    2025/3314/TPO Submitted 13 Aug 2025 50 yards away

    T1 is a mature ash tree located to the front garden of no.2 chapel close. The tree is within striking distance of multiple properties and has recently lost significant dead branches within the upper crown. The tree is suffering from ash dieback and is producing large amounts of deadwood. I would recommend a fairly heavy crown reduction of the upper crown. Reducing the height by 6-7m and the lateral crown spread by around 3m to blend into the upper crown. This will help retain the tree and hopefully promote new growth.
