CULTURAL RESOURCES SURVEY REPORT 4400 Black Ave 26 THE WALLED GARDEN As mentioned above, this feature fills the angle between the front two blocks of the building. The surface is paved, and the area is filled with a mix of steel and concrete tables and benches. The area is protected on two sides by four-foot-high wooden walls made of brown diagonal boards and darker trim that are the same as are found elsewhere in the building. A trellis-like structure of wooden beams covers most of the walled garden. These beams are supported by square wooden posts with wooden trim that look the same as the posts that support the roof over the adjacent entrance area. The visual connection between these posts is continued by a row of four similar pilasters in the front-most part of the building (to the left of the entrance path). INTERIOR The interior is divided into two large rooms and many small rooms. Both of the large rooms are in the building’s rear block; they are labeled “UNIT I CACD” and “UNIT II CACD” in the framed floor plan within the building. UNIT I CACD is now devoted mainly to storage, while UNIT II CACD is furnished with tables and chairs and is essentially a large meeting space. Between these two large rooms are several smaller rooms. One of these is filled with steel racks that once held a great deal of electronic circuitry and wiring that supported the call center’s use. Much of this circuitry has been removed since it is no longer needed, but some remains. The interior finish is mostly utilitarian. Wall surfaces are variously plaster or are covered with lavender- colored fabric; the latter (found in the UNIT I CACD room) is likely non-original. Ceilings are drop acoustical ceilings. Floors are variously carpeted, linoleum tile, or (in UNIT I CACD) concrete. Paired wooden doors can be found in one room, namely the former lounge. Lighting is of two types. The primary lighting is fluorescent panels set flush within the ceiling. Other fluorescent lights, found only in the UNIT I CACD and UNIT II CACD rooms, are suspended from the ceiling. These were most likely placed in 1998, according to a building permit. Two hallways can be found in the building. One runs south from the main entrance to the rear block. It meets another hallway that runs east-west along the north side of the building’s rear block. This hallway is about 87 feet in length and is lined on both sides by 202 narrow steel lockers for the call center’s employees.
