, (regardless of the design solutions adopted). While it will not be possible to avoid all effects and impacts, the recommendations and outcomes of the public submission, Inquiry and Ministerial Assessment; found the EPRs should provide an effective way to manage potential risk.

It is therefore these EPRs that will be used to assess the ability for CYP to appropriately manage and mitigate the proposed changes outside of Project Land. As a consequence of this an updated ERA and Environmental Impact Assessment (EIA) has been undertaken for the proposed changes to the Project Land.

The CYP changes predominately relate to the provision of underground support structures, additional station connections and temporary road occupations that affect surface land. Similar to the process undertaken by MMRA for the initial EES and PSA processes, CYP have undertaken a robust and transparent environmental risk assessment process for the project. The initial desktop risk assessment identified the need for this Historical Cultural Heritage impact assessment report.

The assessment finds that the proposed CYP changes to the approved Project Land as they affect historical heritage values do not on the whole constitute a significant departure from the works assessed under the EES and PSA processes. These changes generally represent a realignment of works of a similar nature assessed under the EES and PSA processes. EPRs established through the EES and PSA processes and assessment remain relevant and applicable to the proposed changes. In the majority of cases, there is no appreciable increase in direct physical impact to listed heritage places as the majority of works proposed are subsurface (rail tunnel alignment, additional underground support structures, pedestrian/construction adits) or superficial in nature (additional road surface works). The principal exception to this is the proposed works in relation to the proposed connection to Flinders Street Station which will involve works with the potential to affect significant fabric on the station platforms as well as the pedestrian subway incorporating Campbell Arcade and the Degraves Street underpass.

This impact assessment report has determined that all potential impacts to historical cultural heritage, arising as a result of the changes to the approved Project Land, can be dealt with effectively by the existing project EPR’s.

The risk assessment process has resulted in residual risk ratings of either a low or very low rating for all aspects except one. A ‘Medium’ risk was registered in CBD South for the ‘damage to buildings, heritage place or place of known or potential historical cultural heritage, impacting on cultural heritage values’ due to the access to Flinders Street Station and lift facilities to station platforms at CBD South.

1 Introduction Cross Yarra Partnership (CYP) has been contracted by Melbourne Metro Rail Authority (MMRA) to design, build and maintain the tunnels and stations for the Metro Tunnel Project (the project). The project includes two nine-kilometre train tunnels and five new underground train stations, linking the north-west Sunbury rail corridor and the south-east Cranbourne/Pakenham rail corridor, unlocking additional capacity in the existing City Loop. The five new underground stations are located at Arden, Parkville, CBD North, CBD South and Domain.

The project has undergone an extensive and robust planning and environmental assessment process. In 2016 MMRA exhibited and received public comment on:

• An Environment Effects Statement (EES) that presented an integrated assessment of the potential environmental, social, economic and planning impacts of the project, and the proposed approach to managing these impacts.

• A Draft Planning Scheme Amendment (PSA) to facilitate the use and development of the project, as well as, establishing a mechanism to protect the tunnels, stations and associated infrastructure from potential adverse effects of development in their vicinity.

In December 2016, the Minister for Planning released his assessment of the environmental effects of the project. The Minister subsequently approved a PSA (GC45) for the project which, among other things, inserted the Melbourne Metro Rail Project Incorporated Document (December 2016) into the Melbourne, Port Phillip, Stonnington and Maribyrnong Planning Schemes and gave legal effect to the Incorporated Document through clause 52.02 of each of these Schemes. The project’s Incorporated Document was subsequently amended by PSA GC67 to facilitate the Park Street, South Melbourne tram stop. The latest Incorporated Document is Melbourne Metro Rail Project Incorporated Document (May 2017).

The EES and PSA processes assessed a Concept Design and indicative construction methodology for that project that was prepared by MMRA. Following appointment as the project contractor, CYP proposes a series of enhancements and changes to the Concept Design as exhibited in the EES and PSA processes that will deliver improvements in accessibility and construction and operational efficiencies.

Some of these CYP enhancements necessitate a need to change the boundary of the Project Land, which can only be done by a planning scheme amendment to vary the plans appended to the Incorporated Document. The CYP changes predominately relate to the provision of underground support structures, additional station connections and temporary road occupations that affect surface land.

A PSA to amend the Incorporated Document is an appropriate planning response to the project changes, as the alternative would be to seek either multiple planning permits or planning scheme amendments. The CYP design changes affect land located both inside and outside of the approved Project Land.

