The Plaza Garage is a five
level below ground pre-cast concrete structure of fire
resistive construction with a landscaped park on the roof of
the facility at ground level. The structure covers one
square city block.
The garage has an interior fire alarm system
consisting of manual pull stations, and heat detectors
at the elevator lobbies which transmit a signal to the
Pine Street Police Station. A dry pipe sprinkler system
has been installed throughout the facility, with water
flow devices and valve supervisory switches
interconnected to the building fire alarm system.
Portable fire extinguishers in "break glass" cabinets
are provided in various locations.
Fire department suppression equipment is limited to
dry standpipes in the main entrance/exit located
on the Redwood Street side (south) and three stairways
located at the northwest, northeast, and south sides.
The exterior doors to these stairways are located
on the common level and entrance may only be gained
by keys kept in the garage attendants booth. The
fire department Siamese connections for the stand
pipes are located at the main entrance/exit and at
the southeast corner of the common area (Redwood
and Paca). Knox FDC caps have been installed
on the fire department connections to prevent vandalism.
A Knox Box has been installed next
to the fire alarm annunciator with keys for elevators, mechanical areas,
electric areas and fire alarm panels to be used by the
fire department as needed.
A key for the Knox FDC caps is
also located in the Knox Box.
This building is classified as a Storage occupancy.
