Tree Preservation Order
30 Jul 20262026/1858
2 Fisher Close Hersham Walton-On-Thames Surrey KT12 5PNElmbridge

Tree Preservation Order EL:183 - T1 Chestnut approximately 16m in height with a crown spread of 9m. Fell to ground level due to the tree being dead. Reason for the proposed works: The tree is dead and should be removed in the interests of safety. The client is willing to undertake replacement planting; however, a suitable location within the garden is requested rather than replanting in the original position. A service trench has recently been excavated in close proximity to the base of the existing tree, likely severing a significant proportion of the root system. Replanting in the same location may therefore expose the replacement tree to similar constraints and reduce its long term establishment potential in the future. A replacement tree will be planted in an alternative suitable location within the garden, to be agreed with the Local Planning Authority if required.

6A Midway Walton-On-Thames Surrey KT12 3HYElmbridge

Tree Preservation Order EL:93/13 - A large corkscrew willow. Over time the trunk has become diseased (pictures available) and large chunks have fallen away. The wood left is quite spongy. Will of WG Harpur tree surgeons has visited and proposed that for best recovery and safety (with the weakened trunk) that a major pollard down to a few metres is necessary. That would then be repeated every 3 - 5 years depending on the re-growth and condition of the tree. Apart from the costs involved in the pollarding, we love the tree we would prefer to do nothing to it if some expert could say that it is safe to leave it and it will repair itself. I.E. avoid doing any work on a TPO tree which is normally what Elmbridge prefer. I was hoping that an Elmbridge Tree Officer might offer that independent view but after exchanges / pictures with Carl Springett that does not seem to be an option.
