We Had To Destroy the City In Order To Save It

Interesting article from the Urbanophile about density, zoning, and housing affordability.


Ed Glaeser’s plan for more skyscrapers in California?
As housing prices and rents soar out of control in tightly regulated cities like San Francisco and New York, many people have called for a significant loosening of zoning rules to permit greater densification. Many policies contribute to unaffordable housing, including rent control, historic districts, eminent domain abuse, and building codes, but zoning puts an absolute cap on dwelling units per acre thus is generally part of any solution to the supply problem. What’s more, as recent commentators have started to notice, even many of America’s most dense cities are predominantly zoned for single family homes, calling into question the need to dedicate so much space to a single housing typology.
For example, a web site called Better Institutions posted this map of Seattle, in which all of the yellow districts are zoned exclusively for single family homes:

The poster lets his feelings be known by using scare quotes to denote single family “character” and blaming the zoning for Seattle’s high rents.
And Daniel Hertz posted a similar map of Chicago in which the red is single family homes only and yellow is industrial space unavailable for any residential use:

Some go beyond affordability, saying that we also need to significantly increase densities in central cities in order to reduce greenhouse gas emissions. Harvard professor Ed Glaeserwrote an article advocating this subtitled, “To save the planet, build more skyscrapers—especially in California.” He says, “A better path would be to ease restrictions in the urban cores of San Francisco, San Jose, Los Angeles, and San Diego

More building there would reduce average commute lengths and improve per-capita emissions” and “Similarly, limiting the height or growth of New York City skyscrapers incurs environmental costs. Building more apartments in Gotham will not only make the city more affordable; it will also reduce global warming.” He claims that, “The best thing that we can do for the planet is build more skyscrapers.”
