Excerpt:

A Southern California developer last week shared its sweeping new plans for a giant housing community on the former Alameda Naval Air Station. Officials for SunCal Companies spoke at a town hall meeting about the importance of building dense urban development, limiting suburban sprawl, and combating global warming. But they did not disclose that their proposed 4,200 to 6,000 units of housing will either cost local taxpayers tens of millions of dollars or snarl traffic throughout Alameda and downtown Oakland.
