Despite not being the first example of infrastructural adaptive reuse, the High Line in New York has certainly kickstarted an urban trend. Cities all around the world now want their own “version of the High Line.”

Philly is working on a new “rail park.” I toured the space last summer and it’s very similar to the High Line in terms of existing infrastructure. Rome and Toronto are both working on “under” spaces, which are beneath an old viaduct and elevated expressway, respectively. And the list goes on.

But I think it’s worth remembering just how contentious the High Line was before it was built. For some people it was just an eyesore and a public safety hazard. Here’s a excerpt from a New York Times article dated 2002:

“This is a terrific win for us,” said Michael Lefkowitz, a lawyer for Edison Properties, one of 19 businesses that own land beneath the High Line.

Janel Patterson, a spokeswoman for the city’s Economic Development Corporation, said an agreement to share the $11 million cost of dismantling the High Line was being circulated among the property owners and the rail bed’s owner, CSX, of Richmond, Va. “It’s about eliminating a public safety hazard,” Ms. Patterson said, “but it’s also about enabling the city to move forward and better develop the area.”

It’s also worth mentioning that former Mayor Giuliani supposedly favored demolition of the High Line. Former Mayor Bloomberg, however, did not:

…Mr. Bloomberg said: "Today, on the West Side of Manhattan, we have an opportunity to create a great new public promenade on top of an out-of-use elevated rail viaduct called the High Line. This would provide much-needed green space for residents and visitors, and it would attract new businesses and residents, strengthening our economy. We know it can work … . I look forward to working with Friends of the High Line and other interested parties to develop a feasible reuse scenario.”

The challenge with these sorts of things – that is, new ideas – is that we live in a world of proof and precedents. We want to see that it has been successfully done before, because, otherwise, we might be wrong. So now that New York has shown what is possible, it has cleared the way for other cities.

Rethinking old infrastructure is a sound urban strategy. But we also shouldn’t forget that it’s less valuable to be right about something that every other city already believes to be true. The real value is created when you’re right about something that most other cities don’t yet believe.

In 1933, the United States Congress created the Home Owners’ Loan Corporation (HOLC). With foreclosures rising as a result of The Great Depression, the task of the agency was to provide new low-interest mortgages to both homeowners and private mortgage lenders. Between 1993 and 1936, the agency served about one million households.

By 1935, the parent company of the agency (the Federal Home Loan Bank Board) decided to initiate something called the “City Survey Program.” The idea was to look at local real estate trends – including the racial and ethnic composition of the country’s largest cities – in order to get a better understanding of how to manage all of these outstanding loans.

One outcome of this program was the creation of the HOLC’s infamous “residential security maps.” (Philadelphia’s is shown at the top of this post.)

These were maps that categorized city neighborhoods according to 4 grades. Grade A neighborhoods (green) were the best ones. They were ethnically homogenous and had room to be further developed. Grade B neighborhoods (blue) were the second-best ones. They were already completely developed, but were still considered desirable. Grade C neighborhoods (yellow) were starting to decline and showed an “infiltration of a lower grade population.” And finally, grade D neighborhoods were considered “hazardous” and colored in red. These neighborhoods had low homeownership rates, old crappy housing, and an “undesirable population”, which, at the time, largely referred to Jews and African Americans.

Some have argued that the HOLC and their “residential security maps” are what kicked off systematic mortgage discrimination in America’s inner city neighborhoods – later referred to as “redlining.” This was the practice of denying credit to people who lived in these undesirable neighborhoods (and even to real estate developers who wanted to build in these undesirable neighborhoods).

But University of Pennsylvania professor Amy Hillier has argued that these maps simply reflected the ethos of the time period. Using a sampling of HOLC mortgages, she found that 62% of them were issued to grade D (red) neighborhoods. The agency, itself, was not actually redlining in practice.

Furthermore, she also looked at private mortgages issued in Philadelphia between 1937 and 1950 and found that security grade rating actually had no impact on the total number of loans issued. She did, however, discover slightly higher interest rates for properties located near and in the bottom security grades.

All of this is to say that “redlining” is likely not the only culprit for inner city decay. There are other factors at play.

To that end, the National Bureau of Economic Research recently published a working paper, which I discovered through CityLab, called, “Racial Sorting and the Emergence of Segregation in American Cities.” The key finding here is as follows:

“Our preferred estimates suggest that white flight was responsible for 34 percent of the increase in segregation over the 1910s and 50 percent over the 1920s. Our analysis suggests that segregation would likely have arisen in American cities even without the presence of discriminatory institutions as a direct consequence of the widespread and decentralized relocation decisions of white urban residents.”

