I just looked up the population density of several mid-sized Silicon Valley / Peninsula cities, from 6,000 to 8,500. These places are urban and haven't uniformly realized it yet.

And then some, like Palo Alto, have a lot of unpopulated or barely-populated area: openstreetmap.org/relation/1… Probably the parts between Foothill Expressway and 101 (or, more so, El Camino Real and 101) are close to that density.
