seismic accelerations

Good morning,

 

Working on a project "generic" for entire State of California, and need to estimate the highest seismic load for a city in the state. 

So far, the highest accelerations I found were in the City of Rancho Cucamonga (Ss=2.670, S1=0.968, higher than even in Richmond or Berkeley).

 

Is anybody aware of even higher values anywhere in the state?

 

Thanks,