In other words, it wasn’t just mortgage discrimination; it was also just general discrimination. That actually makes a lot of sense, because, if you think about it, the former couldn’t have occurred without the latter being present.

Here’s how the research paper puts it (via CityLab):

“Policies that reduce barriers faced by blacks in the housing market may thus not prevent or reverse segregation as long as white households have the ability and desire to avoid black neighbors.”

(Note: Most of the information and data used in this post was sourced from the work and research of Amy Hillier.)

Thanks to this blog, it’s pretty easy for me to go back and look at what I was doing and thinking throughout the year. That’s one of the benefits of writing a daily blog/journal. And as is usually the case, 2015 was a year of ups and downs.

For my annual ski and snowboard trip with the guys, we went to Banff (Alberta) and Revelstoke (BC). But we got stuck with unseasonably warm weather in the west (the opposite of what’s happening this winter) and I got injured on day 3. That put me in the emergency room and knocked me out of snowboarding for the rest of the season – as well as from the gym for a number of months.

Shortly after that I also got struck with some family health issues. That was pretty scary for a good solid month, but in the end, everything seems to have worked out. What a relief.

Towards the end of March, I did a brand partnership between Architect This City and Porter Escapes, which brought me to Quebec City for a weekend. That was a lot of fun and gave me the opportunity to be a real flâneur in one of the most interesting cities in Canada.

In April, I left my real estate development job at TAS and shortly after I joined CAPREIT (TSE: CAR.UN) to help build out their (real estate) development platform. Previously their/our focus had just been on acquiring existing rental assets. But now it is time to build.

Later this month I also participated in the Toronto filming of a documentary called Waterfront Cities of the World. That was a lot of fun. But come to think of it, I don’t think I ever watched the final video.

In May, I started lobbying hard for the removal/replacement of the eastern portion of the Gardiner Expressway East here in Toronto. If you’ve been reading this blog since the summer, I am sure you remember this period. With the help of a colleague of mine, I even started a petition that ended up getting presented at City Council.

But in June, Toronto City Council voted to demolish and then rebuild the elevated expressway along our waterfront. I am still surprised by that. What a shame.

In July, we (CAPREIT) announced our first joint venture development project. A mixed-use project – 506 rental apartments on top of about 160,000 square feet of retail – in Toronto’s Liberty Village. 

In August, I went back to Philly to relive my Penn days. I do that every couple of years just to make sure that Bob and Barbara’s is still offering up “The Special.” The Special is a can of PBR and a shot of Jim Bean for $3. It’s famous in Philly, but it always sounds like a far better idea the night before, as opposed to the morning after.

In this same month I also hit the 2 year mark here on Architect This City. That’s 2 years of getting up every single day and staring at a blank blog post screen and thinking of something insightful to say. 

The following month on September 11 (I’ll never forget this date), I got laser eye surgery. More specifically, I got custom wavefront LASIK. And today it’s pretty hard to imagine that I used to have to reach for my coke bottle glasses as soon as I woke up every morning.

Later in September, I also gave a talk at my alma mater, the Rotman School of Management, to a delegation of about 70 urbanists from Portland. It was an honor to be invited alongside rockstars such as Richard Florida and Jennifer Keesmaat.

In October, I featured a guest post from the former mayor of Toronto, John Sewell. I don’t often do guest posts on my blog, but John had just published a new book and I thought it would be a good way to change things up here. John and I aren’t necessarily on the same page with many urban issues, but we did agree on the Gardiner East.

For the remainder of October, it was basically just the Jays.

In November, I spoke at a Product Hunt event focused on real estate + tech. It was incredibly encouraging to see so many entrepreneurs here in Toronto focused on the intersection of real estate and tech. There are lots of opportunities in this space and I am sure that there are many success stories in the making right now. Toronto is the perfect place for real estate + tech innovation.

And finally, in December, I crossed something off my bucket list and attended Art Basel Miami Beach. I have wanted to go for well over a decade; pretty much since I started studying art history in undergrad. I don’t know what took me so long.

Oh, I also announced that I was writing a book on becoming a real estate developer. 

What a year. I can’t wait for 2016. 

What do you have on your to-do list for next year?
