Brandon Donnelly — Daily insights for city builders. Published since 2013 by Toronto-based real estate developer Brandon Donnelly. — Page 499

Today was the SvNSpeaks event that I blogged about last week . As a reminder, the conversation was about how best to remove overly prescriptive and rigid development policies in order to better achieve our climate change goals. John Lorinc and I ended up agreeing on a lot of points, so maybe that suggests there's a relatively clear path here. Now it's just a matter of taking action.

It was a recorded event on LinkedIn, so if you'd like to have a listen, you can do that over here .

The City of Toronto's Official Plan directs growth to areas of the city that it refers to as Centres, Avenues, Employment Areas, and the Downtown. In other words, these are the areas where most new development is intended to take place. So if you own land in one of these areas, it is probably worth more than if it were outside of them, all other things being equal.

Avenues are what you might expect. They are major streets that run throughout the city (pink ones in the above map). But not all major streets are "Avenues." There are lots of major streets that provide connectivity across the city but still feel like residential streets (tired ones I might add) and that have land use policies that only allow low-rise housing. I have always viewed this as a mismatch and I have long been critical of it on the blog.

But as part of the City's Expanding Housing Options in Neighourhoods (EHON) initiative, this exact problem is being looked at. And I think it is one of the most important land use studies currently underway in the city. Because if we are truly serious about housing affordability and our low-carbon goals, we are going to need to blanket our city with a lot more transit-supportive density. And our major streets are great place to start.

I just hope that everyone involved will be as bold and visionary as possible. If you have any thoughts, please leave them in the comment selection below. And for the latest on this study, click here . It is an agenda item at next month's Planning and Housing Committee meeting.

When I was in Phoenix this past spring I noticed a number of people carrying their big dogs around. At first I wasn't sure what was going on. I thought maybe the dogs were injured and couldn't walk. But then it dawned on me that maybe the ground was too hot for the dogs to walk on it. Phoenix is kind of hot sometimes and so this appears to be a thing.

In response to this kind of hot problem, the city has a pilot program underway where they're testing out something that they are calling "cool pavement", which is essentially a highly reflective coating that gets layered on top of your traditional asphalt streets. Here's a video showing some of it getting applied:

The idea here is, of course, to lower the surface temperature during the day and also reduce the overall urban heat island. And after the first year of the pilot program, the results have been encouraging. Cool pavement had an average surface temperature that was 10.5 to 12 degrees Fahrenheit lower than traditional asphalt during the middle of the day.

But there have been some tradeoffs. Because of its higher reflectivity, mean radiant temperatures increased by about 5.5 degrees Fahrenheit during the day, which means that these streets feel warmer to humans when they're around them. That's obviously not ideal, but it could be a necessary trade-off to reduce surface temperatures across the city.
