By contrast, for pre-ADA highways, streets, roads, and sidewalks that have not been altered, state and local governments may choose to construct curb ramps at every point where a pedestrian walkway intersects a curb. their own behalf) have not provided the curb ramps at pedestrian Bids must be on a unit price basis. Wilmington, MA 01887, Tel: (800) 372-0519  The burden of proving technical infeasibility lies with the state or local government that constructed it. This Chapter discusses the ADA requirements for curb ramps at pedestrian crossings that are currently enforced by the Division under PCA. What are some key characteristics of accessible curb ramps? These ramps must have a slope of less than 1:12, must be at least 36 inches wide and must contain a detectable warning device with a raised dome surface and contrasting color. For more information about ADA curb requirements and assistance in selecting the appropriate tactile warning systems, please feel free to contact ADA Solutions today at (800) 372-0519! A parallel curb ramp consists of two ramps joined in the middle by a landing that is level with the roadway. Without ADA curb ramps, curb edges and a lack of accessibility would create hazards for those people with disabilities. 4. Combined curb ramps are a combination of the perpendicular and parallel curb ramp designs. 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. The warnings, which are intended to be felt with pedestrians’ feet, alert blind individuals and those with low vision that they are about to enter a street or other area where cars pass. instructions will also include photographs and illustrations showing how and 28 CFR § 35.107(B). Public transportation stops serving the town hall are in a residential neighborhood on East Street, two blocks east of the town hall. However, they are not necessarily required to do so. Here are some steps you can take: ADA Tool Kit for State and Local Governments, ADA Standards for Accessible Design (2010 Standards). What does “altered” mean? The ramp surface extends a minimum of 12 inches (305 mm) to the side of the handrail. E.    What are the General Requirements for Curb Ramps in the ADA Standards for Accessible Design? 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. after they are built by private developers and deeded over to the public But they are just one part. 12 ADA Standards § 4.1.6(1)(j). Crossings do not have to be marked, and there are no standards for how they should be marked. 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. The minimum clear width of a curb ramp, turning space, or sidewalk, is 4 feet. The Advisory Committee’s report is available on the Access Board’s website at www.access-board.gov/prowac/commrept/index.htm. These include bus, rail, and other facilities operated by federal agencies. Some facilities may benefit from other measures such as speed bumps, reduced traffic speeds, marked crossings, and other options. Now that you know some of the basic ADA requirements for providing curb Where and when must state and local governments provide accessible curb ramps? located in Appendix 2, and will provide an explanation of how to obtain the The FHWA website includes the following materials, which should be of particular interest to those entities receiving federal funds from FHWA: The process of adopting revised federal accessibility standards for public rights-of-way may be lengthy. Just knowing the ADA requirements is not enough to guarantee that your homemade ramp will be safe. Ensuring Compliance Now and In the Future. The Curb Ramps survey form and instructions will 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. survey form for use in conducting your surveys. However, in lieu of installing curb ramps and ramps, a facility may provide accessibility using elevators or platform/chair lifts.1 Furthermore, any accessibility routes which have a slope steeper than 5% have to be treated under the ADA ramp guidelines. The general ADA curb cut dimensions per the latest requirements under section §405 of the ADA curb ramp requirements for 2020 include: The available space of a curb ramp must be 36 inches wide, not including handrails, which must be installed on both sides if the ramp has a rise of greater than 6 inches. The requirements for curb ramps that have been altered post-ADA are the same, except for in the following cases. 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. to survey curb ramps for compliance with the ADA Standards and a Curb Ramps The landing clear length shall be 36 inches minimum. Some public entities have extensive responsibility for the highways, streets, roads, pedestrian crossings, and walkways in their area, but most public entities have at least limited responsibility for them. 2010 ADA STANDARDS FOR ACCESSIBLE DESIGN OREGON STATE BUILDING CODE JANUARY 2019 Northwest ADA Center University of Washington 6912 220th St S.W., Suite 105 Mountlake Terrace, WA 98043 Toll Free: (800) 949-4232 TTY/TDD/TT: (800) 949-4232 Videophone: (425) 233-8913 Relay: 7-1-1 Email Address: nwadactr@uw.edu Web Address: www.nwadacenter.org . They must be at least 48 inches long with 24-inch-long segments on either side beyond the flares. They must be integrated into the walking surface, and there are specific measurements for the size and spacing of the domes.13. The best way to determine if a curb ramp is accessible is to survey it to Under Project Civic Access (PCA), the Civil Rights Division works with local governments nationwide to help them achieve compliance with Title II of the ADA and Section 504 of the Rehabilitation Act of 1973 (Section 504). The federal government has begun a rulemaking process to revise the accessibility requirements for public rights-of-way. The slope is directly related to the rise (height) and length of the ramp. From the middle of one dome to the middle of another, there must be a distance of 1.6 to 2.4 inches.1. 