Reason for works

As part of the NSW Government initiative to plant five million trees for Greater Sydney by 2030, Council will be working alongside the NSW Government to create a greener NSW to improve our health, climate, economy and environment.

We have received grant funding from the NSW Government to plant 3,000 new trees across Sutherland Shire in 2020.

Our aim is to ensure the ongoing health and well-being of our people and environment. More tree canopy means healthy people, more shade, cooler suburbs (by reducing the heat island effect), more homes for our wildlife and even an increase in property values.

Scope of works

We will be building on our existing Green Streets program by planting 3,000 new trees in various streets and reserves, schools and community spaces across Sutherland Shire in the suburbs of:

  • Taren Point
  • Jannali
  • Engadine
  • Cronulla

The four precinct locations were selected following mapping and analysis which showed that canopy cover was low, and there is opportunity for street tree planting in these areas.

The project will use suitably sized, local Indigenous species that reflect the plant communities that would have existed prior to urbanisation. The stock will be grown primarily by Council’s nursery from seed and cuttings collected by experienced Bushcare staff and volunteers, preserving local provenance. 

The trees will be planted at 200mm pot size, have a 2 year establishment period to water, maintain and formatively prune the new trees.

Project schedule

The delivery milestones for this project are: 

  • November 2018 - Grant Application Submitted
  • February 2019 - Grant Funding Awarded
  • February 2019 to Jan 2020 – Trees grown at the Native Plants Nursery in Gymea
  • End August 2019 - 3K Trees 2020 project launch
  • September to November 2019 – Information sessions and tendering
  • April 2020 – Tree planting commences
  • August 2020 to 2022 - Ongoing tree maintenance & establishment activities.

Public impacts during construction

There will be no need to close local parks/reserves or interrupt the normal operation within a road reserve to undertake this work.  No other impacts to the public or normal park operations are anticipated, at this time.

Funding

This project is jointly funded by the NSW Department of Planning and Environment and Sutherland Shire Council.

Council was successful in securing four (4) Grant funding applications (one for each suburb listed above) under the State Government's "5 Million Trees for Greater Sydney" Program.

 

FAQ’s

A key direction of the Greater Sydney Commission South District Plan is to increase urban tree canopy and deliver ‘Green Grid’ connections. Council’s Community Strategic Plan also sets a target of no net canopy loss. Council currently has a number of strategies that facilitate ‘green’ connections. The Greenweb strategy protects and enhances biodiversity corridors. The Green Streets program facilitates increased street tree planting and urban tree canopy. By planting more trees, council can meet these initiatives to create a Green Grid throughout the Sutherland Shire of high quality green spaces and tree lined streets that support walking, cycling, and community access to open spaces. Planting trees will improve the liveability of the Sutherland Shire, create healthy places, and mitigate the effects of climate change.  

The NSW Government - Greater Sydney Grant Program is focused on working with everyone in Sydney to plant Five Million Trees (5MT) by 2030.

That’s more trees in our streets, parks, backyards, neighbourhoods and schools, so we can grow our tree canopy from 16.8%* to 40% (*source Office of Environment and Heritage, 2011).

More tree canopy means more shade, cooler suburbs (by reducing the heat island effect), more habitats for our wildlife and even an increase in property values.

To minimise confusion to the community as well as Council staff participating involved in tree planting, Sutherland Shire Council is referring to this project as “3KT” meaning the 3,000 trees we aim to plant in the Sutherland Shire.

The Five Million Trees for Greater Sydney (5MT) Grant supports local councils in Greater Sydney to enhance urban tree canopy by co-funding tree planting projects dollar for dollar in public spaces such as streets, parks and plazas.

A total of $6 million of funding was available in 2018-19 to assist councils to plant thousands of more trees across Greater Sydney to increase tree canopy cover.

Thirty-two projects have been awarded funding totalling $5,378,407 across 20 councils in Greater Sydney.

As part of the 3KT project, the existing canopy cover of the Sutherland Shire was mapped and broken down into canopy cover percentage categories. Council officers reviewed this mapping and looked to find projects throughout the Sutherland Shire where the canopy had either been largely removed due to ageing street trees, historical development decisions, or where evident gaps exist between large tracts of bushland where infill planting would prove beneficial. Council officers also looked at other strategies Council currently has in place (e.g. Green Grid, Greenweb, Green Streets) to determine appropriate locations for planting to achieve the outcomes of these strategies and align with the overarching aim of no net canopy loss as set by Council’s Community Strategic Plan. The selected suburbs satisfied the criteria we were after and presented great opportunities to replant.

Council has currently carried out over 120 Green Streets projects across the Sutherland Shire since its inception in 2014. In September 2019 we will planting our 10,000th tree.

Council’s aim is to ensure we are creating beautiful streetscape spaces that provide shade and support the wildlife that live in these locations. All trees planted are selected from Council’s Native Plant Selector. This tool specifies species that would have existed in the local ecosystem prior to urbanisation. These species will have greater resilience in local conditions. Sutherland Shire Council is also a participant of the ‘Which Plant Where’ program at Western Sydney University, which aims to road-test tree species for resilience in our changing Sydney climate. Species that fail to prove hardy have been eliminated from the street tree species pallet for this project. Council will also work with infrastructure providers and asset owners to ensure we are selecting the right species in the right spots for the long term. Site constraints and the trees size at maturity are all considered as part of the design process.

