Renewal SA informed Adelaide city councillors last night they would remove two substantial trees from one of the city's leafiest boulevards as part of continuing landscaping developments at the North Terrace innovation precinct.
‘Adding more scalps’: Plans to fell two more trees at Lot Fourteen
Two representatives working with Renewal SA, the State Government body responsible for transforming the former Royal Adelaide Hospital site into innovation hub Lot Fourteen, notified City of Adelaide elected members of plans to axe two London plane trees on Frome Road.
Wallbridge Gilbert Aztec civil and traffic engineer, Heath Blacker, told councillors of the proposal to remove two century-old trees, located at Lot Fourteen’s gate seven and gate nine, as they posed traffic hazards.
“A critical item we look at is the pedestrian-vehicle conflict and crossing sightlines are obviously quite important,” Blacker said.
“The [gate seven] tree itself can obscure a person on that crossing for someone turning in so we raised that as a safety risk.”
Blacker said the tree at gate nine also threw up “sightline safety issues”.
“You’ve got a tree in the middle of a pedestrian crossing that can obstruct sightlines for vehicles to cars and people to cars,” he said.
London plane trees are exempt species under South Australia’s Planning Development and Infrastructure Act, meaning they are not formally considered significant.
The announcement comes two years after Adelaide city councillors voted to axe 11 century-old trees on North Terrace as part of Lot Fourteen landscaping.
Greens affiliate and area councillor Keiran Snape said the further tree removals would be “adding more scalps” to the development project.
“We can plant saplings; we can even plant semi-mature trees,” he said.
“[But] they take 50—100 years to get to the size of which we’re talking. To replace them is not an easy task.”
Snape asked whether the government had explored all other options, to which Blacker answered they had and this was the best outcome.
He said the Frome Road works were required to safely get heavy vehicles into Lot Fourteen, particularly given the constraints at the North Terrace side of the development.
“There’s a lot of pedestrians out there at the moment; there’s a tram stop,” Blacker said of North Terrace.
“We’re just trying to get, physically, these larger vehicles into the site.”
Blacker said it was “not possible” to get trucks onto the site safely on Frome Road with the trees present.
Lord Mayor Sandy Verschoor asked if the government had considered replacing the “rather substantial trees” with new ones.
Lot Fourteen senior manager of property and projects, Colleen McDonnell, said they would be “happy” to consider this option.
The City of Adelaide did not respond to questions regarding when council members were expected to provide written feedback on the proposal, and whether the council had replaced any of the previous 11 significant trees on North Terrace.
