Tales from two cities:

San Francisco: From Ilan Greenberg in The New Republic – San Francisco’s Gentrification Problem isn’t Gentrification. Greenberg compares the public debate (often writen, and discussed previously here) in San Francisco compared to more the more familiar narrative in other cities.

Here, the debate is dominated by fierce new champions of the anti-gentrification cause who aren’t concerned so much about the truly poor being forced from—or tempted out of—their neighborhoods. In their view, the victims of gentrification are also affluent, just less so than the people moving in. And the consequences are supposedly catastrophic not only to these relatively well-off people who are living amidst people even more well-off, but a mortal threat to nothing less than the rebel soul of San Francisco.

While the conversation may not fall into the same narrative as other cities, that doesn’t make it more useful. Greenberg notes that the San Francisco conversation can “suck the air out of a reality-based conversation” about affordability.

Greenberg spoke with Peter Cohen, a San Francisco housing advocate:

Sitting in the worn lobby of a hotel patrolled by security guards near Twitter’s new corporate headquarters, and armed with documents showing statistics on skyrocketing rents and rising tenant evictions, Cohen came to talk about disenfranchised people struggling to keep financially afloat and about the legal intricacies of deed-restricted affordable housing. He said he expects to have an uphill climb to reach new residents obsessed with buzzy restaurants and city officials in thrall to new tech business interests, but now also struggles to be heard over the din of middle-class residents moaning about the “gentrification” of their neighborhoods—residents who themselves may have been gentrifiers, or more likely followed in gentrifiers’ footsteps.

Greenberg writes of this narrative as if it were inevitable: “The compact city has a long history of clubby NIMBYism and knee-jerk preservationist politics that torpedoes even the most sensible development projects.” In addition to the outright opposition, fees and a long approvals process increases barriers to new housing supply in the city.

Some opposition to new development is that it makes the city dull. This isn’t the first time such arugments have come up. Inga Saffron, also writing in The New Republic made the same case that gentrifcation brings monotony. Writing specifically of San Francisco, Charles Hubert decries the “homogenization” of the city.

Part of the challenge is that rebuffing that monotony probably requires more development to meet the demand, not less. It’s a somewhat counter-intuitive proposition. Another challenge is the notion that cities do not (or should not) change, when history says otherwise.

Brooklyn: San Francisco’s experience is not to say that fears of monotonous development aren’t somewhat warranted. Unleashing the market alone won’t solve all urban ills. The Wall Street Journal looks at the results of one of New York City’s rezonings, ten years later, with some detrimental effects on 4th Avenue in Brooklyn:

But the Planning Department lacked such foresight in 2003 when it rezoned the noisy avenue to take advantage of the demand for apartments spilling over Park Slope to the east and Boerum Hill and Gowanus to the west. Focused primarily on residential development, it didn’t require developers to incorporate ground-level commercial businesses into their plans, and allowed them to cut sidewalks along Fourth Avenue for entrances to ground-level garages.

Developers got the message. With the re-zoning coinciding with the real-estate boom, they put up more than a dozen apartment towers, many of them cheap looking and with no retail at the street level, effectively killing off the avenue’s vibrancy for blocks at a time.

The city finally got wise and passed another zoning change last year, correcting some of these mistakes.

The shortcomings on 4th Avenue show the tension between market urbanism and proscriptive/prescriptive urbanism (and both words probably apply) but it also shows the power of incentives and how development tends to follow the path of least resistance. But it’s not like this outcome is solely a product of the market.

Some of the architects responsible for middle-brow architecture along Fourth Avenue are surprisingly candid about the other cause: They pass the buck to the developers who hired them and the pressure they faced to cut costs at the expense of aesthetics.

“I try to do my best for my clients and try to get them as big a building as possible,” says Henry Radusky, a partner with Bricolage Architecture and Designs LLC, which has built nine buildings along Fourth Avenue in the last decade.

One of Mr. Radusky’s buildings was 586 President St., one of three buildings on the same two-block stretch of the avenue that contribute to its canyon of mediocrity look. Another is the Novo Park Slope, at Fourth Avenue and 5th Street, a pallid, prison-like structure with parking and a medical facility at ground level that towers menacingly over its next-door neighbors.

That parking, of course, is the product of prescriptive regulation. Market pressures might impact some design choices, but the relative impact of those decisions (compared against higher quality materials or prioritizing retail uses on the ground floor) likely pales in comparison to the cost and spatial needs of parking.

Back in San Francisco, Peter Cohen is looking for ways to mesh the market and prescriptive elements together:

Even housing advocates like Cohen concede a hard ideological approach loses hearts and minds. “I also understand that we have a changed disposition toward cities. How can you find a sweet spot between these two forces—how do you bring in this creative class, but also make sure that people who toiled in the weeds are not simply squeezed out? How can you sort it without just saying that the market will take care of everyone, when obviously it won’t?”
