The Johns Hopkins University Applied Physics Laboratory underwent an initiative to redevelop its central open space and associated dining terrace. Ayers Saint Gross’ landscape architects designed a unified master plan linking a large green open space with the more intimate human scale spaces. Stormwater management control was incorporated as an attractive amenity and solves functional purposes. A dining terrace expansion allows for shaded seating and provides a larger space for events. The adjacent Central Green area has a loop path for exercise, plantings for shade and a series of small “Innovation Spaces” for impromptu meetings.
