UBC 97 Zone 0 ????

[geng]

Our client specifies the use of UBC 97 , Zone 0 , Soil type SD. However table 16-I defines no Z-factor for Zone 0.

Can you please help me out ?

The z factor for Zone 0 is: Z=0

If Z=0 , does this mean earthquake need not to be considered , because if using Z=0 , the factors Ca and Cv for earthquake design are not listed ?

Zone 0's are "earthquake free zones". No earthquake is allowed per 20CFR19Q. j/k. Seriously. Yes, earthquake need not be considered in Zone 0.
