Planning Application Details

I would like to cut down the two oak trees (T1 and T2) that are now much too big for the garden in order to prevent significant changes in the ground and damaging the property. I am willing to plant two other tree elsewhere - perhaps with Surrey Heath's tree planting initiative - but the plot isn't large enough to plant replacement trees that won't interfere with the property. One of the trees (T2) grows precariously right on the edge of a ditch and we previously had permissions to fell it.
