What is the maximum slope allowed on a finished grade?

• A. 25%
• B. 40%
• C. 50%
• D. 60%

Answer: (C)

The concept of maximum slope on a finished grade is essential for ensuring stability, safety, and proper drainage in construction and landscaping projects. A 50% slope means that for every 1 unit of horizontal distance, there is a 0.5 unit rise (or fall), which can be steep enough to pose risks of erosion or instability but still within acceptable limits for certain applications. This level of slope can be found in situations where grading needs to accommodate various landscaping requirements or when constructing access roads that manage to remain functional and safe under challenging conditions. It is critical to ensure that the slope is not excessively steep, as this can lead to various issues such as groundwater runoff, soil erosion, and potential landslides. When considering options that go beyond 50%, such as a 60% slope, these can often exceed safety and stability guidelines for most common applications. Thus, the 50% slope stands as a practical maximum for specific scenarios, given that it balances feasibility and risk while still being manageable for various engineering practices.
