This Planned Manufacturing District is defined by zoning to foster manufacturing through prohibiting residential development and other specific uses; this lack of flexibility can leave areas with vacant and underutilized land without integration with the surrounding neighborhoods. The site, a prime example, consists largely of vacant lots with a train line cutting directly through it. By building a platform on top of the rail lines, this approach kept the programmatic functions of a light-manufacturing district at the base while creating a space for other types of development above. The roofs of the base buildings join with the rail platform to create a landscaped area that serves as a 28-acre public park for the surrounding neighborhoods.
