4 1. Introduction The WestConnex scheme is a NSW Government initiative connect Sydney s west and south-west with the Sydney Airport and Port Botany precinct. It is being delivered by the Sydney Morway Corporation (SMC), formerly the WestConnex Delivery Authority (WDA). Part of that project is the WestConnex Stage 2, referred as the New M5. The project will run from the existing M5 East corridor at Beverly Hills via a tunnel St Peters, providing improved access the airport, South Sydney and Port Botany precincts. The Project will substantially improve the east - west corridor access between the Sydney CBD, Port Botany and Sydney Airport precincts and the South West growth areas. The project will deliver approximately nine (9) kilometres of two-lane twin tunnels with capacity operate three lanes in the future, morway morway connections the King Georges Road Interchange Upgrade at Beverly Hills, and a new interchange at St Peters. Infrastructure Approval was granted for the project on 20 April Major works are expected commence in mid-2016 and the New M5 tunnel is scheduled open traffic in late The CPB Contracrs Dragados Samsung Joint Venture (CDS-JV) has been awarded the design and construction of the New M5. CPB Dragados Samsung Joint Venture (CDS-JV) has commissioned prepare an Arboricultural Impact Assessment Report for the proposed road construction along Gardeners Road, Bourke Road and the bridges (Bridges 8&9) connecting Gardeners Road and St Peters Interchange, along with ancillary infrastructure (footpaths and services). The proposed works are part of the WestConnex New M5 Development Project. The purpose of this report is : Identify trees that are likely be affected by the scope of works. Assess the current overall health and condition of the subject trees. Evaluate the significance of the subject trees and assess their suitability for retention. The Report has been developed mirror the same requirements of the reports previously approved Department of Planning and Environment (DPE) and addresses the requirements of Condition B63 in accordance with Table 1. 4

5 Table 1: Condition of Approval B63 Compliance Table Condition Requirement Addressed in: B63 The SSI must be designed retain as many trees as possible and provide a net increase in the number of replacement trees. The Proponent must commission an independent experienced and suitably qualified arborist, prepare a comprehensive Report(s) prior removing any trees on the periphery and/or outside the construction as identified in the figures in Section 6 of the document referred in condition A2(b), including any tree(s) removed along Eusn Road. The Report may be prepared for the entire SSI or separate reports may be prepared for individual areas where trees are required be removed. The report(s) must identify the impacts of the SSI on trees and vegetation within and adjacent the construction. The report(s) must include: This Report B63(a) B63(b) B63(c) A visual tree assessment with inputs from the design, landscape architect, construction team; Consideration of all options amend the SSI where a tree has been identified for removal, including realignment, re of services, redesign of or re of ancillary components (such as substations, fencing etc.) and reduction of standard offsets underground services. Measures avoid the removal of trees or minimise damage existing trees and is ensure the health and stability of those trees be protected. This includes details of any proposed canopy or root pruning, excavation works, site controls on waste disposal, vehicular access, and srage of materials and protection of public utilities. Section 4a: Site Observation Section 4c: Documents Inputs, Meetings and Plans Referenced Section 4c: Documents Inputs, Meetings and Plans Referenced Section 7: Recommendations In the event that trees are be removed, then replacement trees are be planted within, or in close proximity, the SSI boundary, including along Eusn Road where feasible and reasonable. The of the trees must be determined in consultation with the relevant council(s). The replacement trees are have a minimum pot size of 75 litres. A copy of the report(s) must be submitted the Secretary for approval prior the removal, damage and/or pruning of any trees, including those affected by site establishment works. All recommendations of the report must be implemented by the Proponent, unless otherwise agreed by the Secretary. Consistent with earlier approved Reports replanting will be detailed in the Urban Design and Landscape Plan in consultation with relevant councils. 5

6 2. Study Area The study area comprises of the following areas: Approximately 65ha of land situated along and surrounding Gardeners Road. The northern and southern extents of the study area are bound by industrial buildings and offices. The western end of the foot print extends from Gardeners Road through private land, over Alexandra Burrows Road. The eastern extent is the tie in of the upgraded Gardeners Road the existing road corridor. This is presented in Map 1. Any future works that may affect trees beyond the study area will be addressed in a tree report prepared and approved before any such works. 6

