Not to stray off topic too far, but to answer Vonny's question. In addition to the DC neighborhoods already mentioned (Dupont, Adams Morgan, & Penn Quarter), Logan Circle and the U Street corridor were also two of my favorites, both neighborhoods growing into their own over the past decade. Columbia Heights / Mt Pleasant (they have a "Mt Pleasant" as well
) has come a long way in the past few years. Capitol Hill does tend to be a bit quieter. It tends to be a bit more residential but even there the street life on the retail corridors is lively and diverse, with wide sidewalks of cafes and coffee shops.
DC is just a good example of a city that had the right "ingredients" but needed the finances and investment and will to bring it together, which fortunately they've been able to do over the past couple of decades. The reason the fabric was there, though, was in large part because of the design and zoning restrictions. Without them that city would have been lost in a sea of interstates and highways 30 years ago.
I don't expect Vancouver to be DC. I just cringe a bit when I see the arguments that seem to scream for dropping the provisions that have helped shape Vancouver in the past twenty-five years. The future growth needs to remain smart growth. And you don't get smart growth by just throwing the doors open to whatever comes down the pike. You might get a few creative flourishes, but you might well end up with a hodgepodge that does little or degrades the livability of the city. I think it would be wiser to "stretch the city out a bit further" than to have policies that encourage a fortress of super-highs in the downtown corridor. Vancouver simply doesn't have the avenue-style streets needed to support it. A typical street in Manhattan is about twice as wide as the typical street in downtown Vancouver, with wider sidewalks as well. And the density of towers (in the sense of towers in scale to their surroundings - not height) is, aside from a few sections, not much greater than downtown Vancouver has now.
I do think there is a place in Vancouver for taller towers, and a review of view cones is a good idea. But I think that any change should be considered carefully, very carefully . . . not subject to random whims or fads. Vancouver needs to consider the shape of the city 20, 40, even 50 years out in the future. And it should carefully ensure that the qualities that make the downtown great now remain in place for the most part.
