A "third space" that encourages socialization, its easy access reduces emissions as well as drunk driving.
My friend Eliot Allen first introduced me to the concept of neighborhood completeness: that the quality of a place is defined in part by how many different functions it has in close proximity to homes and to each other. Eliot was closely involved in the creation of the LEED for Neighborhood Development green rating system, and the concept made it into the system. LEED-ND gives credit toward certification for a development that contains, or locates near, certain categories of diverse uses: supermarket, pharmacy, restaurant, child care facility, library, and so on.
I was part of the LEED-ND team as well, and I note that we did not list “bar” or “pub” as a credit-worthy neighborhood asset. But Michael Hickey, a community development consultant, makes a good case for their inclusion as “third spaces,” or community hangouts.