1.1 Purpose of this Report

The purpose of this report is to assess the potential positive and adverse historic heritage impacts of the changes to the approved Project Land resulting from CYP design changes.

This report assesses new potential impacts arising during construction and operation, and includes consideration of both direct and indirect impacts.

A heritage place which is included on the Victorian Heritage Register (VHR) is subject to the separate requirements and processes of the Heritage Act 2017. This includes VHR listed places that are affected by a Heritage Overlay under the Melbourne Planning Scheme and by the Project Land changes. Where required, approvals and other consents would be sought from Heritage Victoria.

Locally listed heritage places that are affected by a Heritage Overlay under the Melbourne Planning Scheme have been identified and addressed in Section 4 and the Land Use Planning Impact Assessment Report. These places will be subject to the requirements of the proposed Incorporated Document.

This report will support MMRA’s proposed planning scheme amendment (GC82), which includes the additional Project Land in an updated Incorporated Document.

This report will support MMRA’s proposed planning scheme amendment (GC82), which will include the additional Project Land in an updated incorporated document.

1.2 Project Description

The physical infrastructure proposed to be constructed as part of Melbourne Metro, and assessed in the initial EES and PSA processes, broadly comprises:

• Twin nine-kilometre rail tunnels from Kensington to South Yarra connecting the Sunbury and Cranbourne/ Pakenham railway lines to form the new Sunshine-Dandenong Line (with the tunnels to be used by electric trains)

• Rail tunnel portals (entrances) at Kensington and South Yarra

• New underground stations at Arden, Parkville, CBD North, CBD South and Domain with longer platforms to accommodate longer High Capacity Metro Trains (HCMTs). The stations at CBD North and CBD South would feature direct interchange with the existing Melbourne Central and Flinders Street Stations respectively

• Train/tram interchange at Domain station.

The following sections outline the extent and location of CYP design changes, which will result in modifications of the approved Project Land, as exhibited in GC45 and GC67. The changes, or project components generally relate to the following works at Parkville Station, CBD North Station and CBD South Station:

• Rail alignment: The modified rail alignment represents a change in horizontal or vertical alignment (i.e. change in track geometry).

• Underground support structures: Underground support structures are ancillary structures that are used for stabilisation of a primary structure such as a shaft, station box or tunnel: ▪ Usually rock bolts are shorter in length and used predominantly along the rail tunnels. ▪ Rock anchors are longer in length and can be used to support shafts at the stations. In both instances, each stabiliser can sit 1.5 to 2 metres apart and protrude at an angle.

• Note: The underground support structures will be used temporarily by CYP to provide ground support during the construction phase and then will remain in situ pending removal or modification as part of any future redevelopment by others.

• Pedestrian adits: A pedestrian adit is a permanent underground passage that connects the tunnel or station to a ground level access point and has a primary purpose of facilitating passenger movements.

• Construction adits: A construction adit is an underground passage that will connect the station to a ground level access point. It is typically used for the movement of equipment, materials and excavated material. It can also be used for storage purposes.

• Flinders Street Station platform works: Additional lifts connecting the station platforms to the Degraves Street Underpass/Campbell Arcade Underpass.

• Additional road areas: Additional road areas are road reserves required for construction management, together with temporary and legacy road requirements. TMPs will be prepared and implemented in accordance with the approved EPRs, for each area, setting out specific traffic management activities and legacy roadworks. Generally, temporary traffic management will involve signs, workers and possible signage line marking adjustments. Legacy roadworks will generally involve the re-surfacing of road, kerb and channels, road works, pedestrian/cycle crossings, and hard and soft landscaping.

There are also a series of changes to the approved Project Land related to surface road works. These are described in Section 1.2.4.

1.2.1 Parkville Station to CBD North Station

The design and construction changes to the approved Project Land at Parkville Station and between Parkville Station and CBD North Station relates to changes to the rail tunnel alignment and additional underground support structures.

Also as a result of these changes, two properties will be removed from the approved Project Land. They are 212 Berkeley Street, Carlton and 214 Berkeley Street, Carlton.

Another pedestrian adit will be required to provide an emergency egress from the tunnel to City Square. This will sit under Melbourne Town Hall footprint and the footpath at the corner of Collins Street and Swanston Street.

Construction adit A construction adit extending diagonally south from Flinders Lane towards Swanston Street, under the north western corner of St.Paul’s Cathedral.

Flinders Street Station platform works

The CYP design changes at Flinders Street Station will require an extension to the approved Project Land to include the middle section of Flinders Street Station Platforms.

Improvements will occur at Degraves Street Underpass/Campbell Arcade.

