The Alameda County bomb squad responded to the scene after the package was found in the parking garage underneath the Plank restaurant.
Businesses in the area and pedestrians were evacuated and train traffic on on the Embarcadero was halted.
Authorities have since determined the package was not explosive, and the area has been deemed safe and reopened.
