    Tree "T1" in the attached diagram is a Horse Chestnut located at the southern edge of the rear garden. It appears to have been pollarded at about 2m in height but since then it has just been left to grow and is now very overgrown. As part of ongoing garden maintenance, my proposal is to use a combination of crown thinning (by 30%) and crown reduction (to a height of 6m and a spread 4.5m) to restore some shape to the tree.

What these statistics cover

These figures describe applications collected by PlanningTrack for Three Rivers District 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 Pending, withdrawn and unknown outcomes are excluded.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.
