What grading slope is generally preferred for athletic fields according to best practices?

A grading slope of 1-2% is generally preferred for athletic fields based on best practices because this range effectively facilitates drainage, ensuring that water runs off the surface rather than pooling. This is crucial for maintaining a playable surface, preventing mud accumulation, and minimizing the risk of damage to the field due to standing water.

Additionally, a slope within this range allows for optimal grass health by preventing over-saturation, which can lead to root rot and other issues. The 1-2% slope balances the need for drainage with player safety and comfort, reducing the risk of injury due to wet or unstable ground. Overall, this slope is designed to enhance both the usability and longevity of athletic fields.