8 3. Scope of Works Gardeners Road will be upgraded permanently a five (5) six (6) lane carriageway with access and egress the surrounding road networks. Works include: Demolition and clearing. Earthworks. Drainage and utility works. Provision of local parking. Shared cycle and pedestrian paths. Signal upgrades. Road construction. Ancillary works. The width of the upgrade cannot be lessened without compromising safety design considerations and for this reason the design width cannot be decreased. The of the road widening is provided in Chapter 5 and is represented by the full width of the Project Deed boundary. An overview of the Project Deed Boundary, relevant this report is presented in Map 2. 8

10 4. Methodology a. Site observations The subject trees were inspected between 1 st December 2016 and 20 th February 2017 by. All the trees, taling 383 trees (grouped as 364 trees), within and adjacent the boundary of the project have been surveyed by a surveyor from CDS-JV. These trees have been identified in Chapter 5. Details on species; measurements of height, canopy spread, diameter at breast height (DBH), Protection Zones (TPZ) and Structural Root Zones (SRZ); and an assessment of the health and structure of the subject trees is contained in Appendix A. s located outside of the specified study area have not been included in this report. If trees located outside of the study area are likely be impacted, additional arboricultural assessment will be required. b. Visual Inspection (VTA) The subject trees were assessed in accordance with a stage one Visual Assessment (VTA) as formulated by Mattheck & Breloer (1994), and practices consistent with modern arboriculture. The following limitations apply this methodology: s were inspected from ground level, without the use of any invasive or diagnostic ols and testing. s within adjacent properties or restricted areas were not subject a complete visual inspection (i.e. defects and abnormalities may be present but not recorded). No aerial inspections or root mapping was undertaken. heights, canopy spread and diameter at breast height (DBH) was estimated, unless otherwise stated. identification was based on broad taxonomical features present and visible from ground level at the time of inspection. 10

11 c. Documents, meetings and plans referenced Inputs from the design, landscape architect and construction teams were incorporated between December 2016 and March Representatives include: CDS-JV Construction Project Manager, Local Road Works CDS-JV Senior Environment Advisor, Local Road Works CDS-JV Design Coordinar, Local Road Works Hassell Studio Landscape Architect. The CDS-JV GIS was used review tree assessment in the study area and the road design. Options amend the State Significant Infrastructure (SSI) for this area were considered. The road corridor has been designed be as narrow as possible while conforming relevant design standards. The road corridor and supporting pedestrian and cycling networks are built the boundary. Altering pathways in order retain any trees in addition that already specified in this Report would require re of the pathway in the road corridor, in third party property, or complete removal. As a result, there are no further opportunities reduce the road corridor without compromising road safety, access and design standard compliance. Utilities and services (water, sewer, communications, power) are required be installed in the al set by the public utility provider (as owners of these assets). These als are typically located in the pathway construction allow future maintenance works be carried out without working in the road corridor. The construction methodology has also been considered in preparation for this report. Pruning, non-destructive digging techniques and changes design have been considered and will be implemented so as maximize opportunities retain as many trees as possible. The final urban design and landscape plan will address the planting of trees, where feasible and reasonable, within the SSI boundary in accordance with the Conditions of Approval. The conclusions and recommendations of this report incorporates the input from the design, urban landscape and construction, identifies both trees be retained and those needed be removed in order deliver the pieces of infrastructure required by the project and are based on Australian Standard AS : Protection of s on Development Sites. 11

23 6. Impact Assessment & Results This impact assessment has been undertaken in accordance with the Australian Standard, AS , Protection of s on Development Sites. It includes an assessment of retention, tree, in TPZ, cause of, proposed and reasons for proposed. Results are contained in Table 2. a. Value takes in account the significance of each of the subject trees and an assessment of their health and suitability for retention within the development site (refer Appendix B). b. The of a tree is one of the primary contributing facrs the level of impact likely be sustained by the proposed construction activities. s inside the - s located within the construction cannot be retained without design modification. In order retain significant trees, design modification or the use of tree sensitive (alternative) construction methods may be recommended. s outside the - s located outside of the construction, which are not likely be significantly impacted by the proposed works can be successfully retained. These trees will require tree protection and ongoing moniring throughout the entirety of the project. s adjacent - s located adjacent the construction or proposed construction activities may be impacted. These impacts will be determined by the level of that is likely occur within the TPZ. s located within areas not yet finalised/approved for construction will require further assessment. If the final level of cannot be determined based on information provided the arborist at the time of inspection, further assessment will be required. c. Encroachment in TPZ Encroachment includes, but is not limited : excavation, compacted fill, machine trenching, ground penetration, soil disturbance. None - The tree is located outside of the proposed and is unlikely be affected by construction activities. Minor Encroachment - If the proposed is less than 10 (tal area) of the TPZ, and outside of the SRZ, detailed root investigations should not be required. The area lost this should be compensated for elsewhere, and be contiguous with the TPZ. 23

