Hi all I also need some advice on a similar topic- a planning permission has been granted for the structure to be built near a ash tree using piled solution- the floor level is approx 600mm lower then the rear garden, hence the ground must be lowered to achieve a level floor. The planning drawings show a level floor on plans and elevations which have been granted. The tree report states not to lower the ground. the contractor has dug down to the correct level to install the piled raft. The RPA witching the did is approx 8%, and only 3-4 roots were encountered. the conditions in the planning contradict each other - one condition states to follow the tree report which states do not lower ground level. And another states to match the approved drawing which clearly shows the the ground being lowered. as stated the contractor has already done the dig. I don’t think the tree will be affected as in my research I have read maximum 20% root area can be damaged without damaging the tree, in this case it’s approx 8%. I’m just not sure what the penalty is on a case like this, your help will be much appreciated
