Conventional planning wisdom tells us that smaller city blocks are generally preferable to larger city blocks. They make for more interesting walks (which can change our perception of distance) and they improve overall connectivity. This is why you'll often hear planners advocate for things like "mid-block connections." It is a way of creating the feeling of smaller blocks.

Salt Lake City, as we have talked about, is the opposite of this. Its blocks measure 660 feet x 660 feet (call it 200m x 200m for those of us more accustomed to using the international standard for measuring things). This means that if you were to walk only 2 blocks (inclusive of 2 streets), your walk would be close to 500m, which is a commonly used walking/transit radius.

Things get a bit tricker when you're not walking in a straight line. For example, if you found yourself wanting to cross a street somewhere in the middle of a block -- and you wanted to obey all traffic safety rules and not jaywalk -- you would need to walk over 200m just to get to the opposite side. So basically a whole other block.

There are also instances where even this street grid gets interrupted. This past weekend, I spent an evening walking to and from dinner on Main Street. And at one point, I got caught trying to cross the convention center (which occupies 3 blocks). I guess I could have tried to cut through, but I walked around, which added 2 additional blocks (~600m in total).

Thankfully, SLC also has many instances of new mid-block streets/connections, road diets, internal laneways, and enhanced center medians, among many other things. I mean, here are some plans to turn Main Street into a pedestrian promenade. All of these interventions are an effort to soften the city's underlying block structure, which we know tends to be indelible in cities.
