In 2007, then-Attorney General Jerry Brown established a new paradigm for planning in California. With his settlement in a lawsuit against San Bernardino County, he clearly signaled that cities, counties, and county subregions would have to account for, and attempt to mitigate, greenhouse gas emissions in their general plans under the California Environmental Quality Act and AB 32. In fact, Brown went so far as to vow to sue any city that failed to account for its greenhouse gas emissions.  

To some, infill development still occupies a quaint niche in the world of city-building. But over the past few years, greenfield development on the urban fringes has gone fallow and a host of economic, social, and regulatory forces have made infill more viable. Attempting to lead that charge is the newly formed California Infill Builders Association, a professional group made up of established and aspiring infill developers who seek mutual support in their effort to bring new development to urban areas.

The California Supreme Court will review a case in which Alameda County and a housing developer argue that a California Environmental Quality Act lawsuit filed by project opponents should have been dismissed because the opponents did not raise their objection during the administrative process.

Jamboree Road might not become the next Park Avenue, but a new vision plan recently completed by the City of Irvine signals a major shift away from the suburban lifestyle of Orange County. One of the early cities to pioneer the strict segregation of office-park style commercial development from master-planned residential areas, Irvine will be allowing thousands of new residential units into its business core in the coming decades. 

 The Vision California modeling exercise, however meticulous in its calculation methods, still relies on a slate of assumptions that call for some vigilant critiques. Calthorpe & Associates, which devised Vision California based on previous work, have stated elsewhere that the key to the global warming crisis lies in curbing "sprawl," that pejorative term for low-density suburban development. To the extent that a large lot, single-family home with a multi-car garage represents a choice, it is in Calthorpe's view neither a preferable nor sustainable one.

Of the many raps on urban planning post-World War II, one of the biggest was that it was led by the head and not by the heart. Engineers made precise calculations that yielded efficient highways but not much by way of soul. Though that trend has largely been abandoned, the release of a new, ambitious study may usher in a new approach to empirically based planning. 

When Pasadena first began to transform its moribund downtown into Southern California's premier urban destination, neighboring Glendale took a more cautious approach to urban renewal, which is to say that it did very little.

But that's changing. Earlier this year, the city's Planning Department established it own Urban Design Studio with the intent of enhance existing urban character.
