We will be building a house and have to remove some sand and dirt from underneath the house. We were thinking of using this material on site instead of hauling it away. A corner of our lot is lower than the rest and the initial thought was to raise the ground level there. There´s also a deep and wide ditch on the edge of our lot, which could be made narrower. The ditch could take in a large amount, so that´s useful.
However, there´s two big trees on the edge of the ditch in the low corner. (See the attachment.) In the foreground is a Birch, in the back a Pine. This is in Finland, so I guess: Betula pendula and Pinus sylvestris. The ground is moderately sloping towards the ditch and the slope in the ditch right next to the trees is quite severe. Depth of the ditch is more than a meter.
The questions are:
1. How much can the ground level be raised for these trees to remain healthy?
2. How much can you fill the ditch?
3. If the trees can´t handle it, how large of an area would need to be kept intact for them?
I suppose we could remove these trees and plant new ones, but I´d rather save these!
Thanks in advance!
