Note: This column was originally titled, "A Stupid Attack on Smart Growth," intended as a pun on 'smart' and 'stupid.' However, that sounds harsh so I retitled it. - T.L.
The National Association of Home Builders (NAHB) has a well-financed campaign to discourage communities from considering smart growth as a possible way to conserve energy and reduce pollution emissions. They contend that compact development has little effect on travel activity and so provides minimal benefits. The NAHB states that, “The existing body of research demonstrates no clear link between residential land use and GHG emissions.” But their research actually found the opposite: it indicates that smart growth policies can have significant impacts on travel activity and emissions.
Last week, I was busy trying to turn my paper on sprawl in Canada (available at http://works.bepress.com/lewyn/65/) into a speech. In my paper, I define sprawl in two ways: where we grow (measured by growth or decline of central cities, controlling for municipal annexations) and how we grow (measured by modal shares for cars and transit). As I was proofing, I asked myself: why these particular measurements? What presuppositions underlie defining sprawl based on, say, modal share as opposed to the growth of a urban area's land mass?
