Executive Summary Executive Summary Overview and need Mass transit services are a fundamental part of a growing international city. Public transport improvements between Sydney’s three cities – the Eastern Harbour City, Central River City and Western Parkland City – are part of Transport for NSW’s Future Transport Strategy 2056 (Transport for NSW, 2018a). Sydney Metro West is a critical step in the delivery of Future Transport Strategy 2056. It would provide a fast, reliable and frequent rail service between Greater Parramatta and the Sydney CBD and would: Relieve the congested T1 Western Line, T9 Northern Line (previously T1 Northern Line) and T2 Inner West Line Provide travel time savings for customers in Western Sydney and along the Greater Parramatta to Sydney CBD corridor Reduce station crowding at some stations Provide rail transport to areas where it is currently not available Connect Greater Parramatta and the Sydney CBD to support the vision for a metropolis of three cities Support delivery of the ‘30-minute city’ as identified in Future Transport Strategy 2056 Reinforce the role of Greater Parramatta as the Central River City Improve connectivity to major attractions and key precincts located along the corridor, including Sydney Olympic Park and The Bays Precinct Support urban renewal and increased housing supply Increase accessibility across Sydney and provide customers with a new world-class metro service. Sydney Metro West Sydney Metro (as ‘the proponent’) is seeking planning approvals as follows: Approval for the whole Sydney Metro West at concept level (this application) Approval of Stage 1. Stage 1 would involve the major civil construction work between Westmead and The Bays Precinct (this application) Future stage(s) would include the remaining major civil construction work from The Bays Precinct to the Sydney CBD, rail systems fit-out, station fit-out, aboveground building construction, and operation of the metro line (future application(s)). Sydney Metro West Concept Sydney Metro West (the Concept) would involve construction and operation of a metro rail line around 24 kilometres long between Westmead and the Sydney CBD. Key components are expected to include: About 24 kilometres of twin tunnels between Westmead and the Sydney CBD New metro stations at Westmead, Parramatta, Sydney Olympic Park, North Strathfield, Burwood North, Five Dock, The Bays and Sydney CBD. Potential stations at Rydalmere and Pyrmont are also under investigation A turn-up-and-go metro service operating early morning to late at night, between Westmead and Sydney CBD Pedestrian links and connections to other modes of transport (such as the existing suburban rail network and other parts of the metro network), and surrounding land uses Sydney Metro West Scoping Report | Westmead to The Bays and Sydney CBD i Executive Summary Modification to existing suburban stations and associated rail infrastructure (such as overhead wiring, signalling, access tracks/paths and rail corridor fencing) at Westmead and North Strathfield Services within each of the metro stations, including mechanical and fresh air ventilation equipment and electrical power substations to supply power for operation Services facilities at Rosehill (within the Clyde stabling and maintenance facility construction site), Silverwater and one between Five Dock and The Bays Precinct for fresh air ventilation and emergency evacuation A stabling and maintenance facility at Clyde, including associated aboveground and belowground tracks to connect to the mainline tunnels Alterations to pedestrian and traffic arrangements, cycling and public transport (e.g. bus) infrastructure around the new stations Ancillary facilities to support construction. Components of the Concept are subject to further design, and changes or clarifications may be made during the ongoing design development and community consultation processes. Stage 1 Major construction between Westmead and The Bays Precinct Stage 1 would involve major civil construction work between Westmead and The Bays Precinct, including: Enabling work Tunnel excavation including tunnel support activities Station excavation for the new metro stations at Westmead, Parramatta, Sydney Olympic Park, North Strathfield, Burwood North, Five Dock and The Bays Shaft excavation for services facilities at Rosehill (within the Clyde stabling and maintenance facility construction site), Silverwater and between Five Dock and The Bays Precinct Civil work for the stabling and maintenance facility at Clyde including earthworks and structures for crossings of A’Becketts Creek and Duck Creek A concrete segment facility for use during construction located at the Clyde stabling and maintenance facility construction site Excavation of a tunnel dive structure and associated tunnels at Rosehill to support a connection between the Clyde stabling and maintenance facility and the mainline metro tunnels. Planning and assessment process Sydney Metro is seeking a declaration for Sydney Metro West to be State significant infrastructure and critical State significant infrastructure under sections 5.12(4) and 5.13 of the Environmental Planning and Assessment Act 1979 (EP&A Act), respectively. Therefore, Sydney Metro West would be subject to assessment and approval by the Minister for Planning and Public Spaces under Part 5, Division 5.2 of the EP&A Act. Purpose of this document This document supports the Sydney Metro West Concept and concurrent Stage 1 State significant infrastructure application to the Minister for Planning and Public Spaces under section 5.15 of the EP&A Act, to obtain the Secretary’s Environmental Assessment Requirements for the Concept and Stage 1 Environmental Impact Statement. ii Sydney Metro West Scoping Report | Westmead to The Bays and Sydney CBD Executive Summary Key environmental issues A preliminary environmental risk analysis has identified key environmental issues which are relevant to the assessment of the Concept and Stage 1. These are summarised in Table E-1. Table E‑1: Key environmental issues Key issues Concept Stage 1 Construction traffic and ansporttr Yes Yes Construction noise and vibration Yes Yes Non‑Aboriginal heritage Yes Yes Aboriginal heritage Yes Yes Property and land use Yes Yes Landscape character and visual amenity Yes Yes Contamination Yes Yes Social impacts and community infrastructure Yes Yes Business impacts Yes Yes Hydrology and flooding Yes Yes Cumulative impacts Yes Yes A preliminary environmental assessment of potential impacts has confirmed the above issues have the potential to result in a significant impact (without the adoption of adequate mitigation measures). Detailed assessment of these issues and the other environmental issues identified would be carried out as part of an Environmental Impact Statement. While not identified at this stage as key issues, other issues that will be included in the assessment of the Concept and Stage 1 are: Operational traffic and transport (Concept only) Operational noise and vibration (Concept only) Groundwater and geology Soils and water quality Biodiversity Air quality Greenhouse gas Climate change adaptation Waste management and resource use Hazard and risk. Sydney Metro West Scoping Report | Westmead to The Bays and Sydney CBD iii Executive Summary Next steps Following receipt of the Secretary’s Environmental Assessment Requirements, Sydney Metro will prepare and publicly exhibit an Environmental Impact Statement in accordance with the requirements of Division 5.2 of the EP&A Act. The Environmental Impact Statement will include: The strategic need and justification for Sydney Metro West A description of the Concept for which approval is being sought A description of the Stage 1 components and construction activities A description of the existing environment relevant to Sydney Metro West and an assessment of potential direct and indirect impacts on key environmental issues during construction and operation A description of the existing environment relevant to Stage 1 and an assessment of potential direct and indirect impacts on key and other potential environmental issues during construction For the Concept, identification of further environmental assessment required for future stages For Stage 1, identification of measures to be implemented to avoid, minimise, manage, mitigate, offset and/or monitor potential impacts Identification and consideration of issues raised by stakeholders and the community during preparation of the Environmental Impact Statement.
