Pavement tree is damaging my wall.

A maple tree planted in the pavement is too close to my wall and is causing damage. A leading Cardiff arborist advises the wall is likely to collapse into the pavement. In an almost identical case across Valarian Close but on land owned by 11 Water Avens Close, the owner had a similar tree removed by the Parks Department and was told that his piece of land was being adopted by the council who still appear from time to time to manage vegetation. I’d like the Parks Department to investigate and take appropriate action to prevent a H&S issue whereby a passing member of the public could be injured if the wall collapses. Previously reported to the Parks Department with my last email remaining unanswered. Also reported to our MP and local councillor.
