A lot shall be graded to drain surface water away from foundation walls for a minimum of how many feet?

• A. 5 feet
• B. 10 feet
• C. 15 feet
• D. 20 feet

Answer: (B)

The correct answer indicates that grading should slope away from the foundation walls for a minimum of 10 feet. This is vital for preventing water accumulation near the foundation, which can lead to serious structural issues such as foundation settling, cracking, and even mold growth due to water infiltration. Proper grading ensures that surface water is effectively directed away from the foundation area, minimizing the risk of water-related damage. In construction and landscaping practices, the general guideline of 10 feet allows for adequate drainage that can handle common rainfall and surface runoff. While greater distances can sometimes offer additional safety, the 10-foot requirement is often regarded as a standard to ensure effective prevention of water pooling near building foundations.