24 Major Encroachment - If the proposed is greater than 10 of the TPZ or within the SRZ, the project arborist must demonstrate that the tree(s) remain viable. This may require root investigation by nondestructive methods. The area lost this should be compensated for elsewhere, and be contiguous with the TPZ. When determining the potential impacts of in the TPZ consideration will need be made the and distribution of the roots, including above or below ground restrictions affecting root growth. Location and distribution of roots may be determined through Non-Destructive Excavation (NDE) methods such as; hydro-vacuum excavation (sucker truck), air spade and manual excavation (hand ols). Root investigation is used determine the extent and of roots within the zone of conflict. Root investigation does not guarantee the retention of the tree. d. This determines which particular part of the proposed construction activities will cause the impact the tree. e. The proposed is the recommended solution for conflicts between trees and the proposed works. Remove - is recommended for complete removal. s may be recommended for removal regardless of their. Removal may be recommended based on the species, health, structure, or risk associated with the tree. Retain - can be successfully retained. s suitable for retention will require tree protection and / or minor pruning and cutting, and ongoing moniring in order ensure their ongoing health. f. Provides a brief explanation for why the proposed was recommended. 24

86 7. Recommendations A tal of 383 trees (grouped as 364 trees) were inspected and assessed within the study area. 285 trees (grouped as 266 trees) are marked for removal. 98 trees are marked for retention. 219 trees (grouped as 200 trees) are located wholly within the development and cannot be retained due the need conduct significant excavation and / or filling in order deliver the required infrastructure. These trees are recommended for removal. 154 trees are adjacent the development. 66 have been recommended for removal as they will be significantly impacted by fill required build the road corridor, pedestrian and shared pathways, install utilities and deliver the new bridge connecting Gardeners Road the St Peters Interchange. Permission from the landholder must be obtained prior removal of trees on third party land. 88 trees have been recommended for retention. These trees are located adjacent the proposed works and will require tree sensitive construction techniques and/or further arboricultural input in order reduce impacts these trees. 10 trees are outside the and are not anticipated be impacted by the works. a. protection The following tree protection measures will be required for the 88 trees adjacent the works that are suitable for retention (see Table 2). protection fencing must be established around the perimeter of the TPZ of potentially affected trees. If the protective fencing requires temporary removal, trunk, branch and ground protection must be installed and must comply with AS Protection of trees on development sites. Any additional construction activities within the TPZ of the subject trees must be assessed and approved by the project arborist, and must comply with AS Protection of trees on development sites. If any changes are made Protection Fencing it must be authorised by the site arborist prior the fencing being removed. Further information and guidelines on tree protection if required can be provided by. b. Inspections The site arborist or equivalent will supervise excavations within the TPZ of trees being retained. Scheduled inspections should be undertaken for all subject trees assessed for retention during the course of construction. Normally this is every two (2) weeks. Site diary for Arboricultural works must be kept at the onsite 86

87 office for the duration of the project. All matters pertaining tree management must be documented in this diary and signed of as each issue is resolved. s outside of the study area that may be impacted during the works will require additional Arboricultural Assessment. 87

88 c. work All pruning and/or tree removal work is be carried out by, or under supervision of, an arborist with a minimum AQF Level 3 qualification in Arboriculture or equivalent. All pruning must be in accordance with Australian Standard AS , Pruning of Amenity s. All pruning and/or tree removal work is be carried out in accordance with the NSW WorkCover Code of Practice for the Amenity Industry (1998). Reference should also be undertaken for any tree works the SafeWork Australia Guide Managing Risks of Trimming and Removal Work Permission must be granted from the relevant consent authority, prior removing or pruning of any of the subject trees. material be used for landscaping where practical or disposed of offsite. 88
