97 Kentish town road/ farrier street

I would like to bring to your attention on the corner parade of Farrier Street there are two London Plane trees, one is quite large and a few years ago pre pandemic you had tree surgeons pollarding this. I spoke with them at the time about the smaller one, I was informed the tree was cracked and rotten and they have already informed Camden council that this needs to be removed. The tree three years later is now excessively leaning towards my property due to, 1. The tree is trying to reach the light coming over the top of my building and 2. The sheer size of the other tree, where the crown of the tree is now touching the middle of the smaller tree. Also, there is a drain in the pavement, I don’t know if the tree roots have grown into the drain and have blocked this or its been blocked due to not being maintained by yourselves. This is now causing a further issue of the area filling up with water and turning the pavement into a lake every time it rains. When Camden council replaced the pavement in the area, they put the slabs up to my building and did not finish the job off with a cemented filet. Now due to this the water is laying there and running down into my basement and causing internal damage to the render and plaster in the basement. I strongly believe that if this tree is not delt with it will fall into my property causing severe damage if we have any strong winds due to the trunk being completely rotten. If this does happen, we will hold yourselves fully responsible for any damages and loss of life. I have enclosed photos of the tree, showing the excessive leaning, the rotten trunk which has also split and a photo of the drain showing the gap between the pavement and the wall. I would appreciate someone coming to assess the damage this has already caused to my property.
