As of 2020, the ADA requirements for curb cut dimensions are as follows: Clearance Width – if handrails are used (or required), there must be a minimum clearance of 36 inches in between the leading edges of the handrails Rise – the ramp cannot rise greater than 30 inches per run (a run is from base to top of a ramp) As long as a curb ramp or ramp doesn’t exceed 30 inches in height, there are no restrictions on length. SIDEWALK WIDTH Sidewalk width requirements are especially important for wheelchair-bound individuals. : PW 1815 The Contractor must have a C-8 or A license. [§ 4.7.5; Fig. When an accessible route crosses a curb, it requires a “curb ramp”. Appendix A of this booklet is a sample form that may be used to document and publicize the designation [§ 4.1.6(3)(a)(ii)], The cross slope of the ramp run itself may not exceed 2 percent (1:50). What are curb ramps and what function do they serve? Curb Ramp Construction 2019 Module A. ADA Removal Limits 2 The Contractor and the Engineer shall work together to construct all pedestrian facilities to meet the requirements set forth in the plans. [§ 4.3.7], The ramp, or ramp run, must be at least 36 inches wide, not including the flared sides. Curb ramps are a small but important part of making sidewalks, street crossings, and the other pedestrian routes that make up the public right-of-way accessible to people with disabilities. However, the ramp must still transition at the bottom into the street inside the marked crossings for both crosswalks. To comply with ADA requirements, the curb ramps provided must meet specific standards for width, slope, cross slope, placement, and other features.3 In constructing facilities such as walkways and pedestrian crossings, state and local governments can choose between two sets of standards – the ADA Standards for Accessible Design (ADA Standards) and the Uniform Federal Accessibility Standards (UFAS).4 Both of these standards have been deemed to comply with the requirements of Title II.5 However, state and local governments cannot pick and choose between particular portions of the ADA Standards and UFAS as they construct or alter the pedestrian crossings on a street and the curb ramps that provide access to the adjacent sidewalks. The new guidelines will cover pedestrian access to sidewalks and streets, including crosswalks, curb ramps, street furnishings, pedestrian signals, parking, and other parts of the public right-of-way. determine the extent to which it complies with ADA accessibility requirements. These are perfectly acceptable alternatives in locations such as parking lots. The gutter is the roadway surface immediately next to the curb ramp that runs along the curb. www.fhwa.dot.gov/civilrights/ada_memo_clarificationa.htm, www.fhwa.dot.gov/environment/bikeped/prwaa.htm, www.fhwa.dot.gov/environment/bikeped/dwm.htm, www.access-board.gov/ufas/ufas-html/ufas.htm. The handrail detail is the same as the first example with a bottom rail no more than 27 inches (305 mm) above the ramp and landings. The different parts of the most common type of curb ramp, a perpendicular curb ramp, are labeled in the illustration below. The parking garage that serves the town hall is located on North Street, directly across the street from the town hall’s accessible entrance. compliance with these requirements. Detectable warnings are intended to function much like stop signs for pedestrians who are blind or have low vision. © Copyright - ADA Solutions All rights reserved. They can be cut through or built up to the curb. Transitions between the ramp and the sidewalk, gutter and street are located at the top and bottom of the ramp run. The goal of the program is to provide accessible facilities for pedestrians with disabilities while allowing local jurisdiction flexibility in meeting the required standards. Side flares are included to reduce the risk of tripping. The ramp section of a curb ramp is also known as the “ramp run.” If the curb ramp has flared sides, which can also be seen in the illustration to the right, do not include them in the measurement. 