When I moved into this house the lowest place in my front yard was against a bedroom on the NE corner. The area's topo was such that water runoff from 3 houses west of me would drain to that low spot. If it rained very much the vents in that bedroom would start filling with water. Was told I needed to move all my under slab ducts to the ceiling.

Instead I got my trusty roto-tiller out using it an a wheelbarrow and shovel to regrade the front yard. Made it so the ground sloped away from in front of the house sloping across the yard and out to the street. It was a LOT of dirt as my front yard sloped from my neighbors drive to the west down to the front of my house. My back patio was about 8 inches above grade so I used the dirt to raise the grade all across the back of my house to make the grade flush with the patio.

It took me all summer but rainwater does not pool at the front of my house anymore and the vents stay dry as a bone. The only adverse effect is that if it rains very much my water meter cover gets floated off and the meter itself gets covered with mud.

My property still slopes around the house and down from the back of my house to the stockade fence line. I need to re-grade my back yard because the dirt has migrated enough to cover up to the bottom rail of that stockade fence. A new fence was put in with the bottom at ground level about 10 years ago. Figure if it slopes down from the fence towards the back of the house for about 5 or 6 feet, then starts sloping up it will slow the dirt migration enough that the fence will stay above dirt for quite some time.
