Portland Taking Interesting Approach To Creating Walkable Sustainable Neightborhoods

Just read this great article over at grist.org, where the mayor of Portland OR talks about creating what he calls 20 minute neighborhoods throughout the Portland MSA. His definition of a 20 minute neighborhood is effectively a neighborhood where you can walk or bike to restaurants - they liken it to a "mixed use development."

It would seem Philadelphia is extremely well positioned to leverage this concept as it's a city of neighborhoods. It would be interesting to see this concept made part of the Greenworks Initiative or some other program(s).
