In an excellent blog post, Reuben Duarte explained that many big-city zoning disputes involve a conflict of visions: a “preservation camp” favors preserving neighborhood character at all costs, while an “affordability camp” favors construction of new housing in order to make the city more affordable.
Duarte write that the preservation camp’s interests “hover around preventing evictions of tenants in long-held residences, but also includes the topics of traffic (“this neighborhood can’t support more development, because, traffic!”), parking (replace “traffic” with “parking”), and neighborhood character (“building is too tall or too dense!” “Views!”).”
It seems to me that to the extent government uses preservation as a reason to exclude new housing, arguments based on “neighborhood character” fail on their own terms: either because limiting housing supply itself changes neighborhood character, or because it forces less exclusionary places to change their character.
Zoning restrictions designed to limit traffic create the second problem. For example, suppose a city freezes a neighborhood’s housing supply in order to limit traffic and parking. Other things being equal, fewer households mean fewer cars. So at first glance, this policy has no losers. But if a city or region is adding households, those new households have to go somewhere. And if they don’t go to your neighborhood, they go to another neighborhood, adding cars (and thus traffic/parking problems) to that neighborhood. Continue reading
