HISTORICAL ARCHAEOLOGICAL ASSESSMENT & RESEARCH DESIGN APPENDIX H Sydney Metro City & Southwest Chatswood to Sydenham - ARD Sydney Metro City & Southwest Chatswood to Sydenham Historical Archaeological Assessment & Research Design Report to Jacobs / Arcadis / RPS FINAL_14102016 October 2016 Page i Sydney Metro City & Southwest Chatswood to Sydenham - ARD EXECUTIVE SUMMARY Project Background The proposed Sydney Metro City & Southwest Chatswood to Sydenham project (the project) is the subject of this Historical Archaeological Assessment and Research Design (ARD). The project would involve construction and operation of an underground rail line, about 15.5 kilometres long, and new stations between Chatswood and Sydenham. The Environmental Impact Statement (EIS) identified the potential for archaeological constraints and the need for the preparation of a historical ARD (mitigation measure NAH2) at all surface construction sites except Artarmon traction substation and Marrickville dive site (southern). This ARD has been prepared to comply with mitigation measure NAH2. The ten sites that are considered in this report are: x Chatswood dive site (northern) x Crows Nest Station x Victoria Cross Station x Blues Point temporary site x Barangaroo Station x Martin Place Station x Pitt Street Station x Central Station x Waterloo Station x Power Supply Routes – various locations near the metro rail line route. Archaeological Management The station and construction sites have been divided into archaeological management zones based on archaeological potential and construction impacts as submitted with the EIS. Archaeological management zone mapping provided in Section 13.3 is based on a ‘traffic light’ coding: x Red (Zone 1): Direct impact to significant archaeology. Archaeological investigation required prior to any construction impacts (bulk excavation etc.) x Amber (Zone 2): Potential impact to significant archaeology. Prepare Work Stage Specific Archaeological Method Statement (AMS) once construction methodology and impacts are known. Archaeological investigation is likely required x Green (Zone 3): Unlikely to contain significant archaeology. Construction to proceed with unexpected finds procedure as nil-low potential for significant archaeological remains. Page ii Sydney Metro City & Southwest Chatswood to Sydenham - ARD Archaeological Mitigation The following table presents a summary of the archaeological management and impact mitigation for the project. The summary is based on detailed analysis presented in this report.
