Accessibility for persons with disabilities, New Urbanist planners and architects will tell you, is an important principle. Still, other New Urbanist principles can come into conflict with accessibility; or, at least, they often clash with interpretations of the Americans With Disabilities Act, or with accessibility as defined by disability-rights advocates. Take February’s “Lifelong Communities” charette in Atlanta, at which Congress for the New Urbanism co-founder Andres Duany and Eleanor Smith, of the organization Concrete Change, were able to agree on the removal of requirements for elevated entries from the Duany Plater-Zyberk SmartCode—prized by New Urbanists for the privacy they enable, but a barrier for wheelchairs—but had to agree to disagree on issues including the utility of walk-up apartments located above retail.
