A former 107-acre public housing site in South Pittsburgh’s St. Clair neighborhood is being transformed into a massive urban farm. According to Next Pittsburgh, once construction of the Hilltop Urban Farm is complete, the site will be home to the largest urban farm in the U.S. The project will consist of 23 acres of farmland and about 70 hillside acres of walking trails, green spaces and conservation areas. The Urban Redevelopment Authority will set aside 14 acres for potential future housing. The farm will host a farmer’s market building, a three-acre Community Supported Agriculture (CSA) farm, a one-acre fruit orchard, a three-acre farmer incubation program, a one-acre youth farm with an environmental education building, a community garden, an on-site compost processing facility, as well as an events facility.
