The Case for Open Space explores the benefits of private sector involvement in creating, maintaining, operating, and programming parks and open space—ranging from enhanced returns on investment for developers that include open space in their projects to improved community health outcomes. This publication by the Urban Land Institute's (ULI) Building Healthy Places Initiative and ULI's Sustainable Development Council (SDC) incorporates research conducted by ULI staff and SDC members, as well as takeaways from stakeholder interviews—including with ULI members who have developed or supported parks and open space through their project investments.
