Is $110k enough?

Hey all! I’m going to be taking a job in Sunnyvale sometime in June. I’ll be moving from the East Coast with my 2 kids and husband. When I tell people about us relocating, the reactions I get are instantly “wow the Cost of Living is high out there”. This has got me thinking, in the event that my husband doesn’t find a job right away, is $110k enough to keep us above water? We have about $2k in normal bills (phones, time shares, credit cards, car insurance etc). Just looking for some thoughts- should I be worried? Am I making a terrible choice for my family moving out there with that salary?
