  Front Garden: T1 and T2 Lime. Re pollard to previous pollard points and remove lower growth. Council Note: Previous TCA history noted for repeat management of the two front garden Lime trees including re pollarding in 2001 2019 and 2022.

  T1 & T2 Willow (Salix spp.) RE-POLLARD: remove the snapped limb and reduce regrowth by 3 to 4m in height and 2 to 3m laterally, back to established pollard points, retaining the existing framework and balanced crowns. Reason: cyclical management following substantial regrowth and limb failure; to reduce end weight and risk of further failure while retaining amenity value. T3 Mimosa (Albizia julibrissin) CROWN REDUCE height by 2m to 8m and radial spread by 2m to 6m. Remove dead and declining branches and reshape to form a balanced crown. Reason: canopy decline, dieback, poor form and excessive end weight; to reduce loading on weakened limbs, improve structure and prolong useful life. T4 / TPO 43 T13 Holm Oak (Quercus ilex) CROWN REDUCE height by 2m to 10m and radial spread by 2m to 8m. CROWN LIFT over the adjacent highway to 5.5m above ground level. Reason: to maintain the tree at an appropriate size, improve light and highway clearance, reduce future management and retain a balanced, healthy crown. All works to BS3998:2010 Tree Work Recommendations.
