The American Disabilities Act has specific requirements for wheelchair ramps. This paper will explore those requirements and determine if the ramps on Sequoyah’s campus meet those requirements. ADA requires a ratio of 1:12 slope ratio, which is equivalent to 4.78 degrees or one foot; meaning there needs to be one foot of wheelchair ramp for each inch of rise. For example, a 40-inch rise requires 40 foot of ramp. The requirement for the landing, or the area at the top and bottom of the ramp has to be at least 5’ X 5’ and be a flat area. ADA standards require wheelchair ramps to have a minimum of 36 inches of clear space across the ramp. That means that the width of the ramp has to be at least 36 inches. The ADA also requires that for every 30 feet of wheel chair ramp there has to be a landing. The handrails of the ramp have to be between 34” and 38” in height. In trigonometry, the class went out to measure 27 ramps around Sequoyah’s campus to determine if they meet the American Disabilities Act requirements.

Do Ramps On Sequoyah Campus Meet The American Disabilities Act Requirements
The Board of American Disabilities Act established an advisory committee to conduct a complete review of ADAAG (American Disabilities Act Accessibility Guidelines) and to recommend changes. The ADAAG Review Advisory Committee consisted of 22 members representing the design and construction industry, the building code community, State and local governments entities, and people with disabilities. The committee was charged with reviewing ADAAG in its entirety and making recommendations for updating ADAAG so that it remains consistent with technological developments and changes in model codes and national standards and continues to meet the needs of people with disabilities. The committee developed a comprehensive set of recommendations that address changes to ADAAG and technical requirements as well as its format and numbering system. Cited as an outstanding example of reinventing government, the Committee and the Board received the Vice Presidential Hammer Award in July 1996.
There are many accommodations to help people with disabilities on the Sequoyah High School Campus. Some of these being power buttons to open doors, handicap stalls in bathroom, lever door handles instead of knobs, and wheelchair ramps. The American Disabilities Act has specific requirements for wheelchair ramps. The trigonometry class at Sequoyah went around campus and took measurements of 27 wheelchair ramps to determine if they meet the American Disabilities Act requirements. The width, height, length (which would be the hypotenuse), rail height, and landing were all measured. To find the height of the ramp a laser, plum, and yard stick was used. First the height of the laser was measured. Then the plum was held at the end of the ramp to make sure the yard stick was level. The laser was then placed at the top of the ramp and hit the yard stick making...
