   Here's where Walk Appeal gets really interesting, and walkability theory turns into real-world survival… or thriving. This is a satellite photo of St. Charles, Missouri. They have an iconic American Main Street there, just off the river. I've selected a random store near the middle of Main Street; it's the black star in the green circle. Next, I looked at the conditions on the ground to see how far people might walk.

   At the Main Street setting, as you'll recall, people are likely to walk 3/4 mile. But On Main Street in St. Charles, they run out of the Main Street before they run out of their 3/4 mile, beginning at this store. If the subsequent street is a good urban neighborhood street, then they use up their remaining walking distance at a 1/4-mile rate.

   But have a look at what happens just North of the store: Just after turning left off Main Street onto the big street that runs West-Northwest, the streetscape drops quickly to the parking-backed standard, where people are lucky to walk 25 feet. And there, the walking stops… as any visitor to St. Charles can quickly see. The total area in this store's customer capture ends up being 87 acres. At an average density of 10 homes per acre (some Main Street apartments, most detached urban neighborhood homes) that's 870 households. By today's real estate rules of thumb we discussed earlier, that's not enough to support even a single corner store. Most stores on Main Street are surviving, if not thriving, calling that rule of thumb into question (as I did earlier.) But I agree that this store is probably just hanging on, and definitely not thriving. Walk down Main Street in St. Charles and you'll see what I mean.

   What happens if St. Charles were to do nothing more than repair the streetscapes in the problem areas to the levels of their healthier surrounding streetscapes? This would allow the store at the star to reach out much further for customers into the surrounding streets of St. Charles, as you can see above. Their customer capture would expand by more than double to 198 acres, or 1,980 households at the same 10 households per acre. By anyone's standards, this store's prognosis changes from questionable survival to thriving, based on walking traffic.

   It's important to note that businesses can thrive by attracting customers beyond the range of Walk Appeal. But then you need to provide parking for all those customers that make the difference between survival and failure. And once you get to the point that you need to park more cars than can be parked on Main Street and the alleys, then you're faced with the prospect of finding other ways to park them. And the parking lots that are most often used are precisely the things that kill walkability most quickly. So a town really does need to decide whether each part is a walkable business area or an automobile business area.

   Let's look at one more possibility: What if St. Charles was so happy with how Main Street was thriving as a result of healing the problem streetscapes that they decided to let everything in the area move up one standard? So that everything at the Main Street standard gets to move up to the London standard, and everything at the neighborhood street standard gets to move up to the Main Street standard? If they do this, the map changes to what you see above. The customer capture area has more than doubled… again… to 427 acres. But because the higher standards include more households per acre, the total number of households changes to something closer to 10,000. Now, the only thing standing between the business at the star and strong prosperity is the quality of their products and services.

   Many of the implications are obvious… and stunning. But you may see some implications that I don't yet see, so rather than me going on about what this means, let's discuss… what do you think?

   PS: Lloyd Alter, Kaid Benfield, and others have suggested dropping the Transect nomenclature I used in the first Walk Appeal posts because the millions of people who don't know the Transect won't know what we're talking about. I've done that in this post, as you can see.
