The best way to keep any structure dry is to keep water from coming in contact with it. To move water away from the home, each site plan should include a drainage plan for the finished residence. The finished grade around the perimeter of the structure should fall away from the dwelling at a minimum slope of 6 inches for the first 6 feet. After 6 feet the slope can be reduced to a minimum of 2 feet for every 100 feet.

Installing gutters, downspouts and splash blocks that direct rainwater away from the residence helps control the removal of rainwater. A good overall landscaping plan helps eliminate the possibility that water will be trapped near foundation.
