Electricity cables ‘re-rooted’ to protect ancient tree
UK Power Networks has adapted a central London cable route to protect the roots of what is said to be the capital’s “oldest tree.”
The famous London plane tree on Cheapside near St. Paul’s Cathedral is said to have been in that very spot since 1855, with some speculating even earlier, in the 18th Century.
The tree’s protected status ensures that it will carry on standing tall for years to come and with this in mind, UK Power Networks adapted a cable ‘root’ on Wood Street to make sure it does.
The electricity firm’s designers and engineers identified that a cable route close to the tree’s deep and widespread root system could cause harm.
To prevent this, trial holes were dug to make sure the roots were not crossing paths with potential works.
The route also made sure to avoid the Grade I listed building Guildhall and its surrounding conservation area, with the help of specialist environmental contractors.
When the excavation work approached the canopy of the tree, only hand-digging methods were permitted.
This project shows how vital upgrades to the electricity network in the capital can be delivered while safeguarding the natural and historical landmarks in the city.
James St John Davis, Chair of the City of London Corporation’s Natural Environment Board, said: “When infrastructure projects stop and change course for a single tree, it speaks volumes.
“UK Power Networks have gone to impressive lengths to protect what is believed to be one of the oldest and most historically important trees in the Square Mile – a truly living piece of the City’s history.
“As custodians of more than 11,000 acres of green and open spaces across London and the southeast, we know how rare and irreplaceable these landmarks are. This is a powerful example of how modern infrastructure and heritage can coexist, delivered with real sensitivity to our natural and historic environment.”
Assistant project manager, Chanelle Mistry, said: "London’s heritage is irreplaceable, and at UK Power Networks we’re determined to protect it while keeping the capital powered.
"When our teams realised this historic plane tree could be at risk, we acted quickly to adapt our plans to safeguard it. Projects like this show how we can modernise the electricity network responsibly, without compromising the landmarks that make London special."
In addition to protecting the tree, the project picked up the ‘Streetworks Communication’ award at the The City Corporation's Considerate Contractor Streetworks Scheme.
