Actually a pretty old project, but take a look at the Park la Brea development in LA. It's a gated community in the middle of the town taking up two city blocks. They are extending the subway there as we speak.

There's also the village green, where the interior of the development is completely pedestrian only. That place isn't far from the expo light rail and the upcoming lax light rail.

LA has a lot of small bungalow courts that face inward to a courtyard rather than the street, but they aren't nearly to the scale as the above developments.