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. 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. This is a choice that people with disabilities should not be required to make. The most common type of curb ramp is the perpendicular curb ramp, which intersects the curb at a 90-degree angle. Curb ramps must be placed to enable a person with a mobility disability to travel from a sidewalk on one side of the street, over or through any curbs or traffic islands, to the sidewalk on the other side of the street. Otherwise, the surfaces will be uneven due to the resulting slope and curvature. Side flares are included to reduce the risk of tripping. [§ 4.7.7], Transitions from the ramp to the walkway, gutter, and street must be flush (level) and free of abrupt level changes. ACCESSIBILITY CHECKLIST … 9 28 C.F.R. However, if a ramp run is excessively long, it can be difficult to navigate for those using a wheelchair or walker—a chair or platform lift might be used to mitigate this issue. 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. 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. Current enforceable standard is 2010 ADA Standards FHWA Memo 1/23/06 PROWAG –“recommended best practices, and can be considered the state of the practice that could be followed for areas not fully addressed by the present ADA standards” 3 Rulemaking Update The Access Board’s regulatory plan anticipated completion of a final rule for public rights-of-way and shared use paths. Curb Ramp Design. As long as a curb ramp or ramp doesn’t exceed 30 inches in height, there are no restrictions on length. Remediation of Pedestrian Signals To assist you, the next installment of this Tool Kit will include instructions on how These requirements can be in addition to those contained within the ADA. curb ramps which previously may not have existed. The town is evaluating where it needs to install curb ramps to comply with Title II requirements. Handrail extensions must be at least 12 inches long. Consistent with this Agreement, ODOT is tracking jurisdictional transfers that occurred in 2019 to ensure that necessary curb ramp remediation takes place. We offer a variety of solutions, from cast-in-place replaceable to radius systems in a variety of colors and cast iron, as well as photoluminescent systems. These include increased risks of falling out of a wheelchair or scooter or tripping while using a walker when going over an elevated curb. Updated: December 2019 2019 CALIFORNIA BUILDING CODE - SECTION 11B-405 GENERAL REQUIREMENTS FOR RAMP (This form may be used as a guide for checking Accessibility according with the 2019 California Building Code and shall not be considered a complete list of requirements) Ramps: Ramps on accessible routes shall comply with CBC 11B-405. Figure 4-2 - Limits of Protruding Objects (Guide to the ADA Standards) Exterior Ramps 1. If sidewalks are less than 60 inches (5 feet) wide, passing spaces must be constructed every 200 feet. Diagonal curb ramps can be used in place of two separate ramps for each crosswalk. [§ 4.7.2], The gutter must have a slope of no more than 5 percent (1:20) toward the ramp. 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. ADA Curb Ramp Survey Instructions Version 2.0 Updated 3/21/2019 Introduction The Central Region ADA Curb Ramp Survey Instructions and Inspection Forms were developed by the DOT&PF Central Region ADA Working Group. Each 48 inch (1220 mm) minimum by 36 inch (915 mm) minimum area shall be oriented so that the 48 inch (1220 mm) minimum length is in the direction of the running slope of the curb ramp it serves.

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 … The Idaho Americans with Disabilities Act (ADA) Curb Ramp Program is a state-administered program that provides funding for projects to address curb ramps on the state highway system. Example: Installing Curb Ramps for Program Accessibility. Generally, you must provide curb ramps wherever a sidewalk or other pedestrian walkway crosses a curb. crossings, transportation stops, and other locations that the ADA requires This eliminates an ADA curb cut and can be used to reduce the speed of traffic. Applicants can qualify for . Intercity and commuter rail stations fall under this designation as well. If “x” is 48 inches or more, then the flared sides may slope up to 10 percent (1:10) but not more. The requirements in the ADA Standards for curb ramps newly constructed post-ADA (construction commenced after January 26, 1992) can be found in § 4.7. Only measure the width of the ramp section of the curb ramp (labeled “ramp” to the right). § 35.151(a). The ADA curb ramp slope standards require the slope to be no more than a maximum of a 1:12 ratio or 8.33%. The details are reported in accordance with Section 8 of the Agreement on pages 15-16 of ODOT’s Annual Report. Below is a simple guideline for the California ADA ramp requirements that discusses ADA Regulations as well as California Building Code. [§ 4.1.6(3)(a)(ii)], The cross slope of the ramp run itself may not exceed 2 percent (1:50). Note: Data updates for this report