Illinois
ADA Site Accessibility Compliance
Survey and design of accessible parking, ramps, curb ramps and routes to meet the 2010 ADA Standards.
What the work involves
Civil engineers evaluate and design the site portion of accessibility: accessible parking and van spaces, curb ramps, slopes along accessible routes, landings, and connections from parking and public sidewalks to entrances. The work often starts with a slope survey and barrier report and ends with redesign drawings. Accessibility lawsuits frequently target parking lots and routes, so owners commission audits proactively.
