LOS ANGELES—For as long as I can remember, civic leaders in Southern California have been touting "regionalism." They insist that an area as interconnected as Los Angeles and its satellites really ought to coordinate how it grows and what it invests in. This sort of rhetoric usually goes no further than sparsely attended final panel discussions at a conferences about leadership or land use or some such. It's hard to "be regional" when everything from county boundaries to uncooperative public officials keep everything in its respective silos. 

A courtroom is not the location to settle disputes over regional fair-share housing allocations. So ruled the Fourth District Court of Appeal on June 30 in a closely watched case involving the City of Irvine. As a result of the ruling, the city apparently is stuck with having to plan for development of 35,000 additional housing units � equal to about half of its existing inventory � over the next five years.

The Southern California Association of Governments has unveiled a new "conceptual land use plan" that concentrates development on a half-million acres of land near rail, bus rapid transit, and local bus lines in the six-county SCAG region. Initial numbers suggest that this plan would only get SCAG 60% of the way toward the region's likely SB 375 emissions reduction target.

For the first time, the Southern California Association of Governments (SCAG) has included new land use policies in its regional transportation plan. Essentially, the plan calls for infill and redevelopment in urban areas, and compact growth in outlying areas. That type of development pattern would, at least in theory, let more people work close to their job sites, and increase the convenience of public transportation and carpooling.
