When you rezone a property to build something new, pretty much every city will ask you to provide reports and studies that assess the potential impacts of that something new.
They’ll ask you to look at the impact on traffic, the impact on storm water, the impact on shadows in the area, and the list goes. This, of course, is fair and reasonable. It makes sense to measure the impact of the proposed changes to see if it will work in the given context.
But those are not the only impacts to consider. I think that many of us underestimate the flip side, which is the impact of doing nothing, or in this case, building nothing. Here’s a recent quote from an excellent interview with urban economist Edward Glaeser:
Personally, I believe there are always huge costs to saying “no” to people who want to create space for new families that want to live in the city; who want to make the city more affordable. There are always costs – I believe that very, very strongly – but, sure, there are also benefits to saying “no” at certain times.
Glaeser is, of course, not saying that we should allow unfettered development. He is saying that there are costs (or impacts) to building and costs to not building. The challenge is that we assume, often incorrectly, that saying “no” simply means the status quo will prevail. And we do not consider the impacts.
So what does that mean? Here’s an example.
The Neptis Foundation, which is a nonpartisan and charitable urban research group, just published an interesting report called, Growing Pains: Understanding the new reality of population and dwelling patterns in the Toronto and Vancouver regions.
What the report did was compare growth and settlement patterns in both the Greater Toronto (and Hamilton) Area and Metro Vancouver between 2001 and 2011. And what they found was two different stories.
Of the one million people that moved to the Toronto region between this period, roughly 80% of them settled in new greenfield housing subdivisions at the urban edge. And only 18% of people moved to areas that were well serviced by public transit.
By contrast, only 31% of Metro Vancouver’s population growth went to greenfield areas and 69% went to urban intensification areas. Nearly half of these new residents ended up settling next to high frequency transit.
From an environmental standpoint, Vancouver’s settlement pattern is obviously preferable. But it takes hard work to achieve that. The barriers to infill development are more formidable than the barriers to greenfield development. This is despite the fact that there are well documented social, economic, and environmental costs associated with urban sprawl.
My point with this example is that growth and demand will find somewhere to settle. Some locations make more sense than others, but sometimes there’s no choice when we have decided to say “no.” So what we ought to be doing is measuring both the impact of building, as well as the impact of not building.
This morning the Globe and Mail published an article by Toronto’s chief planner, Jennifer Keesmaat, called Greenbelts make cities more livable, affordable and transit-friendly.
The headline immediately caught my attention because conventional economic wisdom would suggest that supply constraints – whether natural or artificially created – generally have a negative effect on housing affordability.
To be clear though, I support Ontario’s greenbelt. I think an urban growth boundary is the right thing to have if we want to build sustainable, walkable, and transit-oriented communities. But I’m also not blind to some of the potential (negative) externalities.
However, Keesmaat’s article got me wondering just how prevalent those externalities might be and to what extent our greenbelt is actually impacting housing affordability in Toronto. In her article she cites a recent report by the Pembina Institute that very clearly argues the following:
“There is no shortage of land throughout the GTA [Greater Toronto Area] to build single-family homes for decades to come, but this land is predominantly located far from the City of Toronto and other established centres of employment in the GTA.”
More specifically, the report found that of all the land available for development in the region (within our growth boundary), 81% of it is projected to still be unused by 2031. This got me thinking: it’s not that there isn’t land still available in the region; it’s that there isn’t land in the areas where demand is the greatest.
Put differently, young families aren’t clamoring for single family homes in High Park and Leslieville because the greenbelt has restricted their ability to find new housing. They’re doing so because they want to live in neighborhoods like High Park and Leslieville.
If you dive into the data, the report shows that in 2004 the average price of a detached home in Toronto was about $117,000 more than the rest of the Greater Toronto Area. As of 2013, that spread had grown to about $200,000. And indeed the data shows that it’s the core of the city where home prices seem to be appreciating the fastest.
So when it comes to housing affordability and supply, the greenbelt may actually be a red herring. Releasing it would not increase the supply of housing in areas where demand is already high, which is probably why this same report also found that – with or without an urban growth boundary – most Canadian cities are seeing similar increases in home prices.
So what should we be doing?
I think we should do two things: (1) focus on accommodating more growth in the areas that people already want to live in, and (2) figure out ways to transform the less desirable areas into more desirable ones. This second one will be the hardest, because it’s likely going to mean changing car dependent areas into transit-oriented ones, which is no easy task.
The good news though is that we are already doing these things. There’s more that I would like to see happen, but we’re headed in the right direction.
If your city has a greenbelt or you have experience with greenfield development in the Toronto region, I’d love to hear your thoughts in the comments. This is an area of development that I’ve never really been involved with.
