Showing an alternative, Pennsylvania has several towns and cities with a split-rate tax, which means that there's a higher tax on the assessed land value than on the assessed value of the property. Taking this to an extreme, you can tax only the land value, not the property, providing a very strong incentive to make the best use of desirable land. A split rate tax just lets you turn the dial between typical property taxes and a land tax.
Many arguments in favor of the land value tax are based in concepts of economic rent and fairness. While I'm sympathetic to these arguments, I think the best argument is that it seems to work, both in theory and practice. Places that implement a split rate or land value tax tend to have fewer empty lots, parking lots, single-family homes in the middle of downtown, etc.
And not just that, but typical property taxes provide a disincentive to even improve your own property, since you'll pay more tax. They encourage blight.
It's not just California, it's everywhere. Tax policy isn't the only thing stopping us from avoiding sprawl by "thickening up" valuable areas of towns and cities, but it's a big one. Parking minimums are another, and of course zoning is yet another. All of them are important in terms of making our cities walkable, amenable to public transit, and sustainable environmentally.
*edit -- I should clarify that Prop-13 makes this effect worse in California than many places, though.
