  Works to tree protected by a TPO. We wish to carry out a reduction on this tree of 8m off the top and 3m off each side. It is a Birch tree. The reason for the reduction is that the tree is getting far too large (which is why we asked for its removal) and obscures light into our house and neighbouring residences. We have provided a very simple plan, since the location and everything else about the tree is recorded and clearly shown on the TPO. We attach a photo of the tree.
