Thirty-two submissions were selected as universal design exemplars. One of those was the Brookfield Zoo in Brookfield, Illinois. However, the zoo was selected as an exemplar in universal design, not as having followed accessibility laws or codes. Exhibits and displays appeal to a variety of people. These include large, high-contrast types, mounted high enough so they are easily readable by most people.
Walks are wide and accessible to all, including people using wheelchairs.
Large, diverse groups can view exhibits at the same time. This is helpful for people who are visual learners or non-English speakers, or who have limited vision, limited color acuity, or cognitive disabilities. Other stations provide audio output, and the tram is equipped with assistive listening devices. Sculptures are placed so they do not constitute protruding objects. The ADA's accessibility requirements apply to both new construction and existing facilities.
