The proposed works relate to the mature London Plane tree located in the rear garden. There is currently some deadwood within the lower canopy, and small branches have been falling into the garden, creating a potential safety concern. The proposed works are intentionally limited and precautionary. We are not proposing any crown reduction, topping or removal of established structural limbs The works will consist only of removing clearly dead or unsafe minor branches where necessary and removing epicormic growth from the lower part of the tree and main stems The overall height, spread, shape and main crown of the tree will remain unchanged All significant healthy branches and the upper canopy will be retained The intention is simply to improve safety and manage the lower growth while preserving the character, health and appearance of this mature London Plane All works will be undertaken carefully by a professional tree surgeon and in accordance with appropriate arboricultural practice

23 Shepherds Hill, Hornsey, London, N6 5QJ

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.

1 x Ash tree – Reduce the overall crown by approximately 20–30%, equating to around 2–3 metres, pruning back to suitable growth points while retaining a balanced and natural canopy shape. Remove any dead, damaged or crossing branches as necessary. All works are to be carried out in accordance with BS 3998:2010 – Tree Work Recommendations. Justification The tree has become excessively large for its position and is significantly restricting natural light into the property. The proposed crown reduction will reduce the overall size and spread of the canopy, improve light penetration and manage the tree at a suitable scale for its location, while retaining its long-term health, structure and amenity value.

9 Southwood Mansions, Southwood Lane, Hornsey, London, N6 5SZ

Front garden: fig (T1) - fell. Reason: An initial assessment (not a full arboricultual survey) indicates the tree is the likely cause of cracking in the pavement. The roots will continue to expand and so cracking will likely continue to worsen. Pruning will not significantly reduce damage over the medium term. The cracking can be seen extending towards the building. The tree is located around 2m from the building. British Geology Survey maps show the property sited on Claygate member clay which is not as shrinkable as London clay but is still considered to have medium to high shrinkability. This could be confirmed through lab soil tests. Considering the period of the building, the foundations are likely to be shallow strip foundations. This could be confirmed through exploratory digging.
