Hampton from the park to all the way to Gravois is a good case study for land use planning gone wrong.
I think you mean "lack" of planning. Hampton happened as an auto-oriented commercial strip, just as everyone started to drive their own SOV cars, and public transportation, especially street cars, was being put out of business in STL.
It's a bizarre area. Some places have opened outdoor patios (Joey B's, Twiggs, Pueblo Solis, St. Louis Pizza and Wings, a couple of Bosnian-owned cafes further south). Patrons of those establishments get to "enjoy" the noise and smells of zooming traffic a few feet away.
It's adjacent to some of the most prosperous city neighborhoods (the Hill, Dogtown, Lindenwood, Clifton Heights, Southampton, St. Louis Hills). And for whatever reason, the residents of those neighborhoods and their leaders (well, except for Ald. Ogilvie) won't begin to consider big ideas for slowing traffic/making the area more pedestrian friendly. Maybe part of the problem is the fact that the street passes through five wards on its way from Forest Park to Gravois?
The results? Many failed businesses. A dearth of greenery. Lots of car accidents. It's not an attractive landscape. My theory as to why this is?
The people in these neighborhoods are too comfortable. They are complacent. They fear change. The heavy Catholic presence is even more loathe to change. They don't much question the status quo (another Catholic thing?). However, rather than make changes, they like to complain, especially about things like crime, but don't do much to consider how they might work to improve the area. They equate "change" with decline.
The wave of Southside progressive reform hasn't reached this area. It's still very old school/traditional. It's not like South Grand. It's a DINO stronghold. It's a place where lots of politicians live and get votes, and a place where old traditions are strong. And those traditions are very autocentric/Catholic-school focused, preserving the status quo.
Wouldn't it be nice to see progressive conversations about the future of Hampton similar to those re. the future of Gravois? N. Florissant?
Think that'll ever happen? My Magic 8 ball says "No". Too much risk in rocking the status quo. Better to let the area tatter around the edges, being the change no one wants, until problems are much worse, than to acknowledge there is any cause for concern. Oh, and money. You'll always hear that first: there's no money. Well, what about forming one or more CIDs/SBDs?
