CHATSWOOD TO SYDENHAM ENVIRONMENTAL IMPACT STATEMENT MAY 2016 TECHNICAL PAPER 4: NON-ABORIGINAL HERITAGE IMPACT ASSESSMENT Sydney Metro City & Southwest – Chatswood to Sydenham Non-Aboriginal Heritage – Heritage Impact Assessment Sydney Metro City & Southwest – Chatswood to Sydenham Technical Paper 4 Non-Aboriginal Heritage Impact Assessment Report to Jacobs / Arcadis / RPS May 2016 Page i Sydney Metro City & Southwest – Chatswood to Sydenham Non-Aboriginal Heritage – Heritage Impact Assessment EXECUTIVE SUMMARY Project overview Sydney Metro is a new standalone rail network identified in Sydney’s Rail Future. The Sydney Metro network consists of Sydney Metro City & Southwest and Sydney Metro Northwest. The proposed Sydney Metro City & Southwest comprises two core components: • The Chatswood to Sydenham project (the project), the subject of this technical paper, would involve construction and operation of an underground rail line between Chatswood and Sydenham • The Sydenham to Bankstown upgrade would involve the conversion of the 13.5 kilometre Bankstown line to metro standards and upgrade of existing stations between Sydenham and Bankstown. The Sydenham to Bankstown upgrade will be subject to a separate environmental impact assessment. Investigations have also commenced on a potential extension of metro rail from Bankstown to Liverpool, which could cut travel times to the Sydney CBD by up to 15 minutes and reduce crowding on the existing T1 Western Line and T2 South Line. The Sydney Metro Chatswood to Sydenham project (the project) involves the construction and operation of a metro rail line. The project would be mainly located underground in twin tunnels extending from Chatswood on Sydney’s north shore, crossing under Sydney Harbour, and continue to Sydenham. The key components of the project would include: • About 15.5 kilometres of twin rail tunnels (that is, two tunnels located side-by-side) between Mowbray Road, Chatswood and north of Sydenham Station (near Bedwin Road, Marrickville) • Realignment of the existing T1 North Shore Line surface track within the existing rail corridor between Chatswood Station and in the vicinity of Brand Street, Artarmon, including a new bridge for a section of the ‘down’ (northbound) track to pass over the proposed northern dive structure • About 250 metres of aboveground metro tracks between Chatswood Station and the Chatswood dive structure • A dive structure (about 400 metres long) and tunnel portal south of Chatswood Station and north of Mowbray Road, Chatswood (the Chatswood dive structure) • A substation (for traction power supply) at Artarmon • Metro stations at Crows Nest, Victoria Cross, Barangaroo, Martin Place, Pitt Street and Waterloo; and new underground platforms at Central Station • A dive structure (about 400 metres long) and tunnel portal between Sydenham Station and Bedwin Road, Marrickville (the Marrickville dive structure) • A services facility (for traction power supply and an operational water treatment plant) adjacent to the Marrickville dive structure. The project would also include a number of ancillary components, including new overhead wiring and alterations to existing overhead wiring, signalling, access tracks / paths, rail corridor fencing, noise walls, fresh air ventilation equipment, temporary and permanent alterations to the road network, facilities for pedestrians, and other construction related works. Page ii Sydney Metro City & Southwest – Chatswood to Sydenham Non-Aboriginal Heritage – Heritage Impact Assessment Approach to Non-Aboriginal heritage assessment Artefact Heritage has been engaged to prepare a non-Aboriginal heritage assessment by the Jacobs / Arcadis / RPS team for inclusion in the EIS for the project. This technical paper considers the construction and operational impacts on listed heritage items and potential archaeological resources within the study area and includes: • Identification of items and areas of heritage significance that would be materially affected by the project during construction and operation, by field survey and research, including any buildings, works, relics, views, or places of heritage significance • Consideration of the potential impacts on the values, settings and integrity of heritage areas and items and archaeological resources located within the project area. including items both above and below ground and, where such potential exists, the likely significance of those impacts • An outline of the proposed mitigation and management measures (including measures to avoid significant impacts and an evaluation of the effectiveness of