Proposal
TPO 24 T2 - 1 x Oak to remove in sections to ground level. Tree is suppressed by neighbouring tree leaving a high canopy, blocking lights to neighbouring gardens as part of a larger group **a reduction doesnt seem suitable due to the existing canopy shape. Reducing the tree significantly will create a denser thicker poorly attached growth. Client happy to replant T3 - 1 x Beech tree to reduce overhanging lateral branches by approximately 2m. Reduce lateral overhang to no 16 as tree is too close to boundary and excessive overhang is leaving bird poo on kids play equipment… Data via plota.co.uk