1.2.4 Additional road surface works

In addition to CYP modifications to the tunnel and station design, there is a requirement for additional roads to be added to the Project Land. This will be for construction purposes and legacy road works as follows:

• Construction purposes will namely result in road management activity such as temporary traffic management measures including signage, line marking and small kerb and channel adjustments.

• Legacy road works including road adjustments and resurfacing, tram works and pedestrian and cycle crossings.

2 Methodology

2.1 Environmental Risk Assessment

As part of the EES and PSA processes undertaken in 2016, MMRA completed a detailed environmental risk assessment (ERA) based on the Concept Design. Through this process an approved set of Environmental Performance Requirements (EPRs) were defined. The EPRs define the project-wide environmental outcomes that must be achieved during design, construction and operation of Melbourne Metro, (regardless of the design solutions adopted). As stated previously, CYP has proposed enhancements and changes to the Concept Design, and as a consequence, have undertaken an updated desktop environmental risk assessment to determine the impacts of the proposed changes on the required additional Project Land.

CYP have continued to apply a robust and transparent environmental risk assessment process to the project, based on the requirements of Risk Management Standards AS/NZS ISO 31000:2009, as depicted in Figure 19 below. ISO 31000:2009 provides principles and generic guidelines on risk management and represents a standardised risk management approach. It provides a structured approach for the risk assessment and is widely used for EESs and EIAs.

The environmental risk assessment process initially involved the definition of the context and scope of the additional Project Land required for the additional works. This entailed the preparation of an updated Project Description for buildings and works located outside of the approved Project Land. Following this, an initial environmental risk screening using the EPRs was undertaken. The approach followed by CYP involved the application of the EPRs as an assessment tool, an approach that accords with the framework established during the EES and PSA processes for the Project.

FIGURE 19: RISK ASSESSMENT PROCESS

The initial historic cultural heritage assessment undertaken by ALA confirmed an overall low to medium risk associated with the proposed changes and the impact on identified historical cultural heritage. Risk pathways associated with the modified rail tunnel alignment and additional underground support structures along Swanston Street are essentially no different to the tunnel section previously assessed. Similarly, those pathways associated with additional temporary and legacy roadworks are not dissimilar to impacts previously assessed, being largely confined to existing roads, are generally of low risk.

Based on the risks identified, analysed and evaluated as part of this environmental risk assessment, the need for detailed impact assessment for historic cultural heritage was identified.

2.2 Impact Assessment

The previous historical heritage impact assessment based on the Concept Design, Melbourne Metro Rail Project: Historical Heritage Impact Assessment (20 April 2016), was undertaken by Lovell Chen and sub consultants Jacobs (Australia) Pty Ltd and John Patrick Pty Ltd. This report was heavily utilised in the production of this impact assessment.

Due to the thoroughness of this assessment it was not found necessary to reiterate many of the sensitivities associated with the proposed change in Project Land. Only in those instances in CYP design where changes more extensive than simply a variation on what was previously proposed was it necessary to expand upon what was contained within the Lovell Chen assessment.

In other instances where the change in Project Land constituted only a limited variation to what was previously proposed (ie.a limited expansion in the land take required for tunnel alignments) variation on works previously assessed in the Lovell Chen assessment, that assessment and the conclusions derived were assessed in relation to the proposed change for the purposes of determining if those conclusions pertained to the proposed change.

This historical cultural heritage impact assessment was undertaken utilising the following data sources:

• Victorian Heritage Register

• Victorian Heritage Inventory

• MetroTunnel: Environmental Management Framework (March 2017)

3 Legislation and Guidelines

3.1.1 State Government Legislation

The Heritage Act 2017 regulates the protection and conservation of places and objects of heritage significance listed on the Victorian Heritage Register. It also provides for the protection or recording of all historical archaeological sites and relics, including those listed in the Victorian Heritage Inventory. Planning schemes prepared under the Planning and Environment Act 1987 contain Heritage Overlays that include sites and places of heritage significance, and where planning approval is required for any demolition, buildings and works. The proposed planning scheme amendment would address sites in Heritage Overlays. The proposed planning scheme amendment would manage sites in Heritage Overlays. Where a site is listed on the Victorian Heritage Register and is in a Heritage Overlay, the requirements of the Heritage Act 2017 overrides the requirements of the planning scheme. Where required, approvals and other consents would be sought from Heritage Victoria. Where a site is listed on the Victorian Heritage Register or Victorian Heritage Inventory, an approval would generally be required to carry out works or undertake activities (unless specifically exempted).

