Proposal

London planes (T1 & T2) - Reduce crowns back to previous cuts (approx 2m off). Raise crowns to 5m over the road and 3m over the pavement. Reason: To restrict root growth and let more light into the embassy. Remove branches infected with Massaria (up to 10cm diameter).

T2 Prunus sp.- Fell As above , in addition the trees lower branches have been removed and now has impaired form, is being suppressed by the London Plane tree and it has very few blossoms in the spring. If nessessary the tree owner would be prepared to replace the two trees with a more suitable tree
