Proposal
Works to trees protected by a TPO. T2 Sycamore - Fell and treat stump with eco-plugs 1. The above tree works are proposed as a remedy to the differential foundation movement at the insured property and to ensure the long-term stability of the building. 2. The above tree works are proposed to limit the extent and need for expensive and disruptive engineering repair works at the insured property. In this instance the estimated repair costs are likely to vary between £20,000 and £150,000, depending upon whether the tree/s can be removed or must remain. 3. The above tree works are proposed to limit the extent and need for costly CO2e emissions relating to alternative engineering repair works at the insured property. A typical underpinning scheme can include a carbon cost of more than 6000 kg CO2e and soil stabilisation or root barriers more than 4000 kg CO2e. A typical tree might capture between 15-40kg CO2e per annum and would therefore take centuries to mitigate the cost in CO2e on any alternative. We also confirm that the applicant has included this scheme and application in its tree planting and carbon capture off-set scheme for trees causing subsidence to low rise buildings which has already seen some 11,000 trees planted and additionally 220 tonnes of carbon captured. 4. The above tree works are proposed to limit the duration of any claim period and therefore allow the landowner their right to the peaceful enjoyment of their property. 5. It is the case that an alternative to felling such as pruning or significant ‘pollarding’ of the tree would not provide a reliable or sustainable remedy to the subsidence in this case. We do not consider that any other potential means of mitigation, including root barriers, would be effective or appropriate in the circumstances. 6. We are satisfied that the evidence obtained following completion of our Arboricultural Implication Assessment report completed 20/01/2023 clearly links the Sycamore T2 as a cause of damage to the risk address. 7. Insurers understanding the requirement to offer replacement planting in the event consent to fell is granted.

Five Day Notice. The tree is located on the roadside boundary of 45b shepherds hill, Highgate, London, n65qj. The tree in question is a Sycamore tree showing extensive deadwood and historical damage at the base. The tree due to its location adjacent to the footpath and main road I believe posses a risk to third party members of the public. If I thought there was a chance of the tree living I would suggest a heavy reduction/pollard but as the photos show the die back is extensive. I am asking for permission to fell the tree to ground level.

T1 - Ash - Crown reduction by 3m in height bringing lateral growth to shape by 1.5m. Removal of all major dead wood, leaving the tree a standing height of 9m. Reducing the crown by approximately 3 meters in height and 1.5 meters laterally will help reduce overall crown weight and wind loading, while maintaining a balanced and proportionate crown.
