Vacant lots, so often seen as neighborhood blight, have the potential to be a key element of community revitalization.Sandra Albro offers practical insights through her experience leading the five‑year Vacant to Vibrant project, which piloted the creation of green infrastructure networks in Gary, Indiana; Cleveland, Ohio; and Buffalo, New York. Vacant to Vibrant provides a point of comparison among the three cities as they adapt old systems to new, green technology. Albro offers insights from every step of the Vacant to Vibrant project, including planning, design, community engagement, implementation, and maintenance successes and challenges of creating a green infrastructure network from vacant lots in neighborhoods. Landscape architects and other professionals whose work involves urban greening will learn new approaches for creating infrastructure networks and facilitating more equitable access to green space.
