The assessment found that it was unlikely for either archaeological or cultural sites to exist within or in relation to the proposed Russell Extension corridor. The proposed works would therefore not impact upon places of Aboriginal heritage values along this alignment. There are no further requirements for assessment of Aboriginal heritage values for the proposed Russell Extension Project. Adequate environmental management measures would be developed and implemented during the construction of the Project to manage potential impacts to any unexpected Aboriginal heritage item uncovered during construction. Non-Aboriginal heritage and historical archaeology The Project has the potential to have an impact on listed and nominated heritage places and objects along its route. Generally, this would comprise potential impacts on the setting of heritage places and objects, rather than direct impacts on their fabric. These impacts could arise from placing new elements, such as substations, within significant settings of heritage places, or by the stops and shelters or associated infrastructure blocking important views to heritage places along London Circuit, Constitution Avenue or Russell Drive. Overall, the approach taken to the design and development of the Russell Extension Project, based on a detailed understanding of the heritage values of the heritage places along the Project alignment, has contributed positively to an appropriate approach which minimise or avoids heritage impacts. The approach has included minimising the visual presence of the Project through the use of wire-free technology; at-grade embedded tracks within the Northbourne Avenue, London Circuit, Constitution Avenue and Russell Drive roadways; and lightweight steel-framed and glazed stops. This approach means that the light rail would not appear as an intrusion in the significant landscape of the Parliamentary Triangle, and other heritage elements such as the Australian War Memorial and Memorial Parade. Similarly, while the Russell Terminus does not respond to the symmetrical design of the Russell Precinct Heritage Area, it has been sited outside key views to and from the precinct from Kings Avenue and designed to be recessive in scale and materials to the buildings of the precinct. Nevertheless, the terminus would have a minor impact on the urban design qualities of the Russell Precinct Heritage Area. Future development of Russell as set out in NCP Amendment 60 – Constitution Avenue would assist in further mitigating this minor impact. The Project would require the relocation of one of the custom-designed street light poles located along Anzac Parade. In order to mitigate this impact, the opposite street light pole would also be relocated (up to three metres to the south) to retain the symmetry of these poles. Minor visual impacts from construction works and hoardings in the Australian War Memorial and Memorial Parade would be fully mitigated on completion of construction through the removal of any hoardings. No heritage places and objects registered on or nominated to the ACT Heritage Register are likely to be subject to direct physical impacts as a result of the proposal. There would also be minimal to no visual impacts on heritage places and objects on either side of the Russell extension corridor. Additionally, with respect to potential impacts to historical archaeological values, the route is also considered to have a low likelihood for the existence of non-Aboriginal historical archaeological remains. Therefore the Russell Extension Project is considered unlikely to impact upon non-Aboriginal historical archaeological remains. 44 2207509A-ENV-REP-008 RevB | Parsons Brinckerhoff Capital Metro Authority Capital Metro Russell Extension Project - Preliminary Environmental Assessment A detailed heritage impact assessment would be undertaken as part of any future environmental assessment of the Russell Extension Project to future detail and assess the potential impacts and propose mitigation measures to existing non-Aboriginal heritage items along the Russell Extension Project alignment. Further discussion regarding the potential impacts listed/nominated heritage places and objects is provided in Chapter 6 of the Heritage Impact Assessment (GML Heritage, 2015) attached as Appendix A of this report. 5.3 Noise and vibration A preliminary Noise and Vibration Impact Assessment of the Russell Project was undertaken by SLR Consulting Pty Ltd (SLR) in June 2015 with the aim of identifying potential noise and vibration impacts as a result of the Russell Extension Project. A summary is provided below with the full report provided as Appendix B – Capital Metro – Russell Extension: Preliminary Noise and Vibration Impact Assessment (SLR, 2015). 5.3.1 Existing environment The Russell Extension Project would be located in urban environments of the ACT and relatively close to suburban parts of Reid and Campbell. The extension would sit primarily within established road transportation corridors, including the revised road network associated with the Constitution Avenue and Anzac Parade structure plan identified in Appendix T8 of the National Capital Plan. The Russell Extension alignment would pass through, or adjacent to: Canberra City Parkes Reid Campbell Russell. The existing ambient noise environment surrounding the Russell Extension alignment is variable, with road traffic noise the primary influence. In addition to road traffic, the ambient noise environment within the CBD is influenced by general urban noise from mechanical plant and pedestrian activities. Existing noise levels are generally higher in the Canberra Civic centre than in the surrounding suburbs. During the evening and night- time in the suburban areas the ambient noise decreases in locations where road traffic decreases from daytime volumes. Noise and vibrations sensitive receptors A series of existing noise and vibrations sensitive receptors have been identified along the Russell Extension Project alignment. These include residential properties, education institutions (such as the Canberra Institute of Technology), commercial properties, places of worship (such as the Canberra City Uniting Church and St Johns the Baptist Church and Rectory) and other sites (such as the Canberra Museum and Gallery, Canberra Theatre Centre and the Canberra Civic Library). Initial consideration of the identified sensitive receivers has noted that residential premises and the Canberra Theatre Centre are likely to be the most sensitive receivers along the Russell Extension Project alignment. The proposal area has been divided into two main precinct areas. These precincts reflect the land uses adjacent to the proposal and are detailed in Table 5.3, together with corresponding Noise Catchment (NCs) that have been used to represent each of the precincts. The location of the NCs is indicated on the figures provided in the Preliminary Noise and Vibration Impact Assessment (SLR, 2015) attached as Appendix B.
