I have worked for public agencies since the early 90's and have see the evolution of the ADA act since that time. at 1st it was ramps, then ramps with certain grooves, then ramps with certain slope requirements and then the introduction of the raised dome tile 10-12 years ago. you see them now embedded into chair ramps, exits of your favorite store. they are everywhere, and mandatory even for the smallest of business.
so, while driving around at work today I saw what appeared to be construction activity at the only gun store in town. when I realized what was going on I circled back and captured these shots!!!
yep, ADA tiles to alert the blind they are entering traffic after leaving the gun store. so good! hopes this does not get PARF'd, but they are slim.
