    To reduce the hornbeam by 40%. The hornbeam is situated to the side rear of the property on the boundary with the WHC Allotments. The tree is approx 15m in height with approx 9m crown spread. The tree has been maintained as a high pollard. Proposed works will reduce the crown back to previous reduction points to continue maintenance. This was last done in 2014. These works would not negatively affect the character or amenity value of the landscape. This work would help maintain the tree, reduce overhang into the allotment and increase light

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 Pending, withdrawn and unknown outcomes are excluded.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.
