  10. Decided6/2025/0551/TC

    T1 is a tall fir tree in the rear garden. My client in the neighbouring garden Has commenced work on their extension and this tree due to its height at over 20 meters tall poses significant risk to the property if it were to fall. It is all but impossible to carry out a quality reduction of this tree to a safe height so removal is preferred. T2 is a conifer at the front of the property standing at 13 meters tall. Its right on the edge of the pavement. We wish to reduce this by 2 meters in height and shape the top so its not a flat top. This is being reduced as maintenance to minimise the risk of the tree falling over on any parked cars or across the pavement.

What these statistics cover

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.

The approval percentage is approved records divided by approved plus refused records. Pending, withdrawn and unknown outcomes are excluded. No percentage is shown until there is an approved or refused record.
