What is the recommended slope of a 4-foot sidewalk?

For a 4-foot sidewalk, the recommended slope is typically around 2%, which is a slight grade that helps in drainage without creating an excessively steep surface. This gentle slope aids in directing water away from the sidewalk to prevent pooling and potential slipping hazards while ensuring accessibility for pedestrians, including those with disabilities.

A steeper slope, such as 5% or higher, can become problematic. It can make walking difficult and dangerous due to the increased risk of slipping or falling, particularly for individuals using wheelchairs or mobility aids. As a result, construction guidelines for sidewalks emphasize maintaining a slope that balances effective drainage with safety and accessibility.

Therefore, aiming for a slope of 2% is essential for the proper functionality and safety of sidewalks, making it the most suitable choice in this context.
