I have been a bit remiss in checking for California projects on FamilySearch as we went for quite a long time without any. But there is a project available on the indexing site now. It is a collection of Alameda County Obituaries dated 1985-2006. This is considered an intermediate project. Read through the .pdf on Indexing Obituaries and Death Notices Projects before you get started. It will answer a lot of questions you might otherwise have.
If you belong to the California Genealogical Society there is also an ongoing project involving indexing San Francisco Coroner’s Records. Contact CGS for information on how to sign up for that project.
