I was really curious about the discussion between mrnyc and 10023.
I think this is the neighborhood in question when referencing the Loring Park Greenway in Minneapolis. I spent some time on Google streetview going through the neighborhood. First and foremost, it's very silly to relate this to NYC's Highline. It's not even close! I noticed the lack uses as it's mainly residential (the highlight has a mix of retail and entrances to commercial and residential buildings along with the beautiful views).
The Loring Park area circulated in red gave me very strong towers in the park vibes. In other words, it has the density with none of the benefits. I feel most people would use a car to get around unless they're just walking or jogging for recreation and not going to any destination in particular. I also wonder how women would perceive the safety of the area at night. This is normally not an issue for men, but these towers in the park type developments reduce visibility and women feel less safe at night walking around alone. Having retail and "eyes on the street" help lessen that impact.
Not the worst development I've seen. That remains the public housing developments of the 1960s, which just created concentrations of poverty with no economic opportunity followed by single-family sprawl over farmland. But I would activity be protesting if this was development being proposed in my city. I would instead favor something connected to the street grid with mixed uses and incomes. These large master plan developments built by a single developer almost always get it wrong.
Anyway, never been to Minneapolis. Just curious about the debate and wanted to see the neighborhood in Google streetview to get a better understand. I might have it all wrong.
