Western Harbour Tunnel Upgrade: Tree replacement strategy for North Sydney revealed

Transport authorities have released a long-awaited tree replacement strategy for the Western Harbour Tunnel and Warringah Freeway upgrade. See the plans here.

Transport for NSW has released its long-awaited tree replacement strategy for North Sydney in relation to the multi-billion Western Harbour Tunnel and Warringah Freeway upgrade.

Under planning approval conditions, trees will be progressively replaced at a ratio of 2:1 along the project area with a net increase in overall tree canopy coverage.

Replacement tree planting at Cammeray Golf Course is also set to commence in late 2022 for its 2023 reopening.

Sydney blue gum, smooth-barked apple and broad-leaved paperbark are among the tree species that will be planted to ensure ideal canopy coverage.

A spokesperson from Transport for NSW said the principles of the tree replacement program was to deliver benefits to the impacted community, reinstate quality open and green space and meet approval requirements.

“Transport will work with North Sydney Council to refine and adapt these principles … to provide a framework for the selection of specific tree locations and species,” the spokesperson said.

“The project teams will prioritise tree replacements … where these three principles most overlap – providing benefits to people and communities, the environment and places and with efficient and viable delivery in mind.”

The announcement comes after more than 800 residents signed a petition and placed paper trees at Cammeray Park to protest against the project over concerns over loss of canopy and the removal of over 500 established trees.

Willoughby State MP Tim James said the major condition of the projects was the replacement of any lost trees two for one with the enhancement of the local tree canopy.

“I have firmly and consistently expressed the desire that we not only restore our precious green, open spaces but ensure our tree canopy and natural environment is expanded, thriving and even better than it was before,” Mr James said.

“For every tree removed, two trees will be replanted, and in finalising the strategy the project is asking the local Willoughby community to help determine the best replacement tree species, sizes and locations.

“I encourage our community to have a read of the proposals outlined in the draft strategy and submit your feedback so that we ensure that our local voices are heard.”

Community members and residents raised concerns in November 2022 about the Western Harbour Tunnel Upgrade when dead ducks were found near construction sites after a duck dam was removed at Cammeray Park.

Mr James highlighted that community input was integral for this major infrastructure project in a press release after the NSW Government announced the Sydney Harbour would not be dredged for the Western Harbour Tunnel harbour crossing.

“As I have long said, meaningful community input is central to these major projects.” Mr James said.

“While there is much to be pleased with in this announcement, I know there is more to do … I will continue to advocate refinements and enhancements to further improve this project for the Willoughby community.”

Once feedback from the community has been received and considered, the State Government will work in partnership with North Sydney Council to finalise the strategy and implement a replacement tree program.

The draft tree replacement strategy is on public exhibition from December 7 until February 5 2023.
