Much of the saffron crocus sold commercially is undersized and won't flower 
until it's built up strength. Feed them well, but judiciously, this spring and 
maybe they'll flower this coming fall. If you get no flowers this year, be 
patient and give them more time.

As for winter chilling, we get adequate chilling here in Victoria BC for 
saffron crocus to flower. The Bay area may be too warm in winter, but if you 
plant your saffron on the north side of the house, close enough to the house to 
be in shade all winter, that may help.

Many crocuses seem to prefer a rather lean, sandy, sharply drained soil. If 
your native soil doesn't meet those requirements, this summer try replanting 
your saffron with a bed of clean sand under them, back filling the whole with 
more sand.
