Maximum Ss and S1 in Southern California

[mcr07]

I'm working on a project that will require the knowledge of the maximum Ss and S1 for site class D in Southern California.
Can anyone point me in the right direction in order to find this information?
I understand we can use the tools at USGS to find site specific values, but I'm trying to find the maximum Ss and S1 in So-Cal.
Appreciate your help in advance,

Forgot to mention also, this is for an Occupancy Category I, II or III and under the ASCE7-05 Hazard maps.
Thanks
