Residents of Glancynon Terrace in Aberaman are questioning whether Rhondda Cynon Taf Council has learned from past mistakes after a large tree growing from a retaining wall continues to threaten public safety despite repeated warnings.
The concerns echo a previous incident when a retaining wall collapsed into the Nant Gwawr watercourse after trees were allowed to grow unchecked, eventually causing the structure to fail.
Now, residents fear history is repeating itself. A large tree has been allowed to grow out of the retaining wall along Glancynon Terrace, directly above the A4095, the main highway through Cynon Valley. Despite multiple reports to the council and raising the issue at several local PACT meetings with local councillors, the tree remains in place.

The wall is showing alarming signs of failure, including significant movement, large cracks, and stones falling onto the road. One resident reported that falling rubble has already damaged her vehicle.
Frustrated residents say their efforts to get the problem addressed have been met with little urgency. “No one is interested,” one resident said.
On Friday, a contractor visited the site and informed residents that the council would need to obtain a price for the necessary work. However, locals are concerned that by allowing the tree to grow unchecked for so long, a substantial section of the wall will now need to be demolished and rebuilt, a much larger and more expensive project.
According to residents, a similar situation occurred at the same location years ago, raising questions about whether any lessons were learned from that experience.
