Searching Google for Local Government Documents
You can search government documents from California specifically using Google. By including the "site" command in your search, you limit your search to a particular site or range of sites. For example:
site:.ca.gov (searches the California state government and many California county governments)
site:.ca.us (searches many California city websites)
There are exceptions to these rules for counties and cities. Your safest bet is to search site:.gov and include the name of the city in the search as well as your topic keywords.
