The project would consist of a one- or two-story building of approximately 12,000 square feet with an 8,000 square foot footprint and 4,000 square foot mezzanine and outside seating area. With infrastructure, excavation, work areas, laydown areas, and spoils piles the disturbance area is estimated at approximately 20,000 square feet (8,000 building + 4,000 mezzanine and outside seating + 4,000 spoils + 4,000 road access and laydown areas). The rooftop may incorporate a seating area, photovoltaic panels, solar hot water heaters and/or a "greenroof". The construction method would consist of a combination of slab-on-grade and drilled piers and pre-cast exterior panels. Design criteria would incorporate sustainable principles and be constructed to Leadership in Energy and Environmental Design (LEED) Gold standards as a minimum.
