How much should the ground surface slope around a building's perimeter within the first ten feet?

The recommended slope for the ground surface around a building's perimeter within the first ten feet is typically 6 inches of fall. This is important because proper drainage is crucial for preventing water damage to the foundation and the structure itself. A slope of 6 inches within the initial ten feet helps direct rainwater and surface runoff away from the foundation, thereby reducing the risk of moisture accumulation, which can lead to issues such as mold, foundation settling, and erosion.

By ensuring that there is a 6-inch drop over this distance, homeowners and builders can effectively manage water flow around their properties. This practice contributes to the overall integrity and longevity of the building, as it minimizes potential water-related problems that could arise if the grading is inadequate. Balancing adequate slope with landscaping considerations is key for both aesthetics and effective water management.
