Haya El Nasser and Paul Overberg report on the 2011 U.S Census survey and find results showing a ten-year trend.
To be sure, no one is suggesting that walking, biking, and public transit will replace the private automobile in neighborhoods composed mostly of single family homes, even new ones. However, even Stephen Melman of the National Association of Home Builders did state about the findings: "It's very positive about public transportation if new construction is starting to be built closer to employment centers or transit."
The porches may say more about homebuyers desire to interact (to a certain level) with their neighbors than mobility.
"The front porch acts as a social mechanism," says Christopher Leinberger, president of Smart Growth America's LOCUS, a coalition of developers and investors who promote walking over driving. "You sit on the porch and talk to people walking by without having to invite them in. It's outdoor space without taking up too much space."
Also reporting on the findings, Streetsblog Capitol Hill's Tanya Snyder writes, "(D)evelopers are (belatedly) building what the market wants: denser housing in walkable urban centers near transit. Copious parking and driveway curb cuts simply don't mesh with that model."