the mitigation measures) in accordance with relevant best practice guidelines. Overview of potential impacts The project has potential to have a moderate to major impact on 20 listed heritage items (being five state heritage listed sites and 15 sites of local heritage significance). The 20 listed heritage items are described, from north to south, in the table below. Heritage item Project site Significance Description of potential impact Direct impact: Major (complete Shop at 187 Miller Street Victoria Cross station Local demolition) Victoria Cross Station Direct impact: Moderate (removal and North Sydney bus stops Blues Point temporary Local relocation) site Direct impact: Minor to moderate (shaft excavation) Blues Point Waterfront Blues Point temporary Archaeological impact – minor to Local Group site major (shaft excavation) Temporarily indirect: Minor to moderate (views and vistas) Direct impact: Minor to moderate (shaft excavation) McMahons Point South Blues Point temporary Archaeological impact – minor to Heritage Conservation Local site major (shaft excavation) Area Temporarily indirect: Minor to moderate (views and vistas) Indirect impact: Minor to moderate Millers Point & Dawes (views and vistas) Barangaroo station State Point Village Precinct Archaeological impact – major (station box excavation) Commonwealth Bank of Indirect impact: Moderate (views and Australia including Martin Place station State vistas) interior Page iii Sydney Metro City & Southwest – Chatswood to Sydenham Non-Aboriginal Heritage – Heritage Impact Assessment Heritage item Project site Significance Description of potential impact Flat building including Direct impact: Major (complete Martin Place station Local interior demolition) Direct impact: moderate (excavation) Archaeological impact –major Martin Place Martin Place station Local (excavation) Indirect impact: Minor - moderate (views and vistas) Martin Place Railway Martin Place station Local Direct impact: Moderate (interchange) Station Indirect impact: Minor to moderate Masonic Club Pitt Street station Local (views and vistas) Criterion Hotel including Indirect impact: Minor to moderate Pitt Street station Local interior (views and vistas) Former “Speedwell Indirect impact: Minor to moderate House” including Pitt Street station Local (views and vistas) interiors Indirect impact: Minor to moderate Edinburgh Castle Hotel Pitt Street station Local (views and vistas) Former Sydney Water Indirect impact: Moderate to major Pitt Street station State Building (views and vistas) Direct physical impacts: Moderate to major (excavation, demolition, Sydney Terminal and construction, vibration) Central Railway Stations Central Station State Archaeological impact –major group (excavation) Indirect impact: Moderate to major (views and vistas) Terrace Group including Indirect impact: Moderate (views and interior (99-105 Regent Central Station Local vistas) Street) Former Crown Hotel Indirect impact: Moderate (views and Central Station Local including interior vistas) Indirect impact: Moderate to major Mortuary Railway Station Central Station State (views and vistas) Former Co-Masonic Indirect impact: Moderate to major Central Station Local Temple including interior (views and vistas) Chippendale Heritage Indirect impact: Moderate (views and Central Station Local Conservation Area vistas) Page iv Sydney Metro City & Southwest – Chatswood to Sydenham Non-Aboriginal Heritage – Heritage Impact Assessment Nine sites are identified as having non-Aboriginal archaeological potential. Ground disturbance and excavation at these sites could impact on archaeological resources. The potential archaeological sites are: Potential Assessment of Project site Archaeological potential significance potential impact Study area has moderate potential to Chatswood Dive Site contain archaeological remains associated Local Minor to moderate (northern) with mid to late 19th century residential and commercial development. Study area has low potential to contain archaeological remains associated with mid Crows Nest station Local Major to late 19th century residential and commercial development. Study area has low to moderate potential to contain archaeological remains associated Victoria Cross station Local Minor to major with mid to late 19th century residential and commercial development. Study area has low to moderate potential to contain archaeological evidence of pre- Blues Point temporary 1850s foreshore development, mid to late Local-State Minor to major site 19th century shipbuilding industry and mid to late 19th century development of the site.