This program relates to tree planting in streetscapes. While there is no proactive tree assessment process included in the scope of this project, any tree identified for high priority maintenance will be referred to Parks Operations for further determination. If you have a street tree that you would like Council to inspect please refer to the http://www.sutherlandshire.nsw.gov.au/Home/Report-It

Please see the Maps included at the top of the page of the four precinct areas included under the 3KT project.

As part of the 3KT project, trees will be planted by Council on the nature strip in suitable locations. Planting on private property is also encouraged, and Council can provide plants for you to plant in your own yard. This will support the planting on public land undertaken by Council as part of this project.

Council welcomes suggestions for streets to be planted, and many of the historical green streets projects have been nominations from the community. The 3KT program is limited to the streets outlined in the four suburbs (Cronulla, Jannali, Taren Point and Engadine), however Council is always open to suggestions for future street tree planting areas under its Green Streets Program. For more information and how to suggest a street for future planting, please see the attached link: http://www.sutherlandshire.nsw.gov.au/Residents/Trees/Trees-on-Council-or-Public-Land/Street-Tree-Planting.

Yes. Ongoing maintenance is critical to the success of this project and the tree’s long term health and form. Each tree planted as part of this project will be on a two year maintenance program. All trees planted will be provided with watering, follow up maintenance and formative pruning until establishment.  

The urban tree canopy is the term used for trees and bushland within the urban area. Within the Sutherland Shire the urban tree canopy is made up of trees along streets, in parks and other public spaces, and on privately owned land including front and backyards. The urban tree canopy has a range of benefits including, but not limited to:

  • Increasing your properties value
  • Thermal insulation for your home (winter and summer)
  • Reducing stormwater runoff
  • Improving air quality
  • Reducing the Urban Heat Island effect
  • Being nature’s sunscreen proving UV protection
  • Increasing places and spaces for our birds and wildlife to go
  • Making an area beautiful, private and liveable
  • Reducing traffic noise

Canopy loss is the ongoing net loss of trees in an area. The loss of canopy has a number of negative impacts on the environment as a whole. Clearing of trees and vegetation increases erosion and sedimentation of waterways and reduces water and air quality. Clearing also removes habitats leading to the fragmentation of biodiversity and the direct loss of native plants and animals. Canopy loss also has significant impacts on the amenity of a neighbourhood by increasing the ambient temperature of the area, reducing shade on footpaths and cycleways as well as reducing property values in areas where canopy cover is low. There is a direct correlation between affluent suburbs and higher canopy cover. 

The Urban Heat Island effect is localised warming due to the increase in the large amounts of paved and dark coloured surfaces like roads, roofs, and car parks as a result of urban development. The sun’s heat is absorbed not reflected, and causes the surface and ambient temperatures to rise. Canopy trees provide shade and play a significant role in reducing the effects of urban heat on an area because unlike hard surfaces, trees and vegetation reflect heat and actively cool and clean the air. Every 10% increase in tree canopy cover can reduce land surface temperatures by 1.13 degrees Celsius.

Trees certainly make neighbourhoods a more pleasant place to live. There is now evidence that tree lined streets increase property values. There are a number of studies from various universities including University of Queensland, Macquarie University, University of Tasmania and Griffith University that support the correlation of affluent suburbs with an increase in the number of street trees in the street.
 
 
Increased canopy cover is linked to an increase in property values according to Aecom’s Green Infrastructure: A Vital Step to Brilliant Australian Cities. This report compiled urban data analytics across different Sydney suburbs and found that for every 10% increase in canopy coverage within the street corridor, the value of the properties increased by an average of $50,000.

Council supports resident’s participation in its Green Streets program. Please contact Council’s Green Streets team for further information on 9710 0333.

The aim is to minimise future conflict between street tree planting and infrastructure in the public space.  Council has a implemented processes to identify to the best of its ability the most appropriate locations using suitable sized species to reduce conflict with services and infrastructure. During the design process, one of the key stakeholders to review the position of trees in the public domain is the footpath asset management team. Their role is to ensure there is no conflict with known proposed footpaths. Trees are considered during the process of road crossing applications.

The four precinct locations have been analysed and highlighted as areas with low canopy cover. Council is happy to engage with the community and address their concerns relating to tree size or location. Council will consult with residents during the design stage. Where individual residents have concerns, we encourage them to contact council to discuss an outcome that best satisfies the residents as well as Council’s canopy cover targets.

Ausgrid and Sutherland Shire Council are working together to improve community safety, power supply reliability and to maintain the area’s leafy character by continuing projects that will replace damaged trees underneath power lines. This will take some time due to our LGA size and the number of street trees.

Ausgrid and Sutherland Shire Council have agreed on a suitable list of smaller growing species that we can plant under wires that won’t grow to compromise power lines and public safety. In addition to this, formative pruning at an early age will maximise good branch architecture for the tree’s long term form.

Pruning of trees under power lines is carried out by Ausgrid contractors. Ausgrid has a new approach to trimming trees under power lines. Ausgrid and the contractors each employ a horticulturalist and arborist to make sure the trimming is done to standard and the trees remain healthy.
