Originally designed by SOM in 1963 as an administrative center and plaza over a parking garage, the plaza was renovated in the 1980s, at which time the lower terrace levels were largely removed and replaced with planted areas. Later additions included an access ramp that effectively cut-off portions of the plaza from use by pedestrians. When these earlier renovations began to deteriorate—including spalling concrete paving and leaking membrane above the parking garage—Hitchcock Design Group and the project team were hired to design and document the plaza renovation. This included coordinating the design of a new waterproofing membrane system with the addition of clay brick pavers, installation of a hydronic snow-melt system, new planting beds with irrigation, new pedestrian and effect lighting, and the integration of the access ramp into the larger circulation system. The plan also provides new benches, signage, raised planters, and bicycle parking. Future phases will include a zero-depth fountain, monument stairs, and site walls.
