  • P26/S0863/TPO Granted

    Chiltern House, 5 Plowden Park, Aston Rowant, OX49 5SX

    T1 Weeping willow Observations: T1 is a mature weeping willow. On 12/03/26, T1 shed a substantial limb, which narrowly missed a worker on site. Following this, a medium sized branch remained hanging in the canopy and was partially attached. This posed an immediate safety hazard and had the potential to cause injury or damage if it were to fall. We then conducted emergency works 13/03/26. RETROSPECTIVE TPO APPLICATION: 13/03/26 - SBTS email to Planning South - [email protected] 'Good afternoon, We have been called to a residential emergency today at - Chiltern House, 5 Plowden Park, Aston Rowant, OX49 5SX. There is a mature TPO weeping willow on the front boundary which, in yesterday's high wind speeds, has had a significant limb fail. As it stands, another limb has snapped and is currently barely hanging on and will drop at any given moment - see photos attached. This is a kind notification of intent to undergo emergency works, due to the urgent nature of these limb failures. A primary school is located very nearby, which compounds the urgency of these works as a matter of health and safety. We will be attending the property this afternoon to make the tree safe. Any further recommended works will of course be submitted in a planning application. Kindest regards, Estella' Further Observations: A ground level inspection of the tree indicates that it otherwise appears to be in generally healthy condition. There are no visible signs of decay or fungus, and no structural defects present. Following the removal of the hanging branch, a crown reduction of approximately 5 meters is proposed in order to reduce the canopy weight, helping to minimise any further limb failure. The location being near a primary school must be taken into consideration. Recommendations: Crown Reduction - Reducing the height and spread of the tree by up to 5 metres.
