2.1 Description of the Proposal

Main Roads Western Australia (MRWA) proposes to construct a new 38 km long section of the Perth–Darwin National Highway (PDNH) between Malaga and Muchea, in Western Australia (the proposal) (Figure 1). The proposal is a highway and will connect the intersection of and in the south with and in the north.

There will be no clearing of native vegetation specifically for laydown areas. All laydown areas will be established in areas that are already cleared, or within the permanent footprint of the proposal. No laydown areas will be constructed within the wellhead protection zones in the Gnangara Underground Water Pollution Control Area (GUWPCA).

3.3 Fauna Underpasses, Bridges and Fencing

By providing connectivity between severed habitats, fauna underpasses and bridges installed along the alignment will minimise direct and indirect impacts from the proposal to conservation significant terrestrial fauna, such as those that arise from the fragmentation of habitat and fauna populations. The underpass and bridge designs and locations are described in Table 4 and depicted in Figure 3. The designs and locations are consistent with the Fauna – Construction – Condition Environmental Management Plan as required by condition 12 of the Ministerial Statement. Most underpasses will be of a box culvert design (Appendix A) and some will provide for dual use; i.e., cross-highway drainage as well as the movement of fauna under the highway. Appendix B shows the concept design for the fauna bridge. Dimensions given in Table 4 refer to the internal space available to fauna within the fauna underpass or bridge structure. The fauna fence locations are depicted in Figure 3. All fauna fencing will be 1,800 mm high and will be returned from the boundary over the fauna underpasses to ensure continuous fence line. The fauna fence will be constructed to guide fauna to the underpasses. All fauna fencing will be supplied and installed in accordance with Australian Standard AS1725. Dimensions for the fauna fences are provided in Appendix C.

Drainage design aims to maintain the existing hydrological regime throughout the proposal development envelope. Culverts and bridges installed along the alignment will minimise impacts to hydrological regimes of surface water from the proposal. The culvert design and locations are summarised in Table 5 and depicted in Figure 4. Most culverts will be of a box culvert design (Appendix A) and some will provide for dual use; i.e., cross-highway drainage as well as the movement of fauna under the highway. The dimensions for the culverts will be confirmed during detailed design.

Bio-retention swales and infiltration basins installed along the alignment will minimise impacts from the proposal to the quality of groundwater and surface water within the vicinity of Ellen Brook and within the GUWPCA. Table 7 and Figure 5 show the location of the bio-retention swales and infiltration basins in the vicinity of Ellen Brook and within the GUWPCA. The design of the bio-retention and infiltration systems are consistent with the approved Inland Waters Environmental Quality – Hydrological Processes – Condition Environmental Management Plan as required by condition 13 of the Ministerial Statement and will consist of an excavated basin or trench that is filled with porous media and planted with vegetation (BG&E, 2015). Figure 6 shows the design of a typical bio-retention swale and infiltration basin.

Noise walls, installed to mitigate existing noise sensitive receptors south of Maralla Road, will minimise impacts to amenity as low as reasonable practicable. The locations, lengths and heights of the noise walls are shown in Figure 7. Noise walls will have a maximum height of 5 m and will be constructed using materials with a surface density exceeding 15 kg/m2.
