I have a 120kW project in Northern California.  I need to confirm the seismic zone for the building location in order to determine if we will need seismic anchors for our ballasted racking solution.  Is there a particular resource or website that I can visit to calculate the seismic zone?

Are there some ballast manufacturers that are less likely to require seismic anchors because of their design/approach?
