The house we are bought has a 100' x 100' back yard. The front portion is
one grade, the rear portion, 2' to 3' higher. A retaining wall with steps
separates the grade. The land has a slight negative pitch toward the house
as the terrain is not level. According to the home inspector, this is a bad
thing because water penetration is more likely.

We intend on removing several trees that exist on the higher grade and
leveling it to that of the lower grade. The knowledge that I'm seeking is
how to level the two grades and create a positive pitch away from the house
when the slope comes towards the home.

Has anyone done this type of work. Can you recommend any web sites that
would be helpful in understanding the process and the costs involved?
