Final cuts to be made at suitable pruning points, leaving furnishing growth to minimise visual impact.

    T176 - Prunus cerasifera: Reduce crown by specified extent - reducing the extended limbs to the southeast over the road and parking by approximately 2 m to reduce the overhang back to the carriageway side edge of the parking bay to clear the highway and reduce loading on the historically cracked basal fork. Also lift the canopy over the car parking bay to 3 m to provide sufficient clearance for vehicles. Final cuts to be made at suitable pruning points, leaving furnishing growth where possible. T177 - Platanus x hispanica: End weight reduction - reducing the two braced stems (to the north and to the west), and reducing the lateral limbs to the east and southeast, by 2-3 m, back to the most recent previous reduction points. This work should be carried out prior to the replacement of the cable braces. T181 - Prunus cerasifera: Lift low canopy, pedestrian clearance - to 2.5 m over garden footpath. T184 - Pyrus salicifolia, T187 & T100161 - Prunus cerasifera: Lift low canopy, specified extent - to 3 m over car parking. T100276 - Halesia carolina: Fell ground level - dead young planted tree grubbing out root ball to facilitate replanting. Plant replacement tree - (Halesia carolina) during the first planting season (September to April) following tree removal.

    Lords Cricket Ground St John's Wood Road London NW8 8QZ

    2 lime trees located to the west of the Allen Stand and north of Lords Tavern, by the Grace Gate entrance from St John's Wood Road. These trees are noted as T7 and T8 on attached plans and reports. Roots belonging to both trees were severed during excavations for service trenches associated with construction of the Allen Stand on site. Static load tests were carried out to both trees in April 2026, which flagged T7 as having an insufficient safety factor. T7 was therefore recommended for a 3m reduction in height to reduce the risk of failure. Due to T7 and T8 forming a continuous canopy, T8 has also been recommended for the same specification of reduction to prevent exposing its crown to excessive wind loading.

    208 Randolph Avenue London W9 1PF

    T3 ? Sycamore (Acer pseudoplatanus), located in the rear garden of 208 Randolph Avenue, London W9 1PF. Proposed works: Fell T3 Sycamore to ground level and remove the resulting timber and arisings. The tree has been classified as Category U in the Arboricultural Implications Assessment (Report J69.34, dated 12 October 2026) prepared by Broad Oak Tree Consultants. The assessment identifies significant basal decay, a basal cavity, structural deterioration and crown dieback. The report recommends pollarding at approximately 8 metres or felling. Full removal is proposed due to the tree's poor structural condition and associated safety concerns.
