  T1 Holm Oak - this tree, growing in the border of Morden Road Mews (to the rear of no.6 The Keep), requires pruning to manage its size for the residents of the garden over which it grows. It has been pruned on the road side, to allow bin lorries etc to pass freely, but has been allowed to overextend the garden quite considerably. As well as lifting the canopy by removing the lowest few branches over the boundary fence (to enable the owners to replace / repair structures in the back of the garden), we're applying to reduce the radial spread over the garden (of no.6 The Keep) by 2m from 5m to 3m to match the roadside and a reduction in height by 3m from 7m to 4m and shape accordingly.

Cut back from street light to give 1m clearance. Soft Maple (T9 on Survey) - Reduce to old points. Reduce height by 4m from 12m to 8m and radial spread by 3m from 6m to 3m all round.