3.1.2 Environmental Performance Requirements As a part of the project approvals including the Ministerial Assessment, the Minister for Planning developed a series of

EPRs which have been applied to approve Project Land. The risk assessment will links risks to the relevant EPRs to define the standard of management to be achieved to manage potential impacts. If through review of the risk assessment additional or modified EPRs are required, the EPRs will be revised and re-submitted to the Minister for Planning for approval. A summary of the EPRs applicable to historical cultural heritage are outlined in Table 5 with corresponding descriptions for each. There are numerous links with the Ground Movement and Noise and Vibration EPRs and therefore this report should be read in conjunction with the Ground Movement and Noise and Vibration reports and their findings and results.

4 Impact Assessment

4.1 Overview

The Historical Cultural Heritage Impact Assessment has determined that all potential impacts to historical heritage fabric, arising as a result of the changes to the approved Project Land, can be dealt with effectively by the existing project EPR’s.

The risk assessment process has resulted in one residual risk rating of medium, this being related to the proposed pedestrian connection under St.Paul’s Cathedral. This is discussed further in Section 4.4.4. All other residual risk ratings returned a low or very low rating.

The proposed changes to Project Land as they affect historical heritage values do not constitute a significant departure from the works assessed under the EES and PSA processes. The EPRs remain relevant and applicable to the proposed changes. In the majority of cases there is no appreciable increase in direct physical impact to listed heritage places as the majority of works proposed are subsurface (rail tunnel alignment, additional underground support structures, pedestrian/construction adits) or superficial in nature (additional road surface works).

In the case of the proposed connection to Flinders Street Station this project component essentially comprises a realignment of the connection previously assessed. Rather than emerging within the public concourse on level 1 of the main station building and including the demolition of shopfronts fronting onto Flinders Street the proposed new access emerges within the subway and arcade under Flinders Street/Degraves Street. While the new connection will impact on heritage fabric in a different manner to the connection assessed under the EES and PSA processes the overall impact is relatively limited and localised and can be mitigated through adherence to the Environmental Performance Requirements. Minimisation of the impacts of these works to heritage fabric should come about as a result of further detailed design and planning work.

Impacts associated with construction vibration and ground movement could occur, however, these impacts were assessed under the EES and PSA processes in the historical cultural heritage assessment, the noise and vibration assessment as well as the ground settlement and land stability assessment. The measures to be implemented as a result of these assessments are directly relevant to and will suffice for the proposed works in the proposed changes to Project Land

Benefits and opportunities

4.2 Parkville to CBD North

4.2.1 Project Components

Changes to Project Land in this area are discussed in Section 1.2.1. These changes relate to tunnel realignment and additional ground support structures along the southern side of Grattan Street.

All changes to the approved Project Land will be subsurface with no surface impacts. Additional land required for rail tunnel alignments changes would be subject to the same impacts as per those previously assessed with the exception that a slightly wider horizontal alignment is required in places.

4.2.2 Existing Conditions

The proposed tunnel realignment at Church Street, Carlton intersects with one listed location on the Melbourne Planning Scheme Heritage Overlay, being HO1128 (Former Pitman Books building). The realignment of the tunnel at this location intersects marginally with the northwest corner of the heritage place. This is detailed in Table 8.

New project land required for additional underground support structures intersects with one listed location on the Melbourne Planning Scheme, being HO1 (Carlton Precinct). This is detailed in Table 9.

CROSS YARRA PARTNERSHIP Building Brilliance TAS-CYP-SDL-ZWD-REP-XLP-NAP-X0004 33

4.2.4 Impact Assessment

There will be no direct physical impact on listed heritage places within the Parkville to CBD North Precinct as a result of the proposed changes to Project Land. Intersections between listed heritage places and the proposed changes are minimal and will likely not result in a significant increase in the potential for impacts arising from vibration from tunnelling and construction activities over that likely to occur within the approved Project Land.

The potential impacts of construction and operational vibration and ground movement were assessed as part of the EES and PSA processes determining that the potential for impacts in this area was low and that potential impacts can be addressed by appropriate mitigation measures. In the case that damage occurs during works appropriate mitigation measures would need to be taken. Such measures may include a variation to the construction methodology and the rectification of any damage to accepted conservation standards. The potential for such impacts in relation to the proposed changes to Project Land is not considered to have increased appreciably.

