  20 Albany Close Esher Surrey KT10 9JR

  Tree Preservation Order EL:89/15 - T1 - Oak - reduce overall by 3m and raise canopy up to 5m by removing secondary branches to leave a finished height of 15m and a finished spread of 9m. The Oak has developed into a large tree for its present location within a relatively confined rear residential garden, with the crown extending in close proximity to the boundary with the neighbouring property. The proposed works are intended to manage the tree's overall size and crown dimensions in relation to its setting, while retaining its contribution to the local amenity. The proposed work will maintain the tree at a more appropriate scale for its location and will provide greater clearance from the neighbouring property and improve the relationship between the tree and the surrounding residential garden environment. The works are intended as a proportionate management measure rather than removal of the tree, allowing the oak to be retained while reducing its current size and encroachment within a confined residential setting.
