- 5 Malbec Close Harpenden Hertfordshire AL5 4FFAwaiting decisionRemove 30ft cherry tree The approximately 30ft Cherry tree is exhibiting signs of declining vitality, evidenced by a notably sparse canopy during the current growing season. The tree has also developed a pronounced lean towards the client's property, raising concerns regarding its structural condition and potential for failure. In view of its apparent decline, increasing lean and close proximity to the dwelling, removal is considered appropriate to mitigate potential risk and address the tree's deteriorating condition.Received 3 Nov 202626/0566/TCA
- The Stewarts Harpenden Memorial Hospital Carlton Road Harpenden Hertfordshire AL5 4TAAwaiting decisionFelling of 1No. Cherry Tree for the following reasons: Cherry tree is leaning at approximately 45 degrees. There are a number of exposed roots showing historic mower damage and evidence of decay. The tree has a substantial lean and a biased crown towards the building. Whilst a crown reduction could help mitigate the risk, this would require ongoing future management. Removal of the tree would eliminate this risk and allow the surrounding trees to develop in a more upright manner. It is confirmed that the tree is approximately 10-15 metres in height.Received 28 Oct 202626/0542/TCA