4.2.5 Stakeholders

Engagement with the following stakeholders is required and or recommended for the proposed changes to the approved Project Land:

• City of Melbourne

• Heritage Victoria

MMRA, with the assistance of CYP, will be undertaking consultation with regards to GC82, as well as some consultation with Councils and key landowner. In recognition that project progress and decisions can be enhanced through dialogue with the community and relevant stakeholders, MMRA has developed core principles and goals for the planning and construction of the project, described in Table 9. CYP shares these principles and goals. Furthermore, the findings from this series of impact assessments will inform refinement of the Communication and Stakeholder Engagement Strategy.

TABLE 11: PRINCIPAL AND GOALS OF THE STAKEHOLDER AND ENGAGEMENT STRATEGY

A three phase approach has been developed. Phase 1 – Early Engagement, Phase 2 - Engagement to support public display of draft PSA and Phase 3: Engagement post PSA. The Consultation and Summary Report provides further detail of the process and outcomes and next steps.

Phase 1: Early Engagement

Key stakeholders –government agencies / entities /precinct based

Engagement was focused on briefing key stakeholders particularly government departments and agencies, and Councils on the proposed changes to the Project Land. MMRA and CYP held stakeholder meetings to outline the PSA process and to obtain feedback leading up to submission of the draft PSA to the Minister for Planning. Where possible, MMRA and CYP used existing stakeholder meetings to discuss the PSA. Key messages were high level with the provision of information tailored to the specific needs of the stakeholder.

CYP and MMRA held meetings with each of the following stakeholder stakeholders as part of the ongoing stakeholder engagement strategy:

• City of Maribyrnong

• City of Melbourne

• City of Port Phillip

• City of Stonnington

• DELWP

• EPA

• Heritage Victoria

• Melbourne Water

Principle Goal

Effective Engagement is open, consistent, inclusive, accessible and transparent throughout planning and delivery of the project

Timely Engagement spans all stages of the project, ensuring information is provided to stakeholders as the project develop and feedback is responded to and incorporated in the project’s development

Meaningful Engagement is clear on the elements of this project that can be influenced by the community and stakeholders, how the feedback will be used and is explicitly on which elements of the project are fixed and the reason for this

No surprises Engage early to gain understanding of interests, concerns, requirements and preferred outcomes. Close the loop to determine how feedback has been considered

• Parkville Precinct Reference Group

• Public Transport Victoria (PTV)/TfV

• State Library

• Transport for Victoria (TfV)

• VicRoads.

Landowner/Tenant Engagement

Strata divestment will be required for the proposed CYP design and construction changes to Project Land. Further,

temporary occupation may also be required for the Project Land changes at 2 and 2A Chambers Street, South Yarra, for the purposes of the Rail Infrastructure Alliance (RIA), which is yet to be appointed.

MMRA commenced early engagement with the impacted property owners and tenants as part of PSA GC82 and will continue to do so throughout the PSA process.

Letters were sent to landowners and tenants about the proposed changes to Project Land in PSA GC82. The letters outlined the impact to their property, the planning process, how to be involved and how to contact the project for assistance or support.

MMRA and CYP held meetings with each of the following stakeholders as part of the ongoing stakeholder engagement strategy:

• Capitol Theatre

• Federation Square

• MATC

• Melbourne Central

• Manchester Unity

• QV Building

• RMIT University

• University of Melbourne.

Road Surface Works

A number of roads will be included in the draft PSA to enable construction management and some legacy roadworks. Engagement with stakeholders will occur before these permanent changes are undertaken. The nature of the road surface works and the broad timelines (where available) was provided in letters to relevant stakeholders.

Phase 2: Engagement to support public display of draft PSA

The PSA will be on display for 30 calendar days with the following proposed communications tools.

Targeted Letters

Information packs were provided to landowners and tenants, tailored to whether the proposed impact on the property is as follows:

• newly within the Project Land

• newly within the DDO

• an increase in the Project Land

• an increase in the DDO

• adjacent to the road surface works

Strata divestment and DDO-related change information packs included:

• Letters to landowners advising of the proposed changes to the PSA and potential strata divestment/ a potential

Design and Development Overlay (DDO) on their property • Maps relevant to the property • Invitation to provide feedback online or contact the project team

• The information packs will outline the time frames for the PSA process, opportunity to provide feedback, the strata divestment process (if relevant) and address any immediate questions.

The draft PSA and supporting documents will be published on the Metro Tunnel website for 30 calendar days. An online feedback form will also be made available for the duration of the draft PSA public display period for landowners and tenants to provide feedback on the PSA process and potential impacts on their property. These comments will be responded to, as outlined in Phase 3 of the consultation process. A consultation summary report will be produced to support formal submission of draft Amendment GC82.

