Americans With Disabilities Act

Every American deserves the dignity to live independently in a safe environment. Today, there are more than 40 million people with disabilities in the United States, and as the population ages, that number is projected to grow dramatically. There are currently more that 10 million blind or visually impaired people in the U.S., with someone new becoming blind or visually impaired every seven minutes.

One of the most sweeping federal laws for civil rights ever passed is the Americans with Disabilities Act of 1990. The ADA ensures that public domains in the United Stats are safe and accessible to everyone, regardless of health or handicap.

To provide a safer environment for visually impaired citizens on public street and sidewalks, the Americans with Disabilities Act Accessibility Guidelines (ADAAG) mandate the use of detectable warnings on curbs ramps, hazardous vehicular areas and transit platforms. By rule, detectable warnings are to consist of raised truncated domes with a diameter of 0.9", a height of normal 0.2" and center to center spacing of normal 2.35"
