On graded sites, the top of exterior foundation must extend above the elevation of what at the discharge point?

• A. street gutter
• B. finished grade
• C. roofline
• D. property line

Answer: (A)

The correct answer is that the top of the exterior foundation must extend above the elevation of the street gutter at the discharge point. This requirement is essential for proper drainage and to prevent water from pooling around the foundation. When the foundation is set higher than the street gutter, it allows for effective water runoff and minimizes the risk of water intrusion or flooding in the basement or foundation area. In terms of safety and building codes, ensuring that the foundation is elevated above the street gutter helps protect the structure from water-related issues. Streets typically act as channels for stormwater runoff; thus, having the foundation above this level helps ensure that water flows away from the residence rather than towards it. Other options such as finished grade, roofline, and property line may influence site design but do not specifically address the immediate concerns related to drainage in relation to street gutters. The finished grade refers to the final surface elevation of the land, while the roofline relates to height considerations of the building itself, and the property line pertains to boundaries rather than drainage requirements.