Page 39: HISTORICAL CULTURAL HERITAGE IMPACT ASSESSMENT

CROSS YARRA PARTNERSHIP Building Brilliance TAS-CYP-SDL-ZWD-REP-XLP-NAP-X0004 35

Phase 3: Engagement post PSA

CYP will provide a response and update on the issues raised to prescribed stakeholders, key stakeholders, Reference Groups, and the community. Prescribed stakeholders will receive a response on their feedback including through comprehensive briefings.

Key stakeholders will be responded to formally in writing, and in stakeholder meetings. CYP will include presentations on the feedback received to the Parkville Precinct Reference Group and Community Reference Groups. Organisations and members of the community who provide feedback either online through the survey or in writing will be responded to, where email or address details are provided.

In accordance with the existing approved Environmental Performance Requirements and the project’s contractual Project Scope & Technical Requirements, further detailed technical assessments are being undertaken including of building and asset condition, ground movement, groundwater, noise and vibration, and Electro Magnetic Interference (EMI). These assessments variously involve stakeholder consultation, and are used to inform design and construction of the project

4.2.6 Environmental Performance Requirements

4.3.4 Impact Assessment

There will be no direct physical impact on listed heritage places within the CBD North Precinct as a result of the proposed changes to Project Land. While there are numerous intersections between listed heritage places and the proposed changes to Project Land all such intersections will occur at depth and will predominantly only entail limited incursion within the curtilages of registered heritage places.

The potential impacts of construction and operational vibration and ground movement were assessed as part of the EES and PSA processes determined that the potential for impacts in this area was low and that potential impacts can be addressed by appropriate mitigation measures. In the case that damage occurs during works appropriate mitigation measures would need to be taken. Such measures may include a variation to the construction methodology and the rectification of any damage to accepted conservation standards. The potential for such impacts in relation to the proposed changes to Project Land is not considered to have increased appreciably subject to relevant technical specialist investigation

The proposed changes to Project Land do not represent a risk pathway with regards to archaeological places and heritage places listed on the Victorian Heritage Inventory. In relation to heritage places listed on the Victorian Heritage Register and or Planning Scheme Heritage Overlays the proposed changes will not results in appreciable changes in the potential for impacts arising from vibration from tunnelling and construction activities over those assessed the EES and PSA processes for existing Project Land.

4.3.5 Stakeholders

Please refer to Section 4.2.5 Stakeholder.

4.3.6 Environmental Performance Requirements

CH24 1. Prior to commencement of main works, consider the construction noise and vibration pre-construction surveys and review the ground movement plan required by EPR GM3.On this basis, identify heritage places that may be vulnerable to damage from construction and identify appropriate mitigation measures to prevent damage to heritage places.

6. Prior to the commencement of main works:

a) Conduct pre‐construction condition surveys of heritage places identified as potentially being vulnerable to damage to record structural condition and structural integrity.

b) Implement the identified mitigation measures to prevent damage to heritage places in consultation with Heritage Victoria and the relevant local council (as applicable).

c) Conduct vibration monitoring at the heritage places that may be vulnerable to damage to assess the actual impacts from construction works.

7. If the vibration monitoring demonstrates that a heritage place has been, or may be, damaged as a result of vibration, ground vibration must be reduced until the risk of vibration related damage is assessed as acceptable.

Construction techniques must also seek to limit, as far as practicable, ground movement to avoid causing damage to heritage places, (see also EPRs GM3, GM4, GM5, GM6, NV4, NV8 and NV2).

4.4 CBD South Station

4.4.1 Project Components

Changes to the approved Project Land at CBD South Station comprise realignments of tunnels along both the western and eastern boundaries of the Project Land and additional ground support structures along both sides of Swanston Street. These changes to Project Land will be subsurface with no ground level impacts.

Additional pedestrian and construction adits are proposed at the northeast corner of Collins Street and Swanston Street and the southeast corner of Flinders Lane and Swanston Streets. These changes to Project Land will be subsurface with no surface impacts.

There will be surface impacts at Degraves Street Underpass and Flinders Street Station. This is due to the insertion of lifts mid-platform at Flinders Street Station and improvement works to be carried in Degraves Street Underpass.

4.4.2 Existing Conditions

Multiple registered heritage places intersect with the proposed changes to the approved Project Land at CBD Station South associated with the tunnel realignment, additional underground support structures and pedestrian and construction adits.

