Walkable real estate is in high demand in America’s large metros, and tomorrow’s most successful cities will be the ones that capture that market—but the walkable places they build may not look like today’s downtowns.

In Foot Traffic Ahead, our June report co-released by our LOCUS coalition and the Center for Real Estate and Urban Analysis at the George Washington University School of Business, we ranked America’s largest metropolitan areas based on their projected future growth in development of walkable places. That list of nascent future walkable real estate hot spots included surprise contenders like Atlanta, Denver, and Los Angeles—far from the usual suspects for such rankings. Meanwhile, some famously walkable cities like Portland, Pittsburg, and Baltimore were projected to fall behind.

The difference owes to walkable sub-urban places, an unconventional category that includes both historic town-center type suburbs and modern transit-oriented developments. In our highest-projected metro areas—from Washington, DC to Atlanta, GA—a large percent of new growth is expected to take the walkable sub-urban form.
