Which of the following is true about ramp design in ADA compliance?

• A. All ramps must have a maximum rise greater than 48 inches
• B. Ramps must not exceed a rise of 30 inches
• C. Ramps can have maximum slopes of 3%
• D. Ramps should be designed for aesthetic appeal only

Answer: (B)

For ramp design in compliance with the Americans with Disabilities Act (ADA), it is essential to ensure that ramps are accessible and safe for individuals with disabilities. The correct statement regarding ramp design is that ramps must not exceed a rise of 30 inches. This requirement is guided by the ADA Accessibility Guidelines, which specify that if the vertical rise of the ramp is greater than 30 inches, specific design modifications and landings must be implemented to facilitate safe usage and to provide clearance, thus enhancing accessibility.

Ramps designed with a rise greater than 30 inches would require additional safety features, including landings that can accommodate users and prevent falls. This limit is crucial in ensuring that the ramps are navigable and do not pose a risk to the users.

The other considerations in this question highlight different aspects of ramp design, but they do not align with ADA standards. For example, having a maximum rise greater than 48 inches is not compliant with the guidelines and poses significant safety issues. Furthermore, the maximum allowable slope for ramps per the ADA is typically 1:12 (approximately 8.33%), which is much steeper than the 3% slope mentioned, making that option misleading. Lastly, focusing solely on aesthetic appeal does not account for the essential functional
