They also might have slower reaction times and slower walking speeds. Any slopes below the 1.5% minimum should be amended to facilitate a safe crossing. Depending on the state or specific site, there may be more requirements such as at a senior home, physical therapy, or large hospital parking lot. The Basics: The ADA has strict requirements for sidewalks to ensure theyre safe for people affected by disabilities. A non-compliant sidewalk can create severe safety risks for pedestrians with limited mobility, impaired vision, or any other form of disability.
