However, the ADA curb cut requirements dictate that curved curbs should have ramps placed so they are perpendicular around corners while still within the crosswalk space.1 The opening of perpendicular curb ramps can be aligned with the curb line or oriented with the crosswalk. Curb ramps are required wherever a sidewalk crosses a curb. E.    What are the General Requirements for Curb Ramps in the ADA Standards for Accessible Design?

A ramp can also overlap with a door opening clearance if the door does not open into the landing area. It is worth noting, both the Department of Justice (DOJ) and Department of Transportation (DOT) have their own requirements regarding the use of detectable tactile warning systems. In 2018, the Department is scheduled to complete an inventory of curb ramps adjacent to State roadways. The goal of the program is to provide accessible facilities for pedestrians with disabilities while allowing local jurisdiction flexibility in meeting the required standards. Intercity and commuter rail stations fall under this designation as well. Appendix A of this booklet is a sample form that may be used to document and publicize the designation The slope must be uniform from one end of the ramp to the other, with a few exceptions for slight variations in the materials used to create the ramp. 4. The gutter is the roadway surface immediately next to the curb ramp that runs along the curb. The federal government has begun a rulemaking process to revise the accessibility requirements for public rights-of-way. For curb ramps, the DOJ and DOT require that raised domes are used in areas that receive funding from the Federal Highway Administration, as well as in federal, state, and local government facilities. www.access-board.gov/prowac/commrept/index.htm.

The curb ramp requirements call for ramps that run parallel to the sidewalk and have landings which are a minimum of 48 inches wide at the base of each ramp.3. Version 1.3 – September 11, 2019. 11 ADA Standards § 4.1.6(3)(a). The ADA limits curb ramp steepness to no greater than 1:12 (an 8.33% slope), a width of 36 inches, and adjacent counter slopes of no steeper than 1:20. The use of tactile raised domes at the top and bottom of ramps is not always required, except when used in public transportation areas, such as subways, train stations, and bus stations. 4.7.3 Width This is particularly important at street intersections, where individuals will interact with traffic.

Another source of information about the federal accessibility requirements for public rights-of-way is the Federal Highway Administration (FHWA) of the U.S. Department of Transportation. A street or sidewalk falls into this category if it was constructed pre-ADA (construction began before January 26, 1992), and has since been altered. If a built-up curb ramp is not feasible and there is limited space to install parallel curb ramps, a different design can be used. Handrail extensions must be at least 12 inches long. In addition, curb ramps and ramps, landings, and the bottom of curb transitions must be designed to prevent the accumulation of water. A detectable warning alerts pedestrians who are blind or have low vision that they need to stop and determine the nature of the hazard – such as whether there is passing traffic – before continuing on their way. A curb ramp is a short ramp cutting through a curb or built up to it.1 If designed and constructed to be accessible, a curb ramp provides an accessible route that people with disabilities can use to safely transition from a roadway to a curbed sidewalk and vice versa. The standards generally represent minimum requirements and include guidelines for the number of accessible parking spaces per parking lot size, dimensions of parking spaces, the design of traffic aisles and curb access, and many other accessibility features. These include increased risks of falling out of a wheelchair or scooter or tripping while using a walker when going over an elevated curb. : PW 1815 The Contractor must have a C-8 or A license.

This is a choice that people with disabilities should not be required to make. If a ramp does not have a level landing at changes in direction, its compounding slopes will not meet ADA curb ramp requirements unless the radius supports a compliant cross slope. The Civil Rights Division recognizes that there will be very rare instances when it will be technically infeasible for a curb ramp installed during alterations to pre-ADA roadways and walkways to be constructed in full and strict compliance with the requirements of ADA Standards § 4.1.6(3)(a) and § 4.7 because of physical or site constraints. What does “altered” mean? One way to make curb ramps compliant with Title II of the ADA is to build them in accordance with the ADA Standards.

In addition, restricting access in public areas under current federal laws could be construed a form of discrimination against such individuals.2.
