Hi,

I am using lateral bearing pressure = 100psf/ft as minimum without soil report. But it's very small to design embedment of deep footing.
Can I apply CBC sec. 1086.3.3 to increase this value.
Thanks in advance.

If the pressure is caused by earthquake overturning, you are permitted to decrease the effects on the soil by 25% per ASCE 7 section 12.13.4. Does this help?

yes right, but it's wind load. Sec. 1086.3.3 is still applicable?
