The Lake Vista neighborhood [0] in New Orleans nailed this as well, but sort of flipped the alley concept. Still has street access and parking for every home, but the "front" of most houses faces an alley-width, pedestrian walkway. It was always one of my favorite areas to hang out as a kid, never really understood why until now.
