What is the minimum distance the grade should drop around a property in the first 10 feet?

The minimum distance the grade should drop around a property in the first 10 feet is typically 6 inches. This guideline is crucial for proper drainage to prevent water from pooling near the foundation of a building. A 6-inch drop within the first 10 feet creates a slope that encourages water runoff away from the structure, which helps to protect the foundation from water damage and minimizes the risk of mold and mildew developing in and around the home.

Proper grading is an essential aspect of landscape design and home construction, as it directly influences the longevity and integrity of the building. Adequate drainage prevents erosion, reduces the potential for flooding in basements or crawl spaces, and maintains the overall health of the landscaping.
