Call KKMI in Pt Richmond (510 236 6633)and ask Ginger, the lady who runs the front desk, for a list of people they use. We saw a few surveyors that came through to do work
while we lived there for about 6 weeks. I noted a french lady ("fran-swah" -- I have no idea how to spell it*) who was VERY thorough and seemed well considered. Ginger can probably tell you how to contact her.
If you can actually talk directly to Mike Hadley, Project
Manager there, he can give you the name of the best in your area of interest. We've had great luck with all their referrals, and think you'll do well with them.
