  8. Decided - Granted6/2025/0810/TPO

    TPO 819 - T1: Pine tree. There has recently been some heavy winds to which multiple branches have snapped out on the tree leaving damaged branches and some hanging branches still in the tree. We are unsure if there is potential for further damage that can't be seen from the ground. The tree is overhanging the immediate roadway which is also used as a walk through. There is a high risk hazard in its current state and we would require the tree to have the damaged branches removed and reduce the remaining canopy by approx. 30% to suitable growth points to relieve some weight and to try and blend the gap in the canopy from the fallen branches. Due to the location and health and safety aspect we would like to carry out these works as soon as possible please.