reflect data collected through September 2019. In such circumstances, state and local governments must install curb ramps that provide accessibility to the maximum extent feasible.12 Before reaching a conclusion about technical infeasibility, state and local governments need to consider the extent to which physical or site constraints can be addressed by alternative curb ramp designs. If the island is too narrow for this, a level cut-through is permitted. Nor can they project into parking spaces or restrict access to aisles. [§ 4.7.3], The ramp run must have detectable warnings – i.e., dome-shaped bumps – that extend the full width and depth of the ramp. Side flares are not required on curb ramps but are essential when there’s not enough space for a top landing. developers (who are not bound by Title II’s requirements when acting on Transitions from ramps to walks, gutters, or streets shall be flush and free of abrupt changes. [§ 4.7.5; Fig. 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. Fax: (978) 262-9125, Monday – Friday: 8 AM – 5 PM “Questions and Answers About ADA/Section 504" (, a memorandum describing FHWA’s oversight role on federal accessibility requirements (, FHWA’s notice adopting the Access Board’s draft accessibility guidelines for the public right-of-way as currently recommended best practices (, FHWA’s memorandum on detectable warnings (, The ramp run has the least running slope possible. However, when the use of tactile warning curb ramps is required by federal, state, or local laws, they must comply with specific guidelines in regard to spacing, size, and contrast with the regular pavement surface. For ADA compliance, the minimum sidewalk width is 36 inches (3 feet), though sidewalks can be wider. Departures from particular requirements of either standard by the use of other methods are permitted when it is clearly evident that equivalent access is provided.6. On the bottom… The ADA curb ramp design standards for tactile warnings apply to areas that are designated for public transportation. “Pre-ADA” streets, sidewalks, roads, and highways are those that were built before January 26, 1992, and have not since been altered. In addition, restricting access in public areas under current federal laws could be construed a form of discrimination against such individuals.2. For instance, in subway and rail stations with elevated platforms, the truncated domes must run the entire length of the platform. A facility must install curb ramps or ramps in public areas along accessible routes with a change in height greater than ½ inch. To help you have a better understanding of the ADA ramp specifications and requirements, we will look at some of the more commonly asked questions by business owners, building managers, and construction companies. Furthermore, side flares used with certain curb ramp designs can only have a maximum of a 1:10 ratio.1. Complete all work within fifty (50) Contract working days. The 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. The purpose of these documents is to establish a clear and consistent process for measuring curb ramps for ADA compliance within Central Region. Design ramp runs to a maximum running slope of 1:13.33 (7.5%). Landings must be placed between each individual ramp. Section 5. Also, curb ramps and flared sides cannot project into parking spaces, parking access aisles, or vehicular traffic lanes. An alteration is a change that affects usability. What steps can you take to ensure that your entity is in compliance with the ADA requirements for accessible curb ramps at pedestrian crossings? Some intersections have curb ramps; most do not. Slopes of curb ramps shall comply with 4.8.2. Indentations, flared sides, or other features incorporated into the ramp’s design must not reduce the width below the minimum requirements. § 35.151(b). All curb ramps and ramps must be installed during initial construction or alterations and be permanent fixtures. What are curb ramps and what function do they serve? However, they may be needed from a program access perspective for other reasons, such as providing access to other town facilities served by the parking garage or to the town’s business district. University of Washington Accessibility Guidelines December 2019 Version 1.0 . A 3-ft pinch point is not acceptable. ADA Section 405 Ramps and 406 Curb Ramps We all know that one of the ways that people in wheelchairs maneuver between changes in level greater than 1/2″ is by using a ramp. The slope shall be measured as shown in. Most commercial construction projects must meet the parking standards outlined by the Americans with Disabilities Act (ADA). For instance, California laws have adopted the use of yellow as the only allowed color, with a few exceptions. 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. SIDEWALK WIDTH Sidewalk width requirements are especially important for wheelchair-bound individuals. D -2019 7 Office of Engineering Date: May 31, 2019 ENGINEERING DIRECTIVE Engineering Administrator Accessibility Guidelines in the Public Right-of-Way The U.S. Access Board is responsible for developing and updating the ADA Accessibility Guidelines (ADAAG). When pre-ADA streets or sidewalks are altered, there may be space limitations that restrict how much they can be altered to install accessible curb ramps. Parallel curb ramps run parallel to the curb and usually take up the whole width of the sidewalk. The Americans with Disabilities Act (ADA) includes requirements to make public areas accessible to wheelchairs, walkers, and motorized scooters through the use of ramps.1 These include ADA curb ramp requirements based on specific guidelines, depending on the type of ramp in use, its location, and other such factors. There is confusion between requirements for ramps vs. curb ramps. For specific requirements, you need to review your local requirements in regard to the width, height, appropriate markings, and so on. It is often difficult or impossible for a person using a wheelchair, scooter, walker, or other mobility device to cross a street if the sidewalk on either side of the street ends without a curb ramp. 