The open spaces across the project area will incorporate a range of active and passive recreational activities for the community. Some open spaces will include facilities such as a playground, barbeque facilities, seating and shelter structures, making the open spaces more desirable locations for the community.
Trees removed as part of the project are being replaced with mature native evergreen trees along the road verges and medians, where room is available, and pockets of deciduous trees in community parks / open space areas where appropriate. Native shrubs, grasses and ground covers form the understorey planting and feature in various locations across the project footprint.
An objective of the T2T project is to achieve a net gain of greater than 20% in biodiversity value across the project area, compared with the pre-construction value, meaning we are planting more vegetation in the area than ever before. This gain applies to the area of planted sites and the number of trees that existed prior to construction, and to the habitat that was originally available in the vegetated areas.
The landscaping plans have been finalised in consultation with local Councils and the Department of Planning Transport and Infrastructure (DPTI) to ensure they are sustainable.
road corridor is being landscaped with the key features being:
William Street Park, Croydon, this park was designed by members of the Croydon community who participated in a working group last year, along with T2T Alliance, DPTI and City of Charles Sturt Council representatives. The park features native play space areas, a BBQ area, seating and shelter, along with a community chalk board and an etched urban design feature panel on the back of the noise wall. A memorial and small reflection space to honour the former Church of Christ, also features in this park.
Jervois Avenue Park, West Hindmarsh, following feedback from the local community and our consultation process, this park now includes gym equipment and a fenced area for dogs.
The stormwater detention basins located at Harriet Street, Flanders Street, Lamont Street, Princes Street and Forster Street, each including key landscaping elements.
The Outer Harbor shared use path ramp at McInnes Street.
The Port Road grassed median with a formalised row of trees near Queen Street where there is no conflict with extensive utility services
Parcels of land adjacent South Road between the footpath and the noise wall will contain a combination of trees, ground cover and grass depending on the size of the area.
Verges, the area between the kerb and the footpath, will be compacted rubble and planted with mature trees and mulch where space is available and future viability is unquestioned (i.e. where there is no conflict with utility services).
Mature trees were purchased in 2017 from local nurseries who are currently maintaining the trees and growing some smaller plants to be established across the project. While landscaping works are continuing across the project area, the placement of top soil and plantings will not be completed until the second quarter to avoid planting in the heat of summer. The planting species can be viewed below.
Minimisation of project related construction and operational noise and vibration is a major consideration for the project.
A range of treatment measures to reduce noise have been incorporated into the design including:
Selection of asphalt types
Lowering the road
Installation of acoustic barriers on the side of the rail overpass
Noise barriers have been installed along the road corridor to offset short-term and long-term noise impacts for the local community.
Construction activities will comply with requirements of the Department of Planning, Transport and Infrastructure Road Traffic Noise Guidelines and the Environmental Protection Authority Guidelines for the assessment of noise from rail infrastructure.
