What is the minimum cross slope allowed for ramps?

• A. 0.5%
• B. 1.0%
• C. 1.5%
• D. 2.0%

Answer: (B)

The minimum cross slope allowed for ramps is significant for ensuring accessibility and safety for users, particularly for those with mobility impairments. A cross slope of 1.0% is often specified because it provides sufficient drainage for surface water while being gentle enough for individuals using wheelchairs or other mobility devices. This slope allows for effective water runoff without creating a hazardous condition for users who might struggle to navigate steeper slopes. If the cross slope were too steep, it could lead to difficulties in maneuvering, increasing the risk of tipping or losing control, especially in wet conditions. Furthermore, adherence to this standard helps ensure compliance with building codes and accessibility guidelines, such as the Americans with Disabilities Act (ADA), which aims to make public spaces usable for everyone. Other options either fall below this standard or exceed the maximum recommended cross slope, compromising accessibility and potentially leading to unsafe conditions.
