6/2025/0551/TC Welwyn Hatfield Small Undecided Trees T1 is a tall fir tree in the rear garden. My client in the neighbouring garden Has commenced work on their extension and this tree due to its height at over 20 meters tall poses significant risk to the property if it were to fall. It is all but impossible to carry out a quality reduction of this tree to a safe height so removal is preferred. T2 is a conifer at the front of the property standing at 13 meters tall. Its right on the edge of the pavement. We wish to reduce this by 2 meters in height and shape the top so its not a flat top. This is being reduced as maintenance to minimise the risk of the tree falling over on any parked cars or across the pavement. 22 Roundwood Drive Welwyn Garden City AL8 7JZ 24/03/2025 00:00:00 /planning-applications/local-authority/WelwynHatfield/uid/362F323032352F303535312F5443 51.8064 -0.213 4190543