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. Width: 48 inches clear space between handrails. Please note: This guideline is only intended to highlight our interpretation of some of the ADA Wheelchair Ramp Specifications or ADA Ramp Slope guidelines and is not intended to replace or supersede ADA guidelines, specifications or requirements. information needed to answer each question on the survey form. Overall, the ADA requires that a truncated dome has specific dimensions: Detectable warnings must feature a minimum space of .65 inches between the edge of one dome to the edge of another. 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. In case of an overlap, it’s highly recommended for the door to swing open in the direction opposite the landing. [§ 4.8.2]. Revised ADA Standards for Accessible Design (2010 Standards) were issued on September 15, 2010 and went into effect on March 15, 2012. In these cases, the curb ramps installed must meet the accessibility requirements of the ADA to the maximum extent feasible.10 Scoping requirements in the ADA Standards establish limitations for the running slope of the ramp run of curb ramps installed during alterations to pre-ADA streets and walkways.11. The landing clear width shall be at least as wide as the curb ramp, excluding flared sides, leading to the landing. Under Tennessee Code Annotated 54-5-202, the curb ramps are the responsibility of the local governments; however, TDOT is committed to full accessibility for everyone. Section 4.1 - Exterior Accessible Routes Page | 4 . They can be cut through or built up to the curb. In the meantime, many state and local governments will construct and alter highways, streets, roads, sidewalks, and pedestrian crossings. 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. 14 ADA Standards § 4.7.7. Under these requirements, the town may choose to install curb ramps at all pedestrian crossings on the sidewalks surrounding the town hall, but it is not necessarily required to do so. Extensions must be in the same direction as the run. For curb ramps constructed before January 26, 1992 (pre-ADA), including those that have since been altered, the running slope must generally be 8.33 percent (1:12) or less. When highways, streets, and roads are built or altered post-ADA, they must have curb ramps at certain locations. You can also download the pdf version of the California Ramp Requirements. Not all hazardous vehicle areas need tactile warning surfaces either. One way to make curb ramps compliant with Title II of the ADA is to build them in accordance with the ADA Standards. [§ 4.7.5] The slope requirements for the flared sides depend on the width of the sidewalk at the top of the ramp, “x” in the illustration to the right. Exception: In assembly areas, aisle ramps … Furthermore, the placement of the warning surfaces can and does vary, based on the location where it installed. If curb ramp flares are used, they cannot be steeper than 1:10. Transitions between the ramp and the sidewalk, gutter and street are located at the top and bottom of the ramp run. 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. A minimum of 36 inches (915 mm) is … Version 1.3 – September 11, 2019. [§ 4.8.2], For curb ramps constructed after January 26, 1992 (post-ADA), the slope must be 8.33 percent (1:12) or less. The only exception is where work area equipment that’s essential to the work being performed is used.1. A ramp can also overlap with a door opening clearance if the door does not open into the landing area. The ADA curb ramp slope standards require the slope to be no more than a maximum of a 1:12 ratio or 8.33%. 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. When an accessible route crosses a curb, it requires a “curb ramp”. compliance with these requirements. 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. 8 28 C.F.R. 4.7.3 Width 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. Please keep in mind that it is your responsibility to fully review the latest state, local, and federal requirements, as there are regular updates made to the ADA. 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. On November 23, 2005, the Access Board published revised draft accessibility guidelines for public rights-of-way, which are available on its website at www.access-board.gov/prowac/index.htm. (On a curb ramp, the cross slope is the slope perpendicular to [across] the direction of pedestrian travel on the ramp run.) In developing these draft guidelines, the Access Board obtained recommendations from an Advisory Committee composed of representatives from disability organizations, public works departments, transportation and traffic engineering groups, the design and civil engineering professions, government agencies, and standards-setting bodies. G. What are Detectable Warnings, Why are They Required, and Where Must They be Provided?
