How many urban residents can safely walk to work, and to school, and to entertainment? It’s one thing for a neighbourhood to be walkable. But being able to walk between neighbourhoods is “Deep Walkability” and not that many cities offer it.
For older cities that have compact neighbourhoods, good walkability is common. This is where the walkscores in the 90-100 range are. But even in these places walking between neighbourhoods isn’t always that pleasant (although it may be doable). This is because even 100 or more years ago, and especially in the mid 20th century, cities tended to separate messy, polluting industrial areas from residential ones.
Today, industrial uses between residential areas tend to be more benign–self storage facilities, catering operations, etc. But they often don’t contribute to deep walkability because these places feel isolated and empty, even in the middle of the day (or they’re used by prostitutes and drug dealers).
By contrast, walking down a dense residential street or along one with mixed retail and residential is filled with people and interesting things to look at. It also feels safer than the industrial area described above. As Jane Jacobs correctly observed about great urban neighbourhoods, there are lots of “eyes on the street.”
Until walkable corridors are created between some neighbourhoods, many cities will struggle to offer deep walkability (and even cycle-ability). I see this change happening over the next few decades. Gradually, some industrial areas are becoming artist live-work spaces, or being filled with start-up companies whose employees will support any retail that can be carved out in the area.
Does your city offer deep walkability? if not, what are the obstacles? if so, have their been some changes recently as suggested here, changing over industrial space?
