    TPO 806 (2018) T2 Tree 48 on the Terrain Survey plan. AAA tree report dated 10th June 2024, which states that the cedar tree Tree 1 in the report is dying and requires total removal. The cedar tree is in close proximity to several properties which could become endangered due to branch fall or total collapse. The residents pass close to the cedar tree to access the parking area which is situated at the north end of the site. There is a high risk to health and safety. We would want to replace the tree with a similar species for future residents

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 Pending, withdrawn and unknown outcomes are excluded.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.
