Some nice data layers, but unfortunately the roads are still TIGER:

The GIS Coordinator is linked off of this page. They say that the
Level I data is public domain -- if what you want is not linked
above, I would contact the GIS coordinator directly and ask.

Hello,
I know it's a long shot, but I'm wondering if anyone knows of any
free sources of detailed roads data for California that is better
than Tiger. Or, are there any WMS services out there that offer
better data? We are a non-profit organization who is publishing
an interactive map of public parks in the state. We've tried
overlaying our data on top of a google basemap using OpenLayers
but the result is confusing. Ideally, we would like to create our
own custom basemap. Tiger data will suffice, but it would be nice
to have better data. I don't suppose any of the large data
organizations such as tele atlas ever offer low-cost licenses to
non-profits?
Any suggestions would be appreciated.
Thanks,
Jennifer
Have you considered writing to Caltrans about data? Might be worth
a shot. The engineers and web people I've talked to there are all
about sharing, and it might be catching on with the management.
Cheers,
Sean
