Good point. Also, don't forget shade trees(and I don't mean palms) planted at regular intervals along the whole length. That softens the urban boundary at the sidewalk and makes it inviting. Furthermore, Central is far too wide to really encourage walking or strolling. I think you would have to remove a lane and make the sidewalks far wider, then creating a line of good palo verdo or mesquite, then it might not look so auto-centric. Maybe then Jane Suburb might be tempted to take a walk down it instead of Joe Shopping Cart.
