Most of the grading was done south of the final impact. Also, the house existed before then as well as the hill across the street where the trees were initially hit. Assuming the old topo is reasonably accurate, then that gives us a an approximate benchmark. Even if you say a +- of 40 feet then you can still start to draw some conclusions...
