Category C: Minimal level of investigation is required as part of the assessment and approvals process. For some Category C issues, which are construction based, it was considered acceptable for investigation and management planning to be primarily undertaken after the assessment and approvals phase, prior to construction, when greater detail regarding construction activities would be available. In these instances, commitments for the management of the issue during construction would be made during the assessment and approvals process (refer to discussion in Section 8.4). The category assigned to each issue was based on both the: and severity of the potential impact (Consequence). Complexity of the mitigation measures required to manage the potential impact. The description of each category is presented in Table 6 below. Table 6 Investigation Categories Investigation category Potential consequence Complexity of mitigation A High - Potential for extensive, long term impacts, significant assets or values affected with enduring changes (including potential for benefits). Widespread community interest. Complex and detailed management measures required B Medium - Potential for moderate impacts, significant assets or values may be affected over an extended time frame with some resultant changes (including benefits). Regional community interest. Standard management measures are available that can be adopted with some tailoring C Low - Potential for short term and localised impact. Asset or values may be temporarily affected but recovery expected. Local community interest. Standard management measures are available. Routinely managed on equivalent projects In selecting a consequence category, an impact was considered to have “potential” if it has a real or not remote chance of occurring (with the application of mitigation measures). It was assumed that where applicable standard mitigation measures applied on similar past projects would be used. Results Table 7 and Table 8 present the findings of the issues screening exercise for Part A of the project (Eastern Freeway to CityLink) and Part B of the project (CityLink to the Port of Melbourne). Parts A and B of the project were split up for this exercise in order to reflect potential staging.
3.4 Potential for impacts on undocumented sites of European heritage significance Heritage places and values Yes Construction & Operation C Heritage within the indicative corridor has been well documented. Comprehensive post settlement heritage investigations would need to be undertaken during the planning process 4 Aboriginal cultural heritage 4.1 Potential impacts to areas of cultural heritage sensitivity at the Merri Creek and Royal Park environs. Cultural heritage Yes Construction & Operation B The majority of the indicative corridor is highly disturbed. Further cultural heritage investigations would be undertaken in areas of sensitivity in order to prepare a Cultural Heritage Management Plan (CHMP). 5 form, visual and landscape 5.1 Integration of project structures with surrounding urban form, local character and streetscape Urban form / places Yes Operation A Project structures (ventilation structures, portals, bridges or elevated roadways) would need to be sensitively designed using good urban design principles in order to maintain, as much as practicable, existing urban form. 5.2 Potential visual impacts of project structures (e.g. tunnel portals and elevated roadways) Visual amenity Yes Operation A Tunnel portals and elevated roadways potentially have a significant visual impact but would be sensitively designed by adopting good design urban principles to minimise to the greatest extent possible such visual impact. 5.3 Compatibility with existing and future land use Existing and future land uses Yes Operation A Project structures would need to be designed to ensure that future land uses are not unreasonably compromised.
2 Noise and vibration 2.1 from vehicles using surface roads and elevated roadways Residential amenity Yes Operation B Any changes in noise levels near residential areas would be investigated and noise attenuation measures incorporated into design. 2.2 Noise and vibration from construction activities could potentially cause short term disturbance. Residential amenity Construction C Noise and vibration from construction would be temporary and would depend on particular construction activities. Construction noise would be managed via an EMP with particular care taken when works are in proximity to sensitive receptors, consistent with EPA guidelines. 3 Post settlement heritage 3.1 Potential impact to registered heritage places through surface construction activities Heritage places and values Yes Construction & Operation C Preservation of significant heritage features as much as possible would be incorporated into the design phase as appropriate. If impacts to heritage places are expected, investigations into potential effects and mitigation opportunities would be undertaken. Victorian Heritage Register and Inventory sites located within the vicinity of the indicative corridor include: Debneys Park East (VHI), Former Burge Brothers Factory (VHR) and West Melbourne rubbish Tips (VHI)
8.6 Loss in quality and function of open space/parkland Public open Yes Operation B There are some areas of public open space along Moonee Ponds Creek and Debneys Park. Loss of open space would be avoided where possible. 8.7 Potential temporary loss of access to public open space/parkland during construction period Public open space Construction B There are some areas of public open space within the corridor including Debneys Park and Moonee Ponds Creek. Temporary loss of access to open space would be avoided where possible 8.8 Potential loss of community facilities Community facilities Construction & Operation B It is expected that as part of the design development process, loss of community facilities would be avoided. If loss of community facilities does occur, opportunities for replacement of facilities would be investigated. 8.9 Potential impact on pedestrian or bike paths during construction Community access and mobility Construction B Any existing pedestrian or bike paths that are severed would be reinstated in a suitable location. 8.10 Potential impact on public transport services during construction Community access and mobility Construction C Construction are not expected to cause significant impacts on public transport services. Any impacts would be temporary in nature and would be managed through a Traffic Management Plan. 9 Economics and business 9.1 Economic benefits from the project through improved access and mobility and reduced travel times Business viability and employment Operation A Economic benefits associated with changed connectivity at the regional level would be described.
12.2 Odour from excavation of contaminated materials Residential amenity Construction C Management of contaminated soil during construction would be controlled through comprehensive management measures in an EMP. 12.3 Potential pollution from disturbance to acid sulphate soils (ASS) Waterways / land / ecosystems Construction C Management of ASS would be controlled via comprehensive management measures within an EMP.
