The reporter found on site that several lighting strips in the underground garage are sensor-activated, staying at low wattage when no one or vehicle passes, and automatically switching to high wattage lighting mode when someone or a vehicle passes. "Previously it was said the underground parking lot would have epoxy flooring, but the current condition is cement flooring, and the lighting is insufficient. Parking spaces further inside and in corners have no lighting.
