Sounds like your colleague sleeps quite restfully at night due to his conservative approach...not that there is anything wrong with that choice.

The reason I was asking is because the other day an engineering collegue told me he designs to the middle third for retaining walls for non essential facilities.  I wonder if  that was required from an old code requirement or maybe some older soils reports required it?
 
Thanks for your feedback.

This is an arguable issue, but I accept the design if outside middle third if soil pressure OK and stability >1,5.

California Building Code section 1806A.1 requires the resultant must be in the middle half using 1605A.3 load combinations. I don't see this requirement in chapter 1806. For non essential facilities are there any requirements for the retaining wall resultant, or do we just need a 1.5 safety factor?
