I spent a good chunk of this morning talking and thinking about underground building details that most people (unless you're in the industry) would never think to consider. This is not a criticism on most people. I mean, I don't know how iPhones are made. I just use and enjoy them. But when it comes to buildings, I'm paid to ask questions and understand how things work.
There's a lot of risk in the ground.
You have to think about things like bearing capacity, environmental contamination (usually), hydrostatic pressure and, generally, how you're going to manage water, particularly if you have a high groundwater table. Usually this last one is about making sure you're keeping the water out. A pretty important detail both below and above grade.
So when I came home tonight and saw the below tweet, I felt obligated to write about it.
If you read the reply from NYC's Metropolitan Transportation Authority, you'll see that this is them testing something they call a "flex gate." It is a flood barrier that allows them to seal off subway entrances in the case of a storm surge and they run these tests (shown above) for 4 hours at a time to make sure

I’ve written quite a bit about the advantages of a “rail + property” model when it comes to building public transit. It’s a model that works quite successfully in other parts of the world, such as in Hong Kong.
However, in North America the notion of land value recapture or of transit authorities acting as real estate developers is still very much in its infancy. We’re myopically focused on rail.
Which is why I said about 3 months ago that if the stations along the new Eglinton Crosstown LRT line in midtown Toronto became single storey and single purpose buildings, that we will have missed an enormous city building opportunity.
Since that post I had a number of conversations with the folks over at Metrolinx and I was delighted to learn that there were in fact plans to build additional density on top of the stations. And as of today they’ve gone completely public with that intention.
Metrolinx, with the help of Avison Young, has just issued a request for proposal (RFP) for 4 sites along Eglinton Avenue in the city. Two of them are at Keele Street, one of them is at Weston Road, and the last one is at Bathurst Street. The 4 sites could generate between $14M - $22M.
The objective is to find suitable developer partners to help them build on top of their planned LRT stations. And it’s a step in exactly the right direction for Metrolinx and this city.
Today’s Architect This City post is being brought to you live from the mid-base lodge at Revelstoke Mountain Resort on Mount Mackenzie in British Columbia.
It’s currently foggy, rainy, and about 2 degrees celsius — which I’m told is fairly anomalous for this area. It’s unfortunate for my friends on the slopes, but it makes me feel somewhat better about hanging out all day to rest my back and shoulder.
The town of Revelstoke was founded in the 1880s when the Canadian Pacific Railway connected the area. And traditionally its economy has been closely connected to that rail. However, with amenities like the resort I’m currently sitting in, its economy now increasingly includes tourism.
One of the most interesting reminders for me on this trip through the Canadian Rockies is how instrumental rail was in unifying and then building this country. But in actuality, it wasn’t just rail. It was rail plus property.
Within the Canadian Pacific Railway was a division called Canadian Pacific Hotels, which built and operated both urban and rural hotels such as the Banff Springs Hotel and the Chateau Lake Louise (both of which I visited for the first time on this trip). And today, these railway hotels are absolutely some of Canada’s most inspiring landmarks.
The model at the time was simple.
Sir William Cornelius Van Horne — who was president of CPR in 1888 — believed: “If we can’t export the scenery, we’ll import the tourists.” He knew that it was all about moving as many people as possible. And to do that he needed to create accommodations and destinations all along the rail. In other words, rail alone wasn’t going to cut it. It had to be rail plus property.
This of course is a model that still persists today. Many public transit authorities, such as the MTR in Hong Kong, have been hugely successful by adopting a rail plus property model.
However as the case study of the Canadian Pacific Railway demonstrates this is not a novel approach. It’s actually a tried a true model. Rail, and infrastructure in general, goes really nicely with property development.
So why don’t all transit authorities adopt a rail plus property approach?
