1 SECTION 9 LANDSCAPE DESIGN 09 LANDSCAPE DESIGN 9.1 Design philosophy The design incorporates the fundamental objectives of landscape design in road environments including: Safe All required clear zone and safe sight distance setbacks to avoid the creation of hidden public places whilst maximising passive surveillance opportunities. Integration with local setting The design maintains and enhances existing landscape character and vegetation patterns. Ecologically sound The design uses local species from existing and adjoining plant communities and assists in protecting and recovering local biodiversity. Add character and value The design responds to and draws upon the existing landscape patterns of the area. Low maintenance and cost effective The design utilises existing site soils and local robust and durable plant species in a bold and simple way without unnecessary fussiness. Revegetation across the Project will be achieved through direct planting of containerised plant stock into prepared planting areas. This will facilitate rapid establishment of new landscape installations. 9.2 Soil preparation The following soil preparation treatments will be used throughout the project: Turf areas Eradicate weed growth Rip and cultivate subgrade profile to 200mm deep Install 150mm thick layer of weed-free topsoil Rake off to smooth even profiles Supply and install turf. Turf areas on structure Install 30mm drainage panel, overlayed with geotextile drainage fabric Install 100 thick layer coarse washed river sand Install 600mm layer 80:20 sand/soil mix Install 300mm thick layer of organic weed-free soil preblended with fertilisers and proprietary soil additive of granular water storage crystals Rake off to smooth even profiles Supply and install turf. Massed planting areas Eradicate weed growth Rip and cultivate subgrade profile to 200mm deep Install mm thick layer of organic weed-free soil pre-blended with fertilisers and proprietary soil additive of granular water storage crystals Rake off to smooth even profiles Apply 100mm layer of weed-free organic mulch Massed planting areas on structure Install 30mm drainage panel, overlayed with geotextile drainage fabric Install 100 thick layer coarse washed river sand Install 600mm layer 80:20 sand/soil mix Install 300mm thick layer of organic weed-free soil preblended with fertilisers and proprietary soil additive of granular water storage crystals Rake off to smooth even profiles Apply 100mm layer of weed free organic mulch for planting areas. Sedimentation basin planting Eradicate weed growth Install 200mm layer organic weed free soil to basin margins Rake off to smooth even profiles. Subgrades will also be tested for suitability to support plant growth and ameliorated in accordance with test results prior to installing topsoil. Organic woodchip mulch will be applied to all planting areas to a depth of 100mm. The woodchip mulch will be derived, where possible, from trees and shrubs removed through clearing works on site. Any shortfall will be made up with imported woodchip mulch. Landscape installation works will occur progressively throughout the project as projet areas and work sites become available. 9.3 Plants, planting and mulching Revegetation across the Project will be entirely though direct planting of containerised plant stock into prepared planting areas. All work will generally be undertaken in accordance with RMS standard specifications, including: D&C R178 Vegetation D&C R179 Landscape planting. The majority of planting will be: Forestry Tube containers (50mm x 50mm x 125mm deep) 150mm containers - semi advanced (150mm x 150mm x 150mm deep) 200mm containers - semi advanced (200mm x 200mm x 200mm deep 25 litre container - super advanced 75 litre container - super advanced 200 litre container - semi-mature. Install plants in accordance RMS Specifications. 211

This is further supplemented by additional tree planting of selected Eucalypts and Fig trees, beyond required clear zone safety setbacks to build green volume in this section of the Motorway. The Motorway Control Centre and Maintenance Facilities are located in this section just to the east of Homebush Bay Drive within the existing M4 road reservation and will be accessed via the Homebush Bay Drive on-ramp. SYDNEY OLYMPIC PARK N FROM PARRAMATTA The western portal precinct also accommodates the western ventilation outlet and electrical distribution facility over the western off-ramp adjacent to Underwood Road. SHEET 8 HOMEBUSH BAY DRIVE Dia Further to the east, adjacent to Ismay Avenue and north of the existing Motorway, are the fire pump storage tanks and a 33kV substation. Design details of these facilities are covered in Section 5. In terms of landscape, the buildings at Underwood Road and Ismay Avenue have a relationship to the existing local streetscape and suburban setting more so than the Motorway. The landscape design approach here is to build on the existing parkland character with new plantings of Sydney Blue Gum (Eucalyptus saligna) and Spotted Gum (Corymbia maculata) set amongst large expanses of accessible turfed parkland. Landform & Drainage New cut and fill embankments in this section will be no steeper than 1 in 3 in accordance with EIS requirements and will be trimmed and profiled to blend with the existing embankment formations in this section. There are two water quality basins HOMEBUSH BAY DRIVE TERCHANGE SALSYARD CREEK WENTWORTH ROAD SOUTH in this zone located each side of Saleyard Creek. Both basins have a spill containment functions and the western basin also has a bioretention function. The bioretention section will be planted with appropriate sedges and grasses, Landscape Works Soft landscape areas are basically a combination of turfed and massed planting areas. In this zone the intention is to maximise the available area for soft landscape works to maximise green volume to compete with the scale of infrastructure being constructed. Most landscape areas will be on natural ground however there are a number of areas where new landscape areas will be installed over cut and cover structures. Where trees are provided a minimum soil depth of1000mm will be provided. In other areas soil depths over structure will be approximately 750mm deep.

