Generic Retaining Wall Schedule SF Bay Area

[Asher47]

I want to create a generic retaining wall schedule that I can use for smaller projects in the SF bay area up to 8'-0" or so. Worst case assume Clay, sandy clay, silt and sandy silt, SDC E, Site class D:

Bearing 1500 PSF
Passive 100 PCF
Active ????
Seismic ????

How do Geotechs determine a 10H or 8H wall for seismic, what would be most conservative value? What would be the most conservative value for an active pressure?

Thank you!