4.4.4 Impact Assessment

There will be no direct physical impact on listed heritage places within the CBD South Precinct as a result of the proposed changes to Project Land in relation to the rail tunnel alignment or additional underground support structures. While there are numerous intersections between listed heritage places and the proposed changes to Project Land all such intersection will occur at depth and will predominantly only entail limited subsurface incursions within the curtilages of registered heritage places. These changes to Project Land do not represent a risk pathway with regards to archaeological places and heritage places listed on the Victorian Heritage Inventory. In relation to heritage places listed on the Victorian Heritage Register and or Planning Scheme Heritage Overlays the proposed changes will not result in appreciable changes in the potential for impacts arising from vibration from tunnelling and construction activities over those assessed under the existing EES and PSA processes for approved Project Land.

Flinders Street Station connection and platform works

Proposed changes to Project Land comprise of improvements to the Campbell Arcade and Degraves Street Underpass The Degraves Street/Campbell Arcade subway is part of the registered curtilage of Flinders Street Station (VHR 1083). There will also be the installation of DDA compliant lifts, mid-platform at Flinders Street Station.

The CMP for this place, Flinders Street Station Conservation Management Plan (Lovell Chen, 2012), notes that among numerous other features the ‘structure and original internal fabric of the Central (Degraves Street) subway’ constitutes an element of primary significance of the place, along with the ‘original fabric of the stairs and entry ramps to platforms’ and ‘original platform direction and other signage incorporated into tiled walls’. In relation to Campbell Arcade the VHR citation report also notes that the ‘structure and original internal fabric of Campbell Arcade including at its extant and closed exits’ is similarly to be considered an element of primary significance.

The CMP also notes elements of significant fabric which should be sought to be conserved and or restored and reconstructed. Such fabric includes the polished black granite columns, chromed steel shopfronts within Campbell Arcade and all original salmon pink and white tiling both the arcade and the subway.

The works at Degraves Street Underpass and Campbell Arcade will include:

o unblocking and cleaning drains in Degraves Street Underpass and repairing/refurbishing any critical water pumps to ensure Degraves Street Underpass meets applicable watertightness Codes of Practice.

o removal of any loose or cracked wall tiles

o retention of existing finishes where practicable with appropriate cleaning and localised repairs

o installation of new finishes using materials similar to those initially used

Overall, the impact of the new works at Campbell Arcade would be modest in scale and can be dealt with at the detailed design phase. Furthermore, additional permit (s) required under the Heritage Act 2017 any works in the Arcade.

In addition to these works new lift connections to the station platforms are also proposed. Construction of these will involve demolition works as well as platform level changes including the addition of lift entry/exit points, potential temporary removal of platform canopies. As such there will be some loss of significant fabric (original tiling) within the stations in order to accommodate lift entrances. Temporary removal of platform canopies, if required, can be managed carefully throughout the detailed design and construction phase. Heritage Victoria have been consulted throughout the process and are supportive of modern elements being incorporated into the heritage fabric of Flinders Street Station. The design is still being refined, with the lift and overruns installation aiming to have minimal impact on the canopies. The lift manufacturers have been part of the discussion to ensure that the design response is sympathetic to the heritage fabric while ensuring DDA compliance. Similarly, potential impacts to visual amenity by the addition of new structures situated in the middle of the station platforms at platform level can be managed in the detailed design process.

In all instances the design process will be informed by heritage advice in order to limit and minimise any adverse impacts to fabric and the overall visual experience of the station. Furthermore, the requirement in the Incorporated Document to provide a Development Plan will support the process and ensure stakeholders and the public are appropriately consulted. Specifically, the EPRs CH1, CH2, CH3, CH6 would ensure minimal impact and protection of heritage value, where possible. CH5 ensures any works that requires the heritage fabric to be dismantled has a methodology undertaken in accordance with Australia ICOMOS Burra Charter 2013 and Heritage Victoria. CH10 and CH23 would ensure development is responsive to the place in terms of design. Finally, additional permit (s) required under the Heritage Act 2017 any works in the Arcade.

Pedestrian/Construction adit

The proposed changes to Project Land in relation to this project component considers a pedestrian/construction adit connection between City Square and CBD South Station, extending under the northwest corner of St Paul’s Cathedral and under land associated with this structure. The EES and PSA processes considered a similar connection to Federation Square under land associated with the cathedral and determined no physical impact on the significant fabric of the cathedral. Similarly, the current proposed change to Project Land will not result in any direct physical impact on fabric.

