A walkable street ensures that people can safely cross from a clothing store to a coffee shop and spend money at both. It means that people who live in the neighborhood can grab groceries and other necessities easily, so they’ll probably visit nearby establishments more often. Perhaps most importantly, a walkable street is one in which many businesses occupy the bulk of the land, meaning that dozens of destinations can be accessed in a matter of minutes on foot, and that every inch of land is put to economically productive use — not squandered in empty parking lots or unnecessary landscaping.
