Annapolis Landscape Architects joined the OLBN Architects design team in developing the Green Plaza Feasibility Study for the Hubert H. Humphrey Building was to mitigate urban stormwater runoff. The historic minimalist form of architecture and site are from the 1970s and are key elements to preserve during the process. Open space is mostly on-structure, requiring a green roof to absorb runoff. This was configured in panels to complement the site layout and striking plaza features, including a large “ziggurat” in the plaza paving and sculpture.
