The key benefits of the project are: Provide a direct link between Armadale Road and North Lake Road, bypassing congestion at Cockburn Central Station and the Cockburn Gateway shopping centre Improved access to Kwinana Freeway to and from the north Easier access to Cockburn Central Station Support residential and commercial expansion in Cockburn and Armadale Complement other significant road improvements in the Southern Metropolitan Corridor including the duplication of Armadale Road, Kwinana Freeway Northbound Widening and the Murdoch Drive Connection to Kwinana Freeway and Roe Highway The project development was undertaken by the Metropolitan Road Improvement Alliance (MRIA) formed between Main Roads Western Australia (Main Roads), CPB Contractors, Georgiou Group, WA Limestone, GHD, AECOM and BG&E. 1.2 Design Area Descriptions The project area is shown in Figure 1-1. Figure 1-1 Armadale Road to North Lake Road Structures Location Plan Metropolitan Road Improvement Alliance Page 4 of 41 Issue Date: 08/08/2018 Armadale Road to North Lake Road - Noise Assessment Report This noise report covers the following two project options only: Option 2 – Grade Separated Viaduct The works under Option 2 will include the design and construction of the following: Bridge 1733: North Lake Road over Kwinana Freeway and Mandurah Rail Line Underpass 9454: PSP loop crossing Bridge 1825: North Lake Road over Prinsep Road Extension An elevated viaduct carrying the main alignment of Armadale Road over grade separated roundabouts at Solomon Road and Tapper Drive Option 3 – Grade Separated Viaduct and Dive Structure The works under Option 3 will include the design and construction of the following: Bridge 1733: North Lake Road over Kwinana Freeway and Mandurah Rail Line Underpass 9454: PSP loop crossing Bridge 1825: North Lake Road over Prinsep Road Extension An elevated viaduct carrying the main alignment of Armadale Road over a grade separated roundabout at Tapper Drive A dive structure and trench carrying the main alignment of Armadale Road under a grade separated roundabout at Solomon Road The project also includes works on the Kwinana freeway: North facing off ramp at the North Lake Road Bridge and a two lane collector distributor (CD) road on the south bound side of the Kwinana Freeway from Berrigan Drive to Armadale Road North facing on ramp to connect to a two lane collector distributor (CD) road (constructed as part of the Kwinana Freeway Widening project) on the north bound side of the Kwinana Freeway from Armadale Road to Berrigan Drive 1.3 Report Purpose This report documents the traffic noise impact assessment completed for the project preliminary design only. This report presents results from noise modelling and provides recommendation for required mitigation, including determining if existing noise walls along Armadale Road and the Kwinana Freeway keep traffic noise within acceptable levels to nearby receptors. An additional noise study will be required for detailed design purposes. 1.4 Scope of Work The road traffic noise assessment scope of work is as follows: Unattended noise monitoring at selected sensitive receptor sites to determine baseline noise levels. Development of a road traffic noise model based on existing and future predicted traffic flows to predict noise levels for a number of scenarios. Comparison of predicted noise levels against relevant road traffic noise criteria. Noise modelling to determine potential noise mitigation measures (if any) to be implemented as required in order to comply with relevant road traffic noise criteria. A comprehensive report on the noise model and results in accordance with SPP 5.4 Implementation Guideline. Metropolitan Road Improvement Alliance Page 5 of 41 Issue Date: 08/08/2018 Armadale Road to North Lake Road - Noise Assessment Report 1.5 Approach The road traffic noise assessment in accordance with SPP 5.4 was undertaken as follows: Identification of sensitive receptors and selection of two representative locations for unattended noise monitoring. Unattended monitoring was undertaken for one week at each site. Noise monitoring was used to provide existing noise measurements and to verify the noise model. Develop a validated road traffic noise model to assess noise impacts from the potential increase in traffic movements associated with the Armadale Road to North Lake Road project. Model implementing higher noise barrier walls to mitigate noise to sensitive receptors. The potential noise impacts associated with the traffic movements were assessed with consideration of typical SWTC requirements. The noise assessment was conducted in accordance with SPP 5.4 Implementation Guideline. 1.6 Limitations This report has been prepared by the Metropolitan Roads Improvement Alliance (MRIA) and may only be used and relied on by Main Roads WA for the purpose agreed between MRIA and the Main Roads WA as set out in Section 1.4 of this report. MRIA otherwise disclaims responsibility to any person other than Main Roads WA arising in connection with this report. MRIA also excludes implied warranties and conditions to the extent legally permissible. The services undertaken by MRIA in connection with preparing this report were limited to those specifically detailed in the report and are subject to the scope limitations set out in the report. In conducting this noise assessment and preparing the report, current guidelines for noise monitoring and assessment were referred to, including State Planning Policy 5.4: Road and Rail Transport Noise and Freight Considerations in Land Use Planning (SPP 5.4). Investigations undertaken in respect to this report are constrained by the particular site conditions. As a result, not all relevant site features and conditions may have been identified in this report. Site conditions may change after issuing of this Report. MRIA does not accept responsibility arising from, or in connection with, any change in the site conditions. MRIA is also not responsible for updating this report if the site conditions change. The opinions, conclusions and any recommendations in this report are based on conditions encountered and information reviewed at the date of preparation of the report. MRIA has no responsibility of obligation to update this report to account for events or changes occurring subsequent to the date that the report was prepared.

The project scope includes part new road construction and part road upgrade. For the upgrade works, there is no requirement to meet the targets or limits of SPP 5.4. Noise wall on the boundary of existing residences and verge of a road must not exceed 4.0 m. Noise walls on existing property boundaries more than 3.0 m high must have panels above the 3.0 m height manufactured from clear or tinted acrylic material. 2.1.2 Noise Level Objectives Noise level objectives are specified upper limits of traffic noise which apply outside residential buildings and other noise sensitive land uses (as defined in Western Australian Planning Commission State Planning Policy 5.4). They are listed in Table 2-1. The noise level objective limits in Table 2-1 must also be applied outside public buildings such as hospitals, schools, places of worship and libraries which have uses sensitive to noise.
