  18. Decided6/2025/1605/TC

    T1 - Cherry Tree - Reduce Crown by 30%: It has been 3 years since this same reduction took place and the tree has become overgrown in the interim period T2 - Cherry Tree - Remove: We believe this tree is an off-shoot of the main cherry tree - it is poorly formed and has begun to become dangerous, with a large branch coming off recently in high winds - needs removing for safety T3 - Mixed Hedge - Remove - this is formed of 2 Leyland Cypress trees, mixed in and overgrown with 1 poorly formed and aged / damaged apple tree and 3 aged holly trees. As well as being poorly formed, it has become disproportionate in size to the garden - particularly given the size of the main cherry tree and line of mature trees and hedge running along the right flank of the garden, adjacent to The Valley Green. We intend to replace with a more suitable and proportionate hedgerow

These figures describe applications collected by PlanningTrack for Welwyn Hatfield Borough Council, across all dates currently available. They are a partial dataset, rather than an authority-wide performance measure. The date range does not establish continuous historical coverage.
