Sidewalks are stupidly narrow here. Two people walking side by side can make it hard for people going the other way to walk around them. There are poles and trash cans and store front tables that take up even more room. Walking is a pretty dreary experience as a result - you feel like a second-class citizen.
I would love it if the city just took even like.. one street going east-west, and one street going north-south, and convert them to walkable promenades for a sizable portion. I'm curious why this hasn't happened yet - is there significant local opposition? For storefronts or restaurants, the direct in-front parking would be lost yes, but there would definitely be more foot traffic, and there would still be parking on adjacent streets. I suppose the main loser would be homeowners that use street parking.
