Northern California includes 48 counties, here are some of them. That's a lot of counties, I need a map. What a big state this is. I think there are 57 total.
- Contra Costa

What happens if I drop a First Draft GIS map in here?
City of Pleasanton has a tiny bit here: http://www.cityofpleasantonca.gov/gov/depts/gis.asp
http://www.co.contra-costa.ca.us/1818/Maps-GIS *requires registration (when GIS data is outlawed only outlaws will have GIS data!)
When you want data from the county site and it says "it's not here", then go here instead: ftp://atlas.ca.gov/pub/coco-county/
MarinMap is the county consortium site. Lots of data here.
They have TIFF and MrSID format 6" aerial photos for the entire county. You can download a vector grid to determine which tiles you need.
"The County does not offer public access to interactive GIS information, but you may contact the County's Information Services Department at (707) 463-7200 and ask for 'GIS' for more information regarding GIS data layers."
Monterey county's GIS office is in Salinas The county uploads all its data to arcgis.com. http://montereycountyopendata.montereyco.opendata.arcgis.com/

County of Santa Clara GIS data You must file a request to get centerline and parcel data. Other than the request form they have links to other sites. You can view their data in a map viewer but no direct download facility exists.
Santa Clara Valley Water District GIS data Their data is in arcgis.com but they have links to other sites here.
Search in arcgis.com under "Santa Cruz County Open Data".
To build a map quickly your best bet is to load layers directly from ArcGIS Online, that's how they are making available most of their vector data.

Hillshade in QGIS
Create a gdal service description file, e.g. by running this in a terminal:
gdal_translate "http://mangrove.cnr.berkeley.edu/arcgis/rest/services/SONOMA_HYDROFLATTENED_BARE_EARTH_HILLSHADE/ImageServer?f=json&pretty=true" s.xml -of WMS
You can now load this file into QGIS, e.g. by drag-and-drop.
