The high-water mark for American parking policy came in the early 1970s, when cities including New York, Boston, and Portland set limits on off-street parking in their downtowns. They were compelled to do so by lawsuits brought under the Clean Air Act, which used the lever of parking policy to curb traffic and reduce pollution from auto emissions. This level of innovation went unmatched over the ensuing three-and-a-half decades. Only now are American cities implementing effective new parking strategies that cut down on traffic.
