Info

Fairfield Transport Interchange Determination report be undertaken. In addition where practicable, it is recommended that 2.4m high hoardings be provided on the south and east boundaries of the Wilga Street car park worksite (i.e. the boundaries facing the Lawson Street overpass and Wilga Street) where it would be expected to provide between 5 dBA and 10 dBA additional noise attenuation. As the Laeq (15 minute) construction noise levels are predicted to exceed 75 dBA, respite periods may have to be observed by restricting the hours that very noisy activities can occur. The proposed activities in relation to the Wilga Street commuter car park are considered not significantly vibration intensive. The separation distance from the nearest receivers is sufficient to mitigate the potential impacts. All the proposed plant items are not considered to have potential to cause adverse ground-borne noise impacts. Mitigation measures to minimise potential noise impacts during construction of the extended commuter car park works in Wilga Street are outlined in Appendix 6, Condition of Approval 54 of this Determination Report.

No threatened species or ecological communities under the Threatened Species Conservation Act 1995 or the Environment Protection and Biodiversity Conservation Act 1999 have been identified on site. For further details refer to Appendix 2 of the Determination Report. The Wilga Street Commuter Car Park site is contained entirely within previously disturbed environments dominated by urban land use and predominantly exotic plants. Impacts on Ref No: 1452311 18
Fairfield Transport Interchange Determination report native flora and fauna are substantially less than would be associated with an undisturbed ‘green field’ site. The proposed works would result in some unavoidable impacts imposed upon some elements of the natural environment. These impacts will be restricted to the removal of a small area of planted native and ornamental vegetation which is not expected to impose a significant negative effect on any local populations of native biota. There are no ecological constraints at the project sites that would require modification of the proposed works or any site-specific mitigation measures required for native biota. The proposed works would proceed under a Construction Environmental Management Plan incorporating environmental management measures and vegetation offsets in accordance with the Conditions of Approval 12, 30 and 31 at Appendix 6 of this Determination Report. • Arboricultural Impacts An Arborist Report was prepared by Treescan, Urban Forest Management August 2011 to assess the impact of the Fairfield Transport Interchange Upgrade works on trees and vegetation on the northern side of the rail line and the proposed Wilga Street Commuter Car Park located on the south side of the rail line. For further details refer to Appendix 3. Trees within or along the boundary of the proposed site for the new commuter car park on the south side of the rail line would be removed. Of the trees proposed for removal only those near the railway line are considered of landscape value. These include two (2) Eucalyptus tereticornis (Forest Red Gum), one (1) Corymbia citriodora (Lemon Scented Gum) and three (3) Eucalyptus grandis (Flooded Gum). Trees to be removed to make way for the proposed commuter car park would be replaced according to Transport for NSW’s Vegetation Offset Guide 2011. Excavation for stormwater pipes may affect one (1) tree, a Washingtonia robusta (Mexican Washingtonia) and three (3) Lophostemon confertus (Brushbox). Prior root investigation and hand excavation may be required within the vicinity of these trees. Trees Platanus x hybrida (London Plane) proposed for removal in the interchange area on the north side of the rail line and along the footpath on the westbound side The Crescent are considered of minor landscape value, and would be replaced according to the landscape plan. The mature tree, Lophostemon confertus (Brushbox) located adjacent to Platform 1 would be retained and the proposed new garden bed within the vicinity of the tree should improve on the currently poor soil conditions, as long as care is taken to retain existing levels and to avoid root injury when designing and constructing the retaining wall. Mitigation measures for the protection of the trees to be retained and vegetation offsets for the trees to be removed are outlined in Appendix 6, Conditions of Approval 30, 31, 42, 43, 44, 45 and 52 of this Determination Report. 5 Conditions of Approval for Fairfield Transport Interchange Upgrade If approved, the Proposed Activity will be allowed to proceed subject to compliance with the Conditions of Approval included in Appendix 6 of the Determination Report.
