The top of any exterior foundation on grade sites must extend above the elevation of the street gutter at the point of discharge to ensure proper drainage and to prevent water from accumulating against the foundation. This requirement is crucial because if the foundation is lower than the street gutter, rainwater flowing from the street could lead to water pooling around the foundation, which might cause water damage or destabilize the structure over time.

By setting the foundation height above the street gutter at the point of discharge, it minimizes the risk of moisture intrusion and promotes effective water runoff away from the property. This practice aligns with building codes and standards that aim to safeguard the longevity and structural integrity of buildings in areas prone to heavy rainfall or flooding. Proper grading also helps manage water flow, ensuring that it is directed away from the foundation, further protecting against potential water-related issues.
