This is not the first time Philadelphia’s sidewalk quality has been the subject of legal action. In 1993, a federal court ordered the city to install appropriate curb ramps on every city street, but in 2014, according to the suit, the Streets Department told two of the advocacy groups participating in the suit, Philly ADAPT and Disabled in Action of Pennsylvania, that it would upgrade curb ramps to be ADA-compliant only upon request, rather than automatically doing the work during repaving.
