The current building standards require a minimum fall in ground level of how many inches over a distance of 10 feet from the perimeter of the building?

The current building standards stipulate that there should be a minimum fall in ground level of 6 inches over a distance of 10 feet from the perimeter of the building to ensure proper drainage away from the structure. This slope is critical as it helps prevent water from pooling around the foundation, which can lead to moisture penetration and potential structural damage. Adequate drainage is essential for protecting both the foundation and the overall integrity of the building, fostering a dry area that mitigates the risk of soil erosion and water-related issues. This standard is designed to promote effective water management around buildings, which is why the 6 inches over 10 feet is the accepted guideline.