This character is drawn up into the widened verges and widened central median area of the reconstructed Wattle Street to present significant and extensive new areas of green volume created by the new turfed median and verge areas and the expansive canopies of new Spotted Gum street tree plantings that will provide much needed shade and amenity in what is currently a relatively barren street environment. The western verge of Wattle Street remains unchanged and the eastern verge is increased as part of the Wattle Street reconstruction to allow sufficient space for accommodating new street tree plantings of Spotted Gum (Corymbia maculata). Landform & Drainage A detention basin is proposed on the southern side of the Wattle Street westbound carriageway, west of Allum Street. This provides flood immunity to the road, tunnel portals and also minimises adverse flood impacts. This is a shallow basin with shallow embankment slopes and will be predominately dry other than during and directly after storm events. Elsewhere, landform profiles are consistent with existing surface profiles with only minor reprofiling to allow new works to tie-in with existing. The basic design consideration is to make the basin as shallow as possible, within the available site constraints so that it appears as part of profiled street verge rather than a basin. Most landscape areas will be on natural ground however there are a number of areas where new landscape areas will be installed over cut and cover structures. Where trees are provided a minimum soil depth of 1000mm will be provided. In other areas soil depths over structure will be approximately 750mm deep. Specifications for all soil mixes will be developed by a specialist soil scientist, for all of the various site conditions.

As with the majority of Parramatta Road this section is devoid of tree planting and presents as a barren and unfriendly environment for pedestrians and motorists alike. The only green respite along this section of Parramatta Road is offered by Ashfield Park and the grounds of Yasmar educational facility Dia 225 Dia Dia N WALKER STREET FROM PARRAMATTA To minimise the impact of the tunnel portal and to improve the amenity of the street requires extensive planting of large trees to compete with the scale of the infrastructure. The design achieves this by providing wide verge areas that provide sufficient space to accommodate new street tree plantings of Sydney Blue Gum (Eucalyptus saligna). The central median will also be planted with Hills Figs (Ficus hilli) adjacent to the ZONE 40 ZONE 50 eastbound exit to increase the green volume in this section of Parramatta Road, providing much needed shade and amenity for pedestrians and the local community. A new ventilation facility is located on Parramatta Road between Wattle Street and Walker Avenue. This facility accomodates the ventilation requirements for M4E and the future Stage 3 section. This site also accomodates the substations for M4 East and Stage 3 and fire pumps and deluge tanks. Substantial areas of new landscape are provided around the facility to allow for generous screen planting along all boundaries and extensive grove plantings of Sydney Blue Gum (Eucalyptus saligna) and Spotted Gum (Corymbia maculata) providing screening and balance to the scale of the ventilation facility.

49 APPENDIX A CONSULTATION STRATEGY 11 OPERATIONAL LIGHTG Operational lighting throughout the project generally falls across five categories: Street lighting for all surface works Cycleway and footpath lighting General external areas lighting for all service facilities Tunnel lighting Tunnel portals feature lighting. Light spill mitigation is also assessed within this section. Lighting design across the entire project is under development, further design detail will be provided in subsequent issues of this UDLP. The general design approach for each of the above general lighting categories is described below Street Lighting Street lighting across the project has been designed in accordance with AS/NZS 1158 Series - Lighting for Public Roads and Spaces which requires a Category V3 lighting system for all street lighting. Poles and luminaires are required to be in accordance with RMS standard specifications and generally consistent with existing street lighting on the area. Poles are of the galvanised steel impact absorbing type with heights and outreach arms to RMS specifications. Poles and outreach arms have been selected to achieve a typical luminaire mounting height of 10.5m. Outreach arms lengths are limited to a maximum length of 4.5m in order to maintain the required overhang for the various locations. Where possible poles will be positioned outside of the clear zone. In some circumstances poles may be mounted on or behind retaining walls and barriers. On bridges, poles will be aligned behind the bridge rail. Roadway luminaires are to RMS specifications, incorporating high pressure sodium lamps, high power factor control gear and active reactor. Street light locations are shown on the landscape design drawings in Section Cycleway and Footpath Lighting Cycleways have been provided with lighting to the performance requirements of Table 4.5 in Austroads Guide to Road Design Part 6B: Roadside Environment. This level of lighting also achieves compliance with the requirements of Category P2 lighting as defined in AS/NZS 1158 Series - Lighting for Public Roads and Spaces. Where cycleways are located directly adjacent to lit Category V roadways no separate lighting system has been provided for the cycleway. Cycleway and footpath light locations are shown on the landscape design drawings in Section General external area lighting for all service facilities General external area lighting will be provided where necessary for safety and security at the various motorway service facilities including: Motorway control centre and maintenance facility Underwood Road ventilation facility Ismay Ave 33 kv substation facility 11.4 Tunnel Lighting Tunnel lighting is a specialist activity that is required to be implemented for the safe and effective operation of the motorway in accordance with various technical standards and performance requirements including: AS/NZS :2014 Lighting for roads and public spaces - Tunnels and underpasses RMS Specification R158 Road Tunnel and Underpass Lighting. Tunnel lighting has no impact on any areas outside the tunnel environment and so there is further consideration required of potential impacts in relation to light spill Tunnel Portals Feature Lighting Each tunnel portal will also include subtle feature lighting to each entry and exit. They will provide night time interest and present a memorable experience that will brand the WestConnex motorway within the wider Sydney road network. The lighting consists of LED strip lights that are concealed in a shallow rebate within the tunnel dive approach walls. The design for the feature lighting elements is currently underway. More detail will be provided in subsequent issues of this UDLP. Concord Road substation Cintra Park Facilities Parramatta Road ventilation facility The design for these operational lighting elements is currently underway. More detail will be provided in subsequent issues of this UDLP. 259

