Fire Station #31 was originally constructed in 1960. This station was scheduled for replacement as part of the City of San Diego's efforts to upgrade their fire protection services. The facility was enlarged to house the paramedic team and reserve apparatus along with state of the art equipment, for a total of 9,000 square feet.

The design facilitates emergency response functions of the paramedics and fire department.

Access requirements from the Americans with Disabilities Act are addressed in the new construction. The fire station is designed with environmentally friendly materials that contain recycled content and may be recycled more easily at the end of their useful life.

The massing, architectural character, finishes and landscaping of this steel-framed, stuccoed and tile-roofed facility reflect the residential neighborhood it serves. Energy conserving measures have been designed into the building envelope: daylighting illuminates the residential and equipment bay areas, and roof and walls are acoustically and thermally insulated. Energy conserving mechanical and electrical systems are also incorporated.