15 DOT’s memorandum encouraging use of this alternate design for detectable warnings is The Advisory Committee’s report is available on the Access Board’s website at www.access-board.gov/prowac/commrept/index.htm. Ramp runs shall have a running slope not steeper than 1:12 (8.33%). Now that you know some of the basic ADA requirements for providing curb Liquidated damages $2,100 per calendar day. to track new curb ramps and upgrades of existing curb ramps in 2019. Although any ADA guidelines developed by the Access Board will not be enforceable under Title II of the ADA until the Department of Justice and the U.S. Department of Transportation issue regulations adopting them as standards, the Access Board’s website provides information discussing accessibility concerns relating to curb ramps, sidewalks, pedestrian crossings, and other pedestrian routes. after they are built by private developers and deeded over to the public public entities also receive the legal responsibility for installing ADA-compliant 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. survey form for use in conducting your surveys. What does Title II of the ADA require with respect to curb ramps at pedestrian crossings? This is a choice that people with disabilities should not be required to make. For ADA compliance, the minimum sidewalk width is 36 inches (3 feet), though sidewalks can be wider. The only exception is where work area equipment that’s essential to the work being performed is used.1. The best way to determine if a curb ramp is accessible is to survey it to The City worked with CREEC and Linda Dardarian (Goldstein, Borgen, Dardarian & Ho) to obtain a Settlement Agreement for constructing or remediating 1500 curb ramps per year over the next twelve years (2019-2030), along with other ADA efforts, to make Portland a most accessible City. Generally, you must provide curb ramps wherever a sidewalk or other pedestrian walkway crosses a curb. Therefore, it is always imperative to reference the code, 2010 ADA Standards for Accessible Design, when designing a ramp for new buildings or renovations to existing buildings. public entities to provide. If the landing is at least 36 inches long, it has enough room for a person using a wheelchair to approach the ramp, exit, or turn without crossing over to the flared side’s compound slope. If curb ramps are not provided, these individuals are forced to make a difficult choice. If curb ramp flares are used, they cannot be steeper than 1:10. information needed to answer each question on the survey form. If the height of a ramp at its highest point exceeds 30 inches, it can be installed as several smaller ramps. § 35.151(b). Crossings do not have to be marked, and there are no standards for how they should be marked. The slope shall be measured as shown in. Curb ramps are required for newly built and altered streets, roads, and intersections or anywhere there are curbs or other barriers from the street to a pedestrian walkway. ADA Ramp Handrails When a handicap ramp has a rise greater than six inches or a horizontal projection greater than 72 inches, the ramp must have handrails on both sides. The regulation implementing title II of the ADA was revised as recently as 2016. They must be at least 48 inches long with 24-inch-long segments on either side beyond the flares. 7 The bracketed references in this section refer to the applicable sections of the ADA Standards The workshop will include a brief overview of the Americans with Disabilities Act (ADA), Federal Highway Administration (FHWA) requirements, NJDOT requirements, AASHTO “Green Book” requirements, group exercise designing curb ramps, and video presentations by the United States Access Board to provide the attendees with background information and points-of-view of persons with … § 35.151(a). [§ 4.7.2], Many sidewalks and roads become the responsibility of public entities Just knowing the ADA requirements is not enough to guarantee that your homemade ramp will be safe. “Alterations” are another category of construction under the ADA. Under the ADA Standards, curb ramps are required to have detectable warnings that extend the full width and depth of the curb ramp.14 An example of a perpendicular curb ramp that complies with this requirement can be seen to the left. Built-up curb ramps are ramps that are added off a curb to allow for access. These include increased risks of falling out of a wheelchair or scooter or tripping while using a walker when going over an elevated curb. This eliminates an ADA curb cut and can be used to reduce the speed of traffic. A ramp can be temporary or portable only if it serves a temporary structure. The combined curb ramp breaks the elevation change between the curb and the street into two parts, and uses a separate ramp to bridge each part: a parallel ramp from the sidewalk to a level landing, and a perpendicular ramp from the level landing to the roadway. Under a more flexible standard called “program access,” alternative routes to buildings may be acceptable where people with disabilities must travel only a marginally longer route than the general public. Resurfacing a roadway beyond normal maintenance is an alteration.

