Gradual Redevelopment Trumps Mega-Projects

The Atlantic Cities recently reported on a new study that shows having housing of different ages promotes social ties. The article proclaims that “Jane Jacobs was right” notes that “the results should get planners to stop and wonder whether newer is always better.” It continues,

Empirical results show significant links between housing age diversity (historical development pace) and four measures of neighbourly social relations, even when controlling for other neighbourhood housing features, social composition and individual sociodemographics. It may be that gradual redevelopment preserves community ties, which may take decades to form and which new residents may ‘inherit’ from previous neighbours.

There are a few lessons for the Wasatch Front that we can extrapolate from this study:

Neighborhoods with a diverse mix of building ages foster the most social ties.

1. We shouldn’t be building sprawl, which by definition lacks buildings of diverse ages. This finding seems to support my view that gussied up suburbs like Daybreak aren’t going to be really great for a 100 years or so — after they experience redevelopment. And in any case, it’s tragic that we’re building sprawling, car centric places that aren’t going to be worth anything until long after we’re all dead.

2. Flipping the article’s thesis on it’s head, we should be adding new structures to historic neighborhoods. Just as contemporary neighborhoods like Daybreak don’t work because they’re entirely new, old neighborhoods need diversity as well. This supports the idea that we need infill in historic neighborhoods. I don’t know why this isn’t happening in Provo’s residential neighborhoods; the benefits far outweigh the challenges.

Historic buildings are great, but it's also important to continually add new structures to the mix as well. This fun new building is located in Salt Lake.

3. “Social ties” should be a goal when deciding how to plan our cities. Provo is more or less doing this right now with the Center Street redesign, but few other projects seem to begin with the primary goal of fostering more, better social interaction. However, if we do take that as our objective many disagreements — and pointless NIMBY complaints — will be easier to solve.

4. And, finally, Jane Jacobs’ style observational analysis is a valuable way to understand the built environment. That may seem obvious, but our most expensive projects along the Wasatch Front — the I15 Core project, the proposed super street, the interchange catastrophe — are operating under an entirely different set of assumptions.
