Great example of SF attempting a Better Streets policy. Some of you bring up great points, however other crucial points get overlooked. The alternative to place greenery within the sidewalk is great, but the planning involve will still leave car-parkers in a muddle. In order to make the alternative work, you're looking at expanding the pedestrian zone, which most likely include nixing some parking spots. SF is a pedestrian-heavy metropolitan. And in this era of a floundering economy, it's faster & cheaper to make use of what's already there, versus building & expanding.