Some facilities may benefit from other measures such as speed bumps, reduced traffic speeds, marked crossings, and other options. The town should seek input from people with mobility disabilities regarding the other key locations where curb ramps need to be installed to provide program access. Only one of these two standards may be used for a particular facility. The details are reported in accordance with Section 8 of the Agreement on pages 15-16 of ODOT’s Annual Report. Section 5. ramps at pedestrian crossings, you can assess whether your entity is in In case of an overlap, it’s highly recommended for the door to swing open in the direction opposite the landing. D.    What Does Title II of the ADA Require with Respect to Curb Ramps at Pedestrian Crossings? But. Most commercial construction projects must meet the parking standards outlined by the Americans with Disabilities Act (ADA). However, they are not necessarily required to do so. These … However, ramp runs with greater slopes are allowed for pre-ADA curb ramps in the two following instances where space limitations prohibit the use of a slope of 8.33 percent (1:12) or less: The ramp run may have a running slope of up to 10 percent (1:10) if the rise is no more than six inches. F.    What are Pedestrian Crossings and Where Must Curb Ramps be Provided? Transitions from ramps to walks, gutters, or streets shall be flush and free of abrupt changes. Landings shall be provided at the tops of curb ramps. In the construction or alteration of roadways and walkways, this typically means that only one standard may be used for a particular construction or alteration project, and all features of that project typically must comply with the chosen standard. It is also … Consider a case where the streets and sidewalks in a small town were built pre-ADA and have not been altered since. But they are just one part. The History and Evolution of Detectable Warning Surfaces, The ADA curb ramp slope standards require the slope, sidewalks used by people with vision impairments, https://www.access-board.gov/guidelines-and-standards/buildings-and-sites/about-the-ada-standards/guide-to-the-ada-standards/chapter-4-ramps-and-curb-ramps, https://www.ada.gov/pcatoolkit/chap6toolkit.htm, https://www.ada.gov/regs2010/titleII_2010/titleII_2010_regulations.htm#subpartd, The Process of Installing Transit Surface Applied Tactile, Costly Lawsuits Cities and Businesses Face for ADA Noncompliance, Landmark Lawsuit: Oregon Department of Transportation ADA Settlement, How to Prepare Your Business for a Power Outage.

Curb Ramp Design. The latest guidelines specify facilities at sites meeting the Access Board’s criteria for public rights-of-ways, specifically public streets and sidewalks used by people with vision impairments. If sidewalks are less than 60 inches (5 feet) wide, passing spaces must be constructed every 200 feet. For instance, in subway and rail stations with elevated platforms, the truncated domes must run the entire length of the platform. ACCESSIBILITY CHECKLIST … 12(a)]. It is also dangerous. 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. Often, in these circumstances, private Read more about the dangers of homemade ramps here. (On a curb ramp, the cross slope is the slope perpendicular to [across] the direction of pedestrian travel on the ramp run.) C.    Why are Curb Ramps at Pedestrian Crossings Required? In addition, restricting access in public areas under current federal laws could be construed a form of discrimination against such individuals.2. 7 Following are the key characteristics of an accessible curb ramp according to the ADA Standards: The ramp run has the least running slope possible. These requirements can be in addition to those contained within the ADA. In this instance, installing curb ramps at the pedestrian crossings on the south side of the townhall are not needed from a program access perspective to enable people with disabilities to access the town hall. Bids must be on a unit price basis. Only measure the width of the ramp section of the curb ramp (labeled “ramp” to the right). § 35.151(b). Example: Installing Curb Ramps for Program Accessibility. The minimum clear width of a curb ramp, turning space, or sidewalk, is 4 feet. DOT has deemed this departure from the ADA Standards to be permitted under Title II of the ADA.16 An example of a curb ramp that complies with the DOT’s design can be seen on the right. The only other exception is in regards to cross-sloped ramps, where the cross slope maximum is a ratio of 1:48. The ADA Coordinator should oversee the city’s compliance with ADA regulations and investigate complaints or grievances from the public. One way to make curb ramps compliant with Title II of the ADA is to build them in accordance with the ADA Standards.7 Following are the key characteristics of an accessible curb ramp according to the ADA Standards: Perpendicular Curb Ramps in the ADA Standards: Flared Sides or Returned Curbs?
