When Stephanie Walsh and her husband were looking to buy a home in Atlanta, GA, they had a pretty unusual set of qualifications for their new home: They wanted to have access to local, organic produce (and not just from the grocery store); they wanted a neighborhood that was easily walkable; and they wanted to be true friends not just smile and nod acquaintances with their neighbors. On a whim, she searched the internet for ecofriendly neighborhoods near Atlanta and happened upon the website for Serenbe, a community of 270 green homes and 30 retailers planned around a 25-acre organic working farm and 15 miles of trails. I fell in love immediately, she says. Theyve now lived in Serenbe for over four years, and Walsh says they hardly ever leave. Serenbe is whats known as an agrihood, a community that is usually planned around a farm and offers access to unblemished landscapes, locally grown food, and homes built to environmentally friendly standards. The planning of agrihoods is done in a way that fosters community and interaction between the people who live there. In Arizonas Agritopia, fences arent any higher than 5 feet, making it very easy to have a conversation with the family next door when you see them in their backyard. Every house has a front porch, and the houses are closer to the street, says resident Katie Critchley. You can be sitting on your porch and be able to have a normal-decibel-level conversation with someone walking their dog. It forces you to say hello.