50 SECTION 11 - LIGHTG 11.6 Light Spill Mitigation AS/NZS 1158 Series - Lighting for Public Roads and Spaces defines the general objective of a Category V lighting system as making possible the safe and comfortable movement of vehicle and pedestrian traffic and the discouragement of illegal acts. This is achieved by the lighting system revealing visual information such as the road itself, the road ahead, kerbs, footpaths, property lines, road furniture and surface imperfections, together with road users including pedestrians, cyclists, vehicles and their respective movements. The Category V lighting system will protect the integrity of the night environment through the control of upward spill light and glare. The visual requirements of motorists will predominate in a Category V lighting system. The principal design objectives of a Category V lighting system are defined in AS :2005 as follows: Luminance and luminance uniformity of carriageways to specific levels Glare control to specific levels Illuminance at intersections, verges and other locations Limitation of upward spill light from luminaires to a specific level (Upward Waste Light Ratio, UWLR) A maintenance regime whereby the lighting performance complies at all times during the maintenance cycle Minimizing energy consumption Other considerations include: Reliability and maintainability Enhancement of the visual amenity Life cycle costs Limitation of obtrusive light onto abutting properties The standard that deals with obtrusive light is AS4282 Control of the obtrusive effects of outdoor lighting. This standard sets limits on light spill at property boundaries and at the window plane of habitable rooms in residential properties for pre-curfew and post curfew hours respectively. Under section of AS4282, Public lighting is defined as follows: lighting provided for the purposes of all-night safety and security on public roads, cycle paths, footpaths and pedestrian movement areas within public parks and gardens, but not including carparks. The same section of the standard also excludes public lighting from the light spill requirements of AS4282 as follows: Public lighting has been excluded from this Standard because such lighting is provided to facilitate all-night safety and security for the public at large. Such lighting is normally supplied from the switched public lighting network. Requirements aimed at minimising the obtrusive effects of public lighting are addressed in the AS/NZS 1158 series of Standards. For traffic routes, AS/NZS has introduced the upward waste light ratio (UWLR) as a parameter to control the amount of light emitted in directions above the luminaires. Given AS4282:1997 exempts lighting for public roads from its light spill requirements, this means that any non-public roads (gated facility access roads) and carparks would comply with the light spill requirements via the selection of luminaires that offer precise light control, but public road lighting is exempt from these requirements. AS4282 has been applied to the lighting design for public roads as follows: AS4282 excludes public roads from the light spill limits within this standard on the basis of all night safety and security for the public AS4282 refers to AS for the minimisation of the obtrusive effects of public road lighting through the upward waste light ratio The public road lighting design complies with the upward waste light limits The public road lighting design is compliant with AS4282 The public road lighting design is compliant with AS Whilst luminaires incorporating a glare shield visor or a forward throw optic reduce the level of backward spill light, a trade off to this is a reduction in the overall maximum spacing between luminaires for Category V3 luminance requirements. It is also noted that whilst the glare shield and forward throw luminaire options reduce the backward light distribution, there is still a significant backward light component, as a key objective of a Category V lighting system is to also provide illumination of footpaths for safe movement of pedestrians. The Category V lighting system must also reveal necessary visual information such as kerbs and property lines. Luminaires incorporating a glare shield or consisting of a forward throw light distribution are best at minimising spill light illuminance at property boundaries and property building lines. Zone 20 does not consist of any residential properties that front onto any of the road elements. These will be utilised where required to minimise spill light illuminance. 260 WESTCONNEX M4 EAST Urban Design and Landscape Plan
