I've lived in the area in the past. You'll be pretty disappointed in NoCal beaches if you don't own a thick wetsuit. Stinson is probably your best bet. It's about an hour away. Maybe 40 minutes to Dillon Beach. Maybe there's something passable in Bodega Bay; that would be a few minutes closer. Honestly, every time I made the drive it was so cold and foggy we had fish and chips and couldn't even tell we were at the beach (that's how thick north coast fog is) and then drove home. It's a beautiful area if you like wine. In the past I would have recommended living in Healdsburg, but it's so touristy now and the area seems to catch on fire every couple of years.
RE wages: no way they're paying more than Kaiser. I don't have the numbers in front of me, but Kaiser is just over $180 a year right now (for new hires). Kaiser does allow you to waive all your benefits (including PTO), at which point your gross would be a little over $225. That would be on a 40 hour week, California and the pharmacist unions have very friendly OT laws, so you could get that up to $270 without too much trouble. Anyway, I'd guess they're talking the entire benefit package (including the employer's, SS payments, workman's comp, and unemployment payments) and then adding on all the holidays you'll have to work. And then adding on another 50 grand to get you to apply for the job so they'll have your info to spam you with other jobs.
Update: Found the posting. Shows it pays a $30,000 bonus + relocation. I'm a little surprised they're having that much trouble filling it. I'm a little tempted...
