One of the small things that I liked about living in Philadelphia was the rational way in which street addresses tended to work.
Here’s an example.
Let’s say you wanted to go to Brooks Brothers in Center City and you discovered that the address was 1513 Walnut Street (which it is).
By looking at the first two numbers, you would immediately know that the store sits between 15th Street and 16th Street on Walnut.
If the address you were given was 1601 Walnut Street, you would know that your destination is now between 16th Street and 17th Street, but probably right at 16th.
You would also know that the numbered streets run north-south and the streets named after trees run east-west. (Of course, not all of the east-west streets are named after trees.)
No need to pull up the Google machine.
All of this stems from William Penn’s incredibly rational 17th century grid plan for the city – one of the first examples in North America.

I like this comparison of street grids that Daniel Nairn prepared back in 2010:

There’s huge variation here. On the one end you have cities like Carson City, Portland, and Providence, which have small blocks (180′ x 180′ and 200′ x 200′). And on the other end you have cities like Salt Lake City, which have massive blocks (660′ x 660′).
Yesterday morning I went for a swim at the new Regent Park Aquatic Centre. I used to swim regularly when I was in grad school in the US, but it fell off when I moved back to Toronto and there wasn’t a convenient place for me to walk to. Having to drive to a gym or to a pool can really cut hurt how often you’re able to go.
In any case, the pool was fantastic. On the west side of it are glass sliding doors that face the park. And since yesterday was such a beautiful day, they were all open while everyone was swimming lanes. The wooden ceiling also gives the space a nice, warm feel.
The biggest surprise for me though was the universal change rooms. I had never been in a co-ed change room before – or one that was completely open and visible to the pool (there are small private rooms so you can actually change). For families, it makes a lot of sense. Everyone can go in together and it’s easy to watch your kids in the pool from within the change room.
After my swim, I rode my bike around Regent Park and tweeted this out:

What’s happening in Regent Park is incredibly exciting. To me, it feels like a return to the fundamentals of city building. They’ve reconnected the old street grid – which had previously been removed to create the old “towers in a park” scheme – and they’re clearly working towards a proper urban neighborhood with retail at grade and buildings pushed right up against the street.
A big measure of success, though, will be how animated the streets become and how well the retail does. Because all of that isn’t quite there yet. But we’re on our way. And already I feel like we’re about to forget what the old Regent Park used to be like. Toronto may have lived with that neighborhood for over 60 years, but future generations will barely know it existed.

This variation creates very different experiences for both pedestrians and drivers. It is widely understood that small blocks are better for walking, which is perhaps why Salt Lake City is known as a driving city. (I just learned that they have “crosswalk flags” to help pedestrians safely cross the street. What does that tell you?)
In the case of New York – with its irregular rectangular blocks – it is arguably one of the reasons why the avenues (short side of the rectangle) have such a different feel than the streets (long side of the rectangle). Walking north-south is more enjoyable than walking east-west.
All of this is even more interesting in the context of the point I made in this post: once these urban grids get laid out, they’re pretty sticky. That has far reaching implications.
