Ensuring Accessibility: ADA Standards for Ramps

Ensuring Accessibility: ADA Standards for Ramps

Creating accessible spaces is a cornerstone of the 2010 ADA Standards for Accessible Design, especially when it comes to ramps. Ramps play a critical role in allowing individuals with mobility impairments to navigate changes in elevation within buildings and around facilities. In this blog, we’ll explore the ADA requirements for ramps, including essential measurements, design considerations, and examples of how to ensure compliance.

Why Are Ramps Essential?

Ramps provide a safe, usable route for people using wheelchairs, scooters, walkers, or for those who find stairs challenging. Compliance with the ADA Standards ensures that ramps are not just present but also usable and safe for everyone. Under the ADA, all new construction and significant alterations must incorporate ramps where changes in elevation are part of the path of travel.

Key ADA Requirements for Ramps

According to the 2010 ADA Standards, ramps must meet specific criteria regarding slope, width, and landings to ensure accessibility:

1. Slope and Rise:

   • Ramps must have a slope no steeper than 1:12, meaning for every inch of vertical rise, there must be 12 inches (one foot) of ramp length. This requirement ensures that the incline is manageable for wheelchair users and individuals with other mobility devices.

   • The maximum allowable rise for any run of ramp is 30 inches (2010 ADA Standards, Section 405.2).

2. Width:

   • The minimum width of a ramp should be 36 inches (clear width) to accommodate a wide range of mobility aids (2010 ADA Standards, Section 405.5).

   • If handrails are required on both sides of the ramp, these handrails should not reduce the minimum width of 36 inches between them.

3. Landings:

   • Landings are required at the top and bottom of each ramp run. The landing must be at least as wide as the ramp itself and have a minimum length of 60 inches (2010 ADA Standards, Section 405.7).

   • When ramps change direction, the landing must provide enough room for users to maneuver. In cases where a 90-degree turn is required, the landing should be a minimum of 60 by 60 inches.

4. Handrails:

   • Ramps that rise more than 6 inches must have handrails on both sides. The handrails should be between 34 and 38 inches high, measured from the ramp surface to the top of the handrail (2010 ADA Standards, Section 505.4).

   • Handrails should extend at least 12 inches beyond the top and bottom of the ramp, providing additional stability as users approach and exit the ramp.

Common Ramp Applications and Examples

Example 1: Entrance Ramps for Public Buildings

In new commercial construction, entrance ramps are often necessary where stairs are present. For example, a medical clinic with a five-step entrance needs a ramp to provide accessible entry. With each step approximately 6 inches high, the total rise is 30 inches, meaning the ramp length should be at least 30 feet (30 inches x 12 inches per rise).

Example 2: Ramps for Parking Access

Facilities must ensure that accessible parking spaces have a compliant route to the building entrance. In cases where a ramp is required to connect the parking area to a walkway, it should have a slope that does not exceed the 1:12 ratio. Additionally, it’s important to consider landings at the start and end of the ramp where the parking area connects with the accessible route to the building.

Additional Design Considerations

• Surface Textures: Ramp surfaces should be slip-resistant and designed to avoid any potential hazards. Smooth, non-slip materials help ensure safety in both wet and dry conditions (2010 ADA Standards, Section 405.4).

• Cross Slopes and Edge Protection: The cross slope (side-to-side angle) of ramps should not exceed 1:48, and edge protection should be installed when there is a drop-off on the side of the ramp to prevent wheels from slipping off (2010 ADA Standards, Section 405.3 and 405.9).

Conclusion

Ramps are essential for ensuring accessibility in buildings and facilities, and following the ADA standards is crucial in providing safe, usable spaces for everyone. From the slope and handrail requirements to width and landing specifications, the 2010 ADA Standards provide a comprehensive framework for designing compliant ramps. By adhering to these guidelines, businesses and organizations can promote inclusivity, improve accessibility, and avoid potential ADA violations.