Page 54: HISTORICAL CULTURAL HERITAGE IMPACT ASSESSMENT

CROSS YARRA PARTNERSHIP Building Brilliance TAS-CYP-SDL-ZWD-REP-XLP-NAP-X0004 50

The potential impacts of construction and operational vibration and ground movement were assessed as part of the EES and PSA processes also, and determined that the potential for impacts to heritage fabric in this area was low and that potential impacts can be addressed by appropriate mitigation measures. In the case that damage occurs during works appropriate mitigation measures would need to be taken. Such measures may include a variation to the construction methodology and the rectification of any damage to accepted conservation standards.

Preliminary ground movement modelling was undertaken by CYP in relation potential impacts to St Paul’s Cathedral from the pedestrian and construction adits. These preliminary results indicate that the modelled displacement falls into the ‘very slight’ damage category, defined as typical crack widths of up to 1mm.

In addition, preliminary ground movement modelling was undertaken by CYP in relation to potential impacts to Melbourne Town Hall. These preliminary results indicate that the modelled displacement falls into the ‘very slight’ damage category for one building damage line along the western boundary. However, the building only extends along part of this boundary, with another building damage line falling into the ‘slight’ damage category, defined as crack widths up to 5mm. Based on the Phase 2 damage assessment, the residual risk is assessed as Moderate consequence, Unlikely likelihood, giving a ground movement risk of Low.

Overall, EPRs CH1, CH2, CH3, CH6 would ensure minimal impact and protection of heritage value, where possible. As the works are at strata (underground), CH24 adequately ensures construction noise and vibration and ground movement are taken into consideration throughout works. Construction techniques will seek to limit the damage to heritage places. GM3, GM4, GM5, GM6, NV4, NV8 and NV2 further support a conducive construction methodology that would manage impacts to the heritage fabric.

Prior to commencement of main works, consider the construction noise and vibration pre-construction surveys and review the ground movement plan required by EPR GM3.On this basis, identify heritage places that may be vulnerable to damage from construction and identify appropriate mitigation measures to prevent damage to heritage places.

1. Prior to the commencement of main works:

a) Conduct pre‐construction condition surveys of heritage places identified as potentially

being vulnerable to damage to record structural condition and structural integrity.

b) Implement the identified mitigation measures to prevent damage to heritage places in consultation with Heritage Victoria and the relevant local council (as applicable).

c) Conduct vibration monitoring at the heritage places that may be vulnerable to damage to assess the actual impacts from construction works.

If the vibration monitoring demonstrates that a heritage place has been, or may be, damaged as a result of vibration, ground vibration must be reduced until the risk of vibration related damage is assessed as acceptable.

Construction techniques must also seek to limit, as far as practicable, ground movement to avoid causing damage to heritage places, (see also EPRs GM3, GM4, GM5, GM6, NV4, NV8 and NV2).

4.5.4 Impact Assessment

While the proposed changes to Project Land for additional road surface works intersect with the curtilages of number of Victorian Heritage Register Places the proposed works are surficial and superficial in nature and will not result in any material impacts to these places. Royal Parade will not be impacted by legacy road surface works as there will be no trees removed that as a result of the bus stop works, road adjustments and resurfacing (see Figure 20).

5 Conclusion The proposed changes to the approved Project Land as they affect historical heritage values do not on the whole constitute a significant departure from the works previously assessed. The changes generally represent a realignment of works of a similar nature assessed as part of the EES and PSA processes. EPRs remain relevant and applicable to the proposed changes. In the majority of cases, there is no appreciable increase in direct physical impact to listed heritage places as the majority of works proposed are subsurface (rail tunnel alignment, additional underground support structures, pedestrian/construction adits) or superficial in nature (additional road surface works)..

The principal exception to this are the proposed works at Flinders Street Station which will include impacts to the Campbell Arcade and Degraves Street Underpass through the works and impacts to station platforms through the construction of lift access to platform level. These changes will have impacts on significant fabric elements of the station, however, these can be managed through heritage input at the detailed design phase. It is also worth noting that heritage permits will be required as relevant under the Heritage Act 2017, for example at Flinders Street Station.

Impacts associated with construction vibration and ground movement could occur, however, these impacts were assessed as part of the EES and PSA processes in the historical cultural heritage assessment as well as the noise and vibration assessment and the ground settlement and land stability assessment. Ongoing assessment around these is occurring, particularly in relation to the Melbourne Town Hall and St Paul’s Cathedral with an initial view that the impacts are considered acceptable and able to be managed through the current EPRs. The EPRs set a range of standards and ensure that mitigation and management options are identified and implemented, as appropriate. The measures to be implemented will suffice for the proposed works located within the additional Project Land
