  1. I have a 300 year old oak tree at the bottom of our garden, which is in excellent health. Our neighbour's insurers have applied to have the tree felled, as they have had a report suggesting that the tree has caused the subsidence, as it has dried out the clay soil. A significant number of local residents objected to the application and the local Council have now issued a preliminary TPO and we are now in the 28 day period where further submissions can be made to the Council, before they decide whether to confirm the TPO. The Council tree officer has valued the tree and will have to convince councillors that the tree is of sufficient value for them to confirm the TPO and risk having to contribute to the costs of alternative solutions. The tree officer fully expects the insurers to object to the TPO. This is all new to me, so can anyone help me with the following questions - 1. HEAVE. The neighbour lives in a semi detached house and the occupants of the other half of the house faced the same issue of cracks when they moved in in 2011. Their insurers ended up concluding that the risk of heave (the oldest houses around the tree were built around 1900, so well after the tree was here) meant that they had to find an alternative to felling the tree. They ended up putting in a 2.5m deep root barrier, which appears to have largely dealt with the subsidence problem. There are 4 1900 era houses close to the tree and the one making the claim is the only one having subsidence issues. None of the houses had any foundations when they were built, but many of the houses, including ours, have had extensions since, which have included some proper foundations. The house making the claim has never had an extension and therefore still does not have any foundations. My question is the Council do not seem to be worried about the risk of heave and the insurer’s report simply says “Heave is not a concern”. Indeed the Council say any submissions we make during the consultation period should address the amenity value of the tree and that there is no point in talking about heave. How can this be right when all of use are concerned about the risk of heave? 2. MEASUREMENT OF MOVEMENT. The monitoring report shows that the largest movement in cracks was 8m, measured between February and August 2020. Is measuring just between a very wet February and a very dry August considered best practice? 3. DRAINAGE INVESTIGATION. The drainage investigation performed seems to have identified some damage to pipework that needs to be repaired. However, the acoustic test to the water main suggested that there weren’t all leaks to that. How is it possible to establish whether any of the leaks involved might be encouraged the root growth from the oak and thereby contributing significantly to the problem? Many thanks in anticipation!

  2. Hello We have gained planning permission for a replacement dwelling with an attached garage. Part of the garage sits within the RPAs of a Lime Tree (T3 - please refer to the attachment) and a series of Beech trees (G7). Please note, trees T1, T2 and T3 are subject to TPOs. Whilst the encroachment has been deemed acceptable by the Council’s Arboriculturist, we are seeking advice on where to navigate the surface water off the main house and garage. Obviously we would want the development to cause as little harm as possible to the Lime Trees, however, it seems as though we have no choice but to place the soakaway(s) within the RPAs of the Lime Trees. The question is then, is it generally acceptable to build soakaways within the RPAs of the Lime Trees? And if the answer is yes, does anyone have any suggestions as to where to place the soakaways for the front of the development? Many thanks Soakaway.pdf
  3. I have recently bought a new house and there is a 15ft Yew outside my house (within the boundaries of my wall). It blocks light and I would like to either: - completely uproot it - trim it to about half the size I have been warned against both for different reasons. Someone told me not to completely remove it because it could cause the land to sink where the roots extend to (Its about 4m away from my front door). Also that the roots are sucking up lots of water which could lead to excess water beneath my house?? Also been told that cutting it back by half would be difficult and it could take years before it goes green again. What would you advise?
