56 VICARS HILL, LONDON, SE13 7JL
REAR: ONE Oak (T3, TPO T1)(ht.15m) FELL. Reason: subsidence at 56 Vicars Hill, replacement proposed with a standard-sized Silver birch tree.The London Borough of Lewisham (56 Vicars Hill, London SE13 7JL) Tree Preservation Order 2024.Informative A: submitted investigation reports conclude damage appears due to volume change in underlying clay soil which likely started during extreme temperatures summer 2022, other factors include the steeply sloping site, foundations not to current NHBC guidelines, influence of the rear garden oak (T3,TPO T1), nearby works, frequent ground water run-off from the adjacent Hilly Fields which has recently ceased, and comparison of soil moisture with depths at front and rear indicates little change to result in differential movement which could indicate that the TPO oak tree at the rear is not the controlling factor, and alternative to felling the rear oak the damaged structure could be underpinned. Informative B: a heave risk assessment should be carried out before any tree works are undertaken.Informative C: a replacement tree is a condition of the decision notice, (see below) with species to be selected from birch, holly, Gleditsia, hornbeam - from NHBC 4.2.4 low water demand tree list.
